Reversed intake manifolds

[urS6Tom]

Could someone explain the theory behind this? Is there a thread on how the reverse intake works?

@ Billman
The IM does fit with aircon according to Repo (read link at bottom of pictures)

@ Tom
The reverse intake improves response as you are considerably shortening the intake so the turbo will spool more quickly.

you can also say that the cooled air does not need to go over an 900degree turbo/exhaust manifold before it goes inside the engine

So its all? No any other inlet manifolds?

I don't have any other pictures,bul I'll make to show you...
This it original IM ,but sliced and reverced

This belongs to a friend of mine...:

that looks good, does it work well? it would be a much cheaper way for me to do it, can you still use the same throttle body and everything? and what power difference would it make?

that is something my mechanic proposed to do as well.

[quattrostyle]

any pictures of how it's done? I'm very interested.

He has several styles and options... high quality stuff!

That sliced and reversed one looks very nice. I guess thats a cheaper solution than WT and other ones. Would be cool to see pictures of its development.

Yes,you could use the same throttle...
Once the IM has to cut trough the runners,under the body and when ti's reversed ,there is another slice in the area of angle of body,close to the throttle(because the throttle comes too high and it will be impossible to close the hood )
When the front part of IM is fixed and fitted,you only have to weld it to write angle
I can't find a pictures of the work process ,but I can use photoshop to show where are the slices
There are and other options for IM ,see our site:

p.s. my car's IM,before it was mine ,was into a 500hp S2 ABY(the white one ,next to mine on first picture) and it worked properly

I'll do my best to find some pics

I'll do my best to find some pics

Please do! <:

[max_s2]

Yes, please also some pictures where it must be cuted and so on. I'm very interested as I dont have big budget for reversed IM

Hallo ,guys!
I've searched every computer that I could ,but I coul;dn't find any pictures of the work process
I'll try to explain to you what's the deal with this IM...it's very easy for a guy who can use a flex and welding machine and have them
In the beginning you must take off the IM and attach it to a table with holes that there are no moovements of the runners..
Here is a picture where I mark the location of the slices
First you must cut all runners into an angle witch gives you a chance to fit it back at the same position,but already reversed ...

....
After the cutting,turn the IM at 180' and than you will see that the throttle with the angle of the IM are too high and this will not gonna give you a chance to close the hood
To fix this problem you must cut almost here,where I mark it:

......

...
After you slice the angle area,you must give the throttle part an appropriate angle ,according to the hydraulic pump....In my case, the IM is at about 10mm from the pump...
After that you will fix the throttle part to this position and the rest ot the work is to fill the holes with some little alluminium sheet and weld it on top of it
I couldn't find a picture above the IM to show you wrere is the slica beneath ,but it is not so hard to do it..
After all that,everything is a question of patience to sruc and polish the "product"
In the beginning of the history of our reversed IMs ,the mechanic guy wanted 100Euro,but in one moment he said that he will value his work ,the price jumped to 400Euro,which is a crime, I think Form that moment till now uniflex motorsport is making only big ,two section IMs with thrompets in there for the most powerfull 2.2T in Bulgaria...
Hope to help somebody with that and forgive me for my mistakes,I'm sure that there will be but I'm not that good with English ,especially with the technical one..
If you have something to ask me about this,I'm always on!!!
