The CD scared me today coming home from the tournament. I had a full
throttle from about 5mph till I merged into 65mph traffic, then a cruise
of about 5 miles at or above 65mph in 3rd gear. Then suddenly the engine
stuttered/burped. For a second I thought I hit something in the road, or
something broke in the suspension. Looked into the rearview mirror and
saw a fairly sizeable black cloud floating away from me. Ahhhhh, 1 less
portion of carbon in my engine!

Ran it hard on the interstate to and from the tourney. 7 or 8 full
throttle starts, 5 up hill. Never let it get out of 3rd gear, keeping
the
rpms around 4000-4500 and higher. Last fullthrottle start was up the
steepest hill within 10 miles of me, reached 80mph/5000rmp1 before the
top. In several of the starts, I saw black smoke right before the shift
points, hadn't seen that before, only whitish smoke. This is a good
sign. At idle, the white smoke is non existant, and barely visible at
3000+ rpm. Not perfect, but progress is being made.
Engine speed alone is NOT effective. What's required is high (4000+)
engine speed with the engine fully loaded. So if the engine won't go
faster at some speed below the no load maximum (which is usually ~5100
rpm) or if the speed is increasing with the pedal to the floor (meaning
the engine is pulling as hard as it can under full load) then maximum
heat is being generated. This is a condition that will consume the most
carbon, fastest!
