Genklemens,

I just bought a 32mm punto 60 throttle body and was about to bolt it to 1108cc Sporting when I remembered a post I read a long time ago about removing material from the TB and mounting block to improve oomph. I have trawled the darned forum and can't find it - How much can I take out of the (30mm i/d) mounting block (I have a lathe) and what needs to come out of the TB? Pete, I know you recessed bolt heads and did lots of other stuff - what really works?

Thanks
