the exhaust cooler only gives a few seconds that is all.
engine temp is different for every motor do not be to concerned about it tune preformance not temp.
That's exactly what I would have thought about the exhaust cooler; but it would have put us across the line at Bayside on Sunday, and it is cutting it too fine. No mods, JPI exhaust & manifold (don't know which number), O.S.TZ, O.S.P7 plug (perhaps too cold?) No head shims. Perhaps we could still lean the top end a bit more, its not getting too hot.
Would an O.S. tuned pipe, or a hotter plug help you think? We usually run a Jammin Hyper EFRA 2645 exhaust; as it seems to make the engines run faster, but we're having the same fuel economy problems with that exhaust. We're planning to be at Brendale on Sunday, will you be there?
Kindest regards,
