i found the 2.75 for $100

 

Wow. I didn't know anyone made a pulley that small.

 

who makes it and what is the claimed psi level with that pulley?

 

paxton makes a 2.75 and vortech makes a 2.62

is the pulley for the novi 1000/1200 and the vortech the same?
2A036-262 used this model# and it shows up as vortech makes it.2.62
2H036-275 this model is paxton the 2.75

 

looking at the new sos link i would think the 2.75 would make 13psi

 

Wow...2.75...that's got to be tiny.

It looks like you have a FMIC so I assume your IATs are good. What spark plugs are you running? NGKs one step down from stock? If not, you'll want to. Made a big difference for me.

 

yeah bkr7e

 

Anyone find out why the psi #'s have been changed?

Also, how many people are running the 3.0 or 2.75 pulley on stock engine without a thicker headgasket?

 

s2sexy...you should goto the 8e plugs which are iridiums. I noticed issues at high rpm with my car when i was running the 7e plugs

 

We sell the pulleys by size, rather than pressure, as that depends on a number of variables. We include pressure estimates. If we get enough feedback from customers suggesting otherwise, we will adjust. I think one or two pullies were changed based on customer's suggestions.
