Anyone ever seen one of these in person?

Several vendors have them listed, but the picture looks like somthing else.

Any info would be appreciated. Thanks

 

I saw it at SEMA in vegas, but i dont think they released it yet, and that was a year ago

 

waste of money! For that much you may as well port and coat your stock one for $100 and get the same performance. Besides DC is poor quality. It will crack sooner than later. I would get an equal lenght elsewhere. DC is for ricers in my opinion & a waste of $$$$.
The only thing they make good are suspension pieces and intakes (AEM)

 

I can't opine to the quality of DC Sports, but saying that a ported stock manifold is going to make as much power as a tubular manifold is not true.

 

I'm not saying DC makes the best turbo header but Dc sports is usually not poor quality stuff. I have their downpipe and its a beautiful piece. I sell their headers to honda guys all the time without a problem. their suspension pieces are usually nice too. I'm not commenting on the quality of the header yet because I havent seen it on a car for a long period of time. I assume they are testing it as we speak. dont confuse them with SSautochrome

 

Thanks for the info guys, pretty much assumed that was the case, but I still see em listed at shops.

IMO the DC mani would fit in between the numerous Tai JIC knock-offs @~300$ and the DNP at 600$.

The ported and coated stocker is OK. but I have an admitted weakness for SS tubing and polished aluminum.

If you have ever seen my car I think you'll agree rice isn't my thing.

RNR has been working on a stocker turbo mani for a while but has yet to go public. I'd guess it will be $$$ though. Did Invidia give up?

For the record I think most will agree there is a slight to noticeable gain higher in the rpm band. Durability will never match stock, but hey, don't mod your car at all then.

 

I wouldn't be so sure. That doesn't exactly look like the best tubular manifold I've ever seen; it's not even close to equal-length and it doesn't exactly have the smoothest bends.

I wouldn't be suprised if a ported stock manifold were just as good, or at least very close.

A gray cast iron manifold is also much thicker usually. If it's more than 3-times the thickness of that tubular header, the cast-iron manifold will actually hold in more heat as well, which is good.

i know im very interested in the invidia peice that was supposed to be out ages ago....i also have an extreme weakness for ss tubular bends.

 

The picture in that link is not even a turbo mani and definately not a, Evo mani.

We're not debating the advantages of tubular manifolds vrs. stock cast, However gains have been proven up top. Obviously they will never be as thermally efficient or durable as cast iron manifolds without some extreme measures. I am willing to admit at the level of power I'm currently making, a tubular mani would be more of dress-up part. I see most IC and hard pipe kits the same way...

 

I have actually seen headers cause a loss in power on cars other than the Evo. It really depends on how good the stock manifold is more than how good the headers are.

Since it's so rare for a turbo-header to be truly pulse-tuned (the primary pipe length would be 3-4 feet long), the only gains available are from reduction to flow-resistance ... which doesn't help scavenging nearly as much as a proper tuned header would.

Oh well, there's nothing wrong with a little dress-up as long as there is some gain and no loss.

would porting and jet coating the stock header prolong the life or lessen it if your driving the same daily driver?

 

Doubt it would affect the life of the header.

Hypothetically the coating may extend the life of other engine components (hoses etc) as it supposedly reduces the underhood temps thereby enabling a cooler running engine.

Oil cooler might be more effective IMO.

 

I think I'm starting to like this buschur philosophy

 

exactly..

 

This should clear things up. The DC header has beautiful knife edged merge collectors unlike some high dollar pieces which just mash the pipes in the flange. They also port the collector up to the turbine inlet flange which is a nice touch.

All welds are CNC robotic TIG welds. They're very clean and precise. No crap is left in the runners. It's an excellent piece if you ask me. Check out the thickness on the header to turbo flange. It's a monster.

Here's a bunch of pics for ya:
