It seems you do considering you continue to draw up these replies trying to cover your tail. But, since you seem convinced that you knew all along about the car, despite that your earlier post says otherwise, I'll just be the bigger man & let you go on believing you know more than you really do.

You like turning around arguments dont you... OF COURSE I know about the F50 GT1... That comment did not have any other intention then to be sarcastic. I know what the car sounds like, I know its epic... Believe it or not I know how Youtube works as well... And covering my tail? I'm not covering anything... I was merely explaining myself to someone who misunderstood the meaning of my "silly" comment.... Learn from Weinerschnitzel... he knows whats going on and so does speed junkie... But for some reason you found it necessary to come and make smart ass comments, treating me like some pimple faced teenager who love farts cans. That says more about you then it does about me... The Bigger man??? You mean bigger head with all the arogance coming off your posts...... you just keep believing that you think that I know less about cars then I say I do.... It doesnt bother me... You can feel nice and safe saying stuff like that from behind a keyboard... I was the same .... when I was 13.... Now if you REALLY feel the need to continue this nonsense, I'll happily answer you through PM....

Because you know, race cars require giant sets of fart cans to be or sound this fast.

Wow Im shocked about the low torque on this car. Reminds me of the rotarys but we still kick 🤬 at the track.

 

[Glubags]

^ Relatively low displacement but high revs generally equals way more HP than torque. It's a good thing the car hardly weighs over a ton--it won't need much torque to get moving.

THMotorsport's new track car.

Function over form.. I'd really want to see an airflow over that car to see if that kind of difusor really has function..

Why not function AND form. Either way that thing is certainly very little of the first. I explained it before. It is not a diffuser. It's taking whatever flow that goes underneath the car and uses it in the same way a wing would, which is not how diffusers function. And I'm not even going to get into how much drag that thing makes.



Also, I agree with Blitz187. I got that he was being sarcastic in his post regarding the exhaust.

It has less to do with low displacement (the F50 GT1 has a 4.7L V12) than it does with how that engine achieves that displacement. In the Ferrari it probably has a very short stroke but larger pistons and of course the fact that it has 12 of them. And just like in the S2000, the reason they don't produce as much torque as some people may want (no pun intended) is because of their relatively short stroke which is also one of the main reasons why it can rev to 9 grand all day long without a problem. The F20C, that is.

Because then you're limiting your "speed"

 

[Glubags]

It has less to do with...

Eh, you're a little off-base, but it's a good point to bring up.

The bore/stroke ratio has more to do with safely achieving high revving speeds than the production of torque itself; i.e. a shorter stroke isn't going to produce inherently less torque than a longer stroke. For any given bore and compression ratio, a shorter stroke produces less friction and is more easily spun to faster speeds, but the torque numbers will be roughly the same.

It really comes down to displacement and RPM, like I originally stated... the fact that so many oversquare engines produce higher HP figures than torque is simply because they are easier to design so that they safely spin faster (and HP is just a function of torque and RPM). Take the B18C; it's an undersquare design (stroke is longer than bore diameter), yet it can be (and has been) revved to the sky to make very high HP numbers without a massive torque increase. Bore/stroke ratios only limit maximum safe RPMs. In a roundabout way they affect torque, but only insofar as their effect on RPM. Displacement and RPM are the primary keys here.

370Z's are a bit out of my price range, but I've been holding off the temptation to purchase a 350Z. I want one so badly. But I love having no car payments at the moment.

 

[homeforsummer]

That 370Z reminds me, I took a few pics of a Nismo variant when I was in Abu Dhabi at the GT1 meeting:

Still can't get over how vastly better the 370 looks than the 350 did. The 350 wore thin so quickly.

Edit - Just not worth the effort. Ignore.

 

[Keef]

What on earth are you arguing about McLaren, you're the one that got all pissy when he made a joke about the Ferrari's weeny exhaust pipes. I thought it was hilarious; you thought he was an idiot.

 

[McLaren]

As above, ignore.

 

[Horde_R35]

Damn, im late to the party !

can we see more of the 2 above??

For any given bore and compression ratio, a shorter stroke produces less friction and is more easily spun to faster speeds, but the torque numbers will be roughly the same.

I don't know a great deal of in-depth info on the subject but there are plenty of example where an increase in stroke will increase torque, in fact I can't think of a time where this simple modification did not produce those results. Honda going from a 2.0 to a 2.2 being the first one that comes to mind.

Take the B18C; it's an undersquare design (stroke is longer than bore diameter), yet it can be (and has been) revved to the sky to make very high HP numbers without a massive torque increase.

The fact that the B18C can rev so high is because they have such well balanced cranks, as well as the rest of the engine being such a great overall design. And you don't really gain much torque by increasing rpms either.

This is quite a long article but you and anyone that is at all interested in engines may find it to be well worth the time.

Because then you're limiting your "speed"

Things that are designed with every aspect of their performance in mind and are made to be as efficient as possible have "form." When "form" is non-existent it is usually things that are designed with a "good enough it works" attitude and with not as great resources and knowhow.



And at the whole "raise you this" thing....

I know this is not a road car but I'll throw it in there anyways

I see those and raise you this...

I have no idea what's going on, but it'd be cool if the Switzer GTR really was this fast. I've read comments about the Veyron having a computer slow it down when wet, the Veyron driver letting off at different times, and the GTR having nitrous. Either way the GTR sounds great . And the Veyron looks amazing in white.

 

[speed junkie]

Yea they hold those races somewhere in Russia. The setting already looks Russian with random architecture of inhuman scale in the middle of nowhere from the cold war era which, personally, I think is awesome. And yes, that GTR does sound fantastic.

...and of course, the text in the video, which is rather a giveaway to it's Russian origins

Impressive video though. Would be interesting to see in the dry, if any of those rumours are true.

 

[Blitz187]

I just watched that GTR clip, but with no sound (at work).... Did you all see that GTR pull away from the Veyron there at the end?!?!? Whats up with that?!?!

Function and form? It's formed by function, but that's not making it look good. As you said, it's not like a difusor and surely doesn't look like one. Airflow like a wing, yes, but like this I think it loses alot of speed.. For what's the car built for?

^^^ I like the white GT-R in that clip... keeps up nicely with the Veyron til about 200 KPH... then the Veyron is BYE BYE!!!!

 

[speed junkie]

I would like to see some photos of that white GTR. I like the wheels on it as well.

 

[Blitz187]

I believe the side skirts are from the Tommy Kaira GTR... The wheels Im not sure... They look like the ones on this car though...

 

[Glubags]

Honda going from a 2.0 to a 2.2 being the first one that comes to mind.

Haha, ok... clearly we're on two different pages here.

To be perfectly clear, that's an increased stroke without a change in bore; i.e. more displacement. The extra torque is due to the extra displacement, not the longer stroke. If Honda were to have decreased the bore diameter along with that lengthened stroke to keep the engine 2.0, they'd have come out with an engine that probably wouldn't spin to 9k rpm as reliably, and it would have roughly the same torque (more likely less than more due to the increased friction of the longer stroke).

Torque is all about displacement and compression ratio. More displacement + higher compression ratio = more power. It's really that simple. The length of the stroke is just a means of achieving displacement, just like bore diameter.

Such a nice display, ruined by the lights, spotlights work terribly with cars.

 

[Glubags]

By the way, that white GTR is on Dymags.


Couldn't find any better pics of that specific GTR than this one, from the dragtimes.info blog, which obscures the wheels completely:

But here's another white GTR on the same wheels. They're full carbon composite rims with magnesium centers... VERY $$$$$:

Edit:

Here we go... clearest still I could get of the wheels from the 1080p video:
