I wonder if the 3.0 will EVER grow to more than 230 HP
3273
39
All these speculations about BMW upping the power output on the 3.0 liter engine because of competition...Some say 260 HP on the 330 in 2003, I've seen figures ranging from 230 to 250.
BULL.
The 3.0 liter engine, at current iteration (M54), is about as finely tuned as an engine of this size can POSSIBLY get at 6,500 rpm redline (without introduction of new technology). The ONLY way BMW can increase the power output of the 3.0 liter engine is by either force induction (hence the bi-turbo on the 5 series) or by moving the redline up another few thousand RPMs, ala M3 engine. Frankly, I don't think the Aluminium block in the 3.0 can sustain such high RPMs, otherwise BMW wouldn't have use a cast IRON block for the M3 engine.
And judging from the fact that the new Z4s are coming with the identical 3.0 and 2.5 liter engine, we can safely assume the 2003 3 series will NOT see any powergains, and if the numbers are different we can be assured that it's BMW Marketing working their funny accounting. Most likely we WILL see some new engines by the end of 2003 on the 3 series once the 5 series is introduced...Perhaps Valvetronic I-6es with power in the 250hp range from the 3.0, but it will NOT happen in the 2003 model year.
So take it for what it's worth, there will be NO changes for 2003 for the sedan, and very minor changes on the coupe if any.

Although I don't think there will be any power increase for 2003, for the reasons that you state above, it is possible to have a higher hp 3L engine than the current one. The 240hp '95 E36 M3 is proof :flipoff:
Although what you said above is more than likely, I HAVE to ask bro... Are you with BMW AG or something? 
The HACK said:
Yep. If the single VANOS 3.0l euro E36 M3 engine can generate 286hp. Double VANOS in the current 3.0l should come close to that if BMW sees the need. Turbo just sounds so Volvo, Saab and Audi.

Valvetronic. Which will also make the e-throttle debacle right, we hope.
Edit: And I see I need to work on my reading comprehension. :banghead: Perhaps if they improved their tolerances, though. I remember someone's 330 dyno'd at 250+ bone stock...

Where was this???
i bet they shave $1500 off the list price though... bookmark this post.

THE HACK,
Your analysis is most impressive and "dollars to donuts" I predict that you are correct. A limiting factor of the valvetronic system is the time lag required for the valves to be electronically adjusted for each stroke. Consequently, the valvetronic system appears to be incompatible with the higher revving engines such as those used in the "M" series.

What debacle?
All that I hear is unwarranted *****ing here :dunno:

Yeah. Running 103 octane JET FUEL, in 32 degrees farenheit with 0 humidity, and the engine fell apart right after the dyno run...And a giant fan blowing compressed air into the intake.

I HAVE to agree... I can't ****ing tell the difference between my current 325i (or former M3 in non-Sport mode) and my former 00 323Ci... Heck, it must be even better than the mechanical throttle with the Dinan SW...

My sister, who is as close to a disinterested party as you can get started ranting about the delay within 1 block the first time she drove my car. The sticky pedal is also rather irritating.
The problem with the e-throttle, IMHO, is mostly with BMW's software. The lag also increases depending on how the car is driven. It freaking irritating. Over time, throttle response sucks more and more and more, until I reset the computer and I get it back. With an average speed of 15-19MPH, I just don't have the opportunity to drive the piss out of the car constantly.

Wouldn't know. I just recall a post on bimmer.org, along with a lot of comments on how BMW's tolerances allowed for up to +10% over spec.
The HACK said:
I've never driven an older E46. However, the throttle in my old E36 was MUCH more immediate. With software, I'm sure the e-throttle is quite decent. If BMW would simply give us a sport mode outside of the M3, I suspect that a lot of the *****ing would die down.

Nice... Where can I get some of that? :angel:

Oh, I could rephrase that...

And I ****ing well can! :flipoff:

ALEX325i said:
I'm with Alex. Lag? Sticky pedal? huh? :dunno: Maybe this is a sign of inconsistent manufacturing by BMW, and not some design problem.
I can tell a difference, but the only thing that I find significant is that the throttle is lighter than mine (M52TU E46s have heavy throttles). That really is it. :dunno:
It makes it easier to blip the throttle :lmao:

That's exactly what theHACK said after driving my car.
