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.
