e85 > 725cc inj

[ST3PH3N'S SRT-4]

Well today was my first day with straight e85.........

setup:
60 trim
Perrin Fuel Rail
RealTune 725cc injectors
Fuel Return (steel braided line)
Fuel pressure regulator @ 60psi
Walbro 255 lph fuel pump

started off @ 20 lbs off boost 13.0 to redline
then 18 lbs, 12.8 to redline
16 lbs, 12.6 to redline
14 lbs 12.5 to redline
10 lbs 13.0 lol wg didnt even open

was trying to think of new fuel setup to fit my needs of 550-600whp range, any advise?
was thinking about going with a bigger inline external pump fed by walbro 255 but not sure. Maybe even just a Aeromotive A1000 Fuel Pumps and thats it...And inj size, no clue.

thanks
stephen

im closer to the 1000 range at the FP im at then the 900's range.
bottle neck fix?
i have -6 to the rail, and a inline booster pump to keep volume above 300lph till after 65 PSI

a normal walbro 255 is only flowing ~200 - 225 lph @ 60psi, then if its 1:1, at 75 psi its only flowing 180-200LPH (depends on voltage, and room for error)

if i was to do it again, i would do 2 intank pumps, the inline pump has caused a few problems, its a inline walbro 255

today at the dyno, at ~50psi fuel pressure, 25 PSI, it was ~12.5 at redline

[19 psi]

today huh....so uhhh what numbers did you get...lol

also... do you notice with those 900's is it rich at first at all and then get to 12.5, or is it pretty much lean the whole time?

[amdguy]

still working on the tune, its to the same point i was last year with 110 in it, with 1 PSI less.

it was pig rich in the mid range (3k till 4.5k), so my spool was killed. i ended up with 417whp

this is a car with a stock head, stock Thorttle body, and very little timing. advanced the timing a bit, and leaned her out in the middle and she felt ALOT stronger
