So its gonna be tight but not too tight? :P

Gotpsi? 12-01-2009 09:37 PM

Yea thats why I made it closer to the engine than the frame, plus I have solid motor mounts so movement will be very minimal.

Collector pen shots??? Also interested in the head flange penetration shots.

Ill get you the pics when Im done, Im not to happy with some of the welds, I tryed some of this weld through tape the welding store gave me to demo, specificaly for back purging and I didnt like the out come, I had some sugaring in a few places. I also had trubble cleaning some of the parts after plasma cutting them, I found that plasma cuases major sugar and you have to grind the heck out of it before you weld to it or your screwed. But hey this is my first manifold and I dont ever do much with stainless so Im quite happy over all with the project so far.

Gotpsi? 12-01-2009 10:01 PM

penatration was awsome by the way, I just had some sugaring, and I think that take stuff cuased some contamiation that I had to grind out and reweld in a couple spots.

SKMetalworks 12-01-2009 10:04 PM

Meh, only tape i use is 3M masking tape; the white stuff. Smells good and does its job. Had 0 sugaring on waynes manifold. Gonna build myself one hopefully this weekend if the damn flanges get here :vash:

Gotpsi? 12-01-2009 10:07 PM

This stuff was aluminum foil like, It has adhesive on two sides and nothing in the middle, so you are supose to just "weld through" it but it did some strange things so I just diched it.

Gotpsi? 12-01-2009 10:07 PM

It worked great for blocking off the flanges though!

"If it aint broke dont fix it"

The stuff was free and it was suppose to help so I figured Id try it.

O and by the way my wife is the best! look what she made me while watching Shrek 3! Attachment 202069
now it just needs some nice loom so make it look organized, and I need to make a hold down bracket. FYI its all soldered and heat shrunk, no but connectors.

HAHA that's great:)

What are you going to do about the ewg sitting so high up and hitting the hood?
Also that turbine flange looks like its directly over the rail: looks like it will be a SUPER tight fit for the turbo.
And how are you planning to route the wg tube? Looks like the manifold blocks off its passageway to the dp

Braineack 12-04-2009 03:46 PM

i have a feeling you're going to have boost control issues.

Gotpsi? 12-04-2009 03:50 PM

the waste gate has plenty of clearance thats what the second pic is. Ill get some pics of the turbo on the mani soon, the turbine housing was still hot when I took the pic from welding up the internal waste gate hole. and I have not welded the 90 on the compressor housing yet that it will have. The hardest thing will be the the wastgate routing to the down pipe. it must go behind the manifold by the dip stick.

18psi 12-04-2009 03:55 PM

That's also where the heater core hoses are. Did you remove yours altogether or just for now? If you have your wg tube right next to em they will melt fast

wayne_curr 12-04-2009 03:58 PM

In for 6" wastegate dump out the hood.

Gotpsi? 12-04-2009 03:59 PM

I dont have anything in my car its completely gutted. The only thing it will be close to it the throttle cable. I already melted that so Ill have so Ill have to make a heat shield.

I was actually considering doing it.

18psi 12-04-2009 04:00 PM

Oh, I somehow missed that this is a gutted track car. In that case go nuts and vent straight out the hood:D
