Griffon 58

Properly fitting bits, then.

Nice motor will it fit in the landrover!

We got the v8 baby brother in a series 1….. only 18 litre

None, it’s connected to a gm400

What transfer box is it using ? Dana 20?

None, straight to a custom built strange engineering 9” back axle

No, it’s not a spelling mistake, it is griffon- specifically a rolls Royce griffon 58 out of a Shackleton bomber. I meant to post this the other week but forgot…..

Since the untimely demise of the merlin (which incidentally is currently in bits and prepped for rebuild) we borrowed an engine for the next show in the season. As I’m terrible at photos, you get what you get here, but it was a vintage fly-in at breighton aerodrome near selby.

The engine in question is this old girl, swinging 9 foot contra rotators and producing one hell of a prop wash. Being used to the merlin with a test club on and half asleep, this key piece of information escaped me on the first run of the day, and I lost my ear defenders, my glasses and very nearly my shirt down the runway!

And here’s yours truly being awarded the broken con rod from the merlin…..

The engine behind me is an Alvis Leonides- ex sea prince. Basically the same as the engine I’m building for myself and my dad, ours is a provost engine. Oddly enough, mine has the prop this engine should have, a dehavilland hydromatic, and this one is wearing a rotol provost prop

Do you still have the water meth injection system on it?

Do you still have the water meth injection system on it?

Yes but not operating. Truth be told it’s scary enough being sat 2 foot behind it at 1800hp, 2500hp max is horrific

We stripped this Shack down and managed to get it out of the building through some large double doors. Those Griffon props are huuuuuumungous. Had to strip them apart to fit through the door and then go onto a trailer

The gearbox assembly to rotate the 2 props in different directions is a piece of clever engineering. One shaft inside another.

Sorry for the thread hijack, Dan.

Got any more Griffon porn shots?

Hi Rob,

Is that the AVRO 707 in the background?

Nice to see a power egg! I have a video of us cycling the pitch on the prop if I can work out how to upload it! I believe we are back down at Santa pod in October with it again

Avro 707. Now at Old Sarum, along with P1A Lightning prototype.

We never did work out how to get the aft prop assembly off of the Griffon. Nobody would lend us the manuals and I've a suspicion you need some very expensive spanners for the job.

Should have asked, I bet Peter has them
