I just thought you guys may want to know what it did on my car .

I dynoed it before and I was at : 239.83 RWHP and 283.04 Ft-Lbs Torque SAE numbers on a Dynojet so I left the car strapped on the dyno , removed my stock throttle body and plenum put the 70mm Accufab kit , bolted everything back together ( about 45 minutes ) and dyno the car back .

I went to 245.22 RWHP and 287.09 Ft-Lbs torque , I made sure the engine temperature was the same ( around 165 degrees ) .

I gained at the rear wheel , 5.39 RWHP and 4.09 Ft-Lbs torque .

This is not a magazine test it's a test from my own sponsor ( my wallet ) .

I'm sure this set up will be very good for a supercharged car but it's kind of good for a N/A set up .

I did not have any Nitrous in my tank to try in so I have no NOS numbers .

Install was very straight foward , like I said earlier it took me maximun 45 minutes by myself . I did not take any pics of the install but I have some after it was done .

Here they are .

I had the wide band meter hooked up where the factory O2 Sensor plugs are and it was around 12 something ( the meter was hooked on my rear view mirror, so it was right in front of me but I was paying more attention at my RPM ) but I don't know if the Dyno computer saved a data of it , I'll ask tomorrow . :shrug:

did you reset the ecu for this mod? I know it is suggested in the instructions. It does seem to take quite a few miles after resetting for the computer to relearn everything, so it's understandable if you didn't at the dyno. Just wondering if the gains are the same if you don't reset the ECU vs. if you did.

No I did not , the stock TB was taking off and the new one put back on and redynoed !

I'll redyno the car next week after driving it all week end , I don't think it will change something but we'll see ! :)
