Hi all
Now that my GMC is running fine again - I needed some
kind of "benchmark" testing to establish a base line
for my coaches performance. I wanted a means to
evaluate future enhancements and a means of checking
my coach periodically.
Now my solution my not be very el agent - but I belive
it will work for me - and in fact if others will
participate - perhaps we can build a database of
performance timings to more accurately gage which
modifications produce the desired performance
improvements.
METHOD
STANDING START - pedal to the floor - record times for
zero - to 30 / 40 / 50 / 60 / 70 miles per hour
CONDITIONS
Coach Type ---- '73XPD - 26'
Engine/ yr ---- '73/455
heads ---- "j"
ignition ---- "HEI" (springfield)
initial ---- 10 degrees
advance ---- ported vacuum
Gas ---- 87 octane (true gasoline)
load
gas tnk ---- full
propane ---- 90% full
waste ---- empty
water ---- full
cargo ---- 150lbs tools/supplies ?
A/C ---- off
Engine comp---- 170 psi (approx - all cylinders)
road ---- level
air temp ---- 70 degrees (love Florida weather)
vacuum ----
idle ---- 20" (neutral 850 rpms approx)
50mph ---- 16"
60mph ---- 14"
70mph ---- 12"
RESULTS
0-30 ---- 7 seconds
0-40 ---- 11 seconds
0-50 ---- 18 seconds
0-60 ---- 27 seconds
0-70 ---- 40 seconds
Any one else willing to post there results ?????
