so to sum it up, with adding an electric fan ($200) and a sn-95 alternator, i picked up nearly 15-20 hp at the rear wheels and get better mileage. some people are lucky to get that to the rear wheels after head work. brian

How on earth do you think putting an electric fan on gave you 15-20hp at the wheels? Did you have it dynoed? Do you realize that is like 30hp at the flywheel?! There's no way. Otherwise I must have gained that much or more from removing my smog pump and A/C?! I don't hink so. More like 5hp at the flywheel if I'm lucky.
