Seeing if there would be any interest in some billet intake manifolds ?
dkjenis has produced one for his twin turbo project and I reached out to him about possibly making some for the forum members if there was interest. He said he’s not sure 100% final costs but it would be in the $3000 ballpark. Obviously the more people who wanted one the cheaper it would cost but just seeing what the interest in such a piece would be ?
Ya as the superchargers come down it isn’t as appealing but the twin turbo potential with this manifold is super exciting. Would be some more custom work to make it fit versus a supercharger kit but nothing that should be too difficult. I would suspect there would be some gains even on a na motor with just this manifold.
It's a nice piece, I'd be interested. How would the intake setup work for N/A setups?
This along with a nice set of cams would make it a really aggressive setup.
im not sure the exact final figment but you would need to get a throttle plate of some sort to bolt onto the front of the manifold and then do some piping to the mass air meter and filters
But yes with some custom cams these should work well, they may even allow the sls cams to make power on the m156
You could reuse the factory air flow sensors albeit you may have to do some kind of custom rerouting or housing for them. The throttles could be reused with a custom throttle plate/bracket or you could go with a large single and I’d imagine some tuning would be required
Yes,, I don´t get the AMG taxes..
It´s just a car.
That manifold, I have built almost equal model myself, but for 4 cylinder engines, and what did it cost?
About 500bucks at the most, more like 350.
Double 500 and you get 1000, make some profit, say 50% you get 1500bucks.
Flange 30$
Runners/velocitystacks 40$
Sheetmetal 60$
Different small things i put in the lathe 10$
Weldingrods 5$
Argongas ~100$
Electricity 50$
I came up with 295$(590$) in this simple list.
Not caclulating manual labour, but for 1500$ you get about 800-900$ profit.
Should be enough to pay your country´s taxes and still get some money left.
Picture of my manifold i built(i have built several more, but later on i made a presstool for the velocitystacks to cut costs)
And a friend of mine who builds custom manifolds for Audicars AND got a company so he needs profit, he´s most expensive manifold is 1200euro, (about 1400 money´s in your country)
complexity to build with dual plenums should compensate for four more runners to weld and you get fuelrail, http://furans.se/buystuff.htm
Bonuspic, I also built the exhaustmanifold, downpipe, well everything,
This car is an old Opel Kadett GTE fwd car a converted to 4wd with toyota celica driveline.
So build some if it’s so cheap and easy and sell them for $2000 and you’ll make a killing and we will all be grateful. Of course you need a cnc machine, hours or rnr and then a solid chunk of billet (yes it’s billet, the top plenum body appears to be welded sheet aluminum but the runners abs manifold plate are billet. You would probably be losing money at $2000 to be honest….

Offended?
You go ahead and buy, it´s a free world! *thumbsup*
By that it is also free for me to say what i think about it.
And if it is billet(the bottom) you actually earn some time, while machine is milling you can build the top hat.
I´d like to see more detailed picture of the bottom before i am convinced it is billet.
Sidenote!
You will lose a lot of bottom end torque with those short runners, not too good with oem turbine.
And suprise!
I am an cnc operator/programmer as my profession.
And got some 35 years of experiance making my own stuff, making things faster.
I feel the same about those overhaulkits for the camgears, insanely overprised.
At $3k I’d be interested. Under the assumption that it’s plug and play for the most part and there is data to support it. If it requires too much custom fab or relocate bunch of stuff, no thanks.
No, you are claiming you could produce one for A significantly lower price. So I’m saying do it. You’ll prove this guy and us all to be wrong and make a bunch of money selling them on here. You claim to have. A bunch of experience which I’m kinda questioning or wonder how much you charge for labour. This isn’t a slap it together in an hour or two process.
When will you have a prototype ready for us to view?
honestly any discussion of I can do it cheaper...really has no place in most discussions because SOMEONE CAN DO IT CHEAPER THAN EVEN YOU.
being a negative body in every conversation at time becomes an eye sore.
as far as on the market, if an individual or company produces something cheaper and is publicly available then share it, otherwise you're just being annoying.
Yes,, I don´t get the AMG taxes..

To make it simple, assume engineering and material costs are the same regardless of vehicle. If you can project a minimum of 2000 (LS7 platform) units will sell, the consumer cost will be much less than say if it's 50 (M156 platform).
