WR35TC GTR GR6 TRANSMISSION INTERCOOLERWR35TC-F Pro Pump, For serious track work su nagtrocWillall WR35TM temperature limits?Our Price: $2995.00

Designed to deliver cooler operating temperatures to improve reliability and longevity of the R35 GTR GR6 Transmission, WR35TC is ready to fit your GTR. Pictured is a look at WR35TC from under the car showing the unique high quality billet aircraft aluminium finned sump that works in conjunction with a sophisticated pump and cooling core to achieve the best possible cooling result. Highly engineered and with every consideration put into its design WR35TC the thermostatically controlled promises to reduce transmission operating temperature without the pressure control problems other GR6 cooling system designs have encountered.
NEW RELEASE: WR35TC-F Front Mounted transmission cooler also available. Designed for those that run aftermarket exhaust systems on their R35GTR the –F front mounted cooler option stops the cooling process being interrupted by heated air from the exhaust system. When GR6 transmission cooling with an aftermarket exhaust make sure you pick the WR35TC-F no cost front mount cooler option on the order form (see WR35TC pictures for actual cooler views).
Coming in each and every WR35TC kit are the following components:
Billet Aluminium CNC sump with Willall Racing Transfer
Bar and Plate 450mm x 100mm x 75mm cooler core custom end tanks with -6 fittings
Braided lines and -6 / JIC high pressure fittings (around 4 feet)

TESTING

Subaru WRX driver looks on at impending doom about to be lapped by the Willall Racing R35 GTR
Testing the WR35TC GR6 Transmission Intercooler correctly was always going to present a challenge, as with fluid handling it's not as simple as 'switch the cooler on its cold', 'turn it off its hot'. Also the car has to be driven HARD, there is no point in taking it easy as the temperature of the transmission is directly proportional to the lap times.
The Willall Racing GTR was tested to the limit of the RE0570 tyres and brakes (Endless pads were used). Our test driver is very quick in the car due to lots of practice and could reasonably argue our 1:17.5 lap pace at the South Australian Mallala circuit is similar to 2:10 or so at a track like VIR. Over 1.5 tanks of fuel were used in the test session showing exactly how hard the GTR was driven.
NOTE: Lap Temperatures recorded are with the warm up and cool down periods removed from the data
Test 1: WR35TC Cooler Status ON
A test to check the outright cooling ability of WR35TC and find the 'stabilise' point of the transmission temperature
Ambient: 75F - 24°C - Trans Start: 195F - 90°C
Lap1: 215F - 102°C
Lap2: 226F - 107°C
Lap3: 237F
Lap4: 240F - 115°C
Lap5: 242F
Lap6: 241F - 116°C
Test 2: WR35TC Cooler Status OFF
With the cooler turned off this is the raw data of temperature build up in the GR6. It gives you an idea of our punishing conditions
Ambient: 75F - Trans Start: 194F
Lap1: 220F - 104°C
Lap2: 231F
Lap3: 248F - 120°C
Lap4: 265F
Lap5: 272F - 132°C
Test 3: WR35TC Recovery OFF and ON
Letting the transmission reach almost critical temperature we then turned the cooler on to check temperature recovery
Ambient: 76F - 24°C - Trans Start: 181F- 81°C
COOLER OFF
Lap 1: 231F - 110°C
Lap 2: 240F - 115°C
Lap 3: 252F - 122°C
Lap 4: 264F - 128°C
COOLER ON
Lap 5: 261F - 127°C
Lap 6: 255F - 123°C
Lap 7: 252F - 122°C
Lap 8: 250F - 121°C
Lap 9: 249F - 120°C

FRONT MOUNT: WR35TC-F Cooler assembly sits in the spare frontal intake duct on the R35GTR. Massive airflow is available in this position which facilitates the use of a compact cooler core that retains the factory washer bottle position
