  • When doing a show like this it’s always a good idea to put on all the welding PPE. Gloves and sleeves are always recommend when welding. It not only protects you from sparks and hot metal but also the light given off from the welding process will damage your skin to the point of possible skin cancer. Please put on PPE so people watching don’t pic up bad habits. P.s. love this show otherwise!

  • Leave the cat on, put an electric exhaust dump before the cat controlled by the boost controller. So when you mall crawling you don't have to deal with the smell, and you bypass the cat, muffler and 10' of pipe when its time to go.

  • Your mig gun cable should be kept as straight as possible to prevent bird nest. And you didn’t wear a jacket which is not good as mig welding produces several different lights, infrared, ultraviolet, and there’s another I can’t think of and it produces radiation, not wearing proper ppe is rather reckless.

  • Ah, the good old test pipe. Something I've done on nearly every Honda I've ever owned, much to my neighbor's dismay. I eventually got smart and just did header back exhausts but before I had money, cat deletes with a ghetto ass test pipe rigged in it's place was the ticket baby. Who cares if it made more power, it sounded like it did and that's all that mattered to 19yr old me.

  • Grind the wastegate hole. This was always a common mod for Mitsubishi turbos with internal wastegates. The flapper is plenty big enough to cover a larger hole, but the wastegate hole itself wasn't big enough to bypass enough exhaust gas, hence it goes through the turbine itself, increasing your boost. Shouldn't take more than a couple hours or so to pull the turbine housing off and grind that sucker. I saw you were making about 235 and I guessed you'd make at least 250 with the cat bypass. Cat bypasses are no joke. If you're trying to make power at the track, a cat bypass is a no-brainer. PS- I love all of Zach's content. He's great, and he's taught me a lot. Dude knows what the hell he's doing!
