You guys know that the n20 is underrated from the factory right? Tuning companies have measured figures around 240whp stock, so its not hard to believe that the JB+ could push it over 300hp at the crank. Now I'm not saying that the OBD HP reader is accurate, but it could be making about the same power as a stock 335. A JB stage 1 might make 330hp.

How about the dyno reading from the OBD port?

Well like I said, an "OBD port dyno reading" probably isn't accurate, and most likely inflated his numbers. He should be making just a tad over 300 crank hp with a JB+ according to BMS dyno charts. I'm sure its a noticeable improvement over stock.

That makes two of us, but I thought I'd stir things up a bit first.

No - 240 at the wheels is not accurate. 240 is OEM flywheel hp. A JB stage 1 would not make that kind of power, nor would a JB4. Downpipe, bigger turbo, bigger intercooler, metal chargepipe (plastic OEM won't handle higher boost), and E85 or high-octane fuel would get near that figure.

I have a 2013 335i with the MPPK and MPE, roughly 330 hp at the crank, allowing for the above stated underrating. My wife's bone stock 2016 228i convert isn't anywhere NEAR 240 hp at the wheels - that would imply around 265 at the flywheel minimum, and it simply doesn't have that kind of power.

There is no "OBD port dyno reading"...are you just making this stuff up?

Actually, it's not inaccurate, maybe I rounded up by a few horses but 234whp seems close enough to 240whp to make my case. Unless dyno charts have started reading in crank hp, then this chart from BMS proves that. The stage 1 should make roughly 310 crank on pump gas without any supporting mods. Maybe you should take your wife's 228 to a dyno, you might be surprised because it has the same N20/N26 motor as the car in the chart. Butt dynos aren't usually very accurate. It also might feel slower to you because it's a heavy convertible. Just my two cents.

And to respond your other response, I was making a reference to mbanks21 saying "how about the dyno reading from the OBD port" which is why I put that in quotes. No, such a thing doesn't exist. No, I'm not making it up I'm paraphrasing a previous poster. And no, the OBD port dyno reading in question that the OP claimed 330hp from is not accurate. I know it may have been hard to follow the entire 1 page thread to keep up with the language being used, but I hope I could clear the confusion for you.

OBD port dyno reading

OP actually never said the word dyno.

Okay, I wish you lived closer to NY and would love to race u one day)
I don't want to be in the position where I have do defend my words, but why to call my thread a bullshit? As I said before, I am also surprised of my car, but I don't go around accusing other people's statements..
I know that OBD reader is not 100% accurate, but close enough from my experience as I used it on my 2 previous cars mazda 6 and chevy malibu which I still have.
But anyway, thanks for the input)

No but it was implied by "So today I plugged in my OBD bluetooth reader and it showed my top HP and Torque being around 330 both".

How else can you get HP/Trq readings without a dyno?

[duercos]

and it's a JB+, not even stage 1 I am using

[crono06]

Maybe he meant OBD Bluetooth EMF wave reading?

[duercos]

I meant a $15 OBD bluetooth reader yes

[uncleruckus]

Certain ODB apps/readers can "estimate/calculate" an HP reading. IIRC The Torque App does have an HP reading, however this is quite different than a real dyno reading.

There's nothing you can "read" from OBD via bluetooth or a cable that will give you any kind of horsepower and torque readings. Put it on a chassis dyno and you'll get an accurate reading. There's no way you're getting 330 hp/torque from a 2.0 liter 4 with nothing but a JB+ and a K&N drop-in air filter. That's 90 hp above stock 240 rating, for which you'd need a lot more than a JB+ and an oiled-cotton air filter.

The device is https://www.amazon.com/Veepeak-Bluet...=obd+bluetooth

and the app I am using is android DashCommand.

I will get to a real dyno one day, but for now it is better than nothing..

I'm aware of that. I think mbanks21 said that first, and I think he used the word dyno instead of "horsepower reader" which isn't a big deal.

[RoundelM3]

Whatever...anyone who believes they can actually get a meaningful power and torque reading from the OBDII port with a "reader" or other application clearly knows nothing about engines and how power is determined. I started working on cars and building engines before the OP's parents were in high school, hence my ability to detect BS. In fact, I hooked up my BS-O-Meter app to this thread via my BlueTooth WiFi Direct with USB3 adapter and it went completely off the scale and I had to reboot using something I read a chart I found on the internet and it was true because they can't put anything false on the internet.

I guess you are really old then)) Or just the fact that you paid more for your n56 "M PERFORMANCE" and my n20 happens to be more powerful..
Anyway keep your BS opinion to yourself..

Prove him wrong and test it on a dyno or go to the 1/4 mile track and see what speed you trap at.

After all you are probably faster than an n56 since they don't exist.

[uncleruckus]

I highly doubt a lightly modded n20 can compete with the VQ37 engine in the Infiniti from a raw HP/torque or numbers perspective.

Doesn't mean you can't beat them in a race tho.

i remember my first beer.

you clearly didn't know I mistyped "n55"?)
After seeing so many haters in this thread I would like to do a dyno tbh.. Anybody knows a trustworthy place in NY?
