OFFICIAL INTAKE MANIFOLD FLOWBENCH TEST RESULTS

[monster007]

Soon 

[Jeronkie]

  phenomenal! 

[Don®]

Reason why ABD has made satisfactory results is do to its short, wide and stuby runner design. I'd like to point out that it's overall performance would not be as expected.

Trq in the mid-range would suffer and fuel atomization would be less than opitmal as a result from low port velocity and turbulent flow.

[badger5]

some great results and information folks.. thankyou.
To 2nd (not that he needs it) jimmys monstor 007 largeport with r32 throttle body works a treat giving me a 32bhp/22lbft gain over my previous dual plenum largeport mani on std tbody.

works well...

517bhp so far

monster, could you post your reply to the APR employee comment in here since vortex won't let you?

[silvercar]

monster, could you post your reply to the APR employee comment in here since vortex won't let you?

I would like to challenge him to register over here.

Jimmy:  while i agree that the taper is better, Dont you think that your water test was exaggerated a bit by gravity?

Yeah, gravity is skewing it but it was only done to give you an exagerated visual.

[VariantStg3]

Alright I'll admit it. I don't know who's who here.

Don R is one who designed the?

Monster007 is the one who designed the?

Or did you both work together on one manifold?

Sorry for not knowing

[Dizzy]

They worked together to design, monster built while Don oversaw and added influence along the way.  Make him an offer he can't refuse.     Anyone care about runner length?

DonR helped Monster design it but Monster built them all...IIRC

Thanks for the info. I hate when I am on a roll waxing poetic and all, then the Law comes along and destroys it. It always seems to happen when I am having the most fun.

Welcome to Stu Cazzo.     I understand the concept of intake resonant tuning, treating the entire intake port and runner as one "inlet" to the valves, and reaping the benefits of the cycles of repeated resonant frequencies.  Slappynuts however overvalues this aspect.  This is because this is used to shift the peak torque around as well as tune for a specific rpm range.  1.8t's don't turn crazy rpms and the biggest reason that resonant tuning isn't all that on a turbo motor is b/c the torque curve is more dictated by flow of the turbo then the head, not the intake manifold.    That says to me have an intake mani that'll outflow your head and you're golden.   Yes, don't run the most humongous intake possible, but rather one that complements your flow goal (desired HP).   Like IC piping, the largest size needed that maintains the highest velocity without exceeding general drag limits. 

[HYPERTUNE]

Hi Guys,

Firstly, I have to congratulate all involved on an awesome job getting all of this data together. It's rare that people are prepared to put in so much effort and share the information freely. The members of elitedubs should consider themselves lucky   

Now, I don't intend to come here and advertise my own product, but I would like to comment on the following statement made in the original post:

Hypertune  Retail price is $1399
When i pulled this out of the box, Dan smiled real big and said "Bling, bling."  Again, they thought the machine work on this was phenomonal. and that the injector mounting was great.  But they absolutely hated the plenum.  They said it was far too thin for a big boost, big power or sprayed car. Dave said one good pop back through the intake would blow it to pieces, and then remarked on a flaw in the weld on the inside of the plenum.

Well, thanks for the comments regarding the machining. It's certainly not the most cost effective way to make an inlet manifold, but that's the way we would like it on our own cars, so that's what we offer our customers.

Regarding the thickness and strength of the plenum, we have never had any problems so far. In fact, exactly the same material and thickness is used for our RB26 manifolds and these have a much larger surface area and therefore would be more succeptable to deformation or being "blown to pieces". Please note that we have many customers using our manifolds and running big boost.

Here is a video of one of them. TURN UP THE VOLUME !!!!

Mark, I really appreciate you replying here. The hypertune manifold is a beautiful piece and showed great results  ...Please, you are welcome to join in on this discussion at your leisure 

Thanks!

[badger5]

Was going to reply, but don't plan in getting into a pissing match. So there fire extinguisher on toilet rolls rules
And why is the pix of the Audi a duel plenum?

quite... R8 example used by APR is dual plenum.... as I have reminded him - that said those engines are running intake restrictors so the dynamics of their total system are not going to be the same as us lot running as big as we like.
Lehmann was designed for this kind of turbo restrictor motorsport I believe.

[VariantStg3]

But is the design Brett/APR came up with Good? We keep bashing about and not really getting to the heart of why the test was done.

I think most people want to be able to conclude some things with this test, so what can we conclude?

I see it this way. A consumer today, as long as they are will to port there head to the AEB style intake ports has 4 options (RMR, APR, Hypertune, and 007 LP) avaiable to them that should make substantial improvements in power.

There is also a way to configure a stock set of AEB runners to improve flow as well, but it will take some fabrication skills to keep the cost down. A do-it-yourselfer could build the HomeBrew mani for right aroung $225. (Footnote: If you can't weld aluminum add $200.00 to the cost making it $425.00

Finally for straight Bolt on performance improvement the hands down WINNER is the 007 SP unit. You can in a about an hour bolt on this unit and increase the available air to the head significantly (194CFM) and also balance the runner better. IMHO this 007SP intake would be an exellent upgrade for K04 upgrade cars.

A few of the designs that seemed unortodox in look turned out to also have lower flowbench numbers. As the great Frank Lloyd Wright said as often as possible, "Form follows Function."

[GTIguy20v]

Here's just a thought...I really like the RMR mani because it seems great for upgrading and changing your set up.  You can change which side the TB is on, and also has provisions for a large array of TB sizes and types.  (007 is definitely exceptional if you never change your set up much.)

[badger5]

one of thew things which pi$$es me off about certain braggers/tuners is "ours will out perform anyones" type boast.  Big words and a world of drivvle and misdirection to go read books to be as "educated" as them type BS... get a life, and accept there are other products which may in fact be the equal, or dare I suggest "better" than theirs!  oh yes, really.

Sad folk that they are in their arrogance.

Quoting 37whp from their manifold for example (APR) is more than misleading as the actual modifications were porting a head to largeport as well as bolting on a bigger manifold... QED more power was gained on that setup with tuning than before.... BUT 2 significant things changed.  Port size on head! as well as 75mm throttle body on intake manifold.

{rant over}

 

[transient]

well.. if you can wait a few months (like 6 or so) I'll have a large port motor with a 007 mani and s4 throttle body.. if I can find a cheap apr manifold, I'd be more than happy to do the back-to-back dyno comparison...

[Loxias]

Nice test guys!
It's really nice to see 007 is the winner on this,since its installed in my car and running perfectly.Just wait for the results!

[spoolin turbo s]

Monter 007,

you have an intake manifold in the works that would provide a gain in the 4500-7500rpm range?

it would be awesome if you did....I think it would sell well for BT guys

The Intake does provide that type of power. I mentioned this before - the stock Small Port head is now a restriction not the 007 SP intake manifold.

[CapeGLS]

This is fantastic!

[BigAl03GTI]

  I CAN SAY THAT I WAS  thinking of going with ross racings intake manifold until i saw these results.  excellent work

[Dizzy]

This is fantastic!

You ain't seen nothing yet.   

[VariantStg3]

I hope so. It looks like I am going to have to go away from my liquid to air setup next year, as SFWD is not allowing them unless they're stock to the car. So I am going to need a new Intercooler(800HP) and a Manifold.... of excellent reputation.

[vgtiw18t]

so is there any news on a racing version(if there is such a thing) of the 007 large port?

[badger5]

watch out early in 2008 for a very good flowing manifold to appear from a very reputable source.
007 mani was great, but try getting hold of one 

[Vegard]

I would go for something more like this one for higher outputs.

[STR8E180]

i only just came across this forum now and since its on the subject of inlet manifolds and im just about to start tig welding mine together i thought i would post up my design and see wat u guys think about it

the inlet manifold is for a SR20DET with a SR20VET cylinder head so its kinda a hybrid engine
its VVL cylinder head so it changes duration and lift and its also turbo charged with a turbonetics GT-K 500

basically wat ive done is machined down the standard inlet manifold for the flange plate and injector boss

im making the plenum and runners in 2 different pieces so i can unbolt the plenum from the runners for cleaning, servicing and trying other plenum designs to see wat works best

also keep in mind i dont have a CNC machine and im not willing to fork out money to hire a CNC machine and programing for a one of item it just isnt worth it in my eyes so im doing the best i can with out a cnc machine
