However, I did stumble onto RKsports' unit: http://www.rksport.com/main/part_det...mdid=2&catid=3
This one looks awfully similar to our drawings. Without having a 2.2L or 2.4L crank pulley in hand, I can't tell if the dimensions are the exact. Regardless, This unit has a larger diameter than stock, which we aren't too keen on manufacturing.
Again, maybe the 2.2/2.4L one may work..??? I just don't know for sure.

But a crank pulley is supposed to have some sort of dampner in it to relieve stress on the engine. Solid billet pulleys can cost horsepower, as was proven by Fluidyne, even from the stock unit. A good quality aftermarket dampner will allow more power output safely though.

Whats the weight reduction?
would we have to get a new belt.
they are all the same i looked today at my buddys ss/sc and mine they are identical soo this will work for the 2.2-2.4 or the 2.0 just thought id let the good ppl at jbp know

there is a underdrive pulley for the other motor but not the 2.0l supercharged motor...\/read
Ecotec Billet Crankshaft Pulley 88958631
"This billet crankshaft power pulley has a reduced diameter to minimize the horsepower robbing drag of the alternator and air conditioning compressor.
This crank pulley would NOT fit the 2.0L LSJ. The naturally aspirated ECOtec engines (L61 and LE5) have a 6-bolt crank, while the boosted ECOtec engines (LSJ and LNF) have an 8-bolt crank. The GMPP crank pulley is made for a 6-bolt crank. The purpose of the billet crank pulley is to withstand the rigors of racing applications that involve extended time on the rev limiter." from crateenginedepot .com

Yeah there's a diff between the L61 and LSJ crank on the other side, where the flywheel bolts up, but that has nothing to do with the front of the engine where the damper bolts up....

Alright folks, the price is in.. The set MSRP price is: $349CDN Thats the recommended price for our dealers to price around... (Typically they'll sell for less.)
We're offering our dealers an immediate incentive pricing for the inital product release. Which means, they'll be much much lower than the MSRP. Dealers, feel free to post your GBs on your websites repspectively!

thats the MSRP price. Dealers will sell for less. However, we are promoting this new piece with a huge discount offered to dealers, so the final price will more than likely be less than $300 depending on dealer pricing.

Just got the first two proto-types. They're going on two cars for testing. The units shown will be balanced first and the keyway for the crank broached. they are shown with a specific case-hardening for extra durability.
