Damn! Really nice numbers Joe!
Yeah i didnt think id actually have to limit it to number lol. i just honestly think its at the end of the rope of pump gas, so why pushit? The 80# injectors (technically 101# @ 58 +psi) are at 83% DC and i dont like to use the meth as a crutch. Honestly, with going for it with the meth and 20+ degrees of timing, it would be damn near 900. It was just touching 17 psi (221kpa) by 6300 RPM. Right off the street tune it made 768 with 14 degrees timing and 10.8 afr. Leaned to 11.1 and moved to 15 degrees it gained about 30 hp, then the meth added about another 15. best part is, it drove home under its own power afterward!

Tooner fight! bahahahah
It has a rising rate FPR 1:1 58 PSI base. Its just the math in the PCM makes that injector out to be a 101# @ 58PSI above 80 KPA. With the 17 PSI rise in pressure of fuel psi to combat the 17 psi manifold pressure, in my head anyway all comes back to what things are like around that 58 psi mark again. I could be all wrong too.

Awesome numbers Joe, Once I get my diff back together ill have to run it on the dyno again!!
Congrats, I'm sure its great to be driving the car again

Mah bad... I thought the 58psi was not base pressure, but after the rising rate. Sounds like he is running 58psi base + the rising rate (which BTW is pretty high fuel pressure!)
Basic premise is that the injector size depends on the value you use for the base pressure. However 101# is still not the right number... not sure where that is coming from?! Injectors are rated at 43.5psi (3bar). So if they are rated as 80# injectors @ 43.5 base pressure, then they would be rated at roughly 92# injectors at 58psi base.
Congrats Joe.....Nice Job Tom and West Bend Dyno!
So what were the gains compared to the old blower?
beasty figures man.
