See and Hear GruppeM Intake on video

VIDEO link: http://www.metacafe.com/watch/197160...2006_bmw_330i/

Dyno test and GruppeM Intake were purchased at:
Technik Engineering
13428 Beach Ave

Marina Del Rey, CA 90292
contact: Mike @ 310.306.4060

I had a baseline dyno test done today to account for rear tire diameter changes (slight increase), and to factor out ambient temperature differences from the first dyno test outcome.

This time, baseline max wheel HP = 210.37
After intake mod., max wheel HP = 215.87 (+5.5)

At slightly above 6500 rpm, the before and after mod difference was 8.5 wHP. In fact, HP and torque increased across practically all rpm ranges. At around 2850 rpm, the torque improvement was around 9-10 ft-lbs at the wheel. Differences at the flywheel would certainly be greater.

I hate to admit this, but I was running on near 11,000 miles worth of dirty oil. After today, it's even dirtier. I can't help but wonder how better lubrication may have helped.

I know you're kidding, but in all seriousness, as much as I am for saving weight, I'm afraid that switching to a CF hood or trunk would mess up the crumple zone, and make an accident a little more dangerous.

Months ago, longtran mentioned I could place the camera between the rear headrest and seat. Well it worked!

It's hard to place a value of worth when it comes to cars and modding. We pay a large amount of money for a small amount of improvement. When I drove the car for the first time after adding the intake, I immediately noticed the change in sound. I have the OEM exhaust, so I was a bit surprised with how it made a noticeably nice, deep droning sound, especially around 2600-3400 rpm. It was as if I were driving within a parking garage without all the echoing. At just above 3000 rpm, I could hear a subtle air sucking sound from the intake. As for my butt dyno, the car seems to be more responsive at any given speed--this is more noticeable when driving "normally" out of the engine's powerband, say at around 2500-3500 rpm. When I downshift (as if to maximize power), then floor the throttle it's hard to tell because the car always makes noise and goes "fast" under those circumstances.

Michael, great looking intake and sounds terrific also! Thanks for sharing.

Anyone interested in hearing how it sounds from the outside:

Another informative post Frogster! I removed my intake because the noise was getting annoying. My car feels better with the stock intake lol. The Group M intake resembles the OEM intake just with Carbon fiber box and a better High/flow filter. How many dyno runs did you guys do with the intake and without? I am assuming is was multiple on both and you took the lowest stock numbers/ highest intake numbers.

Hi Ryan,

I had 3 dyno runs before and 3 runs after install. We used the best of 3 on each so the comparison would not be skewed.

I've been watching my gas mileage go from 22 to 21 to 20 to 19 and now 18.9. I suspect my oil has lost some of its viscosity, but I'm going to change it tonight and see what happens. So unlike me to go this long without an oil change, but I've been too busy posting on this forum.

Did you do a break-in oil change? I need to change my oil B4 the meet.

The intake noise is a bit loud at around 2600 to 3200 rpm. A part of me likes this, and a part of me is a little annoyed. Does that make sense? Sounds like the vacuum cleaner motor when it's sucking down on the carpet too well.

The car does seem to go quicker and more easily with only slight throttle pressure than it did before. I talked to Mike at Technik about my butt dyno given the dyno results, and he didn't think I was imagining the difference.

I liked the 3-4RPM growl at first but I it got on my nerves because the car made too much noise at low speeds. I was running an open filter I would assume the Carbon Fiber box would drown out a bit of that noise and make more tolerable.
