R2C Intake Installed
 

I just installed the first major mod on our Z. I purchased the R2C Intake with black nickel finish from forum sponsor Tunerz_Store at a great price. Seriously awesome purchase experience as paid to received was like 4 days and same week.

I took about 30 minutes the other night to unpack and put together the intakes. I took me about an hour this morning to uninstall the stock intakes and replace them with the new R2C intakes including removing the strut tower brace and engine cover. I was able to use both the existing intake hoses by simply rotating/rerouting them and adjusting the existing clamps slightly (I have pics of this, so just ask). At this point I checked the hood and it didn't close at all. It took me another hour to adjust the heat shield enough to get the hood to close, mainly because I misplaced the wrench I was using to adjust the L bracket mount.

Anyway, I finally got to close on its own using gravity from the height I normally drop it closed (about 4 inches), but it seems much tighter than before. I know the heat shield is supposed to contact the hood, but I am wondering how pressure is being put on it - if the hood is being stressed it is not obvious to me. So I am also wondering whether its worth trying to rotate/adjust the intakes back at the throttle body since the heat shield bracket is pretty much a low as it can go right now. Anyone think it's terribly harmful to leave it even if it is a bit snug?

I never heard back from the local auto shop about baseline/no-tune dynos, so that didn't happen. I do not notice any significant difference in the feel, but I would not expect to notice even a 10 whp gain in this car - a 3% gain is pretty minimal. The sound however, is very different at about 4K RPMs and up depending on the throttle and, to a lesser extent, the gear. I am very pleased with the sound, especially for my wife, since it is just about stock sounding the way she drives the car. I have the upshift indicator set at 4K, which she says is perfect for her. She'll hear it occasionally and didn't mind it at all when I had her listen to the difference on the way to drop her off this afternoon.

Ok, so I finally got the videos edited so you can hear the intake compared (poorly) to stock. No YouTube, but these Dropbox links should allow you to watch the video on the linked page or download the file to watch at your convenience (look in the upper right for download button).

I realize the stock video is pretty lame comparison, but I figure most people know what stock sounds like. And if you don't, my comparison won't help you anyhow, since I was bone stock except for the intakes. I was also doing this in a parking lot and found a longer path after doing several stock videos, so I felt comfortable opening it up a little more with the R2C.

Stock Intake 1st Gear to 6K (slowly)

R2C Intake 1st Gear to 7K, 2nd Gear to 6K (bit quicker)

I finally did a dyno for this intake: http://www.the370z.com/intake-exhaus...ml#post1971945

looks good! :tup:

Looking forward to videos and possibly dyno? :tup: Looks great.

I'm :icon08: these myself...

I like what you have done here. :tup: :tup:

grats.. Im looking to do one of these.. this is another option..

Has anyone tried installing these on their 370z. I installed this intake today and was not comfortable with how the hood closed. Way to much pressure was needed for hood to latch. Please share your experience.

Those shields need to seal to the hood to work, so it has to be a tight fit. What are the top edges made out of? Something hard or soft? If soft, I wouldn't worry about it.

You should definitely get a before and after dyno to verify it was worth it.

I'd consider replacing those filters with K&N's that have exposed filter area at top.

Some evidence they outperform the G3's... http://www.myg37.com/forums/intake-a...xflow-cai.html

Ryan, I definitely had some hood issues after this post that were addressed. I PM'd you so hit me back and I can give you some over the phone advice. Or in person of you want. Same with anyone else.

R2C is actually a filter company first and foremost, which was a very serious consideration when I was shopping for intakes. This intake is one of only a few aftermarket products they have developed for consumer vehicles. I'm not sure I would even consider what you suggest without documentation on the potential benefits. Are you simply suggesting to use a cone filter that has more filter surface area? If you have a link to the filters you refer to, or a link with documentation, I'd be interested in looking.

Yep -- that's all. I'll post a link to the kind of filter I'm talking about.

Something like this --> RX-4870 - K&N Universal Air Filters, Universal X-Stream Clamp-On direct from K&N

It would give more surface area, as well as a draw-through facing the factory intake ducts.

May or may not make a difference.

From what I read on the forums it seems people think r2c filters are actually better because k&n lets too many particles in. I wish there were.more serious, long term studies done to really see the differences.

:tiphat: I'm going to use the R2C for now based on their reputation for filters. ZMan8 said basically what I've read.

Yes, this.

I keep searching but still can't find independent dyno for r2c intakes. I really like their design.

The r2c filters use a media 10x far better then the K&N media. The R2C intake is designed to perform double duty, where most intakes fail. It provides a performance gain while still providing the best filtration on market, period.

R2C's main business is contracts for designing filtration systems for military vehicles that are used in climates and atmospheres that the common vehicle will never see.

Any questions or concerns with r2c intakes, please feel free to contact me anytime.

Glad to see you guys are enjoying the intakes, which is the bottom line...

Someone throw me a few bucks, and I'd be happy to reinstall the stock intake back for dyno comparison. :icon17:
