Thereís a quite-simple
explanation for Cape Town tuning expert Robbie Ferroli
deciding that two engines in a Citi Golf was just the perk-up
he needed in life.
A long-time track racer at Killarney and on the club gymkhana
scene, Robbie was tired of breaking gearboxes in his quest for
more power out of a standard, single-engined, front-wheel
The way Robbie explains things, every time he managed to
extract in the region of three-hundred-and-fifty kiloWatts
from one of his Golf specials, the gearboxes couldnít take
the pain of three times the amount of power they were designed
The twin-engined project seemed like just the ticket. Keep
power "down" to about three-hundred kilowatts per
engine and he would have more than enough power to run the
sort of times on the quarter mile that had eluded him in
The starter-pack for the project was a one-point-six Citi Golf
body shell, which was stripped before all the components were
put into this mind-blowing street-racer. It took Robbie
Ferroli just three months to complete this amazing project
Robbie says he never sat down and drew any plans for the
project, but rather took things step by step.
The car uses two sixteen-valve Golf engines, a two-litre
engine in the front, and a one-comma-eight litre unit in the
But, as they say in the 0 8 hundred ads, thatís not all.
Both engines were turbocharged and each received its own
nitrous oxide installation.
The rear engine is located where the boot would be, and
according to Robbie, mounting the extra engine-package was not
as difficult as some would imagine.
He started by cutting out a section of the floor and welding
in a complete front engine installation from a Jumbo Golf
To make sure the rear wheels stayed pointing in the
straight-ahead position, Robbie locked off the steering rack
using two machined plugs.
In this way Robbie avoided having to make up countless
suspension components. And it has the advantage of providing
easily adjustable toe-in on the rear wheels.
Both the front and rear gearboxes are cabled-linked to the
gearlever. He says it was quite easy to ensure that both
gearboxes select the right gears simultaneously.
Each engine has its own separate starter and ignition
management system, as well as its own cooling and intercooling
system for the turbochargers.
Everything is doubled up. There are two gauges for revs, oil
pressure and water temperature, as well as turbo-boost on each
Robbie says his main problem was to squeeze all the radiators
and intercoolers into the available space in the Golf without
changing the exterior too much.
Apart from the wild colour scheme and roof-mounted rear wing,
he wanted things to look as stock as possible.
The layout in the rear of the car is a work of art. Some would
call it a plumberís nightmare, but everything is installed
with great pride of workmanship.
Items like fuel tanks and oil catchment tanks were all
purpose-made for the project in aluminum.
The car runs fairly modest street legal tyres on TSW rims, as
Robbie did not want to turn the car into a quasi drag racer.
He receives sponsorship from Yokohama for the tyres and the
way it burns rubber, that is probably a good thing!
Now when was the last time you saw a Golf spinning its rear
wheels like this?
Being effectively a four-wheel drive car, itís a natural
understeerer. The push from the rear wheels and the drive
forces on the front mean that traction on the front wheels
will let go initially in a corner.
The technique to get it around corners quickly is to
"pitch" the car into a corner with the accelerator
released, and then as the rear end starts to swing round to
apply the right amount of power and hold the car in a
Acceleration is phenomenal, with zero to one hundred coming up
in under four seconds. The car has run a ten-comma-six- second
Top speed is well over two-hundred-and-eighty kilometres-per-hour,
with more to come.
Robbie says that synchronizing the motors as far as tuning
goes is not a problem. Because they run independently of one
another, the one engine merely helps the other along, so they
never hold each other back.
With this Golf, nicknamed Double Trouble for obvious reasons,
itís a simply a win-win situation.
