|But with a custom-made
air to air intercooler – a device which can dramatically
decrease the temperature of the air fed into the engine
and therefore increase the density – and appropriate
engine remapping to suit, the smaller engine gets a massive,
36 percent power boost.
|The first tier of this
conversion is the Power Plug, a product designed specifically
for modern electronically-managed turbodiesels, giving
the expert tuner the ability to set fuel quantity and
injection timing on a engine ‘map’ which has
nearly 500 individual points.
|With the upgraded electronic
control managing the diet of fuel as well as freshly cooled
air, output has been increased from 74 to 102 kW, with
no loss of durability or reliability.
|The reliability is a direct
result of the lower combustion temperatures, which means
far less chance of detonation and also brings with it
lower exhaust gas temperatures.
|In one fell swoop, the
SAC ethos of meeting both performance and reliability
concerns were met.
|“As always, our objective
has been to improve both power and economy without sacrificing
durability or driveability,” says Steve Fischer,
who founded SAC nearly a quarter of a century ago. “By
using a sophisticated product like the Power Plug to manage
the electronics, it has become possible for the skilled
tuner to achieve what used to be considered disparate
|In independent testing
conducted on behalf of SAC at Highveld altitude, the single
cab Hilux used for research and development managed a
true top speed of exactly 156 km/h, and a terminal speed
of 150 in a 1,8 kilometre standing start compared to 136
km/h when standard.
|The best news is how dramatically
the driveability improves however.
|In fourth gear, it takes
just 13 seconds to accelerate from 80 to 120 km/h (an
increment which is a very good measure of overtaking acceleration
in the real world) compared to 19,4 seconds in showroom
|That’s only part
of the story.
|The beauty of the modified
Hilux is just how smooth and refined its performance is.
|It feels like it is always
pumping and there isn’t a hint of turbo lag when
you put your foot down at any speed in any gear.
|But there certainly isn’t
a wild and uncontrollable rush that throws the passengers’
heads back either . . . just a pleasant and steady delivery
|The good news is that this
conversion is also applicable to the increasingly popular
Toyota Quantum van and bus, as well as all other models
in the Hilux range powered by the 2,5 D4-D powerplant.
|The latest RAV4, just recently
introduced in with a 2,2-litre 100 kW intercooled turbodiesel,
would also benefit from the Power Plug portion of the
|Customers can order the
Power Plug as a standalone, or the electronics and the
intercooler together as a ‘stage two’ conversion.
|Prices are R4 950 and R10
950 respectively, though there are more affordable alternatives
within the SAC ‘menu’.
|These conversions can be
carried out at any of the 11 SAC outlets in all major
centres in South Africa.
|All work carried out by
SAC comes with a six month, 20 000 km Why Worry warranty.
