What octane is racing methanol?

The square yellow octane stickers you see on gasoline dispensers indicate the (R+M)/2 octane rating. BOVs for methanol and ethanol typically overstate octane.

Does Sunoco make methanol?

The Sunoco racing methanol is produced to the highest possible standards. Its purity normally exceeds 99.85%. Methanol’s high octane value and oxygen content (50%) make it a popular fuel….ALKY Methanol top lube.

Is denatured alcohol methanol?

Denatured alcohol, or methylated spirits, is just alcohol with some stuff added to it to make it bitter and dangerous to consume — primarily methanol, but also often isopropyl alcohol (which is dangerous to consume in any quantity), acetone, ketones and other toxic chemicals.

Is Sunoco Ultra 93 good?

Whether you fill up with Regular (87 octane), Plus (89 octane), Premium (91 octane), or Ultra® 93 grade of fuel, rest assured you’re getting the very best at your local Sunoco gas station.

Does Sunoco 93 octane contain ethanol?

Sunoco Optima is an unleaded fuel blended from highly-refined hydrocarbon blendstocks. Optima does not contain ethanol or MTBE and is oxygenate-free.

How do I use methanol in a drag racing application?

I will be running a carbied 308 Holden small block V8, and am wondering if using methanol or another type of alcohol based fuel is more advantageous than say Avgas or Pump fuel. The motor is stock stroke, about 10-5:1 comp, has some large head work done and a good cam (stage 4 I’m told).

What is the purity of M1 racing methanol?

M1 Racing Methanol has a 99.95% minimum purity – the highest purity available in the U.S. Compared to standard methanols, M1 engines run cooler and are less subject to corrosion. VP uses only lined drums which prohibit rust, corrosion and metal deposits that can contaminate fuel delivery systems.

What’s the correct AFR for a methanol wideband?

Im a little confused about the correct afr using methanol and the different target that i supposed to have on the idle, mid and power range… im using a methanol wideband that reads from 3.75 to 7.0 afr… Lambda 1 for methanol is 6.4 (Andre can you confirm ?)

Is there a Lambda limit for methanol fuel?

In fact the rich limit of methanol fuel is often enforced by the ignition system failing to ignite the fuel/air charge. This is unlike petrol where we will see a sharp drop off in power once we move richer than perhaps 0.75 lambda or thereabouts.
