************************************************** ****

Look what I've finally finished (chipping away at 20mins a week since August :doubt: ). This is psychotic.

Left in "D", the car revs to 7000rpm and is just starting to taper off. Idle is 700rpm, fuel econ is down to 9.7L/100km - down near 0.5L - and I'm not driving it easily :D

Pulls VERY hard from 3000 to 6000rpm. Not too amazing below that - just very smooth.

This afternoon it chirped from 1st to 2nd on bitumen with me and Dad (=200kg) in the car with tiptronic shifting. Has a SPRINTEX SC AWD chirped with 17's on yet??

I know, I'm still running my old pod box from last year. I'll put a new one in one day when I get time :coffee:
The manifold will be painted now that I know it works. In future they will be made from stainless - not mild steel as mine is atm. The entire internal surface has been coated with POR15 rust preventative paint (Google it).

I don't even have headers on my car yet. Maybe this thursday I'll get around to them.:bowrofl:

Going to put it on my Mrs TF 3L manual and do before and after dyno runs in the new year to support my experience.

Those of you with keen eyes can see that it's twin TB ready too!

Pics:
1) Shows removable end-plate for 2nd TB
2) Please ignore the colour scheme - I hate it too
3) Looks like Freddy Kruegers fingers hey?
4) It's huge - but it still fits neatly.

Who do i have to kill to get one of these?

Me wants too. How does it sound? any different?

i want to have that intake's babies!!

im with delphia...

:thumbsup:

i'd want that badboy in my stocking for christmas... *please santa* :pray:

I spoke first, and I swear if anyone tries to cut me out of the 2nd gen prototype. Im going to need crutches. I wont be able to hop everywhere when i break my foot off in their ass :D

Me wants too. How does it sound? any different?Sounds vicious. With the hood up, you can hear each inlet pulse shooting down the runners. Bonnet down I can't hear much over my 3" exhaust. With my window down from 3000rpm onwards there's this noise like a jet engine building thrust. It's like a whistle sort of but not quite. It's pretty cool actually.

I'm finally feeling confident about taking it down the Qrt Mile now.

Driving around for the last 2 days has left me with a sore face: I haven't smiled this much since I got my 1st blow job in highschool - that was last century!

I used the square channel 'cause it was on-hand and presented an enormous plenum volume, while making the runner joining simple(r) than on a curved surface.

Where does you torque start to really kick in on your model? Got any pics? I'm thinking using even smaller runners (not too much smaller) to get more low rpm torque - keeping the length.

Throttle response from a standing start is insane!!

Nathan on NMC has been in the car on thursday, like to hear his opinions now that he's stopped grining like a fool ;)

Looks fantastic, cant wait to see it and hear it. I'm in line.

I,ll be going to see EZ next week and might get a ride in it, donating my car also for a dyno run with the plenum on so you all know how much more power a 3.5l will make.

Looks like a monster Ian!! Any plans for a production run in future??

I thought that you were up to no good with intake manifolds when I saw your avatar - very impressive! Any chance of a production run? (oooh deja vu!)

Cheers
Heath Young

Nice work, M8! :thumbsup:

:bowrofl:

woot ! r you planning on selling these? i will definetly buy one if you are. I'm so glad someone out there with some know how is making us good stuff for our magna's, with more than just a dollar figure in mind

keep up the excellent work !

oh yeah and can you please tell me how much (if you plan to make a couple more) ? thanks


later :cool:

curious EZY.... is this with the standard ecu not even piggy backed?

also GREAT WORK, i think ur well on ur way to ur first million bucks if u keep producing the way u are hehe :P

will donate my second gen 2.6 manual as a test mule for the astron 2 model.
have you considerd using the other end with another throttle on it? that would be CRAZY!! :P

Looks great, Ian. Wonder how it would fit with a strut brace in place?

lol I still am :D .

It's deffernetly a different feeling, I was suprised to feel the difference that this actually made it even amazed my best mate who was with us and he's a ford nut. Be warned expect to be thrown back into your seat those who go for a ride. :badgrin:
I can't wait for it to be tested on a manual sports or VRX.

EZYBOY let me know when you do the dyno I'd love to see how it goes.

Cheers,

Nathan.

looks kinda scary...... but top marks for effort!!!

but does it allow for fitment of a strut brace? and what other mods are needed for this to be applied (cams? ecu? larger tb?) or can it be installed as a standalone? and finally.......... approx price?

All I can say is Hell Efen Yeah!

Wow guys, thanks for the positive feedback.

This was just a test mule, so CHEAP was the word for construction. My production units will be fully stainless and TIG welded.

I'm still running STOCK ECU, with a flowed TB, K&N pod, pod box (a very obsolete one at that), cold air intake. I still have stock exhaust manifolds and cat atm, but 3" cat-back.

The stock ECU has responded flawlessly. I have no FPR or insulation gaskets atm. I do have a hot water bypass of the TB and the EGR is disabled. The gearbox and drivetrain EASILY handles this power boost. I think it actually enjoys it. ;)

I am aiming for production. Expect the cost to be around the $1000 mark but don't quote me on that. Kit will aim to include insulated gaskets etc.

This particular plenum doesn't leave enuf room for a strut brace, but subsequent redesign may make this possible.

As for the 2nd TB, it is designed to sit on the driver's side of the plenum but we think there'll be intake resonance disruptions to air flow so we're having a think-tank about internal baffling etc.

By using long thin runners we achieve a high intake air flow velocity, shorter length runners will move the start of the torque curve higher into the rev range, as will larger diameter pipes. We've used twin long, thinner than stock runners to achieve a much higher inlet velocity as well as outflow the stock runners by 20-25% per cylinder. The square plenum actually assists runner resonance by reflecting the pulses back down the runners and increasing the air speed down the runner.

Many thanks to the Honda and Ferrari Formula 1 development websites for their input in this project.

Looks Great - Cant wait to see the final production model sitting in my engine bay :D :D - eventually :doubt: :doubt:

Looks like a great design mate!

looks awesome mate!!! well done!

oh and SHOTGUN your cheap one :P

put me down for one when they r in production :D

hypothetically, if u got a great gain in an AWD then FWD should get even for gain correct? ... cos AWD has so much drive train loss? ...

i really cant wait till u get these inot productuon:D ur starting to have as many products as rpW and cost a fraction the price:P lol

hypothetically, if u got a great gain in an AWD then FWD should get even for gain correct? ... cos AWD has so much drive train loss? ... The weight and drivertrain loss are significant, but provide other advantages.

Forgot to mention too that my fuel economy has also improved! My average run to work gets me 10.6L/100 atm, last friday I got 9.7L/100 with the aircon on all the way. The instant fuel figure at 80km on flat road was 8.2L/100. Average trip speed was 52.5km.


ur starting to have as many products as rpW and cost a fraction the price:P lolWhile the comparison is obvious, I really can't compete on development budget or staff numbers. We'll just try to do what we do well. We're competitive on price because our overheads are low and we manufacture what we sell, not just onsell someone else's hard work.

That'd give me more sleep at night thou :think:

Took a mate for a fang in my Magna today before heading to Newy and when we were turning around on Raymond Terrace Rd, I gunned it on the gravel to beat the oncoming traffic and the back end hooked out :shock: :naughty: . Got some looks from the occupants of the falcon coming towards us! I'd never seen a Magna hook it's a*se out either.

top job m8 looks mean wen u open the hood. could'nt agree more on wat was said previously:thumbsup:

just a question ez boy why did you use 12 runners and not just 6 runners in a bigger diameter


how hard would it to make this??

and what would you think of this design

He explained that 12 thin runners increases the veloicty of the intake... kinda like the exhaust back pressure thing... Complicated to explain but makes sense if you 'get it'.

As for a twin MAF design, nigh on impossible without a LOT of computer work to take both air intake readings and average them out before sending to the ECU. easier to run twin TB's with a single MAF.

As for internal baffling on the current design, it 'might be possible to run the bottom 6 runners off of one side and the top 6 off the other?

Can i have a look at the calculations EZ Boy?

It would be an aftermarket ECU job for sure, and in which case you would just use a MAP or a 300zx MAF which is much larger.

Forget about twin MAFs, in the too-hard/waste of time basket for a natch asp motor. The larger the pipe diameter used, the slower the air flow. Short runners, large pipe diameters and large plenums all favour high rpm power generation. Long runners, small pipes and smaller plenums have low/mid rpm peak power generation. So from what we've learnt from this prototype and the next one on the board we should be able to supply a custom intake manifold to cater for the INDIVIDUAL'S DESIRED POWER/REV RANGE (in consideration of other modifications to the engine, gearbox, vehicle use etc).

I've been mulling over the twin TB for a LONG time. I like the flow advantages of your illustration, however I am trying to avoid using 2x OEM TB's due to cost and scarcity (imagine if everyone on AMC started buying up spare TB's!!). This presents several problems. By splitting the plenums idle control becomes difficult, cruise control and Traction control is forfeited, linkage alignment etc issues.

By putting a TB on each end of a plenum is expected to create a vacuum bias to the TB closed the main air inlet (i.e. air will take the shortest direct route everytime). A 2nd TB directly opposite another open TB may let air pass straight THRU the other TB or create resonance disturbances to the incoming air flow. We have several baffle ideas to overcome this but are leaning now towards a side-by-side twin TB arrangement on the same end of the plenum sharing a common custom butterfly shaft. This allows the use of the OEM idle mmt, TPS, Cruise and TCL. Still on the drawing board.

We haven't done any hard and fast calculations to support the results we achieved. I am trying to book dyno time for next thursday with my TF manual as the test mule.

/me does the happydance around EZ Boy

Holllllllyyyyyyy chit. How sweet would that look in stainless or gold chrome, drool slobber.
Even TC likes it :D

Hang on, mines a four pot. :rant: :rant: :)

might be worth looking at a throttle body off a f150 or f250 as they are a joint twin !!?

nice man maybe theirs hope for somone like me and the plenum porting problems for 1st gens as we talked about

For sure - anything with runners is a potential victim!

F-series trucks - which motors? Dad's a ford nut, he should've mentioned it to me by now :rant:

efi winsor motors, 302ci
i dont remember them being very large.

any more news on this?:D

from what i read, u say u got a noticable gain from this, and u dont have extractors, and have complete standard ecu .....so would it be fair to say if hypothetically u put this manifold on a FWD ( less drive train loss ) with extractors cai flowed/bored TB and had a piggy back tuned , that it would make quite a considerable gain? ...

LATEST NEWS:

Dyno run looking good for next wk unless the Mrs goes into labour :shock: She's due on the Tuesday!!

We've made a number of design changes that will be integrated into a new prototype. This will comprise a smaller plenum, smaller diameter inlet runners (still dual runners per port), internal fins to maintain and stabilise airflow into the lower inlet manifold and inlet valves, improved runner inlet trumpets, and posibly some internal plenum baffling.

Why?

Because I want to offer several manifold versions. The first version helps the high rpm, I now want something to make everyday low-mid driving more enjoyable esp for the AWD's and auto's.

Still lots of R&D but we're having fun!

geez! get ya priorities right! you dont HAVE to be there do you? :bowrofl:

nah congrats mate! looking forward to positive results from both activities :D

rofl! you need a roboit guy like on that beer add :D

U gonna make one for th e 4 cyl's some time. It looks sweet 2 bad i got carbie 4 cyl 2nd gen i should wait a long while, but if u need a test dummy i'm it :).

90s mod f 150 - f 250 302 efi

twin throttle body far as i rember there fairly big

U gonna make one for th e 4 cyl's some time. It looks sweet 2 bad i got carbie 4 cyl 2nd gen i should wait a long while, but if u need a test dummy i'm it :).

dood u need to upgrade to EFI!!

i know :cry:

But i cant be stuffed doing the change over myself and i cant afford to get it done, i'm so lazy lol

Approx how much would it cost to get done, someones offered to give me the wires and computer and jets etc.., how much for just the install

Sorry for going off topic, i just want one so bad :cry: (i know its for the 6 cyls, but still efi should help me)

i think this has been done in the 1st gen section, carbie to EFI, and theres a whole tutorial etc, check out that section :)

/end thread hijack

man i cant wait for the 2nd gen...
