right now im just in the research and design stage but this is a project i have wanted to do for a while now so i figured id post them up and get some feed back

originally i was only going to do an itb intake but then i relized this intake design could be converted to a conventional design as well by removing the throttle blades and not boring the the throttle shaft holes and bolting a plenum down to the top that utilizes an tpi or lsx throttle body

as for now i think im going to build this itb setup with 30mm butterflys though i need to do more calculations to come up with the final size the injectors will be mounted at the base of the itb block which will bolt down to a stock lower intake,this will require custom fuel rails

as far as hieght im going to aim for a 6 inch to 7.5 inch hieght on the itb style intake, and im not yet sure on the hieght for the plenum style manifold as i need to dbl check hood clearance and see what i can get for plenum volume ontop of that without clearance issues


heres a pic of what it would look like looking down from the top the blue dots would be the bolts to blt it to the base and also some of tem would be for bolting a plenum down ontop of it on the other design.

i have some cad drawings and some 3d drawings that ill post up as soon as i put some finishing touches on them

if u guys have any design suggestions or ?'s or anything just post up im trying to shoot for the end of the month to get one machined up and on a car for testing

 

opps forgot the pics before but heres something a lil better

itb's



with plenum and one tb (diff intake)

 

going to need somone to test the bottom manifold for me who wants to give it a try?

please no recent new members,looking for somone who has been around a while

 

I'll do it, I'll just have to pick up a gasket set and if you pick me, could I have a picture of it so I know what Im up against

 

bascally its gong to look lkke this




not pictured are how the injectors and furl rails will sit
im going to use a tpi throttle body and tpi throttle cable bracket
so u may have to get urself a tpi throttle cable
tv cable for the autop trans should be the same but m not 100% sure on that

it will be some time as i just ordered the materials to start fab work on it should be here by this comming weekend and take me a few days to start putting it together

essentially this will bolt down inplace of the mid and upper stock manifold, and will require removal of the stock fuel lines and the stock injector holes filled either by welding them shut or epoxyin them closed and removal of the fuel rail , if i supply a base manifold to whoever ill prolly just epoxy the holes shut for testng

killert would u be able to dyno the car if i send one out to you before and after its installed ?

 

I'd have to look a bit I think I could be able to get it dynoed, I'll just save my money up, also I could probably get a lower manifold and weld up the holes for the injectors. If you get it so it will bolt up 100% and everything figured out like that. I'll certainly be the test pig. Just tell me what I'd need to get and would I be able to keep it or atleast get it at a discount ?

 

Why not put some bend in those runners? You will be able to make a shorter intake With the same length runners (on the 2nd one)

 

whoever does the testing gets to keep the manifold

the idea is to have a stright as possible runner , this design will put one bend into the whole intake tract compared to the stock design which has that nast nasty bend in the top of it

 

I take it that these are designed to bolt to a later model FWD lower intake?

 

ill do it i have been around for some time just read more theni talk haha

 

no these will bolt down to rwd lower intakes

 

Not sure if you plan to make both styles or not, but if you need a test mule for the itb setup I'll volunteer, I'm assuming stock hood clearance would be an issue and that it would require some ECM tuning to run smoothly as well? (just dropped in a 3.4 btw)

 

yeah the itb design will be done second and is more then likley going to require some tunning

 

Do you think the TPI throttle body intake should fit under the stock hood? If not how much do you think it will stick up?

 

hey i like seeing fresh designs good work
however the lower part will not line up with the lim as the runners are almost in line on the lim, your pics do not show this.
also, a slight curve in the runners will help the air get round the corner at the lim as you have now created a new corner restriction at the lim junction with this design......

 

the runners arent inline, it apears this way because the lim is on an angle threw the port thus making it look larger.the bend will be taken care of in the base plate of the manifold. i just didnt show it in the drawings as the complex radius and angles is very hard to draw

 

How goes the R&D?

 

i have a baseplate machined out so far and im working on the runers and the injector bung angles

 

Can't wait to see it!

 

I've been looking at tbird M90s lately...a lot, they can be had for $100-250, are easy to find, and really wouldn't require much work to install, been thinking...it would be awfully easy to make up an intake those could bolt too for someone with fabrication skills....I've thought about even just cutting a hole in the UIM, problem is even most aftermarket hoods would not have enough clearance for that I think, though suppose you could always go old school and cut a hole in the hood now that I think about it.....
Anyway, might be a good idea for another intake design.

 

m90 adapter is easy as hell to make,infact i belive gumby has one

 

an almost completed intake just went out for flow testing, baically its the intake without the plenum welded on, when it gets back im going to put on the plenum and tpi tb and send it back out to be reflowed

 

If your still needing some one to test your intake ideas let me know, I can try it lol. I'm gonna try a remotely mounted M90 and see what happens, A/C gotta come out. I wanna see how these designs work, look pretty sweet. Will they fit under a stock hood?

 

yes i changed the design a lil bitthe intakes come with interchangeable runners, i have 3 diff lenght runners that basically bolt in to the manifold

even the longest runners clear a stock hood

 

Im still interest in testing if you'd like.

 

im still some time away from being ready to test on an actual car but ill let u guys know when im ready. unless my own project is ready at the time ill prolly test on my own, and then send one ot for somone else to test so im not the only one with gain numbers to show

 

How about stuff for vacuum lines? My intake is bone stock and it hates not having vacuum lines together lol.

 

there will be a hookup for all vacum accesories

 

Sounds awesome, my car just hates disconnected vacuum lines.

 

17xxcfm as a whole unit
i tried 6 different trasitions fro the round runner to the rectangle port the best flowing runner was 292 cfm and the worst flowing runner was 247cfm

 

so what are stock flow numbers?

 

Got any pictures?

 

i think the stock numbers are in the 170 range iirc

just on my cell phone but i dont get service ere i am ,lol nearest place i get service is about 60 miles away but next time im out that way ill snd the pics to my email so i can post them


im thinking i can improve those numbers about another 50 cfm with a lil more time spent on the transition from round to rectangle , but chances are i wont even mess with it as it already flows way more then would ever be needed

 

I thought they were in the 145-155 range. I heard of a ported stock plenum getting close to 170 but still in the 160's. If thats true then this manifold would be a huge improvement over the stock one, and even a ported stock one.

 

Great work can't wait to see the finial version
when do you think you'll be able to start offering these?

 

yeah this is right 160/170 is ported 145/155 is stock

depends next step is on car testing flow numbers are one thing but i need to do some on car testing now

 

while were throwing around numbers

 

another 2-3 weeks and this manifold will by on an engine dyno for back to back pulls vs a stock intake im going to use the tpi throttle body on this new intake to keep it a very simple bolt on deal, not to mention upgraded tpi tb's are cheap

the combo

3.0L v6
11.03-1 cr
custom solid roller cam 278/268 on 114lsa .550/.550 lift
ported heads
85# injectors
e-85 for fuel
70mm turbo for dyno tuning, switching to the bw s475 after

 

I for one cant wait.......
Great work

 

dyno is in 3 days woot

 

How much you going to sell these for if the numbers are good?

 

im not sure yet with the amount of pm's i have goten about them i will never be able to keep up with the orders, so i have been contacting some places to see if i cant farm out the machining work to make this easier to do and get the costs down

im giong to shoot for 350/400 for manifold alone, and 575/625 as a bolt on kit intake/fuel rails, fuel line/ return and afpr


depending on some prices i get back they may be cheaper

 

So how did everything go????
Numbers pictures anything

 

 

sorry guys i just moved back to iowa and dont have internet ill post a new thread in a few mins with results

 

Subscribing... too bad redraif is not around. Put your intake on that car and you could have had ported stocker vs. truleo vs. yours... all on the same car back to back to back.

That would make for an interesting comparison...

Can't wait for dyno results... I still gotta pin down an intake for mine... unless I go hybrid... Any plans to make a hybrid version?
