I have a Vortech V2 supercharger kit. Im eventually going to get it tuned with a 3.6 inch pulley. For now i have a 3.9 inch pulley. Will I be able to bolt on the supercharger kit with this pulley and be ok without a tune? With stock injectors, fuel pump and stock ecu?

 

You'll be fine as long as you don't go into boost at all.

 

What would happen if i went into boost?

 

Your car would run very lean and possibly blow your motor. Get injectors, fuel pump, ecu and a tune or don't drive it. No other option with the higher boost pulley installed.

 

oh i forgot to mention i have an ap2. I thought 3.9inch is the stock pulley

 

AP1 stock is 5". AP2 is like 4.5" or something I believe. 3.9" is good for 11-12 psi.

 

Alright well that answered my questions, thanks alot man. Btw i saw the video of your car getting tuned at evans. Looks great

 

Thanks man!
