Aren't they meant to be driven like they were stolen???

Yes, you MUST keep the revs up I have found, if you are heavy. VP is 17 tonnes and trailer around 4 so that is the limit for combined mass.
If you let it bog down it just dies. Anything below 1500 is very verboten, I try not to go below 1,800 but sometimes find the change to 5th at those sort of revs does not go smoothly, that particular change requires lots more rpm at that speed and it just doesn't feel that natural.
I am sure it will all come easily enough, that is the only one I fluff sometimes now, they tell me the next stage is clutchless changing, er, maybe...

Yes 2200 sounds about rite to me, drop back about 400 revs on a change up with a RR any higher they sound like they will explode. Clutchless is the way to go Bill just takes some practice.

Bob I think William has a 6 speed Spicer in the bus.
I don't think they are a full crash box. I've never used one.

[Busman]

Yep they are a full crash box,I always though it was a non synchro (crash ) box or a synchro box and yes is a 6 speed spicer, but if you know where there is a 7 speed lying around...................

At 2500rpm the 92 would be screaming, a sniff of gas up around those revs will be quite noticeable. feed it in as a liquid between the turbo and blower would be the easiest but if you can make up spray bars under the blower and feed in as a liquid there you could get the injectors backed off a bit, or just ease up on the noise pedal till the black smoke is hardly visable, big torque increase then as it will hold the higher revs and should pull down to 1200rpm as the cold fuel will keep the turbo spinning, that is a very long power curve

at 2100 it is barely on 100 kph

ummm...... it's not a Ferrari it's a block of flats on wheels, pushing that much air faster than 100km/h takes a lot of fuel and develops a lot of heat

How is the injection going William? Will you use an EGT style probe/gauge too?

[Busman]

Haven't fitted yet, in Glen Innes at the minute for Minerama, with the extra radiator fitted we flew up here, on the way to Sydney for a class for my wife, then back to Brunswick Heads to see if we can get into Fleet again.
Am still thinking about adding the gas, is running so well now I wonder if it is worth it.
If you keep the revs up, no problems. I admit I would like a little more on the long slow hills, so maybe, time will tell.
Don't know if an exhaust gas temp gauge is necessary, we know it will run cooler and I would not use a kit that tries to add a graduated amount, the guys in the states with old GM's have had good success by just trickling a bit it ( 4 psi) for hills
