We have based our Rover "K" series engine work on
producing a motor for sprints and hill climbing, to produce top end
power up to 8000rpm, and to maintain a good spread of power and
torque mostly for Westfield kit based cars.
Correct engine balancing is very important to eliminate vibration,
this also reduces wear and increases power output. We dynamically
balance all rotating parts individually. This means that each part
can be check balanced and replaced separately should the need arise.
Below are listed some of the modifications we have made to engines
built by us.
- Gas flowed cylinder head with standard or large valves.
- Pistons machined with deep valve pockets for performance
- Lightened flywheel retaining existing crank sensor
- Latest specification Piper cams (developed for
- Custom made inlet manifold to take carbs or throttle
- Standard injection can be modified with Luminition mappable
- Carbs with or without TPS for mapped ignition etc.
- Throttle body injection with DTA ECU and system.
- Supply and fit PACE PRODUCTS CATERHAM 'K' DRY SUMP KIT
- Custom build any pipework or bracket/fastener/body mods
required by any of the above items
All our engines can be used with I.T.G. filters or a Kevlar
Carbon Air box designed
by us complete with internal filter. Custom
made looms for ignition, injection or both combined.
Competition plugs, ignition coils etc.
The Piper cam kits are complete with special caps and
springs to cope with large amounts of lift using a duration
angle developed around touring car cams for a wide spread of
torque whilst still able to rev to 8000 plus. Higher revs and
more power is achievable with no obvious sacrifice in bottom
end torque. We also supply solid tappets to cope with high
revs and reduce the valve height and allow a kinder spring
rate than is normally possible
The crankshaft, con rods and pistons of the K series are
well engineered and use very tight and precise tolerances. To
enable us to dummy build these units we have designed and made
a torque plate and bolt kit so that we can stress the cylinder
block, to enable us to turn the crankshaft assembly
cylinder head in place. This is extremely useful when
measuring piston to cylinder head clearances for optimum
squish clearance, crankshaft float and running clearances. The
thrust oil feed needs to be modified if you intend to use a
race or competition clutch cover, also the Rover system of
grading main bearings is complicated and needs careful
consideration when ordering spares.
If the power output
needed exceeds 90 B.H.P. per litre and uses revs in excess of
8000 rpm then we would advise using stronger liners. This
requires a small amount of machining to the cylinder block.
Dave Brooks Engines
are able to supply complete motors or any parts needed for a
home build. We can also provide a measuring and calibration
service to help the home builder decide the best route to take
in building, modifying and ordering spares. We also provide a
rolling road service from basic car jetting right up to
programming of injection systems, fault finding and
troubleshooting. We stock and recommend Millers Competition
oils for use in pre cat cars, latest cat cars and early leaded
motors ( A series etc).
