Hey Guys, I found out that I am running on 2.8 pulley for an Year! I bought Stage 2 Kits from OTTPerformance. Their Website said 3.0 pulley, but I got pulley they mark it down 2.9 pulley. I emailed them n said they gave me 2.9. Josh email me back n said it is 2.95 pulley. I believed him but I was running my 42# Fuel Injectors that time. Good thing I switch out my fuel injectors to 50#. Anyways, I bought Smoothflow pulley 2.85 about week ago n got it today. I was excited n want to see how small it is. But I was wrong n confused, I said "WTF!" My Pulley on my Supercharger is alittle SMALLER than 2.85 pulley that I have BRAND NEW! I guess I will either sell it here or take it back. I just can't believe that Josh would lie about the pulley. I could had go BOOM! But didn't n I change things around REALLY QUICKLY! Now I know what I got. I am gonna port my DAMN SUPERCHARGER!

 

Dont the pully have a number on it mine from zzp does im assuming ottp would do the same.

 

I don't know yet but I will find out soon.

 

Ottp uses smooth flow pulleys

and a 2.8 is ok on 42s i did it for along time

 

Yeah, But You can't go past 5500 RPM. You will be risking 42# to be fried.

 

I reved to 7500 with a 50 shot..

It's not the smartest thing to do. But it does work

 

LMAO! You're CRAZY man!

 

My 2.9 made my injectors go static at 5500. Had to upgrade to 60s

 

I'm running 60s on e85 on a 2.8 pulley

 

I wish that I have E85 around in my location but I don't. There is 1 but an hour away.

 

To the people that claim a 2.8 on 42s is ok my gm stg 2 pulley on 42s has my idc at 102% just saying....

 

Gm stage 3 is the same injectors

 

Why did you just believe the guy, i would have measured it myself if it was unmarked. I dont think you can say he "lied" about the size, maybe he was told it was a 3.0, or a 2.95 for all you know

 

He mark down on the plastic bag stating "2.9" that Pulley with. I didn't realized it n didn't look back inside of Pulley that Vander Nars just said. I will find that out when the weather gets warmer. How can OTTP get told if they are 2 men business n Nate from Smoothflow wouldn't do this.

 

Smoothflow pullies are marked on the inside

 

Oh I know that since Vander said that. I said OTTP used plastic bag n mark down "2.9" with Pulley is inside of plastic bag.

 

Smoothflow = best pulley!

Sucks about the misinformation.

 

Lol

 

Smoothflow marks the size on the inside of the pulley.

U could have found this out yourself man....

 

I didn't know about this, I bought my 06 Cobalt SS SC 1 1/2 years ago. I bought stage kits 1 month after I bought my car then ever since I had been researching here around this forums. Vander just told me here that I never knew about but now I know. It's ALL GOOD!
