Hey guys I had my latest combo dynoed last night with the following combo:

ATI P1SC Procharger
SDCE 8 RIB set to 14 psi @6600 RPMs
Front mount OBX intercooler
Stock LS1 block bored to 3.905
New LS1 stock crank
Lunati LAE1 rods
ARP main studs
ARP head bolts
Diamond forged dished pistons
02 LS6 cam and springs
hardened pushrods
Stock heads w/GM head gaskets
LS6 intake
Ported throttle body
F.A.S.T. fuel rails
SVO 42 pound injectors
255lph in tank fuel pump
Hooker Long tube 1-3/4” headers with off road Y-pipe
Hooker 3”catback
NGK TR6 sparkplugs
MSD 8.8 wires


I made 606 rwhp and 524rwtq through a Moser 12 bolt with 3:73s
does this sound about right?

Nice numbers...

Man... I only got 533 out of my 42# injectors and I was at 109% Duty Cycle, swapped to 60lbers while still on the dyno and went back to tuning.

Be careful with the 42s!

P1SC? I thought they only went to 7lbs?

What could I pull with decent 1.6 60ft? on ET streets? anyone's guess?

Blackbird

change those injectors right away!

or what your going to do is pop that nice new motor on your ET streets.

i thought the P1SC maxed out at like 11 psi

Centrifical superchargers put out X amount of airflow. A 346 ci engine isn't going to require as much airflow as a 382 ci to make boost. Othyer variables would be better flowing heads, cams, etc. The use of a stock crank keeping the 346 ci, plus the use of a LS6 cam, and stock heads, would attibute to this P-1SC putting out good boost. I am surprised that it made 14 psi, the SDCE assembly is more than likely responsible for it.
As everyone has mentioned, please jump up to 60lb injectors before something bad happens to your engine. Your 42lb'ers have to be seriously maxxed out. Bob

Nice #'s.

He's probly getting 14lbs because he is ussing stock heads. Boost is measured by backpressure.Throw on some ET or AFR heads and pressure will drop,but hp will probly go up.

I'd say high 10's as a guess. Bob

I was real impressed with the power the car made Saturday! That was the most power I had ever seen out of 42's or a P1SC. The A/F was rock solid in the 11.8 area and crept up to about 12.5:1 there at the very end of the pulls. Some 60's would be a good bit safer.

How much work would the tune be from 42 to 60s?

Not a big deal at all, change the IFR table and dial the PE table in again. Let me know when you are ready to do it.

12.5:1 on the dyno will easily lean out to 13:1 or leaner on the street.

car probably runs good though right? a4 or m6?

impressive numbers, my goal is to over 600 to the tire too. Need mo booooooooost!

I guess some 60s are in my future!

Nice build. Tell us what you think those 3.73s are like on the street.
