not worth it. i have dyno proof when i got my car dyno tuned. after it was all said and done... i netted 2rwhp... which doesn't equal their claimed 10hp achievement to the flywheel. only good for if you ran out of bolt-ons and have $200 to burn.

You might consider the March. It is currently available, cheaper, fluid dampened, and looks like a quality piece. I just got mine but have not installed it yet.

Is it worth getting without a cam?
I don't plan on doing a cam swap anytime soon or at all.

If you think your going to get the slp go with the powerbond from New Era. they have it on sale. i got it in 4 days and for like 189 that includes shipping. Its basicly the same thing as the slp.

Good looking out I appreciate that. I know its not going to be a huge gain but 2hp is low. It has to be more important than that because its less rotating mass on the crank snout.

Someone mentioned 2rwhp gain.....Just wondering how many pulls you did in a row? was it just one before and one after? Not sure of dynometers accuracy range, but i would imagine that the only way to make an accurate guess of what a pulley nets would be to take at least 3 pulls before and 3 after and average them. no matter what rwhp gain I hear, everyone seems to agree on almost a 1/10 reduction in the 1/4.

after i installed everything to make my car a bolt on car, i got a untune baseline, then tuned.. came out to 351rwhp and then after the pulley 353... so yes, a whooping 2rwhp.

I've changed a lot of different ones. ASP are junk for quality, a large amount are not centric,= have more belts issues. And crank bolt loosening issues. Soft alum hub so the removal threads are weaker, and if they do loosen up the soft hub ID gets worn. Witch is common after you remove them a few times. The only thing I can think thats better with the softer alum hub, it that gets damaged before your crank, but it its installed right to begin with thats never a issue.

SLP/powerbond are the same units (made in Australia). And better in every way. We have them on sale for $179.95 Its a no brainer
