Default Re: Helmet style distributor 85 to 60hp

Its not impossible to make a helmet run more rpm , especially the later version model 68s or 11 A , The advance curve was quick and topped out at 22 degrees etc. The use of individual contacts helped a lot. With a small cam and seperate contacts we can get them up and over the 5000 rpm mark and with some special work maybe above 6000 etc.
However thats why Kong , Harmon Collins etc made up the dual coil units . A harmon Collins dual coil will pull 7000 plus all day long..
