Old designs with modern engines

[Scotaidh]

Some - OK, a lot - of us have already done this kind of thing - engine swaps.  It seems to be one of my favourite whifs - Whirlwind with DB601s instead of Peregrines; Brewster Buffalo with a Corsair engine; P-38 with DB601s; Cutlass with J79s; with more planned and parts accumulated. 

How well would some of those first & 2nd gen fighters have done with modern engines?  A Vampire with a Spey?  Airacobra with F404s? 

So that's my idea - take a - your favourite? -  early fighter design and alter it to accept an engine it (or you) could only dream of it having. 

Mods, would this make a good GB?  (or has it been done?  I've never done a GB, so I don't know)

It was done a couple of years ago

Nothing to stop it being proposed again of course after the 2 year subject rest period.

A Vampire with a Spey would have nearly three times the thrust, would need MUCH bigger intakes and exhaust, and would probably rip it's wings off. 

It tells you something about the speed of jet engine development that the 1940s vintage Goblin 3 engine in a Vampire put out 3,350lb thrust and weighed 1,550lb, while a late-model 1950s Viper put out about the same thrust and weighed around 600lb...

You could put TWO Viper 12s in a Vampire engine bay, have 5,400lb thrust and it'd STILL be about 400lb lighter while having around 400lb more thrust than any Venom.

Or, you could put a Klimov VK-1 in a DH2...
(Any excuse to post my favourite build of the last few years.)

Never mind fighters, if you want SERIOUS over-powering airliners are where it's at. 



The 'Re-engine It' GB was one of the best we've had in recent times I thought.
