Rep Power: 746

I found an interesting site dedicated to oil delvery, filteration, and cooling.
The site includes oil coolers, accusumps, remote filter with higher micron rating with minimal pressure fluctuations, Turbo after oilcoolers, Sandwhich plates, screen filtered an fittings, fuel filters, oil cooler thermostats, catch tanks, expansion tanks, power steering tanks, custom oil pans, drag oil pans, circle track pans, windage trays.

This is a really good read with good information. Check out for further example of the remote cartridge style filter. Flow rate is very high with no bypass valve with a good micron rating.

Pre Oiling
Independent studies have indicated that up to 50% of wear on engine components occurs during the engine start-up, before oil pressure can be established by the oil pump.
The Accusump can eliminate this "Cold start scuffing" by delivering oil under pressure before the engine is started.


What is an Accusump?
The Accusump, the original automotive oil accumulator, is designed to provide the engine with oil pressure before the starter is even engaged.
An Accusump is a cylinder shaped aluminum storage container that acts as a reservoir of pressurized oil, to be released when there is a drop in the oil pressure.
The Accusump is connected to the pressure side of an engine's oiling system and is charged by the engines own oil pump.
Its simple, efficient design revolves around a hydraulic piston separating an air pre-charge side and the oil reservoir side.
On the oil side of the Accusump it has an outlet that goes into the engine's oiling system, controlled by a valve.
On the air side it's equipped with a pressure gauge and a Schrader air pre-load valve.

How does an accusump work?
On initial start-up when the valve on the oil side is opened the pressurized oil is released into the engine and therefore pre-lubricating the engine prior to start-up.
The Accusump holds whatever oil pressure the engine has at the time that it is shut off.
After the engine is started and the oil pump has taken over, oil is pumped back into the Accusump.
This moves the piston back and pressurizes the Accusump until it equalizes with engine's oil pressure.
While driving, if the engine's oil pressure is interrupted for any reason, the Accusump releases its oil reserve again, keeping the engine lubricated until the engine's oil pressure comes back to normal.
This release of oil could last from 15 to 60 seconds, depending on the size and speed of the engine.
In racing or hard driving conditions, the Accusump will automatically fill and discharge when needed as you corner, accelerate and brake.

Surge Protection
The Accusump provides that extra margin of protection that you need against engine damage caused by loss of oil pressure.
Racing and high performance street engines by nature are put under a lot of stress by the high G-load situations they are commonly placed in.
As oil in your pan sloshes about, your oil pump pickup can become uncovered, which causes a loss of oil pressure and sets the stage for severe engine damage.
The Accusump provides oil during these times reducing the potential for damage.

Filter tech

here is a write up from jsa motors sourced from www.hybridgarage.com with a cartirdge style remotre filter and its benefits over stock or other setups.

CM filters were developed to better protect expensive racing engines. A filter was needed that would handle a continuous high flow of oil while filtering out small particles. The flow should not be restrictive even when the filter is partially contaminated and all the oil should be filtered all the time. The element should not be affected by moisture which erodes paper elements, and it should withstand pressure surges without collapsing or rupturing. The CM filter element meets these requirements and overcome the shortcomings of conventional filters. In the years since their development these elements have proven themselves in NASCAR, SCCA, IMCA, IRL, and NHRA racing and on countless street miles.
CM Filters, cut-away view Conventional spin on filters have an element made from porous material (usually paper) which catches contaminant’s on its surface. The flow limitations of this design require a compromise between large pores for more flow, which also lets bigger particles through all the time or a bypass which lets unfiltered oil during times of high flow. When designing the CM filter this compromise was eliminated by going to depth filtration, where oil flows through millions of intertwined passages and contaminant’s are caught within the element. The flow characteristics of this design allows for finer filtration with greater flow without the need for a bypass. The synthetic fiber element material which is moisture resistant is sandwiched between two steel cages for surge protection.

CM elements filter out particles down to 8 microns, half the size of what the average spin-on filter does and has a flow rate even when contaminated, that is far greater than that required by any automotive application. Depth filtration extends filter element life because it can catch far more contaminates without restricting flow. Because of it’s longevity CM filters are a natural match for use with the longer lasting synthetic oils.
CM offers several different types of housings for these elements. Lightweight aluminum remote canister housings are available for both the 2 5/8" tall and the 4 5/8" tall elements. While these styles have been most popular in racing, they are a good option for applications where a conventional spin-on is in a hard to access place. CM spin-on housings are offered for both the 2 5/8" tall and the 4 5/8" tall elements with thread and o-ring combinations that fits most engines. These machined aluminum housings will last the life of your car.

The technology in the automotive area has advanced greatly in the past years. Today’s engines develop more horsepower from smaller displacements, they rotate at higher R.P.M.s, with tighter tolerances, and generally run hotter. To maintain longevity under these conditions engines require a strong lubrication system. Today’s oils have also improved to meet these demands, by lasting longer, and lubricating better, but even the best oil can only provide protection if it is kept clean.
In an automotive engine, oil collects contaminates as it circulates through the engine, these particles should then be removed by the oil filter. Contaminant’s are present in all engines.They are a by-product of the combustion process which leaks past the piston rings. They are small particles of materials caused by the wearing of internal parts. Hot spots within an engine can cause oil decay (sludge) that needs to be removed. To be truly effective an oil filter needs to filter all the oil that goes through the lubrication system and remove these particles.
CM depth filtration removes more particles without restricting flow, providing the absolute protection needed.

Questions Most Asked
Q: Can you clean CM Synthetic Filter Elements?
A: No. CM Elements can not be cleaned because they work on depth filtration design where particles are caught within millions of tiny passages which run through out the element. This design allows for a much greater flow and the ability to hold far more particles than a conventional surface filter.
Q: When should I change my filter element?
A: Under normal operating conditions we recommend a CM filter element should be changed every 10,000 street miles. Many customers change the element every second oil change. Under circumstances when large quantities of particles are being caught, like in older engines, engines which have not had regular oil changes, new engines during break-in, or when some oil additives are used, the element may need to be changed sooner. When the normal operating oil pressure has decreased 4 lbs. to 5 lbs. the filter should be changed.
Q: How often do I change the O-ring seals?
A: Unless they are damaged they can last at least 4 filter changes.
Q: Do CM Spin-on Filters have an anti-drain back valve?
A: Yes. A flapper valve allows oil to easily enter the filter, while preventing it from draining out once the engine is shut off.
Q: Do CM filters have a built-in bypass?
A: No. The high flow of the CM element can handle more flow than that required by any automotive application, so all the oil can be filtered all the time.
