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?

  • Jeff I doubt most people care. Care more about their vehicles but after being a loyal gm customer for almost 50 years and having family members all the way back to my grandparents I no longer care. The last gm vehicle I owned was 2 years ago. To me gm can go into the dustbin of history.
  • Cprescott I'm surprised they didn't move to China. That is who bankrolled their bankruptcy bailout plan.
  • Analoggrotto You ask as if I should care. Well I don't. Any more questions?
  • Analoggrotto What the heck are those people doing in front of that house? Just staring at this stupid pos truck?
  • Jeff Good review but the XLT although not a luxury interior is still a nice place to be. The seats are comfortable and there is plenty of headroom. The main downside is the limited availability resulting in dealer markups above MSRP. I have a 2022 hybrid Maverick XLT for over 2 years and it has more than met my expectations. I believe for many who do not need a truck most of the time but want one the Maverick will meet most of their needs.
