Header flanges for US Crossflow owners

Post #1 by '68falconohio » Mon Jul 05, 2010 12:13 am

Alright guys, I just finished up a model in Solid Works for the crossflow.
I have a source with a CNC Hi-Def Plasma table and I'm going to see how it comes out on 3/8" mild steel plate. I don't believe that his table will do a good job on 1/2" plate as plasma cutting leaves a taper that's more prevalent as the matl. thickness gets larger than the hole diameter.

I'm going to try one on 1/2" though for those wanting to turbo. If the 1/2" plate can't be fully cut on the table maybe I'll have him cut the flange profile and port holes, leaving the boltholes to be drilled on the drill press with a 3/8" plate as a jig?

I know of one FSP member who's interested in header flanges but is anyone else interested?

Once I confirm fitment on my head, I'll post some pics. I'll have pricing then; they should be quite affordable.

1/2" is kind of thick, even for a turbo application. 3/8" would be plenty, I think, and 5/16" would be sufficient for most other N/A uses.

It seems the consensus on theturboforums.com is that 1/2" is a good thickness for turbo flanges; that's where my thought came from. I do not have any experience with turbo motors, just offering up this group buy on flanges because I have a good contact with a CNC cutting table. I'm going with 3/8" thickness on my N/A setup so that I can hit the flange on the belt sander to true it up after welding. Hopefully I have some pics of a good fitting flange by the end of the week.

Don't get me wrong - 1/2" will work, but welding a 14 gauge or 16 gauge tube to a flange that thick will be tricky. That much metal takes a lot of heat to get any penetration. It'll take a good TIG operator to keep the heat directed to the right place. Other than that, I think it's just thicker than it needs to be.

10mm is the norm down here, and I wouldnt tig weld either, the MIG is better for that, TIG is OK for the other pipe welds if you really must have a speccie job.
I always laser cut my flanges unless they are thicker than 20mm which is the thickest that can be cut with that process, (less in ally) thicker is water jet.

10mm is closer to 3/8". I would think a MIG on such dissimilar masses of metal would be even harder to do.

MustangSix, it's my understanding that most DIY turbo header builds are done using sched. 40 weld elbows and sched. 40 pipe due to the temperature and stress. 14 and 16 gauge mild steel won't live long w/out mucho bracing, AFAIU. If this isn't accurate, someone please let me know.


MIG will shine with dissimilar material thicknesses; torch angle and parameters adjusted accordingly.

If you're welding 1/16" material to 1/2" though, once fusion on the leg of the weld is greater than the thinner material's thickness failure is forced into the base material. To qualify a welder for Sheet Metal welding to AWS standards, they have to weld the sheet metal to a 1/2" plate in a T-joint configuration. By far one of the easiest tests because it's super easy to get 1/16" of fusion on the sheet metal and force the failure into the sheet metal.

I'll be TIG'ing mine.

Still havn't had a chance to drop by my buddy with the plasma table, hopefully tomorrow.

Never built a turbo header, so you may be right about the Schedule 40. I think this is an area where my welding skills fail me. :(

I'm hoping this thread will "grow" with some photos in progress of welding pipe to flange.

As someone with negligible welding skills, the more I understand what someone is supposed to be doing for me - the better!

like I said before I would be down for a couple sets (4-6 prob) 3/8 is fine even for a turbo.

My contact will be at Lake Cumberland on vacation next week and I didn't get a chance to talk to him this week(work in the way). Sometime the following week(Aug 2nd) I should get a day off of work.

The plan is to burn a test plate in some 16 gauge and check fitment on my head, tweak the .dxf, then get the real thickness cut. Once the .dxf is verified it should move quickly.

I don't want to put my foot in my mouth on the price, so I won't throw a dollar amount out yet. Will let all know when I get a fixed price from my cutter. Sorry for delay.

Guys, I lost my .dxf..... when I quit my job. Since it was saved on the company jumpdrive I carried around I can't get it back. Worst yet, I used a milling machine with a dead center chucked up to plot each center point of the mounting holes and ports(worked great!, DRO's rock) but I brilliantly wrote everything down in my composition book which they now have. I'm still trying to get the .dxf back or at least all the centerpoints so I can remodel it. :bang: :bang: :bang:

Here is a one flange I made for my 223 turbo header, but the 3 & 4 exh port need a divider. So I made another one. its 1/2" mild steel with sch.10 runners.

Some tIG welding and grinding.

This is a long term project so I have not got it out on the road, but it sounds awsome.

OK, I learned my lesson on posting something before I had it ready, but here's a test piece. I burnt this out of 3/16" CS to confirm hole location and fitment to the head. The port holes are 1.530"(good to slip 1.5" tubing through) and the bolt holes are .410-.420". There will be a little bit of taper to the bolt holes when cut in 3/8" but I will ream them with a .420" bit before they ship. The flanges will be 3/8" CS, I will check on SS if anyone is interested. I will have more pics of finished flanges soon, along with a price per flange. I'm going to move two of the bolt holes .010-.020". The test piece bolted up fine, but they'll be better if I move 'em just a smidge.

The top strip is something we added to help keep the flanges from moving while welding. I can zip these off with a cut-off wheel if you do not want them, but I plan to take advantage of them and leave them there when I make my headers. The tabs that connect them are only about an 1/8" wide. Even though the top strip is there, I would still attach the flange to the head or another suitable working fixture when welding/fitting the headers.

Also, I have a .dxf now for the intake side. I havn't done anything yet to confirm its fitment or set a dimension for the diameter of the port holes yet. But if folks are interested, we can get a batch of them cut too. (This willl take me a little time, I'm very busy with school right now)

A BIG thanks to CNC-Dude for helping me get the flanges re-drawn. After I lost the initial drawing, he was a big help in getting the flange re-drafted. :thumbup:

Stephen, I just hated to see you being so close to having something with that much potential, and then having your files lost like that. Im glad I was able to give you a hand to get back to this point! I hope they do well for you. Thanks.

Two things to consider when purchasing from OZ, shipping cost and exchange rate.

1. Shipping could cost as much as the purchase price.

2. Exchange rate between Australia and the US favors the Aussies now:
What use to be $1.00US=$1.20AU is now $1.00US=$0.98AU.

I just got a 250 crossflow and would be interested in a header flange. Are you using hot roll or cold roll steel. Will it have enough meat around port holes to enlarge? Are you concidering a intake flange? The injection set up on my engine may not clear the hood and I might have to make my own intake.

The mild steel I'm using is Hot Rolled, Pickled and Oiled. Stainless steel(304SS) is also an option if anyone wants it. I know you guys want to know a price per flange and I do too... I'm still waiting on the cutting house to give me a price per piece. I have a meeting with them tomorrow to discuss other work(employment), they should have it for me then. Once they give me a price, I'll give everyone a little bit of time to decide whether or not they want a flange and how many before I get a batch cut. I intend to cut 2-3 extras for crossflow guys that come about in the future. They are swamped right now with work but promised to work me in.

Intakes are definitely an option if anyone is interested. What I need from the folks wanting intake flanges are:

1) A rubbing or drawing for the injector scallops(dimension and location reqd). The head that CNC-Dude cnc'd for me was a carby head; there were no scallops and I don't own an EFI head to look at/check fitment with. If anyone has .dxf of the EFI head that they're willing to donate to the cause that would be just as good, if not better. I'd like someone with an EFI head to confirm that the flange I cut fits the head properly before I cut a batch. Rather than make everyone port the flange a bit to make it right, I'd rather it lined up correctly from the go. (XFlow', PM me if you can do the rubbing and I'll give you an addy to mail it to.)

2) What diameter do you want the port hole to be? I havn't had the time to check what standard tubing size is offered/what would be best. I would prefer to make the flange suit a non-ported head and the end-user would be required to port it for larger sized tubing if porting has been done. I think that makes the most sense for everyone.

3) Spec carby or EFI. I doubt the Carby guys want the scallops cut out in the flange and vice versa.

6cylfever, how much meat do you need around the port? Intake and exhaust? I don't have the revised .dxf in front of me right now or the sample flange we cut. The cutting house has my crossflow head and the demo flange. Some punk has my laptop that was stolen a few weeks ago with the majority of my work on it so I can't check. IIRC, there's at least 3/8" addl. radius around the ports, if not more. I will check on that and report back, if more is needed to satisfy everyone's setup it can be done, I just gotta know what everyone needs.

School isn't taking up any of my time anymore so I have a lot of free time right now...I may be leaving for some pipeline work soon though.

What vehicle are you planning on installing the crossflow in? If it's a Mustang, you shouldn't have any problem. MustangSix installed one in his 66 and had hood clearance to spare.

Are you concidering a intake flange? The injection set up on my engine may not clear the hood and I might have to make my own intake.

What size header are you considering. I looked back at my original file drawing, and these flanges can easily accomodate up to 1-5/8" tubing if you need to go that large. If you need larger than that, I can modify the drawing to fit whatever size you need, and give it to Stephen so he can cut them for you.

'68falconohio wrote:The mild steel I'm using is Hot Rolled, Pickled and Oiled. Stainless steel(304SS) is also an option if anyone wants it. I know you guys want to know a price per flange and I do too... I'm still waiting on the cutting house to give me a price per piece. I have a meeting with them tomorrow to discuss other work(employment), they should have it for me then. Once they give me a price, I'll give everyone a little bit of time to decide whether or not they want a flange and how many before I get a batch cut. I intend to cut 2-3 extras for crossflow guys that come about in the future. They are swamped right now with work but promised to work me in.

Intakes are definitely an option if anyone is interested. What I need from the folks wanting intake flanges are:

1) A rubbing or drawing for the injector scallops(dimension and location reqd). The head that CNC-Dude cnc'd for me was a carby head; there were no scallops and I don't own an EFI head to look at/check fitment with. If anyone has .dxf of the EFI head that they're willing to donate to the cause that would be just as good, if not better. I'd like someone with an EFI head to confirm that the flange I cut fits the head properly before I cut a batch. Rather than make everyone port the flange a bit to make it right, I'd rather it lined up correctly from the go. (XFlow', PM me if you can do the rubbing and I'll give you an addy to mail it to.)

2) What diameter do you want the port hole to be? I havn't had the time to check what standard tubing size is offered/what would be best. I would prefer to make the flange suit a non-ported head and the end-user would be required to port it for larger sized tubing if porting has been done. I think that makes the most sense for everyone.

3) Spec carby or EFI. I doubt the Carby guys want the scallops cut out in the flange and vice versa.

6cylfever, how much meat do you need around the port? Intake and exhaust? I don't have the revised .dxf in front of me right now or the sample flange we cut. The cutting house has my crossflow head and the demo flange. Some punk has my laptop that was stolen a few weeks ago with the majority of my work on it so I can't check. IIRC, there's at least 3/8" addl. radius around the ports, if not more. I will check on that and report back, if more is needed to satisfy everyone's setup it can be done, I just gotta know what everyone needs.

School isn't taking up any of my time anymore so I have a lot of free time right now...I may be leaving for some pipeline work soon though.

Stephen I haven't torn down my engine yet. The exhaust ports don't look very big. I see your from Ohio, I'm asnowbird in AZ right now but will be back in Mich in two weeks. I'll tear down the engine there and get back with you than Marv

any update on when these will be available?

Any chance for making some for a 1-5/8" tube?

found a local driveline shop that builds rides on the side. I dropped off my V8 S10 driveshaft to get shortened and will be talking to them when I pick it up to see if they cna cut me some SS 3/8" flanges for my header. I am going to have them cut for 1-5/8" tube (minor opening up will be needed for weld el's) I have a lead on a shop in Nashville that can do them but will be a little costly since I don't have a CAD file of these (no CAD at work....go figure) I am hoping to have something lined out by the end of the month on these.

I will update when I find someone who can supply these and with pricing. When I do have some cut I will mostly likely have an initial run done of half a dozen sets.

I got pricing in the neighborhood of $60.00 each for the 3/8" mild steel header flanges I drew up for Stephen for this Crossflow project. That was laser cut instead of plasma. Plasma sorta' introduces issues that aren't present with laser cutting making plasma a little less desireable as an option for use in this application IMHO. I also have intake flanges drawn and can make them available if anyone is interested in making their own custom intake manifold for about the same price.

I know this post is old now, but wondering if anyone ended up producing the crossflow exhaust flanges?

Thanks,
Tim

I'd be interested if its cost effective to run just one or two flanges.

I'll see if I can find my CAD file. It's been over 10 years since this thread was started. Thanks!

This crazy I was just on ebay for Australia looking at headers(extractors). Before ordering I will wait see what happens with the flanges.

Yes it was me . I was really hoping to buy it in the USA. I was looking and can not decide what to do. I was looking at kits to make one and it seams like the kits are about as expensive as buying one made. Sorry for being sure of what I want to do.

Ok, I found my X-Flow Header flange file. So I want to know who all can seriously commit to purchasing one? They will be in the $60-ish range plus $9.99 shipping. I may require a small, non refundable deposit from those interested due to several non responders from other custom parts requested in the past that never followed through with their purchases after I had considerable investment in material and labor.

Thanks, Scott

Thank you! I'll let this go on for a week or so for others to chime in and decide.

Thanks
