methanol in massey 444

444masseyharris · Apr 20, 2020

i am gonna run my massey 444 with no radiater so i figured since methanol burns colder i can run it is that ok?

Brown Swiss · Apr 20, 2020

Methanol or ethanol, methanol is way more
toxic and really harsh on an engine! I'd
still use a radiator even running ethanol,
unless your just using it for tractor
pulls! If going to run strait ethanol it
should really have a higher compression
ratio than gasoline!

Neither of those fuels can replace a cooling system unless it's for a very intermittent, specific or racing application. The alcohol fuels typically need real high compression to be efficient or worthwhile. Static compression ratios around 14:1 or so, or maybe 10:1 with forced induction. They also need around or more than twice as much fuel as gasoline, most carb or injected engines will either need specific carbs/injectors or modified parts for that much extra fuel.

stoich fuel ratio for gas is 14.7:1, max power about 12.5:1
stoich fuel ratio for methanol abt 6.5:1, max power abt 4:1
stoich fuel ratio for ethanol E100 abt 9:1, max power abt 6.5:1

i am using my tractor for strictly pulling...could i just run no rad at all with regular gas

I don?t have an answer that is helpful to you, but thank you for explaining the use of the tractor, maybe a 2 minute run at a time. Whew at least that makes some sense
then!

I used to drag race, and have many friends that know about what you can get away with. The ones with no cooling system do the burnout, stage, and make the run. Then they shut it off, dump the water in the block and tow back to the pits. Total run time is well under 2 minutes.

what do you mean dump water in the block

David G · Apr 21, 2020

The ONLY reason not to run a radiator when the vehicle is pushed to the starting point, run, shutoff drain, push back to the pit.

Pullers will have more info.

You need very high compression ratios to utilize alcohol, does not matter if ethanol or methanol.

hey would fill the block with cold water before the run and empty it after the run. These are factory style water jacketed blocks just like what is used in street cars.

hat's a common myth. My son and I ran methanol in a junior dragster with less than 8:1 compression. I ran methanol in a 9.7:1 Chevy crate engine, and a 12.5:1 custom built Chevy-style engine.

david G i talked to vp racing fules and they said it should be fine

and got any pics on your efi and how you did it

jm. · Apr 21, 2020

Well I commented on your rpm issue and as I said I built and pulled MH 44s for several years. Only
thing I ever did that worked to some degree was fill the block with concrete. Pull the tractor to
the start and make maybe one or two pulls before heat became an issue. What happens then is you get
two thru pulls and you go back to the line and too hot to pull in the pull-off . Ran automatic
transmission fluid as a coolant for some time and made that work but with a radiator. I do not know
why you are trying to eliminate the radiator. Use an electric fan you can cut the draw or power
loss.

when you say fill the block with concret do you mean in the water jackets?

hope he doesn't mind if I answer this. You can purchase Hard Blok from any racing supply specifically for this purpose. Most people use it to fill the lower portion of the block up to the freeze plugs. YRMV

what good does it do to run automatic trans fluid in rad

dr sportster · Apr 22, 2020

Methanol generally requires higher compression ratios and the carb jet sizes would be double of gasoline jets. The only reason methanol makes more power is because you can dump so much more into the motor BTUs
is less than gasoline. Methanol will increase power about 10%.
