He got 340rwhp with the regular SSTT....

What was Joel's baseline numbers? I'm interested to know this...also which intakes is he running, the aFe ones or the more common dual cone setups...?

SSTT - 50 hp
AFE dual cone intake - @20+hp
RPI scoops - @5hp

You do realize those are peak values happing under ideal conditions right? Just because the chip is peaking doesn’t mean the intake is, at the given RPM. They all may align but, there is a better chance that they don’t. Also, thinking there's a good chance you don’t get 20 from that intake.

ricer math at its best....

Thats not correct.

The car runs in closed loop, and has 02 feedback all across the board. If it runs lean or rich, it will compensate until it sees fit.

Malek, while I am not expert here the STFT's can only be adjusted so much hence the fuel enrichments on the higher boost tunes. Otherwise, why wouldn't everything be done by just altering the TMAP sensor.

my guess is because they run higher boost?
im confused here sense when i was on a couple dynos with SSTT and some jb2's, there AFR were pretty much the same

I can believe that.
But dry outside ambient air temperature and an evaporative cooler effect on the intercooler are two different things.

13 degree ambient air temps with similiar humidity out won't make 6-8 rwhp difference.
Spraying the intercooler with water (or a misting system) that acts as an evaporative cooler surely can (and will) add 6-8 rwhp.
That's why when some say, "it was 85 degrees out and 85% humidity so conditions weren't the best for dyno testing" I giggle a bit inside.
The 85% humidity in a small way acts like the misting system.
That would be better conditions than 75 degrees out and 20% humidity for sure.

Cool damp "beach" air makes these cars run like a champ. You get the best of both worlds then.

There are many effects though due to humidity. Humidity is nothing more than H20 in the atmosphere in a gas form obviously. The issue is the atmosphere is 21% oxygen. Therefore if you have more moisture in the atmoshere then you displace oxygen used in the combustion process. Trust me though, the increase in humidity is much more impactful in the oxygen displacement then the placebo mist effect you mention.

Temperature is more of a density issue. If you lower the temperature, then the density increases if all else stays equal. More oxygen on cooler days = more horsepower.

Dual cones...

His baseline numbers were similar to every other 335i out there. ~270rwhp, 280rwtrq

[Dan335i]

Whats the average rwhp on a stock 335i with a SSTT and bmc open element single filter?
