Well so I got the scoops and they look all pretty and all but I seriously doubt they do anything for performance.

One reason being the area where it "feeds" into the intake tube overlaps the intake and has about 0.5" gap plus in some area so any +ve pressure built up here just escapes down the gaps ... I will look to either form the back end of the scoop to mate better to the inlet or add foam type surround to provide a seal... or mbe just sell them.

So, seriously, dont be under any illuision these add any power at all.

Toadster

do you think the pressure will escape around the big sucking hole? there have been some #'s measured on these...

https://mbworld.org/forums/w211-amg/...ty-review.html

just some basic data breakdown here - looks like 4-4.5% increase in volume, and reduces pressure by .5

before:
MAF 1.10 - 56.70
MAP 10.55 - 381.41
Press. 5.91 - 54.93

after:
MAF 1.24 - 59.45
MAP 12.27 - 398.28
Press. 5.91 - 54.63

MAF increase 4.63%
MAP increase 4.24%
Press diff: .55% reduction

at speed, it's noticeable that these have been installed - the M5 guys have seen up to 2 tenths in the 1/4 mile with scoops

Ram intake systems work very well on F1 cars and bikes.

Not sure how much of a ram effect the scoops can create.

Even if they do have an effect, will come at high speeds and one can never really tell if there actually is any difference. I have the RPI scoops on my M6 and can't tell if there is any difference at any speed.

The only sucking hole around here is you.

The TTM "scoops" won't do anything for the car. that area under the hood is a High Pressure zone long before the "Scoops" were added.

+ 1

Agree 1000%.

AMGPilot

And those ram systems are sealed, ours not so much. Everyone keeps forgetting about the water drains built into our Airboxes....

Hasan Shaikh

Its not only that. The rams on bikes and F1 cars are located outside the engine compartment, which makes a big difference.

I think you can seal the air boxes easily. For the BMWs RPI has small metal plates that can be used to seal off the air boxes.

thanks for sharing

Of course it willl blast past the "sucking hole" ... if the hole needs to suck its not exactly creating +ve pressure. It needs to be sealed otherwise there is no point to these things.

The way they designed at mom the only thing being pressurised (at the very best) is the engine compartment.....

I cant believe the fitment on these is just so rediculously thought out. 2 10's in qtr mile on these is just not happening.

SLR has proper ram system ...its perfectly sealed, and works - and so does the M5 for that matter one of the reasons it does so well at high speed.

The "ram air effect" on cars and bikes is a myth. You can create some minor gains by changing the inlet location to breathe cooler air but you will never see compression at subsonic speeds.

These products are a joke.

stevebez

Well if thats the case then so is a large air box, fat intake tubes and possibly throttle body as they are all part of the same linear system? I am still very scepticle on the airbox and intake tubes, the TB makes sense as its the bIggest (smallest) restriction in the loop...

I would guess having a ram type feed would do harm. Creating a +ve pressure on the outside of an airfilter should help, albeit marginal. The SLR system is interesting but perhaps designed more for cool air than ram as you say...

Celicasaur

I have to ask.....what's the consensus on routing a single inlet pipe with a cone filter squeezed into the gap where the ttm scoops would otherwise sit?

I don't think anyone ever claimed these add "Noticable power" i have heard people say top end feels better but i also don't belive you will "Feel" the diffrence after installed. Im getting them to go along with my Beast tubes to finsh intake part.

AgSilver

F1's, LMP's, etc utilize a venturi effect which actually accelerates the airflow and drops the temperature of the air. Not a particularly new technology, but it continues to be refined for particular applications. Look at an old Weber or even a new Holley. They all use this technology. Oh, and you can replace the stock driver side intake which has a significant restriction with a stock right side tube for about $15. It's all the little things.

AMGPilot

Sorry but incorrect. In order to accelerate the airflow you have to compress it (bernoulli's principal) which in turn heats the air


The Venturi you are speaking of in lmp cars is the restrictor. The reasson they have such large Airboxes is to store enough air that the motor doesn't starve on tip in.

I personally never was, but everyone was all excited so I didn't wanna start any arguments or burst any bubbles. lol

Last night, I dreamt the e55 was able to hit 200mph thanks to the TTM scoops.

Yes, I have problems.

Shifter

What water drains? I've never seen them.

AMGPilot

Look at the bottom of your airbox

Not expecting anything in terms of power so I will not be disappointed if I do not realize any gains;more for the aesthetic appeal for me, and anything above that will be gravy.

Toadster

more available air to suck in = more power
reducing the pressure needed to suck = free horsepower (i.e. less strain to induce air)

honestly, I doubted it - but at speed, the car has more power

AMGPilot

sorry but no, they don't do anything but make your wallet lighter.

easy test, get yourself a pressure differential gauge and put the pre-probe at the snorkel entrance. Put the post-probe at the back of the airbox above the filter. There is no difference.

You are hearing more intake noise, for you to "Feel" more power up top you need to make 20+hp and those don't do anything

dchl21

i dont think it works, im wont pay for a new set, but ill buy them used because they look beautiful.
