Here is data for almost all Polo gearboxes, with a help of a gear/speed calculator (that is easy to find online) you can check what is the impact on speed.
172mph.... wow!not that this is relevant or helpful, but the other day i was driving a new bmw 120d and at 70mph the revs sit at 1850rpm... lol thought it was interesting haha
I will be popping an 8p 5th into my atv box. Make the A road driving a tad more easy going. Where would I best source such a gear?I'll second that question - I fancy trying the 8p 5th too, just hope there's not too much of a gap from 4th, at least you can change 5th gear with the gearbox fitted if you don't like it.
Ay lad, you had a mosey at the state of my diff! Need to sort that before I refit the box
