Thought a few of you who aren't familar with my S4 build thread, might be curious to see a little vid from some dyno runs we did today. All in all, a great day. Both myself and my friend were extremely happy and impressed with the results, and we've spent a long time tweaking and getting things right.
We are doing these dyno runs as a project to find exactly how much power (if any) is gained by going from 2.5" downpipes to wide mouth 3" downpipes. We both are not going to make any adjustments until the next dyno in a couple weeks.
I managed to put down 304whp and 314ft/lbs of torque. What was most impressive, is that this is @ 15psi since I am getting some boost leak and boost fluctuation and some odd stuff going on with my tune. Car is Stage 2+, and for those who aren't aware of the S4 designations, this means it has an aggressive chip, downpipes, exhaust, and some other bolt on goodies. Our methanol injection played a huge role in our good numbers, as we did some pulls without the meth and for my buddy, it was worth a 35whp difference on his larger turbos.
He is full Stage 3 with K04s, 2.5" downpipes, and a dual 2.25" exhaust. He put down an extremely impressive 408whp and 416ft/lbs of torque. Again, for those not familiar with the S4, 400whp is very difficult to berak with K04's. He was running 23psi. We've seen a lot of other S4's dyno on this dyno, and a good running car without meth generally puts down about 350whp.
So... both of us beat our estimates by over 25whp, so needless to say, we are happy. After my next dyno in a couple weeks, I am doing full Stage 3 and am positive i can make it into the 400whp range, since I have some extra goodies like ported exhaust manifolds, 4" exhaust, etc...
Too bad my camera doesn't have a great mic; the sound of my car literally was overcoming the mic. We had to cover our ears.
Only got one dyno graph right now, this one was a bit lower then my best run
