I was just wondering if anyone has used March's new underdrive crank pulley? How does it compare to ASP? How is it different from what is already available?

 

Don't know about the LS1 pulley but I have seen a couple sets on Mustangs. They had powder coating that was peaking off, showing rust and looked pretty bad. I would stick with ASP, they pay attention to quality control better than March.

 

I will let you know how it goes... I just ordered one from Thunder Racing and I should have it next month some time.

I figure if Thunder Racing is willing to carry this product, it's probably a good bet that it's at least decent and should compare well to the ASP.

 

Famous last words!

I asked about the March pullies a little over a month ago and no one had any info on them, but someone said they were having fitiment issues w/ the 1st batch.
