Twin high pressure bottles contain CO2 gas, one bottle powers an experimental air shift system. The air shifter goes along with an ECU controlled shift system for a dog gear set in the stock transmission case. The air shifter is still under development and was not used for this event. The other CO2 bottle supplies pressure to the twin 66mm Precision Turbo wastegates. The boost pressures are so high that the intake manifold does not have enough reference pressure to keep the wastegates from blowing open so regulated CO2 must be used.
Twin Accufab75mm throttle bodies are needed to feed the monstrous motor. The 5.4 liter modular motor is kept at the stock displacement. It uses forged JE pistons with a you gotta be kidding me 13:1 compression ratio. The pistons are hung on custom Accufab spec Manley rods. A custom Accufab spec billet Bryant crank shaft helps harness all that combustion pressure.To keep the 45 psi of boost at 13:1 compression inside the motor, the block and head are cut with receiver grooves for gas filled O-rings backed by a solid copper head gasket. The head and block bolt holes are drilled out and retapped to accept larger ARP studs.
All structural fasteners within the engine including the main cap bolts are replaced with high strength ARP studs. The cylinder heads are CNC ported and are fitted with larger valves, stainless steel on the intake and Inconel on the exhaust side. Comp Cams are used, 4 of them in all with the rest of the valvetrain relying on Comp Cams for motion control. Surprisingly the radiator and oil cooler are the stock factory parts which probably speaks a lot for the cooling effect of methanol as fuel! In fact, the life of the engine depends on methanol's high latent heat of vaporization to stay alive during the long run down the mile.
A tried and true MoTeC M800 tuned by Naoto Negishi of Negishi Competition Systems handles engine management duty with a MoTeC CD8 CDI unit handling the task of ignition. With sky high cylinder pressures caused by a 13:1 compression ratio on top of 45 psi of boost and methanol fuel, a super powerful ignition system is critical. Naoto tunes the critical traction control and antilag features of the MoTeC as well.Wiring and plumbing issues traditionally cause 80% of racecar failures. The folks at M2K Motorsports have done a great job with keeping the wiring sanitary with a logical layout that helps avoid problems and facilitates troubleshooting.
John Mihovetz of Accufab Racing Engines is the the engine builder behind this car's amazing power levels. Although we can give you the basic specs, a lot of the engine's internals and what keeps it alive at these power levels are closely guarded secrets. 
When you start off with a supercar you are often times paying for more race oriented and less compromised hardware and engineering from the factory. Your typical street car is designed to be cheap and reliable at highway speed whereas a supercar is designed for much higher speeds stock. With supercar underpinnings the M2K Motorsports car is amazingly stock except for the super engine! The front suspension is totally stock with the exception of some 4 way adjustable Ohlins dampers.
