hook the turbocharger up to that, and give it some real ponies lol

[slicktrx]

it is already supercharged dude

It wasn't until the the Merlin was cleared for 75" that the Merlin powered Mustangs were faster than the Allison powered versions below 5000ft. The Brits corked up the pop-off valve early on for TacRecon and nothing was quicker than it on the deck till the Griffon Spit. That's why you still see pictures of Recon A models after D-Day.  The Allison was more than 300lbs lighter than the Merlin, could run leaner and smoother, it would always start, and could take more abuse than the Merlin.

Nice Allison, wish I had one

[peteacher52]

I've often wondered why the Merlin was said to be so superior at altitude over the Allison. My gut feeling is, that had Allison engineers been given the "high performance above 25000ft" brief, they could have produced the goods. Maybe it was simply a time factor; the Merlins were there, on the spot, ready to go. I'm not talking about the politics of the deal, just the engineering facts as I see them. I was unawa re of the maintenance and weight advantages of the Allison V12; interesting!Top vid!

The announcer is describing a plane taking off, I believe. The Allison motors are not priced at anything close to a million, but they aren't exactly worthless either.

Wow, if that doesn't give you a woody, you might need to visit your doctor.

@rpurdey

the Allison Mustang was a good low altitude performer, especially with later Allison variants it was able to exceed 400mph, some concepts of the Allison mustangs where equipped with 4 20MM cannons, which i really don't consider much of a advantage beacuse cannons aren't very reliable buy themselves, but it probably packed a real heavy.... punch!

@rpurdey

very true, the Allison was more durable and lighter than the Merlin. and had outstanding low altitude performance, however lacked in high altitude performance! the whole reason the mustang powered by the Packard merlin was faster than the Allison powered one, was beacuse the Merlin could continue to perform at high altitudes, with 1,490hp at takeoff 1,590hp at high blower at high altitudes 1,695hp Military power, and 1,720hp W.E.P Boost!

sounds nice and civilised for such short headers

[HOMeSKILiT24]

That chick with the glasses was probably like yeh whatever an engine so what. Then she crapped her pants. LOL, shes right of the engine

@minedronebiznis

The first prototype Griffon ran in 1939.

[david1513]

a million dollars my ass before id spend that kind of money on a worthless engine id buy a turbine engine, much cheeper and more RPM's, all gas engine sound great with out mufflers, thanks for posting, nice old engine,

[spikonaleash]

@kevrs2  HELL YEA!!!!!!!!!!!!
