whats up guys, I'm just curios around what whp i should expect to run out of fuel? my setup is ID1300s. with walbro 450s in tank -10 feed and -8 return on E85. Any input would be great. I think base pressure is gonna be around 55-60psi. 2nd pump is on a hobbs switch.

i just closed the tab with fuel pump info on it...

but i do remember that walbro 450 is good for 550hp on E85. so like 1100. injectors should be good for 100-200 more than that.

Are you referring to whp or crank horse power

Those pumps don't like high pressure, keep the base at 3 bar. I was using 2 and made 1196 rwhp with- 10/-8 Teflon lines and e85. Just added a third

Was that through an auto car or stick car?

Since when are 130lb injectors good for 1200-1300hp on E85? Especially at a low base pressure so the pumps keep up? I'm curious as my 160lb injectors are 90-91% and I'm nowhere near those power levels. I run 3 Bar base pressure and keep my A/F conservative. I also log fuel pressure which remains steady so doesn't seem like the pump is dropping off.

Maybe he was referring to the ID1600 injectors OP has referenced in his sig and not the ID1300 he mentions in the post. Not sure which one he is actually going to be using

I do have ID1300, i thought it was going to be enough. I may just have to get tuned on these on low boost for now and swap later. Sucks.

I have been 165mph at nearly 3300lbs on id1300s at 50 base and less than. 80% idc. On e50

As you know E50 extends the capability of the injector a good bit compared to E85 so not an equal comparison. I so wish my turd could weigh 3300lbs, I started off about 1000lbs heavier!

Yes I realize this, part of the reason I run it

I could run that trap on e85 on the same base and the Injectors would cover it but the pump wouldn't. Injectors would be about done there on e85

What's your timing like on E50 vs E85?

iTrader: (5)

The same

Friend in here went 8.7/156 at 3800lbs+ on e85, 63base on 95lb Injectors maxed out

Good to know! Might give me a little head room. I just maxed out 160lb injectors on 3 BAR on e85 with some increased boost and timing.

What pump/pumps are you running

I'm running a 4303, it is done. It was not holding pressure on 50 at that level even
