Rally_wgn. I agree 100% with you. As I keep trying to point folks back to your original post. However, there seemed to be some funny stuff going on with the "other" poster and his power claims which were being taken as "good tech" which seems to me just silly. A well sorted 2.5RS with a solid street motor that is well thought out I think would be supierior to a WRX with just suspension mods. Having driven a well-sorted 2.5rs with a true 50whp over stock, I can say that it's a hoot, especially around 7000rpm.
The simple math I posted is merely to illustrate that to expect that much power from simple bolt-ons is perposterous. You just cannot get that much power from bolt-ons on a modern NA car.
Wgn, keep on the track you are and I think you will be very happy with the car in the end. Just don't expect your girl to like it.
