It's fluid dynamics. He has a point that cooler air (denser) is more resistant to flow so will create more pressure loss through the exhaust (all things being equal). You are confusing this with absolute pressure/density which something like Boyle's law describes for a given volume. The 'zaust outlet on the engine 'sees' the sum total of the pressure losses through the exhaust system plus one atmosphere, not the pressure of an idealised gas where volume is held constant as temperature is increased. Pressure loss is government by viscosity, temperature, compressibility and density of air plus the friction factors and internal diameters and profile of the 'zaust system. All things being equal: Fat 'zausts = less pressure loss. Thin 'zausts = more pressure loss. How temperature loss of the 'zaust gases through the system (and the corrosponding increase in density) feeds into the equation I am not sure. It is certainly possible for a very cold, dense 'zaust gas, passing through a fat tube, to create more pressure loss than a hot, less dense 'zaust gas, passing through a skinny tube. Of course more pressure loss actual heats the 'zaust gas back up through friction, equals less density, so this is very complicated full of non-linearities and feedbacks. If you were a geek you could mount a pressure transducer in the 'zaust manifold and measure the pressure losses through the system.

Hot day? Sound a bit slow for that power.

Are you suggesting to hook it up direct to the battery?

The stock turbo has virtually no lag.

I should have known that Mr EPS would be into scooters.

Visibility is a good thing. I've been running headlights day and night since I did a defensive driving course in the middle east and was told to.

I drive with headlights on in the day.

I've got a motor speed controller kit from Jaycar.

It definately only came with two wires; power and ground.

I'd rather have a TVR Sagaris.

It's a Blitz mechanical one with a mirror finish. Needs to be lit up to see anything during the day. Thing is at night it is too bright. It's powered off the ignition at the moment. How can I dim it during the night? Resistor and switch?

er ok that makes more sense. Still I can't see the paint hanging around in the slots for too long, especially if you track it, the rotors can get red hot and the paint will blister and then flake off. If you want to be an ultra-geek you are probably hurting the cooling effect of the slots by adding paint.

The brakes will 'self clean' as it were; the pads will just strip the paint off the rotor and leave it shiny again. Seems a bit of a waste of time and effort though, may as well mask up the rotors as alluded to.

I don't believe a 32 can drive around in a 5.2 m diameter circle. A Hackney Carriage (London Cab) can only do it in 8 m and it is specially designed to have a very tight turning circle.

Where is the thermocouple mounted? I'd like to put it in the intake manifold area, but I had a look and there doesn't seem to be a viable place on the stock RB25 plenum. Was thinking of maybe poking a hole in the hose between the plenum and air inlet pipe and epoxy the thermocouple in there. It's a bit ghetto though and God forbid it gets sucked into the intake. On the link posted they tapped a thread in a plate and mounted the thermocouple in a gland, but there is no plate like that on the stock plenum? I'm interested to see heat soak so just a temp sensor near the POD isn't what I want.

Don't think the latter two GTR's you mention had stock suspension, but I'll leave that to their (ex) owners to confirm.

I asked in a local performance parts shop the other day and the guy said he didn't know of any available. I am thinking it would be cool to see the intake manifold air temperature. Can I just get a temp gauge and a thermocouple? I am bit new to gauge stuff, having just got a boost gauge and installed that (took me all day ).

The 32 seems to be lacking in decent bodykits...or at least that is my perception.

So that is what the cocks are in these days?

I'm not sure any chicks are impressed by a 20-something hoon in a Skyline.

He could be visually impaired for all we know.

Is that a fishing rod in the guys hand?
