Oh my lord look at this piece.... Rising RPM

Does anyone here have one? Thoughts? Concerns? spool characteristics compared to a long divided header? The price is pretty high....I'll probably be buying one though

I wonder how many hours of machining goes into one of these.

If I had to guess a machine does all the work...the hours went into the CAD design..

It's definitely unique! I probably wouldn't give up my twinscroll manifold for it. Having said that, I would love to see a a dyno comparison using this manifold against a twinscroll keeping everything the same and see how well this manifold stacks up.

it was just recently released and built to order so i think it'll be a while till se see one with a dyno. maybe a group buy? any one interested in setting that up?

id like one in the future! sexy as hell!

that price is not high for a manifold

Wow it looks great though!!!

Looks like a great piece; they make quality products. I do think it should have been divided though/made it like the S5 stock manifold.
It probably wouldn't take much for them to change it.

Everything from RisingRPM has been top notch. I wouldn't second guess the quality of any products from him. If you have any doubts, send him a message on twitter. He usually responds within a day or two.

Probably fewer than you think.
Note that all the "curved" exterior parts were left as fairly rough step cuts, that is a timesaver (compare to interior curves where more time was spent because it matters).
Also, given the proper equipment (which they probably have) you can make some pretty aggressive cuts in aluminum.

It would also depend on how many axis their machine operates on.
If removal of the billet and refixturing is required, that would significantly increase the time.

I'd guess somewhere around 1-2 hours, I hope someone more knowledgeable chimes in...

that actually looks a lot like my cartech manifold, except the cartech fits a t4 with the NA intake

After the CAD work, programming, and expediting of the process, I'd be surprised if it was booked for an hour. The thing that that surprises me is it could easily have been machined for a "semi twin scroll" with so little extra effort and a secondary operation. Split at the top but not all the way to the ports. Would this still be an advantage? I don't know.

Or, just weld the divider in.

After looking at it closer, I think it could be machined with a divider. Centered at the turbo flange, just not centered between the ports

I think the benefit here is you can still run your emissions equipment but not on a stock ecu. Wonder if you can make the haltech run all emissions equipment. On my To4B with HKS log manifold I didn't run no emissions so the haltech was very easy to wire up.

the ACV only uses two solenoids, so its 2 more wires...

This would pointless, it wouldn't be providing any benefits and might actually do more harm than good as the exhaust gases would have to merge to be divided. Kind of like having a y-pipe in you're exhaust when it's not needed. It's either twinscroll or its not. The point of twinscroll is so that each rotor's exhaust pulses are feeding the divided housing in the turbo for faster response time.

My question is how well does the exhaust gasket hold up since it will be directly exposed to exhaust gasses due to the large open area between the ports.

driftxsequence

iTrader: (8)

That was my concern as well rotarygod

fc323

Yeah..isnt something going to happen since the exhaust is touching the engine itself instead of the designated housing ports

Valid point. One could get well over the iron with no problem. The center? That could be done by finishing off with some hand work and a die grinder. The divider can still be stepped over, or curved, whichever you prefer, because the manifold is already being machined in three set-ups including both runner sides.

But the factory gasket is what it is so, the obvious solution is to make your own gasket. Shouldn't be too hard to whip up a metallic one if you have the ability to make the manifold.

As stated above, it would only interest someone that wants a stock looking set-up and using a lot of stock components.

Or,as I said before, bend one up and weld it in.
