so I have a few choices and i want to know what you guys think. I have e85 available to me but i think my fuel economy would be so poor I couldnt ever go any where considering on any given saturday night i drive up to 150-190 miles, obviously with that in mind It could be difficult to go drive around race a few people then drive home. however i dont mind keeping a 55 drum or two at the house to keep me topped off. but im still not sure i could ever really get on the gas because i would never be able to get home before i ran out of gas.
AI seems great but I doubt through auxillary injection I can reach the same power levels as I could with only e85. which is why i question it.

 

subd

 

what power levels are you looking for...?

i myself would rather run E85 with AI also... have the best of both worlds, but if your looking for good gas milage and power. Maybe rotary isnt the way for you...

cheap, realiable, fast.... you can only choose two.

 

i know not very many people will agree that these power levels are driveable but 800 or more we have some 1000hp+ supras that are running around here that i want to run down on the highway.

Im using a 20b with a t88h with balanced low compression rotors to within a 1/10th of a gram race ported, dowel pinned yatta yatta yatta a t88h 4 inch all the way back gutted car with 335 tires in the rear

 

335?
I make more then 600 hp pump gas in my fully built rb25 powered s14 and all I use is 275 MT
same as Titan and most here in orlando.

Methanol is the way to go.But e85 is way better if you actually have one of the best tuners out there who can actually fine tune your car for e85
Not talking about kids with a laptop jerking of on **** here.lol.
A good certified tuner.

 

600hp with a fully built rb25 is not difficult getting 600whp with a 20b is a bit more difficult

I dont allow anyone to touch my tuning other than Chris Ott from rotary performance I dont half *** my car in anyway. im not going to use mickey thompsons im not a fan of drag radials plus it really cant hurt to have 335 tires there is no thing as too much traction.

why is methanol the way to go but e85 is way better????
what kind of power numbers are possible with a 100%meth AI?
is e85 going to make more power?

 

No offense but throw your turbo in the bin.

Go get a Gt47r88 1.01 rear.

Put Water injection on it and run around 26-27psi. 1000rwhp is possible if the tuner knows what he is doing.

E85 is great.But your not going to carry drums of ethanol around with you

 

You also need to change your oil about every 10 run hours with E85 due to oil contamination.

 

The problem with E85 is its availability. It's the only thing that kept me from doing an E85 conversion on my car. There's only two E85 stations in my county. I used to do the full time racegas thing too, I have a 55 gallon drum and a pump. But I just got tired of the inconvenience.

 

You are going to find a million different answers to your question. You should be asking Chris; after all he is the one doing the tuning. Everyone has their own way of doing things. Personally I would blend a few gallons of race gas, and run water/alcohol injection...

 

where did you hear this, its untrue ? I know a few people running E85 on daily drivers with no problems at all. You might be confusing E85 problems with pure meth problems. and im not talking AI. im refering to running puer meth as your only fuel supply.

 

what numbers are possible with methanol injection and pump only in your opinions

 

e85 dosnt contaminate oil unless your engine is garbage and has heaps of blow by.

I made 700rwhp on pump fuel with water injection and i only have a 13B and a gt4202.

With a 20B and a GT4788R you will make in excess of 1000rwhp.

 

i love all the bs statements of E85.. It will not contaminate your oil...
It is also fine with fuel economy as well depending on your driving. IF your foot is going to be on it all the time then it doesn't matter what you run as a fuel as it's going to disappear fast...

My opinion is if E85 is readily available in your area then i would run it..

I also agree with rx72 and believe your should run a 4788 turbo.

I would guess you would make 800 rwhp at around 17~20lbs with that turbo on E85.

 

wouldnt the 4788 turbo with low boost be kind of sluggish for street driving. I realize it can be a trade off but I would like to have some level of responsiveness.

enzo 250 what kind of fuel economy would you expect to see with a setup like mine?

 

E85 will only allow you to run more boost with out detonation.But in 17 to 20psi.its just stupid to even think about e85.More like 32lbs + of boost
if not even close to that just run meth and fck e85.
I'm not about drag racing but when you build and fine tune your car you will want to do an 1/8 mile run to see whats your trap speed which will allow you to have an Idea where you at.Performance wise tho.

 

E85 is better in everyway than pump gas. i been looking at some pump gas Vs. E85 back to back comparisons lately for all motor. and E85 makes more HP/torque and has better curves as well...

so even at low boost. E85 is the way to go. adding some water or meth into it can only help. it will not hurt anything...

E85+AI is the way...

 

i know e85 is much better at reducing detonation but could a pump gas car with enough AI be comparable in its ability to reduce detonation except with the added fuel effiency?

 

put it this way, if your really going for 1000whp area. dont even think about fuel economy. wether you use E85, pump, or C16. you will not have good milage.

forget about the milage, and worry about building it safely where you will not blow it up.

 

example... every 400 hp area TII i have had barely get over 10mpg. bridge port NA's barely get over 12-13mpg.

if you want milage and big power. get a corvette. othan than that, just drop it...

 

Drop it??? Hell why dont we just close the forums and say that there is nothing more to do to our cars and just call it done. I'm not interested in a corvette im up to around 40k or more in 20b project just for the drivetrain and ecu I have no plans of buying a vette or dropping it.

now back to my question could AI ever drop detonation levels as far as e85?

 

didnt mean to offend you homie...

i was just trying to get the point accross about the milage issue. theres no such thing as 1000 hp and good milage. dosnt matter what fuel you use. especially in a thristy rotary... and what i meant by drop it was, drop the gas milage thing. not the car.

 

oh its cool man I didnt mean to be offensive either but Ive never been able to quit on something that i was determined to do. as far as 800whp do you think that AI and 93 or 101 would be up to the task or i would i need to just go e85 for those power levels.

 

93 and AI with a 20b is very doable. a little rougher with a 13b, but still doable.

you can reach 800 with pump and AI. and you can reach it with E85. both are a good choice. but i like running a 50/50 water meth mix along with E85. but i also like running higher compression rotors with that... so i might need it.

if you have gas stations with E85 in your area, do ti. but if you have to drive 30 minutes just to fill up, i dont think i would do it.

you have any pics of your car/set up? what style porting is done?

 

I would love to just go e85 its much easier to tune than AI but its just not doable considering it is 16 miles from my house to the nearest station so 32 miles there and back. not to mention I'm guessing at best 6-7 mpg with a 20 gallon tank that is 120-140 on one tank that is just not reasonable in my opinion. maybe when they start offering e85 at more stations in my area.
