Finally a Corsair back in the Air Race circuit.
-
Sea Furys seem to dominate nowadays.
Do they use Centaurus or R-2800 in those Sea Furys?

Ah, a little Googling and it appears that at least the "September Fury " has a R-3350.

The one that caught my attention was the FM2 "Air Biscuit". Now how do you suppose he will do against Strega, Rare Bear, or the other big hitters.

All of the Furies Sea Furies use r 3350's except for Dreadnought, she uses the mighty r4360 corn cob motor
Very few have there original engines as they dont hold up to hot roding and parts can be a cast iron -itch to find
-
The results are all listed at the link I posted.
The FM-2 was running the 6 laps at a 280MPH clip.
The fastest heat the F2G ran was 370MPH.
I believe the Sea Fury's are running mostly Bristol Centarus, Dreadnought is running a R-4360 like the F2G and September Fury the Winner this year which is a work of art is running a fuel injected R-3350-93. The same race team also runs "Big Bossman" the F7F racing at Reno.

None of the Furies at Reno use the Centarus, all are equiped with Wright R-3350 engines. to the best of my knowledge there are only 3 Centarus powered Furies in the USA (Sanders Bros dads Furie being restored) Elswoerth Getchal (Spelling?) currently flying with Centarus, one other with the Centarus dont know of flying status, another 4360 Furie is Furias- currently for sale
an easy way to tell whitch engine is on board is if it has 4 bladed prop its a R-3350, 5 Blades Bristol Centarus, Plus the Centarus turns backwards from R-3350

One of my neighbors has a Sea Furry. It's a super awesome ride. We he does a flyby, you know it! :cool:

I was at the races. The Super Corsair had a lot of problems--didn't complete a lap in either of the Saturday or Sunday races. I was disappointed I didn't get to see him tear it up.
Big Bossman is a sight (and sound) to see. It is without a doubt the most beautiful aircraft in the circuit. I don't know what it is about twin R-2800's, but it sounds more mean than any of the hot rodded planes. Dang thing is basically stock and still ran competitively in the silver unlimited. It'd be awesome to see what it would be capable of if it was modified with all the drag reduction that could be done. But, then it would ruin the otherwise pristine and most choice aircraft that it is.
Just about all the Ponies blew up. I saw one merlin engine with a hole blown through the bottom of the case you could stick your foot in. Threw a rod or something. I guess that's what happens at 100+ manifold pressure...Rare Bear also blew a piston. Lots of metal in the engine--its trashed. They auctioned off the piston. Looked like somebody hit it on the edge with a sledge hammer.
I've got some pictures coming to me--I'll see if I can't post 'em.

How did they fix the lateral instability that plagued the F2G? Or the overheating?

iirc Dago Red was running over 130" :O :O :O :O :O :O :O the year it won at over 500 MPH (2003 i think)
-

I believe the lateral instability was the increase in size of the rudder. the overheating was a chnage in the design of the airscoop on the front of the cowl.

I've seen numbers as high as an estimated 120" on the merlins. I'm sure they go higher since no one gives away trade secrets. I think the radials are starting to take their toll on the Merlins. Dago went through 2 engines last weekend. Didn't make the final. Pretty incredible when you think wartime power was capped around 70".
Hey F4UDOA, was the bubble canopy stock on the F2G?

Doesn't work for me, can someone host it?
-

Yes, the F2G only had the bubble canopy in production. Goodyear actually put the bubble on the FG-1(F4U-1) as well although it never went into production on that airplane.

This seems to be Rare Bears continuous fate. If it doen't blow up, it wins. It seems that in this case, it blew up in qualifying and never raced. This year's winning speed (September Fury, 482 mph) was well below what Rare Bear can do. Both Rare Bear and Dago Red have averaged better than 500 mph in past unlimited finals.
My regards,

Apparently Dago Red's owner wasn't going to race it this year. Another guy actually leased it for the race. $150,000 per engine (that's what I was told anyway) times two=$300,000 in blown engines and didn't even make the final. Must be nice to have that kind of money to throw around. Apparently Jack Rouch of NASCAR fame has his engine shop manufacturing Merlin engine parts for the P-51 racers. It hasn't turned out very well as there was a guy (P-51 team crew member) there wearing a t-shirt that said "Rouch doesn't know Jack about Merlin engines..."
-
it was probably not too bad a bet, given that plane's history as the fastest ever at Reno and how big the prize money is
-
So is the NXT Nemesis going to finally challenge the warbirds? I've heard they can easily double the horsepower they had on tap (stock IO-540) to win the Gold Race this year, averaging 360 mph. If so, that should put it in the mid 400's easily. A super-modded Nemesis could concievably exceed 500 mph.

Mmmm, yummy.

Nemesis finished 3rd in the sport Gold. I don't think you're going to see him in the unlimiteds. They were talking about dropping a custom built IO-720 in it next year, turning roughly 800 HP. That should be interesting.

Just FYI Nemesis took 1st place.
Quote from the press release:
"With only a stock Lycoming TIO540-NXT, Sharp took first place in the Gold Championship air race at Reno this year with a speed of 360 mph."
That's with about 300-400 horsepower. Doubling the horsepower should give at least 25% increase in speed. Which as I said puts it in the mid 400's, hanging right there with the warbirds.
-
Well, you're right. I was there and thought Parker took 1st, with Von Grote in second after his penalty. I guess the beer was taking affect. Parker was actually blowing both of them away until his engine laid down on him.
Unless they add some weight to Nemesis, he won't fly unlimited. There's a 4500 lb minimum weight restriction.
-
Doh, forgot about the minimum weight thing. Is it even possible for Nemesis to fly at that weight?
-
the web site for the kit you posted says max gross is 2600, but that would go up with a more powerful engine, probably it would need stronger gear. doesn't say what Vne is
-
Lycoming O-720 weighs in approximately 120 pounds heavier than the 540. I didn't realize the Nemesis engine was stock. I know Van Groten's plane turns around 600 HP from its IO-540. Nemesis was in a solid third place before Parker's engine quit, and Van Groten cut the pylon. But, if he hot rods a IO-540, changes the aspiration, or puts in the 8 cylinder, he'll probably be much more competitive. Possibly even blow them away. I did see a reference to a "Super Sport" class for next year, but can't verify that. Maybe that's where the 8 cylinders are going. He revolutionized the formula 1 series with the original Nemesis, so I imagine that down the road, we'll see him get up front.
