Suppose the Mosquito was fixed...

So, a Mossie with Merlin 25s and ejector stacks = close to 360 mph on the deck?

So, a Mossie with Merlin 25s and ejector stacks = close to 360 mph on the deck?  

Probably in the 350-353mph range.  That is faster than the P-38s, P-47D-40, Ki-84, Spitfire Mk XVI, Bf109G-2 and so on.

The Mossie in AH does have Merlin 25s so far as I can tell, they are just dampered.  If they were Merlin 23s I don't think it would be breaking 325mph on the deck.   I also don't think the instruments match the engines, I think the instruments may very well be for Merlin 21s or Merlin 23s.

As soon as Karnak posted tha graph, I took a quick look at Mike Williams' pages of the Mossie.

The last test done on the 20th of September, 1943. http://www.wwiiaircraftperformance.org/mosquito/hj679-dh.pdf The second test seems to perfectly agree with Karnak's graph, about 380 - 384 mph at some 12 - 13.5K foot high.

The Merlin 21's on the other hand hit a similar speed but at 21,600 foot, while the SL top speed is somewhere around 320 mph. So let's get those exhaust shrouds off already.

Probably in the 350-353mph range. 

I'd be cool with that as well.

helloooooooooo!

i'm currently onboard the Ark Royal to learn how each of the ship's departments are run.  I will even get to see some harriers at some point, i'll definately make an attempt to get some footage + photos of them.  Unfortunately I have little time to play AH for the time being

Posting from *aboard* Ark Royal?

Now, that's pretty cool, right there.

Best of luck with it all, thrila.

Hey thrila, don't get yourself into too much trouble!

Karnak, I recently bought a small die-cast Mosquito. It's not 100% accurate, but I noticed a couple things about it. It's supposedly an FB.VI, it's got the guns to prove it. But the engine cowlings look different. If you search up Mosquito FB.VI, you get this:

Other Mossies (like my model) have this cowling:


I'm not sure, but it seems like the Canadian produced Mossies have this cowling. I'm assuming only 2-stage supercharged Merlins would need this. Since the oil cooler, cabin heater and rads are in in the inner wings, the intercooler is where the old intake was and the new intake is now that hole under the prop.

In addition some of the Mossies I've seen have only 10 exhaust stubs per engine:

[Karnak]

The engines on the two stage Merlin powered Mossies project further out from the wing.  I believe that is because the engines needed more room to fit the larger superchargers.  You'll see that on the Mk IX, Mk XVI and Mk.30 for example.

As to the ejector stack count, single stage Merlin powered Mossies didn't have room on the inner exhaust ports to fit six stacks due to the position of the radiators.  In some cases you can see such Mossies with five ejectors on each side, the last two cylinders sharing an exhaust port, and in other cases you can find them with six ejector stacks on the outside and five on the inside.  It doesn't seem to matter that much and seems to have been done based on what was available.  Single stage Merlin powered Mossies would be the Mk IV, Mk VI, Mk XIII, Mk.26 and so on.
