Long story short, the Flyin’ Miata turbo set up is making 180whp on a Mustang dyno, as tuned by William Knose of Delicious Tuning. This would equal 225whp if it was on a Dynojet dyno, so we’re talking some really, really strong numbers from a stock 1.6 engine and MegaSquirt MSPNP2 ecu. Nice.
Please explain the two whp ratings that are dependent on the Dyno used.
Thank you.
The two main dynonometer types used are inertial–like Dynojet–and constant load such as an eddy current or water brake type. Because they work differently, different numbers are often generated by the machines. These numbers are further enhanced by correcting for the temperature and humidity during the time of testing. The bottom line is that the Dynojet is the most used dyno, and often produces numbers that are higher than other machines. In order to compare “apples to apples”, operators of non-Dynojet machines will factor in this difference. Therefore a 190whp reading for the Catfish on this dyno would read about 225whp on a Dynojet. whp means “Wheel Horse Power”, or the power measured at the rear wheels as opposed to the flywheel on an engine dyno.
