As someone who deals with copper and lots of other non ferrous metals, in metal on metal seals with lots of (400+psi) for a living, if you have a copper or aluminum washer, thats leaking, just get heat it with a torch until it’s glowing, and then throw it in a bucket of water, and aluminum just heat it till it gets kinda shiny (or take a marker and mark it) and once the marker disappear just let it cool. It’ll soften the washer a ton.
Make sure you can blow thru those banjo fitting bolts. I had some that would not flow air threw them with the barb on it and I believe hunter has ran into the same problem with some of those fitting. But glad you figured out your wastegate situation. 👍
I went straight to a cheap on board air compressor and a 3 port. Very good low boost control plus my air shifted PG is mint. The 3 port will pwm and use air anytime it is in boost but the on board air easily has enough capacity for 1/4 mile pulls and for my shift solenoid. A cheap sensor in my WG dome tells me what I need to know about what’s happening in the dome.
Pretty sure there's cad designs for the 4200 intake flange out there. I know you already have the chunk of aluminum but you could probably send the file out to a laser cutting shop (I use sendcutsend) and have it done for you. Hacking up that aluminum chunk and port matching it doesn't sound like fun.
They are out there. The pre cut flanges are being sold for $300ish. Not sure what a flange would cost to have cut. But I figured this will be cheapest and I'll have to grunt a little bit. Lol.
Man this makes me feel super lucky with my hot side. VSR 7875 and a single 44mm gate. Boost controller turned off only makes 2psi and I hit boost cut (20psi) at like 70% duty. I was afraid one gate that small wouldn't be enough.
All Chinese stuff like atv's that I've dealt with fasteners is the weak point. Makes sense waste gates ect would too. I'm running same one's. I will check them. Ty.
I've had that happen a few times. I normally take the set screws out and red loctite them before running the car
I certainly will now, lol.

I've been considering air. Would be cool for tires and stuff too.

@@BlaserBuilds definitely the cheapest. Nothing a hole saw and burr tool can't handle.
The screws that hold the unit together need loctite as well. I've had those fail as well.
Definitely twin turbo problems I wouldn’t have thought about. The amount of random things that effect the way the cars run is crazy. Nice find.
now its going 6's
In the 330. ❤

4port Mac changed my life.
“Delivery companies really handle your package with care”
I make an advanced table with new combos so I can figure out the duty cycle to boost psi correlation in the shortest time possible.
How is it set up to help? I just have a duty table, dial vs RPM and have multiple values set from 30 to 55 to test.
I’m curious, I have a 4.0# spring in my gate, if you disconnect the reference line it will easily hit 12# or more! I found out by accident 😳😳

Had the same issue last year. set screws backed out.
Had an on3 gate stick hurting my 4.8l went to a summit racing aka black sheep industries piston style and it's been great. They aren't 56 bucks tho..
Good catch on the wastegate. That could have has a bad outcome.
Why not put co2 on it?
No reason. Might do on board air.
👍
My wastegates did the same. One fell out just like yours so I checked the other side and it was loose
