There was a Speed12 engine sat on the floor last time I was at TVR Power... dunno who it belonged to but much better use could be being made of it ...
This maybe the 'lost' engine that was sat around in a crate (I believe it may have been a bit broken, V8Griff mentioned seeing a Speed 12 engine that left 'a nasty oil stain' on the floor when he was at Bristol Avenue once). SAGRIFF said:
