Aero Drivetrain Specs

Katech Engine

Katech takes a GM LS3 crate engine and prepares the intake for reverse configuration, installs Katech rod bolts and a Dailey 3-stage dry sump system. They then ensure that all of the engines have equal performance characteristics by validating them on a dynometer, before applying engine seals to make tampering evident.

The Aero comes equipped with a 6-speed, fully synchronized Graziano transaxle with the same gearing as an Audi R8. The transaxle has a factory limited slip unit, and is designed for a much heavier car with more power, so transaxle life in the Aero should be exemplary. 

With the stock final drive of 3.462, the table below shows the gear ratios and speeds in gears for a 6,600 RPM redline, with a standard 325/30/19 tire or the Hoosier A7 or R7 equivalent.
