What is the difference between the Pump Fuel & Race Fuel Option?

Depending on your application we offer two great engine package options to suit!

Option 1. Pump Fuel (ITB427-1)

This option is designed for street cars wanting to run normal pump fuel such as pump 98 etc. These are a more versatile option depending on your use.

This package is built with a flat top piston to achieve a compression ratio designed to maximize this fuel type. This provides an engine combo suited for all aspects or road/track use!

Option 2. E85/Race Fuel (ITB427-2)

This option is designed with a higher compression ratio than your average pump fuel will allow. When going to a Dome Top piston we are exceeding the limits of Pump 98 which is only beneficial for Ethanol/E85 or race fuels.

This is typically more suited to race cars or predominantly strip/track cars with less street use due to the fuel economy sacrifice of these types of fuels. Don't care about fuel economy? This is for you!

Increasing compression & switching to these fuels can have significant gains when paired with the right cam & head package.
