Firstly it's not a BMW box, they build rear wheel drive cars, the CDTi MGR car is FWD, it is a Getrag gearbox. Well built & well able to take increased torque.
As regards ratios vs speed, couldn't give accurate answers, but as I said previously, in top gear, 1000RPM = 30MPH, therefore 100 MPH = 3300 RPM.
Just go & buy one, you know you want to!
sorry already knew it wasnt a BMW box, just rushed typing it last night.... just ment the box that goes on the BMW lump, as its going to have longer ratios being a powerful DERV, than the little 120 1.8 16V lump.........
but knowing now ive just said that, its most proberly got the same ratios
i know you already answered before, but you did say 100mph = 3000ish rpm.... just wanted it in every gear...
jesus steve, your in the know how, wasnt expecting an answer like that, but i cant thank you enough for the response..... only problem is ive got to work it all out now.....
i totaly understand all the ratios but my biggest problem is the final drive???? ive never quite understood where that figure comes from, and how you use it to work at the gear speeds????
