Dave from AmericanMuscle, today I have the stack racing 70mm throttle body, designed
to fit the 96-2004 Mustang GTs. This will exclude the Cobra and Bullitt as they have
a different style throttle body. The idea of a throttle body is to continue to give
your car better air flow, going from the intake, to the throttle body, to the plenum, and eventually
into the motor to make more power, because more air equals more power. Now this stack
racing 70mm unit does feature a polished aluminum finish, and easy installation. It look great
when you install this in your factory location. What we’re going to do today is take this
70mm stack racing throttle body, and install it with an airaid cold air intake kit on our
GT. But before we do that, we’re going to get some stock numbers on our base GT to see
what kind of gains you pick up when you pair these two together. We ran our GT on the dyno
with bone stock trim to get some baseline numbers, we came back with 221 horsepower
and 260 ft/lbs of torque. We’re now going to install the stack racing 70mm throttle
body, this can be done at home with simple hand tools, in some cases it may require you
to enlarge the hole for the stock throttle cable, but again, it can all be done at home
with simple hand tools. We’ve now got our Airaid cold air intake and our 70mm stack
racing throttle body installed, we’re going to combine these with a bama performance tune,
the idea is to get the most horsepower and the most throttle response possible, and the
combination of the cold air, throttle body, and tune, should achieve a pretty good gain
in both for us. Let’s run it on the dyno now and see what we pick up. We just ran our
GT on the dyno with the Airaid cold air intake kit and the 70mm stack racing throttle body
combined with a 93 octane bama performance tune, we resulted with 247 horsepower, and
291 ft/lbs of torque, that’s a gain over stock of 35 horsepower and 43 ft/lbs throughout
the curve.
