| Features:
17" 2 piece wheels, 37"Goodyear ATS, T400 4l80e Automatic with a stronger
output shaft
Engine modifications:
P7100 mechanical pump, 4" exhaust, Torque-pro propane charged, Mallory
lift pump. Scheid Hi-flo injectors.
Notes:
The Hummer's final drive ratio is steep, so a VP44 electronic injection
pump would mean a rather slow highway pace. The P7100 pump can be run
several hundred rpm higher with a set of governor springs, which lets
the Hummer scoot right along with the traffic. The other advantage to
the P7100 would be that for military use the mechanical pump would probably
be more durable and reliable in adverse conditions. |
