I don't think I like the hood scoop we installed. It leaves the air filter totally exposed to water, and doesn't seem to improve much. I think louvering the hood will be the way to go. I also think a proper cold-air intake will be much more effective for sucking in cold air. The MR2 guys at rallycross did get a kick out of the scoop.
We're modifying the hood to help with underhood temps and cold air intake, and looking forward to the North Nevada Rally on June 20 near Reno. It should be a hot one, so we'll know for sure if the fixes work.
On Saturday we were plagued with alignment issues. The front end was severely toed-in, which made the car not want to turn in, and carved the front tires into a nice sawtooth tread pattern. We adjusted it by sight to slightly toe-out, which greatly improved things... Until they got worse. One of the outer tie-rods "went bad", and made steering kind of loose.
Once we found and tightened that, things momentarily improved, then all of a sudden, THUNK! It got horribly bad. The car would pull one way when I accellerated, and dive the other way when I let up or braked. We white-knuckled through the final 2 stages of the day at about half speed and back to the service area where we discovered a front control arm bolt had come unthreaded and was barely hanging in the hole. The control arm was flopping around on the loose bolt making the steering prety random, especially on the rough roads. I don't know how much further we could have gone before it fell out completely, which would have been catastrophic.
We ended up in 3rd place (just 23 seconds behind 2nd) for Saturday. After replacing the worn tie-rod and torquing the control arm bolt to spec, we went back out Sunday morning. I was still pretty flustered from the first day, and kept waiting for something else to fall off the car. Even so, we managed to take 2nd in class.
The new car has good power when its running. It was difficult to start as the day went on and the weather warmed up, and I had to babysit the throttle to keep it idling. We haven't really tuned it on the low-end, so I kind of expected that. We should be able to get it going by Oregon Trail.
The sweep crew yanked us back onto the road and we finished out the stage at moderate pace, avoiding a DNF. That makes us 3 for 4 so far this year, with 2 rallies to go.
Our service crew was the best! Friday's Arctic theme was a welcome relief from the Idaho heat, and Saturday's Hawaiian Luau took our minds off the "detour" into the trees. I can't wait to see what they do next time.
