How do I convert HP to WHP?
Re: whp to hp calculation? ( Just use a regular calculator. Just to be clear, if you’re assuming a 15% drivetrain loss (i.e. 100 HP at the crank = 85 HP at the wheels), then you need to take the WHP figures and multiply by 1.1765. In this case, 85 WHP * 1.1765 = 100.0025 crank HP.

Is 300 whp fast?
Assuming you mean whp, 300 whp is going to put you right around or a bit quicker a C5 Vette once moving. That’s a 290-300 whp car I think, albeit with better aero once speeds rise. You’ll outrun a 370 pretty handily at that power level as well. A new Mustang GT is going to have some legs on you when you get moving.
