Re: stright Alki.?

Methanol is very corrosive on certain metals, you have to watch out for using the correct metals in your fuel system.
Plus methanol is a fire hazard running pure methnol under your hood, you cannot see it when it is on fire.

Really? Ok I will admit Im wrong on this one then. But there are plenty of cars that run 8's without E85. Im just trying to understand WHY :D

i would imagine it would be cheaper than it equivelent in race fuel, cool intake/engine temps.

Re: stright Alki.?

I guess we never answered sy1219's question. I turned it into an E85 post.
I have never heard of anyone using 100% methanol as fuel. I have heard of guys adding it to a full tank of gas. I guess it helps.

Re: stright Alki.?

Methanol is alcohol as in a car that runs (alcohol) is methanol. You use it on a normally aspirated engine if you are about 15:1 or above for your compression ratio
Most race cars in Brazil use Methanol because there regular car fuel sucks.

It'd work fine... better than fine, in fact.

It would require lots of tuning. And, you have to have a stout fuel system capacity-wise to make it work.

The "corrosion" is old wives tales. Any rubber components made in the last 20 years are 100% alcohol compatible. Water is the cause of any corrosion claims related to alcohol.

Look at Top fuel, TAD. Both use methanol as a base fuel. If gas was better, wouldn't they use that?
Same with CART, before they started using E85 recently.

Methanol is nasty stuff to handle, and burns invisibly. E85 doesn't have these issues.

Several of the top power makers at Car Craft's Dyno contest this year were E85 burners.

OK I better elaborate. I never heard of a Sy or Ty running pure alcohol/methanol.

Maybe I need to change my mind about E85. Sounds like it makes big power for most people.

Re: stright Alki.?

From the past two years of E85 dyno experience, I'd day its more like 105 octane. You use a lot more of it and in the end, while it may be cheaper than pump premium with near race gas performance. Your mpg suffers and even with the cost savings factored in, you might not be ahead using E85 over another higher octance fuel. It also degrades the motor oil quit a bit faster. Not to mention fuel components on the car that fail even when rated for alky or meth use.

Re: stright Alki.?

your 93 octane is 2.85? and e85 is 2.99? My 91 is near 3.89. if you are correct, then i live in the wrong state

Ok what all would need to be changed to run stright Alki.?

3 times the injectors, a fp that handles that much more volume, and basically you need to overhaul your entire fuel system, from the feed lines, the filter, the rail, and maybe even the return line. On my dsm I am doing stainless alky safe filter, fuel rail, twin 255's 1150cc and all braided lines to the motor. and the 1150's will support about 400hp on e85.

Re: stright Alki.?

ethyl alky and methanol are two different monsters. Just for Sh*ts and giggles I was looking into running pure meth (well at least in theory since im not made of $$$$). Meth has a higher Octaine raiting than ethyl alky and you can run nasty boost (30+ without an intercooler)- however it is really nasty to handle. You have to wear gloves and a bunch of other stuff as it converts to Formaldehyde in your body and is absorbed through the skin. Granted, I would still love to do it.

Ethyl Alky would be far friendlier to play with and you could in theory make your own at home. You can even apply for a permit with the ATF to have your own private still for automotive usage. Not saying you would be granted the permit and there is all kinds of rules and regs. Im just offering the legit route.

Both can react with some metals and corrode but Ethyl is the kinder of the two.

Meth would in all reality be for pure race only. In one of the import mags a couple years back they had this mega sleeper hundai or honda (some p.o.s.) that was running two turbo charged engines. The back windows were painted so you couldnt see the engine in the back. Had no intercooler on either one as the guy was running pure meth. Apparently he was running low 10's all day. didnt handle for sh*t but was smoked many a folks in a straght line (and isnt that what we are here for....).

Re: stright Alki.?

If I had the $$$$$ I would run a duel fuel system. I'd have alky/meth in a seperate tank with its own fuel system and i'd have an intake with dual injector bungs. So the gas would run on one set and when you switched it over to alky it would use both sets (as you would have to increase the amount of fuel). Plumbing and engine management might be a nightmare but hey its only $$$$$.....

Plus it would look crazy :)
