So barbs on each end can be used to add the bosch 044 inline and then with the fuel pressure increased via a fpr, can be sufficient enough with id1000s to support 600hp on e85?

 

Bump.

Interested in opinions on if I could run E85 flex fuel setup, Walbro 416 in-tank pump, ID1000's, and not run out of fuel to support 16-18 PSI supercharger setup. Currently at 390 WHP on 93 octane, looking for 450 WHP on straight E85. Possible? I have an AEM FPR and would feel OK raising base pressure to 50-55ish, but don't want to go too high because I'm afraid it might not run right when on straight 93 octane.

 

I think youll be fine. I was talking to my tuner he said for my boost level i should be fine. I was already willing to drop money on a new pump and injectors.

my set-up

aem 320lph
id1000
aem rail
stock fpr

Since our setup is so similar ill let you know what happens after the dyno.

 

Thanks for the reply, my not-so-evil twin.

I also currently have the (Aeromotive) 340 pump, ID1000's, stock rail, but AEM FPR. I was under the impression that the 340 pump wouldn't be enough to feed the ID1000's which is why I was looking into the Walbro 416. I have my pump hardwired (as do you, I believe) so it should be outputting the max of what it is capable of. Very interested in your results.

 

Have a friend with ID1000 and one 340 fuel pump running E85. He made 576whp on a dyno dynamic.

I'll be going to the same tunner to tune my car.

 

Well hot damn, Flex Fuel here I come!

 

So when you guys got tuned for flex fuel, did you just do a regular tune on 93 octane and then another tune on E85 to determine your timing/fueling adjustment percentages? Or did you also do a third tune (or more) at a lower ethanol mix to get another reference point in there?

Basically what I'm asking is does your flex fuel tuning just linearly interpolate between two points, one being a 93 octane tune and one being a E85 tune? Is it assumed to be a linear curve between the two points for the timing and fueling adjustments?

 

E85 allows for a higher margin of error in tuning before detonation and so you can assume a linear relationship.

I tune two points, 91 and then E85. Then run mixed of 91/E85 close to 50/50 to verify O2 and timing. The A/F ratio is usually spot on linearly with O2 feed back. For timing, I run a slightly less timing up to E50, and then extrapolate to the E85 timing. I don't think it is worth my time to try to optimize the timing in between. What I am looking for is to make sure there are no knock voltage spikes between those two points.

Most of the time I would be running E85, and if I would have to pump 91, I wouldn't drive as aggressively until I'M back to E70 or above.

 

Thank you for the excellent response.
