My friend has a jackson racing superchager on his b16. For some odd reason when he turns the car on the motor revs up and dosen't stop, so we have to turn the car off to keep from the motor blowing. If we disconnect the throttle cable is does the same thing. Anyone ever have this problem or no how we can fix it.

 

Vacuum leak..check nuts from manifold to blower. It's definitely a vacuum leak though.

 

OK thanks I will def check that. Anymore thoughts

 

I had a jrsc b16 and it did the same thing. It would rev straight to 6500 and hold it right after you fired the car up. We chased it down to being loose bolts holding the blower section to the manifold. Don't fret though as it's happened before.

 

Huge vacuum leak. Blower/manifold is a good first place to check.

 

thanks alot fellas.

 

check tps. my sock ls did that once... i put a new t/b on and when i started it it went straight to 4500 rpm then i tapped the gas peddle and it went up to 7k and stayed there. just a thought.
