B8 S5 N/A Dyno

[S5oak]

Hello everyone, was looking to see if everyone wants to chip in on N/A dyno numbers. Just got my car back yesterday from eurocharged canada, and as far as I have looked, I'm pretty sure I've got the highest hp/tq V8 s5 for the mods. It has an upgraded air filter, jhm test pipes, full 3" exhaust and a tune from eurochared (also did a carbon cleaning about a month ago cause it was pretty bad).
first pull was baseline with test pipes no tune, second pull was with tune and third was e30 mix. There where several pulls but basically the car consistently put down 333awhp just on pump gas which factored for drivetrain loss is ~408hp at the crank. On the higher octane it consistently made 340 awhp with the highest run at 341.74awhp which is ~417hp at the crank.

I was looking to see if anyone was willing to post numbers and see what the records are for V8 S5. Thanks!

I think using a DynoJet will explain the majority of the higher figures, they are well known for over reading but making customers happy.

They've dyno'd multiple rs5's making 365 awhp & 296 awtq which is spot on. I'm well aware mustang dyno's hurt feelings but they are also known to under measure. How about posting graphs instead of going off topic, no offence.

Mine did 249/252 on a dynapack stock on 91 oct. I plan to have another run once i get a tune.

Your S seems to be running very healthy. I think another good tool would be to compare what it can do via 1/4 mile times

I highly recommend deleting the cats with the test pipes, really changes things (car is insanely loud now because I have a full 3" exhaust which I have to change lol) but where I live we have easy access to 94 oct so my baseline of 319awhp was 94oct, test pipes, air filter and exhaust but no tune. Also getting a carbon cleaning done is a must because when I did mine, I thought there was quite a lot of build up for a 95,000km car.
Also the tune was a stage 2 tune from eurocharged with more aggressive timing cause of the bolt ons. The second run of 333awhp was with the stage 2 tune. The highest final run was on e30 ethanol mix but I am excited to get to the track this summer and put down some 1/4 times.

Oh she's not stock anymore I have full bolt-ons minus tune now. Yeh, sucks we're stuck with only 91oct here in SoCal. I have plans to run her at the track as well.

Do you have a stock baseline on that same dyno?

[S5oak]

The stock baseline is on there in red @ 319awhp. But that was already with the test pipe installed, air filter, exhaust and 94 oct, just no tune.
I also very recently did a carbon clean and even after that I felt a very noticeable difference in power but that was from the butt dyno lol
It must just be a healthy b8 because the next highest hp b8 s5 on the same dyno with everything I had minus the cat delete and exhaust but + snow performance water/meth ran ~300awhp and they preformed a carbon clean right before the run. But I was told the water/meth on that car was for reducing carbon build up more than power hunting.

Well now that you’ve said that I can’t take offence.

I did post a whole thread on dyno runs but unfortunately it all died with PhotoFucket, I used a Maha dyno (as used by Audi, BMW, Mercedes, etc) which gave some very honest results and stirred up a real hornets nest but the fact that a car in Germany and another in the UK all using the same dyno made the same power down to one decimal place tells you those machines are very accurate, that’s why the manufactures use them. I just get very sceptical on some of these big power for little mods dyno runs, you’ve gained what, almost 70hp from a stock car? That’s an amazing result for an exhaust, intake and map on a na engine.
Let me see if I can get the maps posted up, they aren’t S5 but they may be something you can compare against?

Look, I like to post messages as if I'm talking in real life, not being a keyboard warrior. For some reason on this forum there's always more speculation & bashing rather than constructive input, which doesn't happen on mercedes,bmw, etc, forums. I'm not going to defend the dyno because I mentioned before other S5's have run the same dyno and run under 300whp with almost the same amount of mods. My highest run I will repeat was on e30 so thats not a surprise gain from the 333whp on pump fuel.

If you're unsure about it making that kind of power check out Jhm's record all motor 1/4 pass with the S5 at 12.6. The Car & Driver 1/4 time for the RS5 stock was 12.5 so that means that Jhm seems to have come very close to that hp level. My car is running basically everything they had on that record setting car plus a few mods of my own. Jhm doesn't like posting dyno graphs and I get why. They post real world numbers, which I agree with and this summer I will make it to my local track and put down some 1/4 mile times and we will see what the results are. The one thing you also have to understand is cars have large differences in power, for reasons like maintenance, and even how you drive your car makes a difference because if you're stuck in traffic all the time with it, its no bueno. Before I did these recent mods, I've taken down 5.0 mustangs and the new ones, 4.7 Masterati Granturismo, 335i, and e92 M3 with mods but I must mention not the greatest driver but still.

034 motorsport has a tread showing the various stock V8 audi's and like mentioned they put down in the region of ~300awhp.
Jhm's S4 also was the highest hp 034 had tested with an ~10whp variance from others they had tested and their dyno isn't a dyno jet.

look at the win vs fail RS4 dyno graphs lol

[Sazexa]

What else have you done to the car? I'm looking to squeeze as much N/A power from it (safely, of course) before going to a FI route.

So since that post I went down to a 2.5” custom exhaust from the Jhm test pipes back. I previously had a 3” exhaust but firstly it was too loud and it wasn’t as effective as this new one. Definitely picked up some grunt at the low end. Other than what I mentioned, it’s got light weight rotors and bc forged wheels with 295’s all around, looks sweet lol.

[MonsoonB8S5]

I just had test pipes, intake and custom tune done plus some other things. Still do not have full exhaust setup yet, I only got rid of the mufflers & resonators and had a custom x pipe installed. 86k miles and NO carbon clean unless the previous owner did it at some point.

Dynojet numbers came out to be 398bhp and 430btq or 334awhp and 369awtq. I can believe it just driving around with it so far. Seems to have much more power and way more torque.

This is with a ecs intake and straight pipe after the cats, wet shot of nitrous on stock tuneIMG_0848.JPG

I just recently had the jhm race pipes installed and order an aem water meth kit, gonna do a carbon clean and throw it back on the dyno to get tuned,

Interesting that the torque came out much higher than hp. But seems to be right on par with what my car is making. A carbon cleaning is a must at that many miles if the previous owner didn’t do one. Trust me I did a carbon cleaning myself on my car, and it will be caked on there if it hasn’t been done and really spoils fuel efficiency & power.

Wow I don’t think I’ve ever seen anyone use nitrous on this platform before, very cool. What are you using? Looks like an 80 shot? And please do give more info on it because it’s very different lol I personally would never consider doing it because fuel is already expensive enough and if I had a toy like that it I’d be replacing bottles daily. Also must be a hassle but do share!

I’m running a .044 nitrous and .022 fuel jets, single port right before the throttle body.

I just ordered a meth kit to run with my nitrous so I can get a custom tune to sneak more timing. Who did your tune?

I’d love to see the numbers after you’re done getting the meth installed and the custom tune.

My work was done at eurocharged Canada and they actually had done work on another V8 s5 that they ran meth on. They ran it so that it would also keep the carbon build up down on the intake valves and also make more power so it’s a great idea. I’m thinking about getting a custom dyno tune as well but I haven’t made up my mind if I’m going to go forced induction yet. Another mad man swapped a 4.0T in his s5 and that sounds unreal with a manual transmission. So idk yet lol

[Ape Factory]

Do you have the SAE Corrected and uncorrected graphs? Having operated a dynojet myself, a lot of factors can come into account which will affect the results. This includes everything from actual maintenance on the dyno to tire pressure.

The STD correction numbers, as listed on your graph, are always going to list the highest hp/torque output as they correct to 60F and a higher barometric pressure. SAE corrected is like 77F and a lower barometric pressure. If folks are going to start comparing dyno numbers (and I'm all for it), they should post up all the sheets. But for me, it's the shape and area under the curve I find interesting, not the peak numbers.

As you said, the drag strip will either confirm or deny your results. Hoping it's the former!

[spense5]

I'm very curious if I need to consider a carbon cleaning...My car threw a fuel pressure code apparently the other day but the shop cleared it..I dont notice any issues right now (KNOCK ON WOOD) and no CEL. My car has 35,681 on the odometer and with normal city driving, minor freeway I'm getting like 210mi on a tank..are you guys getting roughly that?

Got this car 4 months ago and I'm not sure if the prev owner did a CC.

[kevinqb5]

Hey guys so I’m posting an update for my s5

2009 audi s5 tip
Jhm tuned
Jhm test pipes
Luft technique cold air intake
Full straight pipe exhaust(oe dia)
Sniper nitrous kit jet for 75shot
Aem water meth kit( not working )

No dyno after the tune and test pipes but I did go to the drags and recorded the 0-60

put this car on a mustang dyno and you will see 260 270 awhp I guaranty it

Not with that trap speed. It's in line with an RS4 which ideally makes 420 CHP.

I can tell you from experience building and tuning 2 separate port injected 4.2 liter S4's that they max out at 400 CHP or so on the stock intake manifold.

Look at his mod lists and you'll see that he's running a 75 shot of Nitrous. So there's no way he's under 400 CHP.

***EDIT**** I thought Hans was talking about KevinQB5's car, not the OP.

[Fourpoint282]

This ☝️. If you want a true valuation of gains you must do a baseline, then post mod pulls (all on same dyno). I have a B6 s4 and put down 251 awhp stock and 282 awhp after do’s exhaust and tune on 93 octane. This was one a MustangDyno.

Although it would be ideal Jake, you know as well as I do that there's no way that he's installing a set of downpipes on the dyno.

So taking three different pulls 1) DP stock tune 2) DP tune and 3) DP tune E30 gives us all the information we need. Forget the absolute numbers, just look at the delta.

-The tune itself is worth about 12 AWHP

-tuning for E30 is worth about 10 AWHP beyond that

I'd also say that this dyno makes a solid case for running water/meth on these cars which is something I've been advocating to the S4, RS4 crowd for almost 2 years now to no avail...

The gains from the extra timing from the E30 also mirror the losses that a heatsoaked engine displays like what happened to Ape Factory during his last dyno session when he lost about 7-10 AWHP when heat soak set in on the Dyno when he was testing your guys own tune on his RS5 https://www.audizine.com/forum/showt...release/page11

[Ape Factory]

In all fairness, yes, it pulled timing but I also could not get two back to back runs with the same output on that dyno and I don't believe it was in inertia mode. On the dynojet? The numbers were repeatable well within 3% despite being even hotter that day with higher humidity. The Mustang dyno pulls took almost twice as long so there was some sort of loading going on. This is backed up by the fact it practically caught fire on one pull.

I should have just waited til fall to test. 95 degrees in a dyno room is not a good thing. On the Mustang, which either wasn't in top shape or the dyno operator didn't know what he was doing (or both), there was no consistency to the runs. That's more the dyno's fault than the car or tune. I'd like to see some results for water/meth. If I go SC, I'll most definitely run it.

So why has JHM in all it's years never done a back to back 1/4 mile comparison between their flash and the stock flash on ANY platform B6 V6 3.0, 4.2 B6/B7 S4, 4.2 FSI S4, 4.2 FSI RS5...

How hard would it be to take 10 min, reflsh the car between runs and compare 1/4 mile times hmmmmm????

One possible reason would be, I've heard the ECU can take some time to adapt to a new tune, may be BS though. Or not as the tunes are what would be called 'Canned Tunes' much like OEM's do. Problem is every car is unique and in unique conditions from when it's calibrated. So some level of automatic/learned adaptation will occur. This is why every car should be custom dyno tuned.

I love the dyno argument. Dyno's are basically scientific tools. They are very accurate. Biggest variances come from operators, and or improper maintenance. Dyno's and the racetrack both have their uses and one cant really replace the other. Not giving dyno numbers is a cop out.

I totally agree with you about the water-meth. My next step is to get that put on the car and then go the route of a custom dyno tune to get everything running as optimal as possible. I’ve asked a ton about running meth on these cars but it seems like people hesitate or shoot it down. Even when you mention the fact it aids in cleaning the intake valves because of the direct injection these cars have and carbon buildup issues.

Only other guy I know of with meth is Terrance and he’s jhm supercharged.

Really wish apr would bring back their roots style superchargers or even if Magnuson themselves offered a product, I think lots of people would be interested because of the magic of depreciation with cars lol

I'm running water/meth with a centrifugal, no intercooler, IAT Sensor relocated. IAT's are nearly half. Not tuned for it though yet. Cylinders a Def. cleaner, if not clean in comparison. Not sure if its helping with carbon build up in the heads intake port though. Its work in progress. Aside from the purchase price, the added cost fuel wise is well worth while considering you get close to, if not race gas level octane/knock resistance/safety net.
