I am not sure if there is a difference between them. Also what type of gains have you guys been getting? Thank you.

 

SLP here.....works with the DR chain, so i used it.....no problems, so i like it

 

its a toss up. they both make about the same gains and both are well put together so jsut flip a coin

 

slp/powerbond here

Beautiful piece of work!

 

I have the ASP. No problems so far. Makes a slight differance in power. I didnt Dyno mine before and after but most people say about 8hp. Just make sure to replace the bolt when you change the pulley.

 

I have a ASP. I pick up about a tenth at the track. No experience with the SLP.

 

how much does the pully cost?

 

225 For SLP and 245 for ASP. Plus shipping of course hahahah and if you buy directly from SLP you get the infamous "HANDLING CHARGE". Hahahahah.

 

You're going to get a deadlock on opinions, and there really isn't much difference, which is why it's a pretty even distribution of who has what.

After much research I decided on going with an ASP, only because I ordered my cam and everything else from the same place and that's what they sold. It works perfect and I've never had a problem with it. Took it off and reinstalled it once already with zero problems on either install.

 

Well if thats the case then I would be better off buying the SLP if they are identical. I wish someone would chime in and tell me what type of real world gains they have seen.

 

asp here
like it alot

 

Average is about 10rwhp with a 25% UD pulley.

 

ASP.. no problems

 

ASP...still not on the car but I got it used cheap.

 

Thanks for the info I apprecaite it.
