The release of the WEVO SS Engine
Mount - the first non-solid Aftermarket engine mount developed specifically for
the 911 engine mount applications.
This WEVO SS Engine Mount is suited to the following applications:
911 1965 1971 Engine rear cross beam - 2 units
911 1972 1989 Engine rear cross beam 2 units and transmission mount 2
units
930 1976 1989 Engine rear cross beam 2 units
NOTE: A 914 transmission mount version is also available (W-914TRANS-BL). The
914 hole spacing is close but not the same as the 911 and the WEVO SS Engine
Mount body should not be slotted.
The WEVO SS Engine Mount is designed to offer virtually the same locating
advantages of a solid engine mount without the metal to metal contact between
the chassis and the engine.
The SS Engine Mount comprises of 5 components. The design of the components
ensures that at rest, or idle, the engine is firmly located, but free to vibrate
against the elastomeric pillows isolating the engine mount inner and outer
components. When the engine reacts to torque, the components deflect slightly
and the spring rate of the isolators is progressively increased, improving the
location of the engine and transmission under more stressful conditions. The
design is such that metal to metal contact is always avoided, so potentially
harmful misalignment forces and vibrations are managed in a manner more similar
to the original factory rubber mounts.
The SS Engine Mounts are installed using the original hardware and have a gold
anodized finish similar in appearance to the gold zinc plated factory parts. The
SS Engine Mount is an upgrade suited to cars used for spirited road driving all
the way through full race cars.
Testing on road and track cars has shown a significant reduction in vibration
transmitted versus solid mounts, without reduction in chassis performance, or
gear selection accuracy.
Owners of cars with Weber or PMO carburetors will be pleased to know that
development of this product was encouraged by Richard Parr at PMO as a way of
protecting against carburetor issues related directly to engine vibrations.
WEVO is now offering the option between the
standard "Blue" Pillows (P.N. W-911ENGINE-BL) and an alternate more compliant
"Black" Pillows (P.N.
W-911ENGINE-BK) for the range of WEVO SS Engine and
Transmission mount products. The new Black Pillows are 15 points softer on the
Shore A scale for durometer readings than the original "Blue" Pillows. The
Black pillows function in the same way as the Blue pillows although they allow
slightly more deflection under similar loads the advantage is lower noise
transfer through the SS mount module.
From our testing we would suggest the Black pillows for any street use only SS
transmission mounts. If you drive your car to the track would might also
consider these. For pure track work we recommend the original Blue pillows for
both SS Transmission and SS Engine mounts. The Black pillows are also good for
engine mounts on Street only cars offering a reduction of engine noise
transfer over the Blue pillows much less engine mount deflection and drive
train movement than the O.E. or O.E. Sport Engine mounts.
They have created this option to provide more flexibility in the WEVO SS product
range.
