80lb injectors for 6-700whp(e85?)
i didn't ask about the timing- he did comment it was safe.
but adding more timing may have yielded more HP but more HP requires more fuel right -and if im already at 90% DC
the car did spin on the dyno so not sure if that cost much HP.
Jacking the fuel pressure up to 60 will affect the tune and require a retune.
ive followed your builds and like them a lot- I regret going with HP tuners and wish i would have gone MS now but I already bought the harness, pcm etc for my swap.
What pumps and fuel pressure did you make the 697 at ?
im *** deep into HP credits and dyno time but may make the switch to the the MS3 later.
I saw you post that they were working on a direct fit lsx application.

From what I’ve read you need 35psi minimum to get a decent spray pattern on the injectors. The more pressure the better the pattern/atomization of the fuel.
Honestly with the new badass 450lph e85 walbros I don’t see why people are still using the 255lph pumps.
Going by my experience with 120lbers I don't think 160's would idle well, even with E85. My idle is bearable, but I can’t get the pulse width high enough to get a great idle. Going by my DC numbers 120’s should support 1000+ on E85 at reasonable pressures.
I run:
40psi base pressure. (20lbs of boost)
magnafuel 750protuner pump (loud bastard!)
1/2 feed lines and OEM fuel rail
120lb injectors (low-z with AEM driver box)
E85
Logs showing 55% DC at right around 700whp (going by weight/trap speed)

What will the stock lines and rails support on e85? Thinking of going 80 # Deka injectors dual Walbro 255's stock feed line 1/1 fuel pressure regulator and use the evap line for the return line. Think that will support 800 rwhp?
Made over 700hp with my old 4.8 on 20psi... Dual walbro 255s, SD60s (73lb/hr at 58psi) and 50% e85. Top of the gear around 6400rpm was 90% IDC. 700hp on 100% e85 with 80s will be no issue...
