Stillen Supercharger reliabiity

Chuck33079

I don't have a supercharger, but reliability is a function of the tune. Stillen kits seem to need a custom tune to really shine. Tell your tuner to err on the side of reliability rather than peak power. Leave it a little richer. Maybe a little less timing. Then it's on you to keep up on all maintenance. If you do all of that you can expect near factory levels of reliability.

Thanks Chuck. That is good info. Stillen says we can get 480-520- BHP. I think I would be well satisfied with 480 - so if that will make the car more reliable that is what I will aim for.

FYI, that is crank horsepower.

I am not well educated on this but my understanding is that BHP (or Brake horsepower) is equivalent to crank horsepower - i.e., substantially higher "numbers" than wheel horsepower - but not representing real world horsepower due to drive train losses between the crank and the tire/street interface.

That's alot of power, my STS kit put down 445 or something like that to the wheels and it's wild. Also, reliability all depends on the tune
