128i 0-60 time post mods

[jclaib7]

So the advertised zero to 60 mph times are:

6.1 seconds manual
6.7 seconds Steptronic

Can I assume that I would be sub 6.0 seconds with the following?

- 2013 128i M sport package w/ Steptronic and paddle shifters
- BMW performance exhaust
- BMW performance intake
- AFE air scoops
- Turner Motorsports Performance Software E82 N51 SULEV

I don't have the tune yet but I will this spring and then i'll do some real world testing. But until then, what is the estimated 0-60 time?

One of those things. Possible faster and possible slower, you'd never know with out trying, but intake exhaut should make you faster .
Is the 128 NA or FI ?

128 is NA.
With that said, his car will be faster but not that much.

The thing that is slowing you down is the auto transmission.

There is no "good" way of doing a launch on the auto. The manual 128i's can go stock 0-60 in 5.9 by revving at 2-3k and dumping the clutch.

That being said, one of the things that will greatly help your times is lightweight rims. For example, my OZ weigh 17 lbs compared to OEM 26 lbs. Thats almost 40 lbs in wheel, which is rotational weight. Also, changing out the RFT will help as well since those are heavy.

Finally, the tune by itself won't do much. You probably want to get 270 hp by doing the DISA manifold mod.

I've gotten about 6.1, even 5.9 on my car (automatic). This was of course, using an iPhone app!

The problem for the auto transmission is that you need to hold out second gear. It likes to shift at around exactly the 55-60 range, so if you shift early, you lose a lot of time!!! (i.e. if you shift from second to third before hitting 60, you will get around 6.4, but you really need to redline it and shift as late as possible (or let the computer auto shift for you))

Those are also the advertised times for the 328i. Do you think the 1 series is faster?

Well according to my handy iPhone app my best 0-60 time is 5.6 seconds. Launching at 3500 rpms and using the traction control on good year run flats. Bone stock. I'm saving the money for the disa swap and tune coupled with lighter wheels and summer tires, that should drop to 5 flat or so.

why are you doing hard launches on your brand new car? not good

I did it a couple times, and the bmw service center told me it was out of its break in period and good to go. Won't be doin that any more!

Yeah I did a couple of long trips with hyway and city driving to break it in.

nice! sounds like you're still loving it!

The run flat tires are killing me. I know normal tires will perform better and ride better as well.

The N51 engine already has a DISA. No need for a manifold swap.

- Turner Motorsports Performance Software E82 N51 SULEV Haven't heard of anybody using this yet. Probably 15hp gain.

The only actual gains you'd get are from the tune. The rest is just money spent cosmetically and for beautiful intake and exhaust notes. The only area's where you gain power on the 128 are utilizing the DISA intake manifold(comes on n51's) and catless exhaust manifold with a tune to optimize both. And yes i have dyno evidence of all of this.

[jclaib7]

If I go with the as advertised "up to" performance gains I should end up with "up to" 253 HP and 218 Nm.

Base: 230 hp 200 Nm
PE: 5 hp 3 Nm
PI: 3 hp 3 Nm
Tune: 15 hp 12 N

[Wakka]

intake / PE dont do squat. Plus youre not accounting for diminishing returns.

[TheSt|G]

Intake, exhaust, and scoops make nothing. I would be shocked if that tune makes more than 10hp.

All of those mods are garbage for power and are a complete waste of time if that is your goal. That said, not really sure what your goal is as you spec'd in the General Motors slushbox.

Looking for the sportiest 128i possible within reason and an exhilarating sound! I could not afford the 135i at the time and longevity was a concern.

Of course I spend most of my time in 2nd gear in traffic and my wife doesn't drive stick, thus the flappy panel gear box.

All in all i'm enjoying my first bmw greatly and if I can increase the performance slightly then i'm happy.

Had a 300 + hp 270 Nm Nissan Maxima SV prior to this and driving it was such a bland experience I can't even describe it. The CVT transmission is rubbish as well.

CVT would the worst of the autos. Could always make the wife a better person and teach her stick.

For sound, the PE does that pretty well. For actual performance, you should do the DISA manifold swap. You will actually see real gains with it. Supposedly AA's tune makes the auto less awful as well.

I have the N51 engine. Doesn't that have the 3 stage DISA manifold already?

What is the AA tune? Do you have a link?

Right, compared to the Nissan CVT, the BMW/GM slush box is pretty good. I"m enjoying the paddle shifters as well.

[Andrewcoja]

You're not going to get much HP out of an NA engine without spending too much money. You're not going to get .7 seconds out of some bolt ons. You could get horsepower out of it if you spend thousands on rebuilding and modifying engine parts, but there's no way to squeeze too much out of a naturally aspirated engine.

Yes it does. I believe AA might have a tune for the N51.

You can get 50-70hp out of the N52 in 128i with bolt-ons and a tune(depending on choices).

Hell, with the S54 you can easily get 100hp+ with bolt ons. Same for the S85.
