6-1 collectors?
 

theres been a few how-to's on 3-1 and 4-1 collectors, but does anyone have a how-to on making a 6-1 collector or instrctions/pics on making one? any help would be greatly appreciated. thanks

Re: 6-1 collectors?
 

BMC race made a thread thats probably still on this page about a rb26

check that out

your never gonna find a diy, that 6-1 and any 6-1 for that matter is custom and will never be jigged I doubt

But for reference im sure itd help

I know there was a post on HT's fab section containing a link to a volvo page where a guy built his own manifold and used solidworks to design the collector.

The link was in the first post too. If i find it I'll post it up.

Just gotta figure out the cuts. Just mess around with some stuff like drinking straws or dowels.

ya it shouldnt be bad just practice using some thing else maybe draw it out before...iv also seen 6-3-1 instead of making one huge collector make two collectors exactly the same and then cut them so they both can fit togeather that might help

Re: 6-1 collectors?
 

Also depends on how made-rare you wanna make it.

You can do two 3-1s and then just stack em. 6-1 all in a conical shape would be tougher.

Re: 6-1 collectors?
 

You make it the same damned way, you just cut out 60* per pipe, per end meeting instead of 90*. Jesus christ learn some ------- math kid. 360* in a circle / 6.
Apart from that. Unless there are serious space issues, you shouldn't make a collector with more than 4 ports. You should run a pair of 3-1 collectors. (And yes. That would be 360/3.) Turbulance, and velocity loss becomes high above 4 ports.

I'm sorry, but god damned kids today are ------- retarded...

but is a t3 port a circle? nope.

Re: 6-1 collectors?
 

Ultimately the only thing which will define your collector will be the packaging requirements. 6-3 3-2 2-1 would make for a nice shallow merge, but that don't mean ---- if you can't get it to fit.

Re: 6-1 collectors?
 

but can you make it fit just like a 4-1 if you jigged them at the right angle? yep. Plus, you can push 4 of the round edges in some and pull the side edges out to make it a rectangle, any bit of creativity can solve the alignment problems, even 4-1's still have some over/underhang.

Re: 6-1 collectors?
 

my 4-1 has no overhang.

Not sure how well this works with 6-1 but for a 4-1 you just make a circle and weld just two halves. A large belt sander will take care of the rest. Here's what I mean.

I cant see why this wouldn't work on a 6-1.. would be more work though.
