Ponyboy said:Nah, it wasn't that I couldn't tell a difference. It was that the car overheated b/c it wouldn't open. I put the stock version in and forgot about it. IIRC, I'm really not quite sure the Mugen version sealed properly.
Ponyboy said:In my situation, my NSX had extenuating circumstances re: cooling. It seemed like I've always, in some fashion, been chasing an overheating issue. It stopped with the replacement of the stock and, really, damaged radiator. In some places it looked like someone had threw a baseball at it. So my decision came from a OE rad or an huge NASCAR rad. I decided I didn't want to worry about overheating anymore. Kinda like I don't want to worry about overheating my braking system anymore either.
Concerning the Mugen thermastat, it may very well be a good product and I may have got a defective version - wanted to say that.
Basically with the rad, I went to Defcon 5 and never looked back.
