BBK's 70-millimeter throttle body I have here today is a good option for any of my '94,
'95 5-liter owners out there that are looking to squeeze every last bit of power out of
their naturally aspirated or force induction motor.
And when it comes time to install this, expect a very easy one outta three wrenches in our
difficulty meter here, about an hour job, all you need are basic hand tools.
We're gonna show you how coming up soon.
So when it comes to moving air into and out of your 5.0, there are a few general rules
here, guys, cold airs, throttle bodies, and intake manifolds coming in, and you got long
tubes and a cat-back moving it out, but some parts have a tendency to move air more effectively,
like long tubes compared to a pair of mufflers.
Now if you've done both, and you also have some air or exhaust mods, then you're literally
looking at where your power bottleneck is, and it's usually the stock restrictive throttle
body.
Now while throttle bodies aren't mods that make gobs of power on their own, when paired
with the aforementioned modifications, they really will add more power that can't be found
elsewhere, and in the long run, we're all hunting for bigger numbers, right?
So the Mustang's factory throttle body comes in at around 56 millimeters, and BBK's here
is gonna be a 70 millimeter.
Now, while the bigger diameter sounds like a small upgrade, it's actually a big step
in the right direction, but bigger doesn't necessarily mean better on its own here.
If your motor's completely stock, this is not gonna do much for you, but if you're investing
in exhaust pieces or an air intake, maybe an intake manifold or even other power outers
[SP], that OEM throttle body will quickly become a bottleneck.
Now this throttle body fixes that, it's gonna free up that extra air to your motor needs
to take advantage of those other mods.
Now lookin' at the construction a little bit for you, this throttle body is made from a
permanent mold casting of 356-grade aluminum to produce a higher quality casting than a
conventional sand mold which reduces porosity for an improved finish.
And while we are on the finish, this does have a pretty nice looking polished look that
is gonna fit well under any hood.
Now it's worth pointing out a couple things here, guys, one ,this is not a tune required
part, meaning that you can simply install it and hit the ground running, not have to
pick up a Ford back [SP] Aluminator [SP] chip, but we're always gonna recommend doing it.
Now two, this is more of a recommendation from me and everybody else here at American
Muscle, and like I said a little bit earlier, if you're gonna do the throttle body here,
it's really best to pair this at least with a cold air intake to really yield those gains.
With that being said, BBK's 70-millimeter throttle body by itself costs only around
220 bucks, which will make this about 70 bucks more than the SR Performance offering, and
your main differences here are merely going to be the manufacturing process and the brand
name.
Now this throttle body is precision CNC machine while the SR Performance is cast, which is
generally a little bit less expensive to produce.
And when it comes time to the installation, just like I had said a little bit earlier,
guys, expect a very easy one outta three wrenches on our difficulty meter here, and about an
hour job only needing basic hand tools like a socket set.
You're gonna wanna start by removing the negative battery terminal, followed by the hose from
the throttle body to the air intake, then detach the three cables to the throttle linkage,
followed by unplugging the throttle body sensor, as well as the idle air control sensor.
Now at that point, you can then remove the 4 nuts holding the factory throttle body onto
the intake manifold with a 13 millimeter wrench or socket.
Now you can then remove the factory IAC and throttle position sensor.
And once they're off, it's gonna be a great idea to clean the IAC with a little bit of
car cleaner before you throw it back on.
Now you'll then install the throttle position sensor and IAC onto the newer throttle body.
So with the supplied gasket, you'll install the new throttle body onto the intake manifold
and secure it with the factory nuts, and torque 'em down a spec.
And once you're done there, you'll then reattach the linkages to the throttle body and plugs
onto the TPS and idle air control.
So once you're done there, you can then install the hose back onto the new throttle body,
then connect your negative battery terminal.
And once you're done there, you're gonna wanna fire your car up and then adjust the idle
by turning the Idle screw.
Now if that doesn't change the idle, just adjust the throttle position sensor until
you're where you need to be.
So that's gonna wrap up my quick review and breakdown of BBK's 70-millimeter throttle
body, fitting the 1994, 1995 5-liter Mustang, that can be found right here at americanmuscle.com.
