Specs you can check.

SpecAlmanac lists the specs of engines and machines the way a good owner's manual would: plainly, with the source for every number. No ratings, no "best of" lists, no guessing.

How we work

• Every figure links to where it came from: a spec sheet, a manual or, failing that, a retailer listing.
• When a brand measures something differently (noise at 23 ft vs. 7 m), we say so next to the number.
• When two sources disagree, we show the manufacturer's figure and note the other.
• Spot a mistake and we'll fix it within a few days.
