Megan Header Dyno Results - Toyota Yaris Forums

ChinoCharles · 01-10-2007, 01:20 PM

I will definitely be going back to the dyno to retest the header. Right now my car is stock, as I have the header off to save me some work when I do go back. If the pulley is delivered before the dyno is fixed, I will be testing that too.

Since the dyno was just reading heavy, I am looking at the graphs now and thinking that if you reduce the numbers by about 25% it should be somewhat accurate. Knowing that, the header does so little on its own that I don't see much of a point in testing the car with the stock header and pulley. Whatever the pulley does with the Megan header on is going to be on par with what it does with the stock header, and that saves me having to put the car on the lift twice.
