Did a bit over 100 laps in all which isn't all that much. However did a couple sessions of 15 or more laps and other than frying the stock brakes, the car performed flawlessly with oil temps in check. Temps were cool out so that could be a important factor so I will keep my eye on oil temps as it gets warmer out. Maybe this ESS kit is just over-enginerred.
Here in Texas, I track in 105 degree temps, sometimes on track temps are 110+ so this may not apply for folks in cooler climates.

But you are basically stacking coolers in front of coolers. There's no added volume of air so your radiator is now seeing air heated up by the intercooler. There's just not enough cooling on a stock motor. More HP = more heat. I've learned this. Many FI companies advertise their kits being used on the track. That's great and it works for them. I'd discuss with the company first before purchasing and make sure they understand the service demands the car will see. What I was told on my E46 330 kit is that it wasn't not designed for heavy track usage. For me that's a total game changer.

From my experience and looking at cars...you don't see a lot of advanced drivers and instructors driving at a lot of events that have forced induction. There's a reason for that.
