I spent the last three days watching a World Racing League event held at COTA. WRL has a lot of people defecting from spec and has a growing boxster presence. There were 9 Boxsters at this event and that was the most I've ever seen at one WRL event. The first day was test&tune, but the next two days were 8 hour races in the rain. The rain was slightly heavy but was very constant and didn't really lighten up until about the last two hours on Sunday. It seemed like this was a big learning event for lots of teams as the rain was affecting most if not all the boxsters. The first and most common problem was windshields were fogging up. To save weight, everyone takes the HVAC systems out of these purpose built race cars.

Crews were trying everything to keep the windows clear enough to see through. Some guys carried towels with them and would wipe down the windshield on the straightaways. Then people started using shaving cream or dishwasher soap. One team would swear by soap and the other would swear by cream, but they both had to work on how much to apply. By Sunday some had added tubing and fans to help defog the windshield and no one seem to have any fogging issues on Sunday.

Another problem that started to affect the boxster within about two hours of racing was the MAF getting wet. A handful of guys were having running issues and it dint seem to matter what air filter you had. Stock, K&N, 987, they all had issues. I think constant 6-7000rpm racing in the rain sucked in lots of moisture. Some guys unplugged the MAF while others changed filters. This guy added a shield in front of the intake.

In defense of the boxster. The rain was affecting lots of vehicles MAF sensors. Not just Porsches
One crew also had their immobilizer get wet because it was still under the driver's seat. They got lucky and were able to dry it off and put it back in.
