Sensor Location
For the intelligent water spraying kit, given the
option is it better to install the intercooler temperature sensor on the
intercooler (as in the guide) or on the air exiting the intercooler? Thanks for
any advise :)

It is normally much easier to measure the temp of the intercooler core, and so that is the approach
we recommend.
Numerous Errors
Hey, I'm reading
your new article
Heartbeat on oil
pumps and it's a great read. I'm dealing with a oil system failure as we speak.
However, the numerous spelling errors detract this article (and many others).
Please give your articles more of a look over before submitting them and/or
throw them into MS Office (or a free variant like OpenOffice) to spell check
them. Even Mozilla Firefox (as I type this) spell checks what I'm writing.
Now I know you guys are sound in your knowledge
but I believe the many typographical errors subtract from the confidence the
reader has in what he or she is reading. It's just human nature to disregard
information that isn't properly presented as if it lacks of credibility.
Thanks, keep up the great work!

Infrared Thermometers
Re
Infrared Temperature Measurement.
It is excellent to see this, especially the
caveat re emissivity as SO many people are ignorant about its importance with
certain surfaces. An important corollary of your point is that any surface with
a low emissivity will emit radiation at a lower rate than one with an emissivity
close to 1. There are plenty of examples of people chroming or silvering
surfaces for looks where this has the effect of making them cool more pooly, by
radiation at least. An example is the raw metal (aluminium) fins in some
radiators, especially replacements. If they are not painted matt black (or
even white) the emissivity of the metal surface is of significance and they are
not as effective in cooling as one might hope.

Wet Blanket
At the expense of sounding like a wet blanket,
have you folks thought through the implications of showing novices how to
electronically 'change' their cars? Not so many years ago making mechanical
changes to things such as steering required an engineers certificate. Now you
are encouraging people who have no knowledge of electronics to start tampering
with steering weight etc. Just a thought... other than that I enjoy the tech
articles.

We don’t regard altering steering weight as a
particularly dangerous mod. In fact, it’s easy to argue that allowing people to
change a flat tyre is a potentially more dangerous operation.
LPG Falcon
Having reviewed the
Falcon XR6 Turbo on LPG! so positively, how much
of your criticism of the new Falcon would have been removed if Ford had thought
to give it LPG injection and a gas tank that didn't fill half the boot?
Doctorpat

A review involving a used Commodore or Falcon
will always be more positive than a review of a new car, such is these cars’
rate of depreciation. That said, a modern, space-efficient LPG system on a
Falcon or Commodore would be expected to garner a positive
appraisal.
Diesel LPG
Great mag.
As I drive a diesel Safari (Jap Patrol) and would
like to use the new Diesel gas technology I have invertigated the two companies
that produce similar systems and both charge $4000 plus. I really don't believe
that there would be a lot of difference in the gas systems between petrol and
diesel gas systems . Sure the diesel gas computer would be different but if
anything I think it would be simpler if anything. Using the Gov rebate it may
cost you $500-$1000 for a petrol system but I think they are profiteering to the
detriment of the diesel owners. I rang one of the companies some time back but
they claimed very expensive components and high R & D costs. The word
bullshit came to mind.
Maybe this would make an interesting article for
Autospeed. There are lots of people with diesels that would like to use this
technology and I know from a friend that does a lot of towing, it really does
work. He has documented evidence to show the difference, with and without the
gas.
Regards and best wishes for the mag and
Xmas.

Snake Oil
I would like to ask if you are ever likely to
do any article on Hydroxy/ Electrolizer gas modifications and how to get them to
work successfully in a car. I recentlygot interested in this idea of being able
to put an electrolizer in my car and save on feul and posible increase
performance. I put one in my Toyota Tercel (don't laugh) but can't say I
conclusively that it made any difference, although my testing wasn 't done very
thoroughly as i sold the car soon afterwards. But i don't want to give up with
it quite yet. I now have a 96 Mirage (much better car) and would like to try
again with this. I also have a Pulse width modulater kit that I need to build so
your upcoming series on electronics should be helpfull as I'm a dunce when it
comes to this field.
Thanks for the great
articles

No we won’t be covering these topics. This view seems
a reasonable summary of the current situation.
P Mode
hi in your article
VT/VX Hidden Data in the setting where it
says p off and you say it is for police mode this is not the case and
someone has pulled your leg all it does is say p off when your lights are turned
off or it will say p on when you turn your lights on it just for headlights hope
this helps

Illegal in Australia
Just a quick message with regards to your
re-published article
Butterfly Effect on
the subject of exhaust valves. Unfortunately these valves are now illegal in
most parts of the country by virtue of recent legislation.
The NSW DECC website says:
"The Regulation also makes it an offence to use
temporary noise reduction devices or packing on vehicle exhausts. This includes
items such as baffles in the exhaust system that have not been welded/riveted in
place, or items that are adjustable such as valves, or materials introduced into
the exhaust system, such as steel wool. These items must not be used to defeat a
noise test."
Note that vehicles fitted with such a device from
the factory are excluded.
