Default Could use some help on another thread about manifolds.

Ok so check this thread out, a vendor on there is making some pretty rediculous claims, stuff like "a manifold shouldn't flow good so that it creates more pressure to spool the turbo" and other rediculous stuff. Needless to say we are in an argument about manifold design and stuff, and because this guy sells injectors and all the diesel guys who bought injectors from him are now in bed with him they believe his rediculous theories on turbos and flow. So if anyone would care to help out and shed some knowledge on that forum I would appreciate it. And yes I am embarassed to be a member on that forum

Yep theres a lot of pages of BS now.

what did you expect from a bunch of diesal VW owners.... VW's are crap......

your flanges look nice, although i dont agree with your exh mani design. i think it need to be more simple. it would be a pita to try and mass produce a manifold like the protptype you have pictured. alot of welding and small precise cuts, that **** takes up time ..... and we all know time=$

Yeah vw's can be pretty lame at times, the owners twice as bad What exactly is a more simple manifold gonna benefit me for? Poorer performance? Yes these manifolds arent the easiest to produce but I can throw them together suprisingly quick, and because I am using weld el's I actually don't make more than 5 cuts a manifold.

you definitly are making more than 5cuts/manifold.... **** you said you make 8 cuts for the collector alone..









i see a bunch of place's where there are small spacers or 45's/90's that are cut down. + alot of exessive bends..

Oh if the collector counts than I make a total of 12 cuts per manifold, but I pre make all the collectors on a mill so I guess I just didn't even think about it.

There are only 2 cut down 45's, one cut each. None of the 90's are cut down. Than there are 2 straight pieces, one cut each. So as far as cutting go's its not nearly as bad as it looks ( I know it looks pretty hectic). The bends I have are there so I could maintain equal length (within 3/16", I'd like to get down to 1/8") and use a 1-3-4-2 firing order and still clear that stupid rear motor mount, the crappy cable shift, the firewall, the raintray, and the new intake manifolds I am making, its a counterflow head. Dang there sure are a lot things to hate about vw's now that I think about it

Is it just me or does the manifold picture look really.. busy? Seems like the runner design could be simplified w/ less bending, dipping and dodging. I'm no expert just wondering.

They are really busy, a lot more than I would like, I am working on trying to make it better but there is a lot of crap I have to clear, the biggest hiderance is that rear motor mount, than making everything truely equal length, than using correct cylinder pairing. Vw's are gay

your manifold is way better than what that other guy offers.

Thanks. Another thing that doesn't help the visual appearance of my manifold is that I am using 1.25" weld el's not 1.5" the 1.5's have a bigger CLR so the transtitions look a lot longer and smoother.

Here are some pics of the other guys manifold, apparently they think this manifold is the holy grail for diesel performance:

is it just me or why is it that all vw conversations involve chips. One of the replys on that forum was "what chip do i need for that manifod and turbo?" I mean seriously everytime i talk to a vw guy its all about chips not actually tuning there car. sorry dont mean to try jack this thread but damn i am sooo tired of "well i have this turbo, this exaust, and this bov(yeah bov) so that means i need chip x and i can run 12's all day." are there no tuning solutions or what?

Well for gassers this is definately true, there isnt much for tuning solutions, but there are a few select guys who arent complete tools and tune their own cars. For a diesel you wont make and additional power unless you add fuel and seeing as how TDIs are electronically controlled you need a chip. Apparently there will be some affordable obd programmers comming out so people can download different maps from the net and try em out but its still not like they can make their own. There are a couple companies that specialize in custom chips, but you still have to buy it and either send in your ecu or drive to one of their locations to get mapped.

Personally I build mechanical pumps for my engines, they make a lot more power, they are a lot more reliable, and I can tune it however I want. I am pretty damn sick of idiot vw guys, I am sick of hearing crap like head porting is useless, tubular manifolds arent as good as log manifolds... etc. I cant wait until we get honda diesels over here!

Thats something I would like to test, what flows worse, a log or this

haha , didnt realize there really was no readily available tuning software for vw's as there is hondas.

Yes, but that doesn't make it anymore pretty. I just hate VW's.

And you know you missed several points in the welding right?

I know vw's suck But oh well they are the only diesel engines I can afford to rebuild and blow up.

Yeah its not done being welded,this is just a prototype, this isn't the way I want it, while it works it doesn't fit quite the way I want it to and its ugly like poop.
