    Is that a 4 or 8 cylinder?

    It’s a straight-eight from the 1930s.

    I don’t think I have ever seen a straight-eight. The car looks European.

    It’s a European racing car (still functional) photographed at the Lignières antique car rallyStraight-eight engines were used in a variety of high performance and luxury cars in both Europe and the U.S. in the inter-war period.  After World War II, progress in making aviation fuel during the war led to automotive engines being designed with a higher compression ratio to produce more power and improve fuel efficiency.  Higher compression ratio increased the stress on the long crankshaft of a straight-eight and motivated its obsolescence in favour of the V-8.  Also, a V-8 was more compact and did not require the long engine compartment of a straight-eight, which fit better with postwar styling.

    Straight-eight engines continued to be used in auto racing until the mid-1950s.  Mercedes won the 1955 Formula One championship with their W196 straight-eight.

  2. I didn’t know radial engines came in odd numbered cylinder rows. They fire counterclockwise and the odd cylinders are in sync as the even are in sync.

  3. Love these pix!  Reminds me of the most fun car I will likely ever own: a 2003 Anniversary edition hand-built Mustang Cobra SVT.  A memory now, a victim of having too much hardware and camping, alas.  10psi Eaton supercharger modified by yours truly, as gas mileage concerns are for sissies in the USA, plus much else.

     

    That Redwood you could drive though is now gone.

  4.  

    The c1946 Ford coupe convertible is parked at the main entrance of St. John Kanty prep, Erie, Pennsylvania, in 1946 or 1947. The car is okay, and so is the architecture, but really look at those two good-lookin’ laddies!

    The one on the right in cool shades is 23 years old. To the left is his younger brother, a high-school student. They were very far from wealthy, but they maintained a decent appearance out in public. Such were the standards of the day.

    The architecture is heritage from the past; the car is representative of the future; the young men are properly prepared – poised –  to preserve the heritage and stride into the future.

    What size engine, Trin? HP?

    It’s a hand-built, balanced SVT engine, good for about 7k RPM, and is loosely based on the 4.6l Ford small block found in many standard production cars.  Nothing about this engine is standard, and it had a soft metal tab attached to the engine signed by the two guys who assembled and tested it.  With the mods I made, it was right at 470HP, a lot for a relatively light car, especially coupled with an indestructible and compliant short-throw six speed transmission.  Magnaflow cat-back exhaust made it sound as good as it looked and ran.  Spent a lot on rubber, even without spinning the rear tires, which are the drive wheels on any respectable auto.

    One of the minor reasons for parting with this beauty was that the starboard head was making weird noises.  I had driven it from new to 70k miles, so no real surprise, just a bit worrisome.  My mechanic, who knows all things Ford SVT (Special Vehicle Team), said it would cost about $3k just to buy a new head, and the labor would be another couple of $k.  So I sacrificed it on the altar for the F350 Super Duty.  I’m trying to segue from gear head to happy camper.  For a guy who used to scream around dirt ovals down south, and who used to build and maintain Chinook helicopters, that’s a task.

    I didn’t know radial engines came in odd numbered cylinder rows.

    The Pratt & Whitney R-4360 Wasp Major radial engine had four rows of seven cylinders each, with each row offset in angle from the previous so that cooling air would not be obstructed by the cylinders of the rows before.  Its displacement was 71.5 litres and the standard model with a mechanical supercharger produced 2600 kW (3500 horsepower), and a variant with two turbochargers in addition delivered 3200 kW (4300 hp).

    Here is one in operation.

    It was used on the Boeing 377 Stratocruiser airliner and the B-36 bomber among other aircraft.

  7. What advantage does a rotary engine give over others, besides being very cool? Is it primarily a smoothness of operation? Smooth power without a hitch? More momentum with less waste of energy?

    This is an aircraft engine. For weight purposes it is air cooled and radial engine is a good way to configure things.

    A rotary engine is in a car and has less moving parts. This video explains things.
