Teaser- Twincharged B8 S4

[SoloMotorsports]

The car is making good power and we have worked through several hurdles. Testing continues to ensure we can release a reliable and safe kit.
We plan to release the kit making over 500whp on 91 octane.
Enjoy the vid :)

We are running catless without issue. Egts stay in check even when performing big gear pulls.

[raudiace4]

Fuck me.

[Drof]

how long has your beta kit been on the car / how many miles/pulls have you done with the stock motor? interested to see how it holds up

[IanVr6]

Well, the 1/4 mile run we saw previously was very dissapointing.

[drob23]

Isn't the much bigger problem IAT post blower? Assuming this is a series config and you are using a big CPS...

[SoloMotorsports]

Yes, when developing something like this testing is important.
Disappointing 1/4 mile times is sometimes a part of the testing process.
We have been developing and testing this setup for close to a year now. We have done hundreds of pulls.
We are testing the car at much higher power levels than we intend to release as a production kit to build in a bit of safety margin.

No we don't have iat isssues. Our iat's have remained on par or better than stage 2 iat's.

[IanVr6]

Are you making 93 and 100 octane tunes as well?

[saxon]

6 speed only or dsg as well

Thanks for sharing

[apexit1]

Nice to see it coming along, any idea on a release date? btw check the spelling of porsche on the youtube video

That's how it's spelled....when someone thinks it's a single syllable...[:p]

If you price it really high, people will think this is awesome and then West will buy it from you... I probably won't ride his bumper anymore after that...not because he'd be fast...because I'd be afraid he'd lift and melt my front bumper...

You'd think that for a catless system, they'd be more focused on high octane tunes since street use is going to less relevant than guys looking for trap times.

[Usa]

Wow, sick.

[Jabroni1485]

Doesnt this car have a built motor...

[saxon]

Last I spoke with him it was still the stock motor, although the sleeved one looks bad ass

[AnotherJake]

Awesome. It's nice to see the stock block handling that power.

[Jones2012s4]

Awesome stuff! I love innovation and pushing the boundaries and limits!

Hope this comes out nicely.

People told me I was mad when I plugged methanol into my intake pre charger, apparently all these "buy it off the shelf Audi guys" as I refer to them became methanol injection experts over night.

The S4 you're talking about belongs to Shawn I believe. He has the only twin charged S4 here if I'm not mistaken.

[SoloMotorsports]

This car is still on a stock motor.
As of right now the kit will only be for a 6 speed.

However Sean@Silly Rabbit does have a built motor ready to go in once our stock motor testing is done.

[scrofas5]

awesome. definitely looking forward to this infuture develpment. i think 500whp is more than perfect for an everday car like this. will the kit be compatible with dsg?

[joewhy2k]

Sean's put down somewhere around 600 cheeseburgers.

5 liters everyday for the next 10 years.

[SoloMotorsports]

I think most people will be pleasantly surprised.
We aren't ready to announce pricing or contents of the kit as none of that is finalized.
As testing progresses and we get the parts list locked down we can release that info.

Sean@SRM has put a lot of thought into the little things that will make this kit very friendly as a daily driver. He can do this since he has been driving the kit on his car quite extensively.

[brooklyn86]

May have read it somewhere but are you guys running the Eurocode clutch setup on this car? Is it holding up ok?

[Norm_S4]

Will this be available in Canada?

[RudyH]

ironically that's how much oil the stock engine burns too! :)


Should be quite interesting, ETG, do you have plans to test the limits of the 3.0T or did you guys research the breaking points? Curious / lazy to search myself if it has been done before.

I've heard they have a few test engines for testing the limits.

Yes the Eurocode clutch is holding up great to all the abuse.

Yes

It's true.... When releasing a high output kit like this we must find the limits and give ourselves some margin for safety.

[cspcrx]

This could be EPIC! Might also put some pressure on APR and their Stage3 kit. Competition in the market place is a good thing for the consumer. Keep us posted!

[IanVr6]

No we don't have iat isssues. Our iat's have remained on par or better than stage 2 iat's.

I'm by no means an expert on twincharged engines, but is heat less of an issue by using a series twincharger compared to just a larger blower?

Wonder why APR didn't go this route seeing how many issues they seem to have encountered.

Obviously this kit will make more power.

Most likely due to ease of install, less iat due to a fmic I'd imagine

I think IATs could be a big hurdle with this kit. Running the turbo and charger in series will drop the overall compression efficiency. If the turbo and charger normally operate at 70%, the combined efficiency will be 49%. Normally the charger compresses cool, ambient air, now it'll be compressing hot turbo air. Putting an intercooler between the two could help but only so much and it adds complexity and will be competing for front end air flow.

How did you come up with your 49% efficiency calculation? How much power do you think they are making on 91 octane?

[drob23]

He was just stating the fact that the total efficiency of compressors in series is the product of each (.7 * .7 = .49).

I understand the math, I want to know where he is getting the 70% efficiency rating.

Why is it obvious?

What if they're using the supercharger for low end torque and then opening up the bypass valve and letting the turbo do the pressuring up top? You can't hear it in the latest video from the OP, but in one of the other videos, you can clearly hear the supercharger whine cut out as the turbo spools. By opening the bypass valve on the supercharger, they wouldn't lose any manifold pressure but they'd get rid of additional PSI compression from the supercharger as well as the heat generated from that. At the same time, they'd also be able to utilize the ICs in the supercharger manifold to intercool the now turbo pressured air. Remember that turbos don't heat up the air because they're exhaust driven, (the air sits in those areas very little time to pick any of that heat up), the air heats up due to pressuring it and exciting the molecules.

Now I can't be sure this is exactly what's happening, but it does make sense and can easily be done. It wouldn't be the first time someone has used a roots blower for the instant torque and then let a turbo take over once it's spooled up.

[drob23]

I understand the math, I want to know where he is getting the 70% efficiency rating.

Just making it up to make the point that the entire system will generate heat, that's all I take. No attempt at real numbers.

Turbo should be more efficient while our roots charger should be much less, at least from what I've read. But maybe you can simply open the bypass valve at high RPM or the wastegate at low, I don't know much about how this works or what the optimal control strategy is.

Edit - looks like swank beat me to it lol.

[F16HTON]

I've been in the car, bypass valve is not opening.

[05blacks4]

Nice

[Norm_S4]

Ok so this being a teaser thread; can you say someone would be able to go from stock to this kit?

[AQuattro]

I understand the math, I want to know where he is getting the 70% efficiency rating.

Just a ballpark number to illustrate the problem. 70% efficiency is typical for turbos and TVS chargers.

[AQuattro]

The bypassed air will not all need to go through the screws, all bypassed air still enters the engine, it just bypasses the screws. So it is not compressed again.

Isn't the bypass after the screws? Anyways I edited my post, I was thinking the TVS was a twin screw charger but its based on the Roots style so there will be no additional compression with the bypass open. IATs could still be an issue since the stock intercooler might have trouble with the additional air flow.

Why is it obvious?

In a series twincharger setup the turbocharger is mainly making the power. The blower is there to spool up the turbo so you have no lag.

There is more power potential using a turbo.

Correct me if I'm wrong.

[AQuattro]

There is more power potential using a turbo. Correct me if I'm wrong.

In a perfect system yes but adding a turbo to an already supercharged engie introduces a bunch of compromises that could eliminate the advantage. The charger will restrict the air flow from the turbo and adding additional intercooling will be difficult. I don't think there's a clear winner on paper with what we know so far.

The blower doesn't spool up the turbo, it compresses the charge before the turbo can get going (low RPM or low load). Presumably, they chose a big turbo that will move a lot of air at high RPM and high load. Curios what type of turbo's they chose since our car has dual manifolds, also there's the issue of cooling the turbos etc. But you want to retain the drivability/throttle response of the S/C at low load. Otherwise, might as well make it strictly turbo.

You think the charger will restrict airflow? With the bypass valve open, I'd think it's no more restrictive than the stock intake hose? I drove a Ricardo twincharged 1.0L fox engine application, and the supercharger was electronic. I don't recall whether there was a separate compressor, or if it's functionally the same as the MGU-H units in the new F1 cars. The nice thing there was the compressor was electronically driven, so there was no drag on the crank after the turbo took over.

I think this car will definitely need a big CPS when the blower and turbo are combining their efforts, as you mentioned earlier. But it's plausible that up top, the IAT's are better than stg 2 because the turbo compressor is more efficient and bypass valve is open, thus, not exposing the blowers inefficiency (hence why APR is switching blowers to make more power). But I think the control problem on the 3 actuators (bypass, wastegate, blow off) is trickier than what APR is doing, especially if you're trying to tune it properly over all operating conditions vs strictly top power under WOT.

In this setup, yes.

Generally speaking, a centrifugal supercharger makes respectable power as well (mid to top-end).

With APRs financial troubles I wonder if this is our only real STG 3 offering? Of course nobody has a proven working system yet. Personally I'd like to see this setup succeed. But I'm guessing it won't be cheap? At least not less expensive than a bolt on blower.

The price range Sean mentioned to me for the kit, if it hasn't changed, will definitely surprise you.

[IanVr6]

Some people wouldn't care if they had to change the car's internals if it makes more power and increases reliability.

[hodrosS42001]

SRM has built a very good reputation in the B5 S4 community for delivering a good product for a very competitive price.

I wouldn't be surprised if and when get this kit all sorted it might only be around 5k and be absolutely worth it.

And yes they are working on built 3.0 engines.

[Schadenfreude]

I hope this kit succeeds. Since the "Killer B" rally cars I've always been fascinated by twincharging. It would also make the Stage 3 cars something truly special, dare say exotic, on the road. Would I go Stage 3? Not sure. Out of warranty, Stage 2 is a certainty as I plan on keeping my car a long time and the extra power will feel refresh my love for my B8

I dont know about others, but for me , a lot of the decision to plunk down for a stg3 is gonna depend on the b9 s4's engine. If its turbo charged, I probably will leave, but it seems that the rumors are that it is also another supercharged 3.0... if that's the case, Ill stay with my b8 and seek out something stg3.

Im surprised MTM hasnt created anything for it yet.

While I have my sites set for the next RS5 which will hopefully be lighter and TT, like you said, if no major improvements to the powertrain or weight savings, I will most likely keep what I have and build her up.

Stage 2 is enough for my B8. If I need faster, I will simply buy a much faster platform and build that up. That being said I would love to see some B8s run into the 10s.

[SoloMotorsports]

A little update:
We now have a built motor in the car. The block is sleeved with upgraded rods, pistons, valve springs and hpfp.
We also ended up going with a slightly larger turbo [evilsmile]
Here are a few pics to show how the kit has evolved throughout the testing process.
I'm sure some of you will appreciate the implications of a top mount setup.

I've been waiting for that question to be asked. The answer I can give is that IAT's have been addressed, quite ingeniously I might add. This kit doesn't require water or meth injection. Currently we aren't running any water or meth injection.

[Auditude2.0T]

First off, props to being the first guys to go out and try something different on the B8. That being said I'm not sure different is better in this case..


A few questions and concerns. Most guys here will all jump on board, asking stupid questions and getting excited for all the wrong reasons.

You guys came on here a few months ago and showed us a pretty shitty quartermile time and some boasted dyno numbers. Granted bad times and numbers are always part of the learning curve however now you guys come back with a built motor and a new kit?

What happened with the stock motor? Did you find its limits? Did it blow up? What did it hold up to? Did it ever make power? Most guys here are not building their motors and realistically we want a kit that makes this a low 11 second car on pump and I don't think you guys did that. You blew the motor most likely, waited a few months and now come back with a built motor which to me is useless if your looking to make sales...

Why have you chosen twin charging? Why not just go single turbo, perhaps a GTX30R or GTX35R. A GTX30 makes the power of a 35R and spool like a 30R.. A 3.0 V6 should spool a 30R by 2700RPM and make full power from 3500-7200. That to me seems like the logical solution plus just staying air to air cooling and so much less heat.

I would like a full explanation on what happened to the stock motor.

You guys came on here a few months ago and showed us a pretty shitty quartermile time and some boasted dyno numbers. Granted bad times and numbers are always part of the learning curve however now you guys come back with a built motor and a new kit?

What happened with the stock motor? Did you find its limits? Did it blow up? What did it hold up to? Did it ever make power? Most guys here are not building their motors and realistically we want a kit that makes this a low 11 second car on pump and I don't think you guys did that. You blew the motor most likely, waited a few months and now come back with a built motor which to me is useless if your looking to make sales...

Why have you chosen twin charging? Why not just go single turbo, perhaps a GTX30R or GTX35R. A GTX30 makes the power of a 35R and spool like a 30R.. A 3.0 V6 should spool a 30R by 2700RPM and make full power from 3500-7200. That to me seems like the logical solution plus just staying air to air cooling and so much less heat.

I would like a full explanation on what happened to the stock motor.

Did Swank steal your account? j/k

I'm curious about the move to a built motor as well. I think we'd all like to know the limits of the stock internals

While I don't mind the twin-charging method, I would be very interested on a single turbo setup that deletes the stock SC and replaces it with a custom intake manifold.

Yes we have found the limits of the stock motor and identified the particular part which is the limiting factor. This information is quite valuable at this time and cost us quite a bit of time and effort to gather and analyze. You can imagine us not just posting it openly on the internet until we have completed what we set out to do [:)]

The low end power difference between twincharged and turbo only is quite drastic which is why we're pushing to get a twincharged kit released.
I'm sure at some point we will have demand for and produce a turbo only kit but as it sits now the twincharged setup outperforms the turbo only, using a pte6266.

This being a teaser thread we are happy to share some of our progress and a few particulars about the build. We cannot release full details until we have a production ready kit.

I'm sure you won't need more than 2 weeks to find out the limits of the new internals.

[Auditude2.0T]

They have like 12 names

[USAFS4]

Well, big promises. Would like to know if your future kits include a build using stock internals that exceeds current stg 2 offerings. I would hope for your sales potential that your kit with stock internals is reliable to 450 whp 400+ torque. If not this is a Halo product.

Don't get me wrong this a cool build. Best unproven kit out there. And I hope you are the first to produce a reliable 500/500+ car. Best of luck.

[Rob01S4]

It's torque that bends rods or makes bearings fail on an otherwise properly tuned motor. I'm also curious as to the torque limit of the stock internals. I wouldn't be surprised if tuning this system on a stock motor would require limiting torque output.

[LINDW4LL]

I'd guess that the stock rods start bending around 500wtq.

Stock 3.0T uses Powdered Metal rods. The S8 probably has better connecting rods & pistons for something like this.

Wonder if these guys would have a stage 3 limiting torque and a stage 3+ offering forged internals.

[Rob01S4]

That's the way I'd do it if I were offering a full kit that includes a tune. Timing and torque conservative.

[IanVr6]

ETG, do you guys know the sales potential of this kit if it actually turns out to be a high power/reliable kit and is the first one out?

Maybe there is not much power to be gained with stock internals after stage 2 with this engine. APR probably knows this as well.

If anything fails it'll almost always be the pistons first. People wondered the same thing about the BMW n54 and a stock block recently pulled out 829WHP with a big single turbo.
http://www.bimmerboost.com/content.php?5325-The-BMW-N54-horsepower-record-stands-at-829-wheel-horsepower-thanks-to-a-Motiv-Motorsport-single-turbo-upgraded-335i

Lot of other N54 examples pushing north of 500whp for a while with no real problems other than the occasional piston/ring problem from people beating on it with tuning issues.

If an engine is boosted OEM, they are usually built pretty stout with modern engines having nice power metal forged (PMF) rods but the pistons are a different story. The pistons have to run tight piston to wall clearances (vs a race engine) and the ring package is designed to minimize crevice volumes which contribute to emissions significantly. They simply can't take sudden increases in heat, expand a little and either pinch the rings or the piston crown catches the unlubricated top of the bore and breaks a piece off.

The fix is just to design a piston which can handle the heat better, use better ring package and just loosen up the piston to wall clearance a little.

With good tuning control I would think the 3.0T can go a lot higher in power but the OEM supercharger design seems to have real issues with its heat exchanger's ability to pull heat out of the intake air given the amount of boost needed to make real power. The S55 in the BMW M3/4, for example, seems to have a MUCH better heat exchanger as evidenced by some recent runway roll-on races showing IAT staying below 125'F in 70-80'F weather on a full 1/2mi power pull at 25psi and probably 500-540WHP.

[jayr1987]

Any DSG testing coming?

[Jgm22]

This will be great for this platform. Is there any tentative release date?

[Steve416]

Also, I thought I read somewhere on here that the DSG tranny is only rated for 450 tq. Some guys on here must be getting pretty close to that just with their FBO stage 2s on race gas. Not sure there is much more headroom with stock tranny and motor.

[DGVR6]

This car is still on a stock motor.
As of right now the kit will only be for a 6 speed.

Gotta read the thread.

There are clutch pack upgrades available if you're building the motor might as well upgrade the dsg as well.

[somedude]

I LOVE the idea of twin charging. I can't wait to see this thing rocking and rolling in some videos

[613B6]

Thats usually a myth as with the fwd DSG, the clutch packs are usually good for alot more, its getting the enough pressure throught the software to increase clamping on the clutches.

As an example my GTI holds over 500whp through the DSG with over 14bar of pressure logged, bone stock tranny with just software. I would assume this DSG could hold alot more given its built much stronger and has better oiling control then its FWD counter part.

Yep, torque limits are usually grossly underrated from the factory. Even then you have the clutch pack upgrades as posted above. I think the likely issue is that a small company like SRM doesn't want to risk blowing up the S-Tronic on their personal car when they have a manual to test it on.

Yes SSP make the same for the FWD DSG claiming the same thing. A few guys tried them and quickly realized it was still slipping...Think about it as manual clutch setup, you can have the best friction material on the plates however if you dont have a proper pressure plate to hold it...DSG is the same thing. Your worry becomes tranny fluid and mechatronic temps, with added pressure and friction come alot of heat.

[Jacksonbeall]

I had a chance to have my S4 in a feature spot at SEMA this year. The SRM guys had helped my with a water meth solution for my car and realizing that the were based in Las Vegas I got in contact with them so I could go see this thing first hand. First of all let me say that Sean and Kyle couldn't have been more hospitable, I swung my on my way out of town and they gave me a full tour of the shop including all of the design work for the system, how my meth plates had been made and other various projects they were working on. Then they took me out side where a very stock looking S4 sat, that is until he opened the hood! Sweet jesus, right behind the blower was a very large looking turbo system pair yup with a very well fabricated custom cooling system. Sean took the time to go over every aspect of the different design approaches they took on this build and why their current system had produced the best and most reliable results. Honestly I was spectacle if the car would actually run since all we have seen on here is about a 12 second teaser, so he offered to take me for a ride. All I can say is HOLY SHIT TAKE MY MONEY NOW. We did multiple highway pulls and the power is down right scary, the last time I had been thrown back in the seat that hard was when I got to ride in one of our local Dallas tuners upgraded GTR. Then there was the highlight of this entire experience, he took us to a back street and launched this monster at 5.5k, all 4 tires lit up effortlessly and we hit 130 before I could blink. Sean stated that at that point they were only running about 24 pounds of boost but the system had the capability of going upwards of 30. I took a few pictures of the system and I have a few videos of the pulls, all of which I will upload when I get everything loaded from my SEMA trip. I looks like these guys have truly found a solution to create good power in this platform, he did say some of the internals would have to be upgraded to guarantee the reliability off the system, but I fee like thats is a small investment in regard to the amount of power have been able to produce. Seeing and feeling is definitely believing. If any of you have the chance to travel to Las Vegas anytime soon I would highly recommend stopping by and seeing for yourself, their shop was only about 5 miles from the strip! I'll post pics and Videos up here in a few hours! ***Sorry for any spelling or grammatical errors I've been in the car since 2pm yesterday so I'm on the struggle bus.

[Mr.Tan]

i probably missed it in other parts of the thread, but how is the heat controlled from this? i know the superchargers already put out a good amount of heat when tuned a bit, how is it capable of supporting the turbo too? i see the outlet goes straight into the TB and into the SC.

[AudBoost]

^^On page 3 post #111 its stated they solved the IAT issue but don't give much detail. But it does state no water or meth injection.

[Mr.Tan]

^^On page 3 post #111 its stated they solved the IAT issue but don't give much detail. But it does state no water or meth injection.

i'd like to know how they solved it, thats a lot of heat to deal with not using anything larger to keep it cool (or water meth).

[AudiA4_20T]

i'd like to know how they solved it, thats a lot of heat to deal with not using anything larger to keep it cool (or water meth).

If they run low boost and the turbo is efficient they could be fine. Otherwise it could be a big upgrade to the factory S/C cooling system.

Yeah, I'd probably run the intake up there as opposed to just throwing the filter on the turbo inlet

What benefit would there be by moving it up there, unless your talking about ducting cold air up to it.

It doesn't look like there is enough room for a 4" pipe though

You'd get cooler air at the front coming through the grill than at the back of the engine bay on a hot turbo.

[Chuuey]

I know how they solved it.

[:D]

Will let them answer though.
Me too, Sean gives some good info, I'm sure he will share when he's ready!

I think I've just had a crisis...

[IanVr6]

Seems like a big project to get everything in order in there.

Since new internals were put in I'm expecting way more than 500whp on 91 as previously stated.

I don't think you can make "way more" than 500 on 91 octane. You're limited by the fuel.

[IanVr6]

More videos please. I've been a good boy this year.

There is one on FB where he spins all of 1st gear it's sick.

Exactly, 91oct is horrible regardless of the internals

if an e46 m3 can be built up with 800 hp why can't the B8 S4? [evilsmile]

I'll give them a call this week and get an update for Y'all!

i move back to Atlanta in may. I will be visiting regularly then![:D]

[RWD2quattro]

Because our internals won't take the beatings hence why APR will never release the 1740 to S4 crowd.
Upgrade to forged rods and pistons and then slap the TVS-1740 (APR) or custom twin GT2871R turbo's if they can fit. Twins [drool]
Next problem is valve train but EC has a solution for that [:D]

My .02 cents...

[jayts]

Updates?

Haha this was my plan when my warranty was up. Glad to see it actually happening. Amazing progress so far. Can't wait to see more video's.

[Black_V!per]

SRM is working hard on releasing a product for the Turbo 911 (997 to round out their 996 options) while conducting testing on the B8 setup. Daily jobs slow all projects down, but they're still progressing last i heard (2/6).

[SoloMotorsports]

We got to the point we were pegging out the factory ecu on load with a larger turbo. We were testing with a few workarounds and SRM decided that with the amount of money they had into the car and the power level it will achieve it just made sense to go standalone.
We had achieved about 600whp with meth injection on built motor with the factory ecu but with no good 1/4 mile runs or finished product to show for it we haven't really been publicizing it.
SRM has vbox 60-130's in the mid 8's with the car.
I know many of you want a 500whp version but after all the testing we did I'm concerned about engine longevity on a stock motor.
There really isn't a cheap fix to get a healthy 500whp that will last or we would have gone that route.
With the price of the twingcharged kit and motor work needed you would end up spending about $20k.

Bottom line is We made a really fast car but It's just not a mass producible product.

[will13k7]

lol, good guess by me:


my theory is all of these attempts; apr stage-3, twin-charged, etc... can't get the car not to throw codes, or reliably handle the power, or both, so these will never be off-the-shelf productized, maybe some custom one offs though, but with some quirks.

Well that sucks. 60-130 in the mid 8s with 600whp?

Then at least let us live vicariously though more videos [race]

Yes that was great speculation.

yes, mid 8's (8.6 if I remember correctly) @ about 600whp. It was earlier last year.

Lol, I'm sure once the standalone is installed and tuned you will get more vids.

[Legacykid]

I think its really cool, but if people were bitching that the APR setup was going to be 15k. Who is going to actually purchase a 20k kit?

I like most believe stg 3 for our cars is long dead. But im glad that Solo actually said whats going on and why, Respect!

[joewhy2k]

Dear Solo,
Thanks for keeping sh*t real when others wouldn't at all. Appreciate your honesty and transparency with this so props and respect for that.

[saxon]

Thanks for the update, where does the stock motor start needing upgrades to handle the power.

It's actually pretty disappointing since 4 cylinder stock block Hondas make 500+ all day long

[LINDW4LL]

With stock internals?

I believe it was mentioned that about 500whp is the danger zone for the 3.0

[IceFour]

Disappointing to hear but glad you were straight with us. Maybe there's a happy middle ground between stage 2 and having to start building the motor. Sub 500whp

[dubsquared]

What about Stage 2 plus a 50 shot? [:D]

[teylix]

well guess im not getting any more horsepower out of my car :P but mine is a daily driver and 350+ whp is enough to make me happy.

[saxon]

[akenharris]

I hope y'all don't keep thinking this is the end of the road for the B8S4. Not to take away from the twincharger project, I've expressed my interest over emails to Solo Motorsports/Silly Rabbit Motorsport, but we've also been hinted at by AMS of a possibility of a twin turbo kit for this car.

But it is good to hear that we've learned the stability of these internals, being at 500whp. I don't mind upgrading internals for more power though.

Let's not doubt this beautiful work of engineering [;)]

you realize, its not just pistons and rods. it would need to be sleeved due to the type of the cylinder liners this motor has stock. then you would need to do minimum valve springs and retainers to rev higher and handle the power so that valve float doesnt happen.... unfortunately this motor isnt showing to be capable of handing much more than stage 2 without significant investment

[madman4you]

Sad day... Great to hear Solo provide real feedback, vs the marketing hold out from others.

Can't wait to see vids with stand alone setup, and someone go and spend a bunch of money so we can live through you!

Having built a fully built turbo car in the past, I know that once you get into dropping that kind of cash and doing all that work, the car never seems to run as "solid" as factory. To many little things to keep an eye on for a daily driver.

Stage 2 for me and I will ride my bike on days I need to feel the wind beneath my wings.

So what exactly was limiting the block first? Having a lot of low end torque and small displacement can be harder on the engine also so I would think removing the supercharger grunt and parasitic load would free up quit a bit in a turbo setup. I'm sure the factory supercharger intercooler gets to be quite a restriction at higher power levels also. I hope people keep pushing the envelop though :)

I've wondered doing away with the supercharger completely and replacing with a single/twin turbo setup too. Although I'm not an engineer or mechanic so I have no idea if that's feasible.

[LINDW4LL]

It's very possible that taking away the supercharger would allow the block to hold higher power levels, but the beauty of the twin-charger setup is the huge powerband. Of course it's a double win because you get to keep the low end torque while at the same time spooling the turbo much more quickly than a standalone turbocharger setup.

These cars may not make 500whp, but the powerband is so linear and large. I think the large majority of S4 owners would not be willing to sacrifice low-mid range torque for higher peak power.

It would be nice to get confirmation again, but I believe it was the connecting rods first, and then the cylinders were the next weak point.

True. Even though this car is rated at 333hp at the crank from the factory I'm always surprised how much power it feels like it has. I suppose the broad powerband is the reason.

[Chandler]

I want the RS5 motor with a 6MT. Sigh.

It is a great engine though for it's other characteristics. Exhaust note and high revs in particular. This is the closest you'll get in a sedan, and it's like new!

I don't think most s4 owners would want to give up that low end either. For those that do want to go with a turbo kit you will still need motor work.
The issue at hand is cylinder wall scarring which will cause compression losses after prolonged use at high cylinder pressures.
Ring gap, one forum member mentioned it a while back.

The power band on the twincharged setup is huge. It was making over 500wtq by 3k rpms.

Based on what you learned what do you feel the safe max HP would be for these motors?
