Great info! I’ve been racing with 727s for over 20 years and have not experienced anything like the explosions shown in the video. But I follow a specific set of guidelines. First the transmission is built right. Always, always, always start burnout in second gear then immediately shift into third. Don’t allow the rear tires to ‘grab’ under power during the roll out. And in the shutdown area I just let the car coast in 3rd, I don’t try to throw it up into neutral. Once the car slows enough via braking, and I turn off onto the return road I’ll upshift into second.
