Denmark's fastest Alfasud

Denmark's fastest Alfasud.This orange Alfasud is the fastest car in the Danish Alfa Romeo Club Race Championship.It is made from ground by a person who is both a car painter and a panel beater (coachbuilder), so he knows how to make his own car as good as Safety first.possible. The car bases on a 1983 Alfasud 1.5 ti QV. The body was sandblasted an repaired for rust (not much) and strengthend on the known weak spots. After that it was epoxy-coated and painted in orange. The complete suspension is carried over from an Alfa 33 16V. The front antiroll-bar is from an Alfasud series 1. Together with some brackets it clears the 16V front crossmember.  The rear antiroll-bar is the one made by the Danish Alfaclub (a little modified). Yellow Konis were chosen as shock absorbers. The front coil springs come from a Mercedes, the rear ones were supplied by a Volvo. All the It looks quite usual - but wait till it races!suspension bushes are made of nylon and metal rosejoints are used (Uni-ball). A fast steering rack fromThe pilot's place. Tarox makes cornering more excact. The original 1.5 litre 105 bhp Boxer had to leave the car in favour of Alfa's strongest Boxer, the 1.7 16V. This engine was then further improved with a balanced crankshaft and a lightened flywheel. Racecams from Colombo & Bariani were installed and now work together with mechanic tappets instead of the serial hydraulic ones.An Iresa cross-over manifold and a home made 2,5" exhaust The 33 16 V crossmember and suspension.system allows the engine to "breathe" faster. The fuel injection has a EFI computer motor management system (type Euro 1). Specially made airboxes and nine sets of air intake trumpets with different lenghts make it possible to adjust the torque characteristic to the actual need. The power output is so raised from the serial 132 to 175 bhp depending on the trumpets used. Earlier it had carburators and 90 mm forged pistons giving a displacement of 1832 cc, but one piston broke. Due to delivery problems it now runs with standard 87 mm pistons.

So the (water) radiator moved to the back. Two electric fans assure a sufficient cooling. The engine has an electric water pump. The raised power of the engine made it necessary to install a stronger gearbox. A 33 16V gearbox with a lower final transmission ratio and a sinter metallic clutch now replace the serial clutch and gearbox. A Quaife Torsen antislip differential secures that the power is transmitted to the road without much wheelspin.

In order to decrease the car's kerb weight, the bonnet is made of aluminium and the windows are made of polycarbonate. In the interior you find a Sparco seat and seatbelt. The steering wheel and the rollcage are also made by Sparco. Maybe you will wonder why the exhaust pipe is bend to the left. The reason is that there are sound meassurements when the Alfaclub DK races.
When passing by "Start", the sound may not exceed 95 dB(A). The microphone for that measurement is placed at the right side of the track. Therefore by bending the exhaust to the left, the "result" is lower, making it easier to stay below the 95 dB(A). It is also the reason why the big airboxes are mounted.
