Will make you laugh!

He reved his motor and it had a supercharger

A direct quote from you... I assumed this whole time the Altima had a supercharger, because you said it had one. :shrug:

The Altimas curb weight is 3417 (for a 2009 3.5SE), and the Mustang is 3270 (actually a 1986 GT was the first one I found). Here we see a 147 lb difference when taking stock specs. The Mustang at 225hp, the Altima at 270hp.

Just grabbing info off the internet real quick, but it appears your number guesses for the cars might be skewed slightly in the Mustangs advantage.
 
I assumed he had one too. But people lie. Are you sure it was 3417 i find that one hard to believe. The Vette only weights alittle over 3300. Mines a Notch just alittle lighter. I've heard about 2950 so I'll just say 3000. But I'm not stock. But if and its a big if, he trust was dual supercharged and had 480 to the wheels at 30 psi he should have walked around me like I was sitting still.
 
Doesn't matter anymore what the guy had, it all history, a good story- but it sure must be nice to be able to use it at the end of January- we've got 6 or 7 inches on the ground, just got above freezing today, first day in 2 weeks!:notnice: Sounds nice up there Conneticut way too, just like here!:rolleyes::rlaugh:

This is true, I was referring to stock cars, not specific cars when quoting curb weights and power. A bolt on fox should walk a stock Altima, as it sounds like you did. Nothing wrong with that there, but to laugh at the guy (I dont mind you laughing at him, he sounds like he knows nothing) because he owns an Altima... that I don't understand, simply because a stock fox that we own, vs a stock Altima, the Altima should be on par with it.
