PLM GT2:
This is one wild looking GT2!
It has been fitted with MCA
adjustable shock absorbers which we believe to be the best
on the market, and the usual GT2 suspension bits including centre
lock wheels. The 4wd from the 996 turbo donor car has
been removed and the rear wheel tubs have been enlarged to
enable wider tyres.
We have stripped as much
weight as possible out of the car (without major surgery)
including the factory electrics and wiring and replaced it
with a Motec dash and ECU. The wiring is a light
weight Tefzel loom with helicopter style circuit breaker
switches on a custom carbon console. The weight
distribution has been improved by deleting the air
conditioning and power steering from the engine and
replacing with an electric power steering pump which is
controlled by the Motec. The end weight didn't quite meet
our target but is currently stands at 1210kg...
The roof scoop is now
functional and plumbed to feed the turbos via a custom
plenum and filter system. The engine Y pipe is now
custom fabricated to also improve the flow and aftermarket
intercoolers had previously been added. A short
ceramic coated exhaust mounted to the K24s ensures great
flames!

A switch to Garrett turbos,
internal engine modifications to ensure reliability and
sequential gearbox is planned for the future...

Time
is not my friend! The engine dyno makes
life easier on a project like this one,
especially when there were a few underlying
sensor issues and some weak coils. We
changed the coils to more powerful ones while we
were setting the engine up. That should
help in the future when we explore higher boost
pressures.
I
have always been a fan of drive by wire throttle
but I would happily trade the Variocam Plus for
a set of big cams! |

The
standard intercooler hoses are not my favourites
either and ultimately caused us to run out of time
and prematurely install the engine back in the car
so we had time to fabricate the air intake plenum
and piping and final details in time to meet the
deadline of the Shannon Nationals. Trying to
finish the tune on our favourite chassis dyno has
served as a harsh reminder how much easier these
engines are to tune when they are not in the car!
Simple things like the lack of background
transmission and roller noise and being able to
control temperatures are one advantage but even
simple things like reading spark plugs are a
nightmare with the water cooled engines! At
least the chassis dyno that we use is nice and
accurate but we still didn't get it finished in
time!
Hopefull the car will
be finished and tested in the next few weeks...
