Planning on running e85 my goals are 330-350whp question is how much more bost can I safely run on e85 vs pump on stock block. Also how much boost will I need to get there

this should be a question for your tuner!

Why does it seem that everybody thinks E85 is magic of some sort? And I don't think you're getting 350whp on a stock block no matter what fuel you're running.

the red eg

Ok well I'm sure I would be happy with 300 whp. Was just wondering about the e85 new to it.

as far as a wide band will I have to get 1 specific for e85 cause I have seen that aem makes specifically for e85. Or will regular wideband work

Stick with pump for your power goals.

E85 is nice because it burns cooler and you can run less boost but for 300-350WHP you won't need much boost anyway.

The goal is to keep it simple.

You can also ditch the rail and regulator to save some money; they are not needed for your goals.

doesnt E85 have alcohol in it?

mechanix619

Ethanol alcohol

Hey dude just look into it more and research E85 availability in your area. E85's "cooling effect," which is a product of its higher heat of vaporization, allowing it to absorb more heat in the intake tract than gasoline, is great, allowing a cooler, denser incoming charge.

Also, its higher octane compared to standard pump fuel makes it attractive, but keep in mind that octanes are not always as high as advertised, i.e. use AKI or anti knock index, which is the RON and MON octane values averaged (R+M/2) for a more accurate octane value. There is currently no federal law requiring stations to advertise the octane of E85 fuels at the pump. The E85 you're putting in your tank could possibly be E80 (80% ethanol/20% gasoline/additives), or E75, etc...For consistent performance and filling, buy E85 by the 55gal drum from reputable companies such as Rockett Brand, who openly advertise chemical blending information of their product.

Which brings us to trade offs. E85 availability and quality in your area, how is it, wheres the nearest station to get it, what if you run out of E85 when you're out in B.F.E....these are just questions you want to ask yourself, they might apply, they might not. Another aspect of this to consider is that E85 has less potential energy per unit if you will, so it takes about 35-40% more volume to make similar power, therefore you'll need to make sure your fuel pump, outgoing lines, and return from the regulator are all of adequate size and capability. Your tune will be different as well.

It is very cool stuff for sure, just not right for everyone's application. As a daily street car with moderate power levels I don't know if it would be worth it, but maybe for you. Ask people who run it.

the red eg

Already have the rail and pressure regulator.

Smooth thanks for that info. I have to looked around for availability there are a number of stations near me. My tuner uses e85 in his cars.

I figured I could make that power on pump but thought that e85 would be a little safer since its cooler.

CrisFerio

It runs dry...

E85 is magic when it comes to the price per gallon. Yeah the mixture of E can vary but all you do is tune it on the safe side or get a meter to ready eth content. Ethanol runs cooler than most other fuels which is a big plus and it's better for the environment.

350whp on a stock block with a decent tune is cake walk, I did 400whp on stock c1 with 11:1 c/r. He has a B18c not a D16.

red eg your setup is fine. Run E85 especially if you have stations near you. Regardless just tune it like it's running E70. Up to 400-450whp you would probably not need any advance timing anyways to make your power goals. The only thing in you list I don't like is the turbo manifold. A SPA manifold would be a step up as the runners enter the collector smoother.

mechanix619

The only downside is that it takes more fuel to make the power so the cost per gallon sort of levels out with pump gas.

OP, you may need larger injectors. The 1,000cc should be fine but you'd be taking them to the max flow rate. I'd suggest stepping up two sizes in order to gain some wiggle room.

Typically for your power goal 750cc would be the ideal size but E85 has a different stoiciometric fuel ratio compared to pump gas; 10.0 versus 14.7 respectively.

You'd need an injector that flows 104Lb/Hr versus 71Lb/Hr; a 1,000cc injector flows about 101Lb/Hr.

Just some food for thought.

Doesnt alcholol just dry things out overtime? My tuner always said running E85 isn't just running bigger injectors and fuel pump.

mechanix619

I think its the same as pump gas, run cleaner every so often. I use Lucas every other tank of gas.

VtecCarHauler

Yes, it does take more fuel to make the same power as gasoline. What makes Ethanol so attractive besides price is that it has cooling properties not found in other race fuels. If you think of it the whole point of using race fuels with higher octane is to control the timing of the combustion happening in our engines. Even if you are not using the E85 to it's potential the comfort of having added safety outweighs cost if there even is any. Many ppl have near the same mpg as 93 octane on a n/a or turbo honda running e85. The b-series engine is one of the most efficient engines so with good street tune the mpg wont be as bad as most would think. 1000cc injectors with the walbro intank will support 300-400 or even higher depending on the efficiency of your setup. Run a thicker than stock gauge power wire to the fuel pump on a relay for more fuel pressure.

Best thing to do is ask ppl who actually run e85 as the negative criticism comes from those who do not even run e85 in a race car or daily driver or may have had bad experience due to other reasons besides the fuel.

the red eg

Vtec I don't like the manifold either. I bought the car already swapped the person I purchased the car from had a turbo kit never installed. I got the turbo, fmic, manifold, junk wastegate and bov and rc440cc for $200. Have been looking into different manifold just not sure wich 1 to go with.

I am aware that e85 uses 30-40% more fuel but if its safer and makes more power I don't care. My tuner uses e85 in his cars so I will talk to him some more, just wanted some opinions from more people.

It's the same as pump gas
Pump gas is oil base
E85 is corn base

TKERacer619

Go for it.

ID1000s will flow more then 1000cc given you run them at a higher psi. the 1000cc is at ~58psi and something like 1300cc at 100psi iirc.

I only have a few stations closest one being 15 minutes away but its still worth it to me.

Hope you like french fries. Your exhaust will smell like them!

Your power goals are reasonable. Your fuel system is more then enough. E85 Is great. I use to pay $100 for 5 gallons of race gas now I pay $15.

the red eg

If I had to run race gas only I would be screwed. I have access to e85 within 5 minutes.
I guess I will need to get a map sensor cause I think it will take more than 10lbs to make what I want

300hp does not need e85... You can make that on pump while getting more.miles to a tank

Remember e85 is cheaper but because it requires more fuel vs. Pump (e10) for a given power level you get less distance per tank...

While 350is lolol on a stock bottom end you could probably get 300 if your tuner is really good but just stick to pump gas

the red eg

I know my goals do not require e85 but where I live 90% of gas stations only have 91 the other 10% has 90 so no 93 octane for me. Don't know how much of a difference it would make 93 vs 91.

Very well put!!! you were much more concise than the way I would have written it.
