Simulation experts chime in!!!
I want to know how much faster will my car (E90 2011 DCT M3) be at the ½ mile if I go with a stage 1 SC (550HP). My car has the following performance mods:
Akrapovic Evolution Exhaust Dinan underdrive pulley AA Green filter ESS Akra Evo tune V2 Dynoed (on 30K miles spark plugs) 377rwhp (STD) At the ½ mile trapped at around 138-139mph (suboptimal traction at the starting line I might add, this will be addressed later) I know there are many variables to consider but just wanted to have an idea of what trap speed to expect (if its possible through simulation) if I upgrade to a 550 kit. Thanks in advance.

Thanks man, but I don't have any files. Just a mediocre graph with HP and AFR. No even torque graph or RPM's. The guy did not seem to be very knowledgeable. Honestly, I wouldn't make that much of it but that's what I have available where I live. I did the dyno because I wanted to at least know "something" about my car's power.
Thanks again.

I think you can expect to gain about 13 mph in the 1/2 mi trap.
Shown below is a simulation comparing speed vs. distance for a stock DCT M3 and one with 380 ft lb, 550 hp crank. Losses are 11-12% (don't recall exactly). When reading the chart precisely with a cursor I show 140 mph for stock and 153 modded with the AA kit. Thus it doesn't appear you had really major traction problems with the stock car. You don't need a dyno curve for this level of estimate. I think 150-155 mph is a pretty confident range, given 550 crank hp and the losses I'm using (which have been validated with a wide variety of other test vs. simulation comparisons). That is a gain of 11-17 mph.

CarTest is only $40. It takes some learning, patience and exploration and as I have mentioned in other places, garbage in = garbage out. For folks who really want fast answers to these type of questions please support this small software producer.
