So what does it take to switch to E85? How much HP will I be making? Now I am making 420whp on 26Psi, with Tomei arms turbo, cams, valve springs and 750cc injectors.

 

larger injectors, a bigger fuel pump and a tune

 

That^^^. You'll probably be close to 500 whp after those things.

 

^ Definitely with the right tuner (TSComp )

FIC 1100's, fuel rail and one or two Walbro 255's and you're all set.

 

Another thing to consider is if you still want the option of running pump gas you might want to go with ECU based boost that way you can switch between normal gas and E85 if the need ever arises. If you're still on the stock DV you are probably going to have to either crush it or get something that can hold more boost since you'll be seeing 30+ psi no problem.

Getting an E85 tune was the most substantial mod I've done to my car. The torque is addicting. Makes me wish I had a built block and one of the larger stock frame setups for a nice 500/500-ish street car.

 

I'm going with the Grimspeed 3 port I know what you mean, my next steps are an MAP 2.3L/EF3 to go with my full bolt on setup. The torque is addictive for sure.

 

On a single 255, how much power can you make on e85 on E85

 

I'm on a single Walbro 255 and FIC 1250cc injectors and I hit 390/380 on E70 with just cams and bolt ons. Those numbers are on a mustang dyno I'm sure if I had it on a dynojet I'd be deep into the 400s.

 

Apparently catch cans are nice to have. Not needed though

 

I'm on one pump and 1600cc injectors with stock 05 evo 8 turbo and i hit 405whp/394 tq.
E85 is a blast it just hits so much harder then normal fuel it is deff addicting.

 

im on a single 255 and 1000cc injectors making 450whp on e85, 28psi. if i could do it again id go all out and get a double pumper and 2000cc injectors for future purposes

 

and tephra mode.you never know if your car starts easily when temperature is lower then 40 F.i have that problem so using tephra i switch between fuels when needed.and be ready for 200-220 miles from full tank of e85

 

If your car struggles to start when its cold on e85 then you need to look for someone else to tune the car who knows what they are doing.

 

maybe you right.but i know that i am not only one who struggles with cold start.some are lucky some are not.

 

mine struggles some on colder start days (minnesota) but e85 is well worth the money. if you have a daily driver its a must and if you dont just get dual maps and you can run 91/93 octane in colder weather.
