If link won't hilite just punch it in

the clay Lacy entry which took sixth....a Le Mans style line up on two parallel runways, all fired at same time, releasing in pairs...DC-7 couldn't be in line up though because he would have blown some of competition OFF RUNWAY, so the ungainly entrant also started with a bad handicap. Lacy AVERAGED 325 mph and the winning F8F Grumman Bearcat Averaged 344mph....pretty stunning and totally off the hook....never say never. They prepped a 1049 Super Connie to "friendly" compete for 71, but sanctioners banned the big birds from ever running again...kinda like Bill France banning Aero Cars from nascar....no balls, no heart. Now if a Guy can take an airliner & give challenge to unlimited warbirds.....then i can take this
View attachment 264252and Drift/Autocross it.....stay tuned, because next year the pipe dream will become a reality.
Some interesting factoid...right now, the low altitude unlimited speed record holder is a F-51 named VooDoo flown by Hinton of Chino's Planes of Fame,,His Son actually.....the record is 472mph

now in 1934 for the Schneider Trohy low altitude amphibian races, this italian Macchi Mc.72 w/ counter rotating two blades did 444mph!!

now....take the MAJOR DRAG of those pontoons off and...You figure it out....life can be surprising, so before You laugh Your *** off at me because i want to counterlock an RV.....refer to the above.
And i mantain my opinion that a P-51 on ground looks better with inner gear doors open, such as VooDoo above
Airgrabber is absolutely correct about hydraulic bleed down...i have seen. birds with mods that keep system under pressure...something similar to Accusumps...a device made for Vee Wee's back in 70's, to pressurize oil galleys prior to start up.
Typo on the Lacy rundown above...winner was not an F8F, but a Hawker Sea Fury...i always get them mixed up because they are similiar in size & look....couple of Baddass Sea Fury's out @ CNO (Chino) notoriously loud on low hi speed passes....The Grumman is Pratt R-2800 and the Hawker is A Bristol . DC-7's & Connies were the CW 3350's.......not many people realized that the DC-7C & last variant of Connies. the 1649 Starliner, were both over 400 mph airliners at altitude.....the Howard 500 also uses the same variant R-2800 as Douglas DC-7 (pretty sure DC-6 as well) & Convair 280's. @ stage blowers...the Howard was built to cruise @ 41,000, tho grumman played the feds into restricting it to 25K w/ Pax & 35K for cargo, just pencil pushing horseshit...my point is a recip that breathes in turbine territory. Any way, winner of 1970 California 1000 @ Mojave was a Hawker Sea Fury @ 344 avg speed. Still think the Macchi with conventional fixed gear would match VooDoo's 472mph record.. The Macchi did 440 in 34....32 mph isn't much difference to 81 years of tech advance...know what i mean Vern?
