I want to know what i need to do to convert to E85, fuel system wise. Im runnin a built boosted K series in an EG hatch and i dont like having to run race gas to go over 400hp. Id like to be able to run any of my maps at any given time without having to worry about changing fuels. A little backround: Car on high boost makes 600+ whp. I have precision 1000cc injectors, earls racings in line fuel filter, 255 pump, and stock fuel lines from the firewall back to the tank. Ive heard the lines have to be bigger and i might have to run bigger injectors and a bigger pump. My question is, being E85 is so cheap and can be used on my higher boost level, is it worth while to convert it to run E85? Mind you, this is mainly used as a street car. Typically in the summer time ill drive between 100 and 250 miles a week. And i track it maybe 2-5 times a season, if that. Also, i am running Kpro.

Any help would be great!!

all u need is a bigger fuel pump and injector which u all ready have but now converting u will need to retune the car my tuner told me u won't see much of a diff between e85 and race gas btw im using stock fuel line and they have not gave me a problem

Im not looking for a difference in Hp, i just want to be able to run my high boost tune without having to run race gas.

plus E85 in my area is only $2.70 a gallon, which is way better than race gas being $20-$25 a gallon...

You would most likely need like 1600cc injectors to get back to 600+whp. And a new tune. I run it in my gsr and I'm on 1000cc injectors now. It works great cold starts are a lot better too. For bigger lines I'm not sure I'm at 360 with everything stock. For ur goal you might need bigger lines cause I know e85 uses a lot more gas to make the power of regular unleaded.

you dont need 1600cc to make 600+ man im doing it on rc1000's at 23psi.
a new tune is needed for sure though
im on -10 lines though, and a a1000 pump with base set at 60psi

I've seen a 380whp civic max out the duty cycle on RC1000 on E85. Just remember it takes twice as much e85 to match the power output of gasoline. I guess it will depend on the tuner.

Sanman what duty cycle were you running your injectors at?

2.70 a gal?! its 1.99 where i am.

Im making 505whp on E85. I upgraded the entire fuel system but you'll be fine with stock lines/rail/filter - just need alot of pump & injector.

sanman000719

my duty is 98% on kill

but remember the base is 60psi not 40psi and that means im near 1200cc from the injectors not 1000cc

I pay less than $2.00/gal most fills for E85 and get comparable gas mileage (24-26 city / 25-28 hwy). The only switch i made was to a larger set of injectors (PTE 1000s) and i've had no issues. With your goal of 600+, you're going to need a large set of injectors, but nothing that can't be done. You will need to look into either a dual-Walbro or an A1000 pump to sustain that kind of flow. As for injectors, a set of 1200cc should do it, but i would go larger to be safe. Also, you could look into Injector Dynamics since they seem to outflow their claimed rate...their 1000s seem to be more like 12-1300ccs which is never a bad thing

sanman000719

yes 30% is the orrect answer lol

ReDemoN

Where are you buying race gas for 25 a gallon???

I'd rather not have my injectors at 98% duty cycle and get the 1600cc. Why blow ur motor for a couple hundred bucks

sanman000719

well not that i dont agree with you, but this has been my setup for 2 years now with no issues at all in that area. now rod bolts are what usually gets me.

i wouldnt even run 1600 ide just go id2200's and be really nice

sanman000719

my point was you can obtain the h.p. goal with 1000's

I would like a pump i can retain in the stock tank. Which one would be the best for that, if possible...

Im not sure what my injectors are running at on high boost. Im not planning on running my high boost level which is 30psi. I wanna keep the motor somewhat safe and try to keep it at 25 or less. So i suppose whether or not ill for sure need bigger injectors is a question my tuner can answer for me. Im thinkin if i keep it at 25 or below, i an get by with the injectors i have and maybe the fuel pump, but if i wanna go higher in boost, then i can always upgrade down the road. Mainly this car will run between 13-16psi on the street cause from what ive experienced in the car, 400-450whp is more than enough to keep me entertained.

Maybe i was mistaken on the price of E85, might be around $2.17 near here. Im in the chicagoland area and we are known for having the highest gas prices in the country so who knows. ill have to look into it.

sanman000719

you can run dual walboroughs in the tank man they make a sweet hanger for duals

Psychoteen101

Could you post of link where i can find that??
