F80 M3 vs E92 M3 Dyno Numbers by Motortrend

Haha, love that "expensive jeans" story. I want to know who that is. PM me. In any case, I was a bit surprised when I started seeing E9X guys just blatantly hating on the F8X considering I AM an E9X guy lol.

It wasn't me, but I admit I did check my SO seats for blue stains after the first couple times I drove it. FWIW, some people go by the theory that you shouldn't wash jeans, which makes them prone to leaving blue dye where you don't want it.

Hi guys,


to give you guys some other dyno results I want you to check out a couple of cars we tuned over the years. (I co-own one of the bigger BENEFRLUX tuning companies)
I tough this was common knowledge.

I have never seen an M3 who had the power they promised xD

the power in the graphs is the Wheel PS!! not the Engine power!!


all of those M3's (E9x) are measured here at our dyno facility. We have a RAM-AIR effect system that can measure up to 1500PS.
FYI, We did the test for 9FF Vmax car 1400 HP

aren't people still having problems cracking the F10 M5's ECU? Which would probe my mean that cracking the M3/M4's ECU will be a ways off or will be far more difficult.

Naa son, gotta tell your neighbor how much hp you car has more than his

All of you do realize that as a motor gets older it loses power (due to buildup in the motor, older less efficient parts etc.). The important question here is how old is the E9X that was dynoed?

[signes]

FWIW my car (08 E90) dyno'd repeatedly at 305-310whp. Running 91 octane in cool temps, lots of fans, etc. Same results even on diff tires. I know of a couple others that wound up with similar results.

Pulls were done on a Dynojet which is AWD capable but only rear rollers were engaged.

It's e85 mix between 30-50% with 91 that estimates to be around e30. Most of this term/practice came from the n54/55 that could not take more than 50% e85 due to stock LPFP issues.

Oh, the douche BMW owners existed LONG before the 335 even existed.

[BOOstJunkee]

lol @ all the e9x guys complaining at low numbers. Regardless of the numbers, its just showing how much stronger the F80 is. And thats a 70 WHP gap!

ethanol fuel

It refers to the Ethanol content in fuel.

E10 is what you generally get at the pump. 10% (usually corn) ethanol.

E85 is made for "flex fuel" vehicles usually, and contains 85% ethanol and 15% gasoline.

What's the big deal? Well, lots for starters, but to simplify it: turbo/supercharged cars generally benefit greatly from "E85" because it takes more energy to burn.

Most of the cars...BMW included are meant to run on "pump gas," which usually contains 10-15% ethanol (E10), which you would recognize as "Premium."

There is muuuuuuuuch more to the story, but I hope this helps a little.
..................
Regarding the dyno dick measuring contest when it comes to power output.... Wow. It's almost to the point that people should post graphs without numbers, so all you guys can compare whats really important: power curve! Peak horsepower is almost meaningless without a proper curve. I can't believe anyone here is surprised that the F8x engine has better power curve than the E9x engine. The flexibility that turbos give you in that aspect is incredible.

Piggy back tunes. The same tuner has M5s hitting well over 600whp with basically the same setup as the M3

The TQ curve is still garbage, drops off so quickly...while the e9x TQ was low at least it was flat.

[Leonardo629]

You clearly don't know how to read dyno charts

Doesn't feel like it... the car pulls WAY harder than the E9X all the way to redline without any perceived "drop off".

You are correct, I forgot turbo cars generally dont have high end TQ. I am use to looking at American muscle cars where the TQ curves just go up and not down...my mistake

[OverDriven]

I'm sorry, but how the f#$% can a bunch of dynos read so differently? Isn't there such thing as a friggin dyno calibration?? Or is it that none of these guys ever get their dynos calibrated? 1 HP is equivalent to 746 Joules per second. That's cold, hard, objective physics. This is like each ruler manufacturer using a different definition of an inch. We standardize things so we can have a basis of comparison.

Sorry for the rant, but I just find this shit hilarious. If you run a dyno, get your shit calibrated or you're just lying to your customers.

Show me a dyno where the torque just continues to climb to the end. It doesn't exist. HP always crosses over torque at 5252.

I am not an expert in combustion, but that statement does not make sense to me. I always understood combustion to be an exothermic reaction.

My understanding is that ethanol needs more energy to vaporize, so it has a cooling effect on the intake charge and thus yields better resistance to detonation during the combustion process.

Which American muscle cars are you talking about where the TQ curve doesn't trail off at high rpms?

[MSteve5036]

The F80 dyno looks a bit weird to me based on all the stuff we were getting before the launch.

Power difference is definitely there and you can absolutely feel it. The new car absolutely rips.
