So, this story began almost ten years ago, when Ron Hatton, was on one of his road trips. He was with Aaron Cheek, another Gadgetman, and was demonstrating the modification of the throttle plate edge. I've given it the name Power Edge. In this youtube video, he demonstrates what it is, how he did it, what tools, and the reasons for and results from it. He tells it all here:
After watching the video, it should make sense. I got re-clued in about this mod last summer by a customer who did it himself on his own TB. And, it worked!. So, I started doing it myself too .I've shaped quite a few throttle plates since last summer, in combination with the Groove, for all customers. Every feedback I've received since I began this extra mod, has been excellent, save one, whose engine needs more attention because of old vacuum hoses.
A few results I've received back so far, include: 25%+ mileage increase on a 2016 Toyota Tacoma, 33 MPG observed at 45 MPH, on a 2012 Chevy Silverado 5.3L 4x4 truck, and nice power increases on both a 2013 and a 2021 Honda Ridgeline V6 engines.
So here's a few photos of what this looks like on various TB's:
I hope you caught Ron's mention of NASCAR's use of this great mod!
Great photos...
just take care when applying this technique so that you don't cut into the diameter of the plate, or it'll cause idle issues - issues just as serious as a manifold vacuum leak
Those are some shiny throttle butterfly plates!
