I'd say somewhere near 50hp...that is with the proper ECU tune though.

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

25-30 to the wheel with the pulley. 5-10 at most at crank from splitter and filter.

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

I have those mods but with K&N filters I stock Dyno'd at 286 RWHP and 316 RWHP after, look at the torque though it's a monster. Look at my sig and compare. The ASP pulley is only 172mm if you want more power get a 181 or 185 mm pulley. I am officially in the 12 second club.

wait, only 320rwhp after the pulley and ecu, but 300rwhp already with colder plugs seems odd to me.

I used the same dynojet dyno since the beginning...if the first dyno with AMG Jerry is correct then my start was at 286 and not 299 but who knows...I am not freaked out by it I don't go by the numbers that website claim cause thats not for all C32 so I go by the actual test numbers and track results....I will test at AMG Jerryy's GRD dyna pack to see what difference it shows cause I went to a Mustang dyno and they never dynoed a C32 before and told me I had 265 rwhp....when I told them I handly beat a WS6 they were like duhhhhh.. 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..

Dyno's are just that, a TUNING aid. TOOOOO many people put faith in dyno numbers as absolute, which is not the case. Take your car to 3 different dynos, on 3 days of the same air, and guess what, you get 3 different numbers. MPH in the 1/4 is still one of THE best ways to figure out HP, IMHO.
By the way, my g-tech showed I picked up 28 HP with just the pulley upgrade Which, made me VERY happy

See yeah

Agree that dynos can vary quite a bit, but also you ran a 13.9 stock, not a 13.29. With air filters alone, you picked up 6/10ths and 4 MPH - which I think most would agree is a huge increase from just filters...

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...

dyno's never absolute. take it to jerry's dynapack place. dynapack's one of the best tuning dyno. IMO you should see similar to what I did on mine with pulley and ecu and y-splitter with exhaust.
