That's something I'd like to know as well, but I did not have the money to do a stock dyno run and then another one after each bolt on.

Since every Dyno is going to give different results (not to mention different cars, ambient temperature, etc), no one is going to have any sort of baseline that is going to be useful for you to compare against.

I'm going to be getting my FI CBE, HFC's and AAM Cobb tune done at the end of the month. I'll be getting a before run, after boltons, and after tune run. Only thing I'll have on for the baseline is the K&N Dropins, the rest will be stock.

What's your impression of the R2C by the way? I'm thinking going that route as well, honestly because I think the colors of the R2C would match my car nicely... How was the install? Sound? Overall?

Otherwise I'm thinking of going the K&N drop in route with COBB Post MAF hoses.

I like the R2Cs a lot. The car was definitely louder, especially above 5k rpm. I actually ordered the black powder coated ones, but received the black chrome, which look really nice. Filters are nice and large and can be cleaned with an air hose when needed. As discussed before, no idea if there were any gains over the stock intake. Installation took me 2 hours or so. I made a little video last year as well:

YouTube - R2C Intake installed on 370Z

I have the R2Cs also and really like them. The black chrome looks great, the filters are easy to clean and the R2C filter has a great reputation. Add this with the Modshack vent and the intake temps stay between 8 to 10 degrees above ambient temps.

I'd love to add the Modshack vents myself aswell

285 on a dyno dynamics aint too shabby. Nice job.

Not true, some intakes actually cause a loss of power. For all you know you actually lost power. You'll never really know unless you do a proper test. I guess as long as your happy with it though it doesn't matter.

How were the intake temps tested?

Maybe down the line I will put the stock intakes back in and do another dyno run.

If you don't do before/after runs on the same day it is going to be pointless. The potential difference in stock and any of the aftermarket intakes after already having other bolt-on's installed is going to be fairly small.

Intake air temps are measured at the MAF and reported through the OBD II. I use a Dash Dyno and it is really very versatile.

I really want to like these intakes. I just wish someone would do a proper test. I don't have money to burn if they aren't worth the money haha

no aftermarket intake is really worth the money as far as gains are concerned, its more about the bling bling.

Does it matter what gear the dyno run was done?

Never mind - I found the answer: 5th gear with the A/T will cause the engine to cut off at about 7k and 160 MPH.
