NA & NB LFX Cooling Kit

Lead times vary but typically run 6-8 weeks.

A system designed specifically for the LFX using the same core as our LSx radiator and designed to work with factory fans.

The T-3x core is a new FLUIDYNE design which was developed to provide the maximum amount of heat rejection in applications with less than 400 sq. inches of core surface available and where core depth is critical.

The T-3x core is a triple-row core, constructed with our high performance 5mm air fin in lieu of the traditional 7-8mm air fin and 5/8"” flat tube.The 5mm air fin allows us to pack additional rows of water tube in each core… essentially providing the cooling performance of a 20% larger core area.

This new core [called the Slimline core] with our new Slimline 5/8" tube, measures only 2" in overall depth. Saving up to 2" of clearance over standard conversion radiators.

Additionally, the Slimline core is capable of handling significantly higher internal water pressure than traditional radiators with 1” or 1.25" water tubes. The Slimline core is rated at 40 PSI burst pressure so installation of a high pressure radiator cap [28-32 PSI] is recommended which will increase the boiling point of the radiator water from 212 degrees to 230 degrees.

Laminar Flow:
Fluid travels thru any pressure vessel in a column meaning it leaves a area of stalled water on either side of the column’ of flow. The bigger the inside diameter of the flat water tube, the larger the amount of stalled water alongside the column of flow. This stalled water forms an insulation barrier which inhibits the heat transfer from the water to the inside of the water tube so reducing the amount of boundary layer is always a good idea.
By reducing the size of the water tubes and increasing the number of tube rows, the T-3x Slimline core has essentially reduced the overall impact of the boundary layer associated with the Laminar Flow and in doing so, increased the heat rejection properties of the radiator.

Note: The radiator is designed to work with NB style mounts. The radiator will mount in NA cars with use of NB mounts or custom mounting. This is done because of tank expansion. Side tank aluminum radiator expand upwards of .200″ when hot. Utilizing side mounts like the NA can cause additional pressure against the end tanks and cores. NB mounts can be source from salvage yards or dealers. We do have plans to produce a mount solution in the future.

The radiator is match to a GM pressure bottle/reservoir to work in the same fashion as the Camaro and is to be the highest point in the cooling system.
