Which pulley did you decide on Norm?

[norm8332]

I went with a 3.0". Some people might want the others. I know some go with the 3.1". And all of these will also fit the GTO 112h and 122 Magnachargers.

Does anyone have any idea on how the 3.1" pulley would work with a 100% stock setup? I am wondering how bad back pressure would be through stock exhaust.

At around 3.0, I needed to upgrade the fuel system with a pump booster due to the extreme fluctuation in fuel pressure.

At 3.1 I would probably do the same thing and fuel injectors.

I think you may get away with running a 3.2 with the stock injectors. They would be maxed though. I got a noticeable power increase going from the stock 3.3" to the 3.2". I ran a 3.0" pulley with the stock exhaust and it peaked at 11psi @ 6500. Thats a bit high. I never tried the 3.1".
