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...  Videos and more details soon...

 

Updates:

 

 

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...
