im going to be running E85 in my Turbo car. but i wanted to run pure Meth in my all motor car to have as much power as possible, but i have no experience with this.

about how much power is gained with meth over C16 in an NA situation?

i know its VERY corrosive, so are there meth specific lines, fitting, pumps out there?

anyone have links for good info on converting to pure meth so i can read up?

 

I’m doing a methanol build on my turbo FD. I not know about the turning side of things but you can use the Goodridge 811 or 910 PTFE hoses which are methanol compatible and SX performance do pumps which are compatible. Your hose ends and fittings will also have to be hard anodised or stainless if you can find them to be able to cope with the methanol. Fuel tank is also a concern as most are made from plastic or aluminium, iv had mine made out of stainless steel to cope for longer periods of time but you must be careful as methanol vapour can build up in the tank which is very dangerous a spark from the batter or static from the filler hose could set it off.

Im askin so we can check out ideas !!

its TIME we stepped up !

 

i havnt heard of and rotary guys running Nitro. pure meth on a few, but not nitro...

but im looking for added benefits. im trying to choose my fuel for my all motor drag car. im stuck between C16, E85, and pure Meth.

im pretty sure meth would make the most power. but im unsure of injector size, fuel capacity needed, ect...

 

from what i've read, the acidic byproducts of methanol can chew up an engine. does anyone know what has to be done to protect rotors and the sealing surfaces? i also read that additives can neutralize the acids, but i haven't been able to find what additives do so.

for all you chemistry majors out there, can you post a reaction formula to show what acids come from methanol combustion?

 

The only guys I know that run methanol run a dual fuel system.(drag racers, piston engines) They start and warm up the engine on gas, switch for the run, and switch back before shutting down. The 560cu.in. big blocks they run won't heat up on the methanol, sounds perfect for a rotary.

I know a few guys that used to be involved in the CART series as well, they had to run the alky out of the fuel systems as well at the end of the day with gas.

 

seems like a lot of trouble for a regular guy like myself. I think i am just going to try E85, and if it dosnt yield the numbers im looking for NA, then i'll just go with C16...

 

Ive been wondering about the benefits of E85 on an N/A rotary application myself. I had even posted a thread on it in the N/A section a while ago, but got no response. It sucks we are limited to 9.7:1 (or 10:1 if using Rx8 rotors) compression ratios, whereas in piston application you have as many choices as you want.. so our only way of making more power N/A is through timing and RPM. I would think that because of the lower combustion temps of E85 as well as higher octane, we could become very aggressive with fuel and timing, but as to what degree I have no idea. Im going N/A 20b in my FD, and although it will still be a street car, Id love to be able to squeeze every drop of power out of it that I can, reliably.

 

I bet you would lose power going to methanol in an n/a rx-7...

 

I was thinking that too. Although I dont have alot of experience in tuning myself, I recall reading articles about mazda using even lower octane rated fuels in their N/A racing applications, due to the way combustion takes place in a rotary.

 

i would have to disagree. I just recently found out a few of the fastest NA rotaries in the world run on meth...

it just seems like to much of a hassle unless your trying to break records or compete professionally. but because im curious, why do you think it would lose power?

 

Isnt the Furai's N/A 3-rotor run on E85? Maybe someone who is close with the guys building engines at racingbeat can get us some info on what they think, or did differently for that engine to run so well.

 

No, they used E100. wich is pure Ethanol. E85 is 85% Ethanol and 15% pump gas.

 

I always have drums of methanol around for making biodiesel. I may get crazy some time when I go to the dyno. I'm going to ask my piston guys what to look out for with gaskets and stuff. IIRC they've said they pick up about 100-150hp on a built big block chevy. Its a jump from 700 to 800+ hp on the mild ones.

 

damn... 100-150 hp is a damn big jump from switching fuel. but they need meth when running 14:1 compression or higher... i wonder if meth would give us rotary guys the same advantage?

the few people i know of that are running meth, arnt giving up secrets about it...

hopefully you go through with it and do some dyno comparisons and report back here.

 

E85 works very well in both turbo and non turbo applications. It ***** all over c16. Its very close to methanol.

 

hey about the gas tank and volatile vapors just apply the same technology used in old wwII fighter planes solid tank outside with a rubber bladder that lines the inside and closes as the gas level drops eliminating the build up of vapors.
