I did a search looking for underdrive pulleys for our trucks and there was talk that ASP could custom make them for us. Has anyone else heard anything about this or have any info on pricing? Under their new products they list a Lightning blower crank pulley. I wonder if there is a way to get that to work with the regular 5.4 underdrive pulleys. Thanks.

 

I now have an ASP 4# lower crank pulley on my 2002. Boost is quick, and solid.

Great quality blower pulley. And relatively inexpensive.

We need a special crank pulley made. I for one have been longing for something like this to be built. I know there is some newfound hp in our accessories if we underdrive them.

This used to make for a solid 10 rwhp gain on Mustangs.

There was someone on this board that said they were working w/ a company to design some but that was almost a year ago now that I remember him posting that.
