Cool guy, cool channel, subscribed. This guy knows his stuff and he isnt condescending when explaining it. I've gotten lots of good info from him on lots of topics. THANKS UNCLE TONY!
What a wonderful wealth of knowledge. This is stuff most people would never even begin to think about. This is really valuable insight, and it's free. Thank you Uncle Tony.
This is a GREAT video, UC, full of advice for hidden little speed gifts right in front of us. This video was more useful than even your Cold Start Extravaganza
Had a new '67 Camero, 275hp/327, 3 speed with 3.08 gears. When the 4-speed boys hit 2nd I was still pulling strong in first. It wasn't a burn-out queen but it was quick with very little spin.
Man I swear coming from a 15 year r&r technician out of all of youtube mechanics I have seen you uncle tony deserve your own tv show at the very least another 900,000 subs !!!
7 ish feet for every time the tire spins one revolution..... That alone puts into perspective just how much tire spin affects ETs at the end of a run! Thank you for putting that so well into words!
Woah that is an awesome tip for properly inflating the tires! Running into major traction issues with my 3.73s now and I knew id find some answers here.
@@jeffcivjeep7 not entirely factory stock. He talks in another video where he started with a stripper zero option car: reduced weight, changed thermostat, removed sway bar, adjusted timing, adjusted fueling by using an electronic part from an automatic, bypassed certain accessories with a different belt, messed with stock airbox. Pretty impressive nonetheless
Sometimes I wonder if UT actually didn’t drop out of school and actually has an engineering degree. But he says he dropped out to improve his street credit
@@fastinradfordable it was sarcasm, I know that, I have a bachelors. I was simply complimenting his genius...aka you would think this guy is a full fledged, licensed and degree carrying engineer
How and when to apply all the racing methods , practices , cheats etc is cool . But can someone explain to me what side of the track is picked and why it changes all these lil titbits are so crazy . It’s like asking a trophy fisherman his secret spots where to find the fish , what lure , what the tide is doing etc etc etc. Cheers
@@mikepoint4983 one side might have a little more traction than the other, either from the guy putting prep down or whatever cars have run that lane taking it off
As that tire spins the centrifugal force pushes the center out more that's the thing to remember. When you heat the tire up the pressure increases and the contact patch decreases. Error on the side of low pressure with a radial anyway with slicks you can learn what's going on. I used to run dirt cars on circle track and heat changes tire contact patch quite a bit. Bias and radials are two different tires
Looking back on a build , I used way too light a flywheel. It would break loose and zing to the moon, and when you tried to pedal it back and it hooked ,as soon as you nailed it again it broke loose. It was fun though , when you revved it in neutral you swore it was partially siezed because it ramped up and down so fast. Same but different with the 2 stroke dirt bike guys who ride in alot of sand , they usually like to add some flywheel weight so it's not so snappy
My high school physics class had a steel hoop and a wood disc the same diameter, same overall weight. Teach put them on top of a ramp, asked us which one we thought would reach the bottom first. We all said "same time". Wood disc was first by a long shot.
@@MrTheHillfolk I can certainly see why he would want more weight on the back of the car, but I have trouble seeing why rotational weight is desirable outside of idling. The lighter tire should grab just as fast after he gets off the throttle even if it is spinning faster by the time he realizes it is spinning, because it will slow down again in less time, and the energy would help coast further, but it shouldn't help accelerate. I would focus on moving the battery back, then the radiator if possible.
@@alan6832 With a little more rotational weight the breakaway can be easier to pedal and if it does it won't take off to the moon as fast. It's a sharper knifeedge to ride and pedal it when it's less rotational weight. You're also gonna have to get in it quicker so it doesn't pull down as bad as it's starting to hook. I'd rather have it light too, all that stuff can be figured out with a little testing.
Awesome, thanks for the info, I am helping my son put together a vehicle to do some runs and the track and I will definitely be telling him this, thanks again. And I love the videos.
Flywheel effect is so heavily overlooked and in some acases disregarded .. im happy to see you bring it up and demonstrate the fact . Being a 2 stroke drag race guy im a super huge fan of heavy cranks and adding flywheel weight .. its all about keeping the momentum going the right way whilst overcoming whatever moments of inertia apply to what your doing
Your logic for choosing a 9" tire is solid, but I don't think you'd need anything wider (even with more power), granted the suspension is sorted. Here's why. I recently spectated at an NHRA event where I saw Factory Stock Showdown cars making ~1500hp pulling a wheelie on the launch and doing 7 second passes... ON 9" WIDE TIRES. Blew my mind.
Very interesting uncle tony! Didn't know this great trick to figuring a starting point for optimum psi/traction for a drag car. I bet back in the day I would have been even faster on the street as a sleeper.
That was gREAT UTG i did a ouick E this morning on my truck 25 in the back ( no load ) 34 driver front & 32 pass front rides and takes the turns So Much Better ! And yes a heavy wheel or flywheel stores lots of Energy .
If I have a buddy go with me to the track, I have them make a chalk line across my tire after the burnout. Then I check the tire after the run. It will show the contact patch
Good info UT. I like the cardboard feeler gauge technique. I also consider the psi change between a cold and hot tire. Mine were up 4psi after some spirited driving.
it makes sense that the heavier wheel will have more energy stored once it starts spinning freely. this free spinning energy will die down slower than a light rim when you lift the throttle. allowing you to in a way oscilate the wheel speed right where you want it easier. I always knew tall wall tires were "the way" this puts it all into perspective.
I feel like you deserve more than one thumbs up so.......👍👍👍👍👍👍👍👍👍👍 Ok maybe not THAT many but I don't feel right about "taking them back" by deleting them either so.... here ya go!!!!! 😂😂😂😂😂
That's basically a 4dr. '71-'75 Charger. I bet a Charger nose would bolt right up. One could even make Charger rear qtrs. fit, along with the tail panels for a 4dr. Charger. : ) Good show. Always learn something!
general rule of thumb from my drag racing experiance ...mickey thompson likes 18 to 22 psi with small burnout and good year d3 likes 14 psi and heavy burnouts ...and i also use 28x9 slicks on the fox ... cant wait to see bottle rocket on slicks and juice ...oh man thats gonna be a thrill
Tony! Any recommended tire sizes for 1965 imperials?? I would like the tallest tire I can fit. Any suggestions from previous success? I know how to measure everything. But if you have been there and done that, I would love to go with that rather than trial and error on my own. You are my hero. 😃
nice, I didn't think about the flywheel effect being more forgiving to help it scoot better on the short hop. I like your plan trying what ya got now, then some bias tires, then maybe some lighter rims after that. definitely a different ball game all over again when it gets sprayed
Talking about traction and I keep getting distracted by the dirty dirty tires. But on another point I was always told that air-shocks where bad for traction as they prevent the suspension from squatting and helping weight transfer.
Great information about the heavier wheels! Don't forget when ya do a burnout & heat up them tires they will gain a little pressure, not sure how much but I think she might be happier closer to 20 psi or less. But then again I know nothing about setting up a drag car! Hope everything works out at the track! Spoke to ya later, Ka moan.😎
@Michael the MAN What are ya new here Mr. Painted toe nails! Read the whole comment before opening your big mouth & the crap starts flying out! Yeah, I heard him say startin' point!🙄🙄😲🤪
Interesting concept. It has got me thinking, obviously the higher weight wheel takes more time to spin up but it also takes more time to slow down. If breaking traction is due to the surface of the tyre moving faster than the surface speed of the road. We pedal it to slow the wheel down in order to re-initiate traction. But a heavy wheel will take longer to to in-itiate traction because it cant react fast enough. So wouldnt it be more effective to only use heavier wheels on the none driven front wheels which are slave to the road speed, and then use to light wheels for the driven wheels which need to the lightness to be more reactive to changes. The front wheels still would have inertia and thus still propel the car due to invested energy.
Hey John love everything you do,how do we post videos on hear I have a few good ones of some really good street racing I do would love to show how hard my car hooks on the street with a stick
It's been years since I dragged myself, but I have never purpose bought new stickies for the track as I don't go often enough to justify the $- so when you buy used slicks etc they aren't always the ideal size. In any case, I ran a 1/4 mile with my 350 swapped S10, with 3.73's and 28" tall tires I was only taching 4300 in the traps- I acquired some 26x9's on 16" GTA trans am rims (light) and the next runs I was right at 5200, which is where my mis matched combo peaks and falls off over that.
Not only does the inertia of the wheel help with traction, that unsprung weight is free grip as well. Dirt track guys run unnecessarily chunky brackets on their rear ends for the same reason.
Good stuff. You should point out that your math is 9"- (2 x 0.75") = 7.5" net tire tread, since there are two sides on the tire, outside and inside. I can imagine commenters leaping to tell you that you are wrong.
Hey Uncle Tony , do you think some time you can explain how to adjust push button 904 trans cables at the transmission? Thanks you are a wealth of knowledge. /6
Being a street/strip hot rodder I understand parasitic loss very well. My question is when you go to the stock rims why wouldn't you use 10x29.5s? They are the industry standard small tire and you'd gain traction and exchange parasitic loss.
It's good to hear someone that knows their shit 👊
Thanks Tony
Old school motor head that's for sure
Eh... idk about that...

Outstanding video as usual. Uncle Tony doesn't fuck around!!
Another awesome UTG video explaining tire pressures and wheels
Taller tire more footprint front to back, never thought of it that way but your right. I learned something again Uncle Tony.
Great tire pressure tip!!! Cant wait to see it run!!
Steel wheel better in traction limited situation? My MIND IS BLOWN. I never even considered it before. Damn.
What would a guy who got a stock 5.0 mustang to go 13.50’s on stock gatorbacks know about traction? 😂great video as always uncle tony.

Perfect video for me now I'm really diving into my frost real street strip car
I have a set of those 15x7 cop rims they are a great looking rim and look good when you put a wider tire
Good analogy, 1 revolution was 7 feet lost. Very true
