Accusump System

ScienceofSpeed Accusump Oil Accumulator System

Severe engine damage due to oil starvation at the track during high G cornering is the number one cause for engine repair at our shop. This oil accumulator system reduces the chance of oil starvation to engine bearings by keeping a store of pressurized oil that can be injected into the engine in the case that the oil pick up runs dry. This pressurized oil then refills into the chamber once the NSX regains normal oil pressure.

In addition to adding a safety margin against oil starvation, the system also provides pre-oiling during start up to prevent metal-on-metal contact during start up of the engine.

This is a standard method used to safe-guard against engine damage in nearly every race car built with out a dry sump oil system. ScienceofSpeed has designed a system to offer a drop-in solution for cars used both on the street and track.

Our system includes the oil accumulator, all plumbing, and electrical components required for a direct drop-in solution.

The system utilizes an effective electronic valve and sensor design. When the car is first powered on, the sensor detects the lack of oil pressure, and opens the valve to pre-oil the engine before the starter motor fires the engine allowing the engine to produce oil pressure on it's own. Once the engine is up to regular oil pressure, the valve is then allowed to replenish the canister with oil. Then, at any time where the engine experiences oil starvation, the sensor will then cause the valve to open, and release pressurized oil into the engine. Once the oil pressure again returns to normal running condition, the oil canister again refills itself. During racing and hard driving conditions, this cycle will continue automatically discharging and refilling as you corner, accelerate, and brake.

normal running condition:
oil pick up supplies oil from oil pan via oil pump and supplies oil to engine

low pressure condition:
oil pick up runs dry during high G force condition, accumulator injects oil into engine

The system injects oil into the car at a unique point for the NSX using the factory's oil adaptor banjo bolt. Using a specialized banjo bolt with injection ports machined into the bolt with a AN-10 male fitting, we can inject oil at the most critical point of the engine as oil leads into the crankshaft for system lubrication.

Specially designed banjo bolt replaces factory banjo bolt to inject oil directly into the engine with out modification to the existing oil system

The kit is plug-and-play designed specifically for the NSX. The oil canister can be placed in the rear right fender well or attached to the inner trunk firewall. Everything required for installation is included. Some parts not shown in above photo. We also highly recommend our oil pan baffle to be used in conjunction with this system to prevent engine damage.

This system can also be used in conjunction with an oil cooler including the ScienceofSpeed Oil Cooler System for NSX.

Two capacities available:

2 quart model - canister is 12" x 4.25" - offers oil surge protection - more compact size allows more flexible installation.
3 quart model - canister is 16" x 4.25" - larger capacity designed for high endurance track heavy applications where prolonged high G corners will be experienced. 3 quart requires additional fittings (included) and includes custom mounting brackets to accommodate the longer canister. ScienceofSpeed recommends the larger 3 quart system for cars used with R compound tires and/or on tracks with high lateral G loading.

Please note: The oil banjo bolt is offered on exchange. A $20.00 core charge will be added to your order on check out. This is refundable as long as the core oil banjo bolt is returned within 30 days of receipt of the product.

Important Ordering Note: The ScienceofSpeed Accusump Oil Accumulator System is sold as a stand alone kit or may be installed with the ScienceofSpeed Oil Cooler System. If used together, the components used differ. If the oil cooler will be installed at the same time as the Accusump, please order either enpp-963 or enpp-964 rather than the two separately.
