not true.. you can run on a stock block with no internals done and still have a 450whp beast with RS6 turbos.. mine is a dd.. i drive to work each day.. and push it hard to its limits numerous times a week. methanol injection will help tremendously to get that power safely for your car. but running a stage 3 on K04's you have a better chance of blowing the turbos.. not so with the RS6's.. they have much more potential so you run them very un-aggressively for what they can do.. and honestly if you have a good tune, your K04's wont have any problems either.. talk to someone from VAST or EPL... they all have dd with RS6 turbos on a stock block and jason at JHM rags on his K04's as a dd and i think he is actually putting RS6's on his as we speak, even though hes building his block so he can put more power to the ground..

 

yes it is expensive.. even though the B5 S4 is the most mod-able S4 out there compared to a honda or something or other japanese cars where turbos are all over the place on ebay and you can throw them on in a matter of 4 hours.. the number of built mitsus, evos, hondas and subies out there still is way more than these audis, so yeah.. supply and demand hasnt come into full circle yet... its not on our side yet.. i do know the price of K04 and RS6 turbo kits continue to drop as the market continues to add more suppliers for these turbos, also im sure that the 700whp GT kits are bringing down the competition(k04/rs6) prices as well..

 

Yes, I am looking to pick up a 2005.5 A4 and my plan/goal was to get the K04 kit from apr or something then if what they claim is true 318awhp will just be fine for a daily driver. And run 100 oct when I wanna and that should get me close to 340awhp or even more. But I am starting to see that's not the case. What people don't know is getting 400awhp plus on daily driven cars is scary. My goal with my 3000gt was 650awhp but when I got to 550awhp, I said that' was scary enough lol.
Has anyone experiment with E85 yet on the Audi?

 

how about the Hybrid Owen K04?? Any good take on this??

 

I have close to 400 whp on my K04 setup, but the great thing is the boost doesn't kick in until about 3200 rpm. Other than that, when I drive around town I never go above 3000 rpm when shifting.

I used to race motorcycles and rode a 9 second bike daily that was geared extremely short. It was the same scenario though; throttle control and understanding the power band is all that matters. The car will go as fast as you tell it to, bottom line.

 

Great, just what I have being lookng for. Is it on a 2.0T? What are your mods if you don't mind and what fuel are you getting those numbers with? I like to stay in the 350awhp range.

 

Talking back in the thread.....what's the stock wHP for a 2002 S4?

 

250 at the crank so like 200whp... and yeah.. my boost really starts pushing at 3000, at 3800 its full bore 23psi.. so just keep it under that and you dont have to drive it like a race car all the time.. and no. with 400whp im sure its a 2.7t S4....

 

Woops, sorry to be misleading but I've got a 2.7TT. However, a friend of mine had about 350 whp on his 1.8T using a GT28RS. If you want more information I could most likely ask him about specifics of his setup.

 

this is an S4 forum.. its not your fault someone else was in the wrong one.. how many S4's do you know that come with a 1.8t or a 2.0t???
