New applications for plumbing your own racecar for dry sump oiling systems and new race gas chemistry are constantly being created. The need for new hose and hose pipe ends that can handle these liquids are also in growing demand. The particular technology that offers these benefits trust polytetrafluoroethylene (P. T. F. Electronic. ) or “Teflon” hose lining technology.
Impervious to all racing liquids that can eventually break down rubber plus synthetic rubber hoses, this Teflon-lined design is also ideal for use with dried out sump engine plumbing and as well as other high vacuum applications.
The P. T. Farreneheit. E. plumbing is less of the exotic and more of a new regular, which has intensified the challenge to improve a few of the shortfalls offered by “the first generation” P. T. F. E. line.
We talked along with Brint McLellan with Fragola Performance Systems about its relatively brand new Race-Rite and Race-Rite PRO ranges of P. T. F. Electronic. hose and hose ends. Probably the most notable features crucial to racers may be the new uniformity of the hoses’ within diameter.
The Fragola Series 6000 P. T. Farrenheit. E. hose is a proven artist through recent years. Its solid coating and braided sheath is long lasting, but restrictive when it comes to its twisting capability. The new Race-Rite hose also offers the smooth P. T. Farrenheit. E. lining, but with a convoluted core design accompanied by a wound spin out of control wire. This new design can be capable of a tighter bend radius and higher flow rates.
Improvements Using the Inside Diameter
McLellan explains, “If we go through the older generation 6000 Series P. Capital t. F. E. hose, the inside size is only 1/2-inch for a -10 A GOOD hose and fittings. The standard to get a -10 AN system should be just about all 5/8-inch. With the new Race-Rite ranges, you get the properly specified within diameters that racers are used to, along with standardized braided steel plus nylon braided hoses. ”
One of the biggest variations is that the new Race-Rite hose operates true to size. So , for example , the -6 Race-Rite hose has a true-standardized AN measurement of the inside size of 3/8-inch, unlike the old P. T. F. E. line designs that have a smaller inside size. – Brint McLellan, Fragola
Bending radius Improvements
Even though already a well-made and well-known product offered to this day, one enhancement we see when comparing the Fragola Series 6000 to the Race-Rite hose pipe is the improved bending radius. Whenever we plumbed our Project Rover Chevy Camaro bracket car for E-85 fuel use in a previous article in Dragzine , we were limited to a four 1/2- to 5-inch bending radius, as we used -10 AN hose pipe and fittings on the Camaro’s recirculating fuel system.
“With the Series 6000 hose, the particular smooth-bore inner liner is fuller and restrictive for some tight bends, ” McLellan exemplifies. “One from the key updates with the Race-Rite tubes is still a smooth, but thinner L. T. F. E. liner which is housed by a convoluted core. The particular Race-Rite PRO hose has a metal wire wrapped between the layers. These types of hose designs prevent kinking; you are able to really tighten-up your bending radius a little bit. ”
Another benefit related to the brand new Race-Rite and Race-Rite PRO line design is the ability to survive 28-inches of vacuum. Dry sump plus fuel system plumbing can fall lines in extreme situations exactly where they can suck shut on the inlet side of high volume fuel plus oil pumps.
Crimped vs . Reusable Hose pipe Ends
Each styles of hose ends are available for the particular Race-Rite hoses. Many racers have got mastered the increased complexity associated with installing the “olive” design; recylable hose ends inserted onto L. T. F. E. lined hose pipe. Still, the popularity of the crimped hose pipe ends is gaining in recognition, as well.
You may be capable to find a local Fragola Performance Techniques dealer who has outfitted their store with the hydraulic crimping system. Irrespective, McLellan comments that many racers the actual measurement instructions within their catalog plus order custom factory crimped tubes without problems.
It impresses many that the crimped and recylable hose end options are very equivalent in price. With that, enthusiasts are getting much more comfortable with the process to carefully calculate and order the very durable crimped ends. Fragola sees an increased variety of orders for crimped AN fixtures for P. T. F. Electronic. hoses.
“Many guys will remove their previous plumbing system from their vehicle plus send it to us, ” McLellan explains. “Then, we simply duplicate each hose in the Race-Rite series…as easy as that. ”
The crimped fixtures also offer the benefit of a more compact appropriate compared to the reusable fittings. “It might not be a huge issue in many applications, ” says McLellan, “but it is a benefactor in dry sump oil techniques and some tight spots in gasoline plumbing. ”
Weight And Heat Benefits
McLellan says that lots of racers have reported 40- in order to 60-pounds of overall weight financial savings when re-plumbing an entire car.
“A system consisting of give food to and return fuel system, a few oil lines, and possibly some nitrous oxide or turbo inner coil outlines can see those savings, ” he admits that. “With a dry-sump oiling program added, you will see even more weight eliminated. ”
Another detailed feature of both hose ranges is the temperature durability. Specified having an operating range of -65 to +500-degrees Fahrenheit, it may be overkill for many apps in the automotive market, as McLellan states.
“But with regards to the drag racing automatic transmitting related to external cooling systems and exterior dump valves in use, it is helpful, ” McLellan says. “Many possess jumped onto the product usage for all those applications. ”
Fuel Durability
The Teflon-lined plumbing was made famous with the advent of ethanol-based fuels within racing. More and more often, many teams make the P. T. F. Electronic. -lined hose upgrade for a number of performance fuels.
McLellan explains that standard synthetic rubberized hose can last from up to seven-years to as little as two to three seasons depending on usage with various gas, methanol, oxygenated, and maybe some exotic diesel powered fuels. Combined with expensive fuel penis pumps and fragile electronic fuel injections, racers could instead make the in order to P. T. F. E. rather than get a surprise.
The particular reusable hose ends fittings with regard to P. T. F. E. -lined hose use an “olive” assembly style. With these fittings, this assembly procedure is more complicated, but can be perfected like any standard hose and A GOOD fitting.
“The VP Racing Fuels M1 continues to be cited in recent times for really wearing down fuel lines at a rapid price, ” discloses McLellan. “We resolve lots of racer problems regarding gasoline line breakdown by utilizing P. To. F. E. – lined gasoline systems. ”
Fire Resistant Exterior
Another feature within the spec-sheet for the new generation P. Big t. F. E. hoses is the dark aramid braided cover. McLellan describes, “Aramid is defined as “a lightweight yet very strong heat-resistant synthetic aromatic polyamide. This outer weave on the Race-Rite hoses acts as a firebraid material. ”
Long List associated with Benefits For Motorsports
This newest generation associated with plumbing can flawlessly take on any kind of fluid transfer while also attaining the benefits of better bending characteristics as well as a heat-resistant braid cover.
A combination of early and new G. T. F. E. hoses could be the ticket with a fresh racecar set up. The durable braided steel sheath in the 6000 Series hose might be restrictive in bending, but functions fine in under-car fuel plumbin, such as in our project Camaro. The newest Race-Rite hoses offer far excellent bending capabilities shown here, plus come with an “aramid, ” or high-temp braided cover.
The increased inner diameter from the hoses that now match appropriate -AN fitting specifications also advantage critical flow rates while accumulated to considerable weight savings more than your overall plumbed systems.
It is a no-brainer that P. To. F. E. -lined hoses plus related hose ends are not going anywhere soon as a viable application. Racing energy sources will continue to change in chemical substance makeup; and more extreme pressures plus temperatures will need this next-generation domestic plumbing to keep the fluid flowing with out breaking down your hoses.
