INLET ADAPTER (1994-95 MUSTANG)<br />
M-9927-A50*<br />
This adapter allows use of GT-40 EFI manifolds on 1994-95 <strong>Mustang</strong>s.<br />
Must be used with the new M-9926-B50 throttle body. Installation of GT-40<br />
EFI manifolds requires minor modification to the hood blanket, and use of<br />
<strong>Ford</strong> <strong>Racing</strong> strut tower brace kit M-20201-A51 (see page 147).<br />
EFI HI-FLOW EGR SPACER<br />
M-9474-A50*<br />
This EGR spacer has been machined to a 67mm<br />
bore diameter to be compatible with the <strong>Ford</strong><br />
<strong>Racing</strong> 65mm throttle body. Can be used with<br />
either production or <strong>Ford</strong> <strong>Racing</strong> EFI manifolds.<br />
Requires minor modification to production upper<br />
intake manifold to achieve optimum results.<br />
EFI THROTTLE BODY-TO-<br />
EGR SPACER GASKET<br />
M-9933-A50* 1986-93 <strong>Mustang</strong><br />
M-9933-B50** 1994-95 <strong>Mustang</strong><br />
This gasket is manufactured with a 67mm bore<br />
diameter to accommodate the <strong>Ford</strong> <strong>Racing</strong> 65mm<br />
throttle body and EGR spacer. Fits between the<br />
throttle body and spacer.<br />
EFI HEAT SPACER<br />
M-9486-A51* Stock 5.0L Manifold - .5"<br />
M-9486-A52* GT-40 Manifold - .5"<br />
M-9486-A53* GT-40 Manifold - 1" thick<br />
for clearance with<br />
M-6582-E302 Valve Covers<br />
New and improved quality, made in the USA. CNC<br />
machined from Westinghouse. Type C phenolic<br />
material fits between the upper and lower<br />
manifolds to help dissipate heat and significantly<br />
increase performance. Includes longer bolts.<br />
GT-40 Stock 5.0L<br />
EFI UPPER-TO-LOWER<br />
INTAKE MANIFOLD GASKET<br />
M-9486-A50*<br />
This gasket is required to assemble the <strong>Ford</strong><br />
<strong>Racing</strong> upper intake manifold (M-9424-A51<br />
or M-9424-D51) to the lower intake manifold<br />
(M-9461-A50 or M-9461-A58).<br />
EGR SPACER-TO-INTAKE<br />
MANIFOLD GASKET<br />
M-9464-A50*<br />
This gasket is manufactured with a larger 70mm<br />
bore diameter to accommodate the <strong>Ford</strong> <strong>Racing</strong><br />
65mm throttle body and EGR spacer. Fits between<br />
EGR spacer and intake manifold. If you have ever<br />
tried to modify the production gasket to fit a larger<br />
spacer, you will truly appreciate these pieces.<br />
Also use with M-9927-A50 adapter.<br />
EFI MUSTANG FUEL PUMP<br />
M-9407-C50* (190 liters/hr.) 1986-97<br />
This high-flow, fuel tank mounted fuel pump<br />
eliminates top-end fuel starvation on modified<br />
5.0L EFI HO engines. Production flow rates of<br />
88 liters/hr. (1988-93, 1994 and up 110 liters/hr.)<br />
will be increased to a whopping 190 liters/hr.<br />
@ 40 psi with M-9407-C50.<br />
ENGINE<br />
COMPONENTS<br />
ELECTRONIC FUEL INJECTION “SPEED DENSITY” VS. “MASS-AIR” COMPARISON<br />
Computerized electronic engine controls and fuel injection make it more<br />
difficult to improve engine performance. More sophisticated approaches<br />
are required—such as <strong>Ford</strong> <strong>Racing</strong>’s “Mass Air Conversion Kit” for<br />
<strong>Mustang</strong> 5.0L HO engines with manual transmission. Here is a brief<br />
review of key factors:<br />
Remembering that engines are basically air pumps, the basic problem<br />
for an EEC-IV computer is to determine airflow for any given throttle angle<br />
and engine RPM, so it can signal appropriate fuel flow to mix with the air.<br />
The 5.0L HO uses two types of fuel control. 1986-87 and 1988<br />
49-State vehicles use a SPEED DENSITY system—in which airflow is<br />
inferred from several sensors, including measurements of engine speed,<br />
manifold pressure and air charge temperature, along with an approximation<br />
of the engine’s pumping characteristics. The 1988 Calif. and all 1989-95<br />
models use a MASS-AIR system—in which airflow is measured directly<br />
with an air meter. A “hot wire” sensing element in the air intake provides<br />
an output voltage reading that is proportional to the mass of air flowing<br />
into the engine.<br />
The mass air system reduces the calculations required to control fuel flow<br />
and ignition spark advance—while providing the versatility required<br />
for performance modifications affecting airflow and manifold vacuum.<br />
It reacts faster and more accurately to changes in airflow, and improves<br />
idle quality and overall vehicle performance.<br />
