can i run e85 on it and how much boost can it handle on gt35r on a k20a2

 

yeah it can handle e85 just fine. mine does.
but a gt35r and a bigger motor?...try it.
depends how much power you plan on making. over 500hp. i would be safe to get another pump(xtra pump) inline pump
sumwhere on H-T there is a "fuel setup thread"

 

ive seen a walbro 255 used up to 650whp

 

thats good to know. how long did that last though? for real just asking, cuz i dont want to mess with fuel and add pumps and lines. ill mess it up if i do that.
not to thread jack. but i think the answer will help OP as well

 

Boost is irrelevant, if your running a return to tank style fuel system and 1000cc Injectors you should be about out of fuel round 500whp +/- 25whp with a single 255hp EDIT: with E85.

congrads, bet it didnt make that 650 on E85.

 

oh...dang

 

so what if he is using like 93octane?
he could make 650 on pump but not e85?
(how fuel workx is over my head)

 

^^^^ Each Walbro 255 is a little different, some go way over what they should make and some are slackers. E85 requires roughly 30% (again +/-) more fuel to make the same power as gas.

 

...so. i should drain my tank and use pump gas?
im thinkn about it cuz theres only 1 place here that sells it

 

What are you talking about, how should I know if you should use pump over E85? I know nothing about your setup, goals anything.......

 

well if e85 is pointless and uses more gas to make the same power. why should we use it?

 

Dude your an odd one, who said anything about pointless? So by one of your previous comments your using E85 currently? But you dont know about any of its advantages?

 

the guy that tuned my car told me to fill up on it, he said "its cheaper and higher octane"
so i was like whatever and filled it up.
i dont see a dif besides the awesome rotten corn smell

 

How can a fuel that is cheaper and higher octane be pointless? Your tuner already answered your question. With the fuel change you picked up 10-15hp alone, and since its higher octane you could run more boost/timing if you choose over pump gas, thats why people run race gas.......

 

never mind

 

thanx for the info i got rc 1000cc injectors and welbro 255 i want to make like 475 to 500hp with gt35r on k20a2 only reason i want to tune on e85 is because it cools the engine down.

 

what are the hp "limits" on e85? any info on 100 octain as far as hp "limits"? sorry for the thread jack.

 

Not really, your coolant temps and iat's will still be the same......

1000+hp, E85 is 105 octane
