Estimate HP at the crank?

[1BAD89]

240 at the crank, that's being generous. Don't put on an aftermarket intake unless you have aftermarket heads, you'll feel no difference, it won't be any faster. The mass air is going to do nothing for you either, the cold air might add 1hp "maybe", the intake will add nothing unless you have aftermarket heads, and the cat-back "might" add 5hp. Unless you add heads, and a cam, headers aren't going to add much at all, if any hp. The off-road h-pipe you might pick up 5-10hp, but it's a good mod. I would say you'd be around 195-200rwhp if your car is in perfect tune.
