Toyota MR2 has surge in horsepower ia A 30 per cent horsepower increase to 145 lifts Toyota’s MR2 mid- engined sports car to a new level of high performance for the 1988 model year, “To many enthusiasts the roud holding and performance of the MR2 was the ultimate in automotive pleasure. But Toyota has redefined ‘ultimate’ by adding 30 supercharged horsepower to our only two-seater sports car,’ com- ments Toyota Canada senior vice president Hector Dupuis. ‘“‘MR2 is a car that fits like a glove, drives like a dream, looks like a million dollars and performs like a thoroughbred. This left only one area to improve on — straight line performance. That's where the supercharger fits in’? Dupuis con- tinues. The naturally aspirated, or non-supercharged, belt driven twin cam/16-valve MR2 continues in the 1938 model lineup. Its 1.6 litre 4A-GE engine horsepower output has been increased by 3 to 115 at 6,600 r.p.m. However, with the new 4A-GZE powerplant, Toyota engineers came up with even more horses under the rear deck lid by fitting a Roots-type supercharger, developed and manufactured by Toyota. Like a turbocharger, the supercharger forces air at above atmospheric pressure into the engine to increase combustion pressure and produce more horse- power. Unlike the exhaust-driven tur- bocharger, the supercharger is belt-driven off the crankshaft, supplying boost in direct relation- ship to crankshaft speed. The result is more horsepower faster, meaning almost instant throttle response which translates into greater acceleration plus increased top speed. To eliminate the supercharger’s main drawback, drag at low engine speeds which increases fuel con- sumption, Toyota engineers have developed an electromagnetic clutch and air bypass system that engages the supercharger as de- mand varies. During low and mid-range operation, when in- creased power is not required, a computer-controlled clutch on the supercharger input shaft is disengaged, idling the super- charger. At the same time, an air bypass valve is opened to redirect intake air round the supercharger. During acceleration and high engine load, the computer closes the air bypass valve and engages the clutch for full supercharger power. At steady operation over 4,000 r.p.m., the air bypass valve varies the amount of intake air go- ing into the supercharger, to regu- late overati boost pressure. During deceleration, the clutch disengages the supercharger below 4,000 r.p.m. The selective operation of the supercharger produces maximum fuel economy (8.7 litres’ 100 kilometres, combined vi- ty/highway) and helps provide quiet engine operation at cruising speeds. An added feature at the 4A-GIZE engine is new bi-diree- tional fuel injectors which provide direct injection into intake perts, reducing fuel adhesion to tic in- tebe duct, Uhus ensuring ides? con- didioas for the fuel air mone resulfing tn quick othe. ote respoaltss, Atthough premium unho id fuel is recommended for mapas performance, a regular/preniian switch is installed on the iustru- ment panel for use when it is not possible to obtain) premium See MR2 Page 28 ; Camaro Z28 f see.
