3 Rotor FD

Nicely written. FDs and Rx-7s are my favorite cars, and while it does get beneath my skin a bit to hear so many people calling them POS or unreliable, I usually just let it go without any arguement.. just because my opinion isnt going to change anyone else's, and partially because it may be deserved in some sense. The FD IMO is the perfect car, but it does have a few drawbacks that need attention. And even when everything is done to ensure proper working, every once in a while it can still bite you in the ass for no apparant reason. If Mazda had put the extra parts/engineering needed to update the cooling and turbo systems the car probably would have a much better reputation than it does today. However, the car probably would have cost an extra $5k on top of tha already steep high 30k range it was selling for (or not selling) in the early 90s. If you are willing to put up with the few headaches the car can throw at you, the reward is huge. I like my S2000 alot. Ive had it turbo'd, and I love how I can feel that I can boost it to 500whp and it still be reliable enough to take anywhere at anytime. (Something I couldnt always say with my FD). Ive been to meets and have drove/rode in S2ks with 4-500HP and modded to the gills, but it still doesnt touch the feeling my FD gave me even just ~320WHP and a nice suspension under it. Ive always thought my next car would be a Viper.. but Im going back to FD. My friends call me crazy, but its just a car that gets to you and I dont feel any other car out there right now has what the FD can deliver. My worthless $.02

at that speed, the weight advantage isn't a significant factor, but the better Cd is
Take 2 identical cars, but one with much less weight, the lighter car will walk away from the heavier one at any speed or from a standing start. A 2300-lb, 300-rwhp S2000 will walk away from a 2800-lb S2000 with the same hp from any roll-on or launch. It's proof that weight will always play a factor, but more or less depending on the scenario.

Since rolling resistance force is not a function of speed, then rolling resistance horsepower (a function of speed) increases proportionally with speed. Since aerodynamic drag force is proportional to the square of the car's speed, then aerodynamic drag horsepower increases proportionally to the cube of the car's road speed.
It is generally accepted that, on a typical car, its rolling resistance and aerodynamic drag become equal at about 50 mph. So at twice that speed the aerodynamic drag is about 4 times the rolling resistance

Uh, are you SURE you're an engineer? He said two identical cars (ie, power and aero) except for one being lighter than the other.
The lighter one will always walk the heavier one, all other things equal. Even at 400 mph, weight still plays a part, just a very, very minor part.

it might pull ever so slightly at 100+, but "walk", at least to me, means to pull away quickly and cleanly...not gonna happen
You obviously haven't had a fat passenger in your S2000. Try putting a 300-lb man in your car, then do a few runs, including roll-ons, and see how different the car will feel. It will be considerably slower and more sluggish. If you think weight will not have any effect (even from a roll-on), you must be living where there's no gravity. Gravitational force always dictates that weight/mass matters, but more or less depending on the scenarios.

A "walk" is generally considered as a steady but solid pull.

That would be a rape, not a walk. Walking is just a consistent increase in distance.
Walk is just what it implies - like walking away from someone, not running away. Slow but consistent pull ahead.
