BluBear Posted September 7, 2011 Posted September 7, 2011 (edited) This was posted on the Keypublishing Forum from the leading Spitfire historian Peter Arnold today: Spitfire XII EN224 - An announcementThe owners of Mk XII Spitfire EN224 have asked me to announce the rebuild contract for this historic aircraft has been given to Air Leasing Limited and upon completion will be flown from Bentwaters. The registration is being re-activated today. I am very excited at the prospect of seeing this early griffon Spitfire up where she belongs! And I can think of at least one other Dog who will be salivating uncontrollably with this news... Also, for those who are unaware who Air Leasing are: http://www.airleasing.co.uk/ Richard Grace wanting a new toy to follow in his late father's footsteps? Excellent. :thumbsu: Edited September 7, 2011 by BluBear Air Leasing heads up Quote

PapaBear Posted September 9, 2011 Posted September 9, 2011 What does the term short block mean ? is it to do with the stroke or the actual length of the block its self. Quote
2. Administrators Jabo Posted September 10, 2011 2. Administrators Posted September 10, 2011 You'll get Painless started again... Quote
BluBear Posted September 10, 2011 Author Posted September 10, 2011 Fen will know this better, but I believe it's to do with the supercharger. The later griffons had two stage where as the early ones had single stage, thus making the length of the engine block shorter. Quote
2. Administrators Jabo Posted September 10, 2011 2. Administrators Posted September 10, 2011 The two stage supercharger was introduced on the Griffon 61 - usually indicated by a 5 bladed prop The version in the MkXII should be either a IIB or VI variant - single stage supercharger - 4 bladed prop From 'Jane's Fighting Aircraft of WW2' - not Wiki - lol Jabo Quote
1. DDz Quorum DD_Fenrir Posted September 10, 2011 1. DDz Quorum Posted September 10, 2011 Whoot! And thats my final statement on the matter. As for short block Griffon, indeed, exactly the same difference as between the Merlin in the Mk V vs. the Mk IX, so it is with the Griffons of the XII and XIV - the two stage supercharger and more to the point the necessary intercooler all add to the powerplants length.
