Audi RS4 needs more power!

[FERNANDEZ DK]

Hi Guys
Im new on this forum & to this platform (2.7TT)

I had a RS4 back in 2003 (same color) which I got tuned at Dahlbäck Racing to 500hp (crank) back then,
It was pretty fast and I really loved it.
But I sold it in 2005 & bought a Supra TT MKIV, and over the years fully build it to 900+hp.
But I have honest always missed my RS4 and how usable it was.

I finally just purchased a mint Avus silver 2001 RS4 with 120.000km on the clock.
BUT BUT BUT

It really needs to get a lot Faster.
I have a complete build 3.0L short block, I can get for a really good price.
So I obviously want to use this for my build, if needed.

I thought going custom manifolds & turbos (some gt28/gtx28)
But because of the clearance issues, don't want to gamble with the manifolds cracking.

I have also thought a lot on the JHM RS6-RS or the SRM K24(any new experience with these? & whats the highest power made with these?)


Do you guys have some input to some good recipes,on this platform (around 600+whp or more)

Thanks
Danny

a nice tial 770 kit should piss that car off. there's always since turbo though

[f4m0u5]

Agreed, 770s would be awsome, but 4k price range is almost double the srms lol

Not comparing to ur supra but these s4s dominate with 770s.

[Mikse]

What fuel will you be using?

[FERNANDEZ DK]

Im not after the Supra power, but a fast reliable street car.

The Tials 770 are overpriced imho, then I could go the GT route,

Im wery interested in the RSM & JHM

Im going to run E85 (Flex Fuel)

Worth the money,not sure if this is a budget build or going for quality . But tials 770 are a very good choice imo.

[Mikse]

770 are not that good choise with restrictive turbine housing and can barely get 600whp with E85 (<- since he lives in europe). Surely there are a many "600whp" 770 but LMAO those who run low 6s 100-200kmh times!

FERNANDEZ you should go gtx2867 like this guy but maybe with .64 hotside. No custom manifolds, just need adapters for fitment.

[FERNANDEZ DK]

Its not a budget build, but not going for crazy high hp, because it's going to be a DD
So it needs to be a reliable setup.

The $4k for the Tials are ok, but i have to ad 35% in custom tax (Tials price + shipping= total +35%)

[a4kamila6]

Throw two EFR turbos of your choice on her.

[ElementR]

If you don't want all out power, considering going with Tial 605.2's and save some money vs the 770's.

[julex]

everyone keeps forgetting that not enough that tial 770 makes outright more power than other bolt-on options, they also come with BALL BEARINGs, which usually is $600-700 option add-on to journal bearing turbos, if it is even offered. I don't have to tell you what ball bearings do to reliability and efficiency of turbo (much less drag vs journal bearing). That gets these cheaper turbos closer to 770 cost wise but still making less power.

Now, 3L block with tial 770 on E85 can really make some good power. I know my 2.7t with tial 770 on 93 octane makes a hair over 600whp...

You have options, carefully weight them though since you might have other offerings in europe that might get you where you want to be. This outfit makes some good turbos:

http://www.theturboengineers.com/

They make some top notch upgrades but if you thought tial 770 is expensive....

[MikeyB3]

IMHO, it's the supporting mods that make 770s the expensive option. But, I can tell you from personal experience that I wouldnt have my setup any other way.

[FERNANDEZ DK]

I don't think there are room for those??

[FERNANDEZ DK]

It's not because I don't want high power, but its going to be a DD so it has to be reliable, I don't think this could be done with 1000hp, if someone have a recipe for a good high power setup, please let me know.

[jaychen]

I don't think there are room for those??

there is.. extremely expensive.

if you are staying twin turbo, Tial only!

If single turbo, many good choices.

[mikeb17]

If you can wrench and are decent with fab work then you could go the single turbo conversion route for the same cost of a proper 770 build. That opens up quite a few doors for turbo options as well.

[FERNANDEZ DK]

I have had a look on the TTE950, but its not just the turbos needed for this power.

If it where a 2jzgte engine I have the recipe for that hahaha
Hoping someone have for this engine.

Is there any build treads with these?

Single is not a option, it has to look semi stock (police/inspection)

lots of build threads.

check the section for it.

srm....junk compared to tial.

[a4kamila6]

You can definitely fit BW EFR turbos down there. Im going single turbo EFR on my 2.7. A twin turbo set up will cost more i believe.

with EFR's haven't seen any

[jaychen]

with EFR's haven't seen any

oh, not with twin efr's. Scott Mackey did it.. I don't think it's worth it. They are huge turbos (length wise).. its just not that practical.

i also dont see a point when the new xona tial turbos are really as good as it gets for the 2.7 motor.

[FERNANDEZ DK]

what about the drivetrain, how strong is it?

[S4gasm aka LOTR]

I love my SRM K24's, I hit a couple fitment issues early in my build but was able to fix them all with a little work. See my build thread below if you care to read.
But they are beastly make no mistake, i put down 520whp on 91 oct and water/meth injection.

[t28sentra]

Running JHM RS6-R for over 30k miles without issue. Previous owner went 11.74 @ 124 (full weight avant). These should be considered if you don't want to spend the money for the Tials.

[FERNANDEZ DK]

How much power can the SRM & RS6-RS make (the new rs have billet wheel also)

The TTE950+ can be purchased for around the same price as the 770r, but what is needed to do on this platform, to exploit there fully potential?

how much boost are you running with?

[Blake2423]

Get these turbos

http://www.audi-sport.net/xf/threads...-s4-b5.263965/

and talk to these guys for supporting mods(like manifolds, inlets and so on)

Forget the Chicom knock offs unless you are on a budget

IMO the Chinese stuff will fail at a alarming rate at European extended 300km/h+ runs no matter how much of "high zinc" oil you are using

I haven't put the car on a dyno, but trap speeds suggest in the 450whp range. It's significanly faster (on the big end) than my previous B5 stage 3 EPL car with meth.

finally, someone with some real common sense when it comes to power:trap speed. 124mph is a fast car. period.

pretty sure sean claimed 650whp and only trapped 128mph

I know that they use The Tuner manifolds & TTE turbos

But whats the recipe to make it hold the high hp, is it just build short block & 2.8 heads & cams.

I don't just wanna send it to a company to get it build

I'm running 26PSI on 93 octane. The 1/4 mile run was on race gas and high 20s PSI. I'm hoping to get the car back to the track this season with the recent JHM R-series clutch.

[frrg]

The TTE products look like they are very well put together. Since they are in your backyard you should check them out. Good luck with your build.

I thought it was made very clear, those numbers are bogus.

[Yuppie]

In you really want to stick with JHM and SRM size/style turbos then I'd go with modified BW rs6 turbos.

[Mocke]

I thought it was made very clear, those numbers are bogus.

Wasent this the car that did 3.5fats or worse and was dynoed on DynaPack?
It should really be dynoed on Mustang.

The problem was applying SAE correction to a location around 5,000 ft above sea level which exaggerated the adjusted results.

What was the numbers without SAE corr?

Btw. How about your TTE550s. Solved that bult problem? Insalled and tuned? Happy with the results?
