After a longish layoff for the OneLap with Damian (,) it was time for another event with NASA running TT, this time at MAM.

The car drove/ran really well the entire event, with the exception of one wierd session Sunday morning. Didn’t see anything wrong, and it was fine after that so I’m not going to worry about it too much.

The event was my test for the new water injection system I installed, and it went really well. The weekend was an excellent test because of the high ambient temps. On Saturday I ran the first (and coolest) session without the WI system on, and my intake temps went as high as 50 or so degrees C. Second session it had warmed up a bit, but the intake temps were below ambient at 27 C! I did however run through the entire tank of water in 15 minutes though, so I had to crank it back to 50% for the next run. Again the temps were 29 C, even after it had warmed up again outside. I cranked it back another notch and the temps stayed the same for the last session of the day. Overall a resounding success.

We have another even coming up this weekend and I’m going to play with it a bit more. After the temps dropped so much, the tuning was all out of whack, there was way to much fuel, to the point of the car not firing at high RPM. I will need to tune some more.
