HISTORY OF 131 ABARTH VOLUMETRICO Here is a brief description of this car from Sporting Fiats Club site: "During the Summer of 1980 FIAT presented two 131 prototypes to the European motoring press. These were based around 'blown' versions of the earlier 131 Racing/ Sport having supercharged 1300cc and 2000cc engines producing 115 and 142 bhp DIN respectively. The Abarth designed, positive displacement blower was belt driven and operated via a special Weber carburetor. This is a similar design to the supercharged versions of the 124 Spidereuropa and Lancia Beta Volumex but with a larger volume blower. In August 1981 these “Volumetrico’ 131’s were launched with 7.6:1 compression engines, oil cooler, electric fuel pump, special exhaust and a completely upgraded suspension and brake package. Their Pirelli ‘Plus One’ wheels and oval exhaust tail pipe were similar to the early 130tc Strada Abarth. All cars were assembled and prepared at Abarth. Other than the slightly lower ride height and rear ‘Volumetrico’ badges, there was little external difference to the standard SuperMirafiori series three. Except this one would take a lot more catching! Top speed was quoted at 101mph because of the 10/39 diff. ratio but, as with all the supercharged twin cams, the torque output was fantastic (21.8 mkg DIN at 3600rpm in comparison to the Rally 131 Abarth’s 18 mkg DIN!). 0 to 60 time is under 7 seconds. Fuel efficiency of the 2 litre was 24 to 27 miles per gallon. This bares comparison to any tuned twin cam prior to the modern Weber/ Marelli engine management systems. Impressive!"
