Has anyone ever made a homemade Intake system successfully Attached Image

My crude drawing would show 180 deg. silicone tubes from throttle body then in to a cylinder with appropriate vacuume attachments ,and then a cone filter on the end... (IMG:style_emoticons/default/confused24.gif) (IMG:style_emoticons/default/confused24.gif)

How about 180 into the factory plastic box - little fab needed.

Or you could do ABS tubes, kinda generic looking but easy to work with.

Also if it was mine I'd go straight back and not 90 towards the battery.

I removed the cross brace from my lid with no ill effect. Do you still have the rain tray mounted?

You could possible just save a bit off the stock intake couplers and gain enough to clear.

If it was me I would mark the firewall and move it just a tad with one of these (IMG:style_emoticons/default/smash.gif)

Sometimes simple is just better, and if you want to take it back to original then it is easy with a bit of (IMG:style_emoticons/default/sawzall-smiley.gif) and a (IMG:style_emoticons/default/welder.gif) Easy enough (IMG:style_emoticons/default/confused24.gif)

Or you can spend some time getting a forearm work out with hammer and dolly and slappers etc..

Yes,.But the whole assembly was higher than the mounting bracket on the fire wall/bulk head for the lid so I knew it was way tall

but removing the bracket may be helpful still Thanks

Yea,..Kent just the breather box I cut the big fat 3 " pipe of the end of it to make it fit as I wanted it to,too keep my axels in line,

and Yes Stephen Iam not against massaging that bulk head a bit,.but if I cut it then I wonder if my back pad and seat would fit correctly...
which I will be looking at all that tomorrow to see how bad it may be or not .

Yes Chris I intend to do that tomorrow,.. Thanks Guys..

IT would with the stock ECU.

I am going to build a center manifold with 6 equal runners, one large TB off a Shelby Mustang and the runners will have Velocity stacks ends like the current M3/M4 does. And running some form of aftermarket EFI, I only have 3 different ones on the shelf to choose from and I really don't think I like any of them. (IMG:style_emoticons/default/laugh.gif)

The issue with the stock SVX unit is the variable chamber and the running was done for that manifold. If the IRIS system is not functional, it can cause some odd flat spots.

ITBs would work also, but have all the issues of ITBs. But would sound so good and look even better (IMG:style_emoticons/default/drooley.gif)

I made a full custom setup for the bus on the Corvair. Same concept would work on an SVX, but it takes time and trial and error. I the plenum volumes correct, too.

Yes Dr.Evil,..if I stick with the tube lenth and its 3" diameter with all the vacuum ports it should work even if I did 2 intake tubes into the box as long as I have the air volume...I think it could work out

Another approach, Frank. I used this set up. A silicone elbow and use the existing air temp sensor with it.
