How much RWHP have you managed to squeeze out of your P1SC-1 on your LS1?

Last time the car was on the dynojet it was at 500 RWHP, and I'm wondering how much more hp can be gotten out of my P1SC-1.

Thanks, Matt.

 

I have 550 rwhp but on a 408cu motor. Im trying to figure out how much more also.

 

I'm making 550 with stock cubes and with a aftermarket cam.

 

highest I have seen reported was 630rwhp

 

I've hit 580rwhp with my P1,headers,stock motor.I just detune it to around 500hp for longivity.

 

Yes, Cartek has a silver vette out there making 630 rwhp.

 

off topic but Big Mike how did you reverse the "R" for redrum??? i love it

I made 547.9 about 2 months ago... just waiting on a new pulley and i should be around 6-something....

 

My numbers are low because my compression ratio is 8.5:1 and I have a relatively small cam for my motor

 

To get the most RWHP out of the p1sc-1, what is the ideal compression ratio should I be looking at? Also with (hopefully) around 600 RWHP will it be ok to use the stock crank?

 

Around 9:1 should be the best for maxing out the P1. On a typical build you shouldn't be able to get more than 11-13 psi, which is okay for 9:1.

The stock crank is fine.

 

If you want to donate your dyno and time I wouldn't mind trying for 650+ on my P1SC. I'm likely going to be switching to a D1SC in the near futrure and I'd love to see what the P1SC will do vs. the D1SC.

We should talk, I was going to contact you soon about a tune and maybe an quick install.

Don (Slowhawk) is the man. He has done quite a few procharged cars.

 

546 hp and 518 tq with 8 psi...

 

See sig

 

I've done 650rwhp on a mild H/C /forged 346 with a P1. A D1 can push it well over 700rwhp We are currently putting together a mild forged 346 with an F1,looking for 850hp or so

 

Hotcam, Stage 1 Heads, Stock Cubes, Stock Crank, forged internals, 9.2 to 1 compression, 12 Bolt w/3.73's P-1SC Blower with COG setup spinning the blower to 64,000 impeller RPMS at 6500 engine rpms.. 11 psi of boost. Dynoed 621RWHP... Gone to different setup now after blowing the P1 up... Over 700 RWHP now, no dyno to prove it yet..

I made 569.7 and 477 RWHP with my P-1SC-1, stock compression at 10# boost and the Speed Inc. SC1 cam through an A4 with SSF 3500 stall.

 

I am curious what pulleys you are using to achive the power.

 

587 RWHP sae corrected. 2002 ZO6 vette stock heads,cam with LG headers and X pipe not cats. Tuned by me and my buddie. Andys A&A kit makes some badass power with no belt slip. But its a ************ to get that belt on LOL.
