My first 12v manifold build

[nastyhooker91]

It's much cheaper than buying one. I only paid $5/elbow and then bought the flanges.

Where are you buying your fittings from?

holy chit!!!!!

They are 304ss t4 twin scroll merge collectors. Setup for single 44mm or 60mm gate or say dual 38mm gates. Runners are sized to cover up to 1500hp at the crank. If more was needed i think the size would need to be slightly larger but this is my opinion. Working on head flange design at the moment. Then back to having some t6 and tial vband versions done.

How much do those cost?!?

Im not selling them unless someone wants the rest of the manifold with it or you make me a good offer lol. Most of the problems with manifolds are at the collector this should take care of that.

Got the head flanges finally done so I tacked up my tow twins. I need to make a jig up and then weld it together.

Didnt realize the pics are upside down. Fixed them and added a few more. This is going on my 02 vp44. No reason to run any bigger when i dont have the fuel to even push this setup. But will be great for what the truck is used for.

304ss head flanges 3dmachined match pipe to port
304ss billet merge collector
304ss pipe
Hx35 non gated
S366/73/1.25 t4
tial mvr gate

^^^That deserves a thread all its own.

 

[kjpcummins]

I think im going to put a jig together for a header that will put secondary down in the 3rd location and primary up top and forward. Since i have another one of those s366 turbos sitting here.

weight

Hey fellas. My hats off to every one of you who are fab'n those beautiful manifolds.

Has anyone weighed the end product v/s say a steed and v/s stock manifold? It might sound silly to some, but, every ounce counts.

Also, I would be very interested in purchasing a t-4 flange version from anyone of you fellas. The style like the Ghostman is fabbing would better suit my space confinements, however.

We can fab and do pretty much anything, but, I doubt I'll ever reach the quality level I'm seeing here and the time to perform the work is getting very scarce.

That looks great! Would you consider selling the custom oil filter?

I can put you in touch with owner of said oil filter lol. I borrowed the engine for mock up.

Awesome work man. I'm in the process of getting flanges made to build another, I have other ideas I want to try out.

The 2nd gen style manifold i built this weekend weighs 11lbs. That is with sch 10 1.5 304ss pipe and 1/2 304ss flanges.

The 3rd stock manifold i have weighs 17lbs.

The header i built above weighs 22lbs. But it would weigh less if setup in normal turbo position as it would use a bit less pipe and closer to the weigh of the stock manifold.

Many unique projects have space issue but is that because your limited by putting the turbos in the stock position. The benifit of a fabbed manifold is your possiblities are only limited by your imagination.

FYI, my manifold warped pretty good, bent up and twisted itself. I took my time welding it slowly in stages to try to prevent that. I might should have bolted it down, not sure if that would have helped. I bought a 1/2" flange and maybe should have gotten a 3/4" flange. After trying to mill it flat there isn't a lot left on the flange.

 

[kjpcummins]

Bolt flanges to a piece of 1inch thick steel or 1.5-2inch thick aluminum when welding. Unbolt them when they fully cool down. That will help them stay straight.

Looks like a RMS collector?

 

[kjpcummins]

Nope these were made quite some time before rms made their first one.
