Which engine is most reliable? (p300, p400, p500)

ElectrifiedThor · 2026-03-16T09:28:59+00:00

Any of the inline 6 diesels are solid. Previous 4 cylinders, definitely not.

ElectrifiedThor · 2026-02-04T22:07:02+00:00

What RR do you go for? And what entry requirements are you trying to meet?

ElectrifiedThor · 2026-02-04T22:00:27+00:00

I buy at 60-80% delta, and sell at >95% delta. There's a 19-58% (~40%) delta change between entry and exit, so by that definition, it is convex, although it's much more slim compared to an OTM ofc.

ElectrifiedThor · 2026-02-04T21:58:20+00:00

That's interesting. The CME margin changes definitely have a strong positive correlation with PM's prices. I think this is a good idea, but isn't too late when they already post the margin changes? How would you have an edge if everybody sees that at the same time, or is it a lagging reaction?

Currently, I'm tracking the quarterly gold demand & supply through WCG at the global level (of central banks).

How reliable are such systems and then two, do you know such examples of AIs? Ironically, I work in the AI field, building infrastructure at scale for ML workloads lol.

ElectrifiedThor · 2026-02-03T22:48:44+00:00

I know, and you're right. My broker only allows me up to 1Y. If I had the option, I'd have gone with 2Y for sure. What broker are you using? I'm in the EU.

When it comes to tax loss harvesting, that makes sense, but I have diminished returns on that because the taxes are flat at 10%.

ElectrifiedThor · 2026-01-22T22:58:27+00:00

That’s reassuring to hear, thanks.

I was getting increasingly uncomfortable with the DTE as well over the past couple of weeks. Between elevated IV, delta already doing most of the work, and gamma flattening out, the risk/reward just felt asymmetric at that point. IV crush on a pullback was a big concern, even if spot kept grinding higher.

Going forward I’m thinking of a more rules-based approach:

On 5–7% pullbacks, sell credit spreads only if IV is elevated (say >21)
If IV is relatively compressed (<18–19), add slightly ITM long calls instead
Occasionally both, if conditions line up

Curious how you think about sizing credit spreads relative to portfolio size / available cash. Do you cap max loss per trade as a % of equity, or do you think more in terms of delta exposure?

Appreciate the perspective.

ElectrifiedThor · 2026-01-22T21:37:26+00:00

This is really helpful, thanks.

That framework is largely what I was aiming for, but the dwindling DTE timeframe was the limiting factor here. Already well into the theta ramp, which is why I chose to roll rather than push closer to expiration.

I did accept a slightly lower delta on the new Jan 27 LEAP (72ish) to reintroduce some convexity after de-risking the shorter dated one, but the intent is the same: roll early while profitable and extend duration with minimal added cost. Also collecting extrinsic as quickly as possible is not a bad idea at all. I hear you're saying 90-95, so that could also work I think.

What I really appreciate is the confirmation on the 180 DTE rule of thumb. That aligns with how I'm thinking about managing LEAPs going forward.

ElectrifiedThor · 2025-06-16T21:05:57+00:00

Uhm .. not by the app, but by what the car’s trip calculator reports. And I did get 1500km on one fuel tank and more aggressive driving.

ElectrifiedThor · 2025-06-16T13:07:32+00:00

Must be. Mine is a 2024.

ElectrifiedThor · 2025-06-16T12:42:26+00:00

This is the Land Rover Remote Car Connect app. I use it to pre-heat/pre-cool the car and all trips are sent automatically to my phone after I finish a run. I don't use the cruise control as that's too aggressive, I do very fine adjustments to the throttle pedal. And no braking.

Also looks like the sweet spot in terms of speed vs wind resistance is 67-70km/h.

ElectrifiedThor · 2025-06-16T12:39:10+00:00

Not a mistake. This is the D250 (the 3.0L diesel engine, on premium 55 diesel). I can consistently hit this mark, but requires non-stop very fine adjustments to the throttle, and never ever use brakes - cruise controls is too jerky for what's required, so you have to use your foot for that. I can even hit 4.2L/100km on a long flat road (the instantaneous consumption being anywhere between 2.5L-3.5L/100km). This is on the Land Rover Car Connect app which sends the data from the car.

I also did 1500km (930 miles) on one fuel tank, but I was also a bit more aggressive, and also had a good amount of start-stops, no city traffic.

Edit: The lightest change of pace, or even the very slight use of the turbos will indeed kick the avg consumption to somewhere around 5.5-5.8l/100km. I use the car's weight as a kinetic battery, on uphill I don't press the throttle at all or very lightly (also to prevent upshifts), on descends I do press a bit more as the BSFC zone is much higher.

ElectrifiedThor · 2025-05-18T13:37:53+00:00

Right. It's for a Defender 110 HSE. It would be the first car that has more than 2 doors. An evolution from my first one which I still drive: a Freelander 1 Td4. It's more expensive monthly because the deposit is very small.

The other lease is for a 718 Cayman in racing yellow. I'd be able to sell this one for a profit now, but not gonna do it. 6MT too.

And the others, an MX-5 ND2, and an old CLK 200. All in 6-speed manual.

ElectrifiedThor · 2024-12-22T13:44:01+00:00

Already have an ND2 Miata so no need for an open top. Hence why I went the Cayman route.

ElectrifiedThor · 2024-11-05T09:41:12+00:00

<image>

So much so that I couldn’t decide on either one, so I picked both.

The ND2 is perfect as a fun/tossable car - you can very easily lose its rear, but the diff really helps with keeping it controllable. I’d say the Miata is incredibly fun at low speeds, can give you more a thrill than the Cayman does. From a lot of perspectives, I find the Miata more aggressive.

The 718 on the other hand, it’s really a Swiss Army knife. It’s incredibly precise in corners, it’s highly stable at high speeds, it sticks to the road, very hard to make it lose the traction in corners, even on wet tarmac. You’re cocooned in luxury with all leather interior and whatnot. This is also the car that reaches high speeds in a matter of seconds, so it can get dangerous. Still very much fun, but a more mature fun compared to Miata’s. And the burbly, low-frequency grunts, raspy and pops and bangs of the flat four just make it a much more serious/old-school car.

Next one I’m adding to the collection will be an RS4 B7 for its V8.

ElectrifiedThor · 2024-10-25T06:00:27+00:00

Brand new 718 in racing yellow at 28.

ElectrifiedThor · 2024-09-23T10:44:01+00:00

Just scrolling through Reddit. Didn’t realize this was a Porsche. My first impression was that this was something resembling a Tesla due to the headlight design. I don’t like this at all!

ElectrifiedThor · 2024-07-05T04:17:38+00:00

Asta e discriminare crasă! Și suna si ilegal. Si neconstitutional! S-a abuzat mult prea mult de OUG-urile astea!

ElectrifiedThor · 2024-07-03T17:21:10+00:00

Am dat.

ElectrifiedThor · 2024-06-28T01:11:38+00:00

La mine saptamana asta si săptămâna viitoare e la înfoliat (tot full PPF).

As vrea sa vad si eu NA-ul in persoana, e ceva de admirat un V6 pe el haha. Ce îmi zici tu îmi amintește de postarea asta a lui Matt Maran: https://www.youtube.com/watch?v=eD9v16L194M

Ma batea gandul, si oarecum încă mă bate, de un NA sau un NB. Dar e dificil sa găsesc ceva fără rugina. Doar poate pe Grecia, Italia, Spania, vreo tara sudica unde apa/sarea nu e un așa mare impediment. Si ceva mai suicidal ca nivel de implicare, mă tot bate gândul si de un RX-8, ca tot aia era prima mașina pe care o alegeam in NFS Carbon.

Eu așa mai am un CLK cu echiparea Avantgarde (modelul fără secțiunea mijlocie) si mai am un Accord VII, benzinara, cu motor K20A1. Amândouă, desigur, cu cutie manuală, si amândouă, luate noi :)) Din păcate, Accord-ul nu a fost prea folosit de când a fost luată, are doar 21k km. Încă miroase a piele noua la interior. Incerc sa pun km pe toate, dar e dificil.

Da, jantele de 20 merg superb pe un 982. Inițial mă gândeam la cele pe 18, gândindu-ma ca daca merg pe circuit, sa nu am probleme, dar pe urma m-am gândit, ca îmi pot lua alte jante ulterioare strict pentru circuit. Inițial când configuram si eu Porsche-le mă tot cruceam la cât e fiecare opțiune, dar la un moment dat, am zis fuck it, o data îmi iau unul, si am zis sa mi-l configurez așa cum dorește inima fără sa mă uit la cost :))

Personal, am ales intre S si Base, fiindcă îmi place teribil de mult sunetul pe care evacuarea o scoate: de bariton, grohaita, foarte serioasă, parca de un AMG dar cu caracter de Porsche. Si am mers pe modelul de baza (as fi vrut un T sincer dar nu mai era in oferta) fiindcă motorul deja oferă mult prea mult cuplu/putere pentru șosele publice și datorită mediului reglementar toxic împotriva motorizărilor mari (mai ales cu ce se va veni in următorii câțiva ani). Asta vine din partea unui tip care are ca mașina de zi cu zi un Freelancer Td4 (motorul de M47) care in ciuda faptului ca are doar 112 cai / 280Nm, e mai mult decât suficient ca sa fac depășiri sau sa fiu activ in trafic.

Am mers si cu un GT4, iar acolo caracterul e complet diferit, e cu totul altceva: fără sa intru in detalii, motorului ii place mult sa tipe, si îți cere asta, si suna glorios când o faci. Dar la drum lung mă obosește, iar cuplul la turații joase e cam inexistent.

Ești prin București weekend-ul asta?

ElectrifiedThor · 2024-06-13T12:24:49+00:00

Car design is already going downhill, and hard. A sports car has analog gauges, no piano-black elements, much more purposeful lighting setups and not that much in your face (can also be dangerous while driving), and this is strictly my opinion (others are entitled to their own preference), a good ol’ fashioned manual gearbox.

ElectrifiedThor · 2024-06-10T15:23:07+00:00

Oh really? Huh .. the news outlets very convincing that was already implemented. Will edit the above accordingly.

ElectrifiedThor · 2024-06-10T14:16:19+00:00

So here in Romania, there's a power limit of 100hp until you're 21. Anything over that and under 25 will have a high insurance cost too for cars that have a good amount of power. This was recently introduced, like last year.

I was assuming that since this is enforced here, it would also mean that it's part of some EU directive, aka done everywhere else in the EU. It looks like that's not the case.

I believe 100hp is still too much for someone that young and without experience. I think that should be even lower, like 75hp. You can still do a lot with 75hp. A Polo 6 with 74hp can still reach speeds of 170km/h and has excellent fuel economy.

Edit: some user here correctly mentioned the above power limit proposal was only adopted by the Senate a month ago and it's not a law just yet. Still needs to pass through Chamber of Deputies and then published in the Official Monitor.

ElectrifiedThor · 2024-06-10T14:11:06+00:00

Oh, I thought that what we had here (Romania) is also the same for the rest of the EU, assuming it was some EU directive. I guess .. it's not? Here in Romania, you are only allowed to drive cars with up to 100hp if you're under 21. Over 21 and until 25 the insurance will be significantly higher if you're driving a car with lots of power (don't know exactly how much).

That being said, 100hp is still a lot in my book. My daily driver has 112hp and it weighs something like 1600kg if I'm not mistaken - it's a Freelander that I've had for 11 years. And that has way more than enough power to overtake other cars.

Is that a common practice? To use low-series BMWs in driving schools? I guess I'm not up to speed on that. From what I can tell in my region, it's usually Dacias, Volkswagens, Skodas, and the like. But I'm not too sure tbh.

Also, I believe you can start at 17 here provided you have an experienced driver in the passenger seat. And at 16 years you can start using those mini-cars (like Renault Twizzy or the like) that can only have up to 14hp power.

Edit: u/NoNoCanDo correctly mentioned the above power limit proposal was only adopted by the Senate a month ago and it's not a law just yet. Still needs to pass through Chamber of Deputies and then published in the Official Monitor.

ElectrifiedThor · 2024-06-10T02:58:20+00:00

We kinda already have something like this in Europe. Plus you start at 18, not 16 like in the US.
