Fitted a Derv G/Box to my 180

Well as my diff has been whining for a while i thought it was time to do something about it, I was told by a m8 that some 180 owners have fitted diesel boxes so i thought i would give it a try, I think it will improve fuel consumption because at 50mph its only at 1800rpm and at 90mph its on 3200rpm 110mph is 4000rpm

wider ratio will mean you'll lose a lot of performance surely?

is that in 5th. my 180 is a just under 4k at 90. as above, how does it go?

yeh thats in 5th m8 it has lost virtually no performance because of the tourque first gear is not as long now thats the only difference i have noticed plus i still have the sound

as i am doing 140 miles a day in it thought i would give it a try

The ratios are quite different after 1st & 2nd.Should be about the same off the mark,but will then lose some performance
(gear ratios rounded off by calculator)

Basically for the same power & revs 3rd onwards will really slow the car down.look at the rev drops between gears to see & the top speed of the gear what I mean.
if ya look at fourth you'll hit top speed in it.
