1994 Dodge Throttle Body Dyno
With the throttle body install finished (in all of about 15 minutes), the truck was thrown back onto the dyno at The Dyno Shop. Mark Macneil hooked up a T-fitting inline on one of our vacuum hoses to tell if there was a difference in the amount of vacuum into the engine (Macneil did this for our stock TB as well). If the engine had a little less vacuum, then it would prove that the new throttle body was actually allowing more air to flow into the engine.
