The physical units are being built currently but here is the final design of the FL5 WOT spec triple pass radiator with transmission cooler! There is also an FK8 version in production and it will in essence be the same with different mounting points specific to the FK8.

PWR will also be releasing their own spec here soon. The WOT spec will have two primary differences:

1) More track oriented custom core spec: higher fin density, and special fin louver angle to further improve heat transfer.

2) Integrated bracket for optional transmission cooler: Built in provision on the back side of the radiator to easily add an optional transmission cooler to further reduce coolant temps by unburdening the coolant system (the OEM design uses the coolant system to cool trans fluid via the heat exchanger on the front of the transmission).

The placement on the backside of the radiator is to minimize interference with the radiator and maximize efficiency.

The idea WOT spec will be the ultimate level stock replacement radiator available.

This will fit just like the current PWR single pass radiator. No modifications needed, works with the fan and works with various intakes.

If you would like to order either spec contact me and I can set your order up. I will be the only vendor offering the WOT spec.

Price is $1600 without the transmission cooler attached (but can add it later since the bracket is on), $1800 with the transmission cooler, lines, and clamps. $120 for shipping, so $1720 or $1920 depending.

PWR spec will be $1400 plus $120 for shipping so $1520.

You have the option to plumb the transmission cooler in 2 ways: 1 is to integrate it with the OEM heat sink piece to maintain OEM warm up using coolant, or #2 is to completely bypass the OEM heat sink but at the cost of losing OEM warm up.

FK8 version will require the removal of the passenger side fan, but in talking with the PWR engineering team they feel confident this will cause no issues on the street and on the track it will actually help by removing resistance on the back side. I ran my FK8 daily and track for 2 years without the passenger side fan with zero issues even in 105+ temps in the Reno summer.
