how fast 100ps td with 4.63 diff?

[gassed transit]

anyone know how fast the 190 semi high roof lwb 100ps td will go with a 4.63 diff? (ita a 1999 T reg) . ive seen one locally for sale and want to change my 70mph (75 down hill) S reg 190 semi high lwb if performance gain is worth it.
cheers, Baz.
ps, present van has the 5.14 diff but i doubt it would go much faster regardless of which diff i fitted!.

Seem to think they used to do about 90 on the flat

In theory flat out is 91mph with a 4.63 (unless its a luton/high top) I would think the 100PS should have enough poke to get pretty close!

BTW max theorectical for a 5.14 diff is 82, I have hit that (according to sat nav) in my N reg 190 with the 5.14 diff

You missed a bit out Matt

Nope... A27

But who is to say the GPS system I have is accurate??

So what's the theoretical top speed of a SWB 100td 85ps with a 4.56 diff?

if you are still useing the epic pump, put the 100ps injectors in (you will love that) 33710

on a 4.11 or the rare 3.90 diff.

cheers for the info, think i will try the td. just sold my vivaro 03 reg and that really shifted (chipped approx 125bhp) so 90mph top end of turbo transit should mean a reasonably steady cruise 75/80 without killing it or my eardrums i hope.
my mate suggested i go for some different rear tyres (235/80/15) off a 4x4 as he reckons they will raise the gearing slightly there by reducing revs, anyone know if this is correct?.

There's nothing in the service printout to say the pump has been changed? it's an ex company van so unlikely any upgrades have been made.

[MinorMatt]

gassed... its very unlikely those tyres would fit in the arches without rubbing!

no probs, already high on backend anyway for loading bikes. would probably look like a dragster wannaby with bigger tyres on back.
