Alright so i just had a few questions about a set-up i am working on and looking for some information and input.

Set-up

00 jdm itr
vortech high output kit "10psi pulley configuration"
large water cell
large heat exchanger and power cooler
aem meth injection "going to run 50/50 meth/water or what-ever my tuner decides"
id1000 cc injectors
walbro 255 fuel pump "will this be enough?"

Now what im wondering if if it would be worth it to run E85? I hardly drive the car so im not really worried about always having a close local gas station and they do sell e85 at a station only about 15 minutes away. I have a reliable dd so im mostly looking to just enjoy it on the weekends and have some fun. Im only going to be running the 10psi set-up because its stock internals but it has quite a few supporting mod's including a ported intake manifold, larger throttle body, 3" coverted header to a 3" exhaust with e-cut out etc etc. Made a solid 200whp/134tq as it sit right now all motor. So i know it will make decent power with the vortech kit and larger supporting mod's.

Just curious what kind of gains are achieved by running e85 and is it safer to tune on? Only thing that makes me nervous is boosting a jdm R motor with 11:1 comp but im going to run meth/water to help with this and am considering going to e85.

Fuel setup:
aem fuel rail
aem fpr
id 1000's
walbro 255 "what kind of whp would a walbro pushing e85 support?" I am hoping to make less than 350whp on this set-up at that boost level to keep it reliable
inline i believe "aeromotive" fuel filter cant remember off hand

As far as i know thats all i would need besides the e85 itself. Just looking for opinions or information on the matter. Thanks Guys!

 

no, if your running methanol injection, depending on your base fuel your getting anywhere from 98 to 101 octane, walbro 255hp pumps are usually good for insane amounts of fuel and i wouldnt worry about e85 with the methanol injection, especially at a target of 350hp which it will be more then capable of with the centrifugal supercharger

 

I would honestly ditch the meth and go all E85...

 

lol not everyone has e85 availability like others, i know if i wanted to run e85 in my car id have to drive 35 miles every time to fill up

 

like gringotegra said I would ditch the meth kit and just go all E85. I'm running 11.1+ CR on my b16 on top of boost and my motor hasn't had one hiccup! E85 loves compression!

 

I have been running E85 for over a year on a boosted b18c. It's a DD and I am looking really hard at methanol injection. it's a pain trying to find E85 if you go on trips. Every winter it reduces to E70. Dont get me wrong E85 is a great safety feature on high compression engines, i just think the meth injection would work as good as long as it was a regulated by boost system.

 

E85 > Than meth injection..

WAAAAAYY >>>>>

 

If you run e85 the water/meth injection is pointless. I made 522whp on e85 and I plan on making 800+ e85 only. Td Autowerkes civic ek made 1100whp e85 only. But on another note For 350whp just run pump gas. I made 425whp easily on 93 pump gas.

 

i know i could just run pump gas and make decent power at 10psi but just looking to make the most out of my set-up for the time being, just was debating between meth injection or e85, not a whole lot of e85 around here but i dont drive the car much and i know theres one pump about 15 minutes away that has it, the power cooler is already tapped for meth injection but could be plugged

is it necessary to run either 1? probably not but then again i dont usually like doing things the easy way

 

For the power you want pump gas is more then enough. Having meth injection is just another head ache. There's a saying that works most of the time k.I.s.s "keep it simple stupid"

 

X2!!!

I really don't like meth injection, especially not when compared to E85.

 

There is about 4 different people saying to stay away from the meth injection and use only E85 have you all started on meth injection and ditched it for reasons. Honestly I cant see where their would be a difference. What are the reasons for not using the injection as long as it was proportional to the amount of boost. Not tryin to discredit all you just want to make sure you have tryed it first and then ditched it.

 

I have never personally ran meth injection, but I have seen other peoples setups with a meth kit, never ran bad. IMO I just think E85 will be dispersed better and every cylinder will get the even amount of fuel. with meth if you have the traditional nozzle by the throttle plate, i've always thought the cylinder farthermost away wouldn't get as much meth as the rest. Plus a meth kit has more parts to it which means you have a greater chance at something failing. If your running E85 I know a injector can fail but the chances of that are alot less than a wire coming loose or pump failing on a meth kit. Plus E85 cooling properties are damn near unbeatable even compared to race gas. I dunno how the IAT's are compared in E85 vs Meth but I know my car has a very aggressive tune, buttloads of timing and 17.0 AFR's in closed loop for gas mileage and my car hasn't seen a bit of knock or detonation. my motors CR is 11-1+ mind you.

 

Put it this way, if your Meth fails... kiss your motor goodbye... You can put fail safe switches on it and what not but **** can and still go wrong...Ive seen alot of motors go boom from meth kits failing...

the walbro and the id1000's will get you to 480-500whp on E85 so you are good with them...
