R2C intake dyno'd ... ever?
 

Yes I have searched on both here and on google, but never found anything... just curious if anyone here has these and if they have had the car on the dyno? It looks like quite a nice set-up... especially if you put some fang vents to it.

That's because they're for the G37 but can fit the 370Z. Browse through G37 forums and there's plenty of dyno's on it.

Not to be a jerk but a G37 is not a 370z... the G37 with that intake yields similar results as the Stillen G3's which no SRI set-up has done on the 370z's yet. Please just simply don't answer if you don't know what the answer is.

Not sure what answer you're looking for since no one has these in the 370Z and dyno'ed it. Or maybe I should've said that in the first place? The G37 share the same engine so not sure why you'd say a G37 isn't the same as a 370Z but main difference would probably be the aerodynamics of the front bumpers and how either one takes in air. Sorry I couldn't answer your question because I've tried looking into this before when I was looking for a Stillen long tube alternative.

I was on R2C's website and it looked like they had an intake model specifically for the 370z.

I'm also interested in any dynos on this intake and if it's worth it over just dropins and post maf tubes.

Personally, I'm skeptical that any sri will be worth the $$ but I hope I'm wrong.

I don't think the gains would be worth it... SUPPOSEDLY the G37's get the same power as the Stillen... but we're talking about a completely different car as far as air flow and such.

oh no big deal man... I wasn't trying to come off like a jerk... it is the same, but yeah the aero of the Z seems to make a difference when it comes to the different intakes. I wish they would make the same power, since it seems it would save a bit more install work and it really is a nice looking intake set up.

It looks like it's made of chrome as well. Can't remember where on the forum I read it, but I believe it was proven that chrome absorbed and retained more heat from the engine than other materials. That, to me, would be a detriment to performance. Looks nice though.

I still think that for the money, you really can't go wrong with the HPS, Mishi, or Z1 tubes and good filter.

Now, having said that, someone go buy the R2 and do a dyno to prove me wrong! ;)

If im looking at the correct website (R2Cperformance.com) the 370z and g37 share the same part #. It looks just like the K&N Typhoon to me. BTW a guy on myg37 is about to post up before and after dyno results.

the cars are NOT the same the way the air flows... I don't know whats so hard to understand about that?

Not trying to be an a$$ but what does airflow have to do with a car sitting still on dyno. There is no airflow.

Ok just got the results. Dude did three pulls before and after with about 3hrs in between. He stated that he did do some interestate driving between so the ecu could compensate. Only previous mod was berks hfc's. Average between all pulls before (263hp, 234tq) and after (276hp, 241tq). So basically he gained 13hp and 7tq.

have you been to many dynos? They usually have air moving to SIMULATE going down the road bro.

That's pretty damn good for an SRI honestly. The big ? is 1. will a 370z alos see similar gains and 2. are these gains any better than drop ins and post maf tubes?

Still intrigued by these R2Cs...

I have the R2Cs but have never dynoed them by themselves. I have the Modshack vent mod and often monitor the air intake temp and it is usually about 8 degrees above ambient temp so the vent is doing its job. It is very hard to duplicate airflow on a dyno even with large capacity fans. When the G3 was originally tested by a well-respected tuner there was a significant difference in the power produced with the bumper cover off and when it was on. I am skeptical of dyno results on intakes because you cannot reproduce highway driving and the ecu is very tempermental with rising intake temps.

So are you saying that the R2C's in the real life have no gains? loss of power?

I don't disagree, but unfortunately there are only 2 real ways to figure out gains, dyno before and after pulls, and 1/4 mile trap speed and times before and after, both those methods have pros and cons.

I think that the R2Cs did produce gains but never tested how much. I think that it is important to get as much cool air to the filter as possible and highly recommend the Modshack vent mod for any intake you are using. When I stop for a red light, the intake temp rises pretty quick but as soon as I accelerate it is back to normal within a few seconds. By the way, the filters themselves have a great reputation and obviously are very easy to clean and no need for oil. I just read the dyno report on the G37 and he seemed to gain significant power

Do you see these intakes giving more of a gain than the K&N drop in filters that someone showed around 4-5 hp?

The top secret intake had similar gains compared to the G3's and its a SRI, but the price is not justifiable.

I also think the intake system in the g37 is quite similar to the 370z in terms of airflow so I don't think g37 dyno charts should be completly ignored. If you look at the inlet holes for the stock filter by removing the front bumper of a g37, they are shaped just like the Z's. I would even go as far and say that the parts such as the filter box are interchangeable, although I may be wrong.

I love my R2C! Butt dyno approves. My car will go on the dyno once I receive my ART pipes.

I know the engine and such is the same... what I am saying is that each car flows air over it differently... the SRI's do not seem to yield results as well as on the G37's PERHAPS because the air flow on the Z is different in that it does not get the R2C's the same way... that is why I am asking for a dyno of a 370z... I don't want a G37 dyno ... I am looking for a stock Z with a baseline and then these intakes. Otherwise, the Stillen is still king for the Z.

Ok, I emailed R2C about their intake. I don't want to post what I got in return from them until I have their permission to share it... I feel they deserve a chance to state their case and then I will ask them if they approve. I will say that they responded quick and that he didn't try to blow smoke. I will quote this part of his email.

"We were able to bring total restriction down by almost half when
replacing the factory intakes and the corresponding gains in power were
reasonable"

I was impressed that he didn't try to sell me on them fake massive power like some companies would do.

Cool, I respect that as well. I'm really starting to lean toward these as opposed to just adding post maf tubes to my setup. Before I take the plunge, I'm really hoping to see some before/after dynos though. If/when I add them, I'll bring them down to HP logic in WPB, do a before dyno there, then have them add them and then an after dyno with an updated UpRev tune to maximize power/air fuel ratio etc. I'm already tuned including the drop ins so it'll be a before/after comparo.

I did ask if they could email me a copy of the dyno charts vs a baseline run.

Whatever intake I get, i'm going to run the fang plumbing.

If you get those dyno runs from him, pls let us know what the results were. No fang plumbing option for my Z unfortunately, since it's a Nismo or I'd be right there with you.

I'm hoping these R2Cs can give most of the top end benefit of the G3's with all of the low and mid range gains of the drop ins/PMTs.

Hopefully he gets back to me tomorrow... he got back to me pretty quick today, but I just checked my email... i'll try to check it tomorrow earlier.

Maybe the dyno will show differently but I really dont see a difference between the r2c and the k&n typhoon. As far as the G and Z go on the front fascia's (air delivery???) give me a break. You might see a 2hp difference but who is to say they are on the same dyno right behind each other.

Then why do some claim they get just as much power in the G37 as those with Stillen, while the SRI's in the Z don't seem to gain much, if any power and sometimes lose power???

Just put my R2C's on my 370z last Friday, seems there is better flow and better throttle response, my butt def feels it......:tup: sounds awesome at WOT

Especially 4th gear!

Ok, I heard back from R2C today. I was sent a dyno chart for a 2008 G37... apparently there is no chart for the 370, so I guess this is sort of take it for what it's worth. The dyno chart is back to back as I was told and is vs. the Stillen intake. Here it is.

Without doing any research I don't know how the g37's respond to other SRI's... can anyone chime in?
