For all you road racers out there. Have you guys experienced any cooling problems with your NX on a roadcourse that a simple radiator upgrade couldn't fix?

I haven't had any major issues... Yet. The few times I took my NX to the track were during the fall, so temperatures were lower than if it was summer. The first track event I took it to was at Streets of Willow Springs in October. Temps were in the 70's with a slight breeze. Towards the end (last 5-10 minutes) of the first 30-minute session, the temps started to rise upwards of 235deg F. (via Techtom). I turned on the heater full blast for each session following, and haven't had any issues since; temps have not hovered over 220deg (and not over 200deg in subsequent events). I do have the Nismo radiator with only one fan (no A/C) along with Redline waterwetter and about a 75/25 water/coolant mix. The JWT ECU seemed to help quite a bit, and I'm sure pulleys will also help.

The SE-R, on the other hand, never had cooling problems on the track (even on those 100deg days). Still has the small radiator and 50/50 water/coolant mix without waterwetter; but it does have the JWT ECU and UR pulleys.

LOL - every time I drive I never have a cooling problem - I don't have the front spoiler installed yet - and the freakin car will not heat up for anything!!!! I've I drive it for about an hour in 30--40 degree weather - then sit at say a drive through for 5+ mins - it gets near the normal mark - but as soon as I start driving it drops to less than a 1/4 - it sucks *** my winter car doesn't get cold!!!!!
