E85 Fuel Injector Sizing
I'm planning to run a EFR 8374 at 20-25psi boost on a street ported 13b-rew motor, planning to make 500-550whp on E85 gas.
43.5 base fuel pressure
85% duty cycle
Would 6 x ID1300X injector (total 8040cc flow rate) be sufficient for my needs?

Is this a flex fuel vehicle or purely e85? How did you plan on controlling the injectors?

purely E85, Haltech Elite 1500
planning to use a flexfuel sensor just incase the e85 % lower in a batch of fuel
Hoping someone can check my calculation to make sure these are correct, injectors are expensive lol

I was under the impression that the only 'true' E85 ID injectors at this point were the 1050x and 1750x.
I have built around the basic rule of thumb that e85 carries 2/3 the BTUs of gasoline, so at minimum increase by at least 1/3. This doesn't factor in the timing you're able to throw at your engine when you convert to e85 so again, rule of thumb.
Either way I think you'd need ~8400CC at around 80% duty cycle so you're very close, just make sure that those 1300s are e85 capable.

The ID725/1000/2000 have all been successfully used with E85 time and time again. Hell I used my ID2000's for 2 years and during which they saw about every type of fuel you can imagine, including ALOT of E85, when I sent them back in for servicing/inspection they passed with flying colors.
You won't have any issues running E85 on ANY of the ID injectors.
