ok i'm finally ready to run it for timeslips.
first few runs will be 4 psi. a little tuning then 6psi. gotta get an idea where i'm going from there.
with 2.73's and street tires i still expect decent times. just cant power brake it off the line.
i expect 2.1 60' times. the fact is this motor runs like any other b head motor. very little low end then it never stops building power.
i have it programmed to shift at 6200. i'll up it to 6500 after a few runs. the boost is at full by 2500. but b heads still dont do well. the few street 'things' ive done put it about even with a late model GT until i get to 5000. then things pick up a bit.
ill tune it as i go. i have it tuned VERY rich right now, right on th verge of missing rich. im going to pull fuel in .5 a/f per run. get it close to max hp and add a little.
then add a couple of degrees timing mid and up top.
4 psi should be 400hp based on VE and compressor map caculations.
6 psi should be 440ish hp
my turbo inlet is needing to be changed to the 4" stuff i have but im waiting.
it will cost me a little power.
at 6psi:
60 Foot 1.63 ...................:2.13
330 Foot 4.70..................:5.20
660 Foot 7.39..................:7.89
660 MPH 92.....................:the same
1000 Foot 9.72
1/4 Mile ET 11.71
1/4 Mile MPH 113.16
those are ideal. but with 2.73 take maybe . 5 out of it.
im changing gears after i figure gas milage. i used 5.35 gallons to travel 160miles.
i need to keep as much of that as possible. we'll see how close i get to the 'ideal' numbers. honestly 8.2 with 2.73's would satisfy me at 6 psi.
