Plug heat range
What determines the chosen plug heat range? When my engine was dyno'd it had a 1050 dominator ona victor junior manifold. the dyno controller said that it wasn't doing me any favours but, as it was all I had, he dyno'd it. It made 600 HP and 600 ft lbs. He also advised that i put a colder plug in, which I did.
I have now fitted an adapter and gone to a 850 double pumper. I have only lost 2/10 ET but 6 mph. Is this fuelling? I expected to be slower but not 6mph. Also how do I determine if its still the correct plug? |
