Just rolled in from 5 days at Mid-O. Was really a great event. 3 days with BMWCCA and 2 days with Chin Motorsports. Fred Switzer & Jason Tower were paddocked up for both events. Rich Bratton and Kish paddocked up with us for the BMW weekend. I had a hangover every morning.
Also there were Scott Barton and Anthony Mag, neither of whom I’d ever hung out with before.
I had some engine problems (shocker) but worked thru most of them. Engine was missing at high rpm at WOT. High rpm and partial throttle was ok. Mid rpm and WOT was ok. Only the combo of high rpm and WOT was bad. I replaced everything that was ignition related. A smart guy looked at my plugs and said that purple discoloration was a sign of pre-ignition so I drained my gas out and tried 110 octane race gas. I racked my brain trying to come up with a theory where only the combo of WOT and high rpm caused the missing. And not every time either, occasionally the symptom would not occur.
The problem turned out to be alternator grounding. I think. The bolt under the alternator was a little loose and that allowed the alternator to shift forward and back a little bit. Not such that the belt would loosen mind you, but just enough to allow the alternator to shift forward and back. I tightened that up and the symptoms got better by 80%. Sadly, not 100%. I never was able to get the engine to run really well at high rpm.
I started the two events on worn tires but wasn’t quite able to cord them before hanging it up on the 5th afternoon. I thought sure I’d be able to cord them. Guess I wasn’t driving as hard as I thought. God knows I was sliding ALL OVER the place.
Mid-O is lots of fun. It had been a while since I’d gone to a new track. Mid-O has some turns that require balls, some twisties that require precision and rhythm, and a fair amount of run-off room. The only bummer about the place is no camping.
Mid-O is a 14hr drive for me, assuming one consumes an hour with 3 stops for gas and coffee. I left yesterday around 4PM and got to a rest stop at the SC/NC border at 0100. Caught some racktime and headed out again at 0500. Trailer got a flat in Columbus so that cost me some time, and then rolled into the house this morning about 10.
This was my first time towing over mountains. I learned that descents can be a little tricky.
My flat was the 3rd one for me and my trailer. Anyone ever think about putting a tire pressure monitoring system on their trailer wheels? I’d hate to lose 2 trailer tires because of a single flat that went unnoticed until it’s buddy failed under the additional strain. The last time I got a flat I could tell that the trailer wasn’t handling quite right, but it was subtle enough that I didn’t stop to check it out. This time I couldn’t tell at all, a passerby alerted me to the problem.
