Thanks man.... Not mine anymore though. Sold it.

sweet car =)

Thats why I said in the thread I didnt think it was hooked up yet.... I just knew you had said something about getting one when me and Lee were talking....

I bought a zex kit but it hasnt come in yet

Actually if you look at CobraBobs website, youll see what pulley combos make for boost.... Or averages. Go to....

and then go to section 3.6.1 and youll see what your combo is making. A 2.93/4lb combo only makes about 15.3-15.5lbs of boost.... A 2.8/4lb is making right at 16lbs of boost.... I should know too since thats the combo I run. I dont see my car making anywhere near 19-20lbs of boost.

seems like you are the only one that understands what happen with the 2.93 swap and the 2.8 slipping

I changed to the 2.93 and little did i know the car was making a lot less power. After the first dyno pull with no changes the car put down 477 and i was 520s before. He leaned the car out since it was rich due to the larger pulley and added 1 degree timing. And no the car wasnt detuned. The 2.93 pulley not slipping made the difference. The 2.93 is making more boost because the 2.8 wasnt getting its full potential. The 2.8 should have made more like 19-20 pounds of boost which stegemier even has on their site for the stage 5. I'm happy with 2.93 numbers being more efficient for the blower. My boost stays the same to 6500 rpms. Boost never drops off. Whammmmmmmy ROUSH!

Gotcha.... I never went that low on the dyno so I dont know what its making then.... I started the dyno at 2500rpms.

as soon as i can get the graph on the computer i will. i'm making 200rwhp and 460rwtq at 2200 rpm

Yep I put it on earlier. I got a 78.5 8 rib on. That 6 rib was a 79. I actually have 1 100mm 2 90mm and the bottom idler is stock. My alt pulley is 3.5 I believe.

thats all i could get at the time. I got the 6 to be able to go on the mexico run. I bought a 8 rib today.
