| Hmmm, no Toyota engine here. The engine is based on a Chevy LS-6 engine. The Chevy is no crude redneck motor; rather, an all aluminum block built by Hasselgen sleeved for a bigger bore and destroked for good revving capability. The engine was originaly developed for Daytona Prototypes. The engine is slightly over 400 cubic inches and put out around 780 hp with a powerband spanning from 4000-8500 rpm. The engine is dry sumped for reliability under severe G loads and features a Kinsler ITB carbon manifold with individual throttle bodies for sharp throttle response. The management chores are handled by Motec. The Chevy engine is actually lighter than the Toyota V8 and was used as a time saver. Chevy small blocks are probably the most developed engines in the world and this fine example can be obtained almost off the shelf. A Toyota engine would require a lengthy development program complicating and lengthening the development of the car. The engine is set back all the way to the firewall. In compliance with Formula D rules, the stock firewall is unaltered |

| The ITB’s have such sharp throttle response that a heavily progressive linkage is needed to make the car more driveable |
 |
| The dry sump system’s external belt driven pump has two scavenge and one pressure stage. It evacuates the oil to the huge Peterson tank where it is de-aerated, pumped through an external filter and dual coolers before being pumped back through the engine. The dry sump is really important to insure the reliability of the big Chevy. It has not needed servicing in over a season and use in two different cars. The AN plumbing and hoses are all Earl’s superlite. Conventional oil systems can easily have up to 60% entrapped air when operating under competition conditions. Lubrication performance starts to drop greatly when the air content gets above 25%. Dry sumps are very effective at eliminating this entrapped air and as such, significantly improve durability. |
 |
| This high mounted swirl pot helps give the engine and rear mounted radiator a good solid point to bleed and purge air from the cooling system. All drift and road racing cars can improve cooling system performance with a bubble free system such as this. Aluminum hard lines feed coolant to the super trick rear mounted radiator. |
 |
| A cool feature of Peterson dry sump tanks is that they can be disassembled for cleaning in case of engine failure. This is an extremely important feature as debris are a leading cause of engine failures in new engines installed right after a failure. |
 |
| The dual Setrab oil coolers have their own fan since drift cars spend a lot of time idling in line waiting to run with no airflow through the heat exchangers. |
