writes Dave Eadsforth wrote in message news:o+F5SWAHQUGAFwMy ... Good day, good people, I wondered if anyone out there (in all probability, Peter!) could help me understand more fully the process by which the Merlin engine was enabled to use 150 octane fuel; one feature of which was the addition of the Xylidine anti-knock compound. (This was touched on in a thread last year, I recall.) SNIP of incredibly useful amount of historical data. Thanks very much for taking the time to type in all that information - very much appreciated. Re. your pondering about whether the Griffon engine was boosted over 25 in. Years ago, I was invited to take a look inside a Shackleton, and while in the cockpit I noted that the boost gauges went up to something phenomenal - I cannot now remember what the numbers were, but they were definitely well in excess of 25. I did take a photo of the interior and I will now try to look it out and see if the numbers are readable. Someone out there who knows more about Shacks might be able to give an accurate figure. Thanks again, Dave -- Dave Eadsforth |

The thanks really belong to the chap who spent a long time trawling through the PRO for the info in the first place. Re. your pondering about whether the Griffon engine was boosted over 25 in.

I did take a photo of the interior and I will now try to look it out and see if the numbers are readable. I'm mainly interested in the Griffon 65, and wether any other models of Griffon were fitted to the Spitfire XIV during the war, but any info on Griffons with 150 octane fuel is very helpful. |
