There must have have been a helper that sat between the engines to operate the front set of pedals! :-)

That was probably meant as a joke..... Just leave the bands out of the front power unit and couple the two crankshafts. I remember there was one in Az a couple of years ago.

Where is this car NOW ?

The world's First Drag car! Read the writing on the photo.

I believe the photo is part of the Rajo Collection.

Was it McVean may who designed the first Rocker covers for Rajo heads? Prior to that they came out new without covers

Yes it was McVean who made the first Rocker Covers for Rajo

two Radiators and I wonder how anyone could see that front motometer while in operation :-)

You don't need brake or reverse on the front trans. The bands could come out. It would be handy to have H-N-L though. Use N to start the front engine first, use L to start the rear engine with the front engine. From there, it's H on the front all the time to couple the engines one-to-one. The rear trans would take over drivetrain duties.

Remove the bands, shorten the Hand Brake lever start front engine with brake lever in vertical when it is warmed up slowly allow the clutch to engage that starts second engine.

There is a dual engine T speedster (dragster?) at the Smith Museum of Speed in Lincoln Neb. I believe it has dual Rajo's. I was there yesterday but did not take a picture of that particular car. BTW that museum has by far the best organization and display of car and related "stuff" I have ever seen in any museum I have stopped at. Remarkable!

Why not treat that assembly as one straight eight engine? With the front engine's high speed clutch permanently engaged whatever one engine does the other must follow along. The rear engine's transmission remains fully functional for LNH purposes. Cranking the front engine also cranks the rear one. Electric starters hopefully? Use both engines starters together from the same switch.

John Steele is now building a twin-engine speedster. How are you coming on that, John? Got any pics?

Can't wait to see that Speedster in 2 years in Nebraska. Rob might have some competition.

Here is a picture of the oilers cc/craftsman tools build for the Race of Gentleman.

Interesting photos. I do like the idea of using the clutch between the two engines. Have you ever tried to hand crank a big displacement engine? I hand cranked a Pierce Arrow six one time.

When was that Craftsman race held?

Somehow the 70mph in 600 ft seems a little hard to swallow with drag strips being 1320 ft long and back in the 50s, stock cars didn't do a lot better. Also those narrow tires would not have a lot of traction.........

Somebody will just have to build one and see how realistic those numbers are...

Tim -- See my post six clicks above. :-)

There have been a number of these built. Having a transmission between the two engines would complicate things needlessly. I remember there was one featured in one of the period publications, using a single 8 cylinder distributor. I would think that you would have to orient the front and rear cranks' rod throws at ninety degrees apart? It was said that "No more than the usual trouble was experienced from the Ford rear end"

70mph in 600 ft may be feasible. It would take about 75hp at the wheels assuming that car weighs around 1400lbs according to the 1/8mi racing calculator here: http://wallaceracing.com/et-hp-mph-8th.php

1/8mi is 660ft which should be close enough for ballpark estimates here.

With my truck, I am able to hit 0-to-18 in 100 ft. Howzzat ? :-)

Mike, is that Jessie Combs picture in the corner? Dave

Hopefully when Rob Heyen is ready to move on from the K (only a matter of time now being that he's done 70mph), he will set about recreating this car and trying to achieve those performance figures. We're waiting Rob...

I found the original Add I was looking for. McVean selling their patterns for Rajo Rocker Covers. They are also closing down their garage so the engines from the twin engine racer could be those advertised.

Thanks To Jarvis Erickson and Kem Robinson for these adds.

David, you might like to put this photo on your site.

Mark

David, yes that is Jessi Combs in the pic. She's a former hostess of "Extreme Offroad". She's a damn good mechanic. Don.

I would like to know how the steering was set up. It's a long way from the end of the column to the front axle.

Don, I thought so. I've enjoyed watching her (and several other ladies) in several automotive type shows. Dave
