hi, i have the placement of the parts, and what parts to use and not use and i have a diagram, i just need to lay it out in the car now, so, which layout would work best, any ideas?

Here is the diagram which shows that the car will have a high speed and power ratio to the current weight and torque of the car and the diagram also shows that it can switch between 4 and 2 wheel drive:

i think i have the shaft connecting and the other parts lay worked out like this:

(this is different to the above link because that one shows the layout for the horsepower transfer, this one is just the same transfer but he actual real model layout of the parts.

I have been reading your posts with some amusement, you seem to have all of the components but never in the right order.

Front and rear engines may give a 50/50 weight distribution, but the weight is in a worse location than it would be if it was centred within the car. I'm trying to think where it has been used as the optimal solution rather than a design exercise or out of necessity due to the underlying chassis not being designed for 4x4 or a single big engine.

To add a central differential and gearbox to a Front/Rear engined combo removes any advantages such a layout would have, introducing more weight and packaging issues. You would need to have double the number of driveshafts of a more conventional 4x4 system.

Your last diagram shows the gearbox doing nothing. The engine to the left would have no gears, only a clutch. Why is there a direct connection between the front and rear diffs, bypassing the central differential? Maybe I'm reading it entirely wrong, but I don't think text diagrams are the way to plan such things out.

i don't see anything wrong with it

the center diff acts as a transfer case which connects the two shafts, the gearbox is the power source you can just switch between 4 wheel and 2 wheel drive (the downwards arrows indicate that the center diff connects to the shaft)

In your diagram, the central diff connects to the front of the right hand engine, not the gearbox.

The left hand engine does not connect to a gearbox at all.

the gearbox connects to the rear engine.

he center diff connects the two shafts

the top diagram is NOT a parts layout its a horsepower transmission diagram the center diff still gets powered by the gearbox

the center diff has two output shafts

one we send to the front of the car

the other to the back

the input shaft or two input shafts is for the center diff so it can link the two shafts.

at the front of the car the center diff output shaft is the input shaft for the front diff

the other output shaft of the center diff is the input shaft for the rear diff

one clutch is in-between the two engines and the other is in-between the gearbox and rear engine (the other side of the engine not the end where the other clutch is)]

both flat 8 engines are mid mounted

Must just be me being daft then - I've never seen a transmission diagram where the components haven't been in order, to me that would seem illogical but you clearly know what you're doing.

Can't wait to see it built.
