I'm driving a 2013 Evo X MR if that helps.

I have RREs big stock location replacement SST cooler with a big puller fan, and a second pumped circuit with 2 max length Setrab coolers side by side on crash beam, one max height and one shorter to allow air to radiator--tall one also has a puller fan. These coolers are fed by an RB Racing (made in USA) 2.6 GPM gear pump, and the second pumped circuit can be switched on manually (and both fans come on) or will come on automatically at 190 F with a Setrab thermo switch (for street). Fans on are 1 Setrab relay, pump is on 2nd Setrab relay. Has worked perfectly at 6+ hot CA events. Here is what I learned:

• 3 coolers are much better than 2--requires pump
• 2nd circuit with a high flow pump is better than 1 stock circuit with 2 coolers
• Always switch the 2nd circuit on in pits so temps cannot spike--coolers struggle to counteract spikes in a hot session on twisty tracks and your trans will heat up fine on the track during a warm up lap
• My CBRD radiator helps a lot--keeps coolant temp at 190 max
• The big radiator/oil cooler combination keeps the engine cool, which helps keep the trans cool
• The 2 coolers on crash beam do not prevent the CBRD radiator from working great
• Setrab coolers are worth the extra $, big difference over same sized cheap coolers--I tested
