Its a low quality intercooler that will not be enough for any FBO application.

Got any data to back that claim up?

Any thoughts this one? Anyone running one?

There are a bunch of datalogs from people who got this intercooler and all the other replicas.

Take any of 2-3-4 datalog, compare it to a quality FMIC (IAT, pressure air drop and recovery) and you will get all the data you need.

Ok, I'm a noob with my N54 and I may never update my FMIC but I can't help but fall back on past experiences with heat rejection and radiators with small front face areas. Why would you not simply add small high performance cooling fans in front of the stock intercooler?

Heat rejection is a factor of delta T area and efficiency. The delta t part being difficult if the cooling medium is passing though the cooler at a slow rate of speed and heating up too much.

Don't shoot, just asking.

Oh really? I didn't think they were for sale yet.

Fans are a restriction at speed.

ARM use the same replicas used all over Ebay, its not like they are coming up with their own design.

Either way, feel free to get the 7" ones it is out and post a datalog for a 2-3-4 pull with IAT, pressure air drop and then recovery

ARM 7" vs VRSF 7" (NON HD) - Keeping IAT's down the ARM outperformed the VRSF through a multi gear pull. Down fall to the ARM is the OEM couplers are prone to leaks.

Personally i would go with PSP. it outperforms ARM,VRSF (Non HD), and is as good if not better than the VRSF HD especially for the money

With your mods, i would not go with anything less than VRSF 7" HD

Totally agree!!! learned the hard way

The ARM uses OEM connections which neck down to less than 1.8". It's a major restriction and the OEM connections are prone to leaking and the OEM lower chargepipe that you're forced to use with the OEM connections are prone to failure.

Not gonna get into a pissing match with you. you are well respected in these forums, I've personally tried all 4 of them and i stand by what i said. Also i never said ARM 7" outperformed the VRSF 7" HD

ARM 7" vs VRSF 7" NON HD - ARM did better at keeping IAT's at bay, downfall to ARM is the OEM couplers - ARM 7" 330$ VRSF 7" 450$ - Regular Price

VRSF 7" HD vs PSP 600IC - Performed equally but aesthetically PSP surpasses the VRSF - PSP 600IC 524$, VRSF 7"HD 550$ - Regular Price

Post the data if you had all 4, genuinely curious, especially if the testing was done in a controlled environment.

If I wanted to datalog my FMIC and get the opinions of the guru's of this thread what data should I capture?

Start the Monitor (Auto), DSC off, 2500 rpm, 3th gear, WOT until 6500-6800RPM, Shift into the next gear and after 2-3 sec. release the throttle, slow down and stop the Monitor.

Just need to know what pids to capture using MDH data logging

Hi,
2 gear pull is needed

you want to temp at the start of the pull vs ambient vs temp at the end of the pull

You also want to monitor how fast temp goes back to starting point after the pull is over

Last thing is pressure air drop

Mike,
Thanks for the info. I don't see pressure air drop in MHD's logging options. Is this a JB4 only feature? MHD only shows IAT? So basically capture a log in second gear WOT then normal drive for a minute to see how the AIT drop?

I read about as much of this thread as i could and my phone doesnt make the search functionality on this site very easy.

Can someone confirm if the 5" vrsf fits in the e93 335is without much effort? Thanks.

PSP FTW!!!!!!!!!!!!!!!!!

Silly question, but what is the best performing FMIC that won't require cutting to make fit? Any in the $300-$600 range.

How about Active Autowerke versus Evo I for stock 335is? What's your recommendation?

Wagner is higher density so it will provide better cooling
