Just a weekend after Road Atlanta, I attended another NASA event - this time at Sebring International Raceway! Even with the hot Florida summer attendance was full. The car was definitely down on power in the heat, but it was still a really fun weekend. Here are some photos:
Unfortunately my luck ended on the last session of the second day. I miss-shifted after turn 7 going from 3rd to 4th gear. Turns out I went to 2nd for a split second, causing an overrev. The pics below illustrate exactly what happened to 6/8 of my intake retainers. You can also see my bent valve on cylinder 4. My compression numbers went from 240 across the board to 120/210/180/0. As soon as I ran compression I knew I had bent valves, even before I popped the valve cover off.
The good news is I did not drop a valve. After taking off the head this past weekend the pistons have no scars and cylinder walls are buttery smooth. A spare head is in the mail as we speak. Turns out the car will only be down for a few weeks. VIR at the end of August is still happening!
While I'm down there I'm going to go ahead and do a few upgrades: ARP studs, new Koyo radiator, and a full gasket kit.
