Regardless
of which tuner, air
filter, exhaust system or aftermarket
intake you may already have, you need to dramatically increase
your air flow. No other aftermarket intake comes close. Bottom line
is CFM + does not make tuners, air filters or exhaust systems. But
what they do is engineer, design and manufacture the ultimate intake
for the Cummins and Powerstroke diesels. |
| Why
is the CFM+ the ultimate intake manifold? |
|
Even without a computer it’s easy to see why
the CFM+ flows so much better than the angular stock aluminum manifold
with its nearly 40% flow restriction at the front mounting bolts.
(Fig. 1)
|
 |
| But
why does the CFM+ flow so much more air than the other oversized cast
aluminum manifolds in the market and maintain lower air temps? |
 |
| There
are a number of reasons we will discuss:
1.) The very
large center section of the competitor cast aluminum manifold may
look impressive but it is very bad for flow. The inlet to the manifold
from the inter cooler and the outlet of the intake manifold into
the engine are very similar in cross-sectional area so when the
center section is over three times larger than the inlet and outlet
the air flow slows dramatically through this center section. The
air flow then is forced to speed up to exit. This causes turbulence
in the flow, leading to pressure drop or pumping losses.
2.) The competitor’s
manifold is so oversized in the center section that two of the mounting
fasteners which hold the intake to the engine had to be changed
to long bolts or studs that must pass directly through the air flow.(Fig.2)
This causes tremendous turbulence in the flow leading to additional
pressure drop or pumping losses.
3.) You can
also see in the picture of the cross-section of the competitor aluminum
manifold there are two surfaces (Fig.2) protruding down into the
flow path that create recesses into the outside surface of the manifold.
These pockets allow the mounting nuts to look good recessed on the
outside but cause a big problem on the inside where it matters.
(Fig.2) These two surfaces protruding into the air flow act to trip
up or tumble the air flow. Again this causes additional turbulence
in the flow leading to pressure drop or pumping losses.
4.) Cast aluminum
has a much rougher surface than the advanced technology composite
CFM+ manifold. The rough interior surface of the competitor’s
cast aluminum manifold causes additional turbulence.
It should
now be evident why there is a 44% increase in air flow over stock
and a 20% increase over the cast aluminum manifold of the competitor.
These tests were performed on a SuperFlow model SF-1020 Probench.

| Changing
to the CFM+ over the competitors cast aluminum aftermarket manifold
gives almost the exact benefit as replacing your heater grid with
a free flow spacer.
5.) The volume
of air that can get stuffed into the engine is also greatly affected
by the density of the air flow. This is why the material the manifold
is made of is so important. If the manifold’s material acts
to insulate the hot under the hood air from reheating the air flow
that has just come out of the inter-cooler that is a very good thing
for maintaining air density but if the material readily conducts
heat such as aluminum that would be bad since the hot under hood
temps would raise the air entering the engine since under the hood
temps are by definition higher than ambient or outside air temps
and heat flow is always from high to low temp. A materials ability
to allow heat to pass through it is called its Thermal Conductivity
represent by k in engineering equations. Aluminum has a Thermal
Conductivity rate or “k” of 236 W/M- °K. The CFM+
composite material’s Thermal Conductivity rate is, 0.25 W/M-°K
, which is 944 times lower.
Also the oversized
cast aluminum intakes present more aluminum surface area that absorbs
more under the hood heat and transfers it into the air flow.
CFM+'s advanced
engineered composite material is high strength and durable. (Fig.3)
