like TC says it ends up being +15% which dircectly translates to ET and
MPH however the quicker and faster you go the less you notice it. I
would run a 12.2 at 112mph and the next weekend at sea level with
absolutely no adjustment to the carbeuretor run an 11.2 at 121mph. My
vmax was doing second gear roll on wheelies at sea level. Something that
is unheard of here in colo w/o major tricking the clutch.
Now regarding my HP. My bike was rated at sea level at 191HP. I dynoed
it here and it came in at 171 corrected for sea level however the actual
hp was 143HP. So that is what I am really working with. The 171
corrected is still a mystery to me. My friend has a 1427 long rod that
dynoed at sea level 171HP. When he got it here and dynoed it he showed
169HP. The delta in hp is almost nil. So there is a discrepency that is
pretty massive. However When I ran his bike at the track i ran 126MPH on
his bike. When I ran my bike at the track I ran 129.7MPH. SO I am
showing quite a bit more HP than him at the track. That is probably 10
HP difference. The remaining 10 HP is probably being lost due to my Hi
compression engine being a point off of what it was supposed to be 13.6
at sea level. It probably is only 12.6. anyway that should give you an
idea of some of the loss that colorado gives you..
Take care Phil
