i made this last week and going to put in with new halteck tell me what u think. the lower is a water cooled intake man. i think the pic will show up

Might be functional but welding leaves much to be desired.
Where did you get the intercooler piping adapter, looks like a nice piece.

my friend made it at his work (cnc machining).
i am hoping for 410 to 420 rwhp @ 10 psi so i am going everything i can to get the power down to the wheels

Rotary?Cool

Looks.....you could have grinded a little.

i'm assuming you're running chilled water through so it acts as an air/liquid IC....interesting way to do things

do you have any pictures of the LIM without the cooling casing around it? did you make a new LIM or did you just put those panels around the stock one??

any pics of any of the custom fabrication done??

let me rephrase my questions

what is done on the LIM under that casing? is there any internal work to the plenum/runners on the UIM? can we get some shots with the throttle body off and before the casing was welded around the LIM?

yea those nice coolant passages(stock ones) will help alot, one suggestion, block those off. second, you should dyno test this with stock uim and you uim. I bet you alot that the stock will also make alot more power, and torque. If you look inside of the stock one it is a dual plane, causes the runners to be longer and shorter, this gives you better low end power by having the shorter runners. Your mani completely removes that, and offers no way to help low end power so... If you do make any power from this thing (if) it will prob be all high end. There is a reason that nobody really makes intake manifolds for our cars, (i know some do) ANd mainly people only make them for cars that sell a shitload. Is because so much reasearch and design has to go into it. You really have to study flow characteristics, Flow charts, USE a flow bench, and dyno test the **** out of it to see what it will do.

The lim you made could work well if your using water from say! a separate tank or someting, but if your planning on runnin a coolant line thru there. BAd idea, it will just make it hotter. If it just retained water then that would heat, and since you would have the water, more metal, and you made it that much closer to the turbo, Your intake temps would climb.

I hope that me posting this doesnt offend you or **** you off in anyway, because im all about trying new ****, If i can find it ill send you pics of my manifold, i made Tubular, and was gonna have jet coated and thermal wraped to keep hot air off of it, but aborted the prodgect do to me getting an RE motor and not using my S4. I would like to see a flow chart from it if you ever get a chance to get one, and also a dyno chart, It would really benifit you also so you could see where you needed to make improvements and get controll of your power band.

will i made this manifold so that i would have a good high end because my car is bridge ported and needs the high end.the stock manifold is made for the stock car so if u port it then you will need more air and to do that i made a new intake manifold. my last dyno with stock computer and stock intake was 381 @10psi and with the new halteck and intake manifold i want to get it to 410 to 420 @10 psi. and if it does not work that good all i can say is i tried.

chris-reedtn

yea thats all you need to say, i think trying new **** like this is deff a good idea. Im all for it! i hope it does work out pretty well, and u can use this as a starting point to do some reasearch and maybe make something to sell and change the fact that there really isnt a holt lot of aftermarket parts for the fc!

Check the below link. I went with a GM 3" T-body. Having the T-body so close to the motor will move your torque curve up. Mine was still climbing when I let off at 6400rpm's the last time I was on a dyno..
I like your idea with the water in the LIM. Nice Job!
I think your set up will work for you, one question though, why the stock t-body?

Hey rotorracing
Great idea, don't be discouraged. The aussies have been using this set up for the longest for the fastest mega HP rotaries. The only difference is that they use a single throttle body in the setup, and I am sure you will meet your HP goals quite easily, considering drivability is not a major concern.
I will see if I find a couple of pic's so you can see the aussie setup. On a positive note ......... if you and your friend decide to manufacture and sell those intake adapters, you might just make enough $LUCHI$ to afford some TIG welding for that new intake manifold setup with the single throttlebody you will be making.

Here you can see a typical setup similar to what you did.

nice pics , i used the stock tb because it will be a bolt on intake(if i start to sell them) but i have to see how good this one is on the dyno.

holy hell that is ******* awesome!
