In collaboration with Todd Knightion of Protomotive Inc, AR, this 997.1 Turbo was transformed from an already fast 485 bhp stock car to a 1000 whp rocket (@ 28 psi). To acheive such power, the stock 3.6L engine was converted to 3.8L with stronger, state-of-the-art internal motor upgrades, including forged pistons, rods, headstuds, valve springs, E85 fuel system, turbos, GT2 clutch conversion, and much much more. This motor is capable of safely handling 35 psi yet drives like stock. Even grandma would be able to enjoy driving this car, of course with a smile on her face.
