Waukesha Rigardo

[KenJackman]

I am looking at a T Coupe that is fitted with a “Waukesha Rigardo” intake manifold. Can someone wiser than me tell if this is a factory cylinder head on this motor?

Looks like an original high head. Never seen a W/S intake manifold. Seen many heads. Very cool.
I see your economy fits all diode cut out. Safer replacement over the cheap, light weight mechanical cut out thats available.
Obviously an improved T. The added fuel filter may give you starvation grief as the tank gets lower.
Safest deal is to remove it & make sure the screen is still in tact in the shut off valve.

Very hard to find intake.

Looks as though that might be an "Improved" Ford - plenty of head pressure for a filter.

Nice intake - only second one I've seen w/mine being the first ! I have the matching "early" head with priming cups on our '19 Centerdoor.

Not a Waukesha Ricado Head. Likely stock head

I wonder if there is any benefit to be had matching that intake manifold to a standard Ford Head?

I don't think it would help much under most conditions. The Ford head is handicapped by large chamber volume and lack of any squish/quench. If the minimum bore of the manifold is larger than the Ford manifold, it might actually hamper low speed performance on a stock engine.

Long skinny intake runners will increase air velocity. It is an accepted fact that longer intake runners will work in a positive manner for engines at low RPM and short runners are good for high RPM motors. How many Model Ts were built with high RPM motors? None.

I find that the Ricardo head offers considerable performance improvement with barely a bump in compression and I would LOVE to try it with a Ricardo intake

I am asking for someone who owns one of these intakes to offer it to me for sale

[KenJackman]

Thanks for the responses everyone. The head has either a “C” or “G” in the casting on the top up front. Does this marking have any significance? I believe it is a “C”

I've been messing with Ts and collecting accessories for a loooooooong time and I've never seen that intake. I'd also like to buy one if someone finds a box of them.

The letters vary quite wildly. Presumably mold letters to keep track of the mold condition to know which of many being cast @ a time need repair or replacing.

Here’s another. I have the head also. I’ve been wondering how efficient theses intakes are with the ninety degree turns.

It's not a high speed manifold. It probably worked very well on a closed car or TT truck running a Ricardo head and 1920s gasoline. In winter, you'd have wanted want a heat stove.
