I am trying to calculate the max power I can get out of this setup:
- Single Walbro 255 HP in tank (w/rewire)
- ID 1000 Injectors
- 6AN feed
- Stock feed line (5AN) as a return
- Stock fuel rail (regulated 1:1 before the rail).
On pump 93 I am confident I can get 450whp no problem. What is the max for this setup running E-85?
I know everyone running E-85 is switching to the Bosch 044 in tank pump, but that requires cutting up the stock surge tank. I don't want to do that.
Can I get away with the above setup for 400-425whp on E-85?
This one is a trick. And it's related to fuel pressure. The 255 could push enough fuel for your 450 number on E85 - if it didnt shit after 70psi.
your in the 380-400 range on E85.
Those ID 1000's need pressure (040 or 044) for E85, they just need a 255 for Gas.
I think you may like the bosch 040 it is small enough to fit in our cannisters for sure. Lil bigger then a 255, but TONS more flow. 289LPH to the 044's 300LPH. it's also good to 100psi.
This would allow you to get to that magical 1525CC number with your ID 1000's - otherwise you have to commit to E85 and go with the ID2200's They idle fine on E85, not so fine on Gas.
the 22's with a 255 would make your number at the lower pressures.
This in terms of base fuel pressure. For 500ish on E85 you need a base of 70psi, with your Vac you pull about 10psi out at idle so 60psi idle pressure, then I used 30 psi of boost, so at 30 psi of boost, I was seeing 101psi of fuel pressure, and my 1000's were flowing 1525 and only working to 80% duty cycle.
I hope thats clear.
