What is the mixing ratio for methanol and pump fuel?

I'm running a stock 400ex engine- should I be able to feel any change in power with race fuel?

Thanks

Your waisting your money on race fuel on a stock engine. Any change in power will be minor. If your intent on running race fuel mix it 50/50, but you don't need it.

Are you sure it's 50/50? I got this stuff from my buddy who works in a chemical plant. He told me mix it 6:1 meaning pumpfuel:methanol.

My advise to you is to not use it, what little power you gain is not noticeable, and you risk damage to your engine. A stock engine does not need race fuel. Also do you know the octane of the fuel and are you sure it is race gas, because if is not you could blow up your engine.[img]i/expressions/face-icon-small-shocked.gif[/img]

I think you're confused....

Normal race fuel and methanol are two very different things.

Also wanted to mention that you don't risk "blowing up your engine" by using it in an engine that doesn't require it. That is a very widely held misconception.

You simply end up paying more for fuel than you need to.

OK- Here's the deal

Race fuel IS methanol. I know what I'm talking about. I can get alot of this stuff for cheap and I've heard many people use this in their stock engines... especially in High altitude areas. I'm in Utah and at 5500 feet.

...and NO- it won't blow up an engine


...and I still havnen't had my question answered yet. Everyone thinks they know about RACE FUEL- and offer suggestions to NOT use it- however- nobody has the knowledge of how to mixi it. So my question to you is-

WHAT IS THE MIXING RATIO?

I'm running 92 octane. I'm not looking for massive power gains- just more throttle response (which I have already have found using this stuff).What is the Mixing Ratio?

You need to do a little more research.

Methanol is typically referred to as "Alcohol" not "Race Fuel". The term race fuel typically refers to high octane gasoline. Really a semantics issue...

Indy cars do use this as a fuel because of safety & the high compression ratio's they run. Methanol fires can be extinguished with water. It's also used in drag racing, and a few other forms of racing.

There's a few factors you need to consider if you are considering methanol as a fuel.

First of all, it's a fairly powerful poison & requires special handling. Make sure to research this if you intend to follow thru with using methanol.

It takes more methanol than gasoline per unit air to obtain the correct mixture. This means richer jetting, or YES you can cause engine damage. The correct mixture for Methanol is generally from 7:1 to 9:1 where gasoline is typically 12.5:1 to 15:1.

Since you are going to use roughly double, your fuel delivery system will have to be able to keep up. This means hoses, petcocks, float valves, etc...

It attracts moisture.

Methanol can also attack rubber seals & o-rings.

Also to obtain any benefit, your engine has to be built to use it's advantages -- ie high compression. The ignition timing will also have to be altered due to the different burn rate.

That said, there is no "correct" mix ratio... There is a correct engine & carburetion setup for an intended mix ratio.

My suggestion - unless you REALLY know what you're doing & have reasons for doing so, forget about methanol.
