R2C Intake Installed
 

Just finished installing the R2C intake. Project took about 2 hours working slowly and was pretty easy. Really didn’t have to look at the instructions as there isn’t all that much to do. The fit and finish is perfect and everything just falls into place. I ordered the black nickel and it looks very good. I did not dyno as the closest one is about two hours away and really don’t want to spend the money until I get an UpRev tune-up.

Very little increase in noise (if any) but it gives the Berk HFCs a nicer, deeper tone especially above 6000 where it sounds great. Certainly feels like there is a gain in power (really noticeable at the high end) but will have to drive it a little bit more. One thing I did do was monitor the intake air temperatures. I have the Modshack Fang Intake Modification and was curious how the R2C would compare with the stock in this regard. The MFIM
really did a great job on the stock intake keeping intake temp. between 6-10 degrees above the ambient temp. Although the seal isn’t as tight with the
R2Cs the IAT never was higher than 10 degrees above ambient temp unless you are stopped. At one point I idled for about 3 minutes and the IAT went up to 100 degrees and was back into the low 70s in about 20 seconds after accelerating. The car does not have to be going all that fast to keep IATs low – I would say no more than 25 mph. I would certainly recommend the Modshack modification for any intake you are using.

noticable sound comes with a stock exhaust.
take some drive-bys anyways??

Video would be great.....But thanks for the comments. I am interested in this CAI model.

Cool :) + rep

I had heard good things about this fairly new upstart company. They were going to provide me with a test unit and I was going to have an used oil analysis done to see how the filtration was compared to a cotton oil based filter.

Good to hear about the Modshack ventilation mod. I was looking into this down the road after a base line dyno with stock filtration and again with Injen' CAI.

There is a thread on my350 about filtration, it started out with some good input then just sorta spuddered out and got buried in the abyss. It was a shame.

Glad you like the R2C, I am very surprised they have a product out so quick. Then again it does not surprise me, the engine has been out for over a year in the G37.

Good results and about what I see with my custom airboxes with integrated shields.... Getting cool air to the intakes really helps!

Modshack Ventilation mod in the DIY stickies!

Great review and good info on the intake air temps! +1

Mine came in today - I ordered black powder coat. Can't wait to install them tonight!

Questionon air intake temps: Do you think the stock air intake temps (no modshack mod) get as hot as the temps with R2C when at idel for some time?

Does my question make sense?? I am trying to understand if the R2C would cause a power drop over stock after ideling for some time.

The stock intakes are well insulated against engine heat. The R2Cs are insulated also but not as tight so I would assume that the IATs would be slightly higher with the R2Cs after standing for awhile. Also, all the aftermarket intakes use aluminum or chrome tubing and it conducts heat faster than the rubber used in the stock intakes.

:iagree:

True...The stock intakes pull 100% of their air from in front of the radiator. The R2C's are not sealed to the pass through so some engine compartment air is gonna get in...Same as my set-up. IAT's can go as high as 150 degrees when sitting and heat soaking. Ventilating the airbox (either stock or R2C) will bring those temps down fast as soon as the car starts moving.

I didn't do a lot of IAT monitoring when I had my stock box on, but I have since doing my custom intake. I have it up in real time on my Scangauge. No ventilation, temps will run 15-20 degrees above ambient. Ventilate and those drop to 5-10 degrees. The cooler the IAT's the more the timing advance and consequently the more power you have on tap..

good info. thx guys...

Installed them last night and they look great. Now i have to do some driving :driving:

I have the gen 3 Stillen and have been monitoring the intake temps pretty closely. Really wished I had monitored the stock intake for comparison, but the first thing I noticed was the long thin shinny tubes that were bound to suck up heat. Wrapped them with two layers of insulated heat barrier and then started to monitor the intake temps.

Frankly they seem to be all over the board and I've not found a consistent pattern except when driven on the hwy for extend periods. Not counting stop n go traffic, they seem to be as low as 6 degrees above ambient when driven "briskly" on a back road, however sometimes they run 12-14 degrees hotter.

Think your ambient temps being lower plus I have a black car is another factor.

The sensor that monitors intake temps is located with the passenger side MAF and I just put an addition two layers of heat barrier over that sensor to see if it helps. Been trying to tune the car and noticed there is a direct correlation to water temps and probably also intake temps pulling out timing. I've seen a 3-4 degree difference in timing also 10 hp on the dyno just in temp differences.
