You may want to check your boost gauge ad make sure it is working correctly. A 3.6 pulley on a vortech is a 8 lb pulley.

now i have a eaton (roots) and it makes 446rwhp and 476rwtq at 13psi (the 4v helps the tq though)
and when i had a KB on my 2V it made about 30more rwtq than hp.....
Roots/twin screw will always have more tq than a centri in the same setup....which is why i will never buy another centri blower because it takes too long to get to the fun!!

lol, I have a T-trim not a s-trim. And I think I may know why my tq was down, because the PVC rubber hose where it vents back to the plenium was sucking flat. IT feels lke its puttting down over 400RWHp now and a hell of alot more TQ. I miight need to go back to the dyno. But its burning a little rich.

Well 4.10s will do the trick for low end tq. If you shift consistly at 6000 rpms like I did you will end up cracking a piston and needing a new motor especially at 12 psi. Those pistons were never designed to handle all that compression. I was at 10 PSI and she blew.

388RWHP and 346RWTQ, however since I fixed that hose like I said in the last post it feels alot stronger.

Well I glad u have a T-trim to.. But by my auto meter gauge I am pulling 12lbs at 6500rpms. I dont have an INtercooler, just the discharge pipe. And I know that a 3.60 pulley isnt the largest from vortech, call them and ask for ur self.. The blower only has 100 miles on it, so its almost brand new. If u try to spin the pulley when it wasnt on the car it was even hard to get it to go around 1 full time... Also my belt was real hard to get on. So then again I am still get 12lbs. and it acted like it wanted more. Man when my motor was stock with just an intake,UD's,stage 2 clutch and a Diablo tuner I was sucking a 6.0 litre GTO's up from 50 yards back. I have raced alot of mustang gts with bolt ons and gears same year through 04 and just smoked them. I bought the car this way.. Its got me curious if there was a mild head work or something done to it.
