The way to overcome the lack of a central diff, is supercharging both engines.

 

If the front end looses traction, as the engine speeds up, its supercharger feeds more air to the rear engine which consequently produces more power.

 

And vice-versa.

What, so the charger on the front feeds the back engine and the charger on the back feeds the front? Surely not.. that would be some long old pipework back and forth

Doesn't have to be 'long' pipework.

 

You could have 'long' V belts from one engine to the other.

Just reading this thread out of interest, as i have little knowledge of rear or twin engined minis. Does lead me to a question though, what's the reason to do it?

 

I'm thinking the obvious of centre of mass is better and some folks prefer rear or even all wheel drive (if two engines)

but

Its obviously a lot of work, is it worth the extra work to have a little more grip/handling etc

 

I'm not getting at anyone or anything asking these questions, just curious

 

For me it was the challenge to make it work as a daily drive.  One gearstick and two engines all the time.  It has been on the road for about 10 years. Have done hillclimb and motorkhana, primarily to prove it all works under a bit of pressure.  It is the same as driving an ordinay mini, but more power and noise.  Now doing a bit refurb / repaint and improvements like the cooling.

Good on you, I've always liked doing things, just to see if they can be done. This takes that to the next level. 10yrs use is a good innings for a 'special' build as well. Makes my City E rebuild look like a walk in the park (it has NOT been a walk in the park)
