Dude, you are crazy...the 335 kicks the shit out of the 330.

From their article... 2007 BMW 335i Dynamometer Revisited: We Test Another One! A few weeks ago, we got a surprise visit from the new BMW 335i coupe, one of the hottest cars of the year. We’d been quivering in anticipation for the 335i not because it’s a 3-series--although that pedigree doesn’t hurt--but because the mind-meltingly fast two-door offers BMW’s first turbocharged gasoline engine ever to be sold in the States. With this in mind, we just had to take the new coupe to the dyno and see exactly how much power its twin-turbo powerplant puts to the ground. The results? 275 hp and 300 lb-ft of torque at the rear wheels--more than we expected. Rated by the Bimmer boys at 300 hp and 300 lb-ft of torque, it was pretty clear to us that the Bavarian masterpiece was a little underrated from the factory. In the weeks since we first published the results of that test, we’ve heard some criticism of our conclusion that the 335i makes "closer to 350 hp" than the reported 300. We arrived at that verdict after some quick calculations, but since a chassis dyno only reports how many horses make it to the wheels, it’s admittedly a hard number to verify. We did four runs with that particular car, and the actual peaks were 276, 280, 280, and 283 horsepower. We published the lowest number to be sure there was no claim that we were exaggerating the engine’s output. (btw - this HP at the wheels, not at the crank) But what if this was a one-time fluke? What if that first 335i was a particularly strong example? Or--gasp--a ringer! The answer to that question appeared in the form of another 335i (this time painted space gray metallic) that BMW dropped off last week. Again, without hesitation, we grabbed the keys and headed for the dyno shop. On the way, we were pleased to find intact the awesome midrange torque and incredible straight-six soundtrack. Reacquainting ourselves with the gauges, we noticed that, as with the original tester, the oil temperature stabilized at 240 degrees Fahrenheit while cruising in sixth gear at 80 mph. Lesser engines would melt at those temperatures! Temperature? Wait! A quick look at the outside temperature display showed that it was only 78 degrees Fahrenheit outside. The last time we put a 335i on the rollers, it was 92. Everybody knows that engines make more power when they get cooler air--and that turbocharged engines are particularly susceptible to heat soak. We stopped worrying and started getting excited. This one might do even better. We strapped the 335i down, started it up, and did three runs back to back to back. The results were very consistent, showing peaks of 285 hp, then 282 hp, and, finally, 287 hp. This 335i was even stronger at the top end than the last one, but not as strong in the midrange. Peak torque was stable through all three runs at about 285 lb-ft. (again, all numbers HP at the wheel, not at the crank) After the final run, we decided to grab audio of the 335i running from first gear through fourth. We expected to have the hairs on the back of our neck stand up at the sound of the 3.0-liter engine at full throat, but what we didn’t expect, of course, was a peak hp number nudging the 300-hp mark. That’s right--shortly after the shift into fourth, this second 335i peaked briefly at 299.93 hp. Looking closely at the chart, there’s a likely explanation for that outrageous number. No, it wasn’t additional torque from a rough shift--the peak occurred too long after the gear change. Like most turbocharged cars, the computer allows a momentary spike of boost before stabilizing it at a prescribed level. We lucked out, as that spike happened right at the engine’s inherent power peak, so we got a little nudge in the final number. Whether the dyno numbers ultimately translate into 300 hp, 350 hp, or 327.543-to-the-fifth-power-hp, the results speak for themselves: this is one very powerful engine. btw - Even if you take that away, Shiv Vishnu's tests show a stock 335i to have roughly around 320HP. And you still couldn't feel a big difference going from a 255HP 330i to a 320HP-350HP 335i...buyer's remorse, man. You can always try to trade your 330i in for a 335i as many current 330i owners are doing as we speak.

What the 330i has to work at a bit to do the 335i does effortlessly. Its the only car I have ever owned where 6th Gear is a passing gear

One thing I have noticed is you really to some extent have to know how to clutch and rev the car to REALLY feel it. I know this sounds a bit silly but after 5500 it starts to die off....(psi drops) I notice that if I rev it up a bit and learn to work the clutch a bit; it turns into a peppy little car

Drive it again...and more and more...my 335 is light years of performance ahead of my old 330 ZHP which I drove for 3.5 years...if you don't notice it something is the matter...with you!

I'm not into the inter-manufacturer penis wagging so much, but in terms of power that's the one thing I always found the 330i lacked (for me). One real test is the passing speeds; which have more real life impact than any 0-60 or 1/4 mile. In the 50-70 and 50-100mph the 335i is almost silly quick; that's where that low rpm torque comes into play.
I wonder if owners of 325i's or non-BMWs figure the reviews of the 330i were over-hyped. Cheers. |

Hard to believe that a car that is about 1-2 seconds faster to 60mph than what you usually didnt surprise you more... maybe its just been too hyped or something? But, 1-2 seconds faster to 60 is like going from a Civic Si to a Nissan 350z...should be a big difference....who knows....

In higher gears at lower speeds it pulls better than my ex E46 M3. |

In some of the in gear acceleration tests the 335 covers the speed increment in half the time. That's what 70lb ft more torque will do for you. But check out the OPs other threads he's just a little envious of the 335 methinks

I'm sorry, but you really need to drive them both, and you will feel a MAJOR difference... they might both have a similar advertised peak HP, but we all know from dyno tests that the 335 has more like 340bhp/tq, not to mention the 335 tourque curve is WAY better... 300ft/lbs @ 1400 rpm! BMW under-rated the 335 by far... it has been called "sleeper of the year" in some car mags even... |

Sorry, but only a deluded person really believes that the 335 is more powerful than is claimed

If the OP's point is that E90s are fantastic cars, whether they have a 4 cyl diesel or a stomping bi-turbo, I completely agree. In 95% of my driving I would not notice the difference between a 325 and 335. I was thinking rather remorsefully the other day that I love my E46 323, and that there is not that much difference between it and my new 335. Is the 335 a ton faster? Absolutely. It's silly fast.
A lot of us BMW fanatics live for that 5%. If we lived in Germany it might be up to 30%. Will M-sport interior bits, LSD, 19" wheels w/PS2s, comp springs, Vishnu xede & milltek diverter make my car all that different? Maybe we're down to .5% now... |
