E85 and 800cc injectors and 19 psi = .........
 

Well I found out how much 800cc injectors and E85 makes….

Not much.

The motor made a max of 288 whp/330ish torque @ 21 psi and ran out of injector @ 6000 rpm.

Turning the boost down to 19 psi was 265 whp with a moderately safe tune. But the MAF was hitting 5 volts with the piggyback adding in voltage up top….

This was done @ PRE in Gresham Oregon on a DynoDynamics dyno. Sorry, neglected to get a dyno sheet. The torqe and power curves were good up until 5000-5500 rpm when I would start to degrade a bit. I was having some missing issues (we were pretty sure it wasnt det), and this could have been old sparkplugs. The AFR line was pretty damn ugly. "Safe" but ugly. The Walbro 255 just wasnt able to pump enough down low 4000-5000 rpm, then the fuel pressure would ramp up some due to the boost level, then the MAF would run out.

Since it may be awhile before I find (if ever) 1200cc sidefeeds, I am switching back to gas, as I have made 100+ more hp with the same setup.

Ah well, I just wanted to see what the injectors and E85 was good for, and now I know.

quite interesting

good luck with your build. might talk to the injector rehab guy and see about a possible hook up

Dont blow here up again :6

is this the turbo and supercharged suby? thats kinda weird that you didnt have luck with it.. whats the reason you think?

Re: E85 and 800cc injectors and 19 psi = .........
 

No, I have great success with it. But need to run gas versus E85 with the injector size I have right now.

the lower energy content/gal of E85 compared to gas

Re: E85 and 800cc injectors and 19 psi = .........
 

E85 makes more power than gasoline at the same pressure, you just have to inject more of it to get the same amount of BTUs. It likes to be run a little leaner, tho.

i made a lot of power with it.. but oh well

Re: E85 and 800cc injectors and 19 psi = .........
 

my buddy keeps his AFRs right around 12:1-13:1, and when he had 1000ccs and a 255 he put down over 500 on 14psi. now he has 1600ccs and an a1000, and puts down 532 on 15psi.

i would think you should be able to get more power out of your set up, but who knows. also, i was told they tuned his on lambda. dont know if that changes anything for you.
