I like the way it looks to just french the runners together instead of using a formal collector. I'd like to see one like this for a 4 cyl or a V6.

Whoa!

Any pictures of the inside?

 

Haven't found any yet, here's a shot of one for a 4 cyl. Apparently this is how HKS does most of they're manifolds, or used to at least.



Fred

 

neukin makes one that merges all 4 together....and the turbo flange is centered to the head flange...not offset like those pictured

 

How would you "french" together a V6? Impossible since the headers are 2 banks of 3. You need some type of intermediate up-pipe that merges the two banks together before the turbo flange. Make sense?

 

I meant for a twin turbo V6 setup, two 3 cylinder manifolds.

this type of collector is used alot in bmw turbo apps.

 

it's alot of welding and cutting too. It looks good but seems like alot of work.

 

ssautochrome?

 

It doesn't look that hard to cut. I could adjust my collector jig to a different angle and cut away.

 

not a chance, look at the far right runner in the very first picture. The cut into that tube goes for more than 8 inches, and it follows the curve of the other tube which is also cut. It isn't a straight line, your jig wouldn't work.

you're right, but i was refering to making a collector out of straight pipe using the same concept instead of bends like that. I have no idea how they would cut something like that.

 

i imagine they cut the tubing on a horizontal band saw

But most importantly, does it work better than a conventional collector?

 

I have the Neukin one in my hands the other day... it looked pretty nice, but the dyno will tell once I tune the car....

probably not a noticeable amount, the velocities probably drop off alot and the turbulence has to be ridiculous. Still looks fancy shmancy
