TVR POWER is pleased to announce
the arrival of the Taraka 500 engine upgrade demonstrator.
The car pictured above has benefited from one our
five litre upgrades as fitted to both Griffiths
and Chimaeras.
We realise that for some owners, the standard power
output of a 500 engine just isn’t enough,
so for those of you who feel brave TVR POWER has
developed a further range of engine modifications
to boost the power output of our already legendary
engines.
Visually, there isn’t much difference, apart
from the large bore plenum top and Samco silicone
hosing, but don’t let that fool you!
The modifications include camshaft, followers, pushrods,
rocker gear, inlet manifold, inlet trumpet base,
cylinder heads, plenum top & ECU chip.
CYLINDER
HEAD RE-WORKING
The cylinder heads are re-worked with balanced combustion
chambers and modified ports. All installed valve spring
pressures and heights are measured and re-worked to
TVR Power’s own specification.
INLET MANIFOLD RE-WORKING
The inlet manifold is re-worked with larger ports and
a modified trumpet base, and all inlet ports and gaskets
are matched and blended to remove any obstruction
CRANKSHAFT ASSEMBLY
All components in the assembly are re-balanced on our
own dynamic crank balancer to give a smoother, vibration
free delivery.
VALVETRAIN ASSEMBLY
The camshaft is replaced by one specifically developed
by TVR Power for this application, which is timed in
with a degree wheel for maximum power. This also enables
us to use “solid” mechanical lifters with
adjustable push-rods operating steel valve rocker arms.
PLENUM TOP / AIR INTAKE
The plenum top is bored out to over 70m/m and a larger
brass butterfly is fitted along with a specially machined
aluminium bell mouth to increase intake volume.
ECU EPROM CHIP
The standard 500 chip is replaced with one specially
developed for this up-grade, giving a smooth spread
of power throughout the rev range.
OPTIONAL EXTRA: BAFFLED SUMP
If you intend to do a lot of track-days in your car,
we would highly recommend that you have one of these
fitted. This will help to protect your engine from oil
surge and fluctuating oil pressure especially on circuits
where cornering speeds and loads are high. £225
+ VAT (Exchange).
OPTIONAL
EXTRA: THERMAL HEAT BLOCK
This is designed to block the conducted heat to
the plenum top and trumpet base, which in turn
keeps the air denser in the top half of the induction
system. It is made from a high density, aerospace
grade insulating plastic. £65 + VAT
OPTIONAL
EXTRA: HIGH OUTPUT COILS
With increased fuelling and compression, we recommend
a higher output coil to ignite the charge.
up to 45KV. Prices from £55 + VAT
