[DML] Re: Stage 3 Engine!

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

Access is a relative term. Once the car is set up and running
correctly there is little need to get to those areas. Every 2 years
you do need to flush the clutch but unless you  are putting on a lot
of miles you won't have to tune up the motor for a long time. The
coolant is good for 5 years, the ignition system 10 years (with
limited mileage). I agree that supercharging does have some advantages
over turbos but each has it's own problems too. Some motors will
respond better to forced induction at low RPM's than high and that is
where the supercharger is going to help a lot. The supercharger will
have a fall-off in performance at the higher RPM's, that is where the
turbocharger will work better. Of course it is not only the way you
force induction that matters. The intake, exhaust, valves, camshaft,
all have a major effect on the way a motor will develop horespower and
torque. BTW superchargers have their own problems with heat since they
are always compressing the air/fuel charge the charge is generally
hotter so you must intercool or detune the motor to prevent
detonation. I would not recommend dumping the K-Jetronic just because
you can improve access to areas you seldom need to go.
