i replaced my crank pully with the rrm crank pulley , i think they have it for your gen lancer too , one thing i noticed was the rpms climb alot quicker with the pulley

 

Does RPM climb quick because car is accelerating quicker or is the engine just revving more for nothing?!

 

your using less power to spin the crank pulley because its lighter therefor your getting more use out of the power your car has , so you do accelerate quicker

when i compared the weight of the stock vs rrm it was pretty amazing the weight difference 1 vs 4 pounds

 

I have a question/concern. After installing my short ram, car is faster at lower speed but on highways it seem to have lost some power. For example, car seems to struggle going from 80MPH to 90MPH while before, as far as I think that wasn't the case. Did I do something wrong?
