gallardo twin turbo specifics
The following is copy of text Heffner released to a Magazine
doing an article on the car: Engine: The engine was removed from the car and completely disassembled. The factory design has the pistons riding on aluminum cylinder walls with a Nicosil coating. We had steel sleeves designed for the block, bored out the block and installed the steel liners. The cylinder walls were then torque plate honed to size. The factory pistons were replaced with dished units to lower the engine's compression ratio. The connecting rods were checked for straightness and the small ends were honed to properly fit the new wrist pins. The crankshaft journals were micropolished. The entire rotating assembly was then balanced. Next, the engine was fully blueprinted and assembled. Clutch: Wayne contracted Tilton Engineering to build a custom four disc carbon clutch and steel flywheel. Turbo system: We designed the custom turbo system out of 32 stainless steel for the hot parts and aluminum for the air charge piping. We used a pair of Turbonetics T61 ball bearing turbos, Spearco Water to air intercoolers, Tial 38mm wastegates and Tial 50mm blow off valves. The exhaust system has also been fabricated out of 321 stainless steel and is specific to this turbo system. Engine management: There's not a whole lot that I really want to say about that. I would just say that fuel and spark management was handled via proprietary Heffner Performance engine management. Performance: All we have at this time are dyno numbers. The car in stock trim put out 418 hp to the rear wheels which is just shy of 500 hp. With turbos the car put out 679 to the wheels which is right at 800 hp. |
