I know I Know, pulley's don't do a whole lot - well on my car the ASP pulley was a miracle product.


Not to say that I didn't adjust my valves at the same time ( SDPC Vortec crate)

I already have everything in the sig, so this was my last bolt on ( Not first)

The car pulls and revs freely, seemed to free up about 30hp, but I know in reality the valve adj. and pulley combined could easily make the diff.


Now my SDPC hotcam vortec finally runs the way it should, the thing is very quick, the torque is phenominal- and yes I own an LS1 - now that it's tuned - I have to say the the SDPC vortec is most likely quicker, and with a six speed it would be faster.


Any how ASP get a major thumbs up! I hate gimic products, and this is no gimic.

Debating on whether to get em....Did you have to change the serp belt?

Yes, you have to get a shorter belt, the instructions tell you which one. cost like $22.00 or so. the install is pretty easy, really not many out there that are this simple install.
