Gruppe-M Ram Air System Installed - Page 4

What are you impressions of the kit? How is driveability, power, etc?

***NitrousG35*** · 03-16-2008, 11:32 PM

OP, can you give us a shot of the wiper cowl up close from side to side? I am not seeing the little holes that the USDM wiper cowl has. How does the new wiper cowl get intake air for the ventilation?

Good question Bill.

OP, a big favor: Can you tell us how you ordered this and how you relocated the brake reservoir?

Ultimately I think you'll find that no intake will provide hp/tq gains beyond 10-15hp. I would suggest running an Injen CAI and saving your money until a cost efficient tuneable option becomes available for the K20Z3. My .02 cents.

Doh! I meant Gruppe M.

Also, this is by Gruppe M, not Mugen. Mugen's setup looks similar to the Comptech Icebox.

it's a nice concept but how much power can you really get from an intake , $1200.00 is a lot of money props for being the 1st but it's too rich for me .

True, but that intake is just sex. IF it were a a car show, it would take best engine bay over any intake on the market currently for us now anyday.

Even if it was a gain of +17-20 hp. Is +5 hp really worth $800. It's more of a showcar type of mod.

Quick Q
Are you throwing any Cels?

strCIVIC · 03-16-2008, 11:53 PM

nice....

You have to look at this in terms of a total package. If you have a race header, cat-back, cams and Hondata, then yes, this will certainly make more power. A motor with better breathing and cam lift/duration will need cooler, denser and more air. This intake does all that.

no one knows the gains on this yet, plus you will never know the gains on it untill you incorporate an windtunnel with a dyno. Is an intake worth that much to me, no. But thats just me. If i had all the money in the world, sure why not.

This is such a good point. You can't dyno a car with ram air. Ram air operates on air velocity and pressure. Thus, the faster you go, the greater the ram effect. In a sense, it is a simple form of supercharging sans the blower. As you so well noted, a wind tunnel would be needed to measure the air pressure via transducers at the wiper cowl area.

In the thread I did on cowl induction, the Miata group that did the cowl induction install used acceleration and passing tests as the real evaluation of using air from this high pressure zone. They found 0-60 times dropped .5 seconds, which is really quite substantial.

you wont get a cel from this.

.jrmyrmx · 03-17-2008, 12:04 AM

i was gonna get this but was afraid it wouldnt fit..props for taking the dive, glad it works, i may get one now

ViperSam · 03-17-2008, 12:25 AM

WOW! That looks REALLY good! Will this work on both the K20 and R18?

So expensive, but what a bad ass intake..
Q. What if you would dyno the car with one of those super blower, big ass metal fans right in front of the car to more or less simulating the effect of the air rushing in?

K20 SDN · 03-17-2008, 12:26 AM

I was thinking of dynoing the car with the hole plugged off... and doing it open...

but even then... the car isn't even moving so its hard to judge how much power it gives u. But i know from how the car feels driving.. its seems like it works well. I also installed the Spoon Venturi Throttle Body and the Hondata manifold gasket. Very good combo.

I cant wait to put the rest of the Mods!!
