Our 3rd Gen club had a dyno day today with a little tuning aloud. My previous best was 304RWHP and 334RWTQ. With the addition of the Meziere electric water pump and the Mufflex 3.5" catback with Magnaflow muffler my new numbers are 322RWHP and 351RWTQ.

Numbers would have been better but we could not get the tune right in the limited time available. I'm now running at a 12.2 AFR. Reason was I cranked up the fuel pressure to 50PSI as I was running out of injector size. Duty cycle was going well past 80% with the fuel set at 46psi.

Figuring a 20% drive train loss that would put me at 402HP and 439TQ at the motor. So I believe I have achieved over 400 HP with TPI and a 350 motor. With my next 5 mods I hope to be well past the 400HP mark. By the way there were some very good numbers put down today and I will let them post their own results.

Some are already posted in the Southern California section.

 

good numbers,i personally feel you will gain a few more ponies with the speed density conversion and a custom chip.good job though
