Time to liven-up this forum again!
It's been nearly 1 year since I last ran at COTA. My 2020 rebuild drowned in its own PCV oil vomit and glazed the cylinders/rings before I got the vent plumbing sorted out. What started at 449hp Feb '21 ended up at 391hp last October '24 with close to 25% ring leakage, but I still managed a Personal Best of a low 2:32 at COTA. Pulled the motor in April, but the no-pressure hone/re-ring was just finished near the end of September. We used honing plates this time, changed 1 pair of rod bearings that had a small speck embedded in one half, bumped the compression not quite a point with thinner gaskets and had to install some shorter pushrods to keep the Gen 3 rockers happy.
Hoping to have the car back together in a few weeks, shake it down a couple miles, then hit COTA again for a Sunday session first part of November. Another weekend or two in Dec/Jan to hit my sub-2:30 goal for the blue car, then it switches to mostly road duty while the racecar becomes my primary track weapon.
I've been tinkering with the racecar a few hours per week in the meantime going through the fuel system, oil and cooling circuits to my liking. Suspension is getting freshened, but the engine will need to come out with 2 holes having very low compression from stuck injectors.
