1987 Buick Grand National

       As noted on the previous page, the car ran 14.6 second standing start ¼ mile times in 90+°F weather with 92 octane gas and the original Goodyear Eagle GT tires (no traction) in stock form. I started to tinker with it around 9/88. Many changes were performed using tips from Red Armstrong of Quad Air. The various modifications brought the ¼ mile times down to a best of 12.19 seconds at 110.4 mph. The changes I did on my car are similar to the ones presented on the Buick Turbo Regal Recipe Page. Up to that point, the engine was not subjected to any internal modifications.

       After a few years, it was time to enhance the overall performance of the vehicle even further. The car received extensive modifications. The engine, transmission, rear axle, & brakes were all addressed. At this point the engine was outfitted with a 206° duration (@0.050" lift) Comp Cams roller hydraulic cam, a CAS stock location intercooler, Siemens #3102 55 lb/hr fuel injectors, Vigilante 5 disk lockup torque convertor with a #0 pump (~2800 rpm stall), and unfortunately, only 26" diameter slicks. A trip to the drag strip yielded a standing start ¼ mi. time of 11.203 sec. and a trap speed of 121.9 mph. That was with minor traction issues, running out of gear due to inadequate tire size, and operator error. The 60' time was a somewhat leisurely 1.64 sec.

      The setup was reevaluated and a few more changes were introduced. Obviously, the first thing was to acquire taller 28"D slicks. An HRpartsNstuff rear antisway bar was installed to ensure a straight launch. To improve the 60' time the torque convertor was restalled with a #6 pump (~3200 rpm stall). A slightly hotter 214° duration (@0.050" lift) Comp Cams roller hydraulic cam was installed. A liquid cooled intercooler was acquired. Lastly, Siemens #3145 72 lb/hr fuel injectors were installed to ensure an adequate fuel supply. To summarize the following tables present components and modifications the car has, at this time, to improve the ¼ mi. performance and overall handling. More to follow next year.
