I'm not expert on this, but I always read that weight at the wheels was the most costly in terms of performance. By going to lighter wheels and a GFTs (instead of the inherently heavy RFTs), the OP could probably save about 10 pounds at each corner. That would be like adding 15 HP.

I think the rule of thumb on unsprung weight is 4:1.

How do we make the 328 go slower?

I'm constantly watching the speedo because you don't feel you're going as fast as it indicates.....

[UdubBadger]

this has been discussed about 4000 times on this forum...

but to answer your question, nobody has come out with ECU software or an S/C which are 2 ways you could add a substantial amount of power to the engine short of swapping it out for a different motor.

Thanks!

So, if my math is right, GFTs tend to weigh about 6 pounds less than RFTs, and wheels are available that are maybe 8 - 9 pounds lighter than BMWs. That makes about 15 pounds X 4 wheels X 4 = 240 pounds. That should be worth at least a bump of 10 - 15 in HP.

Of course, that small bump will probably wind up costing about $1500, but that is another issue.

Buy a new car.

+1 Going to agree here. I was a bit bummed that we didn't get an 07 335i and got an 09 328i instead. My main reason was the power. But then after driving the 328i, I realized what did I need all that power for anyway unless I'm trying to impress someone or hauling 4 adults everyday and need the power. The 335i is a great car, but the 328i is sufficiently fun for everyday driving. The most I would do is the intake, exhaust and sport suspension over time. Let's be real, these cars go from 0-60 pretty fast. So, even when taking off from a stop light, the fun only lasts for a few seconds before you have to put the brakes on unless you have the money get lots of tickets and pay high insurance. If you live in Montana or New Mexico, you might be able to open it up for longer periods of time.

Get a 335i if you want the satisfaction of having all of those unused horses under your hood. :-)

Here are your options:

1) Buy another car
2) Differential swap

335i FTW!

[demosthenes]

I don't know if the OP has a 6AT or 6MT. The manual is 6/10ths of a second faster 0-60 (6.3 vs 6.9), which is significant. (E90)

If that doesn't do it, get a 335i. The 335 manual is 9/10ths of a second quicker than the 328 manual (5.4 vs 6.3) and the 335 auto is 1.3 seconds quicker than the 328 auto (5.6 vs 6.9) .

Unused? I use the extra horsepower everyday and have recently added more horsies above stock..
Maybe its just me cause im spoiled/used to my cars power delivery.. but when I drive my girlfriends 328 the car lacks the extra oomph I get from my 335, and it makes the drive feels very........ blah..

Wow. 6/10ths of a second and more "umph" really shouldn't matter to the average driver unless you need that extra "umph" or 6/10th of a second in some professional racing club. I guess my point is, if you're not involved in driving as a sport, the difference is not all that much if we're honest. Like I said earlier, you can only go so fast so long without endangering someone else's life or getting a ticket. (unless you live in the west I guess)

Yes, a 335i will launch you like a ride at an amusement park. But, so does a Nissan 350Z, Lexus G37, Audi S4, Mustang GT, MB 300C, etc. Also, there are cheaper pocket rockets that will shoot you out of the gate with a grin. If power is what a person really wants, then those cars would suit them nicely. I think some people buy cars for the wrong reasons. I think the OP, whether he wants to admit it or not, really wanted a pure sports car instead of a luxury sports sedan. That's why BMW created the M3. Shoot, I even hear there's a 300 Hyundai Genesis coupe out there. 70 more horses for almost half the price.

Where does one purchase this Lexus G37? Sounds like quite a car....

I'm sorry. Infinity. Lexus, Nissan, Infinity, Toyota, it's all the same to me.

0-60 times are usually are pretty good indication of how a car will perform in every day driving. There are other factors, but lets keep it simple.


6/10ths of a second difference between 2 cars would be noticed by most drivers. The difference between a 6MT 335i and 6MT 328i is 9/10ths and the 335 feels much faster.

Any g-force numbers? That's where you "feel" the power difference.

G-force numbers would be a good way to measure the difference, but you don't need them to feel the difference.

[Omni]

I'm guessing that the OP has an automatic. I drive a manual 325i and it's supposedly slower than the 328i and I absolutely love the power it offers.

Albeit between 3 and 5 thousand RPMs.

[pjm]

If you just want to go fast, get in line for the new Camaro. 426 HP for around 30 grand. Bargain!

and 0-60 6.1s for 328 is a clear indicator it is a slow car. put that together with a hard to modify non turbo engine and it is obvious (at least to me) that power adders are not the way to go with that car

That said if you use a stock 328 with sport package at a technical track like infineon and it will feel great and you will have a ton of fun

Slow relative to what? A 335i or a Hyundai Sonata? For it's class (mid-range luxury sport sedan) it does pretty well according to Motor Trend/Car & driver, etc. I mean hell, I've seen minivans screaming down I-95 in VA going 95mph. Pisses me off because minivans should NOT go that fast, but hey, speed is speed right?

I was traveling down I-70 during the 07 V-Day snowstorm in Ohio in my 528i with traction control. What do I see passing me on my left in 5 inches of packed snow on the highway? A Ford Festiva. The tires had to be no more than 3 inches wide. I think I was going abut 40. He was going 55! Was my 528i slow? No.

And for those who value the 0-60 time, spending $10,000 more on a car because it is .6 seconds faster from 0 is not very practical if all they want is a sporty luxury sedan. For enthusiasts, perhaps that extra 6 tenths of a second matters. hell of a lot to pay for .6 seconds LESS of excitement. lol The faster you go, the faster the fun is over. lol

I do love to drive and once the kids are out of college, I may take a peek at a 2034 M3. lol They will probably run on steam by then.

0-60 in 6.1 sec is slow?!!! C'mon!
