Diesel M66 gear ratios

[p fandango]

Don't forget P2s have a larger circumference wheel/tyre combination so the speed would be lower in an 850 on a standard set up.

all my gearbox speeds are done using 225/50/16 (my tyre size lol)

Exactly, Robs theoretical speed would probably need something like P2R wheels to work (235/40/18)

My new box is the m56L2/4:25, ill.let you know what I think in a couple of weeks

1st-4th are the same as your old M56L but 5th is higher (0.70:1 on the L, 0.65:1 on the L2

this is how the speeds@6500rpm compares to a normal T-5 M56H. M56H on the left, M56L2 on the right

1st = 39 33
2nd = 68 59
3rd = 101 95
4th = 138 130
5th = 172 174

Yep read the pdf before.I bought it but to be honest I didn'thave a.lot of choice at cp motors, plenty of t5 /4:00 boxes lying around common as muck

i still reckon your going the wrong way lol

We've agreed to disagree on this one, well at least till BT hits the strip so I'm safe for a.couple of years yet

thats some long gearing, mine will only do 64mph@2000rpm in 5th

edit = just done a quick calculation. If you the longest 6th available which is 0.54:1, with the lowest FDR available which is 3.77:1 you can get 73mph@2000rpm

I`d be happy with that

Yeah but you'd need to cog it down 2 gears to overtake anything lol

No, coz I`d be in the outside lane overtaking everthing

I think you are laughing all the way to the strip with your first 4 gears james

It`s ok playing at home with FD`s and ratios if you have time and patience to get it right, but don`t forget it has all been done before!

Remember when the 5th gear box first came out on production motors........4th gear was the fastest and 5th just a slow overdrive!

Max. torque at the right revs/mph is the key......

This is roughly the gear ratios on the auto 2k = 70mph

Does anybody know if diesel m66 fit a petrol? And what about ratios and approximate mph in each gear.

Also is the angle gear the same on diesel boxes, I'm thinking of converting a t6 to manual

it'll bolt straight on the same, but no idea about the angle gear. Not sure if you'll have to get a M66 with matching FDR to the rear axle

Came across this over on VS

Just found an m66d awd box cheap, but don't think final drive will work for what I want.

It's the e51 box 197mph

Can you chuck pic back up pretty please
