Hi - I race a 1991 Lola T91/90 Sports 2000, it's a sports racer powered by an engine originally used in the Ford Pinto. The car is much sexier than I'm making it sound! The motor revs to about 7000rpm, and at the moment I use shift lights on the dash to help time the upshifts. I'm sure everyone has seen the lights, anywhere between 3 and 12 of them, different colors, usually run left to right, and they light at 200 rpm increments. Last one goes on at 7000rpm. Lots of products available (search shift lights). Now in the heat of the moment it's easy to miss the lights, and glancing down in a racecar more frequently than required is a bad idea. So I've been trying to find an audible shift system, where instead of lights a series of beeps or a tone is transmitted to an earpiece worn inside the helmet. No one seems to make one. So I'd like to build one, or have one built for me. Any thoughts on where to start? Car has a coil, and most shift light system take the RPM input from there.
Any help greatly appreciated!
