Lap times improved from 18.72 seconds to 6.44 seconds. Read on to find
out how we did it.....
Frequently the older Scalextric cars can seem slow and difficult to
race by the standards set by modern Scalextric cars. This article shows
that in seven simple steps a typical Scalextric car from the 1970s can
be updated to give track times nearly 3 times faster compared to the
car when found. This was all accomplished with some basic servicing
and with some readily available replacement parts.
The older Scalextric cars from the 1970s and 1980s are great models
but can seem slow and difficult to race by the standards set by modern
Scalextric cars. Luckily these classic Scalextric cars can be upgraded
to greatly enhance their track performance making them competitive on
the track while not removing any of the enjoyment and skill required
for the older Scalextric cars.
This article lists seven simple changes to greatly improve your classic
Scalextric car. We have based this article on a 1970s Scalextric C.052
Ford Escort RS1600 which was selected as being typical of the Scalextric
cars of the period. It was not prepared before the test apart from ensuring
the motor operated as expected and the car was complete, electrically
and mechanically with no obvious faults. The tyres were not cracked
or split to any great degree and still had grip when run on classic
Scalextric track. Our overall impression is that this car had been stood
unused for a long period of time.
The seven steps
The results are based on a Scalextric Sport track with a test circuit
specifically designed for this test. Built from the modern Sport Scalextric
track the surface offers little mechanical grip with a smoother surface
compared to the original classic Scalextric track. It incorporated tight
inner corner hairpin sections, long straights, chicanes, corners that
tightened, corners that opened out. Essentially all types of challenges.
Step 1: After conducting a visual inspection we measured
the best lap times the car could achieve. The best lap time achieved
was 18.72 seconds. Then the car was given an electrical service with
new; copper pick up braids, pick up pins and wires from the pick up
assembly to the motor. A retest gave a new lap time of 15.22 seconds
which is an improvement of around 18%.
Step 2: Then, the car given a full lubrication service
with all the motor and axle bearings given a small drop of oil each.
Also, the gears were lightly coated with Teflon impregnated grease.
A retest of the car gave a new best lap time of 13.77 seconds which
is a further improvement of around 9.5%.
Step 3: After the lubrication service slightly wider
axles were fitted and a little weight added to the rear of the chassis.
Again the car was tested of the track and this time gave a best lap
time of 12.50 seconds which is an improvement of 9.2%.
Step 4: Next a set of high grip replacement SuperSlix
tyres were fitted to the rear wheel hubs. A retest gave a new best lap
time of 9.99 seconds which is a further 20.1%.
Step 5: With the improvement made so far the next
step was to replace the original Johnson motor with a new Mabuchi motor.
This more powerful and lighter motor slightly increased the car’s
lap time probably due to problems in getting the power down to the track.
The best lap time recorded was 10.49 seconds which is a degradation
Step 6: In order to give the car a chance to use the
power available from the Mabuchi motor a Neodymium magnet was added
to the chassis of the Escort. The best lap time achieved was 9.12 seconds
which was an improvement of 25.5%
Step 7: Our final change was to add MAX Grip tyres
as some tyre slip was clearly evident even with the Neodymium magnet
present. These replacement SuperSlix tyres are manufactured from a latex
material and give outstanding track grip. The best lap achieved a time
of 6.44 seconds which was a further improvement of 25.5%
The overall improvement in lap times make this car competitive on the
track while not removing any of the enjoyment and skill required. With
these simple changes this car was almost a staggering 3 times faster
than when purchased.
