Terms of Use

Information only

The calculators and written content on Figureshed are provided for general information only. They are not engineering, mechanical, legal, financial or safety advice, and they are not a substitute for the judgement of a qualified professional.

Estimates, not guarantees

Several tools rely on commonly published rules of thumb. Real world results depend on many factors the site cannot see, including air and track conditions, fuel, traction, gearing, component condition and build quality. No result on this site is a promise or guarantee of a particular power figure, elapsed time, compression ratio or any other outcome.

You are responsible for how you use the information here. Before making decisions about an engine or a vehicle, verify the numbers with a qualified engine builder or mechanic and follow all applicable laws, safety rules and manufacturer guidance.

No warranty

The site is provided on an "as is" and "as available" basis, without warranties of any kind, whether express or implied. To the fullest extent permitted by law, Figureshed is not liable for any loss or damage arising from the use of, or reliance on, this site.
