This week our dyno arrived and we are pumped to set it up this week. Currently we are tuning with it and doing baselines as well with our current builds. As far as the setup, I mean calibrating the dyno to how we feel it should read based on our experience with previous dyno's we have owned and also rented.
Each dyno company calculates RWHP differently, so configuring the test pulls that are accurate for tuning purposes for us to tune and also the runs that read the numbers will vary pull to pull. There seems to be rumors of how "Hub" Dynos read higher, which in fact with this particular dyno with how we have configured it, reads lower than most chassis dynos. There is no certain percentage a dyno can be higher or lower since those variances will change based on which load test is being performed, environmental factors such as weather and density altitude, and also each operators calculations. Every dyno can vary in hp/tq numbers depending on how they are calibrated and the amount of load it is given. This is also based on eddy brake dynos, and weighted roller dynos.
Simply put, a dyno is a tuning tool. It's a tool that simulates real world tuning but it also measures HP. If you were thinking a hub dyno will show you higher dyno numbers, this is probably not the dyno you want to read your numbers. If you are looking for an accurate tuning device to get your car dialed in, then this is the place for you. Be sure to schedule with us for more accurate tuning!
