Price Fuels used to sell a nitro additive to put in gas cars. Buddy of mine used it in a SLant Aspen. It crushed the top ring lands on all 6 pistons.



Just cause you can do something don't mean you should! Small amounts of nitro in gasoline will drop the octane level like a rock. There's no happy ending to something like that.
On the other hand, a Fuel-Slant is something I've thought about for years. I can't think of any other production engine with a geometry more perfect for burning high percentages of nitromethane than the 225. I think with good parts, 600 horsepower unblown would be a no brainer. I'm surprised nobody's ever built one.
