I have the Comptec SC with stock pulley. I want to upgrade the to the 7lb pulley. Is this going to be too much for the engine. I dont want to blow it nor do I want to change the pistons to lower the compression.

We have a FI section now.

Moving to F.I. now.

Thanks for the move.

Youll be fine, just dyno it and turn up the FPR. Thats what Im running right now.

jdmdohcpower

Do I need new spring or anything inside the FPR? I think dyno tunning is out of the question becuase there is no one near me that does it. It is my everyday car and I dont want any issues that may effect reliability down the road. How long have you had the 7lb pulley?

revhi

The FPR can just be turned with a allen key, but you need a way to see you air/fuel. Maybe a wide band. I drove 2 hours to my dyno. Most people running higher boost also have a aftercooler. If done right, reliability is fine. Dosent sound like you have the right tuners around you to do this.

jdmdohcpower

I dont think so either. I would make the drive but will dont have the a/c so I have that on my list to. I have an air fuel guage. Do you think it can be street tuned. I can just adjust the fuel to make the gauge read the same as it does now?

revhi

No its not accurate enough at all. Get an aftercooler instead.

Don't run the 7 PSI pulley WITHOUT the AC.
