I would say that there are short maneuvers of under 1.2 G that would cause significant engine damage...

Remember, the engine won't "blow up." But you'll get a small burnt smell coming from the engine immediately after the high g-force maneuver. And then you'll realize that you have to add a quart of oil every 2000 km of driving when you never had to do that before. Increased oil consumptions among others are signs of a car that was driven aggressively while turning. Sure, drive a BMW 320d or a 320i and nobody will care; adding a liter of motor oil every 2-3000 kilometers isn't that unusual. But let's say there are two 320i vehicles. One is driven by Grandma, and one is driven by Grandson. Both have the same mileage and the same maintenance work done. Grandson drives aggressively through the windy roads in the woods, often taking turns at high speeds and g-forces. Grandma drives more sedately. At 100,000 km, grandson has to put in a liter of motor oil into the engine every 2000 km. At 100,000 km odometer, Grandma doesn't need to add a single liter between oil changes.
The BMW S65 and S85 (the V8 and V10 in the E9X and E60) are actually pretty good cars when it comes to auto crosses and light track duty when it comes to lubrication. But these cars have other problems with rod bearings and valve timing issues. And every S65 and S85 owner who attends autocross or track events probably knows to replace their oil at a frequent interval on these cars. I guess my point is that the other problems of these engines are so significant that the oil starvation issue is overshadowed by the bigger weaknesses. I can't say I'm a big expert on these cars, so I default to our member Convexproblem who probably has owned one. But I was a BMW Car Club officer and I was considering to acquire one of these vehicles, so I did do some homework on them, but never owned one. Nice car though. Really like the V10 soundtrack. Sometimes I think I should've gotten an S85 vehicle.

Jaguar F Type. A car I considered.

The R is tops, of course, but a good 3.0 Engine would do the job. More GT and much heavier than an Alpine for example. Still, this body makes me dream, again. Credit; Car and Classic: Official picture. Coupé or convertible? Best, Nicolas ...  

It's glorious.

Another Ian Callum penned masterpiece. I had the pleasure and privilege to drive both the regular and R version back in 2016. Obviously, the R is considerably more powerful and sporty, but both are massively enjoyable sports cars.... Cheers, Filip

Worth getting it ....

Car had a very loose back end.

 
 By: patrick_y : November 16th, 2022-18:46
Ian Callum knows how to design cars. But after test driving this car, I immediately noticed the back end was very loose while executing a turn onto a freeway onramp. You could feel the grip wasn't sufficient in the rear during the turn. But what a beautif... 

Interesting. And sad!

Consider an Aston Martin Vantage!

The Vantage N420 (year 2015 and later) are amazing cars with a very nice steering rack (significant improvement over some of the earlier Vantage steering racks) where the ratio was changed and to me feels better. The Ian Callum and Henrik Fisker Vantage i... 

You big Tempter!!! ;)

I wonder if the older cars rattle and creak.

Agreed!

 
 By: convexproblem : November 23rd, 2022-11:35
I liked the F type exterior more than any Aston Martin, but I rented one, and I just could not get over the interior.

I've got to sit in an Alpine.

 
 By: patrick_y : November 24th, 2022-17:49
Alpine had a store on Champs Elysee but they didn't want a thousand people a day to go into the cars due to COVID. Which is fair. But that also meant I didn't get a chance to see the interior.

Next time you are in Paris.

Considered it as well along with the Cayman…

 
 By: myles721 : November 16th, 2022-18:59
I landed up turbocharging my 370Z…which had a skid pad of .98…my next logical move would have been the GTR but I think Tesla Plaid looms large unless a faster EV is released… but of all of them the Jaguar is definitely easiest on the eyes.

Liked the TT..

 
 By: myles721 : November 16th, 2022-21:54
The standard Cayman was beaten on the track by the Z and would never own an Alfa for reliability issues and of course Alpine is European..so hence there was the Z…🤷🏻‍♂️

Cayman is an excellent car...

 
 By: patrick_y : November 16th, 2022-23:21
The problem with the Cayman is on-limit handling grip isn't perfect. It depends on how you drive the car. If you're looking for something to drive on racetracks with a combination of high speed and low speed corners, the Cayman will do well on the high sp... 

Yes. I can imagine!

 
 By: patrick_y : November 16th, 2022-23:35
This is the benefit of having a double wishbone suspension front and rear. Some cars have it in the front (like Alfa 4C, but not Porsche Cayman) but very few have it front and rear (super exotics like McLaren, Aston Martin, Ferrari, Lamborghini have front... 

Thanks for checking!

Does that mean it's a wet sump or a dry sump? At the bottom of the engine is there an oil pan (which would suggest wet sump) or is there no oil pan and an external oil reservoir (which would suggest dry sump). Dry sump is better for a sports car. As the e... 

Probably wet sump.

 
 By: convexproblem : November 23rd, 2022-11:29
"Real" dry sump vs. "integrated" like on a Cayman or BMW M3 is not really a big deal IMO. The main difference is true dry sump creates vacuum in the crankcase, reducing windage loss. Even though the AM engine is dry sumped, the max power is lackluster com...

For sure, I was talking more hypothetically

 
 By: convexproblem : November 24th, 2022-17:28
The S65/S85 bearings weren't sized correctly from the factory so they die even with oil. Most engines can tolerate a small amount of oil aeration without losing the bearings quickly, and in practice you're not just doing a hard left turn long enough to us... 

The baffles do work in the corners...

 
 By: patrick_y : November 24th, 2022-17:58
The baffles do work in the corners if they're short and only last a couple seconds. If they're long sweeping corners, I'm told the baffles definitely can't prevent some oil starvation after several seconds. In either case, I like electric cars! Just about... 

I think you can corner maybe like 10 seconds before running out of oil

 
 By: convexproblem : November 24th, 2022-18:20
Which is enough for almost every track. Electric cars usually have ball/needle bearings for the motors so no need for active oil pumping. The transmission is just a usual fluid bathed gearset. It's more efficient if you have a pump that sprays oil at the ... 

Yes...

 
 By: patrick_y : November 24th, 2022-18:30
I was thinking the same thing... I hope the gears aren't literally sitting in standing fluid, that's a lot of fluid dynamic drag! But you're probably right!

The problem with 370Z is lubrication...

 
 By: patrick_y : November 16th, 2022-23:06
The 350Z was a nice car on the track. Bad brakes, but nice rear differential. If you're routinely driving at 0.98 G-force, you're going to experience engine oil starvation. Thus, for any sort of aggressive driving, I really see no way around a dry sump lu...

Issues but as the rings broke in that eventually dissipated…yes agree the breaks suck (wished they had stayed with the brembos) but I will say the taconic on NY is challenging and if I was in front it was very hard for 911’s , Jags, Audis to pass me in th...

 By: patrick_y : November 17th, 2022-01:20
I never drove the 370, but I imagine that it's somewhat similar to the 350. 350 was good. Just don't overdo the G-forces. Even BMW M3s get oil starvation problems if you take corners too quickly. For sustained high g-force driving, gotta get dry sump! Or ... 

Actually I owned both the 350 and the 370…

 
 By: myles721 : November 17th, 2022-01:29
Not even remotely the same car. Because I put so many miles on both I’ll try to be brief..,the 370 being shorter wider and lighter…much better suspension…much more rigid…wider power band…and faster (not even factoring the twin turbo) not at all the same c... 

Good to know!

Great looking “modern” Jaguar.

 
 By: RabidManatee : November 17th, 2022-01:50
Haven’t driven one. Strikes me as being heavy. I think your Alpine would be more fun to drive on back roads, whereas the Jag may be a better “GT”/highway cruiser, at least here in the U.S. Might be able to find the Jag with a manual transmission..?

Back in 2016 my wife decided it was time to bring a sporty 2-seater into our lives. She test drove Audi, Lotus, BMW M3, F Type, and then on a whim she drove a Corvette C7. The Vette stole her heart. She said that the choice was made because the Vette had ...
