Vortech pulley problem.. I have a 2001 ws6 trans am with a vortech v-9 g-grim on it. it has the stock 6 lb pulley on it, i want to go to 8 lb.Vortech told me i have the only pulley that will go on it.. i was told that i have to purchase a different pulley then have it machined... or does anyone have a better fix to this or do they know or have a site that i can go to, to get this done... if you know a good machine shop that does this please let me know.... thanks josh
I have the Vortech pulley 2A038-295 on mine and had to machine 0.326" off the back in a lathe to make it work. I got those measurements from the engineer at Vortech. Its worked perfect and added roughly 2lbs more boost from the 3.12 stocker that came with my kit.

Verdad Gallardo Yes, 2A038-295 is the Vortech part # and I bought mine off ebay. It is an 8 rib pulley and 2.95 is the diameter. Im assuming all Vortech kits had the 8 rib setup but not sure. You will want a slightly smaller belt than the stocker, maybe 1/2 in or so. If not, when you stab it both sides of the belt will barely touch from streching and the belt tensioner forcing them together. I have used Gates belts for 30k miles on this setup with no problems.

Why not post a picture of your pulley with some dimensions, and they people can see exactly what you need, or need done.
If you just need an off the shelf pulley adjusted in a lathe, it should be a very easy task
But ASP as suggested can make any pulley you'd ever need. ( Auto Specialties Performance ) https://www.autospecialties.com/
Or try contact ECS or A&A Corvette, I'm sure they will know pretty much anything there is to know.

Thanks, I appreciate it. I don't do any custom head unit pulleys. To the op, I've pulled several more psi out of ProChargers by going to a larger air filter, you might try doing that if you haven't. I wouldn't spin the blower any faster than you are until you first know what the impeller speed rating is, and find out what rpm you are currently at. Bob

Any Vortech pulley will work. All you need to do is mill .370"off the back of the pulley and you will be set.
If you go below 2.95" I usually reposition the tensioner. Also the G Trim impeller doesn't like to be over spun. I have seen countless impeller fractures.

0.326 or 0.370 off the back of the pulley?
I believe i bought this pulley off of you.
I dont know about all the custom pullies you guys are referring to but the Vortech pullies are about $70 or so and cutting them down is cheap. I turned 0.326 off mine in a lathe and the same belt has been on my car for 20,000 miles. I'd say that works pretty well...
