What!!! The Merlin had only a design capacity of 3-400hp. Unbelievable, truly. How ever did Rolls-Royce ever get over 1500hp from the Merlin 45M and 55M engines?

This is Priceless! :grin::grin::grin::-P:-P

Name the 16 squadrons you claim were the only ones using 100 Octane fuel on operational trials - with documentary evidence please.

Explain how 16 squadrons managed to chew through 52,000 tons, that's 16,405,633 gallons of 100 Octane fuel while on operational trials - with documentary evidence please. In fact, considering that the "trials" started in February, explain how 16 squadrons chewed through about 74,000 tons, 23,346,748 gallons of 100 Octane fuel February - September 1940, with documentary evidence please.

Explain the logistical arrangements the RAF made to supply only 16 squadrons with 100 octane fuel, with documentary evidence please.

Prove that the Merlin was rated at 400hp with documentary evidence, thank you.

NZtyphoon, add 65 squadron at Manston during August (when they were not at Hornchurch).

Post 372 demonstates that all the Hurricane units with the AASF and Air Component in France required 100 octane fuel and that 100 octane was held at the Aerodromes and depots.

Combat reports show that 11 Group Reinforcements in France also used 100 octane fuel.

From: Brian Cull, Bruce Lander and Heinrich Weiss, Twelve Days in May, (Grub Street, London, 1999), p. 309

"On 17 May the following Hurricane units were represented in France: 1, 3, 17, 32, 56, 73, 79, 85, 87, 111, 145, 151, 213, 229, 242, 245, 253, 501, 504, 601, 607, and 615 Squadrons."

Various Combat Reports from Hurricane units in France during May 1940 noting boost cut out used, +12 lbs, etc. signifying use of 100 octane fuel:

1 Squadron, 11 May 1940, F/O Paul Richey
3 Squadron, 14 May 1940, Sgt. R. C. Wilkinson
17 Squadron, 18 May 1940, F/O C. F. G. Adye
17 Squadron, 19 May 1940, F/O C. F. G. Adye
56 Squadron, 18 May 1940, P/O F. B. Sutton,
73 Squadron, 14 May 1940, F/O E. J. Kain
79 Squadron, 14 May 1940, P/O D. W. A. Stones
79 Squadron, 20 May 1940, Sgt. L.H.B. Pearce
85 Squadron, 10 May 1940, S/L J.O.W. Oliver,
87 Squadron, 15 May 1940, P/O R. P. Beamont
87 Squadron, 18 May 1940, F/Lt I. R. Gleed
87 Squadron, 19 May 1940, F/Lt I. R. Gleed
151 Sqquadron, 18 May 1940, S/L E. M. Donaldson
151 Squadron, 18 May 1940, P/O John Bushell
229 Squadron, 28 May 1940, Sgt. J. C. Harrison
229 Squadron, 29 May 1940, P/O C. M. Simpson
245 Squadron, 28 May 1940, P/O K. B. McGlashan

Lane, it doesn't matter how many squadrons are shown using 12lb boost, 100 octane fuel, the fact is there was only 16 squadrons that did so and that was in testing, there was never enough 100 octane fuel and the Merlin would blow itself to smithereens if more than 4.5lb of boost was used. :rolleyes:

Hey, I'm confident that Crumpp will trumpp everyone with extensive documentation, proving beyond doubt that the RAF kept all of its 100 Octane fuel in strategic reserve while only allowing 16 squadrons to use maybe 74,000 tons to cover intensive operational trials - in which only some squadrons would use the fuel full time - in order to convince the RAF that the fuel worked in Merlin engines rated for 400hp. Its gonna happen. Have faith. :cool:

So much for the 1/3 power.

Can somebody give me some cliff notes on this and what's wrong with which planes atm? I hear a lot of tips for the 109 vs spit suggesting the 109 dive away/use superior speed. So was the 109 faster, if the spit was supposed to have 12lb boost and 100 octane fuel? How should the 109 fight the spit if the spit was in fact faster, climbed better and outturned it?

Was the G50 really as bad as it is ingame? How is it that it has a higher HP:KG ratio by some margin than the Hurricane yet the latter is practically the equal of the Spit/109 ingame?

All around confused here.

Spitfire Mk I Pilots Operating Notes, dated June 1940:

http://img862.imageshack.us/img862/3...kijune1940.jpg

This is an Inspection and Test Certificate for a specific aircraft with a Merlin Mk III engine. Inspection and Test Certificate is probably the same as an FAA Form 337 allowing major modification for research or testing purposes. Note the document clears a single aircraft by serial number on 28 February 1940. The July of 1940 Spitfire Mk II manual clears the Merlin III engine for use of 100 Octane fuel and notes +12lbs may be used.

That is not the Spitfire Mk I but rather the Spitfire Mk II. There is nothing authorizing the Spitfire Mk I to use +12lbs in any of the Operating Notes.

I think there is a typo in this sentence. Not sure if you mean Spitfire I or Merlin XII.

Crumpp Interesting find, can I ask if you can show the page where it mentins the fuel to be used?
If it doesn't then it would be refering to the early war 87 octane as that was the only fuel available. The date of the Pilots Notes is not a definitive statement as was proved by Kurfursts version of the Mk II pilots notes which had an incorrect date.
Other clues would be the instructions re the prop normally around the mid 20's section and the fitting of armour plate for pilots protection normally around item 40.

Look forward to seeing the above.

PS How are you getting on re the proving of 16 squadrons?
