I have a hope that I might be able to squeeze a similar layout in the back of the buggy (possibly post SVA so no hurry ) but space is at a
premium.
<blackadder> I have a cunning plan </blackadder>
Will get the tape on it tonight, but basically the engine crank centreline is vertically above the driveshaft centreline in my installation, so the
measurement is of the order of 300mm max.
Only problem is the chains will be very short, and therefore not very long lived.

Thanks.
Noooo, that would mean it will probably fit 
I didn't realise you'd be running the chain vertically. Nice lateral thinking. Does that not push the engine higher than ideal (from a CoG
point of view)? Not that is sounds like you have the room to do it any other way. Is there no way of cooling the chains to increase their life?

Chain isn't vertical, you have to remember that the output of a bike engine/box isn't inline with the crank!
The output sprocket is nearly the rearmost part of the engine, and the chain travels down and forwards to the driven sprocket.
If you draw a line between the driver and driven sprockets it goes at approx 45 degrees down and forwards.
Yes, it does raise the engines somewhat, but yep, there's no choice really, and at 58kg each all up (and most of that very low down) I can live
with it!!

Got it. Putting the weight back a little like that should help traction on starts as well, as it's getting towards rear-engined.
For some reason the engines look huge, but I think it's because the car is tiny and scale is hard to assess.

yea, that's what I was getting at when I said about the car's wheelbase, its only 6 feet long in total!!
The two engine/gearboxes take up less space than my one vauxhall XE 16v did, and weigh less too!
They are a bargain as well. You can pick up the previous mille engines (the ones without the magnesium bits and with the twin plug cylinder heads)
which are still 135hp, for £300 now in perfect condition. I paid £500 each for mine factory R ones which are '04 4000 mile jobbies

To put another perspective on it, the two chains are 460mm apart, and that's allowing 100mm between the engines!
