Not even BMW themselves realize the beast hidden in the Z4 3.0.
All you have to do to unleash it’s 1 000KW is to fit a noiseboys exhaust, but remember to give them clear instructions on how to build an X pipe with a 50mm throat.
I tell you, once you have done this mod, you will be eating F12s, MP4s and Aventadors.
Be sure to have “H” rated tyres to take advantage of the full effect when doing 380km/h

The difference in engine output is 25kW (M54=170kW, N52=195kW in the Z4 3.0si) which is noticeable especially when you have pressed the sport button.
Drive both before deciding (like I did).
But it will still not outrun a Z3 with X-pipe, I'm afraid.:flyfun:

Hi
After driving a 2004 3.0i Z4 for a week now!
The Z4 is a beaut.
The 3 litre moves when required, gets pass the speed limit very quickly(with two heavy weights on board – I make no bones about it I weigh over160kgs, and my passage is over 120kg’s)
You can pull away in 3rd , handy when their tons of speed humps, , and a nicely balanced chassis, handles a twisty hill climb no problem
I miss my 5series’s V8’s power, but this little car is more fun to drive.

Well I cant access that section of the forum to defend myself but whats so hard to believe about the claims?
Its a real pity you can that immature bro. Have you ever heard of power to weight ratio? Also, you do realise that I'm at the coast right?
Well that's just nifty dude:bravo:

I have one taking out an Alfa GTV with cams and xzors on a 1,5km run, let me find it and no, unfortunately I dont drive around looking for fast cars with a camera. You guys are making a mountain of a molehill. Pity I cant access my own post!
Whats so hard to believe that I could improve the sprinting capabilities of an already quick car? Many road testers have taken bone stock Z3's to the traps in 14 flats and high 13s. The quickest time for a stock Z3 3.0i is 13.6!
An Audi R8 4.2 manages a 13 flat on any regular day. A Porsche Carrera the same. A 4 pipe M3 runs mid 13s. So whats the big deal about the post? I know what the car could do and thought I'd share some of my experience for the benefit of the Forum. Anyways, its all good. Will find some vids I have of the car and post once I get access to that section of the forum.

I don't really have a dog in this fight, but I would like to point something out to you. According to power to weight figures a 3.0 Z3 is not going to stick with a 2006 4.2 R8 for any amount of gears past second.
Consider that the 2006 4.2 R8 produces 414bhp with a curb weight of 1560kg. This gives it a power to weight ratio of 266bhp/tonne; source. The 3.0 Z3 on the other hand has a power to weight ratio of 171bhp/tonne, taken from your own link. Let's be generous and say you managed to improve your car's output by 50bhp, your new ratio is 206bhp/tonne.
Also, from my link, a 4.2 R8 traps 118mph in the 1/4 mile with a time of 12.5 seconds. That is a monumental difference.

Can't believe people have to stoop to trial and evidence lengths for sharing info.
These videos were taken with a crappy phone, a Honda trying desperately to keep up, so excuse the quality and crappy zoom.
The GTV in question is a 2002 model with cams, decat and software and is one of the stronger ones in Cape Town, known for running M3s and C55s ontop. I opened up 4 to 5 cars until 240 when he passed me on the top, Z3 has a crappy topend.

I did this race 3 times. 2 rollons from 30kph the R8 has me stone cold. From a standstill, I had him all the way to 210kph. And the whole of Cape Town will bear witness to this feat as it took place at a prominent spot. Could it have been a fluke or a bad driver. Sure
