Why don't you PM Mark at Abbeymotorsport and ask if you can observe some stuff in their dyno room, the chances of anyone lending a car are almost zero I would say, purely from an insurance point of view alone.
**EDIT** What happened to your car?

A good deal of your posts have involved "to borrow" and I'm posting this so other members are aware. You may have very honest intentions but as one or two have already adopted a cynical or "inquisitive stance" on this thread it seems fair to make people aware.
