Overall I am pleased with my pulleys that i got from larry at Imprezars.com. The engine spools up faster and it seems to improved torque throught the power band but especially at low end range. you can keep it in second when going around a corner at super low speeds as long as the rpms are above 1000 or more it doesnt bog down.
PS. I also have a cold air intake exhaust with midpipe and headers, and the pulleys were the last mod that ive done so im not sure how just the pulleys would perform by themselves.
