I started making the pieces for my Intake . So far I made a die for making the runners. I searched all over the internet for the right size runner material with no luck, so I decided to make them.. The die took me a couple of weeks to make but it was worth it. I got one runner made so far , it wasn't that hard once I figured out how to go though the process of lining it up square with the right size of aluminum needed so in the end of the pressing process it butted up with a small gap for welding . Im also in the process of making the head and plenum flanges as well as the throttle body flange. Im trying to figure out a way to O-ring the plenum flange with a bolt on feature so just in case the plenum I designed doesn't work I can just unbolt it and only have to build a new plenum instead of the whole manifold . Here are some pictures of the die and a runner I made with it. Also is a couple of the big chunk of aluminum im making the flanges with . It started out at 6"x28"x2" . I cut it down the middle making it basically a 6"x28"x 7/8" piece. Soon it will take shape to the size it needs to be... Its a lot of work though..

Looking Good Charlie.

That is the way I have seen McLaren Fabricators built intake runners.
Difference is they laid out lines on the material and formed a series of small bends to get a bigger radius bend for each corner of the runner 1/2 shell.

Thanks Tom...

This is 3/16" plate. Should hold high boost pretty well...

Charlie, looks like you started fabricating your intake. Looking good!

Thanks Edwin .. Its going to be a winter project..

Hope it works.. lol

Nice job on the die to make the runners! This will be interesting to see what this manifold looks like when done.. ..

Never heard of a bottom fed manifold before...

Thank you..

Yeah its for better distribution of the air..

Will it actually work that way.. I don't know, but im going to find out.. haha

[RUDOLFSSON]

Nice !!

Keep us posted on the progress.

Can we BUY intake flanges?

I haven't seen any that's why im making my own.. Same goes with runner tubing. Haven't seen those either so I just made them ..

Mopar but same thing really

Hey Billy, Do you know much about this car? I wonder how wide the slot is feeding that plenum? That's the same idea I had for my 8 cylinder build I doing..

Thanks for posting this . I've been looking for pictures like this with this design ..

Got any others or different angles of this one? We all know you're the king of pictures ! Hahaha...

Billy, they did a really nice job on that "Bottom Feed" Intake. Whole package should be "Bad to the Bone". What Kind of times was the car running?

ps Charlie, We did testing on the "Slot" on a Audi Manifold designed in production with the slot.
The Audi intake was adapted to our 4 cylinder engine. Mixed results (if it did anything better, it did not show up on the dyno) vs the simple "bottom feed bounce off the roof" design by Mahovitz.

Thanks Tom. I like the second picture . Would like to know more about that one..

As you can see the air went into the throttle body and then into a large plenum.
The second plenum is where the Intake Runners feed the engine. It is a large plenum too.

The slot would be between the 1st plenum and the second plenum. It would be clocked to point about 5:00 and go into the second plenum, Air would go thru the slot, bank off the roof of the second plenum, then the air would continue on to the runners at a much lower velocity and higher density.

I lot of monkey motion trying th kill the air from all packing up at the rear of the first plenum.

Center feed, bank off the roof, seems to work the best and uses only one plenum.

Ok , so what are your thoughts on this design Tom?

How's this work out by splitting off right at the throttle body to feed both sides ?
