Ok, im building a 383 for my Sonoma GT project, im using a 5.3 block bored to 3.905 with a 4in stroke callies crank and rods, im going to be running E85 exclusively. Looking to run around 9.5 to 10 to 1 CR, id like to run somewhere around 15 psi boost, and don't really have a HP goal in mind, as im sure the numbers will be pretty high. Its all running thru a built T56 and Mopar 8 3/4 rear end with 4.10 gears.

The reason i want the 15psi number is because the factory boost on the Sy/Ty was 15, and even though the Sonoma GT's weren't FI from the factory, id like to run the same amount of boost.

I'm looking at running the TFS 215 CC heads that are fully CNC ported with 64cc chambers. Max RPM is probably going to be around 7K or so, and im not sure what the cam specs will be at this point.

So my main question is which blower would be better suited for what i want, and im already planning on running the cog belt setup so i don't have any belt slippage problems, plus it looks bad ***.

Thanks for the feedback.

I'd run the 2300, so you don't have to spin it as fast.

Well I ha no idea why you are hung up on the boost number? With that being said you will want the 2300 because with that engine you will be in the 900hp range with efficient boost. You will be using every bit of that blower.

yeah i was thinking the 2300 was the better choice, just wanted to see if anybody thought the smaller 1900 would work better.
