PTT's reverse starter mount bellhousing has set a new standard for lightness. The aluminum bellhousing weighs a mere 9 pounds! This bellhousing is intended to be used with lightweight button-style flywheels and a starter ring gear mounted on top of the clutch. There are a number of advantages to using a reverse mount bellhousing. The starter is mounted away from the heat of the headers. The small diameter flywheel and clutch allow the drivetrain to be mounted lower in the chassis. The smaller overall physical size of the bellhousing is more easily packaged in a stock car. Relocating the starter lowers the vehicle's polar moment of inertia resulting in better handling and faster turn-in response.
