I'LL BUY EM!!Eric Brooks said:No help is my vote. But thats purely based on my setup. My car with a 2.93 does not slip, no belt dust.
I have an idler if anyone is interested in buying it. I bought it at the same time that I bought the pulley, and was going to put it on, only if I needed it, but so far I haven't seen a need for it.
Maybe a 2.80 pulley car needs an idler.
I have also read a few threads where guys removed their idler and ran faster.
