MINI COOPER S PHASE 5 - BBR COOPER TURBO 300
all about it August EVO Magazine - Where it hits 160+ mph!
Last year we decided, as there were serious
limitations with over speeding the original Cooper S
supercharger and although our big supercharger Cooper
S conversion was sensational, it would take turbo charging
to get big sustainable power from the S engine! So we
bought a new Cooper S just to turbo charge, then a few
weeks later a client called saying that he wanted ‘the
fastest Cooper S in the land’, enter Clive from
Bournemouth with his Cooper S.
We were already quite advanced in the
turbo system configurations and after offering up countless
system alternatives, we settled on the only real layout
that would achieve all the requirements of a high boost
turbo-layout, see picture.
The engine was stripped and rebuilt with
our big valve, BBR cam and ported cylinder head, mounted
on the BBR in house dyno, then run-in, mapped and power
tested. With the engine on the dyno, the chassis modifications
took place. Transmission was fitted with our limited
slip diff, BBR power grip suspension
added plus our big brake conversion.
After dyno testing, the engine was reinstalled
into the chassis, we fabricated the turbo layout. Comprising:
top radiator mounted intercooler assy and top mounted
air intake system, which replaced the original location
of the top mounted original intercooler. This gives
a sensational cold air intake stream. Oh and of course
we retained the Climate control too! The mechanics of
the conversion were completed by installation of our
BBR high flow fuel delivery system and injectors. All
in all it’s a very neat and tidy lay-out.
To finish it was then a simple matter
of extensive on road (real time) mapping to suit all
conditions of road use. With the huge power this conversion
provides with the smallest of throttle openings this
car would just take off!! To make this beast derivable
on lower throttle openings we needed a rethink.
The finished conversion offers 3 stage boost
control automatically switched by throttle position and
load. This stopped the beast launching itself to the moon
with light throttle openings, making it a very civil and
progressive car to drive through towns, villages and our
narrow English country lanes.
Turbo boost is available from as low as 2200rpm,
when on the open road, with full load throttle openings
a full 30psi (2bar+) of boost is unleashed from 3500rpm
right up to and beyond 7000rpm. Guys were talking quick
and quite possibly the fastest FWD 1600cc car in existence..!
Power is now revised 307BHP @ 6550RPM with 313lbs ft of
torque @ 5000PRM.
Price Fitted £17 950 inc labour, first 5 orders special
price of £15 950.
And if you want to know how it goes, we can
tell you it’s electrifying! It all adds up to the
fastest Cooper S in the land, just as our client ordered!
