altering gear ratio on mk6 fwd for higher gearing-any pitfal

[nitroman]

got the 220 bhp as you know, been talking to a nice chap who says he can alter the final ratio/gear so that all the gears are taller? my object is to achieve a more useable gearbox with all this power and to once and for all show any sphincter van or simalar just wots what.looking for 130mph, so if all ratios are increased by the same rate can any one see any potential problems with whats planned?
ps tryes are v rated etc and suspensions just been stiffened and lowered.

before you say owt!

The only probl as such I can see is you will be sacrificing a little acceleration, but with 220bhp even that shouldnt be a problem.

[motorwise]

what sort of torque figure are you getting?

[AndyG]

If it pulls away in 2nd without a problem (and I guess it does ) GO FOR IT

Your speedo will need recalibrating

i am not shure what ratio diff you have , but i thourt the lowest they do was 4.23 some 125ps had 4.53 i think not shure but i went for the 4.23 this gives me good all round performance but the 4.53 was the towing diff fords said anyway!
but top speed is still 110mph(on the gps) at 4k but it wont go faster than that!

[nitroman]

not sure wat diff n but 110mph is flat out, torque with nitros was 440nm!!!

[madmark]

seems strange that it dont go no faster than mine on the top end!

[nitroman]

it wont do cos its on its rev limiter!!!!!

[AndyG]

but i thourt the lowest they do was 4.23

Who's "they"

Any decent engineering firm will know what would fit surely ( maybe something from a Mondeo )

And top speed will be the same if the ratios are the same mark It's just that nitroman's will get there alot quicker

And when the new diff is fitted, top speed will be alot higher

nitroman, what mad speed do you want your VAN to go

hi andy, apparantly the mondeo box is completely different and is in no way interchangable( ford engineers) the only hope was to custom make the final drive to do this....as for top speed well im hoping for 130+ mph the power is there, the vans 200 kg lighter and its lowered so it should sail through the air better? could this be the worlds fastest deisel van???

All the gear NO idea Not suprised there's no proper auto How mad
What a r e they playing at
