I saw a post about tyre pressure the other day and it remided me to go and get nitrogen put in my tyres.

I had it done at Bob Jane..it cost $20..I have had it in my cars before.There are a few benifits to be had by using Nitrogen rather than standard old air. Nitrogen is a denser gas.You dont need to check your pressure as it remains constant as it is not as affected by temp changes.Being more dense it may give slighly better ride and handleing ..... to me..the car feels more solid with the Nitrogen but not hard like it does if you put a lot of pressure in with air....with any luck it will help with fuel economy cos thats the only thing that I dont like about my Stagea...anyway if you dont change your pressures much you may want to give it a try...oh yeh having nitrogen in the tyres also seems to stop the tyes from flatening on the bottoms which tends to happen if you dont drive the car a lot.

One more thing.. cos I know somone will ask..yes you can mix air with the nitrogen if you need to.

You dont need to check your pressure as it remains constant as it is not as affected by temp changes.

hmmm not too sure about that one.

As soon as I read the bit about not needing to check tyre pressures, something didn't sound right, so I went looking for some more info and came across this:

The rubber used for tubes & inner liners in tubeless tyres is not 100% impermeable, therefore some pressure loss can be expected over time. This is one reason why regular pressure checks are necessary. Due to its molecular structure, nitrogen bleeds through the inner liner or tube at a slower rate than regular compressed air. This advantage applies to all tyres filled with nitrogen. Regular pressure checks are still recommended, as tyres often lose pressure due to slow leaks caused by punctures or valve leaks.

Regardless of what you have in your tyres, you should still check the pressure regularly.

Mmmm, where to start.

Nitrogen is a denser gas. Um no it isn't. The major constituent of air is nitrogen. The second most common elements if Oxygen. Which is more dense than nitrogen, so...

You don't need to check your pressure as it remains constant as it is not as affected by temp changes.

Sorry, but nitrogen, like any gas held within a constant volume (like air, too) will increase in pressure when heated.

Good salesmen at Bob Janes........

    • The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!
    • I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
    • Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
    • Thanks @jtha7 I will have a look around tomorrow but it is a prick of a spot. These are some photos i tried taking 
    • I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
