Hey guys! So I really want surge tanks for that 30whp or so you get but not really into paying $1200 for billet tanks. So I started teaching myself cad and Fusion 360 and I'm starting to design my own billet surge tanks and wanted to ask some questions when I finish the complete design.
It's very rough at the moment but I wanted to ask you guys if you'd like me to open source it so you guys can get your own tanks made. Obviously, you'd need a custom tune for it but I will be attempting it first on my own car.
This is what I have so far about 30 mins of work haha. This part is the gasket I reversed engineered into Fusion and will be fusing it together with a base plate I measured up to fit. It has recessed holes for bolts and I will be designing a top hat that will bolt up that's open to increase airflow into the supercharger. So a two-part design
That's great you are giving it a shot. I am very close to taking two tanks and splicing them together for extra volume but there is not enough material towards the front for extra room.
You can clone our original tanks , but just make them bigger and mostly up front on the tank where it is real small.
Keep us updated !
Would love to see an all in one surge tank and intercooler core. Do it right, and it will have a pipe over to pick up the stock style Y-Pipe. Would be really nice packaging.

I think this would be very easy to make once the compete surge tank design is done. Just weld a core to the side and design a pipe to connect them both.
I’m going to try and design the top hats to have recessed holes to look cleaner when it’s on the motor. It’s more or less going to look like a taller version of the oem surge tanks
I would be interested in your progress. I would in Solidworks and have a CNC mill (3-axis) if I can be of any assistance.
Once I finish the design and 3d print them to make sure they work then I can definitely use your help. I can pay you for the material and send the fusion file over to get cnced.

Keep me in the loop. I look forward to seeing your finished design.
I’m not really a big looks dude so making these things look great isn’t going to be something I’m shooting for. Edges are not gonna be rounded probably unless I teach myself how to do that in fusion. (Don’t know how hard it is). Just gonna shoot for a similar design to oem for the top hat but all open on the inside. So just a sloping top rectangle with a 2 inch inlet.
Nice! It’s great to see you involved in making your own. Keep the updates coming.
Thanks man! I was bored so decided to try something new. Going to try and complete the design this weekend and get it 3d printed to see if it fits correctly.
Don't bother sloping it as that's where the lower flow is due to smaller chamber volume. Keep it the same all the way through if you can.
My idea was to cut the top one intake , than cut the top off another only taller, than weld it back together.When done it would look factory but just a little taller with extra volume. Problem is the passenger tank is really close on that cylinder and there is not much room for improvement. Driver side for sure. Pay attention to the feed inlet tubes as they are restrictive as well from that bend and the kinks for clearance.
Also screw the looks....performance is what counts for me !!!

Hell yeah man, definitely going to just make it a solid rectangle then ahaha, I feel as the slope helps push the air to the furthest cylinder, maybe I can do a flow simulation to see if that’s true.
Just imagine two big *** blocks on top of the supercharger ahah. Honestly if it’s billet aluminum it would look better then the oem and I can also had the AMG label on it as well.
Also to add, I can design a bolt on 2 inch inlet to the surge tank for people who want a nice top mount intercooler set up. For example a bolt on inlet then you can take a 90 bend and weld it to the bolt on inlet and the intercooler. This should in theory support the weight of the intercooler making it a sweet bolt on design. This should almost hide all silicone couplers in the rear and look sleeker.
Wanted to add this. Cost for material would be around $330 but I just went to one site for 6061 billet aluminum so could be cheaper. Unsure how much manufacturing cost would be but I wouldn’t assume more then $200

Once you have the exact stock sizes needed let me know. I have material sources that should be able to get the cost lower than that.
When you say "manufacturing cost" are you talking about machining? If so, $200 sounds very low. It will all depend on the amount of machining time, fixture costs, and number of operations. Once you have a design that is pretty close I could give you a rough idea of run times.

Yeah I will let you know once I finish the design. Currently going to be 18 inches long 3 inches wide and probably 5 inches tall.
Ok finished the design, as from what some of you wanted I just went for a nonsloping design and just made a big rectangle. Here is what I have. Going to get it 3d printed to make sure it mocks up right.
Tooooo tall chase!
I would say 4" max but I will measure tomorrow for exact numbers that will fit or check your car as well.
Awesome effort !!! I'm all over this for sure.
They key for me will be all aluminum elbows INTO the tanks ....not rubber/silicon.

I measured the rear height as 4.5 and I have a half inch base plate. Assumed I can go all they way across with it. I can always reduce the size if needed.
