yeah not to mention drag racers as well especially those that are running alcohol,
gives me the sense of how adaptable engines can be and how far they can be out of tune if you say move from Christchurch to Cromwell.
I always found my turbo diesel would out run my straight diesel up to the NI skifields and my little chevette with a petrol would do better than them both
