Maggie Question
Gentleman,
How much PSI is does the stock Maggie pulley produce? I will be running 11 to 1 comp, LT and a 228/588/114 camm with a conservative tune.
Will I have to get a 4 PSI pulley due to comp? I was told a rule of thumb figure 20 hp for every pound of boost. My car is currently 433rwhp/401 fptq
v/r

I'm running a stock pulley with 10.9 - 1 compression. With Stage II heads and long tubes. Cam is 224 575 114. Boost shows 5.6 psi. This is due to a better flowing heads etc.
I'm at 502 rwhp and 469 torque on a conservative tune. (was 407 rwhp NA)
Maggies work very well with higher compression. Nice that you have good power when not boosting and when you do hit it the power is instant.

Vegas Vette,
Can you post or send me some pictures of your hood. Thanks for all the information, I was told by my tuner the setup would work but it's always good to hear from the source.
