Dai Yoshihara’s Team Falken/Discount Tire 2011 Formula D Ride

Dai Yoshihara's Team Falken/Discount Tire 2011 Formula D Ride
 With top drift cars generating lateral forces of over 1.3 g’s, you typical oiling system ends up getting challenged.  The Accusump is a solid low cost alternative to a dry sump system.  The Accusump is an accumulator that provides oil to the engine’s bearings if the pick up should suck air.  It is cheap insurance to avoid spun bearings.  The Accusump is normally shielded by an aluminum cover but it has been removed for pressure monitoring during testing.

 The engine breathes through a huge 4″ SPD fabricated air intake and a big K&N filter.

 A generous self draining breather tank is used as well as a high mounted coolant surge tank.  The surge tank is overlooked by many amateur car builders and is important as it purges air from the cooling system.  The tanks bleeds air from 4 corners of the cylinder head and gets suction from the water pump for circulation.

The header collectors are semi merged with  welded interior cone.  The headers dump into twin 3″ mid pipes.  Quick release V-Band clamps make exhaust removal super fast and easy, important in a competition car.  The transmission can be removed in just minutes with the help of this exhaust.

 The 3″ mid pipes merge into this 5″ oval section of the exhaust.  The exhaust is made entirely of 304 stainless steel.

 The old exhaust used to drag on the ground due to the car’s wheel lifting antics.  The new exhaust is 5″ oval to improve ground clearance.  The Muffler is a straight through perforated 5″ oval core Spintech.  Surprisingly the exhaust is quiet for a race car, much quieter than the old exhaust.

 The huge 5″ oval tip is no rice and all business!
