Streetsnake There are a couple of things you should do between rounds of running, First off open the hood to help remove the hot air from the run. After running the quarter mile on the return road run about 10-15 mph and turn on the coolant fans to help cool off the motor. If you are going to hot lap the car leave the fans on. Check and may sure that your charging system is up to the power needed to keep the motor, ignition, coolant fans, and battery charging at idle. If you are in the neg side of the amp meter, you are killing the battery. MSD needs 10.4-10.5v while cranking to start the car, anything less and the car may not want to start hot. Fuel system is another BIG issue if racing. As others here have said, If you are running small lines, it is very possible you are boiling the gas in the fuel rails. IMO a 3/8" supply line is not enough for a good supply to the injectors. I run 1/2" line to the injectors and 3/8" return. It is possible that your FI system is not tuned to run a little rich when racing, you could be running lean, the computor see the AIR temp readings high and the motor is not getting enough fuel too start. You need to race the car a couple of times and check the fuel maps, timing, and injector pulse rates. The motor coolant temp drops, the AIR sensor reading drops, and the car starts. This may not be caught on dyno runs. Start with a laptop and check the basic numbers. In the future make sure you open the hood between rounds for cooling off.
Rick L. Without slicks, your numbers are good for Sp2 tires. The 60' times will kill you everytime. Mine are about the same as yours. You should end up in the mid 11's at 123-125 mph with slicks, if you don't start breaking things
