excuse my ignorance but???????

i saw it at the brissie motor show. There are several firms that advertise it in the Yellow Pages.

Endrust on the Gold Coast has a specialon it (electronic rust prevention) at present.

has anyone any knowhow on this?

my step dad has it on his hilux ute so i know exactally what you're talkin about!

he lives about 1km if that to the ocean and over the last couple of years so far so good, no rust!

mike: it's a device that sends electric pulses through the chassis of the car, and apparently it prevents rust from developing

Yeah there is a company that supplies units to the gold coast lifsavers for thier equipment they run on the beach to prevent rust in them.

Apparently they work by putting a special current through the metal and it keeps away rust...?

Dont really know if they work or not?

I'm no chemist, but i seems to me it would be a simple redox reaction. similar to how the old lead acid batteries worked? i remember doing chemistry at uni and it had equations that were similar to that, but using lead and copper instead of iron (steel)

Maybe something like Fe + O2 -> FeO2 + energy

then the reversible reaction would be FeO2 (rust) + energy (our current) -> Fe (steel) + O2 (oxygen) therefore no rust develops

this is from very limited chemistry, i'm sure it's more complex than that

sounds like u know a fair bit, i sure dont remember anything from my old skool days :)

einstein(sp?) in the house :)

I know less then Terminal,

But I believe he is right - rust is the result of a simple chemical reaction b/w the electrons in metal and the oxygen in the atmosphere. The presence of moisture speeds up the reaction as it is a good conductor.

The whole electronic rust prevention idea works b/c it is based on sound scientific knowledge, but I read somewhere (or maybe heard it on Dr Karl) that you would need lots of electrodes all over the car to provide adequate protection as the area of influence is relatively small. Otherwise you would need a fairly large electical current running through the car body.

Hehe, nah i'm only a year out of my engineering degree, so i still have a bit of that 'learning' left in my head. give me a few years and i'll forget it.

units apparently come with more "contact points" as the vehicle gets larger. about 8 points for Stagea size.

    • I myself AM TOTALLY UNPREPARED TO BELIEVE that the load is higher on the track than on the dyno. If it is not happening on the dyno, I cannot see it happening on the track. The difference you are seeing is because it is hot on the track, and I am pretty sure your tuner is not belting the crap out of it on teh dyno when it starts to get hot. The only way that being hot on the track can lead to real ping, that I can think of, is if you are getting more oil (from mist in the inlet tract, or going up past the oil control rings) reducing the effective octane rating of the fuel and causing ping that way. Yeah, nah. Look at this graph which I will helpfully show you zoomed back in. As an engineer, I look at the difference in viscocity at (in your case, 125°C) and say "they're all the same number". Even though those lines are not completely collapsed down onto each other, the oil grades you are talking about (40, 50 and 60) are teh top three lines (150, 220 and 320) and as far as I am concerned, there is not enough difference between them at that temperature to be meaningful. The viscosity of 60 at 125°C is teh same as 40 at 100°C. You should not operate it under high load at high temperature. That is purely because the only way they can achieve their emissions numbers is with thin-arse oil in it, so they have to tell you to put thin oil in it for the street. They know that no-one can drive the car & engine hard enough on the street to reach the operating regime that demands the actual correct oil that the engine needs on the track. And so they tell you to put that oil in for the track. Find a way to get more air into it, or, more likely, out of it. Or add a water spray for when it's hot. Or something.   As to the leak --- a small leak that cannot cause near catastrophic volume loss in a few seconds cannot cause a low pressure condition in the engine. If the leak is large enough to drop oil pressure, then you will only get one or two shots at it before the sump is drained.
    • So..... it's going to be a heater hose or other coolant hose at the rear of the head/plenum. Or it's going to be one of the welch plugs on the back of the motor, which is a motor out thing to fix.
    • 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.
