It really makes you wonder, why the hell do we even have dynos? Mustangs read notoriously high, dynojets low, and hell dynapacks dont even account for the wheels! They are bolted onto the hubs. Thats why I really dont find the need/want to put my car on the dyno. My car makes what it makes, maybe 110 horsepower, maybe 1000, My view on how fast it is, is that once its tuned, itll be fast enough.
I DONT THINK SOOOOO...Its pretty much common knowledge that Dynojets read higher then everything. Superflo's DynoDyanmins, and Mustangs all read much moer accurately. Of cpurse It's all comes down to the operator. If they dial it in correct then they "should" all read the same... Unfortunately this is a time consuming process, and most operators don't take the time to do so.
Hahah thanks Blair for calling me out :oops: ...I Was hoping no one would catch it. You must remember these are all correction factors, but there are so many different problems with dynos that you cant really say its accurate. Why do you think you dont full spool until later in the rpm range than you do on the street? Load..Why do you think you dont get as much air, because you arent moving.. Even when they are fine-tuned they are all different between dynos, I know a lot have corrections factors for humidity, air temperature, blah bl, but they are still gonna be off. The only correct way is to to back to back dyno runs and thats only to see what you have gained.
