Isn't that a Merlin engine?
Hawker Hurricane?
P-51 Mustang?

Rolls Royce V-1650 Merlin. First flew in a Hawker biplane, most well known for being used in the P-51 mustang.
The early Merlin looked a lot different than that version too... different intake and different cylinder heads. Very interesting development history.

It is a Merlin.
I'll accept the Hurricane as one of the first widespread applications, do you know the other?
Again, yes it is a Merlin, specifically a Packard built Merlin. As far as the Merlin is concerned, the first application you have is a bit off.
There were several versions of the Rolls Royce V-12 engines before it was named the Merlin.
Still looking for what the Merlin... specifically the Merlin I first powered...

Avro Lancaster!

Surprisingly, the Lancaster was powered by the Merlin XX!
This airplane even predated the Hurricane... (Merlin II)

Fairey Battle?... or Hawker Hurricane maybe...
As a side note... if you're an air racer you're looking for a very rare, very specific merlin... what airplane used it and why do you want it?

D'oh! Is it a biplane of some sort? For some reason I'm picturing a biplane on floats, but I can't think of the name of it.

Nice! Although that's a bit of an ugly bird...

from what I've read it flew that way too 
keep in mind that the early/vs. late Merlins had a huge difference in power output, and that aint a small airplane.
anyone want a stab at my extension to the question?

The only thing I can come up with this late is the Merlin 130/131 series.
2070 hp (highest rated Merlin)
Also was redesigned to give it a smaller frontal area.
Used in the de Havilland Hornet and Sea Hornet.

Believe it or not output is not an issue as most of the racing engines use Allison V-1710 connecting rods and specially designed/modified pistons.

Too obscure I suppose
You would be looking for a 620 series merlin, also known as a "Transport Merlin."
They were built in small numbers for the Canadair North star, basically a DC-4 with Merlins instead of radials.
The transport Merlin, unlike the fighter and bomber versions had to run reliably in airline service for hours at a time, day in and day out and thus had a significantly beefed up crankcase, which is very very rare today and highly coveted by those seeking to build a merlin that will withstand 160 inches of manifold pressure and make over 3000 horsepower.

Ah yes!
Obscure, but not that obscure...
I was thinking racing from an aerodynamic standpoint (thus the streamlined 130/131) rather than a mechanical (how much power can we make from this engine) standpoint.

You do have a good point. It's always better to tweak aerodynamics than try to brute force your way around them. I would bet that since transport Merlins are so rare now that aerodynamics plays a much bigger role in the future... if Reno survives that long I guess.

I hope it does survive... it is still on my to do list (along with Oshkosh and Sun N Fun)
The 131 would be very useful if somebody got the bright idea to run the course backwards!
