I found this looking for upgrades for my recently graduated son's 2006 Cobalt SS...

What do you think?

 

Whoa, does this actually work??

 

I don't know, but maybe Grippy or BlownChevy will chime in.
I just thought that it was a pretty interesting find...

 

I've read that it's a pretty high quality piece. I haven't seen one myself. I've considered getting it since I want a smaller pulley and it's not that much more expensive than just a pulley.

I'm sure some of the usual suspects (MOD junkies) will chime in pretty soon!

 

Waste of money IMO. When you find your boost and tune that fits you, why have it,... are you going to swap pulleys on a daily basis?. It would be great for a shop/tuner that swaps pulleys all the time dialing in the best tune possible on each level.

I would just buy the pulley you want and tune for it. Just my opinion...

 

that guy is a dip **** anyhow.....so if I put a 2.8 on my 6.0 I will get 5 more psi?

 

Saw this about a year ago, possibly from one of the "imitators". To be honest, I have changed my pulley back and forth a couple times and it only takes me about 10 minutes, so I don't see any time savings. It really isn't that hard once you get the routine down. Plus, you can buy regular style pulleys for about $100, so there is no cost savings. In short, I really don't see the advantage.
