In our last myth busting post, we tested whether or not turning throttle bodies backwards makes any difference in the power and torque. Many people responded to our post asking if we would test this on a restrictor engine.
We ran two tests on our dyno- one with the throttle bodies their normal, front-facing way, and one with them backwards. After a few hours of thoroughly tuning each combination, check out the graph below for the results! Open the image in a new tab for the best clarity.
In this test, the results were about the same as last time- there does not appear to be any benefit to turning the throttle bodies around, even on a restrictor engine. Let us know if there is anything else you would like to see tested!
