Honda's IRL engines will get bigger with switch to ethanol
To keep the Indy Racing League cars from slowing down next year when the teams are forced to use ethanol, Honda will build a bigger engine for the series.
Currrently all IRL V8 engines are 3.0-liters. Next year the maximum displacement will be 3.5-liters.
According to IRL-live.com, the bigger engines will give the cars more torque at low-rpm ranges and help improve durability. By running the engines at a lower rpm, Honda can save up to $400,000 with fewer rebuilds between races. The biggest reason for the change, however, is that the horsepower output with ethanol will be lower than the current methanol formula.
