[Healeys] Flywheels

[healeyguy at aol.com]

Slightly off the lighten flywheel topic, well maybe not. The engines we 
are mainly talking about, the Austin 6 cylinder, is an inherently 
smooth engine. Not a V12 but an inline 6 generally has good balance 
characteristics. Less cylinders has added issues especially in the 
older designs. To the point, I use a BJ8 flywheel on our BN2 which is 
substantially lighter than the stock BN2 unit. IM(not so)HO there is a 
difference in seat of the pants enjoyment especially on acceleration 
with no noticeable change in traffic or at idle. Of course not every 
one drives these cars the same (not even on the same side of the road) 
but I don't think anyone is running a 12 pound flywheel on the street, 
perhaps some of you guys in Australia!

Ken,

I disagree. I cannot tell any difference in smoothness of engine. It 
does rev
noticeably quicker than my BJ8. Does it make a difference in
acceleration/performance? I have no data but it feels quicker.
