Looking for more power from your Hellcat? Earlier this year, ATI Performance Products, Inc., unveiled the first direct bolt on Hellcat Super Damper in OEM diameter – part #918483. Now ATI is proud to introduce its all-new 10% Overdriven Super Damper (Part # 918485) for the 2015+ HEMI Hellcat 6.2L Supercharged engine. The new 8.9” diameter, 2024 Billet Aluminum-shell damper with a steel hub, increases boost by 3 psi and with custom tuning has yielded 60 more HP at the rear tires using 93 octane pump gas, and even more on E85. The ATI Super Damper is better capable of handling a wider variety of driving habits that Hellcat owners will put their new cars through, especially with the added HP! OEM dampers are optimally tuned to a narrow band of perceived normal driving conditions and do not perform well outside of those limits. The ATI Super Damper can handle any engine speeds and driving conditions that get thrown at it to better protect your engine. ATI Super Dampers provide balanced dampening of torsional crankshaft vibrations through all RPM ranges and exceed SFI 18.1 Safety Certification for competition use.
ATI Performance Products, Inc. is located in Baltimore, MD, and specializes in producing and maintaining high performance products for street and strip applications. Over the years ATI has earned a reputation for its cutting edge technology, attention to detail, and rigorous testing under race conditions.
The patented ATI Super Damper is the only crankshaft damper designed exclusively for high performance Chrysler, Dodge and Mopar Engines - including the new HEMI!
