Mark,
you still don´t think simple! If your gearbox breaks, it´s too weak and you have to change it anyway. Thus the suggested way of testing torque is cost neutral!!![
)].
I don´t know the spec of the T50 box, which is obviously in the CRS (I couldn´t find the spec in the net). The T5 transmission is o.k. for 270 lbs/ft (the first owner of my car found out that the engine torque exceeds 270 lbs/ft). The reinforced version (which had the honour to be tested by "Il Ingegnere" itself, who found out that the torque of the engine exceeds 330 lbs/ft) is specified to 330 lbs/ft! If the T50 spec is the same as the T5 spec, take care of the swarf!!!
As for cost neutral solutions, here the solution for your fuel tank:
The solution looks very british, but in fact it is the result of a dutch-italian cooperation. The advantage of these fuel cells is a low movement of the fuel during acceleration and cornering!!!
