Most HP applied at the tire signature, least weight, lowest AERO profile, best weight distribution, fastest/smoothest gear transfer, significant fuel/power ratio, least rolling resistance, best fuel/air to power efficiency, turning dynamics of wheels and tires (force absorption), equals WHAT? Good question... Is there anything I left out? How far can it go?
I'd say it equals too little time wrenchin' on what you've got and too much time thinkin' about what you may never get. Everything is a tradeoff. Sounds like you'll have a bunch of horsepower with a car that doesn't weigh enough to put the power down. On the bright side, once you get to speed the only thing that will slow you down is a hill.
