42% Underdrive pulley
I purchased a 42% underdrive pulley from rpmoultet.com. i read in a forum the 42% is best for the v6 mustang and provides horsepower without any risk of losing a lot of watts.
After i received my pulley i found out that the 42% pulley was the only pulley that they did NOT test. I was extremely worried about this. I kinda figured that RPMOUTLET priced this pulley in the range of the rest of the pulleys to make it seem like your getting a better product for a better deal.
Has anyone purchased this pulley and have any success or failures, I do not want any strain to my car caused by this pulley in order to get more horsepower, to me thats not worth it.
