I'm happy to report that we're getting close to being prepped for the UTTC this coming Friday. I performed an around the neighborhood test this afternoon and the modifications all seemed to take. We'd enlarged the header tank substantially, re-routed oil cooling, put an electric fan on the oil cooler, wrapped the headers, put on higher rate springs, and made some adjustments to the instruments, screen, ignition, catch tanks, and coolant bleeds.
Interestingly, we have two MSD boxes and two coils on the car that are redundant systems and selected with a switch. Both will run the car, but one MSD, unit A, decided that it would no longer drive the tach. Wiring is all sound and the unit used to drive the tach just fine, but has since decided to quit. Probably will need to replace that unit soon since that might be indicative of impending failure.
Also installed one of the new GPS speedometers from Speedhut. It works great. I can't tell any difference in it and a non-GPS unit and the installation was very simple. Quite pleased with it. The unit also provides max speed, time, direction, quarter mile, 0-60, trip odometer, and has signal indicators for turn signaling (I'm not using them yet). Extremely small, compact, and light. Highly recommended.
It isn't a GT40 we're running at the UTCC, but we can't seem to get any GT40s in the area to join us on the local track events. Bring em out guys!
