i just got my stage 2 and now i wanna get the 2.9 pulley who has good pulleys?

 

Someone makes a 2.9 or 2.85 that is engraved and looks exactly like the stage II pully

 

there is a guy on here that makes the pulleys, i cant remember the name though....

He is on these boards, his name is nherbst454 on here. I've heard good things

 

anything under the GM Stage 2 pulley (3.01) is unsafe. I've seen a guy hit 115% duty on his 42lb injectors with a 2.9". The injectors and tune are simply not made for a smaller pulley. If you want the boost, get the supporting mods (60lb injectors and custom tune).

 

That's the guy that made my pulley. Good quality and bolts right on to the GM hub.

 

Are you sure? I've heard alot of people who have been able to run the stg3 (3.0) or 2.9" pulley without problems. If there is a problem, I really want to know so I can stop saying that a 2.9 would most likely be safe.
And I thought the gm stage 2 pulley was ~3.1"?

 

Stage 2 pulley is 77.9 MM.
77.9 MM = 3.067"

 

nherbst454 made mine, Awesome piece of equipement. He makes all sizes and for all the different types of hub. Get the polish, it looks alot better than just black!!

 

There has been fight after fight about the 2.8" pulley being unsafe for the 42 lb. injectors. The 2.9" pulley is perfectly fine. I'm not going to argue about it. Later...

 

And about the duty cycle of the 2.9, maybe it happend once or so that the duty cycle where over with the 2.9, but generaly speaking they are safe. 2.85 is pushing it, and 2.8 IMO is not safe. But hey I like to keep things 99% safe. Run the 2.9 and dont worry about it, or just get a 2.95, or 3.0 if you arent comfortable with 2.9

 

well if you guys want I can post some screen shots from HPT running a 2.9" pulley.
Anything over 85% duty is unsafe!! If I go to the track and want to make 10 runs in the hot summer weather, I want to be damn sure my injectors aren't gonna crap out and blow my engine.

Basically if your going to run more boost, you need to get supporting injectors and a proper tune, man it's only like $400.
