Any one use it? I just ordered it. Also I went to a k109594 rpm belt from a k100582 rpm belt. One and a quarter inches longer. I have a 10 percent overdrive on the bottom and a 2.50 upper making about 1k to the rear. With the intake spacers the 100582 was too tight by about a half an inch. The belt is starting to fray.

I do not use RPM belts. They don't have the "gjve" that the green or regular black have and instead of stretching they tend to fray or outright snap.

That said I do have the 3.5 idler on a bwoody with a 2.79 for daily and a 2.50 for track. I keep same belt for both sizes and all the 3.5 did was go from dead nuts middle to a smidge tighter. Not worth switching belts over once they wear in.

Karma. I accidently received the wrong order. The green belt. I will have the 3.5 idler pulley in a couple of days. Should I use the green belt?

If the belt is the right size there is no reason not to IMO...or keep it for a spare. Either way.

Got the car back with the 3.5 idler pulley. The marker lines up right in the middle. I took the car on the freeway. Boost in the upper rpms is no longer going down to 14-15. Staying at 19-20 at a da of 6-7k. I did the green belt. Good mod.
