i've got an xc falcon that i have recently fit a ford T5 (from an ED XR8) behind a 351C. Obviously the speedo gear needed changing, so i went and visited the local ford dealership, told them my situation also noting that i have a 2.92 diff ratio. They sold me a pink gear drive (19 teeth) and my speedo reads 110kmh when i'm actually travelling 100kmh. If anyone can accuratley tell me whether i need a brown (20 teeth) or a green (21 teeth) speedo gear it would be much appreciated!!!
The T5 in the XR6T is a higher spec version than the one you have, and I have replaced a number of them after 2000km with 270rwkw. The EDXR8 box was never good for that output, but you will help it live by running a lower diff, ie about 3.45.
If you're not driving a manual you're really just steering.
How did you manage to wreck the gearboxes? I've heard of one guy who stripped the input shaft of an XR8 box with a monster Clevo, but never heard of any problems otherwise! My mechanic ensures me that the gearbox could handle up to 300kw without any dramas, regardless of the diff ratio, and he is a vastly knowledgeble mechanic.
