[Healeys] Lightened Flywheel

[Bob Spidell]

Falls more into the category of 'disappointment.'

I've sometimes wished I had a lightened flywheel in my BJ8, but I think 
the lower inertia/torque would be even more of an issue with its 3.54 
rear end (yes, it takes a tad more finessing of the clutch pedal than 
the 3.91). This is the classic argument of torque vs. horsepower (John 
and Kees are both correct, there's inertia and torque, both give more 
pulling power, which is what we're talking about off idle). In my BJ8, I 
can let out the clutch slowly and it will creep away from a standing 
stop, if I do that in my Mustang, with 475HP and 425lb-ft of torque 
it'll stall every time; it doesn't start really pulling until over 
3,000RPM (but will pull in a straight line to the rev limiter at 7,400). 
Yes, the Mustang is heavier, by a little over 50%, but has more than 
three times the HP of a stock BJ8). But, if you want torque, my dad's 
old 4-banger Ford tractors would best them both in a tug-of-war.

I can't however, think of a reason why the OD would be affected; it's 
either engaged or it isn't. If the cone clutch was slipping that would 
certainly cause issues.
