The first racing event the new RX-7 participated in was on the flat salts in Bonneville. Racing Beat has been a long time Mazda racer, they have previously broken the speed record in an RX-3 with 160.393mph for the G-Production class. The Bonneville RX-7 was outfitted with a Bridge Ported 13B plus 58DSF Weber carburetors, Hall-effect electronic ignition mounted on the eccentric shaft. The car was able to hit 10,000rpm and that was enough to hit 183.904mph on the flats.

I wonder how the people who built this car back in 1978 would feel about the Pica Motors Import RX7 going well over 200 mph.
