Agree.

Talk about underrating your HP BMW. If the upcoming M2 is anything like this monster, then BMW might state the M2 has 375HP but it might end up being 400 horses at the crank.

I'm very impressed with the power of this car but the weight not so much. That's basically 3600 lbs and that's no light weight. Oh well here's hoping the M2 will be close to 3350lbs. I know I can dream and hope

F80NJM3 · 06-21-2014, 01:52 PM

Wow - impressive numbers.

Simply because chassis roller dynos are not precise measurement devices. Testing methodology and installation variability cause significant variances in measured results

I just love looking at beautiful (and clean) shots of engine bays and under bodies. Truly works of art

InTheNightKitchen · 06-21-2014, 02:13 PM

Very impressive. Damn 300wtq by 2.5k and still by redline.

But why is there a dip in tq at 3.5k?

That's interesting. I wonder if it's programmed into the ECU to help with traction?

I'm just spit balling here.

gary88 · 06-21-2014, 02:19 PM

Damn I am liking this car more and more.

N.S.A · 06-21-2014, 02:20 PM

Curious about this dyno. Didn't they just dyno it to have 465hp and 425lbs of torque. If so whats different with this dyno? therefore it is less impressive because they have got more

2 reasons. A ) loss of traction on the dyno (unlikely IMO). B) small timing correction , possibly as result of 91 octane. Data logging with timing would show if this was the issue

That was with a mild piggyback tune I believe. The BMS car's stock numbers were about the same as the numbers from Josh's car.

That was flywheel horsepower. This was at the rear wheels...

Oh ok. I know Terry's tuned car hit good numbers.

Jadar · 06-21-2014, 02:26 PM

Yep. Very impressive. They Dynojet usually comes in a bit higher then other Dynos but this is very impressive nonetheless.

I'd say on a mustang dyno it puts down 410-415rwhp. And that's still insanely underrated from BMW.

Very happy reading this.

rjd598 · 06-21-2014, 02:26 PM

What did an e90 m3 weigh in on your a scales? Would be good for comparison

kardboard · 06-21-2014, 02:27 PM

Awesome work from BMW once again. Hopefully this puts to rest the E9x owners who insist their car is as fast as the F8x models.

JStang · 06-21-2014, 02:29 PM

Holy shit. There is way too much bickering going on about dyno numbers. Even if this is a slightly high reading dyno numbers are higher than expected. Not just this one, but others that we have seen as well.

Danka!

I wonder how much a difference 93 would yield?

@Eas or @tightie any plans for a race fuel run?

In a forum full of women masquerading as men, what do you expect?

Yes, when tuning starts. We'd like to post results from the same session, conditions, etc. to limit any variables.

Spacers make a huge difference. F80 has the perfect perpotions
