You know, and I know....now you need to pull his head out of his *** for him, or tell him to put his money where his mouth is. Get some cash out this. This is an absolutely ridiculous argument. He'* horribly misinformed. My car weighs more than a Grand Am or GTP. I'd like to find one of his 'magic grand am'*' and have some fun with it. I've taken 2 stock GTP'* now.
That GTP will blow the freaking doors off of ANY grand am GT any day of the week, becuase of the torque of the L67 power plant. The stock motor in the GT is good for such a light car, but is in a totally different class.
GT in the grand am is more about appearance than performance. GTP is about raw low-end torque. Speed limiters on all these cars will be determined by the rating of the tires the factory shipped the car with. In our case with the SSEi, it'* supposed to be about 128 mph, for H rated tires. I don't know what the tire rating on the SLE, SE or SSE is, but they're limited to 108.
A stock non-supercharged Series 2 Bonneville will walk all over a Grand Am GT, also. It'* a fact of life.
This is like comparing a ford focus SVT to a 5.0 mustang. Same principle. Show him this, then give me his phone number so I can call and laugh at him. If he'* so convinced, tell him to prove it. Then you can look up the performance specs of both and shut him up for good!
