OT: Barn-find flat six Tucker on a dyno

Preston Tucker built just 51 examples of his innovative rear-engined car. Today, 47 are known to survive. And for perhaps the first time ever, we finally get to see one run on a dyno to learn exactly how much power it's making.

Tucker #1044, recently purchased out of a barn in Ohio, was discovered in incredibly good condition. Showing just under 8000 miles on the odometer, it's served as a reference point for other Tucker restoration projects.

Now, #1044 is undergoing a restoration of its own. And the folks at Preston Tucker LLC put it on the dyno to see how much power that 5.5-liter water-cooled flat-six puts out.

The baseline numbers, according to Preston Tucker LLC, were 94 horsepower and 221 lb-ft of torque at 2700 RPM at the wheels. As Raphael Orlove at Jalopnik points out, that's down a bit from the 150-to-160-hp figure referenced by many Tucker historians, but it shows that the priority was low-end, low-stress torque. The engine was derived from a powerplant originally designed for a Bell helicopter, so a screaming redline wasn't in the recipe.

We continue to be fascinated by these amazing, unusual machines.

500 cubic inches will make torque!! gg

A loooong time ago Mr. Nethercutt (Nethercutt Museum - [www.nethercuttcollection.org] ) acquired a Tucker and someone who worked at the Museum told me the rear suspension used rubber blocks that had failed. Many owners just welded up the suspension parts to make the cars roll, but NOT Mr. Nethercutt. He contracted Goodyear products to make replacement rubber blocks (it took a few tries) that worked and for awhile he had the ONLY Tucker with correctly functioning suspension.That's the story I got, and knowing the quality of the Netercutt collection I have no doubt it is true.

Sadly Mr. Nethercutt has passed on.

Several local Corvair Clubs were guests at Dave Cammack's garage in Alexandria, VA. He had THREE Tuckers, and the test mule with the 13" tires and dual torque converters.
I talked with him at length about his cars, including having parts made. He had most every Tucker parts drawings upstairs in the building. He did have a rear control arm assembly from a Tucker that met its end in a fire!

The three, the mule, the engines and transmissions (did I mention he had LOTS of parts?) and all the documentation was donated to the Museum formerly known as AACA Museum (long story there).

Oh, Corvair content...: One one of our visits, he said he liked seeing us driving our Corvairs, as he cold not drive his tuckers anywhere except outside to wash them. eye popping smiley

South Coast Corsa (Los Angeles) used to meet at a bank's community room in Inglewood. One Sunday, a local rolled in in his Tucker; he thought we might be interested in seeing it. We were all over that car like stink on a bug!

At the time (pre-movie) Tuckers were just very interesting old cars. His had green shag carpeting; all the way up to the windshield on the right side (aka "Safety Cell").

I remember seeing one for sale in the LA Times Classified's: $5k! Who would have known...

I visited the Cammack collection in December 2011 and for the first time actually saw one in person. David was quite an interesting person and was willing to spend all day simply talking about the cars and the hobby in general.

After his passing, as prearranged, the collection went to the AACA Museum in Hershey PA and they have done a very good job at presenting it there.

I too visited David at his place. Twice...once in 2009 and once in 2010. At the time I was living about a half-hour south of him. I enjoyed talking with him and poaring over all the engineering documents/blueprints he had upstairs for hours and hours. With his assistance in 2009 I wrote the Wikipedia pages on both Preston and on the Tucker 48 car. Cool that today aside from some minor content additions they are largely unchanged.

I have always been fascinated with Tucker. Did you read the new book that came out recently about Tucker? I read it this past summer. I know that David helped with some of the information in the book, he mentioned it when I was talking with him in 2010.

Nick,

No I have not read any of the books. All I have seen is the DVD I purchased from David to support the AACA Museum. Actually I bought two and gave an additional cash contribution at the time. After spending the day looking at his collection I considered it a good investment.
