Depending on what the powerband ends up looking like, may want to invest in a different converter... if anybody even makes one.

sick430

gorgeous work! keep us updated.

swedepat

just a teaser, need to grind a lot and seal it all up.
But i´m getting there

///AchMeinGott

The intake is magnesium isn't it? Is that just the outer shell I'm guessing? What are your runners made from? Does magnesium present any problems when welding?

swedepat

It´s hard,, really hard.
but with patience it´s possible.
the runners are aluminium.
it welds 'fine', but cracks really easily when cooling off.

The hard work is the cracking problem.
But if you get a weld with no cracks it stays together when it has cooled off.
It doesn´t get pretty at all thou *lol*

But, the rest of the work now is with plasticmaterials.

The very best is to own a big *** 3d printer and print out a complete manifold

sick430

We should do that. If someone has the cad skills I can print them out!

///AchMeinGott

They never did one for any Mustang, so it's a slim to none chance for this, but as long as the injector housing/hoses/etc are the same on all N/A 55 cars, FAST could make a killing with a composite manifold. If there was more then 1 or possibly 2 exact versions, forget about it. Even the intake for the limited production 7.0L LS7, if you know where to look you can get a 102mm intake/throttle body for $1300.

sick430

ALL M113's so 430, 500, and NA 55 use the SAME intake.

Once the actual CAD is made the mold is super easy and cheap with 3D printing.

swedepat

i will test this build before going further.
I know a guy who can 3dscan complex forms.

sick430

Lets do it!!!

swedepat

It might be easier than everyone thinks to make a new upper manifold for m113 NA engines.
One can use the lower part as is and just model a new one on top.
I got a friend that´s really competent in designing in CAD.
Attached picture is some of his work.

i´ll ask him if he want to design an upper part that will ease the process of 3dprinting.
However, i will still test my homemade first.
If no gains, there are no use of going further.

And, night before today i was out testing car at about 00:30 , temprature was 14 celsius.(57 fahrenheit)
and the gains were really noticable, it increased topspeed on the quarter to 118.5mph
this makes me open an eye to restrict heat under the hood.
I´ll wrap with heat deflector and coat as much as i can the coming weekend.
I want that performanceincrease at daytime too
Well,, a part of it anyway

///AchMeinGott

Do you have the long, short, and your runner lengths so we can compare the end results if the new runners are too long/short? Obviously everyone has their own "ideal" curves but still.

And does there appear to be any way(and I know this is extreme) if one created a custom manifold, to flip it around and have a front mounted throttlebody? Not sure what all is mounted to the front/back of the manifold.

swedepat

A frontmounted throttle has been in my mind, but there are problems with that.
The engine has the camtransmission exactly where it´s best to place throttlebody.
And for tuninglength, let´s say it like this: it´s NOT tuned for a sporty engine as std.
More tuned to work ok in heavy application, like trailerdragging in an ML500.

But my experiance also says to me that with a manifold that doesn´t restrict the engine doesn´t take away any power, like the std manifold does.
It adds all over the curve with an extra gain where it is tuned.

sick430

Cant wait to see the end results!! keep up the great work and share some pictures.

swedepat

Next weekend i will try to give it a couple of hours again.
I´ve been busy refurbishing my new wheels.
Got rid of those 20" rims as the performance was really really better with smaller overall diam.(tested std rims)

This is from today, left them at local tireshop to get them mounted:

swedepat

This is interesting.
Costs, roughly?

Rgds

swedepat

I came home late yesterday from a dragrace event.
Just did an hour of work, will spend a couple more today.
But i feel more and more i should go live and make a 3d model and go live with 3d printing instead.

sick430

Once I have dimensions (CAD preferably) I will be able to figure out the cost. need to know the over all dimensions to know if it will fit in the printer. Also what material would it need to be printed in?

swedepat

yes.. i will get back to you.
I read one could cut them into pieces before print, then epoxiglue them back together afterworth.

sick430

Being an intake I would love for it to be a one piece build. These engines are very particular to intake manifold leaks. I have had mine apart and was able to put it back together with one issue. A friend had a leak that caused the car to be almost undriveable. He ended up replacing the manifold as he could not get the leak fixed. I feel that there would be a good size market for this. It will fit ALL NA M113's (430,500,55's).

swedepat

Slowly getting there.
A lot of cleaning up to do.
Then i´m waiting for my flange to arrive.
A friend of mine is getting it watercut for me.
In picture, almost done with boxing it in completely.

swedepat

slowly getting there.
grinding the flange by 'hand'.
Only airtool for headporting as aid.
takes time, and doesnt become eyecandy.
But!
i don´t care.
this is an experiment, if it becomes an success i will go on developing an 3d model and then decide if print it out or cast it in alumium.

sick430

Love it!!! As soon as its done I can start playing with the idea of 3D printing it. We will need a good CAD drawing. But it should be relatively easy, as it will be a one piece unit.

Let me know.

swedepat

I got a lot of logged runs of 1/8 and 1/4 mile.
Best topspeed in 1/8 is 93.85Mph as is, as we speak.

So this weekend if everything is coming together i will test the manifold.
If more power i should get more trapspeed, only logic.
I´m excited about the results.

sick430

let us know how it goes.
