RK Autowerks X5M intakes group buy
Hey guys,
We've been working on these intakes the last month and finally dyno tested them today in their prototype phase. We 3d scanned a stop vehicle to get all the dimension as you see below, design our intakes, test fit them, road tested them, and dyno tested them. If there is enough interest in something like this, we will have these made in carbon fiber like all our other products. Due to forum rules, we will create a thread in the for sale section for a potential group buy. To push these to the final phase, we're looking to start a group buy. MSRP would be $1600 Group buy of 5 people, $1300 to make this product come to life. Final product would be in carbon fiber. To sign up for the product, a $250 deposit is necessary. Here are some images of what to expect in terms of final quality. For more of our work, you can check out our M3/M4 development. http://f80.bimmerpost.com/forums/sho....php?t=1303768 Thanks -R Last edited by Sales@RKautowerks; 09-16-2016 at 09:31 AM.. |

The ///M tax is still alive and well...
Just like exhaust, I'm curious if the changes in diameter from big to tight would be detrimental to airflow vs making it all one overall diameter that matches that of the turbo inlet pipes you're connecting to. Granted mine goes from oval to round like yours since the crossbar above the radiator gives us no choice, but at least mine stays a consistent diameter.

There's negligible drop on intake as it's all negative pressure. I'd be more concerned on getting every psi generated by the turbo to the intake manifold as cold and compressed as possible, rather than spending money on what is essentially overcomplicated CAI that usually best fits NA motors.
The only reason you're seeing flow (and potentially power) increase is because you've reduced the volume of filter. |

You're citing the extensive research you did on the M5 intake, but did you do the EXACT same research with this intake or are you assuming a one size fits all approach while charging near M5 prices without as much design time?

How are these coming along? Buyers, any updates and input? It's been discussed on the GroupMe app that it'd be nice to have a simpler plastic version made, maybe a price point around $600, then more would jump on of these haven't taken off as planned. Although mine are stainless steel and are a one off, I'm glad I got them as to this day they're still awesome to hear :-)

No plastic version will be made, the amount it costs for tooling would outweigh any benefits. Plastic is only worth it if there is very high volume involved. The rapid prototype which a member has been running cost me more than 600, so that will not be an option either. Hopefully i have the first set mid November. Thanks -R |

Really excited for this group buy.
Would love to see more pics of the fitment, especially a front view with the down so we can see what the filters look like. It'd also be cool to get up close videos of the induction noise. Is the sound difference very noticeable from stock? Looking forward to updates!

Yes, the hood, grills, intake, etc are exactly the same.

Prices come down yet to spark interest for a limited product on an already limited platform? What about the redyno you'd mentioned on 12/9/2016?

Without demonstrating undeniable performance gains, irrespective of M-tax, you're asking people to drop US1300-1600 on essentially an aesthetic swap, which will only be seen when the hood is up and you're being Brian O'Conner. Not sure what this cost to develop and manufacture, but you might get some bites at a lower price? I'm sure I can speak for other X5M/X6M owners in expressing our appreciation to you for developing options for our platform, but with all the other performance mods stacked up before this, it would probably get pushed into the nice-to-have pile (IMO).
