New Product: Adjustable Fuel Pressure Regulator

Radium Engineering is proud to announce an all new universal adjustable fuel pressure regulator (AFPR) for high performance vehicles.


The AFPR is CNC machined aluminum which is anodized black and laser engraved. Instead of tapered pipe threads, the unit design includes 5 ports that are O-ring sealed.

So why another regulator?  With all of the universal FPRs on the market, we could not find one that installed seamlessly into multiple pump fuel systems. To solve the problem, installers were left with a choice of using Y-blocks and other awkward T-fittings for proper plumbing. So we decided to create a solution with a new high flow regulator, keeping in mind the needs of our fuel surge tank customers. Lets take a closer look at the AFPR and see why it is the best choice for difficult fuel plumbing situations.



The arrangement of the AFPR ports are different than any other regulator. Every FPR on the market directs the return port downwards out the bottom of the unit. This makes it limited to wall mounting and difficult to nearly impossible to mount the FPR to a floor. Furthermore, the return port requires a 90 degree elbow which are expensive and not always available with a swivel option. We took this port and converted it into a "return chamber" (bottom port shown above) that runs in-line with the high pressure ports. The chamber is threaded at each end for 9/16"-18 (-6AN). This allows the regulator to be easily floor mounted, such as in a trunk near a surge tank, without any 90 degree hose-end fittings. The installer can choose to connect the return line to either end of the return chamber making the AFPR suitable for their installation. Unless there is a need to use two -6AN return hoses, the opposite end is blocked off using the included plug(s).



Here is a cut-away (fittings installed in all ports) showing the return chamber. Bypassed fuel comes down the center of the body into the fuel return chamber then exits through the return port(s).


The high pressure ports on the AFPR are also unique. Most regulators have single ports on opposing sides. This is not always helpful when working with multiple fuel pump lines. The Radium AFPR is configured with 3 high pressure ports; two 9/16"-18 (-6AN) and one 3/4"-16 (-8AN). Shown in the picture above is the -8AN (top port).


On the opposite side, there are two -6AN pressure ports (shown above). This design makes plumbing two fuel pumps easy and eliminates the need for an expensive Y-block fitting. Each pump can feed into one of the -6AN pressure ports. The -8AN port on the opposing side is then used to route fuel to the rail(s). This is an excellent way to construct a robust dead-end fuel system which is ideal to keep fuel temperatures low. The AFPR can also be easily used as a traditional return-style regulator. Please visit the product page to find additional information on plumbing the AFPR.

On most other aftermarket FPRs, there is a 1/8" NPT port on the front of the unit. When not using this for a transducer, gauge, sensor, etc. it has to be plugged with pipe tape or paste. Often times there is no room for these ancillary components as the entire unit as a whole becomes too big and causes interference with nearby objects, such as an intake manifold. Furthermore, in cases such as a returnless system, the pressure reading should be taken at the fuel rail for accuracy. The AFPR does away with an integrated pipe fitting. Instead, if the -8AN port is not used and the AFPR is mounted near the fuel rail, Radium offers a special billet 1/8" NPT adapter fitting (shown in green) to connect gauges, sensors, transducers, etc.

Furthermore, when this port is used, the component sits inline with the hoses making it less prone to object interference.


The AFPR also features a unique interchangeable return port that accepts 3 different ID orifices. This allows 1 regulator to work with a wide range of fuel systems. The AFPR has been tested using ranges from low flow OEM pumps to multiple fuel pumps delivering over 1400LPH of fuel flow. This means the AFPR can be used in virtually any fuel injection application. All that is required is a simple swap of the included orifices (0.10in, 0.18in, 0.25in).

Shown in the graph above is the minimum fuel pressure the regulator can provide as a function of pump flow rate.


For fine-tuning fuel pressure, a stainless steel set screw and jam nut is used. The OEM quality diaphragm changes fuel pressure at a 1:1 ratio when the 5mm barb is connected to a vacuum source.


The included powder coated bracket can be used to mount the AFPR to a floor or other flat surface. For wall mounting, simply secure the AFPR using the 2 through-holes in the regulator body and long M6 stainless steel bolts (the bracket is not required). Also, when wall mounting the AFPR, it can be flipped 180 degrees to suit the direction of which side the -8AN and two -6AN ports are pointed.

Like all Radium Engineering products, the AFPR is made in the USA and carries a lifetime warranty. For more information, please visit the AFPR product page in the Radium online store.

Radium Engineering and the PSI Cruise-in 2013

Mid-July means its time for the annual cruise-in at Portland Speed Industries in Hillsboro Oregon. Once a year PSI opens their door to the public for a chance to see the facility and talk with the staff and visit with friends.


The cruise-in was the perfect opportunity to take JP's recently reassembled VW Beetle for its maiden voyage.


JP said since owning the Bug in 2004, this 45 minutes was the longest drive of its life with the STi engine in tact. A full detailed feature on this car will be coming to our blog soon.


As always, the quality of the vehicles partaking is always worth it.


Scott Peterson is a local machinist we use to machine Radium parts. He was out with this remarkable pro-touring G90 Camaro.


Scott has been doing extremely well showing the car and has taken home many trophies from some major car shows. If you want to learn more about this car, CLICK HERE for a link to Scott's build thread.


Evergreen Pro-Am drifter Cameron Moore also came by to show off his Radium emblazoned SC300 drift car.


Cameron loves all his Radium parts including this trunk mounted twin-Bosch 044 Fuel Surge Tank system.

Who's Drifting with Radium in 2013?

The 2013 season of Formula Drift is turning out to be just as exciting and suprising as last year.  As we approach the last two events on the schedule, we thought we would take a look at the teams who have partnered with Radium Engineering to stay competitive this season. Teams come to Radium when they are looking for the highest quality no-nonsense components for their race vehicles. A failed component at a competition can mean the difference between a win and a loss, and ultimately may affect the running for the season champoinship. Radium Engineering is proud to partner with these teams and drivers to help them reach their goals.

Here is a summary of who's running what in the Formula-D pro drift circuit from Radium Engineering: (in no particular order)

KYLE MOHAN

Kyle is a Pro-Drift veteran and a rotary specialist.  He is one of the only pro competitors running a turbocharged rotary engine in his Mazda RX-8. Kyle is not only the driver, he is also an expert mechanic and builds his own cars and engines. Kyle is the head technician at Mazdatrix, a rotary performance shop in Southern California. We first partnered with Kyle in 2012 and look forward to supporting him throughout the season and year to come.

New Product Release: FST-R....Two parts in one!

Radium is proud to release the first ever fuel pressure regulated surge tank. The innovative FST-R (Fuel Surge Tank - Regulated) is a fuel surge tank that houses a single internal fuel pump and has a fuel pressure regulator integrated in the top cap. This revolutionary idea eliminates the need for an external regulator along with the extra hoses and fittings associated with it.

This setup offers multiple benefits:
1. Reduced overall system cost
2. Reduced fittings resulting in less potential leak/failure points
3. Reduced hoses resulting in a lighter FST system
4. Reduced fuel temperature from the elimination of fuel returning from the engine bay
4. Quicker, easier, and cleaner installation


The FST-R is machined from 6061 Aluminum and like all Radium Engineering products, it is fully anodized and compatible with all fuel types.

The integrated fuel pressure regulator has all the features of a market-leading regulator. The output pressure is adjustable using the screw on the top cap. It is also capable of 1:1 vacuum reference by securing a vacuum hose to the nipple on the top.


The clean and compact package does not add significant size to the Radium fuel surge tank. The regulated output port is located on the side of the cap.


Shown above with an AEM 50-1200 E85 compatible fuel pump.

Inside the surge tank, many of the popular fuel pumps we currently supply can be used including: AEM, Walbro, Deatschwerks, and Aeromotive. At this time, the FST-R can only hold a single fuel pump. If a dual pump surge tank is needed, please see our other surge tank offerings:
http://www.radiumauto.com/Fuel-Surge-Tanks-C54.aspx


The regulator features interchangeable orifice sizes to match the output of different pumps.

When purchased with a pump, the FST-R will come fully assembled and pressure tested. Radium assembles the FST-R with the properly sized orifice for the pump. Two extra orifices are provided should the user ever decide to change pump.


A fuel pressure gauge/sensor should be installed on the high pressure output line (or fuel rail) to adjust the regulator. The Radium Fuel Pressure Gauge is perfect for this duty.

This FST-R works by converting to a returnless dead-end system. Unlike a "returning" fuel system, fuel sent to the fuel rail(s) is not returned back to the fuel tank. See the diagram below which shows the difference between a returning and a dead-end system.

One of the benefits of a dead-end system is that fuel heated by the engine is not circulated back to the surge tank or main fuel tank. This keeps heat out of the fuel system. Most modern vehciles use a dead-end fuel system for this reason and for improved EVAP emissions.

Is fuel flow restricted or fuel delivery "uneven" in a dead-end system? See the picture below of Dean Kearney's Formula Drift Viper which utilizes a dead-end system. Notice the FPR mounted in the image. This car runs a single -8AN hose up to feed the 1,000+Hp engine.


Radium also has extensive experience with E46 BMW fuel systems for S54 (inline-6) engines making over 1,000whp. BMW is one of many manufacturers that use dead-end fuel systems.  Radium also successfully runs a dead-end system on their turbocharged Lotus Elise.
