A Warm welcome to you (from a freezing Windhoek)
You might
have noticed that my Website has changed slightly.
This was
simply done due to input by some of you wanting to know ho to navigate my website or to generally find out
what it is about.
Please let
me know if these hints are helpful.
On a sadder
note, I had to increase the prices on my Camshafts slightly. Note that my
porting prices are still the same as a year back.
I try to
revise my prices no more often than every 18 months. This is to keep things
consistent.
Since I
last revised my Header prices over 2 years back,
the increase of 16 % was shocking but still well in-line with the industry
standard prices.
I believe
my Exhaust systems are more than
competitively priced, considering
I
use 2mm thick black steel tubing from 38 to 64mm OD. This is tough !.
Stainless steel becomes to Expensive and tends to crack
easier.
If there would be a demand for SS, I could supply tubing as
well as silencers on request.
But for now My Quality silencers are made of Galvanised
Mild Steel.
These Mild steel Silencers have the following features that
set them apart from the rest:
1.2 mm Single wrapped galvanised steel for better corrosion
protection and lower noise levels.
E-glass filling
Seam welded instead of crimping, eliminating leaks
I can have specific sizes and shapes manufactured –
depending on your needs.
Seeing that the Rand has depreciated
sharply against most foreign currencies, I am pressed to keep my prices stable.
If the USD
becomes worth more than 7.5 Rands, I will be forced to adjust (K&N’s are
currently a bargain being valued at 6.5:1 USD)
Since the
British took over Weber, the Carburettor prices are
climbing steadily.
The
question is; how long can people still afford to maintain their carburettors.
Even such
mundane items as the throttle shafts for the 36 DCD are not available anymore
and will have to be machined if the old ones are worn (not shot).
To convert to a Weber is still an option
right now, but for how long ?
I am not
trying to paint a bleak picture, but rather want to convince you that you
should consider your carb conversion now or go Fuel injection in the future.
On the
Weber Twin Carb conversion (2 Manifolds left @ 2050.00 incl) it is imperative
that the throttle cable is set up correctly:
Not fully
open 103 Kw @ 5530 Rpm & 204 Nm @ 3280 RPM Max CO 1.98 % (must be over 2 % not to cause engine damage)
Fully open
(WOT) 107 Kw @ 5680 Rpm & 210
Nm @ 3530 Rpm Max CO 2.21 % (set
up lean for best fuel consumption)
Imagine how
much more drastic the difference is with a piddly carb or Throttle body ?
It is
concerning to see these devices that clamp in-between the HT cable leading to
the coil or spark plugs.
Most of these
gadgets just have an internal gap (about 0.020") to make the coil
produce more volts to jump this gap and rotor/cap gap and sparkplug gap.
They are
normally marketed by a brand that calls them the “accelerator” or similar.
This device
is nothing but a capacitor that is mounted in series with your cable.
You can achieve close to the same, just file off 0.020" (Camaro Z28 spec of 1970's) off rotor arm or open spark plug gap by 5 thou / 0.1 mm to achieve same story with spark where you want it. With the resulting accelerated wear on all your ignition components.
A spark
plug cable does nothing more than transport the 20 000+ volts to your spark
plugs, which in turn ignite the mixture.
Any
resistance in the wire or “leakage” is disturbing.
The first you
measure with an Ohms meter, the resistance
of spiral core wires should run between 2 to 5 kilo-ohm max.
The 2’nd
you check in a dark garage with the hood open. If there is a “halo” around the
wire or wires, junk them.
Of course
interference is also a problem. To you listening to the radio it is annoying;
to your Computerbox it is little “deathstabs”.
Spiral core
makes more spark than solid copper, as solid wire does not give coil time
to build extra spark as jumps at lowest possible voltage. Carbon wires actually
absorb voltage and produce less volts at plug due to high resistance of carbon
core.
We sell the
premium stainless steel core Magstar wires at an
excellent price.
Bottom line
is a high output coil 33kv upwards with a decent sparkplug gap.

picture of the adjustable, single stage trigger for the Mauser K98 for only
R450.00 !
This trigger
is extremely crisp and is fully adjustable down to 2 1/2 lbs.

On a different note, 10 years back radio stations would invite you for a
talk and pay you in cash or give you a few free adds.
Today it has changed, as the Station now expects you to pay for
enlightening its readers. Interesting J
George Uys wants to sell his:
1998 Opel Kadett 1.8 iS 16V.
174000km
N$ 43 000.00
I hope this
Newsletter meets your expectation (if not, let
me know what you want to read about)

The
difference between ordinary and extraordinary is just that little extra!
