A couple more predictions:
Top speed: 144 mph.
It would take about 54 seconds and 1.8 miles to get there.
Which made me wonder what the 1-mile drag race time would be...
Answer: 34.20s @ 138.85 mph

Pickles, was going to PM you a question about your Prodigy turbo, but your PM inbox is full! That in and of itself kind of made me laugh, must be one popular guy. Clean that thing out man so I can PM you!Originally Posted by UselessPickles

Time for another modification to the turbo install!
Here's the wastegate:

It's right behind the radiator fan, a bit below the half-way point of the radiator/fan. Inside the yellow circle is a filtered breather cap, which allows air in/out as the wastegate diaphragm/valve moves. This is the wastegate's atmospheric pressure reference.
Notice all the mud! That's from splashing through some shallow mud (6" deep at most) and some shallow puddles. Clearly, water/mud is able to easily splash up onto the wastegate, and I don't want water/mud getting into the breather port. Especially if I ever end up in water deep enough for the wastegate to get submerged.
So time for a breather hose! I got an extra barbed hose fitting. It's the same fitting used to connect boost/vacuum lines to the wastegate and BOV in the stage 2 kit:

There's not really enough room to simply replace the filtered breather cap with the barbed hose fitting (too close to radiator fan shroud). Luckily, there's an optional breather port on the side of the wastegate. Look back at the first picture, and you'll see the plugged port just to the right of the circled breather.
Here's the plug and filter removed:

You can see that the filter already has some mud in it!
And here's the final result, with the hose fitting on the side, and the plug in the front:

That's 7/32" vacuum hose from a local auto parts store. From there, it meets up with and is zip tied to the radiator fan's wiring:

The end is curved to point downward, tucked behind a radiator fan mount. The end of the hose is at the same level as the turbo itself (and therefore, the air intake), so if I'm ever in water that deep, I have much bigger problems than water in my wastegate.
Doing this with everything already installed was pretty challenging because of the tight spaces. My hands are scraped up. It would be much easier to setup the wastegate this way before installing the turbo kit.
From Prodigy's website, here's a picture of their oil catch can:
It's mounted to the firewall, on the driver side, down low (below the steering shaft).
Their setup has a hose from the engine's PCV valve and a hose from the engine's breather port come together with a tee fitting, then into the catch can. Look carefully and you can see the hose connecting to the can's inlet on the passenger side of the can, down toward the bottom. Another hose runs from the outlet of the catch can (top of can) to the air filter. Then yet another hose runs from the can's drain port (bottom of can) and joins the turbo's oil return line with a tee fitting right at the oil pan.
So this is now a completely closed system, with oil being captured out of the air and returned to the oil pan (instead of sucked into the intake and burned in the engine). Unfortunately, it's no longer a PCV system. It's now just a passive ventilation system.
The catch can kit is currently listed on their website at $389: https://www.prodigyperformance.com/p...2001-pro-2002/
I'll probably order it soon and initially install it as directed by Prodigy. I'm curious to see if part-throttle driveability improves by no longer having oil vapors enter the intake through the PCV hose. Then I'll modify the install a bit to return full PCV functionality, and run only the breather hose through the catch can. If there's no noticeable difference, then I'll keep it setup with the PCV operational. If I notice a difference, then I'll start looking into a dual catch can setup (one for the PCV hose, and one for the breather hose) for a completely ideal, fully functional/closed PCV system with minimal oil vapors getting into the intake.

Would you like a do over on this one too?
Hmm... change of plans. Looks like I could probably put together an ideal dual catch can setup for about the same amount of money as Prodigy's catch can kit. This will be a fun project.
You're gonna fubar your engine..
I can't tell if you're fishing for an argument or what, but adding a catch can setup that maintains PCV isn't going to FUBAR anything.
Did you read his dual catch can idea?
I don't have a problem with the catch can-- I have a problem with his idea for a catch can!
First off the breather hose needs to be free for positive clean airflow into the crankcase. Secondly, what is the can going to do besides possibly impede this ability flow properly??? No, oil vapors come in through the breather hose. Secondly, the catch can doesn't stop the system from being a positive pressure system. It merely instead of dumping the oil, water vapor, unburnt fuel into the intake puts into the in a can then depending emissions standards either vents to the atmosphere or back into the intake just minus much of the aforementioned stuff.
My big diesel engine has a PCV that positively vents right out on the front axle of the truck.
Please explain what's wrong with my dual catch can setup. It's no different than all other dual catch can setups out there for boosted engines, aside from application-specific mounting/routing details.
It is simply returning the PCV system to a fully closed, functioning PCV system like stock (PCV valve connected to the intake manifold, breather port connected to the air filter area). The only difference is that I add a catch can inline on each side of the system.
Yes, oil vapors do come through the breather hose. This happens when on boost. Piston blowby has to go somewhere, and the crankcase breather is the place it goes. I don't want those vapors going back into my intake, coating the inside of my intercooler (making it less efficient) and lowering the effective octane of the fuel while on boost. I also don't want it to vent to atmosphere, because it stinks (that's what it does right now). Catch can is the solution (specifically a catch can with an oil separator in it).
