I dont know if its pointless or bad to have a lightened underdrive pulley in the srt. Well is it? I had pullies in previous cars but never in a turboed car, whats the difference? wouldnt it make the engine rev really fast and put to much stress on the turbo?

hi Jordan......i believe ive read underdrive pulleys are a waste of money for the gain they produce

 

Our cars have not responded well to underdrive pulley's. For some reason oil-pump failures are more common on cars with underdrive pulley's.

For the same money get a WGA and a MBC.

 

whats a MBC?

Perhaps the Underdrive pulley is acting as a harmonic balancer.

 

They are a waste of money for the SRT-4. I have learned that by watching other people's mistakes. Unless I am building strictly a race car I will not mess with the harmonic balance of a car.

 

According to Darrell ***, the drive pulley IS a harmonic balancer on our cars.

 

Do you have one?

 

An aftermarket underdrive pulley? No-Way. Seems to be a leading cause of oil-pump failures.

I'll keep my stock pulley/balancer. The 5 extra hp the underdrive pulley might free up is just not worth the risk.

 

I put one on my Z and honestly I can tell a small difference but it was definately not worth the pain of the installation. I will never get one on the SRT4 then.
