Janspeed exhaust systems are built to complement our manifolds, built to the same high standards, and designed
to enable you to get the best from your car. Our 'straight-through' sound absorbent silencers minimise power loss
and giveyour car a pleasant 'sporting' exhaust note.
Exhaust systems are supplied unpainted or protected from rusting in transit by a NON HEATPROOF paint. For long
life we recommend the application before use of Janspeed VHT heat proof coating, details on page 15,

Every Janspeed carburettor kit undergoes extensive development to determine that it is ideally suited to the
engine. It is first tested on a static Heenan and Froude Oynometer then on a Sun Electronic Rolling Road and
finally completed on the road. The manifolds are internally polished and the whole conversion comes complete
with filters (excluding 40 OCOE kits), linkages, etc., ready for easy fitting. Manifolds are drilled and tapped for
Servo and other necessary off takes, and Weber 28/36 OCO kits ail have water heated inlet manifolds. Kits are fin-
ished in flame orange and attractively skin packaged for optimum protection. Weber 28/36 OCO carburettors are
compound type; OCOE are twin choke types.

Our cylinder heads are individually modified to the very highest standards and, for road use, provide a startling
improvement to a car's smoothness, performance and economy.
As a general rule a Stage 1 head utilises the standard valves and standard number of valve springs; Stage Il usually
involves a change in the type of springs and, in some cases, a changeof valves; Stage III, which is the ultimate for road
use, entails the use of special valve springs and enlarged valves and should only be used in conjunction with suitable
modifications to the inlet system and, in many cases, the camshaft .

Tu bocha ge ifs
One has only to look at Porsche's current racing programme to appreciate the intensive development and enormous power advantages
ofturbocharger systems. For racing application the requirements, and thus the development, are radically different trom a system
suitable for road cars but the principle isexactly the same; namely the driving of a turbine inthe exhaust manifold, by exhaust gases,
to accelerate and pressurise the petrol/air mixture inthe induction system and give greater efficiency and a substantial percentage
increase in power output.
Itwas our own racing development ofthe turbocharged Datsun 290ZG for the Dutch Datsun Dealer Team in 1977which prompted us to
investigate the feasibility of complete turbocharger kits for road cars.
The heart of our system isa TurboSonic turbocharger manufactured by Rota-Master of California, U.S.A. for which we are the sole UK
distributors. This and other hardware, such as the wastegate, for limiting turbo boost pressure, and the turbine lubrication system, are
imported by us to form the basis of the kits. We then manufacture the ancillary components such as inlet and exhaust manifolds and systems
for'the wide range of cars for which nspeedturboch rger kits cater.
Unlike traditional methods of increasing power output on production engines, the fitting of~ nspeedturboch rger kitsdoes not, inthe majority
of cases, involve any engine modifications other than drilling the crankcase to fit an oil return from the turbocharger lubrication system.
Furthermore, there is no other tuning system which gives such a radical increase intorque throughout the useable rev. band and engine power (an
/ildditionaI30 power at the rear wheels can be normally expected) and which retains the 'driveability' ofthe car at low engine speeds.
lnsimple terms, the turbine pressure boost is proportional to engine power output and in racing apRlications, the turbocharger isdesigned to work
on hiah pressure boost which demands a low compression ratio so as not to generate undesirable strains on engine components. ln the
nspeed
kit,
however, the turbo boost is purposely limited to between 5 and 7 p.s.i. so thafthe normal engine compression ratio can usual ly be retained. This has
enormous practical advantages besides removing the need for extensive engine modification as, on light throttle applications, the engine isoperating in its
normal aspirated state (without the turbocharger) and performance does not suffer the decrease inpower which isthe result of lower compression ratio
than standard. It also means that when the throttle is opened and the turbocharger cuts in, the powr increase is progressive with little appreciable lag.
Normal road applicationsfor turbocharging also include use on vans, motorbikes, and inparticular for cars when towing.
Apart from kitsfor many popular cars (adetailed list isavilable on request) we can supply a full range ofTurboSonic components trom stock.
These include a choice of three different basic sizes on turbochargers, available in 19different variations. This wide range makes iteasy to select the correct one
for ail engine capacity from 750cc to over 4-litres, and for any vehicle application. TurboSonic turbochargers incorporate carbon-sealed bearings enabling
them to be fitted up-stream ofthe compressor thereby greatly easing installation problems, improving throttle response and eliminating
'Turbo lag'.
The unique TurboSonic BPRWastegate is available in 5 settings trom 41bsto 111bsand can be supplied for exhaust pipe saddle mounting or a special sandwich
mount that fits straight onto the turbine.
Other accessories inc lude ignit ion advance/retard kits, water injec tion, prior ity valves, turbo silencers, adaptors for most American carburet tors , hea t shields
and boost gauges. Ali TurboSonic turbochargers are interchangeable with AiResearch units. CD

Smoother engine
The mass-produced motor car sold today on the world market is a compromise between many and varied statutory regulations and
the designers desire to produce a vehicle of maximum possible efficiency. The end result i s that most vehicles have considerable latent
power in their engine that can easi ly be employed to increase the driving pleasure and safety of a car where the laws are not restrictive
and high grade fuels are available.
Janspeed can improve the thermal efficiency of an engine by creat ing the best possible combustion condi tions so that the greatest
uti lisat ion is made of the fuel . This increased power can then be employed to benefi t the driver 's individual requirements . At a given
thrott le opening itcan achieve greater fuel economy and increased torque; these in turn give improved hi ll-cl imbing and over taking. Other
noticeable improvements are quicker starting and a more flexible, less stressed, smoother- running engine. Our customers have many varied
reasons for increasing the eff iciency of thei r normal road car, maybe for towing or increased overal l performance, or improved fuel
consumption or even for an occasional sprint or club rally. Each requirement can cali for a di fferent approach to engine modificat ion. For this
reason and due to differing local conditions in overseas markets we no longer offer suggested packaged efficiency kits for individual makes of
car. Al i the component parts are of course sti ll availabe and we are very pleased to suggest to you the best possible combination of parts for your
particular car tailored to your personal requi rements. These can be supplied for you to fit yourself, by your local garage or, if you prefer, by our
own skilied racing mechanics.
The fol lowing isan extract trom a
road test published in 'Car' magazine
of our Datsun 100A Cherry when tuned
with the sporting enthusiast inmind.
Itdoes indicate the type of improvement
that can be obtained quite easily and at
modest cost t rom the average small
family saloon. The car was fitted with
modified cylinder head, twin 1y, SU
carburettors, Janspeed exhaust manifold
and system . . . i t turned into a rea/ flyer . . .
the most impressive feature of the engine is its
wonderfu/ fIexibi/ity
. . .
i t s nothing short of
sensationa/ on the road .
This car was later fit ted with the optional
camshaf t and 'Cars Car Conversions' said . . .
What wou/d you think about a /eve/ road top
speed of 116mph. . . and a~60 mph time of 10.3
