Gary, How is this exhaust holding up?
Nice photos. Is that a 12A or a 13B?
That looks like a Mazda electronic distributor, Are you still using it?
Yvon.

Geeezzzz, Yvon....   you must have pulled up this post from a year and a
half ago!!!

I've run the ship personally for about 140 hours after this installation.
I then sold the ship to Maxie Wildes in Ga.   He has apparently put only
about 80 - 100 additional hours on it...

The inconel is the only answer I have found to solve the heat/ banshee noise
aspects of the severely ported 12a.  It also breathed better and got a
better top end from 7010 to 7465 rpms.

I did notice a problem with the distributor on the trailing ignition
activator... the unit began to act erratically, replaced the box in the
distributor and bingo, back up to 7465 again!   (2.85 Ross on a 4 blade Warp
Drive, 745 lbs static thrust)

I called her the steroid Hummingbird!!
