injen cai vs mugen airbox

[Noel]

Isn't that always the case?

While the derived tuning power curve is different from an airbox/CAI/SRI, it's application usage that will truly see which matches best.

An airbox is extremely great for response and constant out of powerband usage however there is minimal top end rewards. While a CAI/SRI in constant VTEC powerband will execute and deliver optimum results not useful when hopping in and out of VTEC.

There isn't a "correct/ultimate/perfect" school of tuning and managing powerband distribution especially on VTEC engines. You either have the low to mid or mid to high powerband.

Food for thought to wrap up the week - How many people have the budget and endless passion to pursuit total balance?

i guess doing it in the evening with poor lighting doesn't help. it took me ages to locate all the screws to remove, then to figure out how to remove the base. didn;t realise there was a bolt to be undone, UNDER the filter element!

haha ownt for unscrewing the 12 or so screws

that's not completely true jingers. throughout this discussion i have noted on more than one occasion that i believe the gruppem intake is the best intake for the DC5.

and i hope no one assumes that my motive in discussion is solely to defend the choice i made when i chose my intake because i held these views after much research was conducted on all intakes well before i purchased an intake. in fact i had an SRI installed for some time before i moved on to bigger and better things.

Yeh i realise that sang, maybe i should have wrote "most" people.

So after reading the post do we conclude that certain intakes are better at certain things and all have pro's and cons. Its up to the user to decide which intake suits there driving style whether its for response on a track or outright top-end power for straight line [Boring crap] racing.

My choice out of Mugen and Injen like the topic states would be MUGEN cos I track the car and need more of a flat torque curve and maximum response intake system.

gruppe M is great.... when changing from a top fuel SRI (prob one of the better designed SRIs) there was a whole heap of difference even before ECU tuning

[AUDM DC5R]

Has there ever been a dyno graph which shows how much power each intake [Mugen, Injen and Gruppe M] produce on a Stock ITR?

If people have any it would be good to post them up in this forum!

dyno wouldnt be accurate in the case of mugen and gruppem as has been discussed already.

Here is a shot of my grill mods for the Mugen Airbox with std bumper. The main reason for my mod was to improve the quality of the air the box was seeing. IAT is still higher than I saw with the Injen but overall I'm happy.

[Jingers]

nice engine bay. what radiator shroud cover are you using?

[noodleman]

looks like a cf print sticker

[nzitr]

The shroud is one I made myself from a sheet of cf. It slots in behind the badge/grill horizontal bar and sits quite nicely. With the bonnet closed I easily get my hand into the Mugen scoop.

It's the camera flash that makes it look a little fake.

[Jingers]

it looks quite nice actually

[matt]

interesting discussion

NZITR-do you have a pic of your grill from the front?

Noel-why do the japanese race cars have to use airboxes?

[Jingers]

it could be becuase of certin class restrictions. but yes, i have not seen any demo cars use injen or aem. This could also be a distrubution issue.

With so much good brands in jap why would you bother importing other brands?

[Noel]

Matt - Jing is correct in reference to racing restrictions. Further elaboration - Not permitted to make significant air intake modifications. Hence the airbox design theory. Cars that aren't used for restricted racing have unlimited design cues and won't be spotting airbox designs.
