Keep the tips for visual effects coming... even if they are not blessed by the AMA. As long as I do not upset or scare the IHRA, NHRA and NASCAR, I could probably do just about any stunt that I feel is not to dangerous to my life and limbs. We talked about doing a little marshmellow or weenie roast skit prior to taking my run...

Now as far as the flame pop effect... I assume the reason I cannot do this now is because the Super Dri Aircraft Smoke Oil I am using is not flammable enough. I have read where the desiel fuel / transmission fluid mix ignites for some people. Can you give me any idea on the mix ratio I should start to experiment with? I do want the flame to blow out to smoke as I thottle up. IS there any danger of the flame flashing back into the tubes?

And the last question. Does anyone have any idea what causes the evenly spaced bright rings in the exhaust of an afterburner? Are these shockwaves or harmonics??? This is probably the coolest thing I have ever seen coming out of a jet engine.
