pulley question
what size pulleys; on a stock supercharger, will put me at 15 psi or just above? and, will it require 60+# injectors and a tune to make sure it doesnt blow up.
|
my setup./
|
3.0 and 42s
|
3.1 pulley and no injectors needed bigger injectors are needed for 3.0-2.8 (42 injectors) after that than 2.7-2.5 get 60's i'm running a 3.1 and getting 15 3.0" pulley should get you 15.5 or 16 if not something is wrong with your tune

Hitting a specific PSI will depend on where you are at from sea level. In NJ you should be fairly close to sea level so a 3.1" pulley would get you to 15 PSI. If you drop the pulley size you need to go to 42# injectors. Anything smaller than a 2.9" pulley and you should have 60# injectors.
