I had a guy bust my balls about running something similar back in the day. He felt it wasn't needed and basically said that guys like me were why they kept adding new rules every year. I just said that if a few safety items broke your budget like that ,then yes might want to rethink about racing. What's sad is his son was in a bad wreck later that year at English town caused by the rear yoke breaking taking out the rear brakes, part of the floor and it put him into the wall. The worst part was the tin work cut his leg really bad just missing his artery and he had to be cut from the car. Had there been a real fire I don't think it would've turned out good for him. Funny thing is I fabbed one up for his new rear :-0 But mine were nothing like Tim's artwork and I might even be guilty of making a few of the cages he mentioned lol. But I was young and trying to make a few bucks on the side WHO helping people out back then and while they were a pain to install they did work quite well. Plus it used up a bunch of round bar that I was stuck with.
@@southjerseysound7340 The problem is the rule makers are concerned with making money, not protecting drivers. A rule only comes after a death unfortunately. Same thing in F1, they just recently in the past few years got the "Halo" for protection from the front. And even then it's just on vertical bar in fron with a supporting hoop above the head. Works great for tires and stuff but any small piece of metal that isn't directly in the middle will hit the driver. The IndyCar shield would be much better but there are people who say it shave it because it needs to stay an open cockpit car, most idiotic things I've even heard. Endangering drivers so it can "stay open cockpit".
I love walking into a shop and meeting guys like this... instead of the guy that hits you with all the technical terminology🙄 I can’t learn from that convo but the guy that say don’t fuck with this and screw that shit do this or that’s a bunch of bullshit I can learn from our convo 🤣😂🤣😂👍🏾👍🏾
You should use your technical experience to build a demolition derby car. Maybe you can also explain to us what the heck a T-brace is, and how it's different from a Rollcage (I still don't know).
The last time I broke a driveshaft I had the required front loop. It tore up the steel floor and broke the right side seatbelt mount. Sometimes the rulebook does not go far enough. Thanks Tim
I like running a carbon fiber shaft, they tend to shatter apart when they do break. I dont bj have enough HP for that but it makes me feel good and its light. I still run loops in front and back. I definitely should think about protecting the bottom of the car..
On RU-vid video's of many Late Model Dirt cars, are shown the wild angular rotations of their rear ends ....Looks to me like that shroud is way to tight to clear such gyrations...
It's been said that carbon fiber driveshafts disintegrate with that kind of impact. Is this protection needed with that type of driveshaft? Looks like a carbon fiber Driveshaft in the picture you show.
No need to even watch this because the title lets me know I knew this subject well! Its my wife's muffler that only comes around on my birthday and those rare extremely drunken nights when love is in the air rather than blind hatred for one another and rage! Whew doggy just talking about it makes me excited for January!
Veteran Technician = top notch engineer. News flash experience trumps bullshit degrees. Perfect example of a simple solution with well thought out execution.
Pretty neat little scoop if it ever goes off road. I'd prefer something open to perhaps deter not catching rocks, mud, or gravel, but I'm not a track guy.
These are great rule changes. Make the cars as safe as possible. I personally use a carbon fiber driveshaft because when they break they tend to completely come apart instead of becoming a spinning pole tearing up the car and catching the road causing you to lose control. I dont have near enough power to break a CF shaft apart but its peace of mind and its light
Great common sense idea! Like cheap insurance, that pays for itself the first time it happens. I've seen the mess that can be created, usually high dollar repairs follow it not to mention the time lost.
Your a legend you have a sense of humor but know so much about racing id love to work for someone like you i could learn so much im sure you have forgot more than most will ever know about drag racing
Would have thought that pieces of a universal joint would just rip that to shreds in a single rotation, then the tail shaft could have its way around the rear of the car.
Thank You for ALL of your Info... as I’m building my RaceCar. I’m ALWAYS Looking for the Best Bang for Buck Products Out there, ALTHOUGH there’s no use buying Cheap Ass Products that end up Costing MORE in the Long Run. And you seem to come up with AWESOME 😎 STUFF.
Hello, you may have said it and I somehow missed it, but is that made of titanium? Or stainless? What thickness? BTW, Thank you for doing these videos! This is top shelf information, I dont race a pro mod but so much of this info is directly applicable to my race car.
If your able to get it to be able to follow the driveshaft you should be able to make it lighter by making it even tighter around the driveshaft. Possibly a bearing in a sloted sleeve to go around the shaft to allow up and down sliding while not letting go of the shaft.
That's a very nice design. Very functional but quickly removable to allow for quick maintenance. This is a better, cleaner looking design, compared to that one that looks like a shopping cart wrapped around the driveshaft.
Oh, and what happens when/if the tailshaft breaks in the centre which I have seen c/f , steel, alloy shafts do. And front ones clamped to trans extension housing will usually take that with the explosion.
That's awesome I've had driveshafts twist apart and they make a hell of a mess that's for sure that there is a must have because I know what damage a unleashed broken driveshaft will do
You're better off contacting him. Putting it on a public forum means that A - Its gotta go through 2 separate companies. B - He probably won't see it after a few hundred replies(unless yours has the most likes) C - Its more retail direct. In the same way you wouldn't ask Bruce Springsteen's roady if 'Bruce' has sent your CD out. D - He'll have an idea of who you are and what you're talking about.
IF the tailshaft has a slip yoke it is better to let the tailshaft fall on the track. Though getting out of the gas helps too! Front one is different!!
I've seen them whip with enough force to tear the tunnel out of a car. When they let loose under power it's not humanly possible to get off the throttle fast enough. The other issue that keeps it spinning is other than park or neutral there's nothing to slow it down. Now you don't have to buy Tim's piece, I'm sure he'd like to sell them. But he makes videos like this to keep guys safe and Tim's the type of guy who would rather you be safe even if you have a quality American made loop/cage from somewhere else instead of nothing. I just posted about a guy who was busting my chops saying it isn't needed and later that year a broken yoke nearly killed his son. Thanks choice is yours,but if you're doing anything to the rear it'd be a wise investment. Plus they're easy to fabricate if you want. I used to make them from chro mo round bar for the rears I did back in the day and while not as nice as this,they worked.
How fortunate for the industry to have the wealth of Tim McAmis' experience and designs . Never any short cutting Chinese slap crap bandaid shit from this genius .
