1/6 scale Miss Supertest III

yes they had multiple plugs and multiple distributors, some of the plugs are under the intake and some under exhaust manifold.


upper arrow upper spark plug wires, lower arrow spark distro, same on other side





Merlin and Griffon use much of the same block and such intake is just different

the images are "Merlins"

picture from service manual showing intake on the more recent version of the Merlin there is a intercooler between the supercharger and intake. By the way the ignition on the Griffon is on the rear (front in an aircraft) opposite of Merlin.
here is a picture of the Griffon


this photo shows ignition top of output shaft ( have not seen "true Griffon" top of block) I assume Griffon has multiple spark plugs it might have ONLY been added to more recent Merlins.

above is a Griffon setup for a Hydro (same grey Griffon as above) shows gearbox

There is so many variants hard to keep track of all the changes. There are a lot after the MK58.
EDIT
Not sure of this but the Griffon might have died after the MK 58 its the only reverse rotation Merlin that I have found.

no problem I love to research projects, there is so little info on Miss Supertest. Until my research I never knew they lined the bottom of the hull with Magnesium plate, used "wet sponsons", fiberglass cowls, 2 stage superchargers....

EDIT
here is a good source of info wiki on the Griffon

Hi have you bought a Rolls Royce replica engine from Eddie Hansen for your boat? I ask as I have had no reply to my enquiries to purchase a 1/10 scale one for an Atlas Van Lines U71. Perhaps I have the wrong contact details.
Thanks

Maybe you missed earlier post that No one knows whats up with Eddie Hansons dummy motors or drivers.
Jim Williams said he stopped carrying the engines and drivers because he wasnt recieving new orders from Eddie. Oh yeah check it out. Rumrunnerracing.com might be a good place to ask the status of Eddie's engines. Be sure someone on mgb knows theyre just not talking

I got my kit from Doug Campbell at Hydroclassics.com





But I think it looks a wee bit small...might have to build a larger one.
