Randy is that dad every car guy wants
Raptor Supercharged
*Father inlaw.
since he likes a lot of really crappy old crap, hell no
LOL THAT NAMEEE "FUCK RICERS"
@@vargohoat9950 hah. Cause old means crap.
This man needs a show or a series on YT. Could hear him talk all day
theperf3ct Podcast.
He does some good stuff with motortrend on their yt channel. On the off chance that you don't already know.
Motor Trend.
He drives for head 2 head I think
he has one now
Horsepower and Torque in Mustang definition is:
Horsepower - how hard you hit the crowd.
Torque - how far you take the crowd with you.
EDK Dude ! Really original and funny. How long did it take you to come up with that one
By Vxz I have a Mustang so I speak from experience
I like it but I think the horsepower and torque need to have switched definitions.
Hey at least youve got rwd thus hit the crowd backwards
EDK over used joke
Love the way this guy tells stories
UXXV old people always the best at telling any story
I'M THE DUDE WITH THE MR2
How's the car now?
I'll reply for him- still waiting on a new motor to go in it, but he's got the new motor at least. I'm his friend and he's not lying lol
So what happened to it? Spin a bearing like Randy theorized?
Maxwelhse Oil starved due to the sustained high g forces the bank on the track caused. MR2s are notorious to oil starve without a baffled oil pan.
To build off Rotang Klan and Velocity, yes I have a new motor sitting in the back of my Saab, I'll be dropping it off today at the shop and helping install it. Luckily Toyotas are cheap so the damage wasn't bad. The car was bone stock and had over 185k miles on the stock motor, Randy was sustaining much higher Gs for much longer duration than myself and managed to oil starve it. Had the oil pan been baffled, it wouldn't have been a problem. I'll tear the old motor apart and see what failed but it's definitely a bearing of some sort in the bottom end.
This guy is a legend, some car company should launch a special edition car in his name! :)
The Supra Pobst
The Pobst Probe...
I can see a zr1 pobst edition or something track oriented from gm
And it should shift at 4.2k.
Who is he?
I always said torque is how easily you can climb a hill and horsepower is how quickly you can do it. In my opinion that's the best way to explain it
That's not a bad example. Another is how wide a river is vs. how fast the water is flowing (works well for explaining computer processor speeds and such too since people don't understand cores and bus speed and all of that).
And this is why hill climbs are amazing. You get to hear the engines actually working.
Several years ago, I drove my then-still-new-to-me RX8 out of town. The way I went, takes you right up and over a mountain. I had that bitch singing between 7500-8500 rpm the whole way up that thing, for a good 10 minute climb on the highway... glorious noise, man.
Mrwrenchifi people confound torque with low end hp. More torque earlier means more hp earlier, but low gearing can change that.
Torque means nothing without time. 100,000,000 ft lbs over 10 years is nothing(.004 hp), but 1 ft lbs of torque at .0114 seconds is 1 hp.
Torque over time is called HORSEPOWER.
Horsepower is how fast you hit the wall and Torque is how far you go through the wall
Firestarter, YES, 100% correct. HP is a measure energy per unit time, which translates to acceleration, which is that pull feeling. Take a high horsepower low torque engine, gear it down and watch it break your neck. The truth is horsepower is the only thing that matters. However, you have to see the entire curve not peak.
To put it simply
Torque is how easily you can do something
Power is how quickly you can do it
Torque is only a momentary measurement and in turn can not do work or move you
Basic physics. Only energy can do work an applied force alone can not. That applied force can only do work over TIME.
Torque of an engine is the measurement of force.
Rpm is the time portion here.
Power is the work done.
They all work together
MyLonewolf25 better explanation than this 5 min video.
Thank you saved me 5 min of my life
My father always said that torque is the engine's ability spin the wheels of the car whilst horspower is how strong the engine ccan be. Same thing with what you say basically.
I didn’t watch this to really learn something, I watch this for Randy Pobst.
MyLonewolf25 torque is power... Horsepower is speed... If u got a car that weighs 2000lbs makes 300lb feet at 600hp that car will be slower than a car that weighs the same 2000lbs that makes 500lb feet at 400hp... Horsepower is how fast the power (torque) can move something... You can have all the hp in the world but if u aint got the power (torque) to move it it doesnt do u any good... Thats why 1000hp 4cyl are beat by 600-800hp v8s... The 4cyl dont make the torque....
Torque and horsepower are literally the integral/derivative of each other. Torque is the instantaneous force the motor puts out and horsepower is the force over time. If torque is how hard your slap is, horsepower is how many of those slaps you can fit into a given time interval. A low torque VTEC is like Bruce Lee and a high torque/low horsepower diesel is like one of those guys that flip tires at strong man competitions.
At the end of the day, the horsepower dyno curve is everything, peak numbers mean nothing and torque curves are only useful to know how efficient the engine is running while tuning.
No fuckin way I just read that. I've a test on integral calculus tomorrow morning. I took a break from studying--or so I thought. This comment might actually add a point or two.
DerekSiems fuck you bruce lee could kick like a mule.
ironman tooltime the point is that Bruce Lee doesn't hit as hard as a 400 lb strongman contender, but he can hit repeatedly lightning quick. Body weight is a big determining factor in how hard you can hit and Bruce Lee simply didn't have the mass to hit as hard as a strongman competitor. Ask anyone in boxing about it, nobody will take a punch from a heavyweight over a lightweight.
You know it better than Randy probst
Best explanation I've ever heard. Thank you!!
It's great to know Randy loves the classic Integra gsr! Those were the days when Acura/Honda was at the top of it's game with small cars like this
This guy is the Bill Nye of Motorsports
wolfgang panicali please don't curse Randy like that, even without a phd I know Bill Nye is a moron...
Let's not get carried away here...
Right on, wolfgang panicali! Learning from past mistakes is is a big part of the genius of Pobst, Neil DeGrasse Tyson, Nye, Einstein, etc.; we all f*ck up, after all. I hope bmwmdude is genius enough learn a thing or three and edit his Nye appraisal from "moron" to "BS mechanical engineer who invented airplane things and made some people laugh while they learned stuff" or something like that.
W. Bush well let’s just say he had a good show for a bit, teaching kids a lot of great things. Then went downhill and tried to misrepresent himself to the public proclaiming a false narrative of global warming or what do they call it now climate change...
+bmwmdude spit that supa hot truth
I could listen to Randy's stories all day, everyday. Vinwiki is by far my favorite channel on UA-cam. I don't know how I haven't come across this channel before now. I'm hooked.
Horsepower is a measurement of how much work an engine can do.
Torque is a measurement of how easily the engine produces that work.
Torque is a measurement of work, horsepower is how many times that force is applied over time. Eh?
How about the technically accurate definition of rotational force and rpm
Power is work per unit time. Torque times angular velocity times constant gives power.
Torque is rotational force, horsepower is just power
How easy produces work? That’s a very confusing. If I’m on a bicycle in a low gear and pedaling fast versus in a high gear pedaling slower but stronger (more torque) I will have the same acceleration. What do you consider producing work easier? To me it seems equally hard to pedal
I love hearing Randy Pobst stories. Please keep it up!!
Always nice to hear Mr Randy's passionate stories.
I'm definitely down for just way more videos with Mr. Pobst. What a dude.
So true haha my s2k has nothing below 4.5k. Even then, it doesn't hit till 6k. But damn does it pull hard to 8 (ap2). Even in 5th gear it pulls pretty hard all the way to redline. I'm not saying it's necessarily a fast straight line car but it is impressive for what it is naturally aspirated.
I love it when Randy comes on the show!
You know you're early when bitcoin dude isn't here..
legend has you can summon him by saying "bitcoin" 3 times into the mirror.
jdschley - haha, I reported him, maybe he's gone forever.
i'm here!
Why would you report me? I'm the CTO of Vinwiki. Apparently you haven't done your homework.
Vinwiki.com noobcake.
I love randy so much I could listen to his stories for hours and hours. I really hope I could meet him some day haha
This channel needs more subs, for some reason it made me
Love watching old guys tell me stories about getting arrested for doing illegal shit in cars I can’t afford with a part time high school job
I love hearing people talk about the difference between old and new engines. I drove an 89 Mustang LX 5.0 with 225 hp at 4200 rpm. It ran out of cam at 4800 rpm. Friday I rented a 2017 Camaro 3.6 v6 with 335 hp at 6800 rpm that shifted at 7000 rpm.
He finally explained the difference between the two. Thank you sir.
Randy pretty much explained why the s2000 is better than the Miata. Please do a video on this Randy!
You can buy a new Mx-5 but not a new S2000 :o
He's right, those old V8s the torque fell off so hard that even know you could keep reving it, it was like waiting for paint to dry, you might as well shift like he said... Randy is a cool guy...
Pffff I wanna see what he says about a Diesel lol. 3k redline! 2500RPM peak power!
Brap Brap maybe american diesels.
335Ds run 12s around 110 in the quarter with a tune and exhaust and rev to 4500.
Aviation piston engine redline usually 2500 to 3000 rpm coupled with gearing that spin the propeller to 20000rpm
Mercedes om606 redlines about 7000rpm,common rail beamers,MBs around 4500. Max torque on diesels are normally between 1500-2500rpm. Max hp around 3000-3500rpm.
Brap Brap Bitch quit copyin my profile pic
Love some of these stories
I have no idea who this guy is but I could listen to him all day
I love listening to Randy Pobst.
Randy's the best. Love him!
Wisdom from a racing legend! I love it
Randy for prez of everything!!! Love you Randy ❤
Nice that he appreciates different cars for what they have to offer.
You should have this guy back more often
Him and Ed have the best stories.
Torque is like amps in electricity, it's the grunt behind the current; where RPM is like the voltage, it's the pressure. Multiply them both and you have Watts/ Horsepower. Both are units of power.
kawrx2002 best one
Longer videos please.. I love them
I love the mazda 3, my mom has a base model but a few minor mods, she wants to add more, but that thing is fun to put into manual, but if you have an auto with sequential, just let it downshift for you when slowing down or you will have a very uncomfortable slowdown because it is very jerky if you downshift it, so just let the car do that for you and only handle the upshifts, I just wish i had a transmission like that in my 00 eclipse rs (I have one that has enough mods to probably put to right in between the rs and gt)
People explaining torque and horsepower wrong in 3, 2, 1...
lol yup
Horsepower is just a made up number from torque and rpm, Randy's was kind of correct
@@Doggepe torque is just the acceleration force the tires impart on the ground, and the ground imparts on car. Horsepower is the rate at which the force does work against friction and inertia.
You need torque to climb a steep AF hill; you need horsepower to climb the hill quickly.
Ergo: diesels can climb a steep AF hill, but can't climb that hill quickly.
DumbledoreMcCracken How the fuck is that an answer to my comment 😂 I know the physics dude
@@Doggepe Nope. Horsepower is a quantifiable measurement of the amount of work that can be done in a given period of time. Definition of H.P. is the ability to lift 33k pounds, one foot vertically, in one minutes time. Torque is nothing more than the amount of force applied to an object or lever. Google first, then speak.
You heard it folks. One of Randy Pobst's favorite engines is a turbo honda engine. All the V8 guys can't bag on them anymore haha. This guy knows what he is talking about.
Awesome watching this old dude go on about b series VTEC turbo... ;)
I love these videos!
Randy!!! Your the man!
Torque is the lever's length multiplied by the force applied at 90 degrees at the end of the lever multiplied by a constant to make the units fit (N-m). Power is the torque multiplied by an angular speed (RPM) and by a constant to make the units fit ( Hp).
4200 rpm shift point. I’ve driven diesels from that era that we’re still pulling at 5000 and enjoying it!
Why has this legend not been on recently
This is just a legend of a guy!
Good explanation of torque vs horsepower. I was sad he didn't get a chance to drive/break the Rotsun on Roadkill. Hopefully he drives the v8 upgrade soon :)
Not one mention of the physics behind hp and TQ. TQ is force, power is force over time. So HP always has rpms involved to give the power rating.
FINALLY! I understand the difference, thanks randy
I've been dying for a MR2 story. I only own a 91 N/A but still an MR2!
Could listen to Randy all day
This channel will be one of the biggest soon. MARK MY WORDS
Is there a build sheet for the GSR he’s talking about?
Hi.. I have some confusion with this.. I have an airplane that weighs 930 lbs. We hooked up hanging scale to the tail and ran it up to max rpm of 5600. The scale read 500 lbs... what info can I get from this..? Ft.lbs..? Torque lbs..? HP..? Or..??
I want a ringtone with Randy Pobst doing baaaaaaaaaaap baaaaaaaaaaaap
I have a good variety of different engine experiences, but my MKZ has such low end torque, that when I took it to the track I found myself staying in 3rd after a few laps (except for the long back Ss and front straightaway). I would hit a turn about 2500 RPM and ramp it 6000 before breaking the next turn.
My dad worked for acura in the 90s. He had a couple of NSXs a few legend coupes, and a couple integra gsrs (not at once over a 4 year period) and he always said the gsr was the best car he ever driven lol! I learned how to drive stick in a legend coupe 6 speed. Good times
I can listen to randy all day long
My favorite engine is the 1LR-GUE by Toyota. It sounds amazing with the stock exhaust.
Randy's selfies are the best lol
V6 ,1987 fiero gt comes on from 4500 to5000 .3 td gear on a circle track. Most fun I have had in a while.my wife was pinned to the passenger door in the turns. New Smyrna speedway, fiero 2015
A lot of little turbo cars have lots of torque on the low range, which is good for daily driving since it always feels like it has good power, it might not be the most satisfying driving on the track though because you don't get the feel of growing power quite as much at the higher revvs. Although with a big turbo you get that for a bit as soon as the boost comes on.
I had an 82 Saab 900 turbo, great little car. No torque or horsepower without its little whistling turbo (I think turbo lag was defined by this car....). But, once that whistle started, it was great fun, it pulled hard from down low to high. I always said, it was fast, as long as you were patient. I learned how to launch it hard by pumping the gas (rev, rev, rev...) and then dropping the clutch. I called it hyperventilating it - I suspect the waste gate didn't act faster than me building boost by doing this trick. Note, just holding the gas wouldn't work - that just gave the engine momentum and a kick to the clutch, but no boost until a pull started. So hyperventilate it! One day I found myself behind an S2000 at a stoplight, in a merge lane. I recall an article where an editor short shifted an S2000 (ahem, at 6k...the Saab redlined at 5500...) and it went from a 14 second quarter to a 16. Well, my Saab would run low 16's, so I looked for the day if I could catch an S2000 owner not willing to rev it like he stole it, and I would have a chance. Maybe this was the day. It was common for the only people to be in that right lane to be those willing to jump on it as in maybe an 1/8 mile, you had to merge. I waited, but readied the Saab (rev, rev, rev....). Light changed, the S2000 took off, and yep on it - me too! I hit 2nd and hard on him. Then the S2000 shifted - I knew it was early and laughed - this was my chance. We both had the left lane beat, and I was already in second and, not lifting on his shift, swerved and came around. I went by with a big cheesy grin, as his cams came on and started catching me again, but too late - I captured the pole. He caught me right away, but, alas, was behind. My one and only chance - stole it. Torque versus horsepower. You got to know how to use whatever you've got.
Randy, from a fellow glasses wearer, what kind of specs do you race with? How do you cope with loss of pereferial vision from the arms?
@0:15. When Randy said what he enjoys at any track day. And then he says “bumping into people...” I thought Randy was gonna say bumping into people and running them off the road. LOL! 😂 I was gonna say... Randy a Savage! His New name should be... “Randy Savage.” LOL! 🤣
Just Bahhhh Bahhhh!
stangkiller1789 the ting goes
Those mercedes rims in the background tho
This guy is a legend
I love Randy's car reviews, and his passion, and his comprehension of what's going on with everything between the man and the asphalt. And yet...I'm confused at the examples he used. I'm not confused about the individual examples--each of them made sense in their own right. But why he chose the ones he did, and most importantly, what was he trying to convey overall at having chosen those examples? He cited muscle cars with high torque and low revs and how you can pound the pedal at any rpm and you GO. He cited the little turbo Acura/Honda engine that [once you got the RPMs way up in the statosphere] went like a demon. So there are two extremes on opposite ends of the spectrum. But then he "picks on" the Mazda Miata...Instead of Mazda tuning it for a higher peak RPM to boost sales, boost bragging rights, and persuade (require) their Miata owners to ring every last RPM out of them to be able to enjoy them, Mazda has (not only in the Miata, but in other cars as well) attempted to give a MORE USABLE power curve by bringing the torque on earlier, and sacrificing that "advertisable" and "braggable" peak horsepower number. If I was building a track car (which I never have) I'm not sure which way I'd go. Probably the screaming-like-a-banshee-sky-high-rpm-maximum-horsepower-at-redline route. But for a car I have to drive every day, in the city, on public rural roads, just trying to find some fun in my daily commute, and trying not to grenade the thing with the requisite constant redlining, I choose the mid-range torque every day of the week and twice on Sunday. I'm no Randy Pobst, but I've driven a LOT of cars over the last 30 years, and in particular, I've driven TONS of affordable cars for everyday dudes with responsibilities, limited time, and very limited budget. And for me personally, the cars with more midrange pull and less high rpm excitement were FAR more satisfying to actually live with in real-life, public road driving than the high rpm screamers that had to be wound up to have fun with them. But that's just me. That's not right for everyone. Each person has different needs, different budgets, different types of driving circumstances, and different things that turns him on. So what's best for me obviously isn't best for everyone. No problem there. But I don't know Randy would pooh-pooh a car or manufacturer that tries to find a nice middle ground while singing the praises of those who try to be the best at one end of the spectrum or the best at the other end of the spectrum.
Keep em coming
I think what people mean when they say "torque" is throttle response at low and mid RPMs, or turbo response if it's forced induction. How much more power is left under your foot between where it is now and when it's pinned.
This channel going to blow UP SOON
Can you come to Perth, Western Australia and drive my turbo 86?
its +250 hp over stock and 100kg lighter than stock
Love this guy!
They shower an NC but Randy is talking about the nd1 with the skyactive D before the upgrades. Just had to defend my NC2 which does have a 7500rpm redline
area under horsepower or peak horsepower. which is better?
This fella reminds me from old wise man in Shooter
Has a cyclist more torque in low RPM? As much RPM can you move the legs, do you have more power?
Thanks :)
Power is how fast you go through the wall and torque is how far you take it with you.
Randy is a cool dude.
My example of torque v power is this
Imagine you have two road workers with two large equally sized piles of dirt and a hole to shovel the dirt into.
One worker is given a small shovel, and the other is given quite a large shovel.
Both workers set to work on shoveling their pile as quickly as possible,
The worker with the small shovel can move quickly and repeat his action quickly, but moves little material per revolution, (high power/low torque)
The second worker (with the large shovel) moves slower but moves greater amounts at a time, and after a short while, he tires from the work load, (high torque, low power)
You see, power is a measure of the ability to repeat a process and is the function of torque (turning force) and rpm (speed)
If the second worker grows a bunch of muscles and can utilise the large shovel for longer and quicker and can manage over heating and has a steady flow of food (fuel) to keep him going he will have high power and high torque.
We met Randy at AMP, super nice guy. He needs his own series or they should make him the driver in the new Top Gear
Let's all drink Pobst Blue Ribbon!
love how car guys dont know a fucking thing about hp and tq and still are proud to be on camera showing it
Best way to explain this is to know at what RPM the car is making peak torque. If you have two engines and one makes twice the torque at a given RPM (let's say, 2,000 RPM) it ALSO makes twice the horsepower at that RPM. In this example, this car would be quicker off the line and pull harder/more weight if you're towing. An engine that makes twice the torque at 6500 RPM is going to want to pull all the way through the gears and will eventually make much more horsepower.
God bless this man yo
ND2 corrected the reving fun for the Miata with the uprated 184hp engine
You teach them Randy. 😁
Bring back Randy
Great vid. But no such thing as an Iroc-z in 82’ only had the z-28
Horsepower equates to how fast you can go. The speed in which your legs run, Torque equates to the muscles in those legs and the pushing force they create to get you their.
This dude REALLY needs to consider becoming a racing driver. It sounds like he really enjoys driving
He is a racing driver.
Torque = How much potential to do work exists (FtLbs of energy).
HorsePower = Potential energy converted to kinetic energy through use and derived from time(how long the FtLbs force is being applied = power 💥the distance the car moves = work ).
You need torque to climb a steep AF hill; you need horsepower to climb the hill quickly.
Ergo: diesels can climb a hill steep AF, but can't climb that hill quickly.
Torque is just the acceleration force the tires impart on the ground, and the ground imparts on car. Horsepower is the rate at which the force does work against friction and inertia and gravity.
Is torque and moment the same thing?
Even the legends know that for small motors not many out there pull like a Honda especially NA with Kseries making 250-300hp now a days. Or 500hp NA if you’re pockets are deep.
I thought IROC-Z wasn't introduced until 1985?
This explains why in old American muscle cars you go faster shifting at 4,000 to 5,000 rpm rather than thinking that high revs are your friend. Those cars always had crazy torque compared to Horsepower.
i never wanna hear any shit about my boosted 99 civic si anymore!!!!!!
JDM Cesar people know honda makes great engines the ricers just give it a bad name
FREE WILL DEFENDER Rice is delicious until those idjits burn it, and the stanced fart-can pot they burnt it in.
