Billy - Agree with you 100%. It's tough to make any kind of real comparison with the PWR. I've been very careful about comparing the PWR radiator. I have too much respect for that company and they are the pinnacle of Aluminum radiators in my mind. With that said, 9Doors is running a vented hood (not sure if ducted but safe bet, to say yes). Also, the MASiV radiator is a copper/brass design. Copper itself has approximately 30% better heat transfer coefficient than AL so there might lie the advantage since Nick ordered a drop-in replacement for 9Door's car IIRC. Copper is also heavier so the additional cooling is augmented by less desirable added weight.
Let's just look at the performance of the PWR in the way I intended to post it (not a MASiV vs. a PWR scenario)
* It wasn't that hot at CVR - Approx in the 80s F
* 9Doors car is a 2000 MY 3.2L NA with a Vented NSX-R Style hood
* It's got the built-in oil cooler
* It is well built/fabricated and of very high quality
* Temps on that day maxed at oil-239, max water-213 which are quite acceptable for the conditions of that day.
My Open Questions for the PWR:
* What if it was 100F+ outside or higher?
* What if the PWR was used in a OEM non-vented hood situation?
I don't think we'll ever get to a point of scientifically testing the one-off products on my car and Jim's for that matter. All we can do, is try our best at providing comparable data. You and I come from a data driven world and it's really annoying when people make claims, so I get it. Hence, if you read all my post I've been careful about making any blanket statements.
All I can do is put my name behind it (and maybe Jim's too) for whatever that is worth. Owners will have to take the risk and try for themselves and see if it works for them. If they don't, then they don't.
At any rate, more proven products for our rare cars is a good thing for everybody.
