What a Crankshaft Scraper does: Crankshaft scrapers have been used for many years and can be found in every form of racing. They reduce the "oil cloud" that the rotating crankshaft creates in the bottom of the motor by "scraping" off the counter-weights as they come around. This reduces the amount of air whipped into the oil by the crankshaft, lowers the oil temperature, and saves HP. When it only takes 30% entrained air bubbles in the oil to damage a connecting rod bearing, the simple installation of a good set of crankshaft scrapers can lengthen engine life significantly.
What a Windage Tray does: Windage trays help keep the oil down in the bottom of your oil pan, or "sump" where it can be picked up by the oil pump and recirculated. High braking loads, high acceleration speeds, and high cornering loads all want to make the oil climb out of the sump and away from the pickup tube. When this happens, the oil pump pickup tube can become uncovered and the oil pump will suck air instead of oil. Oil pressure will drop off, and engine damage will soon begin. A good windage tray keeps this from happening.
Description: Our windage tray and scraper system has been a collaborative effort between us and the Manufacturer for 3 race seasons. You benefit from our extensive in-car and real-world trial-and-error process under the most grueling of engine conditions.
The scrapers and tray are plasma-cut from steel, and, where needed, special one-way oil screens are tack welded on to them to let oil flow in one direction, but not the other.
Comprehensive installation instructions are included. Some mechanical skill to install is required. Best when installed during an engine build, but they can be installed with the engine in the car.
Benefits:
- Cooler oil temperatures
- Longer bearing life
- More stable oil pressure
- A reduction in crankcase vent fluids
- Oil catch cans will take much longer to fill
