Been called out by an M340i xdrive

[RM7]

From what I understand, and please correct me if I'm wrong, you don't want to put too much strain on the engine in low RPMs. I was always taught with turbo engines, Heavy load (on the engine) you want High RPMs. I guess it's called LSPI ( Low speed preignition). It's basically lugging the engine. I don't have a ton of auto knowledge, so If I'm wrong please correct me. This may only occur with manual transmissions as automatic transmissions will down shift automatically but I'm not sure. If I'm wrong just tell me to pound sand lol

Except this engine produces full torque below 2000 rpm, so it's fine.

"Twin Turbocharged 3.3L V6:Makes up to 365 hp at 6,000 RPM and 376 lb-ft of torque at 1,300 – 4,500 RPM."

If it was not able to climb out of it, because you didn't have the torque, then you'd be lugging the engine.

In general, 2000 rpm in most engines is not going to be lugging, except for smaller displacement/weaker engines in larger vehicles. There are other reasons not to drive around at 2000rpm all the time everywhere, like piston rings, but plenty of engines are plenty happy just chugging around at 1200rpm. My LT1 has mountains of torque to play with from 1000rpm.

Well, time for some mods. But yeah, my first dinner at gapplebees for 2, my fiancé was in the car. To add insult to injury, she said “he’s winning”while it was happening. Lol

Ah, this segues to the topic I was discussing a few days ago: Engine "chugs" in eighth gear, manual gate.

LOL! your like, "I freaking can see that!"

Update:

He works from home today lol

I've talked to his colleague and he confirmed me he tried 3 more passes back to back and did worse than his PB of 12.05s on all 3. Apparently he was very pissed and tried very hard on their way home to convince him that it was the track, bad launch, the car's fault, no not really, wasn't 100% there, gave me a slight chance, turbo lag, etc.

Spin the "have a reason" wheels really....

So has flappy come to work this week? If so is he hiding under his desk, or perhaps in a closet. Any conversation with the turd at all. Curious as I’ll be go to hell!

"Super knock" is the main concern. Watch this:

That's not really a fair comparison because you have more cubic inches and cubic inches make torque (actually has more to do with crankshaft leverage and rod angles and all kinds of other boring stuff that I won't put you to sleep with ). Can I ask why the piston rings don't like to be lugged? I don't understand and like to learn new stuff.

If you Really wanted to tick her off (and live on the couch for a while), you could've told her that the reason that you were losing was because of the extra weight in the passenger seat that was off setting the power to weight ratio of the Stinger!

Surefire way to the dog house!

No, it's not about lugging pistons, you just don't drive a car at the same RPM all the time, that's what's bad for piston rings. It needs to rev high some of the time to maintain relatively even wear.

It is a fair comparison, because both engines make good torque down low, they just do it in different ways. Modern turbos tap right off the exhaust stacks, often with twin scroll turbos, the exhaust stays very hot and spins the turbine very efficiently, with little lag and at relatively low RPM. Combining decent displacement (3.3) with small turbos that spin fast also helps here. It all adds up to something that makes a ton of torque at very low RPM, the engine does not "lug", unless you are pulling a huge load like you are at 1500rpm trying to accelerate up a grade in the top end gear. But almost any engine is going to lug doing that.

Some are making this out to be like my old 2.0 WRX where if I was at 2K rpm, I was in dog-city and if I was running the AC, I'd sometimes get stuck around slower turns in 2nd gear where the engine would bog so bad I couldn't pull out of it without shifting to first. There were a bunch of little things that eventually helped, freeing up the exhaust, tuning, etc., but the problem was related to the fact that it had to route the exhaust way around the engine to where the turbo was mounted, a very long path with lots of turbo lag. Single scroll, small displacement, long path for the exhaust to go where it would also be losing energy, etc. There you could get into some serious lugging issues, having to spin up past 2500 to jus START making boost and around 2800-3000 for full boost. The difference between that and a modern turbo like in the Stinger is night and day. This is one of the reason the modern turbo cars are much more drivable and quick off the line, they are providing all this torque down low, where it's very usable day-to-day, vs. having to rev up to 4K all the time.

And if you are really getting pre-ignition, you are going to probably notice engine roughness and misfiring.

Thank You for the explanation! What you said makes perfect sense.

Very small update here:

Nick has actually been rather nice to me since last week. He apologized for being a dick and admitted defeat. He's eager to race me again next spring. He's not willing to modify his car all that much since it's a lease so he's going to try his best with what he has.

At this point I kind of like where it ends. I don't intend to annoy him with the lose or anything like that. I guess he learned his lesson. I even gave him a short ride where I let him feel the acceleration using brake snip and he was very impressed. "Definitely launches faster than my car, ahah!" We then tried the factory LC and he said "My car definitely feels faster than that though!"

Not sure it's going to end in a friendship since I still have issues with his personality but I'd rather salute him in the hallways at work rather than maintaining a toxic attitude, you know?

Anyway, it's time to turn the page and end this story.

I agree. I would leave it as it is. Good humbling experience for him. Well done sir!

Sounds like a slice of humble pie hit the spot. We have closure! Thx.

Double win, you don't need to be best buds... and he knows he lost, and admits defeat

 

[AtomicGTL]

Looking forward when you go head to head on the track when youre even faster.

Good stuff OP.

Progress is progress, and it wouldn't hurt to be a good influence in his life. Maybe getting his ego bitchslapped by a car he judged by the nameplate nudged him in the right direction?

Besides, Honda Civics that can gap his Bimmer are a dime a dozen these days, so what the heck did he expect?

A decade ago after my optima experience I swore i'd never buy another from this brand (or its hyundai). Here we are.... Am I in love with the car? No. I don't 'love' cars that way.

After 3 months of ownership I'd say I'm about 90% satisfied. That 10% difference gets spread between the somewhat buggy infortainment and coolant smell. The buggy electronics seem common on many cars these days. The coolant smell is a first for me. All other cars owned also vented to atmosphere - if the res overflowed it would leak out rather than the res exploding - but didn't exhibit a coolant odor nor drop levels after x amount of time.

Are either of these the end of the world, no. My biggest concern was about the car driving and tracking straight. That seems to be mostly resolved. Is the handling as good as my g37s (rwd, hydraulic steering, wishbone front suspension, multilink rear) was? I'd say it's about 80% there. In terms of power, about the same but at a lower rpm.

Would I claim my car is faster than so and so? No... don't care about such things any more. If I want real speed I get a bike.

You're a GOOD GUY !! ............only the Canucks will get this !

 

[KGuy]

Loved the thread! I’m actually going through this same situation right now. It’s with a buddy of mine, but he’s a major trash talker and one upper. Talking about how his car is super fast and when I told him I got my car, he complimented it and right away started talking about how he’s faster and will gap me, yada yada yada. He even started bringing it up in a group chat with other friends how his car is so much faster stock and how mine is a phony, how he won’t even use launch control (we both have RWD fwiw) and will give me a head start just to keep it competitive. Straight trash talking. I finally said let’s go - stock vs stock (neither of us have modded yet) and he just laughed at me and made some more jokes.

The only difference is I drive an M340i and he has a new GT. I told him what I have, and he swore to me I just paid for a basic 3-Series with extra stickers and he eats those for lunch.
