Those are beautiful cars, but pretty boring to drive. Unless you are looking for a big cruiser. :) They are like driving a luxury boat. :D
I drove an M6 at the BMW Performance center in Spartenburg for 2 days (as well as the M5). For a 2-ton car it is really pretty impressive and definitely not boring. Best seats I've ever driven in. But I have not driven the non-M version, so I can't speak for the 650i.

Forgot to post a pic of my engine. One time I was trying to stop real quick and my brake shoes flew off hitting my headlight fluid pump and damaging my muffler bearings.

Also not true.

Torque gets the car rolling, and accelerating. Horsepower at high RPM allows the engine to sustain acceleration by facilitating more torque to be produced.

A bit of mechanical leverage through the drivetrain to a set of rear wheels with a short rear gear certainly helps things too. ;)

or you could just say HP = (Torque X RPM) / 5252 ...atleast at the crank

Did the crankshaft turbo timing chain skip? You might want to check. That's pretty common when you get brake overspin. :p

You know, I didn't even think to check. I thought it sounded a little different afterwards. Ah well, since I have to tear it apart I might as well replace the turbo sprocket and upgrade to a turbo piston. This way gravity will keep the chain on.

That is quite possibly the dumbest, most ill informed comment I have ever read on the internet. Pistons go up and down but the crankshaft to which they are connected rotates believe it or not, and the mass of the pistons and connecting rods causes rotational inertia as a result. The heavy flywheel attached to the end of the crankshaft goes round too, that's what it is for. The propshaft, driveshafts and gearbox components are also heavy and rotating at speed. Engine braking is caused by compression, and both types of engine require and use compression, so not a great deal of difference in engine braking, and both will stop without fuel in a similar time. There is no significant difference whatsoever in stopping distance caused by the engine type. As for ripping the brake callipers off... Jesus. Provide one bit of proof for any of it, and I might stop laughing long enough to read it :rolleyes:
Not to mention the boxer engines are horizontal and exhibit the same engine braking as inline and v motors. Hahaha, I wonder what he would say about these engines:

and we'll throw in my lovely VR6 for good measure

OC Baby!
My new baby, I just picked it up yesterday.

2010 BMW 335i M-Sport Sedan with Black Sapphire metallic on Chestnut Brown leather and yes it's a manual!

I'm the blond one fyi. ;)

Wow you're one lucky guy - that is a great car. I would have killed to have that at 17. Congrats.

Gorgeous car. But please get a haircut.

Shell V-Power FTW. I only put that in my car, unless I wanna play with the 93 Octane program, then it's Sunoco94. Day and night with that program, according to my butt-dyno.

Your father just bought you a fifty thousand dollar car, which you will probably stall out on, burn the clutch out, and total in two weeks. Money well spent...

Give him a break. He already said he's been through driving instruction and performance driving school. He might have already learned better skills than you've ever had at this point. I teach driving skills (through BMW CCA and TireRack's Street Survival School) to teens and often they've been taught bad skills and bad habits by older drivers (like parents). Hell, he's probably learned to heel-toe downshift if he's been to a performance school. Can you do that? Do you even know what that is or why it's used?

I do know what heel-toe downshifting is match revs and be in the right gear, so that you don't get the "jolt" most of the time used in turns, or for a really good stop. Yeah I know what it for. I can do it, as I have been driving manual vehicles for a long time now.. But really it just bothers me when parents go out and buy their kids $50,000 cars, when most of the time the kids will go out and total it.

Like I said give him a break and the benefit of doubt. Who cares if he gets a 50K car. That's between him and whoever bought it. Sounds like it might be a reward for excelling in school. But it really has no bearing. It sounds to me like he's gotten a good start to his driving experience. If he did well in performance school and listened to his instructors he's probably got a better attitude about driving and better skills than 95% of the members here.

FYI: heel-toe is used when *entering* turns, not *in* turns. In a performance situation you don't want to do anything to change the balance of the car while in a turn.

I thought that would be understood but, I understand why you corrected it.

Really more of the reason as to why I said it, is I just find it ridiculous that parents buy their kids such nice cars, and most of the time the kids go and total it, not because they can't drive but because they are trying to push the performance of their cars, and use their "performance driving training" in places that it just makes no sense. For example a kid at my school, totaled his brand new Audi S5. I live in a VERY affluent area, and I just find it ridiculous.

My rant is over. I am sorry that I didn't read the entire story, but I still find it ridiculous. My $.02.

In the RX-7 community, it is pretty common for a little to almost no experienced young driver to get himself a 3rd gen RX-7 for under 20k. Now let's think about the specs for a moment. Under 20k, sometimes far too close to 10k, 0-60 under 5s. Top ungoverned speed: over 160mph. Turning personality: extreme over steer. Driver assist: no traction control. Weight: 2800lbs. An extremely light and fast car that is VERY easy to loose control in.

Far too many times have we seen these young guys crash and burn their RX-7s. But minicrazy592 has a lot going for him. He has actually gone to a proper driving school as opposed to his high school driver's ed deciding his fate, and he has a new BMW with enough electronics to give him a foot massage in case he goes into a turn too fast.

I knew a family of Germans one time. They also had a 17yr old. He had attended racing school, his uncle owned a Porsche speed shop in Germany, and he was constantly around speed. At 17yrs old, he was one of the best damn drivers I had ever seen in my life. He was cautious, careful and paid attention to everyone on the road.

The only thing minicrazy592 may need to worry about is peer pressure. If he was brought up around a good family that taught him well, and if he is one of the few 17yr olds with an open mind and great respect to the machine that he has been given, I have full faith in him. Not every 17yr old is the same (although 95% of them are the same), and I have seen proof of that myself.

Don't forget the ones that buy super clean FC's then a month later sell it for half the price because they cant handle the fact that they were only able to drive it once that month :D
