how much power on c32 will following mods
C32used had tested the efficiency of a few aftermarket filters and came up with an answer for filter performances.
This is what I got from ASP on their pulley
Approx horsepower and torque increase? 20 hp to the wheels. (Expect 18% drive train loss for auto and 16% for manuel)
I have no idea on the performance of the SL55 splitter.
I think somewhere +/- 30hp to the crank if I estimated it right.
With a ECU tune, you might gain another +/- 15hp to the crank.
I agree to rlee02135

i never stock dynoed my car, but with ecu, pulley, splitter, and the filter I was at 353rwhp. around 16% loss since i was on dynapack I'm probably at around 410-420 crank. Even IF my car is one of the stronger 32 at the usual 290-295 ish rwhp that's still 60rwhp gain from these stuff.
I had 312 rwhp and 314 rwtq with that and Magnecor wires. I was stock with dirty K&N filters 286 rwhp but with Fresh Green filters on a colder day I was 299 rwhp 290 rwtq....so its a possible gain at the rear wheel of 26 hp/tq...not spactaculor but it did wake car...I will be officially in the 12 club in the Spring

so I stopped taking dynos for the numbers and just use them for increase or decrease of a mod...if I had 265rwhp then my 13.29 when stock pass is incredible right..

By the way, my g-tech showed I picked up 28 HP with just the pulley upgrade
Which, made me VERY happy
See yeah

13.29 was the best with aftermarket airfilters while I ran stock...13.9 was best with stock air filter...Jacek ran a better 13.2 then me with stock air filters...so there is a chance that the stock airfilter could have done better but it was easier with just the change of filters. I understood what you meant now but the track is a better indicator of hp increase no matter what the mod...
