This is from the April 2001 Grassroots Motorsports magazine. The purpose of
one of the articles was to see what could be done inexpensively to improve
the performance of a 1973 MGB-GT. All testing was done on the dyno at Baker
Engineering in Nunica, Michigan. 15 different tests were performed, twice
each, to see what worked and what didn't. The distributor advance was
checked for proper operation and the car tuned to factory specs. The
resultant HP was 56.8. Next, a PerTronix Ignitor ignition was added and the
test run again. The max HP was 61.1, an increase of 4.3HP. Then a MSD 6A
system was added, giving an additional 1.6 HP for a total max of 62.7 HP.
Any comments?
