1999 Buick Regal GS

[Bob Trieschmann]

A friend of mine that I drag race with has a 99 Buick Regal GS with the 3.8 supercharged V-6. He wants to know in his car what is the final drive ratio. Is it a 2.97 to 1 or a 3.08 to 1 ratio? By the way this car with a Thrasher cold air intake, 3.25 supercharger pulley, and drag radials has run a best of 13.76 @ 99mph. Pretty impressive for a FWD car.

It's 2.93 on our cars.

Hope this helps,
