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.

  • Arthur Dailey What a load of cow patties from fat cat politicians, swilling at the trough of their rich backers. Business is all for `free markets` when it benefits them. But are very quick to hold their hands out for government tax credits, tax breaks or government contracts. And business executives are unwilling to limit their power over their workers. Business executives are trained to `divide and conquer` by pitting workers against each other for raises or promotions. As for the fat cat politicians what about legislating a living wage, so workers don't have to worry about holding down multiple jobs or begging for raises? And what about actually criminally charging those who hire people who are not legally illegible to work? Remember that it is business interests who regularly lobby for greater immigration. If you are a good and fair employer, your workers will never feel the need to speak to a union. And if you are not a good employer, then hopefully 'you get the union that you deserve'.
