Please don't change the format after I've already sent the entry fee in the mail. I have no problem running 3 back to back runs in the 11s. True street cars should have no problem running back to back. That is one of the reasons I signed up for this race. If you leave long cool down periods between runs, people could bring almost anything out to run then most of the street cars that are going to run will have no chance at all. I think if you give it a little more time the field will fill up.
