All the ones I have seen, have made about 160-167. This is on Sheps rollers which are regarded to be accurate.
Agreed, Paul is very good and has also turned out to be right in all the advise I have asked him reguarding M20 tuning and has proved so on his rollers!
BTW Jon remember my sport made 160BHP at the last track day? It had a BBTB and that shite Alpina C2.5 chip that is doing the rounds and I said I could feel the loss in power after I fitted the pair. Well I returned it to standard and took it back to Paul and it made 170BHP
Really sweet M20 in that car, even Jonb thought it went really well, definately one of the best I have had over the years.....
