Valkyr: :lol
I
drag raced and autocrossed my ~400hp Mitsubishi Eclipse GSX for 10 years (11.8@118mph was my best). I launched the sucker at 4500 to 5500RPM every single run. I never broke a single drive line component while launching. Now, you do have to launch it right, though. You need to slip the clutch out very quickly, not side-step it.
You do tend to burn through clutches a bit more quickly, but they still lasted 2 to 3 years worth of drag racing and daily driving.
And there are upgraded transmission options for my car, like dog boxes with straight cut gears, that will make it able to withstand just about anything. They are around $5000 which is more than I would want to spend on my car. A friend of mine has one, though.
I have no problem buying the top transmission option in Forza, though.
And it whines just like a straight cut dog box does.
