engine location
I'm currently designing my chassis, and the way things are panning out, I could use some space between the front pulleys and the line of the
front axle.
Am I right in saying that I reall yneeed to get the engine as far back as possible anyway?
Or is it possible to go too far back with it?

In the perfect world, mid engined is the way to go, but things aren't perfect.
Whatever position it is will have advantages/dis-advantages. You will learn to drive within these confines.
Take a look at dpcars and have a look at his racer.
The bike engine is in the passenger position.
It all depends on what you want from your car. If you want to carry passengers, then this set up will not suit you.
As long as your engine is somewhere between the axles and not outside of them, it will aid the handling.
That is why lots of cars now have a wheel on each corner.

OK, cool - so as long as I keep it all within the two axles, I'm not far wrong

Yeah, but back is better.
The engine/box and you will account for nearly all the mass that you have control over where it goes.
If you imagine your wheelbase the same as it is, but have the engine 30 feet ahead of the front axle (ignore the fact it'll fall over for the
moment), it will take an eternity to turn. Put it a few feet in front of the midpoint and steering will be much quicker. More mass also take at
back.
I'm sure someone will be along to tell you otherwise

No, that sounds fine. I knew that one of my objectives was to get the engine back from where it currently is. Pulleys just behind the front axle was
the target, but becuase of "packaging" it needs to come back about another 8 inches. As far back, in fact, as it go.
I was worried whether the moving back could go too far, but then thinking about it, mid engined is WAY back!
So I'm happy...
