Default Re: Update E-F/SA Bird Build...

Well, i made it 3 rounds this weekend... and by Muncie's timers, i ran a 11.477 on one pass, and 115.86(tickets are downstairs, pretty sure thats the mph) on a pass...but most were in the low 115.xx range. I also clocked a 1.497 60ft on their clocks...the car did seem to be leaving well, but i wasnt showing any real ET gain from it. Not sure who's timers are right, but i like the 1.497 better than 1.533...hehe Best ET in the 1/8 was 7.22, with most in 7.23/7.24 range... Track was not good early on, but came around... I think maybe a few degrees timing and i may be a tad rich, in the secondaries... 1st gear seems to get over with quickly, but 2-3 seems to be longer than it should... need to change oil, run valves, put new slicks on and get ready for indy Also, keep in mind, im only leaving at 2500, because much higher, the secondaries start to come in... i wonder if i put a regular plate on the carb, i could possibly leave higher on the converter? And if couple more degrees timing, and a slightly leaner fuel charge, the engine would pull to 3rd gear quicker... im also only shifting at 5700-5800 both gears...Since i was racing, didnt want to experiment with 2-3 shift point...
