my buddy hade that exact setup with 8.5-1 comp and 16 psi and he made 640 rwhp and 600 tq it was pretty strong it ran a 11.9 and 128 and he is a bad driver it was a mid 10 car if he knew how to drive

should put down some mad numbers. Not sure, but 14 psi on a 383 is most likely pushing the D1 to its limits with ported heads and free flowing exhaust.

My buddy is running that combo. 383,A&A DS1C, meth inj, made 625rwhp/520rwtq at 12psi through a new Tranny Level V with a 2800 Converter. Car runs 10.1-10.2 in the 1/4 mile at 137mph. He just switched pullies and is making 15psi now. Shooting of a 9.9 or 9.8 1/4...

I think the D1sc is good for up to 800rwhp with the correct setup!

nice ride>>

All those guys only making 640rwhp on built blocks haven't touched a number that their cars are capeable of. Something tells me that they're running out of fuel because 750+ is possible with a D1SC on 91 octane with a built block.

600 rwhp would be nice. I need to kick this P1 to the curb.

Didn't EPP just crack 700 with a D1SC on a 346?

It really isn't hard to get over 700 rwhp with a 346 an an ATI ProCharger D-1SC. You need a good bottom end, decent flowing heads, a mild blower cam, 60lb fuel injectors, and a complete fuel system. On the F Body, adding a front mount intercooler keeps the inlet air temps down. The fuel system is the key here, as Drewstein hit on. We can see 550 to 600 rwhp with twin in tank pumps with stock fuel lines and stock fuel rails. Past 600 rwhp, plumbing in a return fuel system is the key to making big power, along with larger fuel rails. With the added fuel system, the 346 can really be made to run big numbers. Bob

My other buddy Steve(Peter Pan on corvetteforum) is making 742rwhp at 14psi at 6000rpm(where they stopped the dyno run). Probably would have made more, but he said that was enough and set the rev limiter to 6200rpm. DS1C on a forged 346 with hand ported LQ9 heads, 9.4/1 compression, small 224/228 114LSA cam in a 99 vette...

Nice!!!

Very true. I'm still gettin the bugs worked out of my car along with a blown head gasket and converter issues. The rwhp number is merely going to be dictated by the type of converter (auto)/ powertrain you have. I only made 540 at the tires and she went 9.90 @ 139 with a horrible 1.6x sixty foot. I am only pushing 12-16psi of boost on the D1. I plan on adding a 383stroker or a w2w 402 with bigger SC - dont know which one. I would suggest going with a larger SC than the D1 if your gonna run more cubes than a 346 - just my .02 Good Luck! Jay

Keep in mind when we make 700+ rwhp on our Mustang Chassis Dyno with it's eddy current, that this would be approx 750 rwhp on a Dynojet. That tells us just how easily it is to hit good hp numbers with just a 346 and an ATI ProCharger D-1SC. Bob

What kinda break in do you do before you dyno your engines!

I have a friend we built his vette up with a P1SC and so far we have dynoed 661 rwhp and waiting for him to go to the track.

Nice #'s for the P1SC! What pulley are you running?

Forged 347 with the reichard pushing 10 psi
