Scott Dahlgren asks about interference between the 60 amp B&C alternator

and the

exhaust heat muff on the 320.  



I have the 360 engine and don't know if this makes a difference.  But while

the

components are close, I don't seem to have an interference.  I'm just now

poking

around in that area and have realised that the heat muff can be removed, and

reversed so that the two scat flanges can be oriented in a better way for

plumbing.  My exhaust is the Lancair 3/4 style, probably the same as yours.  



On the subject of taping the exhaust system;



People in automotive have looked at ways to cut the heat loss around the pipe

upstream of the catalysts in an attempt to light them off sooner.  The vast

majority of hydrocarbons emitted from the tail pipe in the EPA tests happen in

the first 60 seconds of engine start before the catalyst has had time to

come up

to temperature.   To my knowledge there are no thermodynamic (read power or

economy) benefits to insulating the exhaust.



A couple of weeks ago someone asked who the manufacturer of my panel mounted

hydraulic gages is.  The Lancair avionics people told me that they are

reconditioned units dating back a long time.  They could not locate a

source for

new gages that would fit.  Next time I talk to Lancair I will ask for the

reconditioning source.
