You should throw a 15lb pulley on that D1 you have.
After I throw in my built 32V motor, I'm upgrading to a D1sc with the largest pulley I can go with.

You do understand that the "largest" pulley will give you the lowest air flow and boost right?

Why go with an F1? There are plenty of Mustangs Runing 9-10's with the P1sc.... My Max i want like 600whp. and the D1 Will get me there just fine...

I am going to be Running a 3.2" Pulley (Not sure what the Boost will be on my Motor) I know the 3.4" Pulley on a stock Motor is 14lbs. I would like to Trow a SMALL Pulley on it from the Get Go, But with out a GOOD intake Manifold, radiator, 8 Rib Conversion Kit im not going to...

Here is the sound people are talking about, (listen for the high pitch whine in the flyby)

usually the larger blowers are louder, and the harder you spin them the louder they are. Things like an exposed air filter make them louder as well..

I have a friend with a kb car... it does come on strong early, but it isn't night and day difference than a procharger setup.

My car makes 300rwhp at 3000rpms.. A centri car will make good power from about there up.. you're looking at you're "fun factor" improving from 1500ish to 3000rpms..

I think you have a better setup now... if you was trading to a 2.8H or something lol I'd say go for it.

Most centri cars will still blow the tires off from a 2nd gear roll, that's pretty darn fun imo
