Let me know if anyone on here has a 2.7 pulley that will fit the gm 4 bolt pattern for sale.

 

Really? 10 views and no replys. I guess i'm not in the "In Club" on this site!

 

Smoothflow Pulleys

 

lol chill out dude. the smallest pulley you can run on a 4 bolt hub is a 2.7. 2.6 won't fit

 

I have a 4 bolt ZZP 2.8" if you're interested. $30 shipped within the US

 

Yeah, I asked if anyone had one or where i could get one from too. Do you know where I could get a 2.7?

thanks evilution, but I have a 2.8 already on my car now.

 

see post #3....

On a GM 4-bolt hub....

Smoothflow's 4-bolt hub will fit down to a 2.5" pulley.

 

2.5" or GTFO

 

lol! Just so I'm not mistaken, I'd have to change my hub to a smooth flow 4 bolt hub to go below a 2.7 right? Where can i find the 2.7 that bolts up to the gm stage 2 hub?

 

Smoothflow 2.7" pulleys are the smallest that will fit the GMS2 4-bolt hub.

 

I just went on their site and selected "custom pulley." I typed the size of 2.6, and it seemed like they could make it. It was on their Stage 2 type pulleys selection. Are you sure?

 

Nate can make you any size pulley....

When you get into the 2.6 range it is hit or miss for needing to machine down the blower snout. If you don't want to get into that, purchase a 2.7. Like I mentioned before, a 2.7 is the smallest pulley that will fit on the GMS2 hub. You can get a smaller pulley with a different hub, but a 2.6 and below usually requires the snout to be machined to accept the inside diameter of the pulley.

 

Thanks for the clarification man! What are your mods?

 

No prob.

H62, GMR S3, Intake, Full Exhaust, Cooling

 

nice! Have you tried the High Octane Mode yet? What size pulley are you running?

 

Yep, I have.

I run race gas quite often. I have a 5 gallon gas can of Sunoco 260GT100 (CAM2) in my garage at all times

I run the standard GMR Stage 3 (2.992") pulley.

 

did u take your car to gm for them to install stage 3? who did the cooling mods?

 

Nope.

Everything done to my car was installed by me.

 

ever get a time on it?

 

1/4 mile? Nah....

Power wise it makes 270whp on 93 octane & 280whp on race gas.

 

how the f*ck?? just with a gm stage 3 and exhaust? i saw that u had intake listed on your mods. what did you do to it?

 

I don't run an M62 blower.

I think you missed that in my mod list. I have an H62. It is a prototype blower they made back in the day for the Time Attack Cobalt SS/SC. I own #1 of the 7 that were made. It has higher twist rotors than the M62, flows more air, and makes more power.



My M62 top & my H62 bottom:

 

H62? What is that?

 

I just explained it in my last post.

 

ok. that explains everything!
