One looks at HP numbers, sees a figure and thinks it will be enough.
But it never is. Get as much as you can afford, or the limit of what you think your engine can take, whichever comes first.

OK, you're going to do the SC thing, and so it begins again... more mods.
I'm hopeless, you're hopeless, we are all hopeless. It never stops.
