I'm guessing around the 525-600 mark but all depends on what you all have in it and cam specs, cr, and etc...... Popo8 from LT1 forums did around 580-590 12 psi with 383 LT1. He has 225 AFR heads so he has the flow also. I'm do not know the flow numbers of the LSx heads but I know they flow damn good. Your cam is pretty good size also.

But I know its LSx vs LTx but gives you an idea. And I dont know the details of his build either. However Procharger says the PS1 is good for 875.....I dont believe that either. That would make my little 600b good for 775 I think they say and I flat out call BS on that...and if you do Its a 500 NA motor with max 62k rpm of the charger also And I'm spinning mine right at 52k now for 2-3 psi. For sure all out race fuel and or 85+ etho.

We need more info on the car. 6spd or Auto? Headders or stock exhaust? Decent P1SC combos break into the lower to mid 500's usually..there are a few north of that as well.

Why only run 8-9 psi? Adding 317 heads and meth injection I would run up to 13-15psi. The key is to find a very good tuner!

Mike Duke Ported 317's

LT Header's into dumps

What injectors will I need? Do you think 42's will do it or will I need something like a 60

& will a 255 pump keep up or should I do a 340/400?

Low 500 for a number. I would not even bother with the 317's. I ran stock comp when I had the p1 on he car and made mid 500's on 8lbs. Get the racetronix pump setup and 60lb injectors right away.

StangBanger317

So you think a Racetronix 255 will keep up?

Years ago i bought the racetronix in tank pump and hotwire kit and made 600rwhp on it as well on the stock line, rails, and 60lb injectors.

Awesome that is good to hear.

"Boost" is just the air piling up in front of the engine. The P1 on my 2004 GTO barely
gets 3 psi, so it's small for that setup. It runs great however and puts 500 to the wheels

Something doesn't sound right with that combination, or the boost gauge was wrong. Bob

I ran walbro 255 and hotwire 60lb injectors and ran out of fuel at 640 rwhp std so should be fine. Run meth!

your N/A setup is good for about 450 HP or so add 8psi boost on it then u get about 550 HP. A Racetronix 255 and 60lb injectors will keep up.

Sounds like a good setup, for sure get the 340 pump,question is not how much you will make but when you will build a forged block for boost lol

You should be around 520-550rwhp with that set-up.

Sounds like a 340 pump and 60's are in order. Looking to do a forged 408 bottom end over winter

I would definitely get a racetronix pump w/ hotwire and at LEAST 42 lb injectors to run 550 rwhp (should put them around 80-85% duty cycle under full boost)

But, im guessing 530 hp / 470-490 tq
