only the crank pulley
WOW!! That’s huge! This season I switched to 9.2 lbs. per corner lighter wheels & tires and shaved a full tenth off my 60 foot.If you've ever done any wrist exercises using a broom stick rope and light weights, you can imagine the difference in weight a few pounds can make. My 14 GT has had all these mods lightweight wheels/driveshaft/pulleys/brake rotors they reduced my 60ft times by .4 which is huge.(2.2 to 1.8)
Actually, I already owned a set of MODA MD20 18x8 (now discontinued) that I bought from Tire Rack when the car was new and used for winter wheels. I wore out the winter tires just before COVID and since COVID caused a job change that completely changed my driving routine, I decided to put them into race mode.What wheels to you switch to. That's next on my hit parade.
Any more info on that pulley. I am pretty anxious for the results. I am still looking for reasonably priced light weight wheels if anyone has a link, or name. This thing still wont beat my mustang off the line.Update I requested to be the tester for the 2.7 pulley, the 3.5 pulley has been made and is ready for testing, 2.7 pulley is still about 2 weeks out
