Max whp ever made with Tial 770

[Meow]

I love this thread. I've also got a 770 car.
{...}
The engine internals were fully balanced and the flywheel was lightened and knife edged. The 2.8 heads were ported and larger valves added. Solid lifters and custom cams round out the top end work. The intake is a custom RS4 manifold with an enlarged plenum and drive by cable throttle body pulling through Apikol SMICs with NOS serpentine I/C spray system feeding ID1200 cc injectors fed by a custom fueling system comprised of an Aeromotive in tank fuel pump feeding the surge tank and an external SX Performance 18203 fuel pump feeding -10 lines to the custom fuel rail. Engine management is provided by an 034 Iic system which allows maf-less operation.

The car did pull 620 hp at the wheels on a very conservative tune with E85.

This sounds about right. Sounds like a very solid fun car for agressive street driving and mild track duty. 620awhp is realistic and appropriate for those turbos on a mild e85 tune on a standard mustang dyno.

also, dynos sucks, here is why.



Each dyno can be calibrated differently so internet braging rights are dumb.

I only have 518 whp 2.7 heads no methanol EPL tune. wish it was much more though

The question is how fast your car is. I only made 490whp with N/A heads, meth, etc EPL tune and wish I would have got a tune I paid for. Money was well acceped but only a few revision was given.

[landfill]

^^^For 605's 490awhp isn't bad on a stock
motor and decent tune. If your a built motor
I would expect EPL or whoever your tuner is
to get you some files above 500awhp. I'm
guessing you don't have good support from
tial and epl from across the pond.

I love this thread. I've also got a 770 car. This car was not built to run quarter miles but was built as a track/aggressive street car. At one point I thought it was gonna be a Stasis poster car. The rear diff was rebuilt with cryo treated internals and limited slip. All 4 axles were given the full race treatment by CVJ axles. The transmission was rebuilt with cryo treated close ratio gears and limited slip. the center diff was given the 4:1 massage. A lightweight steel flywheel and custom race clutch were sourced from Southbend. The engine internals were fully balanced and the flywheel was lightened and knife edged. The 2.8 heads were ported and larger valves added. Solid lifters and custom cams round out the top end work. The intake is a custom RS4 manifold with an enlarged plenum and drive by cable throttle body pulling through Apikol SMICs with NOS serpentine I/C spray system feeding ID1200 cc injectors fed by a custom fueling system comprised of an Aeromotive in tank fuel pump feeding the surge tank and an external SX Performance 18203 fuel pump feeding -10 lines to the custom fuel rail. Engine management is provided by an 034 Iic system which allows maf-less operation.

The rest of the car has similar attention to detail which provides a very precise driving experience. The car did pull 620 hp at the wheels on a very conservative tune with E85. This is enough to provide a spirited drive without being edgy. I always do have the ability to call up more but I'm happy the way things stand. What a great car and experience.

Hap, wit dakine driving thoughts from Vadaboost, Maguire

Can you clarify, a crank can be knife edged but not a flywheel

Solid lifters ? What's your valve lash adjustment intervals ? Who did the conversion , are you running Cat cams and how far beyond 8k are you reving ?

I have 770 and fully build engine. I can't say I get good or bad support from EPL, I don't get any support. Latest revision (3rd rev) worth mentioning is from December 2013.

Did your car have issues or something that was making tuning difficult? Sounds weird that they would just stop supporting you if your tune wasn't done.

Get a hold of Josh at Solo. He has bent over backwards tuning my 770 car. Like 10 revs in at this point (fine tuning), and offers suggestions when the car doesn't respond like he anticipated. I can't say enough about Josh. Good dude.

[Mikse]

No bigger issues. After Dave left from EPL so did their customer service. Some revisions had some weird behaving, timing curve could be better especially in the summer, every tuner can make decent timing curve when doing pulls on winter. I lost my hope getting tweaks maybe 4 months ago. I'm running on 27,5psi and have asked more duty, asked to lower the rev limiter from 8200rpm etc. and haven't got even a reply.

Questions, questions. Olde Skewl hot rod tech. Knife edging the crank has nothing to do with the flywheel. Its all about less parasite drag and lower mass to spin up. After the modification, the whole lot of rotating pieces were balanced. My mechanic Dave Jones did all the building. He determines the adjustment intervals. I also have solid lifters on my I-5 AAN 2.5 stroker. The cams are custom proprietary cams specifically ground for this application. Right now the soft rev limiter is set for 8250.

[Drehmoment]

Huh, you can't knife edge a flywheel....there are no counterweights on it and it is dry not wet... One more time you said your flywheel was knife edged which is impossible ....lightening it yes and balance the recip mass , sure.

Knife edging means reducing slosh created ( "cutting " better thru the oil sump in lay mans terms) by machine edging the counter weights which also reduces crank weight

Sorry guys. My mistake. I meant to say the crank was lightened and knife edged. Humble apologies.

[Drehmoment]

No problem

Do you know how much the machine shop took off and what was the final weight?

That is a great build you got there and to the best of my knowledge the first knife edged crank on this board.

[landfill]

Same on my 3L crank. Can you supply the name of the company who made your 2.7t cams by chance?
I'm using the smallest CAT variant (264/250) with the oem hydro lifters which I really regret. I didn't
know that CAT UK made cams for solid lifters all the way up to 291/278 or 279/278. At the time I made
that decision it was before I decided to go all out and I didn't want to mess with valve lash adjustments.

I should mention that the car was built by the mechanic who works on my other car, a urS4. It was built at the same time mine was for a mutual friend. I bought the car from that guy about a year ago so I now support 2 hot rod Audis. I therefor don't have all the pertinent information. You ought to see all the other details on this build.

The urS4 is getting a billet stroker crank and has put down 755hp at the wheels. This newest build should see it at 850+ at the wheels.

[landfill]

Yea I'd say your doing things just right. On my bucket list
is a urs4 with a 2.7L stroker fully built with at least 70mm or
more of turbo.

Lovin all the polished goodness under the hood. Also are you running dual exhaust on your Ur?
Pretty interesting considering I've never seen a c4 chassis with a dual setup. Also 19's or 18's
on her? They look pretty big. I had 16's on my ur lol.

Single 3 1/2" that splits to dual 3 1/2 that necks immediately to dual 3". The problem was a lack of 3 1/2" muffler choices. Those are 18s required by the 355 brakes up front. I had the same 18" challenge on the B5.

[landfill]

Damn she's clean even underneath. Mine came from delaware which says it all.

This is not possible on a 5 cylinder turbo car. Or any single turbo car for that matter. And equally not likely on a car with an odd amount of cylinders, but I guess possible.


It is pretty neat to see what you S4 guys are putting down. Makes me feel like my tiny 320awhp from my 4 banger is weaker than all hell.

Here's a good question for you guys- anyone have first hand experience on fully built 2.7 versus 2.8/3.2 vr6?

[LINDW4LL]

How do you figure? I mean, obviously you're only going to have one downpipe initially off of the turbo, but you can then split into dual which many cars do.

Well sure, I could make a quad exhaust coming off a weed whacker if I wanted to.

Dual exhaust means one, separate pipe for each bank, assuming only two banks. I can split one pipe into however many I want, but that doesn't make it dual/quad/whatever.

[landfill]

Alright if you want to overanalyze my statement I guess you could. In the urs4 world there is only one
exhaust outlet on the left side of the rear bumper. He has a dual exit setup with one muffler on each side.
Yes I realize it's all coming from one down pipe off an inline motor your not informing me of anything new.
I've owned 2 of those cars. People have also done this to b5 a4 1.8t's and b5 s4's. So yes it's very possible
to have a dual outlet exhaust on any car you choose. Just not a TRUE DUAL!!! Use your search bar.

You have by far the coolest urs4 I've ever seen I'm jealous sir...

Who powdercoated your wheels and what color are they? Only reason I ask is that I have the same exact wheels on my s4 and I want them refinished just like that

Why thank you sir. Those are actually hand polished. I do have another set of the Koseis on my B5 S4 for winter wheels and they are powder coated. They came out almost as good as the polished ones. Take a look. The were done by Spec wheels in Denver, CO.

Are you running a 551K RS4 box?

[Mikse]

No, originally D-box with M-box tune. Why ask?

[UkuRiSh]

anybody in tri-state area with Tial 770 or similar wanted do couple friendly pull on highway?

Ahhh semantics... to most people dual exhaust just means two exit points at the rear bumper. Nothing to do with the true duals off each side of the motor. Almost all dual setups like that have x pipes or h pipes to cross flows.

[y3ti]

We need some Audizine 'I heart semantics' stickers made.

Here's mine with massive missfire. Yeah I know, I should have done 2tsi coils upgrate before. Anyway, the low MPH is due to missfire at high load in 4th gear. So that11 flat run was done in 5 gear to keep rpm below 5000 rpms where it would start missfire. 1,2,3 was correct which gave me good times.


This is not the 11 flat run in the video down below ,as I was filming ;-). A friend of my was driving my car in this run.
but still 11.46 with massive missfire.
I use to run 129-131 mph quatermile when not missfiring. But anyway, it gives you an idea of the torque.
Listen to hoosier drag radials spin in second gear!

I was just about to congratulate you on the 11.46 pass that your car did, but then I saw the excuse of why the car didn't do better. Please stop with the excuses.
