Hey Gary

Do you have any pictures of your
EDM 830 installation on Allens Tiger?

Can you install them flush?

Subject: TeamGrumman-List: cranking pressure
From: teamgrumman@AOL.COM

Cliff, here's one for you to chew on.  


I've been doing both leak down and cranking pressure tests now for about
 a year.  Tigers generally run 130-135.  One Lycon Tiger was 145 across th
e board.  Cheetahs run about 125 to 130.  


I did a cranking pressure test on a Tiger last weekend with 


(1) 125 psi
(2) 123 psi
(3) 142 psi
(4) 120 psi


I redid the #3 4 times and got the same value.  Something is changing the
 valve timing events enough to cause this difference.  I didn't go any fur
ther into it.  The leak down tests were 79/78/78/78

Subject: TeamGrumman-List: horizontal braces
From: teamgrumman@AOL.COM

I delivered the plane Saturday with the new horizontal braces.  One observ
ation:  it could be me but, I think the horizontal felt stiffer than even
 the one on my plane.  Plane flew well.  I did some steep turns and pulled
 a couple of g's.


We'll see.


I have 3 more planes with cracks.
