AC Schnitzer 335i Coupe/Sedan -- Higher Performance Package????

So, I just met a nice guy who was driving a totally decked out AC Schnitzer 335i Sedan...20" chrome wheels/Pirelli P-Zero tires (which he mentioned bottom out all the time), aero package, lowering springs, exhaust, and AC Schnitzer decals. He mentioned that he ordered it straight from AC Schnitzer in Germany, and that it's running ~ 550HP and ~ 600 lb.-ft. TQ...huh??????

He said AC Schnitzer upgraded the turbos (running @ 15psi), LSD, cams and other major engine components to give the car so much HP/TQ. I did a search on here, but only found the AC Schnitzer body kit for the 335i, not the "total high performance package." Does anyone know if this is accurate or is he just blowing some smoke?

Although his car sounds great (from the upgraded $4,300 exhaust), we ran together to ~ 80mph from a light and I was ~ 1 CL ahead, which is why I have my doubts about his claims. He said it was b/c it takes so long for his car to warm up and that it's still not that great off the line. I was like, "but you have an LSD, right?"

He says his car does 0-60mph in 3.3 sec., which I KNOW is absolutely false, and that he dusts M3's, Porsche 911 Turbos, and Lambo Gallardos. Of course I mentioned the $1,300 Vishnu PROcede and he knew absolutely nothing about it. He did recall AA's 335i tuning, although he didn't know the name of the "chip" or piggyback box so I explained the story with the XEDE and PROcede. He also mentioned that all the local BMW dealers refuse to work on his car, citing that he completely voided his warranty. I think he might be kicking himself in the as$ about it now.

Don't get me wrong, his car looked and sounded great, but so many ppl hype up their cars, especially when they make the decision to spend another $20k for a total high performance work-over. What's the "real deal" with this car?

AC doesn't have any performance tuning available for the N54 at this moment. AFAIK, of all the major tuners, RDSport is the only that has tuning available for the N54.

0-60 in 3.3? did he have 30 inch wide tires? or an AWD conversion? 0-60 is so traction dependent... there is no way unless he is running some crazy wideness along with his 550hp

Interesting...so do you think this guy knows he got ripped off by AC Schnitzer or was he just trying to blow some smoke up my a$s? He was a little bit older gentleman and really nice too; he said he used to drive an M3, and was going to get an M6, but when he drove the 335i and knew about the tuning capabilities of the car, he went with the 335i.

Well, he did have 20" wide Pirelli P-Zero's (I didn't look at the tire sizes) that were lowered and still sticking out from the rear fender wells; he said he has some major rubbing issues.

550hp from 3 liter turbo is piece of cake. Even 4 cyl 2 liter long sroke Mitsu Evos get pushed beyond that. However, ACS does not sell a kit like this officially, though the guys could put the power to a car. It is easy to lose traction and thus lose the race from lights, but I doubt he having quite 550 hp. If you see him again ask about the mods in drive train, clutch especially, and injectors. Or directly where can you order the package from

It's a piece of cake to squeeze power out of a turbo charged engine, but to do it safely while maintain the hp output in a driveable manner (I wouldn't want to drive a car with a major turbo lag), can take quite a bit of time.

Last time I heard, Schnitzer does not have a particular strong R&D program for BMW engines, so I'd call that BS

Some turbos are big enough so that under normal driving it feels just like an ordinary NA car - no boost at cruising revs. Quite drivable.

I'm told by one of the SA here that ACS own a BMW dealership southwest of K-town. They just kicked off a hugh promotion on ACS parts installed by the dealer that won't void the warranty if installed by an ACS tech.
I went through everything ACS has to offer and did not see any engine mods for the N54. That's not to say that its not true but...

Yeah, I figured either this guy had no idea what he was talking about or he got the ACS aero kit and exhaust (he mentioned it cost $4,300 for the exhaust) and some shop in Miami upgraded the turbos, cams, lsd, etc...maybe.

So his car is still not that great off the line but yet he does 0-60 in 3.3?? lol. I'll hate to see it when his car gets better off the line!!! Watch out Bugatti!

I am surprised that he even raced you. Guys that talk that much bullshit usually have some kind of excuse.

Maybe he got cheated by the guys that worked on his car. Who knows? There're always dumb people out there throwing away money for no reason....

It was definitely strange, especially since he was a nice, older gentleman in his 50's or early 60's even. Maybe he really did get some upgraded turbos (he mentioned...oh, you have the stock Mitsu turbos; I've got...), cams, and such from a tuning shop in Miami (not from ACS), but it certainly didn't seem like some sort of supercar or anything. It sounded and looked great, but that's all. I don't know...maybe he wasn't really racing.

I'll tell you though, I'd really like to see the look on his face when he looks up "Vishnu PROcede" on the Internet!

If you drive a little south (mid-S. PB cty), you might. He's got a dropped, silver 335i Sedan with ACS stickers all over it and pimped out ACS chrome wheels (with chrome lips). Nice guy though...I just think he didn't really know what he was getting for all that $$.

Another funny part I just remembered about my discussion with the guy. When I told him about the $1,300 PROcede, he said, "you should've got these ACS upgrades direct from Germany like I did, except for the $4,300 exhaust (he said it was too expensive and too loud)." I said no thanks, I didn't need my car to look or sound like that; I just wanted it to go faster!

Then, he mentioned the $1,000+ "chip" from AA in Miami. I told him it wasn't a "chip," but rather the XEDE piggyback computer and how Shiv started all of this 335i tuning with the XEDE and then dropped it for another box which he calls the PROcede (so then AA, RD Sport and others picked up the XEDE for 335i tuning). I even mentioned Shiv's upcoming downloadable PROcede v2.0 s/w which should give it another 40+HP and 50+RWTQ! He had no idea about any of this.

I wonder if he really knows what he's got under the hood...totally stock or upgraded, larger turbos, cams, etc.? If I ever see him again, I'll ask him specifically who/where installed all those upgrades to his car?

Yes, I'm sure it's definitely possible, but the guy I ran into today said it was all AC Schnitzer straight from Germany, and that the shop in Miami just services it since none of the BMW dealers in S. FL will. Then when we went from a light, I pulled ~ 1 CL ahead; I would've expected his 550HP/600+TQ monster to blow me away.

I have followed that thread for awhile, but that havent mentioned any real dyno #s yet. And with the setup they are purporting, they should easily walk away from sflgator's car.
