Cmon Im sure this can get done if the car is left there for a few days. Im sure a having the car there would be a big benefit. Whats it gonna take to get this done? Does someone need gas money or me to pay them for the day to drive over there? Shit if you get this done and the it comes out that the gains are simaler to the Ms this will be golden for us all, these cars have no aftermarket, if this pans out and the intrest is there Eloy wont forget about us in the future. Im in Ma if I had to drive 4 hours or more out of my way and take a sick day or a vacation day I would to get it done. Its well worth it IMHO

I'd be willing to do it; but, there is no way I can drive the 1.5 hr up spend a few days probably on the street outside of RPI to get the R&D done. If it can be done in a day I'm up for it.

Maybe the RPI scoop could work on non-M's after all (?). There's an interesting writeup on Z4-forum http://www.z4-forum.com/forum/viewtopic.php?f=2&t=3324 in which the installation of the Dinan scoop is discussed. It apparently involves removing the diagonal crossmember that caused the interference in mandizzle's installation attempt. Dinan just replaces the crossmember with a vertical piece that doesn't interfere (nicely pictured in the linked post). It seems to me that if RPI did a similar replacement of the crossmember they might be able to just fit the existing scoop on non-M's.

Would Eloy care to comment on whether this is possible?

Dammmittt · 03-04-2008, 10:52 AM

I dunno. Modifying OE structural parts probably isn't something that RPI wants to get into. If you guys wanted to make that leap on your own it would be cool to see a write up about it the DIY section

vachss · 03-04-2008, 11:31 AM

Hey, If Dinan does it then it has to be safe, right....?

BimmerZealot · 03-04-2008, 11:44 AM

If RPI is up for it I'll be a test mule

You can take solice in the fact that Dinan maintains factory warranty.

And not just Dinan, but there are many companies that replace the stock firewall braces for a stronger metal bar.

I'm pretty sure none of these companies take the time and money like BMW does for crash tests to make sure those bars don't come into the cockpit in a stabbing motion.

But its a risk you take. At the very least, I know Dinan machines flutes into the bottom of their firewall braces to help them fold in the event of a collision.

Strong strut claims the holes they drill in theirs will do the same.

So yeah... you can modify the braces. I'm sure Dinan has done the R&D, but I'm sure no one has submitted a modded car for a crash test.

Dammmittt · 03-04-2008, 05:34 PM

It shouldn't be difficult to find the buckling stress on the strut bar...just make sure it's higher than normal driving stresses, and less than crash stresses. Crash testing would be more of a formality.

BimmerZealot · 03-04-2008, 07:37 PM

Took a peak behind my grills today, saw the cross brace, looks like its held on by a nut and nothing more. I dont think moving it to a different location would be that hard. Read the Z4-Forum DIY/Review on what he did for the Dinan scoop and looks like they just provided a separate mounting point. Besides a bar of that thickness wont provide too much collision support, if you hit something head on your front is toast.

Dammmittt · 03-04-2008, 07:40 PM

Well...it's gotta be there for a reason right?

i cut mine off per the DINAN instructions for my 3.0.... no problems.

AtoB · 03-06-2008, 06:26 PM

come on guys... i know there are scoops out there.... where are the comments, reviews, feedback?

Dammmittt · 03-06-2008, 07:12 PM

Everyone loves it. What more do you want to know?

jarrow · 03-06-2008, 08:05 PM

The bar that is modified for the Dinan Ram Scoop provides support for the hood latch assembly. It has nothing to do with front end integrity. The original and the Dinan bars are simple hollow aluminum tubes flatten on the ends to provide mounting points.

how it feels at speeds, sounds, fits..... anything of interest. if you are satisfied, then don't bother reading any responses... i happen to be interested in hearing other peoples thoughts and opinions.

Oh SNAP!

I dunno man it's an air scoop...I can only imagine that it feels faster and sounds slightly louder. Its 100 something bucks for 12ish hp...that's a no brainer.

Would removing it / repositioning it cause any detrimental effect to the hood latching assembly? Would rather my hood not fly up while on the freeway if possible

heh

Justincase · 03-07-2008, 08:26 PM

when will these be available to order and have shipped ?

Dammmittt · 03-07-2008, 08:46 PM

They are available now...give RPI a call.

Dinan's scoop went up in price to 349. As did their intake.

C'mon RPI, got one for us non M's yet?

Yes, the list price for the Dinan Air Duct only...if bought within California is $349.00 + Ca tax $27.05 = $376.05.

I was able to locate an authorized Dinan Dealer in the east coast, Thompson BMW in Doylestown, PA.

I bought it for $229.00 (no tax) and the shipping to CA, is normally $10.00However, I wanted 3-Day Delivery and paid an additional $26.00, so my final total was $255.00...My savings was $121.05...

Looks like some may be interested in my earlier post on BimmerPost re the scoop and filter:

The scoop installation took approximately 20-25 minutes, after retrieving a dropped screw from inside the front facia. I recommend placing the screws inside the holes of the scoop before placing the scoop inside the bumper structure. This will eliminate the need to balance the screw on the end of the screwdriver while trying to find the scoop holes in the darker expanses of the front structure. The most challenging part was to decide where to locate the scoop relative to the front brace. The scoop in my car, towards the bottom in-board corner, is touching the diagonal brace. When installed, it appears to be positioned similar to the scoop shown in the pictures on the previously referenced RPI site. I removed the colored RPI stickers and the scoop is nearly invisible with the grill in place. (See attached photos of installed scoop).

The BMC filter was installed without drama. I left the charcoal filter in place. (Somebody convince me to take it out).

After installation, I took a quick spin around my neighborhood. In my garage and at posted speeds, the intake is nicely louder--probably an artifact of the filter more than the scoop. At more agressive extra-posted velocities, the throttle response was quicker, and the intake added a pleasant urgency to the sound of the exhaust. My neighbors have now heard the M Coupe at 7,000 RPM.

Update: I had a nice drive through the remaining snow here in Utah and finally took some photos. I opened up the throttle on the highway and while accelerating to cruising speeds the rushing air sound of the intake scoop steadily increases. However, at speed, I did not notice any increase in intake noise from stock. At near redline, the intake noise is less noticeable over the symphony of the other vehicle systems.
