    I have an old VHS tape of that race circa 1990 or so. Nick Mason and David Gilmore teamed up with Alain DeCadenet and some other guy for It. They wrapped one of the copies around a tree. Great video set to Floyd music, of course.

    Tank version of the Merlin, no supercharger. Rover made them under contract during WWII.

    The Meteor tank engine is very similar to the Merlin. Both made by Rolls Royce, the same specialized tooling works for both. An acquaintance of mine works on Merlin's and he has a meteor tooling kit for them. The accessories, supercharger, exhaust and intake systems are different however.

    The strangest thing about the Merlin and Meteor is that the valve seats in the cylinder heads are screwed into the head, not pressed like every motor I have worked on. As you might imagine they are put in with lots of torque. The valve seats have a central part for turning them in (very coarse thread) and then they machine the central part out as part of the rebuild, making the valve seat as it is removed.

    The valves have 1/2" stems, and the exhaust valves have sodium in them for convection cooling as many piston aircraft engines did during WWII.

    The Merlin's biggest challenge was keeping the tetra-ethyl lead in suspension (anti knock) in the very long intake track. Spark plugs were always a challenge (fouling with lead). With the two speed two stage superchargers wartime maximum power setting was 61 or so inches of mercury. The Reno racers run very exotic fuels (not gasoline), cooling by boiling over and over 90 inches of mercury as the race power setting. The charge cooling system (inter cooler) is eliminated because of to much restriction and the charge cooled by evaporation of the ADI fluid (methanol and water). Often the ratio of the supercharger speed system is altered as well.

    There was a real possibility that this could have been a real Merlin beater, had politics not got in the way, The original ford big-block.

    The original idea was a 1650 cid V12 aero engine, aluminum block and heads, true DOHC with cams operating directly over bucket lifters. The V12 never really got off the ground, but was developed into a V8 of 1100 cid, for use in tanks during WWII. It was rated at 525 HP @ 2800 rpm, and had 1000+ ft/lb of torque from 1000 rpm throughout its operating range.

    Pretty impressive stuff, IMHO.

    Just put a fresh LDS465 in my M109A3 that I'm turning into a motorhome. It's the 5-ton version of the stockmultifuel engine. Little more power. But the best part is that it will burn anything, and Racor designed a fuel processing/filtration setup that will allow me to pour just about anything straight into the fuel tanks.

    Have 100 gallons on the truck and will have at least another 100 in the trailer. Averaged about 10-11mpg with the old 2.5-ton multifuel engine, which isn't too bad considering how big and heavy these things are. But it's really not about the MPG, it's about the Miles Per Dollar.
