Andre Marziali Knox Hillclimb 2018 - King of the Hill - 1:50.040
มุมมอง 2.8K6 ปีที่แล้ว
My fastest run for 2018, and FTD. Clocked at 177 km/hr into the speed trap at the first turn. The run was hampered a bit by oil on track from turn 3 all the way to 6. The car is a modified 1999 BMW M3, Supercharged, lightened to 2200 lbs, making about 500 whp. Shift lights blink at about 8000rpm, redline about 9000. This run ended my weekend, as somewhere near the end I sheared the key in the c...

Amazing car - again courtesy of a very generous friend and alumnus of UBC Engineering Physics. 670 WHP, amazing grip and downforce. Note that the shown acceleration axes are incorrect (not calibrated). Best lap of the day, though on pretty old tires at this point.

New SP4 Record - Andre Marziali, Knox Mountain Hill Climb 2014
มุมมอง 8K10 ปีที่แล้ว
My best run, and new SP4 record of 1:55.1 from the weekend at the Knox Mountain Hillclimb 2014. 1999 BMW M3, SP4 class, Twin Screw Supercharged 2.8L inline 6 cyl, 2600 lbs. Hoosier A6 tires.
going to school on youtube is awesome. i love being able to rewind the teacher and play it twice, i also get to smoke during a lecture, its really under rated. i bet more people would go to school if there were classes with smoking lol
this video is awesome im going to watch it at least twice... plus rewinds
Bravissimo!
Tolookinto whether 4 sided ground effect like thingy makes sense 4 point for each pssht no sidrd ron bc lets u drasticall psssht.... ???
Compare this with rally line andnu will understand and that neither lien is aprticularly gud ron haha KEKE ye the pssht
Let me gouys u ones uungligns give a tip only that one she said KEKE, so we have 4 wheels independenlyy and a tire that is very slippy sidesways ehrtcanwrdo? ??? Ye high torque on each veeeeery quick response so bo ice farbauge KEKE
I will in a year or so EXACTLY a year ron have a selection of race cars (I'm not talking about shmock poofter veyrons and so on, but real race cars) if you are interested in a soiree on the tracks KEKE 🏳️🌈❤😂🎉😢😮😅😊🏳️🌈🥑🍆🍆🍆✡️🤤😽💍💎🥰🔋🤤🤤
Laptimes so hard to beat it made me watch this video😂😂
what is the cool video at the end
What about speed racer 2008

54:30 So does this mean that downforce has diminishing effect?
I suppose in a sense the answer is yes - increasing downforce increases the normal force on all tires which will slightly lower their friction coefficient. Having said that, increasing downforce comes without any expense in terms of the mass being accelerated laterally, so any increase in downforce is always a direct gain in lateral grip no matter how much the tires are loaded (within sensible limits).
You’ve convinced me to get lowering springs. My wife would like a word with you 😅
🤣I'm happy to explain to her all the reasons why this is very important for your well-being
Understeer occurs when the front is heavier If that's the case, lift-off oversteer occurs when the rear is lighter can you explain this teacher?
I hope brotha monetized his channel.
1:31:56 As soon as you said "cattle grid", I immediately knew you just showed them a clip of Ari Vatanen scaring the shit out of his copilot.
The most in-depth, informative video on weight transfer I've ever seen. And I've been studying the craft for some time now. Thanks mate, much appreciated. Will allow me to dial out some minor issues.
Excellent lecture! Thank you so much for recording this.
I only absorbed around 20% of what he said but I managed to get 4secs off on racing simulators just by watching this. Awesome video.
good, focus on braking points. That's where noobs lose lots of time :)
To an American, accuracy means being within inches, not feet. But as a highly sophisticated European man accuracy means being within millimeters, not inches.
As an American, noted 🤣
Thanks for cutting out the most important parts.
just thank you man
this man helped me shave off 2 seconds off my PB on barain
My entire vehicle performance module in an hour and a half. Amazing lecture
i wish my physics teacher was this cool
1:31:55 TH-cam: Ari Vatanen's huge near miss! In Car Manx Rally 1983
The only lecture i will pay attention until the end😂
Just for me: 19:41
I've never seen an individual with such an intrinsic grasp of fundamental physics and racing applications. Why you recommend this to me 5 years late TH-cam?!
I had a few questions that i’ve been scratching my head over if you don’t mind me asking. By the way, such a gem of a video! i’ve watched this a million times mainly because the more i watch the more i understand and also because my experience and understanding grows in life. - Why do we not want negative camber or grip in the inside tire because its pushing the opposite way? I think i’m missing something and couldn’t wrap my head around it. - Trailbraking gets more normal force in the front without mass change but lateral load transfer doesn’t have mass change as well with increased normal force. Why are they not both desirable? - Last one’s regarding the stiffness of front or rear axles. If we stiffen front axles, it handles more roll moment and therefore has less available grip. Is it true to shift focus of my thinking on rear axle because it handles less roll moment, it has less load on the tires therefore more grip? i iust couldn’t wrap my head around on why stiffer axles mean less grip. Thank you Professor for making this amazing video and for future videos to come. I eagerly await more and have signed up on your website as well!
Hi Devin, I got your email and will respond there in the next few days - thanks for watching!
@@Andremarziali Thank you Professor! Please take your time. I really appreciate it!
i just drive the car
This must've been exciting. Thanks for including a friction circle and your throttle/brake input data as well!
It takes the physics knowledge of a true messiah of engineering to drive at such high speed using inverted steering 😂
if you also can't finish this lecture due to the constant mouth smacking do not feel bad. You probably also noticed how boring and uninspired it is as well.
I wish lectures are like this when I go to uni, I love this typa lectures
'and with wreckless use of an angle grinder, ive removed about 1000 pounds, from the car' lmfao im gonna love this
Very good job. Most of it was a review for me but i learned a few things in regards to car setup. I am Engineer whom loves physics and math so i found it very enjoyable. My race car experience is a handful of autocross tracks and the Gran Turismo video game. You referenced Carroll Smiths book "Tune to Win" at 53:51. His books (Drive, Tune & Engineer) to Win are excellent too.
1:17:14 "frequency thing was developed for passenger cars it is a transmissivity issue as far as i can tell" It matters like life-death difference in any car on a poorly built road. Humps that align in a sequence that resonate with any of your car's axles in a corner will show you what it's all about. Try some former soviet block country "highway" at big speed but be prepared (have your will written and signed beforehand). There was a police released video on YT from a crash scene in Hungary where two boys in a Huracan filmed their accident. At over 300 kph the car hits the humps (not even in a bend) - they flew off and died.

As someone who already knows a lot of the physics, there were some important insights here that I hadn't ever considered, especially about the transitional stage where you're trail braking and releasing the brake. It had never occurred to me that because the front springs are still compressed as you release the brake, you're still benefiting from the increased front traction and the lack of braking. That's why that instant of release creates such a strong turn-in, and it's really important in off-road racing where understeer is a big problem. Getting the timing of that brake release right is how you get the Scandinavian flick to work as well. I'd love to see an expert discuss the specific issues as they apply to off-road racing. There are a lot of questions I have particularly about spinning tyres and side bite on a loose surface. Contrary to tarmac racing, sliding is much faster on loose surfaces.
(01:06:00 _et seq._ ) For the mention of the desirable characteristics of positive caster angle, you do not mention its effect upon anti-dive configuration. Is this pertinent?
It is pertinent indeed. I've left a lot out of this lecture, including anti-dive and anti-squat. I know it's nearly 3 years overdue, but I'm still hoping to provide more content at some point to fill in those gaps.
Do you still AutoX in BC?
I haven't in a while - we lost the facility at Pitt Meadows so Autox is now at Mission raceway, which I don't think is quite as good (and farther from where I live). I will show up again sometime though! Just working on getting the car ready for Knox right now.
@@Andremarziali I hope to make it up to some BC event this year. Check out Chuckanut Autocross down here in Bellingham, we'd love to have you! Good luck at Knox!
@@AaronBuma Thanks and let me know if you come up to BC for Autox! I might join you for an event.
@Andre Marziali Will do!! Thank you for the video, it's a perfect technical intro I'll link people too
00:12:00
Right?
this would be the coolest class to take
YOU HAVE A MICROPHONE WHY ARE YOU SHOUTING
I was mic'ed for the video only, not the lecture hall which was very large
Haha! Add into the legend crash that it has a locked rear diff and Roger had no chance on turn 8. 😝
Lol! I didn't know about the locked diff. No wonder it was such a perfect example of understeer! 🤣
If andrew tate was this guy
I loved the old MR2. Think I saw it on the street once or twice in my life.
Alright. Now all I need is a car and a track :D
