Re: just a quickie , an maybe I am nuts
How do the hotrod guys do it?
Is the fuel injected into the exhaust manifold? I don't think the motor could be a "bomb" unless you fed it nitrous to the intake.
If the flames only came out the exhaust I don't think it's that dangerous if you can control it. And yourself.
I realy like this idea.
Of course you would have to use disgression about when and where to use it LOL.
I've helped put a "smoke generator" on an ultralight once. Just added a small steel tube to the exhaust manifold and plumbed it to a small garden sprayer loaded with transmisson fluid.
