Description

Details

There might be cheaper setups out there, but there are no better ones. This is the same setup we use on our turn-key conversions, and it's been proven to work both in traffic in Arizona and when strapped to a 500+ hp V8 running hard on the track. Take the guesswork out of your V8 cooling.

Based on our excellent crossflow radiator, this twin-pass setup was designed specifically to mate with the LSx V8 engines. The inlet and outlet are on the same side of the radiator and are the appropriate sizes for the big V8s. There's also a fitting for the steam vent. The twin-pass design makes it very efficient as well. Available for all 1990-2015 Miatas.
 
In order to test the Miata's cooling system, we built a special rig for our dyno. We used it to run a Miata engine at a set load for hours at a time. We tested stock radiators. We tested custom-built crossflow radiators. We tested dual pass radiators. We tried fin densities from 10 to 24 fins per inch, core thicknesses ranging from 16 to 56 mm and fin widths from 6 to 10 mm.
This is the result.

The final design is a dual pass cross flow. This means that instead of having the coolant run from a tank at the top of the radiator to the bottom, it moves from one side to the other and back again. The longer tubes mean the coolant is able to transfer more heat to the ambient air.
 
But there's more going on here than just turning the core sideways. The core also has a fairly high fin density, giving a greater surface area for the heat transfer. Most importantly, our fin width is fairly narrow which means more tubes per inch. Due to this efficient core, we were able to use a thinner design. The end result is improved cooling under all circumstances. Mate it with our V8-specific airflow kit and you'll maximize the ability of your radiator to shed heat.
 
And of course, our V8 Airfow kit comes with it. Two high torque fans pull maximum CFM, even when dealing with multiple heat exhangers - the weak point of low torque "slimline" fans. The fans are mounted to a custom shroud that ensures that all air goes through the radiator core. The shroud also has bypasses built in so it's not a restriction when you're simply using air pressure to move air across the rad.


 Includes radiator hoses and clamps to connect to an LS engine with the water pump outlet on the driver's side. If you have an older engine with the outlet on the passenger's side, contact us for different hoses. You can also replace your water pump with a new one that has the driver's side outlet, not a bad idea on a used engine.
 
 Built in the US, two year warranty.
