Just had a perrin lightweight crank pulley installed. Whats people thoughts on these?? What exactly are these ment to do for the engine?
So i guess its normal that I feel a change in throttle responce?
Just seems like the rpms are rev hire. I dont know maybe just gota get use to it. hope this was a good choice in getting.
I installed my lightweight pulley a few months back and immediately noticed the difference. Better response, quicker revs. To me, it's the poor man's lightweight flywheel. Highly recommended!
You can't blame a compass for pointing north.

The LCP is a "poor man's lightweight flywheel." While you will get slightly better throttle response and theoretically more power, I am convinced that the effects on the butt-dyno are largely perceived by placebo. At the end of the day, a 3 pound reduction in the crank pulley is less than a 10% reduction in rotating mass. It does make difference, but less so than we "feel."
