PURFUELS ISOBUTANOL (99%) 5 Gallon Pail
Isobutanol is a clear, colorless liquid with a mild, characteristic alcoholic odor. It blends seamlessly with racing fuels and maintains stability across temperature ranges without absorbing moisture from the air—a critical advantage over ethanol-based alternatives. The chemical's low corrosivity and compatibility with standard fuel system materials make it ideal for long-term storage in fuel cells between race weekends.
A key technical advantage is its effect on vapor pressure—isobutanol has a lower vapor pressure than ethanol, which means it contributes less volatility when blended into gasoline. This results in a more stable fuel blend across varying temperatures and atmospheric conditions, reducing the risk of vapor lock in high-heat racing environments while maintaining compliance with fuel volatility regulations
Why Choose 99% Isobutanol Over E85?
While E85 is a popular choice for high-octane performance, 99% Isobutanol offers critical chemical advantages that eliminate the classic headaches of ethanol-blended racing fuels.
1. Significantly Higher Energy Density
-
The Isobutanol Advantage: Isobutanol packs roughly 30% more energy by volume than ethanol.
-
The Racing Benefit: You get a much higher energy content per gallon, resulting in superior fuel economy and a lower volume demand on your fuel delivery system compared to E85.
2. Drastically Lower Fuel Consumption
-
The Isobutanol Advantage: Isobutanol operates at a much leaner stoichiometric Air-Fuel Ratio (AFR) than E85 (closer to standard gasoline).
-
The Racing Benefit: You burn less fuel per lap. This allows for reduced vehicle weight (smaller fuel cell required) and fewer pit stops during endurance racing.
3. Zero Moisture Attraction (Non-Hygroscopic)
-
The Isobutanol Advantage: Unlike ethanol, which aggressively absorbs water from the air, Isobutanol does not pull moisture into the fuel system.
-
The Racing Benefit: Eliminates the risk of phase separation, fuel degradation, and tank corrosion during storage. You can leave it in the cell between race weekends without worry. Works in combination with NITROMETHANE.
4. Complete Fuel System Compatibility
-
The Isobutanol Advantage: Isobutanol is far less corrosive than ethanol and behaves similarly to conventional hydrocarbons.
-
The Racing Benefit: It is safe for standard rubber lines, seals, injectors, and aluminum fuel system components that E85 typically degrades over time.
5. Superior Blend Stability
-
The Isobutanol Advantage: Isobutanol easily and permanently mixes with standard racing gasolines without settling.
-
The Racing Benefit: Provides a perfectly uniform blend across all temperatures, ensuring consistent tuning, predictable timing maps, and reliable power delivery.
Summary for Tuners: Isobutanol delivers the high-octane, cool-burning benefits of an oxygenate, but without the massive flow requirements, fuel system corrosion, and water-absorption issues of E85.
