I had an Air Jammer Road Rammer when I was nine. Made by Tomy (who also released the Air Jammer Cycle Slammer around the same time) and manufactured in Singapore and Japan in 1980, it came with a little bicycle type pump that you attached to the car and pumped the devil out of before pushing a button that released the stored air to a small plastic see-through air motor.
Pumped up to the max the Air Jammer Road Rammer would go flying across a tennis court and would keep going for a good ten seconds or so. It was pretty fast and you could aim the front wheels to go straight or in a circle. It was impossible to over pump the Air Jammer Road Rammer thanks to the safety cap on the back of the pump-up air tank, but it was worth being cautious before you let it go. If it had too much power behind it and went into a wall, you were very lucky if it didn't break into bits. Once the piston was damaged you wouldn't be able to use the toy again.
