I'm looking to buy the Unorthodox racing pulleys but I just want to hear some reviews about them, do you need to retune after installation? Anything will help thank you!
I bought the Unorthdox crank pulley for my 8th Gen (not under drive - just lightweight) and it helped rev on demand. Was running F.P. and lightweight flywheel. Was told that a crank pulley without a dampener was bad from the race crowd. Same folks with turbo's and S/C's. Meh, if it added, it didn't hurt mine for 100k+ miles. Died at 310k due to sudden stop. Engine still ran. Gauge for yourself.I have the Buddy Club pulley set that underdrives both the Crank and Alternator pulley. It's all relative but I "think" the car accelerates more efficiently.
No tune needed.
