3.73 rear axle????

[ryzman]

what do you reckon if i fitted a 3.73 axle to my van... found one and will be able to make it fit!!! BUT do you think it will over gear it and just labour the engine with a load in the van?

i don't mind dropping to forth gear occasionally but don't want to be spanking the clutch and chasing the gears all the time!!!

i would of thought with your power increase allready it will help a lot.

as youve allready got more power to weight than standard it shouldn't kill your acceleration.

i've just bought a 6 speed mondeo box for my van i can't wait to see the difference, and if it kills my accceleration, i'll just have to get the power up to match.

check this web site you can put ya details in to check speed... i put mine in and at 4500 van should do like 120mph

Mine works transits got this ratio, just the a standard 115ps TDCi, I suppose it helps with the 6 speed box as the ratios are closer matched, I think its doing around 2300rpm at 70 in 6th. The other transits at work are mostly 140ps and they've got a factory towing pack and a lower diff set up, acceleration is quicker (more power and lower gearing) but you pay for it on the motorway with a busy engine.

thats good info there Lostpaul,

the 0-62 times conclude that the first few gears are the same ratio, do you think

interesting i thought that the 5th gear ratio in my box was 0.82? is there another 5 sped box with a differant ratio then?

[jolly olly]

Can anyone post up the the details of a mk 6 90 ps (lwb semi if it makes any difference) cheers.

[Daveyboy]

Has the mk7 115ps the same ratio six speed box as the 140ps?

looks like it applys to the 90 aswell

EDIT sorry KW=84.6

[lostpaul67]

thats good info there Lostpaul,

the 0-62 times conclude that the first few gears are the same ratio, do you think

The 0-62 times conclude that the 125/130/140ps fwd is a lot quicker on accelleration

[winterheating]

what about some info on the FWD's MK6

and possibly mondeo tdci 130 6 speed?
