Now, this isn't a kill by any means, but more of an answer to a question about the Stage 3 Audi S4's that I have read so much about..
I have been curious for the longest time as to how much HP a Stage 3 S4 puts down to the wheels... Never found any info in the Audi forums, but did find dyno pictures from the manufacturers of these kits, which show 420 (94octane)-450(100octane)HP at the crank.
I found the answer, and it ain't as much as you might think, for as long as you might think....
I found the answer to that question over at NASIOC of all places, from a post made by Shiv of Vishnu:
The link shows a thread about ecutek, with the dyno figures of the Stage 3 S4 on the dyno verus the Porsche 911 turbo (stock) on Shiv's Dynodynamics dyno...
Seems that they might no be making 420HP afterall at the crank... They actually make 20whp more than a tuned VF30 TBXS Stage 4 or VS2 car, which equates to 360HP at the crank on the dyno dynamics.
As you can see, the dyno sheets show the Stage3 S4 and a 415HP Porsche 911 Turbo on the dyno. The 911, with 415Hp from the factory puts down a good chunk more WHP than the 420HP S4.
The most eye-opening part of all of this is how much power the S4 cars drop after repeated runs on the dyno... Down to Vishnu Stage 0 levels of HP after just a few runs, which in iteself does not make too much more than 200whp on a Dynodynamics dyno
So perhaps the next time you come across a Stage 3 S4, you should not be so timid to give it a few runs... You might lose the first, and second race, but the more runs you ask for, the better your chances are of winning
Now, I'm off to go Stage 3 S4 hunting
