Stainless Log header Fab

[Mopar318]

I started building the Stainless log today. Will be running a t3/t4 hybrid turbo. Standard t3 flange internal gated .63A/R turbine housing with stage 2 wheel and V-band attachment. Compressor is a 54 trim.

I took a look at some logs people had installed and didnt like how close it was to the intake manifold, so I put a 22 degree angle on the log to keep it away from the manifold. I only have about 80 bucks into it and thats including the flanges.:D

Be interesting to see how it clears the starter and such. Looks good, :thumb:

Nice. This really is a DIY community.

I had the starter stuck on the block where it goes so I could mock up with it on, guess I took it off before I took the pictures. I will weld the flange on more of a upward angle so it will put the turbo to where it is about stock location. The whole header seems to take up about as much room as the stock manifold.

did you port the insides of the "T" pieces where they make the bends. some look nice on the outside but are much less smooth on the inside.

whoa you should make a kit

No porting needed. They where all smooth on the inside.

If I had a horizontal band saw I would. But making the cuts takes a long time with a sawzaw, and I have no way of getting exact cuts so a lot of further fabbing would be neccesary.

[TurbododgePirate]

Hmmmm. Could you make a pair of log manifolds for a smallblock mopar?

[shelbymonster]

where i can find those t ? any link ?

If you were closer we couldn't find anyone to come and pick up our horizontal for free.

[BadAssPerformance]

Looking good... one comment on the "T"s is that they dont always direct the exhaust in the direction you want it to go.

[thefitisgay]

i think it might be the angle of the pic and those ts have no direction

could be wrong tho

[Mopar318]

Yep, the T's dont really direct flow. But I never saw that as much of an issue for a low power, low rpm application. The turbine causes backpressure in the entire exhaust before the turbo.

It would be nice if I had a mock up engine and some more time. I might have mada a equal lenth tubular header in that case.

[Mopar318]

Its getting there. Still waiting on the stainless flange to come in. Need to modify the angles on the flange, I may just do a 5 degree pie cut on the log portion to give more firewall clearance for the turbo.

Im doing a back purged fusion pass, then another pass with filler wire.

Im 95% finished now. Just need to cut the hole for the turbo flange, and weld up the piece. I hope there is enough firewall clearance.....

[Speedeuphoria]

Lookin Good! We still need to meet up sometime

[Mopar318]

Lookin Good! We still need to meet up sometime

Sure, whos is this though?

[Mopar318]

Its done now. Now its off to the machine shop to get the flanges decked flat. 304 stainless sure does like to move when you weld it.

[thefitisgay]

how thick are the flanges?

man im really wanting one of those

[Mopar318]

3/8" thick flanges. Usually I like to use 1/2" but finding them in stainless was going to be trickey. Next time im doing mild steel flanges, and getting the thing coated.

[Tim]

You said the stainless steel likes to move around during the welding process, but what about when the engine is run, and the manifold starts seeing heating and cooling cycles?

If the manifold gasket surface was machined flat after welding, is it possible that after some heating / cooling cycles it would want to warp some more before settling into place, thereby causing the gasket surface to warp some more and putting stress into the manifold because it can't move at the gasket surface end?:confused2:

The engine does not heat the material anywhere near what it reaches when it is welded. It does move around a bit whil the engine is warming, but with the ports being cut after the welding process, then the flange being surfaced, there should be no problem.

[t3rse]

I was thinking the same thing: do it in mild (for a number of reasons) and have it coated

looks good though

[Mopar318]

I have the clutch installed and trans bolted on, and everything together. Here are some pictures for those wondering how everything was going to go together.

Could I mod move this to Fabrication Please? Didnt even know there was a section for that.

[LynX853]

that thing looks freakin sweet! great job on it!

um no, move that log mannifold to my car please. :thumb:

[Mopar318]

Tough decision...but I think it just looks better on MY car!:evil:

[Mopar318]

And with 1/2" firewall clearance to the compressor housing it fits! No BFH to the firewall either. Should have it running in the next couple weeks if all goes well.

[moparzrule]

Looks nice, but you should have used ATP's 3'' V band swingvalve, flows a lot better than that SV you got there!

Oh and get that radiactive orange can off that thing!

[DodgeZ]

damn good job!

[Mopar318]

http://www.atpturbo.com/Merchant2/graphics/00000001/Catalog%20Images/Flanges/Steel/ATP-FLS-067_450.jpg

You mean that one? I dont see how that can flow any better than the piece I have on there. Looking staight into the outlet you can see the flapper. There isnt any restriction.

[moparzrule]

Thats just the flange for it. Your SV kinda comes out the of the turbo and hits a wall and it not directed toward the outlet. The ATP piece funnels the exhaust from the turbine and wastegate both into the V band.

Plus also isn't that SV you have a 2.5'' V band outlet? If you measure the smallest point on that swingvalve all of the exhaust has about a 2'' hole to come out of!

I don't have the greatest pics showing the SV, but...

[Mopar318]

Yes its a 2.5" flange, but the smallest point is around 2.5" not any smaller. I think it will work fine for my setup as is. If I want to upgrade I can just build that same unit ATP sells for about 50 bucks.

I know for sure its going to flow better than the factory setup.

[moparzrule]

No doubt.


Don't forget about the radioactive orange can on the front of your engine :nod:

[moparzrule]

The exducer on a stage 2 turbine wheel is 2.12''...the ID of your swingvalve looks microscopically larger than that 2.12'' exducer in this pic, no where near 2.5''.

[Mopar318]

No doubt.

I put 3 or 4 frams on for diagnosing my oil pressure problem. Mobil 1 filter will be going back on.

[Mopar318]

I though you where talking about the flange. The flange is 2.5". I really dont think the step up directly after the turbine is going to help anything. It not like it steps down after the turbine, it remains the same diamter.

Im sure the ATP piece would flow better, but my current setup what I have should work well. Like I said though, if I need to upgrade I could make that same piece as ATP has for about 50 bucks.

The wastegate exhaust has to come out the same place, and with that SV it comes out and hits a wall and then tries to get out some where, it has no directionality. But even still, like you said, still better than stock :thumb:

[Mopar318]

Yeah, I see what your saying. Hopefully with the large turbine housing, and 22psi boost, the wastegate shouldnt be seeing as much flow through it.:D

I got the downpipe built...well actually modified from the old stainless downpipe I built for the stock swingvalve. Oh what I had to do pie cuts in order to get the radius I wanted. I think it looks cool though.

Theres are 2 nuts to my entire exhaust. I can install it in less than 2 minutes.:D

[Mopar318]

Got the axles in and today the daytona moved under its own power. Runs like ---- thought, needs the ignition timing adjusted, and fuel pressure dialed in.

[sexygomer]

just wanting to know where you got the stainless tubing, i cant find that stuff. looks good man

[OmniLuvr]

so hows the progress coming? im about to fab my header this week, i have a buddy thats going to let me park my omni at his shop while we mock up the header and custom intake. id like to kno what size tubing, thickness and a link where you got all the pieces if possible?

[signsoflife22]

I agree!!! I want one of these too. Man, you may have just started a Turbo MOPAR high performance shop without even knowing it!!!(lol)
