tuning of methanol

[ivanovbg]

I plan to install additional large injectors for methanol.
You can work and petrol.
I do so:
1.octane plug 95-AFR-normal petrol-14, 7 ;Spark advance 95-petrol
octane plug 98- AFR -6,4 ;Spark advancе 98-methanol
If tables are 95.98 AFR petrol will have to switc -octane plug with relay
2.if I happen to do a double EPROM for gasoline and methanol,or two computers with the same sensors.

will try this first bin

100% gas.......................14.7
90% gas, 10% meth.......13.87
80% gas, 20% meth.......13.04
70% gas, 30% meth.......12.21
60% gas, 40% meth.......11.38
50% gas, 50% meth.......10.55
40% gas, 60% meth.......9.72
30% gas, 70% meth.......8.89
20% gas, 80% meth.......8.06
10% gas, 90% meth.......7.23
100% meth.....................6.4
I think and try different mixtures
You and I put a little oil that washed the cylinders when cold

are you planning to mix the methanol in the tank or as its fed into the engine ?

i didn't know you were planning to run a mix, i thought you were using straight methanol.

[ivanovbg]

I finished. Perfect happened to mix 20% petro and methanol 80% -167 horsepower for stock 100.Compression-15.7/1
Thanks to all

15.7:1 ... how are you managing that ? i didn't even think you could run that much compression with straight methanol!!

The most compression I ever saw was in the USA at Cosworth Indy engine plant, They built a YBV 2.1lt 4cylinder with 21.1 compression on methanol and direct fire ignition and put out 340hp at 10,000 rpm N/A but was stuffed after 40 lap midget race, I know I pulled down the the long block assembly to find ceramic coated pistons and chambers then I had to put it all in the bin, Wish I was allowed to keep a piston and rod. This was in the 90s when Cosworth turbo v8s were winning Indy car. We did win the midget race.
you don't get nothing for nothing now days.

well my understanding is the bigger your cam is the more compression you can have as its half going out the exhaust anyways .... so for a mostly stock car you might only able to run 13:1 but for a full house race motor you could have 15:1 etc .....

but i guess things like alloy heads and such all change the equation too.
