im confused on whats a safe pulley size to drop down to, im gonna be using a paxxton a/a blow thru and my tuner is fabbing up the piping with minimal bends and everything welded. The best i ran so far is a 12.4 at 114.41 so my car is making good power i just hate how the car feels when the iat temps go up and it pulls timing. I'd be happy making a bit more power nothing crazy, safety is the key so the most i'll drop down is a 3.4 or 3.48.
go ahead and get a 3.3 pulley or even at 3.25 ...... 3.4 might not be enough to make up the difference ......
i lost 30 HP when i put my first IC on. i dropped from a 3.5 to a 3.4 and added a power pipe and still lost 2#.
my new one iis a better setup and i have a 3.25 pulley on it now. i'm currently making the same power i did before either IC. (375 hp)
at least the inlet twemps are down 100* from whatthey were
but I pulley'd down more to a 3.12" recently and it has the boost back and a bit more pep in its step also!
Same here. I see about 10 lbs at 5500 rpm. I'm sure I'll hit 12 if I goto 6000
You won't make 2psi in 500RPM, that sucker (blower) ain't that efficient
Dang, is that on a mustang dyno or something??My car put down like 423 with just exhaust, intake, and vortech w/ 3.33" pulley
