Back from the dead..... I have been moving to a new house this past month so it has been a while sense I got and "Charger time". I did manage to find time to weld up one header. It is not totally done but I'll finish it up when I weld the waste gate and the seven sensor fittings........
You can see my "poor man's TIG" in the background of the first shot. That is what I'll be using for most of the joints......
I also spent some time cleaning the old turbos up... BTW, I know the paint wont last very long at all, but the stuff is some of the best exhaust paint I have found. It is John Deere "Muffler black" if you care...
That's all for now, I did order a few EGT probes to aid in the placement planing ahead.
I've been busy lately, I acquired a new toy/tool. A logan Lathe
but here is a small update.....
Acc. bracket is in the process of be made..... It's like splitting hairs....
I also got a few wiring/computer components. A HUGE thanks goes out to Jean at JB Performance, these boards are his work...
Basically what you see is three boards, the smallest of which is for two EGT sensor inputes, the other two have 8 more EGT inputs, 3-axis accelerometer, SC card socket, real time clock, optional GPS module, 8 ADC conditioners, 6 high current drivers, 6 low current input/output circuits... :huh: These are just the data acquisition portion of the computer system!
EGT board (small) and the main I/O board using CAN communication...
Main EGT board with all the extra goodies...
That's it for now, I have plans to get a lot accomplished this week end so be on the look out....
Flattening the band saw cut....
Bracket roughed out, alt mounted, and wastegates tacked.
I was unsure how to make sure the waste gates were mounted even and near the same angle, I came up with the string alignment idea.
I've has a few people ask how I'm going to plum my waste gates, I basically am building a miniature header for the gate, keeping each pipe as isolated as possible given the room I have and keep the bank divided to take full advantage of the split scroll turbo housing. I've head many think this is a waste of time and energy but I'm whiling to spend the time....*
Here is the divider, it is thicker the the pipe wall but not by much....
The first pipe of the waste gate header...
Both "main" pipes in, the divider will get centered later.
Here are the "sub" pipes used to allow all cylinders to bleed pressure. The two mains are 1 1/4 the small pipes are 3/4 I think. I can't remember.....
Back on the car, I was going to leave the support on but after some thought I think I'm going to cut it out.
I've started to do the same for the left side waste gate, I'll post those pictures when it I'd complete.*
A little more done. The left side gate is done, so the only thing left for the manifolds is to touch up a few ugly welds, weld in eight EGT probe bosses, weld in two drive pressure fitting bosses, a bit more welding in the merge and a little port clean up. I'm beyond burnt out on the headers, so I'll come back to most of this stuff later........
Here is the progress of the left side...
Connect to holes...
O.K now to move on to the A/C compressor bracket, first, I can not draw well but I wanted something unique. I had planed on a March-ish looking bracket but my wife gave me this idea so I appeased her and drew it up. I ended up liked it enough to try and make it. Turned out O.K imo, but I still have a bit of clean up to it. It also serves as a way to identify what family I belong to if the unthinkable happens, theft deterrent, and more proof I do things the hard/long/waste of time way.......
I plan in building another pivot support for the rear of the A/C pump, the I'll use an adjustable rod to tighten the belt. Never mind the bolt holding the alternator up, it was just used to position the alternator for more brain storming........
