150 octane fuel

[Midway]

I understand this was available during WWII on a limited basis in late war.  My wish is that we can choose this fuel by using perks for 150 octane fuel loadout on those aeroplanes where it was an option during combat.

Where's my "eating popcorn" smiley when I need it/

Though I suppose board's been cleansed of the worst offenders on this one.

[Noir]

Ok if you reset everyone's perks.

But I'd be concerned that the MA would be even more all allied than before

[Karnak]

While I would personally find a 380mph on the deck Mosquito amusing, I don't think this would be good for the game.

Also, as I understand it AH does not have the capability to modify the base flight model in the hangar, so for 150 octane to be added we would need a second Spitfire Mk XIV, Spitfire Mk XVI, P-51D, Tempest Mk V, P-47M and Mosquito Mk VI in the list.

The one exception to my disagreement is the aircraft I would like to see redone with 150 octane, the already perked Spitfire Mk XIV.  If it were running on 150 octane it would truly be worthy of being perked.

Here are the official summaries on the 150 octaine fuel with the USAAF and RAF.

Into Service with the Royal Air Force
Following successful testing, the Spitfire IX's Merlin 66 was cleared in March 1944 to use +25 lbs, obtainable with 150 grade fuel. 29   In early May, No. 1 and No. 165 Squadrons comprising the Predannack Wing, were the first to convert their Spitfires to +25 lbs boost and employ 150 grade fuel on operations. Air Defense Great Britain (A.D.G.B.) shared a report, dated 16th June 1944 with A.E.A.F. summarizing the RAF's experience with using 150 Grade Fuel in Merlin 66 engines. All pilots reported most favorably on the value of the high boost pressures obtainable with 150 Grade Fuel, however, Technical Staff felt that before the fuel was introduced on a large scale that the causes of backfires must be established and that at least 12 engines should complete 200 hours each. 30   Eventually the backfire problem was sorted out, see: Backfire trouble resulting from use of 150 grade fuel. 27 July, 1944 and Backfire trouble resulting from use of 150 grade fuel. 12 August, 1944 31, 32

The increased performance obtained with 150 Grade Fuel was put to good use by Mustangs, Tempests and Spitfires in intercepting Buzz Bombs launched against Britain beginning mid June. Performance increases at sea level were as follows: 


  ------------------------------130 Grade---- 150 Grade 
Spitfire IX --------------------335 mph----- 358 mph   +25 lb 
Spitfire XIV ------------------359 mph------ 366 mph   +21 lb 
Tempest V -------------------372 mph------ 386 mph   +11 lb 
Mustang III (V-1650-3) -----360 mph------ 390 mph   +25 lb

Maybe then the Mustang would cruise at the speed it is listed as being instead of being nerfed.

I see lots of 109 and 190 drivers still flying their planes. And not just the K4 or the D9. They like those planes and know them VERY well.

Nope, give it to us so I can stop flying with a handicap.

[Bruv119]

I'm with midway on this one, 

Spits need to be able to catch all those runners!!   Give the 150 octane and lets hear the 

[Krupinski]

Only if I us luft dweebs get a K4 with C3 fuel. 

[Tank-Ace]

If you get that, I want the MW 50 boost and C3 fuel for all aplicable planes. Even then, Japan gets screwed over, Russia gets screwed over, Italy gets screwed over, etc. Besides, we need a 150-octane fuel like we need Hitech to sell Aces High.

Unperk the spit 14 and then theres no real reason to completely screw up all of the perk prices, ENY levels, restrictions, etc.


Really, this just sounds like a way to make the P-51 live up to its runstang legacy, and to give the spitfire almost de jure noob/skilless-pilot-ride status.

This document shows that 150 was OK'd as a standard for these aircraft by 8\44 for both airforces. Only 4 JG of 35 in the west flying G10\K4 were OK'd for 1.98 ata with C3 by 3\45 per a single document at Kurfurst.org. Fw190's were the primary single engine users of C3. Bf109 for the most part used B4. Before 3\45 the Luft basicly had ceased to exist and our over use of the K4 in the game is more like a what if 1946 scenario.

If anyone bothered to read WW2 history, yes the US beat the Germans and the Japanese because the US kept improving it's technology and output volumes to beat their enemies while blowing the snot out of them with hoards of hot aircraft. And the P51D and P51B\C were both OKed to run on 150 by 8\44 as a standard. With Merlin 66 spits, P51D, spit14 and TempestV on 150, maybe adjusting perk assingments and values would need their occasional review by HTC. Then the LWMA furballs might get more intersting because the K4 would not be able to hang everyone up beneith it with it's WEP. It would simply be one of several unperked WEP monster late war rides available in the LWMA instead of "the" unperked monster WEP ride. I really couldn't see the P51D using 150 perked more than 8-10 or even that.


From Spitfire Performance Spit XIV vs 109G\K
http://www.spitfireperformance.com/spit14v109.html

The Spitfire XIV was the most marvellous aeroplane at that time and I consider it to have been the best operational fighter of them all as it could out-climb virtually anything. The earlier Merlin-Spitifre may have had a slight edge when it came to turning performance but the Mark XIV was certainly better in this respect than the opposition we were faced with. The only thing it couldn't do was keep up with the FW 190D in a dive. It could be a bit tricky on take off if one opened the throttle too quickly as you just couldn't hold it staight because the torque was so great from the enormous power developed from the Griffon engine. One big advantage that we had over the Germans was that we ran our aircraft on advanced fuels which gave us more power. The 150 octane fuel that we used was strange looking stuff as it was bright green and had an awful smell - it had to be heavily leaded to cope with the extra compression of the engine.

The 150 octane report document now shines some light on the statement by this spitXIV pilot.

If you get 150 octane fuel, I want my C3!!@! 

[Tank-Ace]

Still  no reason to give 150 octane fuel to the US/UK aircraft. Really, I can just see it completely screwing things up for quite a while.

My mustang isnt fast enough!!
My spit outturns everything but i want it to outrun everything too!!

Sometimes it just cant be good enough.
Oh and wi ahr teh Luftwheeneez, right?
