Thanks Luke. I will defo try it I think, but first and foremost I'II get it up and running and repainted. Its just that if I have spare boxes about its probably worth toying with them over the months! No harm done and I'd like to known whats inside it!
I wish I could do a whole ratio range swap, I've heard about 1st gear being redundant with the 24V in the Transit, in fact its almost redundant with a 5.14 diff and 75ps engine and a 2 tonne tipper unladen as it is. I can dream about a 4.11 but realistically, I'II be using the 4.63 twin wheels for the most part.
I've done my sums and in Fifth Gear with my 4.63 diff and the Transit box I make it a (Theoretical ) 40mph @ 2000rpm! ?!? This really should be 55mph minimum shouldn't it?
Transit (0.82) 5th Gear:
2000rpm x 60mins/hr x 0.0012769miles per rev / 4.63 x 0.82 = 153.228/3.7966 = 40mph
6000rpm x 60mins/hr x 0.0012769miles per rev / 4.63 x 0.82 = 459.684/3.7966 = 121.1mph
Modded Scorpio (0.76) 5th Gear:
2000rpm x 60mins/hr x 0.0012769 miles per rev / 4.63 x 0.76 = 153.228/3.5188 = 43.5mph
6000rpm x 60mins/hr x 0.0012769 miles per rev / 4.63 x 0.76 = 459.684/3.5188 = 139.2mphSeems a waste to have a four speed box though? I now know the 2.5 litre TDCi Scorpio box which forms the hybrid with the sierra V6 bellhousing for the 24V is ratio'ed at 3,61 2,08 1,36 1,00 0,76.
1st at 3.61 being the same in the 16V 2.0 DOHC Version too. Which means that 1st (3.61) is a lower ratio than the Transit's 3.89 so it should go a little bit further on the same revs no?
Do you know if its possible to swap all the gears out of the MT75? ....and...what is your top speed, 0-60 times and kerb weight with your cossy?
I'd like to drag this one day but I'II stick with the Ford America theme, ie. looks good (To my taste) and has moderate horses, but is inherently unstable with a terrible build quality and bits missing and probably breaks down before it makes the show!
Almost ready to go ahead but I'II keep dreaming for the mo till the bank balance is slightly healthier.
I don't know if these endless calculations are right, but from 40mph - 121mph in one gear!
Talk about motivation!! It would be nice to iron out some of the basic pitfalls in my mind so I can just focus on the mods needed for handling..like probably repositioning the engine inside the cab, see how I go first
My Mk5 was biodegradable and disintegrated with time.
