No fuel flow restriction exists in the IndyCar Series engine configuration.
Why do Indy cars run on methanol?
Internal combustion engine fuel
Using methanol as a fuel in spark-ignition engines can offer increased thermal efficiency and increased power output (as compared to gasoline) due to its high octane rating (114) and high heat of vaporization.

Both are safe to use in small amounts, but uncontrolled and unregulated mixing can result in concentrations high enough to cause additional wear and damage over time to sensitive gaskets and hoses in the fuel system. In the future, there may be a place for methanol in our fuel supply.
Can I run my car on methanol?

Do Indy cars still use methanol?
That’s what you filled your gas tank with this week. With its biggest race, the Indy 500, in the Midwest farm belt and manufacturers in the Iraq war limelight, IndyCar quickly shifted from natural gas-based methanol to pure corn ethanol in 2007.
What octane is jet fuel?
The octane ratings of AVGAS, a gasoline-based fuel, are usually either 91 or 100 (lean mixture) and 96 or 130 (rich mixture). The octane rating of jet fuel is much lower, around 15 – this is much more like automotive diesel and thus much more resistant to detonating due to sparks or compression.
