[Fot] TR6 gearbox

[greg]

   A couple of people mentioned the number of speeds in a TR box 
referencing that 4 speed + OD = 6 or 7 speeds. Unfortunately, SCCA never 
recognized the OD as "speeds" until sometime in the  90's. They had 
wording in the GCR stating that 4 speeds plus OD still equals 4 speeds 
in the gearbox. This kind of convoluted logic has mostly gone away. We 
are now allowed 5 speeds.
   With the torquey big TR motors, using 5 gears would most probably 
result in lower lap times. Most Production and GT racers are using 1st 
gear in a 5 speed as a paddock gear. Around PIR, Firebird, and 
Buttonwillow, using 3 gears is faster than 4 with a lot of close ratio 
boxes and production engines. Most of us clubbies shift too often and at 
too high an rpm but it sure sounds good. Sometimes on board data 
aquisition ruins a good thing.
