Doorslammer Tech…what’s hot !!!
This filter assembly is designed for racing, the filter element can be visually checked in just a few seconds. This makes it possible for a circle track racer to check the filter element for excessively wearing engine parts, even during a pit stop in the middle of a race. Now drag racers can easily check the filter element between rounds. The old style filters made this almost impossible, especially in the later rounds. There is not enough time to take the old style oil filter apart, and clean up the mess, and put the filter back together. The racer usually has to take the filter apart when it is very hot. No madder what kind of racing you are doing, Clear View Filtration’s new Oil Filter Assembly will give the user the ability to keep track of their engine, by being able to visually check the filter in seconds without draining or leaking any oil, unbolting or loosening any fasteners or fittings and you don’t loose any fluid out of the fluid system.
The Filter Assembly is machined out of 6061 T6 billet aluminum and Clear Anodized for Protection and Durability. The Sight Window is made out of high-grade plastic that is chemical, heat, scratch, and shatter resistant. The Filter Element is made out of stainless steel mesh that can easily be cleaned and reused.
Twelve Radial Groove Openings operate like twelve individual filters enclosed into one Filter Assembly. This allows more fluid to pass through the Filter Assembly without restriction, even as the Filter Element is plugging up with dirt and contaminates. If one of the twelve grooves were to plug completely the fluid would flow through another groove that was not plugged completely.
The Filter Assembly also is equipped with a Pressure Relief Valve. If the filter pressure rises due to the Filter Element plugging up, the Relief Valve will open allowing fluid to pump through the Filter Assembly even if the Filter Element were to plug up completely. This will help prevent motor failure caused by the filter being plugged.
The filter assembly part #100 is designed for fluid systems with a max working pressure of 125 PSI at 180 degrees temperature. If filtering higher pressures or temperatures, contact us and let us know your application. We can also design and supply Clear View Filtration’s filters assemblies for custom applications.
The physical dimentions of the filter assembly are: 6 3/4″ Wide x
7 3/4″ Long x 3 1/4″ Thick and Weight’s 5 1/2 pounds.
Davis Technologies Can Hook You Up!
By Ian Tocher (Contributing Editor- CompetitionPlus.com)
What do top-level drivers like Tim Lynch, Mo Hall, John Stanley, Joshua Hernandez and Gaylen Smith have in common? They all rely on Shannon Davis for help in hooking up at the track.
No, Davis isn’t going to find a date for them on Saturday night, but the former IMSA sports car crewman has developed a unique electronic traction control (ETC) system that just might help them reach the winner’s circle come Sunday.
All Davis Technologies ETC units use eight, precision-machined sensors attached to the driveshaft to determine within an eighth of a revolution if that fraction of rotation occurred too quickly based on the average of what the driveshaft turned over several previous revolutions. The deviation typically is corrected by briefly retarding the engine’s timing, but also could involve reducing nitrous injection or lowering boost.
“We’re measuring in what’s called microseconds, which is millionths of a second, so it’s very, very fast to react, much faster than other systems that have just two or four magnets to trigger sensors,” Davis says.
Davis offers two basic types of ETC: non-self-learning and self-learning, and two levels of self-learning units, with the only difference between the two being their extent of tunability.
“The non-self-learning is basically our Sportsman box and what it’s doing is just watching for a random acceleration that exceeds a certain value. The self-learning unit monitors the rate of change and if it detects a sudden deviation within that rate of change it makes a correction. The advantage is that you don’t need to predict the future with it; you don’t need a crystal ball like you do with your dots and some of the other systems out there,” Davis says.
“Some people seem to think the Sportsman box isn’t as good because it’s cheaper, but they both work on the same basic principle; it’s just not the self-learning type,” he stresses. “For the drag radial guy who might be having trouble on the gear changes, it works great and it’s all someone like that probably needs. Once those cars are rolling and up to speed they’re not nearly as likely to break a tire loose again as the high-powered Outlaw 10.5 or Pro Mod guys are.”
The Sportsman box works off what Davis calls “an adjustable fixed-rate,” which means the user sets the maximum rate at which they want the driveshaft to accelerate. Basically, the user dials in a preset deviation based on RPM rate of change to trigger the ETC whenever the driveshaft exceeds that rate-of-change preset. It’s a one-time setting that unlike some other devices does not require plotting or mapping a series of preset RPM limits.
This method very effectively corrects early tire spin and helps with gear shifts, but Davis admits it’s not so effective at picking up subtle tire spin that doesn’t reach the deviation threshold at high speeds. He cautions, however, that simply lowering the rate-of-change threshold is not a desirable alternative.
“What that would do is make the system come on all the time when you’re launching, even when it’s not spinning but just accelerating hard in first and second gear, so you’d be retarding the engine constantly and killing your power,” he explains. “For guys that need to control that slippage anywhere on the track, they can move up to one of our Drag Lite or Drag Pro units, which in addition to employing the self-learning technology also include much more tunability.”
Regardless of the type chosen, it’s an easy install, one that usually requires only a few minutes to complete.
“Typically, we replace the ring you already have that triggers your data system or engine control unit with our ring and sensor and our sensor has multiple outputs, one for us and one for your Racepak or FAST or Big Stuff or whatever control unit your using,” Davis says.
Davis also emphasizes if a racer purchases a Davis Technologies Drag Sportsman box ($1995), the option usually exists to upgrade to intermediate Drag Lite ($2995) or even Drag Pro units ($4495) by paying only the price difference. And for the remainder of 2010, including at the PRI trade show Dec. 9-11, in Orlando, Davis is offering a 10-percent discount on all new purchases and upgrades.
“I can’t say this enough; they all work on the same principle, the only difference is in the options,” Davis states. “I liken it to buying a C-class versus an S-class Mercedes. Yes, the S-class has forward-looking infrared, active body control, back-up cameras, massaging seats, you know, all the bells and whistles that some people may need or want. But the C-class is a pretty nice car, too; nobody’s going to complain about you bringing one of them home either. That’s like our Sportsman unit; it’s a real nice piece, better than anything else on the market, I’m confident of that.”
