hi f bird . happy new year and all that
yes it was rich as hell with 72s on the primary side , i still have 78s in the secoundaries for now , but was difficult to get "wot" and see what the air fuel mix was reading from lambda senors as the crank sensor wasnt reading 100% dyno guy shut it off and said to change it as when the secoundaries kick in - if the sensor miss reads a tooth it could fire the wrong plug , so i have ordered a ford vetec sensor which pushes more lots and will compensate fot the engine resonation ( noise and movement combined )
but he had it running very smooth on primary side and idle at 925 ish , started each time fine.
pulley ratio is bottom 45 and top 51 . so -8% under driven given me around 10 lbs boost.
