Spinning Your Wheels: Here's Why Dyno Results Are Incomplete and Useless

The release of the Civic Type R has created a lot of buzz. The recent media launch generated plenty of opinions as to its performance, including some reviewers who believe Honda has underrated the CTR in the same manner it has done with the Accord V6 in the past.

Their speculation seemed to be proven true as a video released from a shop in Puerto Rico showed the car making 301 wheel horsepower. Many outlets reported on the dyno test and, while some showed the data with a little skepticism thrown in, others went all in and told us that the CTR has hidden horsepower.

The real truth behind the dyno test is that it is valueless. We do not have any data on its calibration or the weather, and the dyno operator could have applied any correction factor on the data to boost the results. This is not an isolated case in reporting sketchy dyno results, as I see it multiple times per month from various outlets and, in just about every case, the data and reporting are meaningless.

Piston Slap: Focusing on Turbo 93 Octane Tunes?

Sajeev,

Thanks for the recent advice on winter tires & wheels for my new Focus ST. I took delivery of the car two weeks ago and I’m having a blast. The first thing I did when I got it home was take Bark M’s advice and sign up for the Octane Academy.

So here’s another question: What’s your take on fuel octane and the ST?

  • ToolGuy This thing here is interesting.For example, I can select "Historical" and "EV stock" and "Cars" and "USA" and see how many BEVs and PHEVs were on U.S. roads from 2010 to 2023."EV stock share" is also interesting. Or perhaps you prefer "EV sales share".If you are in the U.S., whatever you do, do not select "World" in the 'Region' dropdown. It might blow your small insular mind. 😉
  • ToolGuy This podcast was pretty interesting. I listened to it this morning, and now I am commenting. Listened to the podcast, now commenting on the podcast. See how this works? LOL.
  • VoGhost If you want this to succeed, enlarge the battery and make the vehicle in Spartanburg so you buyers get the $7,500 discount.
  • Jeff Look at the the 65 and 66 Pontiacs some of the most beautiful and well made Pontiacs. 66 Olds Toronado and 67 Cadillac Eldorado were beautiful as well. Mercury had some really nice looking cars during the 60s as well. The 69 thru 72 Grand Prix were nice along with the first generation of Monte Carlo 70 thru 72. Midsize GM cars were nice as well.The 69s were still good but the cheapening started in 68. Even the 70s GMs were good but fit and finish took a dive especially the interiors with more plastics and more shared interiors.
