Very long ago Mustang Monthly ran an article about bolting on 85hp. By
the
time they finished they had replaced just about everything you could and
still leave the engine in the car and still gained only about 50 of their
target 85hp. The remainder 35 or so was from machine work to the heads
and
intakes. This tells me that there is at least that much more power to be
had from the stock engine parts if your just willing to expend the effort.
Of the parts they did replace the two biggest gains were from changing the
intake and exhaust.
That said all this hype about bolting on power by replacing so called
poorly
designed factory pieces with superduper aftermarket parts is just that,
hype! For normal driving the factory parts work just fine, most all of
what
these performance parts do is move the power band higher into the RPM
range
away from what your transmission and rear end were configured for.
Optimizing what the factory gave you, however, just gives you more power
where the factory wanted it start with.
Honestly, my 88GT has 290,000 miles on a mostly stock un-rebuilt engine.
At
75mph the engine is turning less than 2000rpm. What that tells me is with
that big slow turning V8 you need to be thinking in terms of torque not
horsepower, which brings up another article I read about a manifold
shootout, bottom line the manifold that produced the most torque at the
lowest RPM was (drum roll please) the stock manifold. Of the few things
that I have replaced they were intended to help me optimize what I already
had. An adjustable fuel pressure regulator so I could peak the fuel
mixture, a Cobra fuel injector kit, (24lb injectors to replace the failing
stock 19lb ones, 73mm MAF and a new CPU). Unfortunately for those of us
who
like to tinker, as far as the engine is concerned, the factory did a very
good job of getting it right the first time.
Now if you want to talk about handling....
