TracTuff Application Specific Dual Pass Radiator
In the past year and a half, I have done a lot of talking... about the radiators in these photos. The promotion and education has resulted in very positive responses on social media and sales have been great! The feedback has been even more awesome; I couldn't ask for it to be more positive. Unfortunately (and fortunately) a change had to be made. A falling out between a supplier and myself has led to a new relationship; one that I attempted to set up several years prior.
What has changed?
In short... EVERYTHING. The cores are now manufactured to spec by C&R and as a result of using such a substantially better core, the price had to be increased. I realize this may have put the product just outside of reach for many, but I'm trying to offer the best for the discriminating few.
Lets get into the details!
TracTuff application specific racing radiators are excellent general-purpose radiators, capable of cooling the most demanding of applications. The radiators are made to order, so you can choose from standard 1.25" hose, -16 male flare, or -16 Wiggins connections as well as a host of other options. Radiators are available in single pass, double pass, and triple pass with or without fan mounting provisions. The C&R core chosen as the "standard" for these listings, utilizes a 42mm rolled dimple tube which extends the full thickness of the core, unlike the multi-row cores. These all-aluminum radiators offer high-performance cooling and long-lasting durability.
- The cores tube holds more fluid than an equally sized 42mm core w/ multiple tubes.
- The continuous width of the 42mm tube allows the 7mm x 18 fins per inch (FPI) cooling fin pack to make more contact with the tubes.
- The increased fin contact increases efficiency by transferring heat from the fins to the passing air.
- The optimized
louver pattern and design of the C&R fins has been
proven in wind tunnel testing to outperform standard
automotive designs and incorporates a folded leading edge for increased durability.
As I ease into this new relationship, I will be slowly adding new dismissions. The first core coming in will produce the largest/ tightest fitting product for the EG chassis. The same core can be used for the EK and DC2 chassis, but it will not maximize the available vertical space (its approx. 2.00" short) on ASR radiator mounts. Actually fits perfect with OEM mounts.
NOTE: Single pass radiators place the inlet/ outlet on opposite sides. Dual pass radiators place the inlet/ outlet on the same side. Triple pass radiators place the inlet/ outlet on opposite sides. Radiator cap bungs can be added to either side; if you are not adding a radiator cap bung to the design... I can add a vent to get trapped air out. The drain can be placed on either side but I recommend choosing the opposite side from the outlet to reduce crowding. Accessory bungs are reserved for things like pressure, temperature, turbo feed, oil cooler feed or a fan switch. I don't particularly care for them... but I can add push through fan mounting pins or I can fabricate fan mounting tabs or a full fan shroud.
Applications that have front core support braces/ hood latch assemblies must be cut out in order to fully tuck the radiator under the upper core support. All radiators are meant to maximize the available space for the best combination of static air flow while the vehicle is in motion as well as highest flow possible when the fan is on. Some traction bars screw with the mounting... and I cannot accommodate for the various design differences without having your traction bar present. You can either ship the traction bar or I can leaving the lower mounting to you.
DC2 Fitment Example - Note: The top of radiator can tucked under the upper core support but core support and latch assembly must be removed and radiator tilted forward 6°. OEM mounts are used to get this fitment.
EK Fitment Example - NOTE: The top of radiator can tucked under the upper core support but core support and latch assembly must be removed and radiator tilted forward 6°. ASR brackets must be used in order to get this fitment.
Terms associated with radiators...
SINGLE PASS RADIATORS With a single pass core, coolant enters into either tank, makes one pass through the core, then exits through the other tank.
DOUBLE PASS RADIATORS With a double pass radiator, the inlet and outlet are located on the same tank. There is an internal baffle that separates the tank in half. Hot coolant enters the inlet and is routed across half of the core and then back across the other half of the core before exiting the outlet. Double passing is also used for efficient packaging and plumbing of the cooling system.
OPEN SYSTEM An “open” system means the radiator has a radiator filler neck and cap built into it.
CLOSED SYSTEM A “closed” system means the radiator does not have a fill neck and cap on it and likely uses a remote surge tank for filling. “Closed” systems are typically used when the radiator is not the highest point in the coolant system.
CROSS or HORIZONTAL FLOW Coolant enters a cross flow radiator on the side tank and then flows across to the other tank.
DOWN or VERTICAL FLOW
A down flow radiator has upper and lower tank. The coolant flows into the upper tank and down to the lower tank.
