Wich under drive pulleys do you guys recomend? I plan on doing this when I do my timing chain. I figure that I will be there do the most of the work any ways.

 

Personally, I am starting to like the aspracing.com. You can order singles to triples. I installed them on my camaro and dakota. Jetchip I got crapy service and they only sell the 2 pack(got them for my s10). My 2 cents, CHA CHING!!!

 

ASP....I've had my dual pulley set for 2.5 years now. Its a 15min install....and even used on Crank-n-Chrome on TNN

 

First off-- Summit sells the ASP pulleys the cheapest 've found

Part # ASP541800 -- single 25% underdrive crank pulley only. $38.39



Secondly, I would NOT recommend the crank & alt. pulley set. I have done Some testing with this set on my car and the 2 pulley set turns the altenator too slowly unless you are running at speed. At idle it will not spin fast enough and the gauge will read at a discharging rate.

Thirdly, I have a Powermaster 200 amp altenator that I installed the altenater powerpulley onto and fabbed it into the car. Even with this high output alt, I was still getting a discharge at idle with the lights on and the a/c running (can be common in Calif on summer nights). I yanked the power pulley of the alt. and am just using the crank pulley even with my 200 amp alt.

 

Cool! Thanks for your guy's input. I think I will go with ASP. I'm not worried about charging at idle speeds. I spend most of my time on the Highway above 1100 RPM. The crank and alt pulley provide a full charge at 1100 RPM so i'm not surprised that you saw a discharge when using both

 

Just remember, positve charge at 1100rpm's with nothing else turned on (headlights, radio, a/c, etc..)

 

I ve used Thunder Racing as my source for parts. And ASP pulley's for the pulleys. But thats just my input.
