Please explain pulleys to me I was on Thunder racing's website and saw that there is an underdrive pulley and also a super dampner. What is the difference between these two, do i need both, and is an underdrive pully hard to install? for 300$ 8-10 HP doesnt seem that bad, thanks!

the u/d pulley is a very easy install,atleast mine was. i got the asp one with the alt pulley also.i just got rented a puller made for a chrysler i believe and in about 5 minutes it was off.i then heated the asp one to 150 *and put it on using the stock bolt since i had quite a few threads to use and it was going on easily or otherwise i would have used a longer bolt.

SLP also has their underdrive pulley which you won't need an aftermarket tensioner for. That's the one that I wanna get.

No they do not need a new tensioner. Mine has 121k miles on it and it's never let the belt fly off my ASP. If you get a pulley and have problems, it's either not seated all the way or your tensioner is less than stellar.
I ordered my ASP and belts from Futral.

The ATI super dampner are serious insurance for a serious engine. Most of the time these are overkill for street cars but that all depends on whom you talk to. The ATI is not a fluid filled unit like the march. The ATI is a rebuildable balancer that has a combination of orings and counter weights designed to absorb most of the harmonics that the reciprocating assembly may give off. Most engines that are at high RPM for an extended period of time such as a cup motors generally use these types of balancers.
Most of the customers I speak with are running the ASP or Powerbond/SLP.

So is there any difference between the ASP and the SLP Pulley?? Or are they the same thing? I also read that you shouldnt get one if you are just driving your car for street use / daily driving, they said you should really only get one if you are going to use it for track use? This is what I dont understand. Any help.

I'm tempted to pickup the ASP pulley and speed inc tensioner from speedinc.com
Any input of it this is worth the 330 or so bucks?
Would there be a noticeable difference with this and a ported tb?

both the asp and powerbond/slp are excellant parts I would recomend either to anyone. There shouldnt be any horsepower difference between the two.
I guess it depends on aesthetics
ASP - Black finish
Powerbond/SLP - Shinny
