PlumCrazy's 88 SuperCab 2.3T Build

[PlumCrazy]

Double checked my wastegate plumbing and all is well. Picked up a hand held vacuum/pressure pump that is actually pretty slick.

From what I can see so far...I had maybe a little too much preload (5-6mm) and the rod configuration had the actuator in a slight bind that seemed to not allow any movement until about 12psi and not fully open until 20 psi. My next fear is that even after I optimize the rod preload and routing....that this wastegate may just be inadequate. It only opens 3/8" and its only a 1" hole or so. I have read people port the hole for more flow, so that may be something I look into.

Wastegate actuator test video

I got it to a point where it has visual movement at 9psi and full open by 15psi which seams high still after confirming with the place I purchased it that it is supposed to be a 7psi actuator. I also tested a few factory actuators and they seem to be similar though. so maybe the Harbor Freight gauge isn't accurate? The company also volunteered another actuator to play with and it should be here tomorrow. Hopefully it comes with new snap ring too.....becuase I sent mine into orbit when it slipped off and was not able to confirm re-entry.

I was able to drive the truck a bit today. Put about 75 miles on it over all.

Boost control is manageable now. If I roll into with some sense it will maintain at 13-14psi. If I let loose and flat foot it...it will head to 20. I set the boost safety to 15ish and have only hit it a time or two.

Valve cover leak went from bad, to good after snugging up the bolts....then to not ideal... Now leaking at the front with tight bolts.

So catch can is probably in the future after resealing the valve cover.

Looks cool at least.

A self draining catch can with atmospheric vent would work pretty good, it's been on my list of things to make as everything available aftermarket is manual drain and I'm too lazy for that...

I'm probably doing something wrong... I can get to the page with a pic of the video. Even goes full size with a start button in the center, but nothing happens.

Did you actually see the video? I waited about 2 minutes and nothing. When I pull up the "info" I get the following, which to me means it's just a picture....

They work for me, but they are shared from my drive. I could upload to YouTube I suppose.

Decided I should probably figure out some sort of filter and a blow-off valve after raw dogging around for 250 miles...

Scooped up well used TurboXS blow off and little bit of 1.25" stainless tube on ebay

Made a bung out of the tube and TIGd it on

Got a 135* boot and a some left over stainless pipe and it all kinda fell together pretty easy. FYI a lot of K&N filters are clearance prices on Advance Autos website.

I trimmed back the boot using some scrape tube as a guide

Mocked up an airbox/heat shield shape with a bit of filler wire

Upcycled some aluminum

Just need to get some clamps for the boot and probably weld a support tab onto the pipe to hold the filter up off of the head shield

Got a little mixed up on my cut lines/vs bend lines and cut 2" too much off on the important side...so I compromised and just bent a 45* angle to get as much height back as I could, but I may redo this whole setup differently some day. Ideally I should move the battery to the driver side and make an air box that can pull cool air around the headlight or potentially go back to a stock style airbox with a duct up to the rad support again.
