The cleanliness of your shop amazes me every video I watch...Thanks for taking the time to pass on your incredible knowledge. I love your no short cuts attitude.
I hate a chassis that has no head room or your sitting on the ground. The most important series of videos you can watch when building your car here ! Listen to this man and plan ahead.
I enjoy your posts. You take the time to say how to accomplish your task but you go the extra mile to explain why you need to do things the way you teach. Great job.
Had a crash in August rolled twelve times. Maybe more I flipped into the woods. I was driving a car I hadn't been in and had so much room. Im 6'2''. It was a 55 chevy and I had at least 10'' above my head to top of cage. During the run I went into severe tire shake and got out then back in it [ dumb] But that's no prep racing. Car was going straight till the rear broke in the 3rd member sending me into a 180 before I even knew what happened I was in the guardrail rolling . The amount of g force I felt before the lights went out. I broke a brand new pyrotec carbon fiber helmet. It was cracked in 5 places o the crown of helmet. Before I made the pass I pulled the belts as tight as humanly possible. Somehow during the roll my head hit the top of cage knocking me out for 8 hours. My head was 10'' away from top of cage. I can honestly say without a doubt if I was in my camaro where my head is nearly against the roof id be dead. My entire outlook on the seat and cockpit has changed. Take it very seriously. Beef up the seat mounts as well . The seat mounts broke under my ass but not at my shoulders. It was a moly car built by a great builder not you but a common one . The car saved my life and I thank god every day. My suggestion is padding and containment. No carbon fiber seats at all. Ive been researching Nascar style seats and how they keep the driver contained . I was fortunate hope my crash and this little write up helps and paints a picture.
Part of the reason Nascar is using the custom molded carbon Kevlar seats that cost $20,000 is for impact absorption from other cars. Before they went to those most drivers used The Joie of Seating. They make, in my opinion, the absolute nicest full containment aluminum seats on the market.
I've loved drag racing since I can remember. I know I'll never build a car like this but I LOVE to learn!! Thank You!!
For someone like myself doing a ground up build these vids are greatly appreciated. Thanks Tim
Tim this video is one of the best on safety I've ever seen thank you sir.
As grumpy as you seem to be there is a damn good reason for it. You really care about what you put into the cars you build and you want to keep people safe. You are 100% the type of guy I'd set down with and drink some Bourbon and have a chat. 10lbs of shit crammed into a 5lb bag. I about fell out my chair and spilled my drink.
Tim, you are a gold mine of race car knowledge, i would rather be safe and comfortable and walk away from a wreck than not.
Always a pleasure learning from you. Thanks for your time
This is so important and true.
I'm 5' 11 with short legs and my head would rub the top of my friends ChevyCavalier and I could stick the top of my head out of a Chevy HHR with the sun roof open yet I'm certainly not a tall person.
Thank Heaven today's cars have higher roof lines.
I laughed my ass off when he said ‘10 pounds of shit in a 5 pound bag’
Love how this fella doesn't bullshit about safety or language or even how he doesn't like his own product. Good shit. Everyone likes a good shit.
Great video as always! Thank you!
My word, I have never seen a DoAll saw that big. I've only had the experience of using one when I was in the MD. ANG and it was half the size. Those are fabulous metal cutting saws. Great video.
Grandpa Tim, always throwing the wisdom out there.
Great info. I pray everyone takes care to make the drivers compartment right and safe and not just able to get thru tech.
do me a favor and mention for the guys that are doing the work for themselves that the steering should be done before the headers, etc., don't build the headers then fit in the steering. I have had RACE cars come to my shop with 5 u-joints in the steering shaft, never mind the street cars. Never mind that the steering geometry is all wrong, and that the parts were made either for an Abrams Tank or a sewing machine. Thanks for all the help. Great job.
I look forward to your videos.
I can't like this enough! It's the little things that will save your life.
thanks again Tim, another great video... My concern about head room, is even when the rules dictate a minimum distance form the top of the helmet to the cage above the helmet, it's still not large enough (of a gap). No matter how tight one gets their belts, they still stretch a surprisingly large amount. Compounding that is the amount of layers of clothing the driver is wearing. Then there's the slack in the belts themselves (again, no matter how tight you make them they're never tight enough), then there's the belt webbing itself stretching (once the slack is taken up). So something like several inches from the top of the driver's helmet to the (bottom) of the top of the cage, is going to be used up rather quickly, and that helmet will stop when it hits the bars or steel strips, but the body is going to still keep moving upward (or I should say outward) from the roll, compressing their spine.
I know you know this of course, but I guess what I'm trying to say, is that especially with lower roof lines like on ProMods and the like, it's just not enough space to allow for any kind of movement, even if one follows the rules or even adds a little more. I think safety in this concern is still very limited. Something needs to be different, a way to keep the driver from relying only on the belts to keep them from being pulled up/outward in a roll. I think we're asking too much of the belts, it's one thing to rely on them to keep the driver in the seat, but it's not going to keep the driver from being stretched and deformed in high G wrecks. I think a better idea, is something maybe akin to the way you'd see how people are held in on some amusement park rides, where the rides go inverted. Instead of belts, it uses a structure that comes down onto the shoulders of the passengers, keeping their body from being thrown out of their seats. Because it's a rigid structure, it has much less chance of moving (deforming/stretching) than belts have (if at all). I'm waiting for a team to build a swing-down rigid padded shoulder restraint like that for a race car, I think it would be a huge improvement and you wouldn't be have as much of a problem with head room. The belts would still be used to keep a driver's general body in place, but the shoulder restraint would prevent any further movement upward/outward in a roll (and it would be on a hinge so emergency egress wouldn't be an issue).
Just a thought... I might be missing something, or two, but just wondering what you think... and don't worry, I have thick skin
Oh and I spent the night in a Holiday Inn Express.... once.
great video Tim and all said is spot on.
A more comfortable rider or driver will go faster than the same care where they are not.
when i was doing these things we build the car then make the owner /driver comfortable and fit correctly.
you cant do that you ain't done it right.
Tim thanks for the info. You say it like it is. And offer to help people. Shit you rock brother.
Thanks Tim..🏁🏁👍
you have a way of cutting through the bull shit and calling it what it is.....You are saving lives!
A buddy of mine had an 8 second Mercury Comet manual trans car with pedals hung on the inside of the crossmember. He was 6'3" and I have no idea how he folded in behind them.
Whats your option on kirkey seats?
Lol at that picture of Shaun!
It's ridiculous how many people you see in the most effed up positions in their cars. You'll also see drivers that have some of the best safety equipment and the most of it you can buy but are jammed in the car where it's not going to make a damn bit of difference. I really like that you go the extra mile and explaining why people should do this, you don't know till you know but there are people that know better...and hopefully they make changes before they become confined to a chair OUTSIDE of a race car.
You sir are Captain Sensible.
Can you make a video comparing the momo to the racetech?
Absolutely correct you just don’t get a RE-DO or a TIME OUT WHEN YOUR BARREL ROLING DOWN THE TRACK!
Should the drivers head be tucked in the funny car hoop area ?? Some cars I see people’s shoulders even with the cage and they are not tucked back in the hoop
The car can be replaced, the office must be the best you can make it.
I swear to god Tim is fucking hilarious!
✝️🇺🇸👍 thanks for the info. And for your concern for safety and the sport
39th👍's up Tim thanks for taking the time for us all
I prefer these videos unedited - like at 1:48 - we know some classic material was left on the cutting room floor right there.
👍👍👍👍👍👍
I don't half ass anything I whole ass it. 🤣 I jokes aside great information
Love the attention to detail. I wonder what Tim would do if he had the chance to build a helicopter...
why not position the driver more like a single seater with a more reclined position
reclined seating position, that would work well in say a road racing setup, is just not the position you want to be in for drag racing... you want more of an upright position
2:25 Cars are getting smaller, but Drivers are getting bigger.
Are you calling me fat?
lol
I’m not fat, I’m under tall.
it's scary how sketchy how some of the pro cars are seat wise. Fuel cars with bullshit headrest foam. Stay safe.
Personally I blame squirrels
let's pretend for a moment that this video is not about race cars, but instead is about the health and wellbeing of a nation, or even a planet.
How do you deal with all the obese people Tim? Gota be hard to fit, and balance out a chassis, with a 350 lbs blobber...
get too the point
Racing is supposed to be dangerous and life threatening. If it isn't dangerous, it isn't racing.
and that there folks is the most classic, ignorant statement about racing
