yeah guys i just installed my boost gauge and i'm only getting 3lbs max, i know i have headers and a high flow exhaust and a full 3 inch CAI but maybe this is to low. there are no vacuum leaks and the engine only has 20k miles. when i took the supercharger apart rotors and case was in great shape not even a scratch. just pulley down or is there something not right? i have a 5 speed with 3.23 gears
 


i tap it in a t right before the map sensor. and only check engine light i have is p0000.
 
maybe that code is because i deleted the egr without tuning. everything on the motor is in good working order.
 


like this but without the sc bypass solenoid

It does not affect fuel economy all that much. When I was supercharged my gas mileage didn't change at all. The m90 won't make boost at 1.5k to 2k rpms which is where stock gearing cruises at anyways.
 
i do a tank in 2 weeks. with my lt1 t56 car i would do it in a week if i was lucky. the main goal of this project was fuel economy and power only when needed. so far so good but lets see what the dyno says on the 25th.
 
i was looking at another thread and saw that a bone stock l32 gtp does 5lbs of boost. perhaps with my CAI, headers, and free flowing exhaust 3 lbs is ok? today i guned it in first it noticed it went up to 4 while the car hit the rev limiter. lets see what happens when i pulley down.
 


Stock pulley with all those mods? If thats how it is then I could see that. Throw a pulley on and watch for KR.
