Easy rule of thumb that seems to work is CC=RWHP for e85. 850cc will make 850rwhp. 1000cc=1000rwhp. etc.
Assuming you have enough pump. I think that is a lot of peoples problems. If fuel pressure drops off, then all bets are off. If you can hold 60-80psi, then no problems. A lot of people 1/2 *** a fuel system, so they make up for in oversized injectors and ramp them up to make up for dropping fuel pressure.

You're probably right.. that's a lot of fuel to move at 60-80psi
Crazy. Speaking of which.. I wonder when ID is going to release their brushless fuel pump. I saw something on facebook about it a few weeks ago

Gotcha. For some reason I was thinking 1rwhp per cc on gasoline, so would need about 30% more on E85 obviously. I'm even more overkill on injectors than I thought then.

I saw where ID1000's are good to over 100psi of fuel pressure Crazy.

Yeah, I'm sure it won't be cheap, probably comes with a controller. Seems like I saw some flow #'s somewhere and they were pretty ridiculous
There's no telling.. seems like Paul Yaw is always posting about something new. Suspension parts, fuel pumps, bosch ECU, spark plug w/cylinder pressure sensor, etc. but so far no new products that I know of.

Figure it this way, 43psi to 60psi is almost a 30% increase, so just setting the base FP up would make the difference between gas and e85.

My bad. Either way you can get a lot of extra flow with pressure.

Where's a good place to pickup the ID 1300 injectors? Also wondering how I can tell if both my existing fuel pumps will handle e85? Guess I also need to know if the fuel lines can run it? Thanks.

Was reading somewhere that 1300's are back ordered forever. I guess someone must have some in stock.
Oh. And ID has a flow calculator on the site that has been dead on every setup I tested it with.

@schpenxel I can't find you message but you were saying they had some problems causing them to go on back order, it was actually the 1700s https://m.facebook.com/notes/paul-ya...6328148185338/
