I have a couple of these manifolds on cars and I really like the way they look. Something I had not noticed before was the possibility of better performance. In a non-scientific way, with the Anderson manifold on one car and a nearly identical set up using a standard two piece exhaust and intake manifold on another T, the Anderson overall seems to run better, more power, better starting and maybe better fuel economy. Cooler air should perform better than intake air being warmed by the Anderson manifold, but that does not seem to be the case.
Does anyone else use this manifold and is there good reason why this would make a difference? Both cars use Z-heads and distributors, with NH carbs.
I will continue to buy the Andersons whenever available just because they are different. The performance improvement when installed would just be a bonus.

Is this a period accessory? Picture?
The ANCO manifold was a period accessory that helped the T running good with the poor grade of fuel available at the time. Here's a thread with pictures: http://www.mtfca.com/discus/messages/80257/84041.html?1236611096
That's the manifold I am referring to. According to above thread, there must have been some advantages as I described.

I've run both the Anco and the Wilmo. I don't think there is any performance or economy advantage, at least not enough to be noticeable. They are easier to install than the separate manifolds. They don't warp like a regular T exhaust manifold.
When these were new did they paint them? Does anyone know what color they came?.......I'm just asking because I was going to redo the one I have..
Sorry if I hi-jacked
Thanks Roger!!
Here's another thread with pictures: http://www.mtfca.com/discus/messages/80257/117504.html?1261548204
Jay's Anco seems to have remains of black paint while several restored manifolds has been painted silver. Guess any paint will burn off soon in the hottest areas.
There may be more durable (and more costly) options available like ceramic coating.. http://www.zircotec.com/
Tom,
After eliminating the hot air pipe and installing a foam air cleaner to my '26 Model TT, I experienced intake manifold icing. Continuous adjustments to the carburetor mixture was the norm and fuel mileage suffered. Installing the ANCO Evenheat manifold offered improved mileage, no carburetor icing, and what I perceived was improved throttle response and performance. My TT is equipped with a Z head, improved grind Stipe 250 cam, Stipe adjustable cam gear, and straight thru NH carburetor. I'm sold on the ANCO Evenheat manifold and running clean filtered air into the engine.

Do you find that the performance is still as good using the filter as it was/is without the filter?
I have not been real successful using the foam type filters that some of the vendors supply. I have never tried a paper filter. Are you using the foam or paper type filter?
And I agree that the Ansco really works well.
Tom,
Foam is the filter element I use and I saw no discernible difference in terms of performance w or w/o the foam element. Currently, I have 5,700 miles on the original foam filter element. Noteworthy, the foam filter is not as effective in filtering dust/dirt. Nor is it as restrictive as the paper filter element.

The Anderson, and the others like it, were made for very poor gas, with even Kerosene.
They don't work as good, and some cases, not at all, as good as a stock, or like stock applications, where the intake is not part of the exhaust manifold.
