New Products for the 2015+ Subaru WRX
Radium Engineering has just released a range of products for the 2015+ Subaru WRX with the FA20 engine. These products are designed to improve the driveability and performance of the WRX without sacrificing reliability. 
The WRX version of the FA20 engine is equipped with tumble generator valves to assist with emissions during cold engine temperatures. These devices also impede air flow in the intake manifold runners. By eliminating the obstruction, a clear airflow path is established. The Radium Engineering TGV deletes are machined from 6061 aluminum and anodized green or black. Installation is quick and easy (compared to EJ-series engines) and can be performed in about 30 minutes.


The tumble generator valves are an emissions control device, and as such should be removed only for vehicle operating off-highway. It is also recommended that a complimentary engine management tune be implemented to take full advantage of the TGV deletes. No permanent modifications to the vehicle are necessary to install the TGV delete kit.

Even with low mileage modern cars, oil accumulation in the air intake stream can happen. The Subaru FA20 engine places the turbocharger down low, in front of the engine. This leads to oil from the PCV system collecting in the turbo air inlet pipe, down near the turbocharger. This oil is result of blow by coming through the crankcase ventilation system. This oil will eventually be digested by the turbocharger and deposited through the charge piping and can even result in blue smoke from the tailpipe. 

The Radium Engineering Dual Catch Can Kit intercepts the PCV gasses and traps the oil and other pollutants before they can make it back into the intake stream. The kit tucks in perfectly on the RH side of the engine bay next to the ABS module, mounts to existing engine bay fasteners and requiring no relocating of engine bay components. The front catch can intercepts the crank case vent hose that connects to the turbo inlet pipe, keeping oil out of the turbo inlet. The rear catch can intercepts the PCV hose coming off the block and going to the intake manifold, keeping oil out of the intake manifold. The catch cans are designed to withstand boost pressure and are sealed, so direct connection to the intake manifold, even with forced induction, is OK.
This kit is perfect for a street driven car experiencing mild amounts of blow-by.

For more race-centered applications, or cars with built high-powered engines, more oil blow by is usually experienced, often overwhelming the volume of the standard Radium catch cans.  For these applications Radium Engineering applied it's Air/Oil separator to the FA20 engine.

The Air/Oil Separator functions in a similar manner to the catch cans, however, the big difference is that oil is returned back to the engine, rather than stored in the catch can. But catch cans do not only catch oil, they also catch water condensation and it is not ideal to have this water mix with the oil, then return it to the engine. To remedy this, the Radium AOS is heated with engine coolant. This keeps the water vapor from condensing and mixing with the oil.

Engine coolant is plumbed through the bottom plate of the AOS.

Another important aspect of the AOS is that it does away with the function of the PCV valve. Instead, the engine is allowed to breathe freely from both the crank case vent port (at the front of the engine) and the PCV valve port (under intake manifold). The PCV valve is removed from the engine block and replaced with Radium's custom made PCV delete fitting, shown below.

This fitting screws into the block and adapts to a -10AN male. It is straight through, with no check valve or any other device built in. This allows maximum ventilation to the AOS through this port. This is also the path for collected oil to drain back to the engine block.
With both engine ports breathing freely into the AOS, the AOS needs to be vented to atmospheric pressure. This is done by routing the AOS side port back to the turbo inlet pipe. This creates a closed-loop system.
The AOS was designed to mount in the engine bay near the brake master cylinder (for LHD vehicles only) using the Radium Master Cylinder Brace for the 2015+ WRX as the mounting point.

The master cylinder brace is a simple and effective way to reduce firewall flex resulting from brake pedal pressure.It is machined from 6061 aluminum and mounts to the strut tower using pre-existing threaded holes. Clearly visible in the photo below are the three threaded holes in the brace where the AOS bracket attaches.  The brace is sold as an individual item, or as part of the AOS kit.

While installing an AOS kit can be done with the stock fuel feed hose, Radium offers an aftermarket fuel feed hose replacement that cleans up the fuel routing and offers better clearance with the AOS. The hose has a PTFE core that is compatible with all fuel types and also features machine-crimped end fittings.

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.

The Classic VW Bug

When it comes to performance, a 1930's economy vehicle labeled "The People's Car" doesn't come to mind. The aircooled VW Type-1 (Beetle) was commisioned by Adolf Hitler and designed by Ferdinand Porsche. But because this was the longest running, most manufactured, car worldwide, there are plenty of options for creating a custom tailored vehicle. Radium co-owner JP purchased a 1965 volkswagen in 2004 specifically for this purpose. His main goal was to create a unique Subaru powered VW bug that would be capable of doing wheelies on the street.

A couple quick purchases and here comes a brand new 2.5L Subaru STi block...

...and an oversized SuperTech valve job from Tom at Port Flow. JP fabricated a stainless steel muffled exhaust system.

Power was transmitted to the wheels using a Rancho prodrag transaxle with an aluminum spool and Sway-A-Way heavy duty swing axles.



In order to properly operate the twin disc clutch's heavy pressure plate, the VW cable actuation was swapped out in favor of a hydraulic master and slave cylinder.



The VW 4 wheel drum brakes were swapped out for disc brakes with 4 POT calipers from Wilwood (below). A Wilwood adjustable proportional valve was required as well as a line lock for drag racing burnouts, both shown above.



JP wired in the EFI system which uses a AEM Universal "Race Box" EMS mounted underneath the rear bench.



For 5 years the car was transformed and looked great, externally.



But in 2009, JP decided the Bug needed a full restoration as there were some necessary body repairs and quite a bit of rust underneath that needed attention. First thing was to separate the body from the pan.



Next, the old floor pans were cut out and new floor pans were welded in place, shown below. 

The entire chassis was then powdercoated gloss black (above). Also the adjustable beam, tie rods, control arms, etc. were powder coated (below). New QA1 double adjustable shocks were installed to help weight transfer for massive wheels stands



Once the widened Porsche Fuchs wheels were reinstalled, the vehicle was aligned.



After the body shell was painted Lotus Aspen White Pearl and reinstalled, the floor pans were insulated before the carpet was installed.

Four jack points are fabricated from aluminum and anodized Radium green.



The headliner and all of the glass was reinstalled and a roll cage was built to comply with racing standards.

Lightweight power windows were installed in order to avoid window crank interference with the roll cage.



The roll cage ties the chassis, body, and engine together for a solid mount.



A Porsche 993 Turbo OBC tachometer is used with a working coolant temperature and road speed digital display.



The factory 2 point harness was tossed for Sparco 4 point harnesses and a modular harness bar. To avoid snapping a neck with 1960's seats without head rests, retro (period correct) ProCar seats were installed.



Because the VW body is a natural air foil, JP designed a removeable wing to keep the car planted down the track and to aid in cooling the secondary radiator and intercooler.

The angle of attack on the wing is adjustable for optimal downforce.



The revised car kept its classic look with modern touches.

The front and rear fenders were slightly widened in order to fit race tires.

Radium Engineering oil catch cans take care of oil separation from the cam covers and crankcase.

The engine runs flex fuel (E85) and starvation is cured thanks to the Radium Engineering E85 Fuel Surge Tank. Radium Engineering fuel pressure gauges are used for monitoring pre and post surge tank fuel pressures.



The front weels are 15x7 with a -21 offset (shown). The rear wheels are 16x9.5 with Hoosier drag radials.



The classic Porsche headlights use modern HID H4 bulbs. The original turn signals on top of the fenders were deleted in favor of European bullet signals.



With the exception of the VW headlight bezels, the classic chrome was removed in favor of texture black powder coating.

The car will be strapped on the dyno and is projected to make over 500whp thanks to the Garrett GT3076R turbocharger.

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.
Kyle chose a Radium Engineering dual Bosch -044 fuel surge tank (shown below) to feed his fuel hungry rotary.
Kyle is also building a second car for the Formula Drift Asia series and once again chose Radium for the fuel delivery.

Radium Engineering's Ultimate Fuel Pump Test

As part of our Fuel Surge Tank (FST) line, Radium Engineering carries various fuel pumps from select manufactures that differ in flow rates. Third party independent flow testing data on these pumps can sometimes be found with research on the web.  However, the data can be inconsistent between sources, presented in a way that makes comparison difficult, or may not exist at all.  This makes it hard to compare pumps directly. To remedy the issue we decided to do our own in-house back to back comparison test of all six fuel pumps we currently offer with our FST product line. This information would equip us and our customers with the knowledge to correctly choose a specific Radium FST.

The test measured pressure, flow rate, voltage, current draw, and sound level. The sound was measured in decibels (dB) using the sound level meter below...

For some customers building street cars, fuel pump noise is an important aspect. This test would give a good comparison between all the pumps.

Shown below are the six fuel pumps that were tested. All units were brand new off the shelf.

Top Row: Bosch 0 580 254 044 (External Pump), Bosch 0 580 254 040 (Internal Pump)
Bottom Row: Walbro F90000267 E85, Walbro 400 Gas, Walbro GSS342 255lph, Aeromotive 11142 340R

The flow test used a simple controlled orifice. The fuel pump line was restricted by the orifice until the desired line pressure was achieved and then flow was tested using a timed interval. The volume of fluid the pump output during the timed interval was measured to provide the volume per unit time (flow rate) at each line pressure.  As always, Mineral Spirits (specific gravity of .76) was used for the testing fluid. We are aware that there are more accurate (and expensive) ways to flow test fuel pumps, but this setup was adequate for us to compare the fuel pumps in identical test conditions. Also, note that these results should not be compared to other tests, since our test setup is inherently unique. So lets get to the results.


Flow Rate


Note: To convert to PSI, just multiply the Bar pressure by 14.5

The above chart shows the new Walbro 400 and Walbro F90000267 E85 have superior flow when compared to the others, even the "mighty" Bosch 0 580 254 044. One interesting note is that unlike the other pumps, the two Bosch pumps maintain flow level extremely well as pressure increases.



We generated this table as a rough guide to use when estimating the Horsepower supporting capacity of the fuel pumps. This guide is approximate and there should always be a built-in safety factor when selecting the pump.


Current Draw




Looking at electrical current, one can almost make the assumption that the more current the pump draws, the more it flows. The high flowing Walbro 400 pumps draw close to 20Amps at 6 bar! There are a couple exceptions to this though. For instance, the Aeromotive pump required more current than the Bosch 0 580 254 044, but flowed less than it.

The sound level was measured inside the main 5 gallon fuel container. All pumps were fully submerged in the testing fluid. The sound level (shown below) was the average of two readings taken at low and high pressure. Sound is highly sensitive variable and can be influenced greatly by the surroundings, this required extra effort on our part to maintain precise consistency during each sound measurement.



The Walbro GSS342 255lph takes the prize as the loudest pump followed by the Bosch 0 580 254 044. It is interesting to note that the highest flowing pump in the group (Walbro F90000267 E85) was also the quietest.
Keep in mind that many factors effect real world pump noise levels in the vehicle and are not reflected in this test. Also, while the Walbro GSS342 255lph was the loudest in this test batch of pumps, there are many aftermarket branded fuel pumps not included in this test that are considerably louder and do not flow much more, if at all.

So now lets talk value. A certain fuel pump may flow well, but if it costs 5 times more than one that comes close, what is the point? Below is a chart that shows flow per dollar. Note: We used retail prices for all pumps.



The chart shows that the Walbro GSS342 255lph gives the most flow per dollar spent. In fact, all the Walbro pumps show to be good value. Due to their high price, the two Bosch fuel pumps are not as good a value.


Conclusions


Walbro GSS342 255lph:

Excellent value and proven reliability in a small package. While the loudest of the batch, it is still an OEM quality pump so it is all relative. These pumps are used extensively all over the world and are "hands-down" the most popular in the aftermarket world.
Single Walbro GSS342 255lph FST
Dual Walbro GSS342 255lph FST

Bosch 0 580 254 040:
A low current drawing OEM Audi pump with a Bosch badge that offers consistent flow across a wide pressure range. Note: The low current draw will help keep fuel temperatures down. 

Bosch 0 580 254 044:
This age-old design used on classic Porsche and Ferrari still holds its ground quite well, but its high price and high noise level keeps it from being the best.
Dual Bosch 0 580 254 044-Horizontal FST
Dual Bosch 0 580 254 044-Vertical FST

Aeromotive 11142 340R:
This compact high-current drawing pump heated up our test fluid quite quickly, but also performed quite well and has a reasonable flow per dollar value.
Single Aeromotive 11142 340R FST
Dual Aeromotive 11142 340R FST

Walbro F90000262 Gas and F90000267 E85:

These new pumps from Walbro perform extremely well on all fronts; flow, noise level, and value. They set a new bar for flow from a compact package. Just make sure your wiring can handle 20A of current!
Walbro F90000262 Gas and F90000267 E85 FST




We hope this information will assist our customers when considering what pump to use with their surge tank.
