Find a Dyno — Public & Shop Dynos

Dyno facilities you can rent for baseline pulls, tuning sessions, or shootouts. Filter by dyno type (Mustang, Dynojet, AWD, 2WD) and location.

Last updated 2026-04-30·Open Dynos

A dyno session is the only objective measure of what your build is actually making at the wheels — and the controlled environment that makes serious tuning possible. The dyno directory lists facilities you can rent for baseline pulls, tuning sessions, before-and-after numbers, and shootouts.

What you can find on /dynos

  • Dyno type — Mustang (load-cell), Dynojet (inertia), Dynapack (hub), AWD vs 2WD, eddy-current.
  • Power range — most dynos publish a max sustainable load. High-power builds (1000+ whp) need to filter to facilities that can actually hold them.
  • In-house tuner — some dyno facilities have a tuner on staff, others rent the dyno only and bring-your-own-tuner.
  • Hourly vs per-pull — pricing model varies. Hourly is better for tuning sessions; per-pull is better for a quick verification number.

Dyno types, when each matters

  • Dynojet — inertia-based, reads optimistic. Most published numbers in enthusiast spec sheets are Dynojet. Best for quick pulls and trend comparisons.
  • Mustang / Mainline / Dyno Dynamics — load-cell or eddy-current. Reads more conservative. Best for tuning under sustained load and replicating real driving conditions.
  • Dynapack — hub-mount, removes the wheel/tire from the equation. Great for very-high-power cars where wheel slip on a roller is a problem. Setup time is longer.

Comparing numbers across dyno types is a lossy operation. Two dynos of the same type at different facilities can read 5–10% apart. When sharing or interpreting numbers, always cite the dyno type and facility — "405 whp on a Mustang at Sheepey" is meaningfully different from "450 whp on a Dynojet at the local hot-rod shop."

What to bring to a dyno day

  1. A car that runs cleanly under part-throttle and has been warmed up. Don't bring a half-finished build.
  2. The fuel you actually run — if you tune on E85 and arrive with pump 91, you've wasted the session.
  3. A datalog tool if your tuner needs one for the platform.
  4. A plan for what each pull is for — baseline, post-mod verification, full tune session. The facility's rate goes a lot further when you arrive with a plan.
  5. Tape (real tape, not painter's) for any louver / bumper / vent that might separate at speed.

Frequently asked

How much does a dyno pull cost?
Per-pull verification: $50–$150. Hourly rental for a tuning session: $150–$400/hour. Some facilities bundle 3–5 pulls for $200–$300. Each facility's page on /dynos shows their pricing structure.
What's the difference between Mustang and Dynojet?
Dynojet is inertia-based and tends to read optimistic. Mustang (and Mainline, Dyno Dynamics) is load-based and reads more conservative — typically 5–15% lower on the same car. For tuning under real-world load conditions, a Mustang-style dyno is more useful. For quick comparisons against published numbers, Dynojet is the more common reference.
Can I bring my own tuner to a dyno?
Most facilities allow it — a dyno-rental rate for the room and a separate fee for the in-house tuner if you use them. Confirm the policy before booking, especially if your tuner is remote and will be on a video call during the session.
How do I find a dyno that can handle 1000+ whp?
Filter the directory to facilities that publish a high-power rating. Dynapack (hub-mount) is often the best choice above ~700 whp because it eliminates wheel slip. The facility's page lists peak-rated power; if it's not listed, ask before driving over with a high-power build.
Are dyno numbers comparable across facilities?
Roughly, but not precisely. Same dyno type at different facilities can vary 5–10% due to calibration, weather correction, drivetrain-loss assumptions, and air density. Always cite the dyno type and facility when sharing numbers, and use the same dyno for before-and-after comparisons whenever possible.
