ZR-FUN


Here is Dave Prine's latest Corvette acquisition, a 1991 ZR-1. This car only shows about 28,000 miles on the odometer. Chevrolet built the ZR-1 Corvette between 1990 and 1995. The major difference between this Corvette and any other C4 Corvette is under the hood. General Motors teamed up with Lotus of Great Britain to develop an all aluminum 350 cubic inch overhead cam motor.  The motor features 4 overhead cams and 32 valves. The engine was actually assembled by Mercury Marine in Oklahoma.

Here's the heart of the beast, the LT5 rated at 375 horsepower in 1991, it was upgraded to 405 horsepower in 1993. The unique intake featured two ports per cylinder. There is a "valet key" that allows the owner to lock down the power to about 250 horsepower when you have to turn the keys over! Dave has had his car at the drag strip. He had trouble hooking the car up on the street tires, but still managed a very respectable 13.0 @ 113 mph at Speedworld Motorplex.

 

 

 

 

The original owner belonged to a ZR-1 club. At their meets you could get your verified top speed included in a sill plate. Dave's car ran a verified 180 mph!!

 

 

Only 28, 206 miles on the clock!

 

 

 

 

The car is actually 3 inches wider in the rear to accommodate the massive 11 inch wide Z-Rated P315/35ZR17 tires. The rear also featured a new convex fascia and four square taillights.

 

 

 

Some additional notes; all ZR-1's had 6-speed transmissions, the windshield had a special laminated solar coating. The ZR-1 was offered only in coupe configuration, no drop-tops here!  The suspension could be adjusted from firm to very firm, rather than from soft to firm found in earlier systems. The car was expensive, even when you considered all the high tech equipment. 2,044 ZR-1's were built in 1991, for which buyers paid an additional $31,683 on top of the cars base price for the RPO ZR1 option. All told, over a six year production run, 6,939 ZR-1's were built. The last ZR-1 built on 4/28/95 now resides in the National Corvette Museum.
