S55 vs. S65

Being a "GT car" and being a "sports car" are not mutually exclusive. If this wasn't evident based on the fact that there is no universally accepted definition of sports car, you'll realize the argument falls apart on itself because BMW also races the Z4 in GT classes.

in the end the M4 will sound like a 335i. that alone does it for me

I know right!!?? Bet he ends up with one eventually. My 335i doesn't sound like an F80/82.

a LS engine. you can do full exhaust, intake, heads and a cam all done at a much cheaper price. also you can even work on the car your self. with the mods i listed you can gain 100WHP over stock without doing any FI mods. all n/a and will cost under 10 grand. you also could do a stroker kit for the z06

my whole thing was about N/A, i wasn't talking about FI.

Mostly agree, however, cams and a full exhaust are certainly possible for the M3 as well and will provide gains. Not too surprising that a car with the specific output of the Z06 has a bit more low hanging fruit with regards to tuning. Again, I primarily disagreed that the S65 was maxed out from the factory.

its not REALLY maxed out. but its just so costly to keep the car n/a to gain real power. of course with the right price it can be done! i mostly see people going s/c route to get the real gains. because it actually cost the same/more to do big n/a builds. which is completely not the case for corvettes.

all i am saying is that big V8 push rod single cam motors are easy to work with and gain power cheaper.

Just FYI for s&g:

A heads/cam/bolt-ons Z06 will make just under 600whp on most dynos on pump gas.

A cam/bolt-ons LS3 Vette will make just under 500whp on most dynos on pump gas.

As a side note, I wouldn't FI most factory NA cars unless I was made of money, just IMHO.

The e92M is a more usable, capable sports car.
Technically and practically speaking

+8000

If the z4m was my only car it'd be gone by now.

I know s55 won't sound as goog as s65,but I absolutely sure it won't sound same as 335 it will be louder and more aggressive anyway.

S65 is great engine no word, but I absolutely sure that s55 won't be just tuned n55-n54, it would be much better overall, faster, safer and better sounded car anyway.

i am past the point of comparing it to a S65.

i read a early review on the car, and they said the M4 sounded like the 335i.

just wait

http://www.caranddriver.com/reviews/...st-ride-review

"The M3’s exhaust note is deeper and louder than that of a 335i, but not radically different. It sounds most distinctive during gearchanges, when the engine emits a hollow burp on upshifts and staccato brap-brap-brap on downshifts"

Therein lies the problem. No one has been able to flash tune an F series ecu so far. BMW did this on purpose. Also, I wouldn't be the first in line to increase boost on a vehicle already running 18lbs right out the box, with some pretty aggressive timing no doubt!

A sports car, by definition is a 2 seater. M3 coupe, 1M, etc, are all 2+2

So far it's looking like a tuned N55, with two turbos, and a stronger crank/pistons. Far from what an N54 is.

So pretty much exactly like what bmwm3redblack said

not really he thinks the car "wont sound the same" when i just proved to him it will.

if you analyze what i quoted. they said the most differences are when the car is shifting. making that all some fart noise. (sarcasm).

both of them are 3.0L I6, one has more air going through it.

[Boss330]

So what we can establish is the following:

-The F8x will have a I6 sound track
-The E9x has a V8 sound track
-The 335i has a I6 sound track
-The 550i has a V8 sound track
-The E46 M3 has a I6 sound track
-The E39 M5 has a V8 sound track

I hope no one comes here and says that the E30 M3 has a I4 sound track, because that would be a big revelation...

Allmost as if someone told us that a violin sounds like a violin and a guitar like a guitar... But that they can make very different music while still being recognized as a violin and guitar respectively...

To me the sound in this clip is clearly I6 but not similar to a 335i:

So in fact it won't sound the same as a 335i, as proven by your own reference...

A little hint: When your source says it sounds "most different during..." that means it doesn't sound the same. Sound the same means there can't be any "most different" in there anywhere

Where is that definition taken from?

A 911, 928, 944, Ferrari FF, McLaren F1, Aston DB9 (or even DB5) wouldn't be a sports car by your definition...

BTW, a BMW i8 would be a sports car but none of the current M cars would be classified as sports cars. Theyd rather be called sport sedans.

Did you even read what you posted?

"..not radically different" still means different, it can only do so much as it is still an I6

"deeper and louder" "most distinctive"

The most interesting thing is that he keeps on posting stuff like that

But the 5min video from Ascari I posted on the previous page is probably the best sound clip we have so far. Does it sound "the same" as a 335i or doesn't it?

A guess:

Ezio: It sounds exactly the same as a 335i only it's slightly different... Or perhaps: it sounds even worse than a 335i...
