My Dyno numbers for all my mods....

I'm just supplying the info. Dyno's 1, 3, 4, 5 were done at the same facility and same dyno, so the 37hp total gain is accurate. The only gains that can't be 100% comparable are the 7hp gain from the Stillen cat-back, and the 14 hp gain from the HFC's and headers. If you eliminate the dyno performed on a different machine, you still get a 25HP gain from cat-back, headers, and HFC's, and then of course the 5hp from the pulley, and 7hp from JWT pop-chargers. Overall, the total 37hp gain, the pulley gain, the JWT gain, and the cat-back, headers, HFC (together) gain's are all accurate and comparable. I hope this info helps others thinking of modding, as it cost me the same amount for these dyno's as it did for the pulley AND intake!!! 
well... almost as much

let's see here...
1,100 for Stillen cat back ( i think, can't quite remember)
550 Berk HFCs
500 Stillen headers
300 JWT
210 pulley
so about 2,660 for parts.
labor was 150 for pulley, i did the intakes, 440 for headers, and 260 for hfc's/cat-back.
Total for everything was about $3,510, as far as performance mods that is....
rims were like 2500, tint was 200, brakes were 1700 etc.. the list goes on and on

AZ, thanks for all the time, effort and expense. I never doubted the pulley would provide gains. From what I understand it may even go a little higher. But on another aspect, where are you getting your CB interior?

Even the VQ guru would back me up if he knew that the only dyno performed on a different machine was my 2nd. The full exhaust dyno, the pulley dyno, and the JWT dyno were all done on the same dyno so the numbers are legit gains. There is no magic here neverbonestock. I went to a different shop for my 2nd dyno because they had a special that day, all the rest were performed on the same dyno, same location. I suppose that you will argue humidity/temperature/ dew point gave me my gains now???
