Radiator: CSF or Mishimoto?

DR_

Well I am not happy with my results with the Mishimoto radiator after getting over 240 degree temps this weekend at the track. The ambiant temps got up to close to 100 but even in the morning when temps were in the 80's it still got too hot. I even went so far as to drain most of the radiator and add back just water and water wetter (estimate 75/25 water/coolant) and that didn't really help. If I slowed down for half a lap the temps would go back down to 220 pretty quickly but that is still too high IMO. My stock radiator got up to 235 temps in similar condition, which was why I went with he Mishimoto. There is no doubt that Mishimoto should be much better than stock but I am starting to thing the condenser is the limiting factor.

When I had the CSF the water wetter and more water didn't help me either, so when I made the switch to the Mishimoto I didn't even bother. To be 100% truthful I wouldn't track my car with either of these radiators. My testing with the Mishimoto is on standby for now I blew up my transmission power shifting with my OS Giken Triple Disc.

I run mine without condenser to optimize air flow. It was about 90 degrees yesterday at the track, and I think coolant got to about 230F during a flat out run but I will check the logs.

I suspect that a properly designed vented hood would help quite a bit in that regard as there is most likely a bit of back pressure behind the radiator if the air has nowhere to go.

I'm convinced this would solve everyone's problems.

I tell a lot of the 370Z drivers I see at the track this same thing, and we've seeing up to ~10 degree drops in temps with vehicles with vented hoods. Exit airflow is key in a proper cooling system.

On another note, I'm currently sitting at my factory, and I'm discussing with my egineers several ways to make our unit even better. Perks of manufacturing your own product

We'll be testing our current unit against our new innovative design through MotoIQ.com.. Stay tuned for results...

I'll take another radiator and test it out ;-)

Curious to see the new design, and been doing data logging myself as I am adding a vented hood soon.
OEM Hood v Seibon TS Testing

Plenty more data coming, been stuck as excel is running into data limits and such.

If I can help, my excel at work is limited to... 1.3M rows and god knows how many columns

The issue I am having is we have excel 2007 (plenty of rows/columns) but when trying to graph the data points it limits me to 30k points. We are in talks to upgrade the office to office 2013 which "should" solve this problem.
