Like the GMC Syclone, the Typhoon is powered by a 4.3 L LB4 V6
engine with unique pistons, main caps, head gaskets, intake
manifolds, fuel system, exhaust manifolds, and a 48mm twin bore
throttle body from the 5.7 L GM Small-Block engine. With this
engine, the Typhoon produces 280 hp (209 kW) and 350 lb�ft (475
N�m) of torque. The engine is a modified version of the Vortec
engine found in the standard Jimmy, which originally produced 190
hp (142 kW). The engine uses a Mitsubishi TD06-17C/8 cm2
turbocharger producing 14 psi of boost and a Garrett Water/Air
intercooler, as well as revised intake manifolds, fuel system,
exhaust manifolds, and a 48 mm (2 in) twin-bore throttle body from
the 5.7 L GM Small-Block engine. The Typhoon sends power to all
four wheels through a 4L60 4-speed automatic transmission and a
BorgWarner 4472 (the Syclone used a BorgWarner 1372) transfer case
splitting torque with 35% forward and 65% to the rear wheels. Other
features include upgraded brakes, a limited slip rear differential
and sport modifications to the standard suspensions. Unlike the
Syclone, the Typhoon featured an air-operated self-leveling rear
suspension. The GMC Typhoon is a high-performance SUV, produced
from 1991 to 1993 by GMC. The Typhoon was based on the 1991 GMC
Jimmy. During tests by Car and Driver, the Typhoon was capable of
accelerating from 0-60 mph in 5.3 seconds, and could do a
quarter-mile run in 14.1 seconds at 95 mph. Car and Driver compared
the Typhoon's performance favorably to the Ferrari 348ts, Chevrolet
Corvette, and Nissan 300ZX Turbo.
