Re: power shifting

["Brian Haygood" <scirious@hotmail.com>]

small suggestion:  Speed shifting becomes less jerky when you change the 
order a little bit:

come off accelerator slightly,
clutch in,
shift and accelerate at about the same time
clutch out.

That accounts for the lag in engine response, and helps the revs drop as 
soon as the clutch is pressed in.  Of course if the time between coming off 
the accelerator and tapping the clutch doesn't match your engine's response 
time, then you are likely in 2nd place.  Match those times and you can get 
smoother, faster shifts than otherwise.  Works to smooth out normal shifts 
on the street as well.

Systems like some of MSD's can use a trigger on the clutch pedal to cut the 
spark momentarily, providing a dip in power that matches the cluthc 
movement.  Theoretically the engine's response time to a cut spark is faster 
than to a blipped throttle.  Who knows.

Sincerely;
Brian Haygood
