How much boost are you getting from your Greddy Supercharger? I am getting abou 5 - 51/2 with an underdrive pulley. I have a new pulley on order.

 

theres a guy on the 14.2 xb thread that has the greddy supercharger with a custom 12.5psi pulley.

 

Wow that questions sounds familiar Rocket, LoL, but i second his question, the person who get it right gets a cookie, HAHA. (J/K) I'll be watching for answers also. I thought greddy said it would run 8 psi in boost. What do i know thou...

 

the greddy kit should be around 7psi. it has more psi than blitz and power enterprise, and has a 129.9whp dyno result on the 1.5l bB's.

 

Hey I have a greddy sc... I was boostin at 5 but then I found a kink in the hose... So I replace it... Now I boosting 7... I using autometer boost gauge... I think its ultra light.. The silver face and bezel

 

Thanks! Would love to hear from other S/C owners...

 

Hey what brand of gauge you using?

 

I have an Autometer.

 

that's not bad
