Race Gas

  • $53.95 CAD

Makes 108-112 High Octane Gas

RACE-GAS ULTRA is specifically designed for the requirements of very high compression, boosted or nitrous engines. ULTRA, when mixed with pump gasoline, will create racing fuel with octane between 108 and 112 r+m/2. Like our original product, ULTRA increases the octane, chemical oxygen and chemical energy of the fuel to equal commercially distilled racing fuel.

RACE-GAS ULTRA is a much different formula than original RACE-GAS. “In testing, we found the requirements of very high compression engines were different than engines with lower compression or lower boost. We needed to create a formula that could achieve the high octane while still meeting our requirements of high chemical energy and high chemical oxygen in a consistent and predictable way. We chose to use the highest quality pharmaceutical grade chemicals and to avoid using alcohols or naphthalene which don’t meet our design standards” said Dan Muldowney.

“Further, when we did our engine dyno testing we did “like for like” testing against commercial racing fuel. We first did a series of “pulls” with commercial racing fuel. We then drained the fuel and fuel rail and added RACE-GAS ULTRA blended with pump gas. We then repeated the test. We did not change the engine set up or tune during testing”

“We found that we were able to create the same horsepower and torque as commercial racing fuel and that the fuel performed consistently under different conditions.”

1 Can RACE-GAS ULTRA + 4 gallons of 89 = 4 gallons of 108 Octane R+M/2

1 Can RACE-GAS ULTRA + 4 gallons of 91 = 4 gallons of 110 Octane R+M/2

1 Can RACE-GAS ULTRA + 4 gallons of 93 = 4 gallons of 112 Octane R+M/2 

Try a can of RACE GAS ULTRA and you'll find what everyone is finding - that RACEGAS really works, turning ordinary pump fuel into RACE GAS. Visit for their Blending Guide.
