 Thanks,  Jerry

BTW I used to be against louvers as being bad for aerodynamics.
I now think they are the lessor evil. Radiators MUST be unobstructed
on their back sides.

What?  You mean my Louvers are now acceptable and I can stop covering them

By the way, I presume I'll see you at Tracy's late October?

Not in your case Ed :-) If your rad was right next to them I would
like them. Your rads dump into the cowl and then the air tries
to find it's way out. You would be better off with a large cowl flap.
Also I think your rads would work better or could be smaller if 
they were not so close to the gear box and the engine.

Yes I will try to be there in Oct.

BTW how are you coming with your PIC programming?
Are we going to see an aerodynamic pressure data acquisition system
any time soon? How about an engine data display using outputs
from Tracy's EFI and other sensors? If you do something like that
please log the data in EEPROM for later RS232 download. That would be 
very useful for trouble shooting cooling and other problems.

I'll be your first customer... sight unseen.
