450nm? wow

They are torque monsters mate, because they run a restrictor on the turbo we get as much boost in them as possible with a responsive exhuast wheel. We are getting over 25psi at just over 3 grand and they start tapering them.

The secret with a restricted turbo motor is torque thats why the WRC cars make a shitload more torque than HP and they run a 32mm restrictor.

Turbo restrictors

The turbo restrictor's effect is mostly noticed in high engine RPM (above 5000). In this region of operation, the engine's output is very dependent on air flow. This is why engine heads are ported and air intake channels are polished to optimize air flow. The restrictor's effect on engine torque is beneficial. Peak torque values are obtained in medium engine rotational speeds. The presence of the restrictor, which actually accelerates the gases flowing through it and directs the to the center of the turbocharger's compressor wheel, essentially increases the engine torque. We can roughly estimate the drop in engine power to be as high as 40% whereas the engine torque can be increased, through appropriate engine management, by around 20%.

Torque will be handy up the mountain but conrod will be a PITA, as they run out of puff at 6grand, they will rev to 7 pretty easy but the turbo is then down round 10psi. There is a guy from Tassie coming over with his brand new BA GT replica with a stone brothers 6 litre V8 in it. His last one in his old car made 717hp at the flywheel and this is meant to make a bit more

I rang the Abercrombie Motor Inn today, a good budget joint where MSN & I stayed least Easter - very close to trackside. Full up I'm afraid but they forwarded me on to Bathurst Tourist Council who said there was still accommodation available locally, as they had just completed a phone survey yesterday. They were going to e-m me their list (which I was going to post up for you) but it is yet to arrive

Thanks for that mate, I might give thema call also and see what is available, you coming down for a look, should be a good event.

Edit... We have accomomdation at Bathurst at the Country Lodge Motor Inn, that will be heaps better, closer to the track and pubs Thanks again Nota, I found out my brother phoned 2 motels both were full so he gave up and booked at Orange.


He has now been sacked from Travel and Entertainment co-ordinator
