With the
high output engines fitted in modern production 'sporty' cars, cooling
systems are usually adequate, but not engineered with a large safety
margin built in to cope with either our harsh conditions and/or
modifications. The most common way of extracting large increases
in power output is forced induction :- Turbocharging or Supercharging.
Extra heat is generated with the increased power output, some of it
going out the exhaust, some in underneath the bonnet radiation and some
into the engine cooling systemu. With modern aluminium heads now
universal and use of aluminium blocks becoming more common, increased
temperature travels to the cooling fluid and then into the radiator many
times quicker than previously, creating temperature 'spikes'. The
problem is that you don't see these spikes, or quick high peaks, in
modern cars because the manufactures have slowed the gauge needle travel
speed down many times compared to the old guages.The better these
temperature rises and spikes are controlled (quicker heat dissipation),
not only will the total power output be higher, but the engine wear will
also be decreased, especially the life of the headgasket (even more so
in a cast iron block/alloy head engine). An aluminium core is
between 18 and 38% better than copper/brass cores at this and these
thicker aluminium cored radiators are even more efficient on top of
these figures and when combined with the greatly increased safety of
T.I.G. welded aluminium tanks, eliminating the prone to crack crimped on
plastic tanks, combine to make these radiators very good value.
If you
desire a 'show car' look, or your application is not listed here,
contact ARE regarding our custom fabricated all aluminium
radiators.
The
longetivity of an aluminium core is al least twice that of a
copper/brass unit as long as you do not have stray current in the system
and you run an appropriate inhibitor, changed at the listed intervals,
and never, never, mix with any other inhibitors. The above applies
to any of the 98% of new cars registered in Australia, that now have an
aluminium core from the factory.
