The comprehensive horsepower calculator
Though I have designed it to work exactly the opposite to what most people think they want.
Most people want to tell a calculator what parts they have and have it guess at their current horsepower level ...
I've designed this calculator the other way around (on purpose).... tell me what your power goal is, I'll tell you how to get there ...
It is more valuable to help people reach their power goals, than it is to help them guess their current horsepower level and although it takes people quite a while to wrap their head around this concept.... when they finally do, they realize the value of what I've built here.
In the end, if you really think about it... horsepower is arbitrary ... saying I want to outrun my friend's 13 second WRX is concrete ... saying I want to have 320hp vs 360 vs 280hp is arbitrary.
The first stage of our calculator is a performance calculator that will help you find out how much horsepower is required (specifically for your platform) to hit a top speed, quarter mile, 0-60 or lap time... then we know how much power you really need... then we can tell you all the parts specs it takes to get you there.
Guessing at a specific power number is arbitrary. Allowing you to reach your power and performance goals is where it's at.
