Gruppe-M purchase! & review w/ pics

[XP02ED]

i heard u cant dyno a gruppem to see the exact output..

anywaiz no use dyno at this time cars are stock.. hopefully my cams and hondata come soon

You can dyno to measure the gain in power (which is what makes your car accelerate harder). But you cannot dyno for throttle response, which is the main benefit of the GruppeM over the CAI-type intakes.

very nice....

that is correct to some extent, a dyno pull will show that the gruppeM has gains over the OEM airbox, this is obvious.... however, the gruppeM intake works on the concept of extracting air from a low pressure pocket which equates to lower intake air temperature... a dyno pull cannot replica this situation... so i guess someone could use the dyno pull to figure out the most minimum gain from the intake???

Low pressure pocket = low air density though...

[Mst_Mugen]

Low pressure pocket = low air density though...

sorry man... but low pressure pocket does not equal low air density, its the opposite... as a general basis, the lower the air pressure, means the lower the air temperature, which means the more dense the air is... which therefore means: extracting air from a low pressure pocket = extracting air that is colder than ambient which will equate to more air molecules filling up the cylinder = a bigger combustion

which brings me back to my original point, the full potential power output of a gruppeM can only be reached while the car is in motion

you guys should date! LOL

Im getting my GruppeM under 800 that rocks

Are you telling me that your GruppeM is able to create a low temperature pocket just in front of your windscreen? The reason why the GruppeM has good gains is because the stock DC5 intake is located right next to the engine and gets warmed up very easily.

The reason why you don't see the gains on the dyno is because the fan is blowing into your front bar and not at your windscreen!

the GruppeM intake draw air from the windscreen and that is where they found to be of lowest air temp. that's what they claim

sorry man?? i dont quite understand wat ur tryin to say??? the gruppeM has exactly the same mounting points as the OEM airbox, meaning its in the same location... the only difference is the material incorporated in the design and the position in which air is extracted... LOL, u know wat, it doesnt even matter... GRUPPEM IS KING, ALL OTHER INTAKES ARE POO!! *flame suit on*

[bennjamin]

the only way on paper to tell if a mod works is to put the car on the dyno with a "before and after" comparison. Including sensor readouts for IAT , CO2 etc too.
Everything else is up to the driver to judge ( throttle response etc etc etc)

There will be someone with dyno sheet soon as I believe more than 10 people are buying gruppem intake due to the price.
