Critique this manifold!
My brother is considering this manifold for his car, what do you expert welders think?
Its weird how cyl 1+4 merge and 2+3 merge (instead of 1+3 and 2+4). Anyway let me know what you guys think.
(this means you engloid)

Re: Critique this manifold! (Boltz)
that manifold is for the evo8 turbo wich has a divided inlet like that , and the threaded ares i think are for like a heat shield or some thing

Re: Critique this manifold!
It looks ok to me. It looks as if it's pretty much a 4-1 merge.
The welds look ok from a distance.
It's awful shiny. It reminds me of the SS Autochrome manifolds. If it is, I've heard horrible stories about their stuff being the worst to crack.

Good point...I didn't pay much attention to the turbo flange.

Factory anti-lag? There were Evo 6s and 7s with this set up, it takes recirculated air from the charge pipe and tosses it in there, doesn't work very well either. True anti-lag has nothing at all to do with directly injecting anything into the exhaust manifold. Well I shouldnt say that, in the early days of rallying turbo cars there were some crude set ups.
In regards to the manifold, isnt that an SS autochrome piece? Looks like the ebay specials.

Any car can be equipped with anti-lag, even some stock car computers (if properly tweaked ) can support the system... the stock engine/turbo wouldnt last more than 10 minutes, but its well worth it when its needed.
Brandon was referencing 'old skool' anti-lag. Todays systems work in a similar presence with the old, but are far different. Basically, while the combustion is going on inside the cylinder, the exhasut valves of that cylinder are opened, forcing burning oxygen/fuel mixture through the turbine... doing its job and keeping the turbine spooled. This is all when the clutch is in, no load on the engine, or awaiting launch.
A previous article I read on the WRC comp. cars made the statement of that the newer form of anti-lag produces as much as 3bar of boost while under anti-lag.
Back to the point of the manifold tho, its twin-scroll for sure. Vtec for turbo's

Re: Critique this manifold! (AnarKhyKustoms)
i heard those rally antilag systems destroy turbos in 1 race because of the serious explosion is recieves.
duno if thats true or not.

Lets straighten some things out here. A "stock" engine and turbo can last with anti lag, most rally cars dont use some super special or exotic turbo. A group N car such as a wrx or an evo will have anti lag and use the homologated turbo and the engines are very close to "stock", nothing super advanced going on there. Its very hard on parts, but 10 minutes is a bit over stated. A typical rally here in the states is 50-150 stage miles and not every ALS using car gets a turbo before or during every event.
I was not referring to old school anti lag, Im talking about current cars. The system in question that uses these ports is not a true ALS. The craziness people are thinking of is not accomplished on a stock E6 with this manifold. If 3 bar is being made with anti lag it is during launch control mode and the engine is not producing that at idle. Idle with anti lag engaged isnt true idle anyway, either the IAC or a part called a throttle kicker is used to raise the idle.
I have seen an open class evo4 here in the states sitting at "idle" with its ALS on, it was making about 8psi and was holding about 2,500 rpm. Also had my butt in the seat of a Group N spec cosworth escort with ALS, with the mild setting turned on the cossie would make about 6psi and then taper to 2-4 if no throttle was input.
But about that manifold, you should ask some of the guys on evolutiom.net It seems pretty popular.
