I tuned a car today with a 218 224 114lsa crane cam - that ended up going fairly well - but it is idling at 64Kpa at 800rpm .....and reasonably smoothly!?
The full throttle Kpa drops as low as 95Kpa when Baro was 102Kpa.
Stock airbox
Shaved heads
extractors - exhaust
Is there is a reason for such a high idle Kpa - my car was a smaller cam and heads has 45Kpa?
