The last runner was finally welded to the collector!

Welding the last runner to the collector was a bit tough! Still managed to achieve 100% penetration though!
Image

I have some 3/4" 6061 AL plate that's gonna get drilled and tapped so the head flange can be bolted down before welding the runners. That's on the to-do list along with punching a couple of holes in the collector for the wastegates.

I'm so ready to move on to other ****! Lol

i know the feeling....

i envy your seat time and experience for tig, how long have you been doing this?

looks solid

imo i would consider going heavier for your plate to stop the flng from warping

ive seen some stainless flanges pull pretty bad on marine stuff.

beautiful cratsmanship none the less

I've been doing tig for roughly 3-3.5yrs? That includes school. It would've been longer if it wasn't for the **** economy :roll:

The flanges are hot rold steel. They won't pull as much as SS, but I've seen how bad they can get if welded without being bolted down lol...

If you can. Just torque it to a KA head. SS can warp pretty gnarly if it's not welded correctly.

Mild steel can still warp just as bad. Just allow for lots of cooling time.

I feel your pain with the economy. I've been welding 8-9 years. Went to college for welding 3-4 years ago. Graduated 2 months before the recession.
Now I'm so sick of it I'm back in school doing something completely unrelated to the industry.

I'll be signing up for a welding class locally in hopes of one day building something half as nasty as this beast you've brought into this world. I'll never run a T4 on my engine and I'm still jealous of this manifold. One day...

Time to start hanging with all of the old skool fabricators and welders in my area. I'm bound to find someone willing to show me some tricks that will help me out.

We make a lot of our jet engine parts out Inco 625, not that common on cars, but if I had a "nickel"....haha

whatever lame joke,... I know.

You shoulda went baller and went Inco 718 or straight Waspalloy or MP159.

Originally 718 was going to be used, but 625 is stronger and rated for higher temps.

Alright, picture time! I'll be picking up (kinda) where I left off

Holes for WG ready
Image

FFwd to now, manifold is fully welded
Image

FWD and AFT WG Dumptubes. They are 2.000dia x .035wall 321 Stainless.
Image

Downpipe, still work in progress... 4.000dia x .028wall Inconel 625.
Transition is spun Inconel 625, 3" to 4" dia, .035 wall nominal
Image

Weld on SS Vibrant Vband flange to transition, Inconel 625 filler rod
Image

Penetration
Image

As you can see by the following pics, even without AC and PS it get crowded fairly quick :shock:
Image
Image
Image
Image

That's where the project currently stands. The downpipe will be made to follow the contour of the firewall, under the car it will get SS vbands throughout and after the flex bellows the material will switch to 321 stainless 4.000dia x .028wall tubing for the rest of the exhaust system.

FACK I still have a lot of work ahead of me lol :x

Awesome job. That setup is gorgeous. Are you going to make an intake as well?

yes and no, 625 is a bit more ductile, but 718 has a higher ultimate strength, but 625 can handle thermal stresses much better. They are both rated for ~1200 deg F continuous operation, we use them pretty much interchangeably on our stuff...if the structural analysis shows the part failing to meet full life, a material swap to 718 usually fixes the issue - and adds a ton of weight.



- but either way the set up looks pretty impressive, when Im done with my SC build def want to go a similar route.

I did some research on their properties, from what I gathered Inc625 seemed like the best choice for this application. I believe I saw somewhere that 625 would take 1600*F no problem compared to 718 only being good to 1300*F. Also 625 is easily welded to dissimilar metals, 718 I was unsure about and couldn't find anything to confirm that it could be.

I too think either would have been fine, its only gonna be a street/strip beast running on e85 not a JSF F-35 :lol:

That's the plan. I haven't sat down and designed anything yet although I do have some ideas floating in my mind. I was told if I designed parts using CATIA V5, like the intake mani head flange for example, we can get them machined in house 8)

agree'd, as soon as read that you were using inco for the DP, I was like, "oh a proper build."

I've been helping with some design work on the Lightning, and EVERYTHING is inco....the tubes, the brackets, the bolts...its actually pretty awesome.

This setup looks awesome, very nice manifold. My only concern is the very tight tolerances between the piping and the strut tower / steering shaft, might cause issues when the motor torques. But it is hard to get a good idea from just the pictures.
