Re: ASP vs Powerbond vs stock pullies compare-o

[SUX2BU]

So i ordered a Powerbond pulley for my truck because no one had an ASP in stock. I then found an ASP for a good price so i ordered it. Took pics of all three pulleys and weighed them.

Weight of pulleys advantage ASP.
ASP 7.8 lbs
Stock 10.6 lbs
Powerbond 12.2 lbs

Quality of pullies advantage Powerbond.
Stock is a cast two piece that is pretty good quality. the power bond seriously looks like it should cost twice as much as the ASP. It just looks far better from a quality stand point. Also the Powerbond has very high lips so the belt will not get thrown like some have experienced on an ASP pulley. It also has a notch for a key and some cool timing marks on it like old school pulleys BUT you have to have an aftermarket crank or have your stock crank keyed for this to be of any use. The ASP also has a light weight aluminum center section which makes it lighter but if you remove and install your pulley A LOT of times, the aluminum could wear out over time and not be as tight on the crank as when it was new.

Ease of install avantage ASP.
To install an asp pulley you just put it on and tighten the crank bolt. The Powerbond, like the stock pulley, needs a longer bolt to first get the pulley on the crank or i use the head of an old crank bolt and an air hammer to get it on about a 1/2" or so before threading the crank bolt.

Conclusion, it's a toss up on these pulleys. so whichever one you find for cheaper is the one i would go with.

I have a SLP pulley on my Trans Am and that thing is a pain in the ars to get installed, tighter then hell! There's been some question on the ASP as to it's relation with timing chain failure lately so buyer beware. It's on ls1tech if anyone wants to look into it.

What brand was Moze's that "lost" a part and slung itself into plural units?

That's an informative write up.

So is this the crank pulley? If so whipple told me if a put a smaller crank pulley i would see more boost. Are these pulleys smaller in diameter would do you think would i see more boost?

[CHEVROLADE]

not sure about whipple but magnuson you want a bigger crank pulley for more boost^^^ or smaller blower pulley.

and slp ftw

[GasGuzzler]

Nope. Smaller crank pulley turns the blower slower. Larger blower pulley does too. Larger crank pulley or smaller blower pulley turns blower faster hence the performance of a smaller crank pulley on a non-blown engine....turns all the other accessories slower for less drag.

Zach beat be to it.
