E85 conversion serious question and don't want bogus answers!!!
Ok well I am currently running a 02 mustang with a 5 speed. I have a comp cam, ported lower, windstar upper, lts, and full bolt ons. I am going to be getting another vehicle for my DD here in about a half a year. I am wanting to build up my stang with a better motor. I already have heads I am in the process of porting. Here is what I am thinking.
Ok I want to run right around 13:1 compression ratio. I am not sure if I want to run a 4.2 or a 3.8 bored both with forged internals. I don't know if a 4.2 crank would handle 13:1 compression ratio or not?
Next I would like to upgrade the cam to a bigger cam.
I know I would have to upgrade the fuel pump and injectors since the e85 needs 20-30% more fuel. I am actually thinking with the increase in CR that I will not loose too much fuel mileage roughly 10%. I am not too concerned though.
Basically besides the fuel pump and injectors do I have to change any lines or anything to make the switch to E85? Also would I be able to tune the car to run on 91 octane with tons of timing pulled for an extreme case where I cant get E85 this tune could be capped at like 3k RPMS. Not sure would have to discuss with the tuner for this.
I am wondering what kind of power potential there would be for this motor? I am thinking this could be the highest NA HP 3.8 mustang motor. E85 has a lot of potential due to lower combustion temps, cleaner burning, plus 100 plus octane and it is cheap.
In summary do you think that I would need a super coupe crank for 13:1 CR or could I use a 4.2. Would I gain anything from the longer stroke? I am hoping to make the most extreme v6 yet.
