[Mustang_GT_90]

Horsepower on motor I don't know, and weight I don't know. The full weight GT weighs.
GT Hatchback Manual 3200 57.9/42.1
That is weight then weight distribution I forget where I got those numbers but somewhere off the web but those numbers are with no gas in the car.
Now my smog pump is gone and front sway bar and that's it so I'm gonna be brave and say if that's right then my car weighs 3150. Now gas I think is close to the density of water so lets say 8.6 pounds per gallon I normally run with about 10 gallons it so that's lets say 80 pounds there's 3230, then I weigh around 200 so there's 3430 race weight.
Now if you figure that up on a tech calculator then it's gonna say the car has to have like 273 horse to run that time. Stock mustang for my year is 225 horse, then lets say I add exhaust, headers. Lots of people claim more but I'm gonna say MAYBE 15 horse for adding headers, Prochamber, and Flowmasters. So that puts it up to 240 horse.
That is assuming that the motor has the factory horsepower it's supposed to be making which it really should, motor has 60K miles on it and has had a good life. All the ignition is up to par and I've got an electric fan on it taking some of the parasitic load off the engine. Also when we make a pass the motor is cool, intake iced, and it's like it's just been cranked up, an EFI car's best friend, then there's another trick with the timing which carburated mustang guys probably know all about.
Now I don't know how well one of those calculators can do using like the launch method we've been talking about because you're coming off the line with the motor way into the power range.
The numbers look like they work out pretty well to me.
The real fun thing is when you put numbers into that thing for a nitrous pass though, for example I put my 12.44@112.5 into it and:
Peak Horsepower: 349
Average Horsepower: 377
That just blows it's mind.
Sorry man I just guess I take it personally it seems like everytime somebody posts a stock number that is quick somebody always says it's not possible, nothing against you at all. There are a lot of stock cars that can run that time especially the speed density cars they're normally around .2 quicker. Some cars are just quicker than others, factory freaks , so just because one car can't do it doesn't mean no stock mustang can't.
