Yeah, this is a bit of a stretch for a punny title, but it was either this or a few different riffs off “dump tube,” and we’re just too classy for that. Maybe.
Once again, we return to the current idol being given its due worship over in fabrication, Perry’s 190E. Before we dig into the bigger stuff, let’s tackle one small thing first. With the addition of the Cosworth intake manifold, the 190 lost one very important piece — something to hold the throttle cable in place. Without a clip or holder of some sort, the cable just flaps around loosely in the engine bay. Obviously this isn’t going to be overlooked in any build, so we went about fabricating a workaround. Using the mounting point off the strut bar, we made a small tube that holds the cable in place without being overly complicated:
And now it’s on to the big fish. When you last checked in on our welding, we finished all the runners of the turbo manifold and had everything mounted in place. At that point, one of you may have been wondering, “Hey, Fluid, where’s the external wastegate going to go?” Good question, person-we-just-made-up. The external wastegate, which we recently painted black along with several other aluminum pieces in the engine bay…
…Will be connected at the merge point in the manifold, just before the manifold bolts to the turbo. After a bit of cutting and some good ol’ fashioned backpurged TIG welding, we had the wastegate and its corresponding dump tube assembled and mounted in the proper space, with the dump tube pointing straight downward after a bit of a curve (to make way for the downpipe):
Speaking of downpipes, we also made one of those. And yes, only one. Two would have been overkill; as a matter of fact, it would have been twice as many downpipes as we needed.
With that in place, connecting to the exhaust that came along with the 190 when it first arrived at the shop, all exhaust-related work with the 190 is complete. That’s not saying it’s done yet — we’re currently working on the catch can, among other modifications and necessities for a properly running motor. So stay tuned!
