hey guys searched for this and cant find anything but methanol injection and stuff on turbo cars. What i want to know is what kind of gains besides more timing im going to get out of switching. This is NOT a street car so frequent oil changes and all that stuff isnt a problem. I just want to know a ball park figure of a power increase because i know a 50 hp increase on turbo isnt uncommon but what about all motor? ill list engine mods if i need too but its all built and and running high 11s on pump gas with additive, this is the car (red hatch) http://youtube.com/watch?v=w_GdnHGqUno before intake and TB and new tune and possibly methonal and 100 pounds heavier

 

at high 11s, you probably arent at the limits of pump gas yet, why switch now?

 

That's a hard question to give a definitive answer to because you'll want to increase your compression to get the most out of the methanol, so some of the gain will be due to the increased compression, not just the fuel.

Hypothetically, if you were running a 12.5 or 13:1 N.A. engine on race gas, you may see a 10-15% peak increase by running methanol, peak HP & TQ will move lower in the rev range (maybe 1000 RPM lower), and you'll lose RPM on the top end from the doubling the volume of fuel.

If I was building an alcohol engine, I'd run way higher compression (17+:1, at least 14:1), change cam(s), and buy a gas mask.

 

its got 14:1 now, and why change now becuse methonal is way cheaper and if it gets more power then why use gas

 

your car will run cooler and more consistant if you switch.

 

ok thanks thats more towards the stuff im looking for but does anyone have any indea in power difference in a all motor car with it

 

ya, methanol is cheaper, but it runs at 4 or 5:1 AFR's, so you run a ton more fuel. so the price evens out. the gains are crazy though if tuned right.
