I ran 4wd and 2wd mod today. 4wd I fought a very bad electronics gremlin that made the car hard to drive. I got 2nd out of 4 in the 8 minute main. At least the motor worked really good. That 6.5 is a monster. 2wd I was 3rd on the second to last lap of the 8 minute main and lost 2 positions on one jump. I temped inside the building and it was 97 and over 100 outside, so it was pretty dang warm. I am a bit frustrated how the day went, but I will regroup and try again in a few weeks. I ran a 10.5 in 2wd 27/78 in a rb5 and it kept up pretty good with 7.5's.
