Your not kidding. Don't they know that if they all take off early then no one gets home faster. The smart ones are the people that stayed until 5:00 PM. They probably got home at the same time everyone else did....hahahah

2009 C63 AMG
I am friends with the owner of Motorik Concierge in Studio City. His Mercedes Tech is the only one I let touch my car.
I am now contemplating switching from the Renntech short tube headers to long tube headers. The short tubes are not in yet so I am thinking of changing my order. There is a huge difference in power by going with the long tube but I am afraid that my nice mercedes will now sound like a Nascar.

I think you are falsely believing you really achieved some real performance gain through that modification. If there is any real gain it would be so minimal relative to the 451 bhp that you wouldn't notice it.

RENNtech's prices actually are not that far off from other tunes considering what is involved with developing a product.
As for the price on the airbox, the carbino intake cost $1995 and provide zero gain as all it is in a carbon copy of the factory box.
This RENNtech air box has gone through over 5 revisions and has been a product in development for over a year now. Why so long? simply because RENNtech does not make any performance products just for aesthetics. Trust me when I say, I've been waiting for over 7 months for this airbax to be released.
Considering that you actually get a gain of roughly 10-15hp, I personally think that its a bargain at the extra $1000 you would pay over the carbino.

Well said.
And the best part is that people dont understand that a used box is likely an older generation. The 63 and the 600 and 65 boxes are always being upgraded to better designs with better flow. I know a new box is coming for the 600 and 65 to get another 10-15 hp. The box Jon has for sale is the current 63 design and makes real power.
1k extra for 10-15 hp on a NA motor? Thats hardly bad. Just more angry people spouting out false data about RENNtech parts. Its a normal thing for MB world. Thanks for clearing that up!

That's a deceiving way of stating the gains. Its actually $3000 for a 10-15 hp gain, which isn't even good. Just because another part gets 0 hp for $2000 means that the Renntech airbox is 10-15 hp for $1000.

ones too fast according to CHP!
The renntech box looks really sexy!
R&D is a huge cost, and people typically underestimate that for sure!
This is simply not true. As a sponsor you should make DAMN sure you know what you are saying before stating something authoritatively. I will bet you your business vs. mine that the Carbonio is NOT a copy of the same factory box that comes on the CLK63 Black Series. We have done more BS work than anyone, I think I can support that claim.
There are very clear differences that DO make power.
1. The Carbon filters are removed from the Carbonio compared to stock
2. Due to #1, the intake runner from the filter is a complete oval compared to the "D" shape on the stock box
3. The runners were flow tested to maximize pressure and flow into the motor comared to the "D" shaped stock box.
None of this is to diminish what looks like a nice Renntech product, this is just to make sure that customers are getting accurate information.
thanks

Brad,
Your catalog states that your mods to the stock box offer more HP than a Carbonio one. Did you replace the stock runners?
Per the catalog:
15-18 for Carbonio
Up to 20 for the EvoSport modded OEM intake.
So there is potential in the stock one? You would figure that the engineers at AMG would produce a better flowing box using runners are are rounded in comparison to a "D."

This thread is not about any evosport product, so I don't want to hi-jack it. I am happy to answer in email or in another thread.
thanks

The link to my dyno runs isn't right in the above thread, so here's my experience.

Sincity - I bought the VRP C/F air boxes a long time and I need to sell them before getting these. Just wondered if anyone has tried them in an actual racing application and had real world testing.

Dads63-I also suspect that the RTech box will give better readings from the MAF. If you notice on the Carbonio, the way they have the air inlet tube opened up under the MAF may not give accurate readings (speculation on my part). If you look at the OEM intake funnel/tract, the air tube surrounds the MAF unlike the Carbonio, the additional air flow does not completely flow through the MAF but rather underneath it. The R-Tech unit has the MAFs relocated further downstream. I am having a hard time describing the difference but I hope you get the gist of it. Th R-Tech box would nicely complement your MHP heads.
I suspect you could duplicate the results of the Carbonio (again speculative) if you cut off the flat section of our North American air inlet tubes to duplicate the enlarged opening of the Carbonio. Of course, the obvious difference with the Carbonio is the slighltly increased box top volume.
I wished someone in China would replicate the R-Tech in plastic.

Next thursday, we'll be testing the actual numbers of the carbonio/VRP CF airbox to the CF RENNtech Airbox. Expect me to have LOTS of data next week, as we'll also be testing the Kleemann Throttle bodies.
