Actually, I've sought mileage for a long time too, but
it took a back seat to performance. I have been a major
player in the V6 Mustang modifying arena -see SIX OFFENDER
in the February issue of Muscle Mustangs and Fast Fords-
but now I am hotly in pursuit of maximum efficiency and
approaching it with greater T.E. in mind. If we could get
gas engines up near diesel eff. levels then power would be
easy to come by. I have a couple of engine ideas I'm working
on, one is the "Optimized Otto Cycle" engine http://www.eng-tips.com/viewthread.cfm?qid=141129&page=1
and another is a top-secret exhaust heat reclaimer that
could boost any diesel or gas emgine's efficiency quite
substantially, to the point where one could conceivably
start retaining coolant losses using higher thermostat
settings and channeling most waste heat to the exhaust
system and through the reclaimer for yet higher gains.
Still in the planning stages. Perhaps FORD will buy it
and save the company
I will pursue a patent on this if testing shows a good
increase in T.E.
Back to the car-du-jour, '89 Tracer, the prior owners
claimed 38 MPG (best I presume) and I have gotten 42.8
once and backed it up with a 42.6 and several tanks over
40 MPG. So far I have used clean plugs, timing advance,
new tires (+1 sizing) 40 PSI (Diamond Larry, is 55 PSI safe???)
and acetone. The acetone on very similar runs (70 MPH avg)
showed a 25% gain on a tank, only change made except I
was driving on a much rougher and hilly, curvy road for
the higher MPG run. I'd like to compare it on the same road
and I will get the chance soon.
I hope to use many more tactics like fixing my fuel leak
and maybe some aero add-ons but I need good info on what
works for aerodynamic improvements. I can probably make
most anything, I have good fab skills and resources.
Glad to be here and hope for great MPG for all!
