Engine swap

[C612DNM]

I've been reading the intrepid engine swappers and modifiers discussing their ideas on here, so I'm taking a leaf out of their books.

I have a Mk1 shell in the corner of the yard, and I was thinking about fitting a Pratt & Witney 9 Cylinder Radial in it, but because space is at not at a premium, I reckon I'll have to use a three speed David Brown gearbox driving through the nearside front wheel only.

What's getting me is whether I should use a single 45DCOE, or whether I should use bike carbs. I have a couple of Mikuni's off of an AP50, which should be OK as that was an autolube engine, not a premix.

What do you reckon?

Can have some of what you're on please lol

Pete, no problem. You need to go to Aldi. They sell Disco Biscuits!

I've got it in, but can only get 8 pipes down there at the moment......

ahh bit of hero eh...

wouldnt you think a single carb is not going to be sufficient enough; bottlenecking the induction a bit..?
Hell, if youre going as far as sticking this radial thingy in - go for bike carbs. x4 bodies for air = much better.

Is that x4 bodies per cylinder = 36 bodies for the 9 cylinder radial?
However, I did consider using a chain drive from the prop reduction box, but after consulting a few ideas shown on YouTube, I think that a centrally mounted radial, with a 20.8 x 38 tyre fitted to the outside of the engine, and the crankshaft fixed/welded to the inner wings, thus the cylinders form the spokes of the drive-wheel.

My quandary is this - the best rating I can find for a 20.8 x 38 is 40km/h, and with a tyre of this size rotating at rated speed of 2200rpm, having a rolling radius of 52", that's a circumference of 163", and that means 339.58mph.

I may need something better than the 1.0L discs and drums then.

It should work.

Better than a 1.2 head on a 1.6

here's the engine in question -

So imagine that with the rim bolted to it (that as the centre), and then the crankshaft fixed firmly to the inner wing....

I reckon it's a go-er.

It's 1344 cc, err no, that's C.I. (22L) that'll do.

Are you going to stich weld the engine bay?








lollollol
