In development for some time, the new Whipple Industries supercharger kits for out-of-warranty, 430-hp MerCruiser 8.2L Mag HO ECT engines should be ready next week. That’s the word from Dustin Whipple of the Fresno, Calif., supercharger and supercharger kit outfit.
With a 3.3-liter Whipple supercharger and other kit-supplied accessories including a new intake manifold, the 8.2L engine should produce approximately 600 hp, according to Whipple. Buyers of the kit will need to ship their stock electronic control units to Whipple for reprogramming.
“This kit has been a work in progress,” Whipple said. “But we’re almost finished with it.”
After Whipple’s work on the 8.2L upgrade package is complete, the company will focus on completing its kit for the popular MerCruiser 350 Magnum ECT small-block engine.
“We wanted to finish the 8.2 kit first because that’s more of our core customer,” Whipple said.
With a 2.3-liter blower and the other Whipple-supplied accessories, the kit will boost the 5.7-liter engine’s output from 300 hp to approximately 465 hp. As with the kit for the larger-displacement engine, buyers for the 350 Mag ECT package will have to send their ECUs to Whipple for recalibration.
Retail cost for the 8.2L kit will be $7,000 to $8,000. The kit for the 350 Magnum kit will retail for $6,000 to $7,000. (Final pricing has yet to be determined.)
