The ELEVATE Volvo C30 T5 Performance Inlet Manifold (plenum)
is engineered and constructed to provide maximum power and torque gains
for the T5 engine. This is achieved by increasing both flow and capacity
when compared to the restrictive stock, plastic inlet manifold.
Careful attention to details throughout the manufacturing process
ensures every one of our Performance Inlet Manifolds perform exactly as
designed by our R&D team. Power gains are dependent on the state of
tune of the engine, but a stock T5 engines will see a power gain of
+14hp and +13ftlb (18 Nm), while a tuned engine with other ELEVATE
components will see gains of over +26hp and +22ftlb (30Nm) of torque
increase. The higher the engine output, the more effective our
Performance Inlet Manifold becomes as additional air flow is required by
Our Inlet Manifold is precision sand cast and heat treated to 356-T6
specification, creating a strong, resilient product. After casting and
heat treating, our Inlet Manifold undergoes a process of accurate CNC
machining on three different fixtures for proper alignment and inlet and
outlet port sizing for optimal flow. Every one of our Performance
Inlet Manifolds is then pressure tested for burst resistance. The final
process is the application of a high quality, durable and great looking
powder coated finish.
Optimized Air Flow Design: The inlet manifold takes the single
"inlet" of the throttle body and distributes the air between the five
cylinders. Our design optimizes the boosted air distribution between
the cylinders, creating consistent combustion chamber filling and
maximum power across the board. The interior surface of our Inlet
Manifold is coated with an epoxy coating for optimal, smooth air flow.
Outlet Port Size: The oval inlet ports on the stock lower manifold
which the inlet manifold bolts to measure 51.1mm x 32.4mm. The outlet
ports which mate to the lower intake manifold on the ELEVATE Performance
Inlet Manifold measure 50.2 x 31.8mm-a perfect transition in air flow.
For sake of comparison, the stock outlet ports measure 47.6mm x 29.2mm.
Compared to our competitors, the "Brand M" Inlet measures 47.6mm x
29.3mm and "Brand S" Inlet measures an average (very inconsistent
between ports) of 47.7mm x 30.7mm. Evenly distributed air delivery to
each cylinder is critical, and uneven port dimensions affect
performance. The factory plastic inlet has port variances of +/- .5mm
on width and +/- .7mm on height. Our competitors are not much better
than the factory inlet manifold in this regard. Only with CNC machining
can you achieve consistent port dimensions across all five ports. Our
competitors leave their outlet ports a rough, cast finish while ours
feature a finely machined finish that is coated for optimal flow.
Gasket instead of O-rings: The factory inlet manifold uses O-rings
around each of the five ports to seal to the lower manifold. This
design limits port dimensions. Our design uses a gasket which we
designed in-house and have manufactured to our specification. Using a
gasket instead of O-rings allows us to increase port dimensions to match
the larger ports of the factory lower manifold. The gasket has the
added benefit of blocking heat transfer from the stock lower manifold
(which is bolted to the cylinder head) to our Performance Inlet
Manifold, keeping the inlet charge cooler.
Burst resistance: We have seen and heard of several factory plastic
inlet manifolds bursting under higher boost pressures (even with a stock
turbo), causing significant damage underhood. The risk of this
happening is absolutely eliminated by our strong cast aluminum design
with robust wall thickness. We pressure test our Performance Inlet
Manifolds to 50psi (3.4bar) before it leaves our warehouse to ensure
proper sealing and burst resistance for our customers. Of the three
hose connection locations on the inlet manifold, both of our competitors
use plastic fittings on some of the connections which are prone to
failure with heat and time. All of our connectors are either zinc
plated steel or brass for strength and longevity.
Tailored to your car: Our Performance Inlet Manifolds are offered in
your choice of color to best match your car's style. Options are
Bright Silver with ELEVATE logo, Gloss Black with ELEVATE logo, and
"Stealth" which is semi-gloss black with no logo machined on top for
those that prefer their power making parts go unnoticed when the hood is
raised. If you prefer, you can also order your Inlet Manifold in a raw
aluminum finish (with or without logo) to finish yourself or set off
your engine bay.
Easy installation: Installation is easily accomplished by the
do-it-yourselfer with some automotive skill and hand tools. Premium
hardware and detailed instructions are included. Depending on your
stock air box style, installation takes between twenty minutes to an
hour and a half.
The ELEVATE Performance Inlet Manifold is a combination of excellent
power gains, top quality construction, and appropriate styling.
