Sources & attribution

The Vehicle Type → Brand → Model → Generation → Engine → Tuning File hierarchy and the stock-vs-tuned HP/Nm values are aggregated from the following public web sources:

The following derivative components are created by DynoVault and are not present at the upstream source:

• Synthetic power & torque dyno curves, interpolated per fuel-type profile from the published peak values (labeled "illustrative" on the tuning page)
• The unified REST API with stable IDs, pagination, search, and per-key rate limits
• The cross-hierarchy search index with AND-token matching
• The tuning-options taxonomy as filterable chips, derived from the raw method/option strings
• All UI, copywriting, branding, and design (Cabinet Grotesk + Manrope + JetBrains Mono, racing-red accent palette)

The catalog auto-refreshes on a 30-day TTL: any brand whose last full scrape is older than 30 days is re-pulled in the background every 6 hours, up to 5 brands per sweep. You can see the freshness of each brand in the response via the last_scraped_at field (coming soon to the public API). If a source page changes structure, the affected brand will show stale data until the next scrape iteration — please open an issue if you notice drift.

If you represent a data source listed above and would prefer that DynoVault stop referencing your catalog, or if you'd like to discuss an official data partnership (licensed feed, attribution upgrade, revenue share), please reach out at admin@dynovault.net. We respond within 48 hours and prefer collaboration over conflict.
