I also just added the map daddy 4 bar map, I hope it works. and I got new front springs 700lb. I will be getting my nascar bars done before the next track day. then the intake manifold build after that track day, I want to see how the car runs with the stock intake mani and this turbo set up before I build one.

Ok so show any filament questions here ya go, its not bolted down but you can see about where it will sit. [IMG][/IMG] [IMG][/IMG] [IMG][/IMG] this bracket will be trimmed off since I dont need the bracket for the internal waste gate anymore. [IMG][/IMG] I know this pic is deceiving but I can reach my hand in between the block and the housing.

You'll definitely need to weld on some bracing on that bad boy.
And these new pictures make it look way different/better. Turbo is definitely not as close to the rail as I thought, so that problem is non existent. Good stuff.

Just looks like it got a little hot. Theres probably a thin layer of crud on top of the weld. After he takes a wire brush to the welds, it will look much nicer. Also notice he weaved the collector instead of a stringer bead.


... still interested in them collector pen shots

Like I said earlier about the tape, I think it caused some contamination, all the welds I used that stuff on look crappy, but yes after you brush them of they look fine, defiantly hot. FYI the collector was not weaved, thats the waste gate tube, I obviously messed up, Defiantly a noob with stainless, aluminum is more my thing I think its 10x easier, this is the first thing I have ever made with stainless.

I was going to make fun of that manifold and question your sexual orientation...but I have pitty for what you've done to those turbo parts and can't bring myself to do it.

Good luck.

Haha, I being no expert in manifold building am very happy with what I have so far, I will run it hard, if it brakes Ill build a better one ( I dont think it will once im done with it), all the while knowing that the turbo, waste gate, tubing and flanges for this whole set up including my flex pipe, exhuast tubing, muffler and down pipe matirials cost me less than $200 even with the welding materials and all of it other than the turbo are brand new. I even made the flanges with some scraps from the metal shop next door and a plasma.

So its been awhile but I wanted to give yall an up date. Its finished and running, I took it out for a spin and if feels like its going to be a lot of fun, It turned my Hoosier's into smoke in 3rd like they where nothing. Now I just need to tune and fix my tach, I installed cops during the build and need to add a resistor I guess. anyways thanks to everyone (except hustler) for the input and help.

Sick!

When do you see positive pressure, and when do you see full boost?

In for vids.
