We
have designed and developed the 3.0lt. Nissan V6, used in the Maxima
saloon, specifically for the SR 2 class in the SportsRacing World
Cup and Grand-Am series.
In its production form, the engine has a particularly good basic
design, the block and the heads are ideally suited for modification
to a competition engine.
Our design incorporates :-
A
new dry sump incorporating the lower main bearings, stiffening
the block. This allows the engine to be used as a stressed member.
A
new inlet manifold with roller throttles that acts as the base
for the air box.
A
scavenge pump system mounted directly on the sump.
It
is intended by the organising body of the series that the 38mm restrictor
limits the engine power to 350/360hp. We find that we do not have any
trouble in reaching these figures.
The engine has been designed to be capable of completing a 24 hr. race;
with that in mind, the rebuild life can be safely extended to 4000km.
But to keep the engine at its optimum, it is probably necessary to rebuild
it at shorter intervals, ideally every 4/5 races. If you ignore 24hr
races, this means one rebuild per season.
During the 99 season, the development engine completed 4500km of racing
and testing, without a rebuild. The engine was put back on the test
bed at 3500km and the power was found to be the same or better than
when new.
Results during
the 1999 season, were excellent. Two 1st, a 2nd and a 3rd places, giving
us second position in the drivers championship. In the 2001 season results
were, Three 1st, three 2nd and a two 3rd places. The Redman Bright car
winning the world championship.
IES can provide
engineering support during the season and will carry spare engines to
the races. If required, this engine can be leased on a per km basis.
