what timing and split to aim for at around 30 psi
Alright guys, I was just wondering what timing and split I should aim for if i plan to run around 30 psi or higher on race fuel and my t78? Right now I am running around 25 psi and I am running 15 degrees with 12 degrees split. I was told by steve kan that this timing is good til around 25 psi. He tuned my car up to about 18 psi on the street and set me a starting map to tune on up. From about 18 psi, I have been turning the boost up a little at a time and tuning with my wideband for around 10.8-11.0 AFR.
Thanks for any and all imput!

the turbo is a pt 74 , dyno jet @ ptp motorsports (austin tx ) , and i run 4 1600cc
w/ the ptp dual pump setup. the s/5 stock ports netted @ 550 rwhp due to the small ports, but she flew down the track w/ the best of them. good luck w/ your setup!
