ATI‘s new bolt-together, lock-up torque converter fills a long-time gap in the company’s catalog, but the wait will be worth it for high-torque applications like diesel pullers.
“It’s a first for us,” says ATI president JC Beattie. “The big thing is, it’s only a pound and half heavier than our old lock up, but it’s good for 500 percent more holding capacity.
Constructed of half billet aluminum and half steel, the 10.5-inch diameter torque converter is capable of supporting just under 5,200 lb-ft of torque.
“We offer a half dozen stators for it, so it can be configured for a variety of applications,” adds Beattie.
The torque converter is designed for use with existing lockup transmissions, such as the ATI 2- or 3-speed Turbo 400. It operates with a single 12-volt connection to fire the lock-up solenoid.
“We lock it up with line pressure, which is typically 275 to 300 psi,” says Beattie. “Some guys run it on a timer and some are rpm in high. You can trigger it through your EFI or MSD box, there are a lot of different ways.”
ATI has some half dozen different stators that can be used with the torque converter, allowing technicians to set it up for specific applications since each is hand-built in house.
ATI also showed off a new Super Damper that will fit the 2016 Camaro SS and the CTS-V. This damper now completes all the current LT1 and LT4 applications for Camaro, Corvette and Cadillac, including wet- and dry-sump motors. Just as other Super Dampers, it’s SFI approved and features a billet aluminum sheel and steel hub. It will work with OEM or aftermarket overdrive pulleys.
