Has anyone done this? I have made a tool to turn those big dials, but not sure if its CW or CCW!

They should both be normal r/h thread [so counter clockwise to remove] I haven't actually done a BTR from a TVR but have done a few BTR,s from the Aussie V8 commodore,s which are just a slightly bigger series of diff and they are definitely r/h thread.

My 'puny' 229hp seemed to do fine with mine ... 90mph at 3,000rpm and still saw 164 on the GPS (with admittedly very little more to give).

I have a higher ratio one to drop into mine as I bought a spare dif as mine has a bit of slack in it but not really sure what to do - probably have time to get mine rebuilt before mine's back on the road again!

I`m not enjoying the 3.45, I had the GKN diff which seemed better.

What ratio do you have ?

Given that I'm doing 3,000rpm at a (GPS indicated) 90 then I'm *PRESUMING* that mine's a 3.08:1 ... I bought Alex's old diff (so that I could swap it over without taking mine off the road) which is almost certainly the higher ratio version.

That would be the GKN 3.31
