HP does not allow you to maintain high speeds.
HP, technically, is an imaginary number, created by an algebraic equation which factors torque over time.
While it does give you an easier to understand indication of the correlation between torque and engine speed, it does not "allow" for anything.
Torque at 2,000 is the same as torque at 5,000, plain and simple as it gets. But if you only had Torque figures to rely on, you'd think that engine was puny at 5,000, because it makes so much less torque (in some cases, like my 300 I6 Ford) than it does at 2,000 RPM.
The figures are simple, when you actually know what they're for.
Torque = work performed (able to be performed)
HP = Work able to be performed in a certain span of time.
They mean nothing more than that.
And NO, a 90HP Subie WILL NOT make a 1/4 pass in 15 seconds. My 92 HP Civic could barely keep 16-17second runs, and it was nearly 1,000lbs lighter.
