1987 Buick GNX
Lookin' good
The stock ride came in at 276hp/427pp, my mild tune brought that up to a respectable 402hp/477pp. Again, I found her very well behaved, not nearly as tail happy as the late 60,s - early 70's muscle cars I grew up with. With another 20 years development on those cars I suppose that is to be expected. The stock 4-banger had very long, well spaced gearing...the tuned versions 5-speed would take care of that. Brakes were nothing to write home about, but again, much better than the older muscle cars...they got the job done. Body roll was minimal side to side, fore and aft she would nose dive heavily under braking, but maintained control. No need to upgrade suspension or brakes on the tune. So, how did she do on the track?
Pass for the lead at Apricot Hill, two wheels on track is good...right?
For her first taste on track I chose the National-A, National Championship for cars with 500pp or less on SH tires. I selected the 3 lap event at Apricot Hill.
Stock: P2 @ -0.801 / total 5:17.428 / best 1:44.471
Tuned: P1 @ +1.018 / total 4:56.096 / best 1:37.xxx
That was fun and easy, too easy and the Buick was wanting more. So we took a look at the IB-Fighting muscle series for cars with 600pp or less. I went with the 3 lapper at Spa Francorchamps. The stock ride would be woefully under-powered by about 125pp, but the tuned version just may have a shot. As expected, even though the stock car got trounced by over 35 seconds, she did turn in a respectable P4, the lead group consisting of a Viper-ACR, Vette-ZR1 and a Viper SRT. The tuner turned into a real barn burner, luck of the draw gave me a tamer line-up: Viper SRT, Vette Z06 and a Shelby Mustang...no ACR or ZR1.
First pass for the lead, I take out the Viper at Fagnes, he gets me back at Campus...
Second pass for the lead entering Stavelot...
With the Viper and Shelby side by side making a run into Blanchimont I go low to block the Viper and the Shelby takes the lead on the outside...
Knowing the Shelby will go hard on the brakes and inside entering the chicane I let the Buick roll fast and outside, stab the throttle in the short chute and stand on the brakes exiting the chicane, this puts me along side the Mustang and on the inside for the final pass for the lead.
stock: P4 @ -35.70 / total 9:16.470 / best 3:03.305
tuned: P1 @ +.496 / total 8:46.316 / best 2:53.911
The tuned ride was a handful at Goodwood.
Goodwood Hillclimb TT, best of five runs:
stock: 0:59.579
tuned: 0:55.757
That was a blast, I don't think this will be the last of my on track antics with the Buick. Final verdict:
stock: sleeper
tuned: wolf in sheeps clothing 👍
