Valver boxes have different ratios and arnt as strong.

The willy box has a longer 5th gear and is strengthened.

ratios are the same including 5th... i've not noticed any difference, me and Northy change gear at exactly the same time and had exactly the same top end... bout 145 on the clocks

5th is 100% different. I personally think 3rd and 4th are slightyl longer but could be wrong. Williams box is stronger as gear teeth are chunkier according to those in the know (Nick Hill, transmission specialists)

could do a valver Vs willy box shootout :lol:

the only speeds I can remember is 2nd is 55mph ish, 3rd not sure, 4th will go to just over 110mph on the clocks and 5th is 145mph exactly on my clocks... :?

On my valver box i get.

1st = 40

2nd=62/63

3rd=90

4th=110

5th=130 but not on the limiter yet. All other gears are to the limiter

dude thats with a valver limiter so means nothing. Williams only revs to 6400rpm.

Hang on a mo. I have the complete ratio set-up here somewhere. And if memory serves me correct, all the gears are different apart from 1st.

Way to compare would be what speeds you are achieving at 5,000 rpm in each gear.
From what i can remember i get 20mph/1,000rpm from a 16v box and about 21.6mph/1,000rpm from a willy box.
