These gears feel like I literally added a hundred horse power to the car. I ran around the street with 14#'s of boost on my old set up (3.73's). The identical set up with 3.27's on my new car is like night and day. I thought it might be a dog off the line from street light to street light, but if I rev it up a little off the line, and it flat out halls ass. Plus, the lower rpms on the freeway are a great benefit as well. I can’t wait to see the results at the track. I'm pretty sure my trap speed will definitely be higher.
