fab up plate to match head intake and weld round tubes off of it with about same ID as head ports witch can easily be port matched to head later.

next the little round circles I traced off of a dime represent mikuni slide carburetors sources from old motorcycles with same id as manifold/head.

seal all the little low speed ports in the carbs with jb weld or similar, remove main jet orfices and replace with bolt to block temperarally unless otherwise needed, remove main jet needles from slides.

effectively turning 4 slide carburetors into individual throttlebodies.

weld tubes similar to head manifold to intercooler at witchever angle orientation you need for hood clearance as close to the hood as possible at an angle with the carbs on the low side.

plumb other side of intercooler to charge pipe and turbo around the back side.

cut hole in hood equal to top down view of intercooler and fabricate tin knocker style an open box on the bottom side of the hood that will seal down to the top of the intercooler around the edges.

slap yourself an as gaudy as you like hood scoop over the hole in the hood to effectively ram air through your intercooler.

possibly 12v draw fan on underside of intercooler also.

im not sure yet about how to put a throttle position sensor on one of the slide carbs, maybe on gas peddle its self... thought still in progress.

I know your probably thinking "why use carburetors for throttleboddies"?
well because they are readily available and I am very familiar with them, cheap, plentifull... and performance guys much prefer a slide over a butterfly so I believe the same should apply to a throttle body.


andd.. i do believe someone could come up with an ingenious way to utilize the existing main jet portion of the carburetor useing whatever id jet you want with matching needle, or installing atomizer nozzels for your meth injection setup right there under your throttle body slides.


so lets recap...
head manifold plate=$50 diy
(35mm ish?) mikuni carbs=ebay $200+-?
intercooler=$150
intercooler aluminum tig work=$1-200
charge tube plumbing=$100

sounds quite cheap for an individual tb set up with much more effective top mount intercooler
nice short quite straight charge pipe plumbing
put blow off valve and waistgate pressure sending tube wherever you wish on charge tube or between carbs (TB's) and IC

then again i am only 23 years old and far from an expert but this to me really looks like it could work well
maybe im missing something... you tell me

but i do believe this level or original creativity deservs at the bare minimum trooling responses bashing the idea

thank you for viewing at the very least

and here comes the ingenious way to utilize the carburetors

(oops not sure what happened there)

make myself a meth bottle I can mount higher than the carbs that will be safe at atleast 20 psi with a non vented cap.

pressureize the carb float bowls and my meth tank off of my intercooler where the carbs mount to it, most likely where recirc blow off valve, overboost switch, wastegate sensor will go.

should carburate the meth solution right into the charge air, leave low speed ports in carbs unplugged, can shut them off with idle enrichment needle adjustment anyway I do believe.

I would definitely have to source some insanely small main jets and appropriate needles. may have to make them, jets easy as pie, needles a bit more tricky but im in good with a machinist.

note: will need perminant vaccume attatchments on manifold runners, remove those vaccume lines for synchronizing carbs and replace.

I must be forgetting about vaccume lines for CIS... am I going to run into problems trying to keep CIS functioning?

Here is a pic of a seriously high power 931 (Joakim.s) with bike based ITB:



Top mount air to air is a pretty bad idea at that spot, cooling flow is severely limitied. Probably better to have a water ic if you will integrate it in the manifold, just like many modern engines have today.

BTW, I have stopped writing on this board, beause the only way I can log in is via iExplorer 8, whih I only have at work. IE10-chrome/chrome mobile and opera cant log in on this board. I dont know but it might be the same for other people..

You would need a massive hood vent to feed enough cooling on that IC
I'm curious about the 50$ adapter plate.
Could you explain how you would do it as this sounds too good to be true.

about connecting ot the site, I believe this is on your computer.
I use chrome, IE9 and safari without issues.
IE10 i could sort of understand but chrome works fine
If on a windows machine, in those situation I would suggest trying to log on your machine with another user profile to see if it wouln't be a case of corrupted user profile.
