How much difference does 2" make? (Choosing engine mounting location...)

[RobertoX]

to give yourself a rough idea as to what the change will be you can estimate it using the vehicle weight, current centre of gravity, wheelbase, and the engine weight.

Me = mass of engine (and all ancillaries, gearbox etc that will move with it)
Mv = total mass of car including engine
d = distance to move the engine as a percentage of the wheelbase
%orig = longitudinal location of CoG of the original car
%new = new location of CoG

%new = (Me*d + Mv*%orig)/Mv

with the location of the CoG being the fraction of the wheelbase rearward of the front wheels (in the case you have put up there 48%).

so say your engine and everything weighs 200kg (nfi??) and the car weighs 1500kg and the current distribution is (52/48), say a wheelbase of 2m (NFIx2) and you move the engine back 50mm (=2.5% of wheelbase 0.05/2) then the distribution will change to 48.33% (ie 51.7/48.3)

The big question is, what will this do to the handling of your car

This doesn't take into account the added weight of the heavier engine installed unless you know the weight distribution with the new engine. It does give you an idea though, of the effect of moving a mass of that size back that amount.

In case anybody cares, this is why
