Good point, yes throttle can control and prevent wheelspin/traction loss.
In reference to the comments of [MENTION=7229]ThaCoyote[/MENTION] I am saying here that really anything much beyond 300whp is only going to be accessable on the drag strip or track - places where you can take advantage of that HP. Like Hijinx said, the power isn't always there, it comes on close to or at redline. So when are we at redline in 3rd gear? 85 or 95mph. When are we at redline in 4th gear? 115mph or so. My point is that this sort of power is great for drag or track use, but on the street it's pointless because you're never going that fast except for the occasional interstate fun.
Sure ThaCoyote your car will "hook up" eventually. But to say that you or any of us who are around or past 300hp are able to avoid any traction issues on street tires is absolute BS. Hijinx could speak to this - his car had big power, with a great set of suspension mods that kept it straight under acceleration, but from what I recall watching his videos he still had some loss of traction at WOT on the street and maybe on the strip as well.
