Sorry guys havent been on the board in awhile.

The ASP pulley as i said before replaces the original pulley. It still has some good weight to it (not light like the aluminum bolt ons), however i would guess it is at least 4lbs lighter than the stock damper. The reduction in rotating mass alone is worth the buy IMO.

Thanks for the links!

OK, now I have a couple questions:

1) What is the difference between the kits? There are "add-on" pulleys with 34% crank and 15% alternator stating full charge at 850 RPM.....I assume this means full alternator charging capabilty.

2) Then there is the 23% reduction harmonic balancer and 15% alternator setup (costs more, why?). What are the differences between these two setups?

3) It appears that you get a better alternator charge at a lower RPM using just the crank pulley without the alternator pulley....am I right? Why would I want to use the alternator pulley?

OK, help! I am just wanting to be sure to get what is best for my LT1...thanks everyone!

 

whats the diff between teh regular, cheap, crank pully and the harmonic balancer crank pulley which is about 100 bucks more?

 

ok, just to throw in my .02...difference is a difference, no matter how small. I'm not saying you'll gain a .01 of sec on your 1/4 run but I though hp freaks are all about some gain no matter how small Whether it's worth the time or money is really up to the person buying it.
