FBM Dual Pass Radiators - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

FullBlown · 05-02-2014, 01:34 PM

We started designing a dual pass radiator months ago and were debating if we should release them or not. The reason being is that our standard radiator with our aluminum shroud and Spal fans been working flawlessly.

I feel this would be geared towards the hard core track guys who are looking for the absolute best cooling solution possible.

We have completed the test units and will compare back to back vs our single pass.

A dual pass radiator passes the coolant across the radiator
twice. This places both the inlet and outlet on the same side of the
radiator. Double pass radiators are more efficient and works well for both street and racing applications. This will be sold as a complete kit with both radiator upper and lower radiator hoses.

So this will also fit a street car well without us having to sacrifice the A/C system?

Great price considering it includes both silicone radiator hoses.

I'll probably get evils from others for saying this, but i think based on the quality and innovation of a lot of your parts, you under price them.

Shhhhh!!!

xjohnx · 05-02-2014, 06:45 PM

How does this effect pressure? I recall reading that double pass radiators take 16x the pressure to flow the same volume of coolant, resulting in reduced flow. Is that the case with these or is that a non-issue?
