stick with stock pulley or upgrade to the electric unit. the electric will free up more HP then the pulley and have less negitive effects such as a car runing hot. good thing you asked........take the money you would use for that and save a little more. Our cars run to warm already in stop and go, dont make it worse.
you might pick up a pony or 2 at the most on the highend from that pulley
the electric claims to free up to 10

I ran a WP and ALT pulley together. Combined they cost less then an electric WP. Reved up a tad bit faster and I didnt see any ill effects when it came to heat. If you have a DHP and Tstat, you wont get too hot anyways unless you have the air on in the summer.

I forgot you have a l36. l67s run a little hotter. if fish says it worked, go for it most of your GT mods can be directed to him for some solid answers. i would just make sure to do a complete cooling system inspection before i would slowdown my WP.

can i ask why you have a valvecover breather?



zzp fuel filter

:lolsign: ,sorry i just love this product.

I have a stage II or III TB from ZZP whatever there top one was. I would think about letting that go. Not sure if gt's need it though. You guys might get more air then you really need anyhow. Never liked working on gt's so never learned about them.

You can get L67 TBs to fit the GT UIM. Have to epoxy the holes closed.

Ok let me grab it out from workbence tommorrow and see which one it is. Was supposed to be the stage II but let me double check that. Big price differance in the two. I'll put it under a new thread tommorrow so that its easy to find.
