Ya, WE KNOW..... Wastegate placement is FAR less important than extrude honing to clean up shitty internal fitment....:X. Your position on the subject is not even worth hearing due to the statement alone. Creep.

Get it???

I made a funny boy.......

On the note of shitty wastegate placement... I have seen cars where even without a wastegate bolted up, the car was able to make boost on the dyno with similar placement to that gate.

foghorn leghorn owns!
and speaking of layout -----ups. Never have a 5+ merge collector, and especially combine that with shitty wastegate placement

lawls!

Re: collectors, lets see yours,ect
 

Agreed on the wastegate port- I'm not sure how that is going to pan out. A LOT of factors come into play with respect to wastegate function (or lack thereof LOL) so we'll see.
My 60mm wastegate should show up monday- if the flanges allow I might replace the (1.5" sched 10) pipe with a piece one size larger...moving it will be a last resort. :-X

Absolutely nothing wrong with 6 into 1 though. It's been done hundreds of times and will continue to be. If the pulses have a reasonable path and the primary entries are
relatively on-axis relative to the turbine housing, there is not reason not to- packaging/engine bay layout dictates this as much as anything.

On the other hand, when I modify it for the twin scroll T4 housing, it'll technically be two 3-into-1 housings. :D ;D


You could argue collector volume gets large but I think it is marginal in most cases.

Cool that you are cutting your own flanges. O0

Cleaning the pipe a little more before you weld it will save time in the long run- it will weld niver. Clean is everything.

In the top right of your last pic, you can see where the weld is contaminated/porous. All of that black crap on the pipe is trying to float right into your welds.

Otherwise, good on ya!

Also, checked out that link where the guy has the scary jig for doing collectors on the chop saw. I think i will pass- I have seen a 16" chopsaw disc explode, tempting those suckers is not a good idea IMO. Nice way to seperate your kneecap form the rets of your leg. ;D

Bandsaw Owns.

Re: collectors, lets see yours,ect
 

A 6 you have excessively reduced the velocity in the collector for no reason.
Where a 4-2-1 turbo manifold sucks to a 4-1, a 6-2-1, is best 6-3-1 still much better than a 6-1

Re: collectors, lets see yours,ect
 

Agreed on the velocity- that's what I was alluding to when i mentioned collector volume.

On a T3 turbine housing though i think it's really moot.

The more important question is why a ------' T3 on a 6 cylinder. :l Yea, I dunno...

Hence the re-work. I suspect it will be more like a 6-2-1, i'll end up building a pair of 3-into-1 collectors that are welded to the pulse-paired t4 manifold and try to create some sort of proper merge.

Space is horribly tight though.... inner fender sledgehammering may be in order. >:D

Re: collectors, lets see yours,ect
 

Or keep the T3 and swap a 1.06 A/R housing on it. Have it clipped if you must.
I had good results at 6250rpm on a toy v6 using a t3 .84 / t04e 60 one time.

If it's a full t3, they can make 350 on your typical 6 cylinder if you really want them too. More cylinders and displacement makes life easier than your normal i4 guys have it. Also alot less stress per cylinder part for the sme power.
