How much boost can i see wiht a 2.7 pulley and how much horsepwoer can I expect from it?

Just bought one, thanks

 

I'm guessing about 30 psi.

 

Easterisland, your bad to the bone LOL

No soup for you, Next please!

 

inches not feet

 

Assuming that small upper pulley wont slip (which it will)

A Stock Lower / 2.7" upper combo will spin the blower about the same speed as a 4# lower / stock upper combo will...

7.9 / 2.7 = 2.93:1 Ratio
8.5 / 2.93 = 2.90:1 Ratio

So, in a perfect world, you should get 3-4psi depending on weather/othermods/etc... But, that teensy little upper pulley will slip considerably more than just a 4# lower...

3-4 pounds really??

Awesome

BTW>. this ain't on a lightning.. its making 9psi now.

 

what do you guys usually pick up with the eaton and 3-4 more pounds..

You really can't compare it to anything out there for us.. vortch etc..

 

well since its not a lightning the results may vary depending on MAF/ upper intake/phlenum(sp?) and the effectivnes of your intercooler to cool the hotter air charger s from your heaton.
but a fairly good guess would be with 4 lbs + = 30hp and 40torque?

 

Nope it's on a fbody!..I reconize you from CZ28..I switched to the dark side and bought a L
