I could be wrong here but, I would think a transmission cooler is only necessary if you are tracking the car quite a bit and drag racing as well. For daily spirited driving I dont see how it would be a neccessity, unless you are running the X setup I might be able to understand it. But that being said, it only seems that RA guys are talking about this mod, I havent read about any MR guys running that part. Honestly for $900 I would make the tranny stronger instead of cooler.

general rule is multiply by ten to get the possible crank horsepower from that turbo. this is obviously going backwards, since we don't have actual compressor maps, but we do know it's peak efficiency (65-75%) based on GST's data.
so if the RA turbo is in it's sweet spot at 33lbs/min, then theoretically it can support 330 HP at the crank. given we know drive train loss is 20-25%, you'd be looking at 247-264 whp AT MOST, with full bolt ons, aka the least restrictions.
that data is consistant with what many RA owners are posting on their full bolted stock turbo RA's.

GST motorsports logged lots of info here . the RA turbo flows about 33 lbs/min at peak efficiency and the EVO X 44 lbs/min.

Very accurate. Unreal that we agree on something. Maybe there is hope for us yet

yeah, actually most of the guys with mr's that i know, just run a tranny cooler without question. they consider it a basic necessity and dont feel the need to discuss whether or not they should get one or what effect it may have with or without. i guess when you spend 40k+ for a car, you dont hesitate to spend the 500-1k to keep it going. also, cooler transmission=stronger transmission, and if they were to do any other updates to hold more, it would just generate more heat, further facilitating the need for a cooler
