Posting this for a buddy, he's building an Iron 420 Inch stroker, (I think 8.5:1 CR) fully forged w/ Callies crank, Ported Dart 225's, custom blower cam, Fast 90/90, D1 Procharger, front mount intercooler, BS3 engine mgmt, Kooks 1-7/8" LT's into a custom true dual exhaust, going in a 94 T/A with a built T56 and Strange 12-bolt.

He's not on the net very much but wants to know what kind of power this setup will make at certain boost levels (low, high etc)

Sorry I don't know all the details. But thanks for your input.

low 9-10psi 680-730rwhp high 15-18psi depends on fuel and weather but I say 850rwhp+

I would think the D1 is a little small also. I would say with the F1 or F1c/r he could make over 1000rwhp! The D1 will only flow so much air then it will become a restriction.

Jake@EPP

Exactly, you will be hard pressed to make 16psi with that setup. With a 1" OD crank pulley we hit 16psi on a large headed 408 iron motor. 750rwhp was all she wrote too, the d1sc was obviously maxed and was making hot air. A F-series blower will do you the most good, a f1a or f1c will be the best effort for max power.

Thanks for the input guys, I will pass this info onto him.

Another thing to think about is the CR-raise it up a point at least-having that low means you have to spin the blower really hard and then you just end up with belt issues. Even though the D1 is small, with the right CR and cam it can make 800 rwhp.

Hey guys, bringing this back up from a while ago. My friend is now considering the lastest Accell engine management system I believe its called Gen 7 or 8 vs the BS3.

Any preference over the other for his setup and reasons why? Does the Accell system self learn?

He is having a shop do the build and tuning. So not sure if the shop has a preference.

Secondly, He was also wondering if the F1 Procharger unit would be a better option over the D1SC, and if an 8 rib pulley and belt would work for either of these head units without slippage.

Did you not read ANY of the thread? This question was answered SIX times already.

Bad *** car BTW

Sorry, yes I did. He already has the D1SC head unit and is just wondering if its worth it to sell and upgrade to the F1. Like what kind of power difference should he expect with this motor and the two different head units.

Sorry, I don't know all the details, it's not my motor and I am posting this for a friend.

750--800 RWHP is all the D1 can provide (for the most part). The proper F series blower will be enough to support 1000+ RWHP.

Thanks, any opinion on which engine management system to use??

BS3 seems to be the choice for the "big dogs" on here. If he uses the stock PCM then HPtuners with a 3 bar map will work.
