Frequently Asked Questions

How much boost increase can I expect with 20% overdrive?

On most centrifugal or positive-displacement superchargers, you can expect approximately a 2–3 psi gain depending on setup and pulley configuration.

Do I need a custom tune after installing this damper?

Yes. Increasing blower speed alters airflow and boost pressure, so an updated tune is required to maintain safe and optimal performance.

Can this be used with stock belt systems?

Yes. It fits factory 8-rib accessory layouts on the 4.6L Modular while adding overdrive benefits.

Is it suitable for naturally aspirated engines?

While it will still provide superior harmonic control, the overdrive benefits are designed for forced-induction setups running superchargers.
