Is this another long pennzoil commercial or is it watchable?
Wise man once told me, “no admin runs” meaning please where at least some eye pro! (Especially with exposed driveshaft) Gotta keep the videos coming bro😂😂 hahaha glad you’re good

Hey rob, lock washers don't actually lock. Aerospace tries to not use them because they suck. Lock nuts, lock inserts, or a lock liquid are all more preferable than a split-ring lock washer.

Google "NASA lock washer study". Really. NASA did a study in 1990. Lock washers are not effective. Keep up the good work and pushing the enveloppe.

Safety equipment at work! Agree on adding the second loop to protect the passenger. Glad you weren't injured even without anything covering the tunnel.

So glad you're okay Rob, probably time to cover up the drive shafts before you're killed, or lose an arm?

@1.21 do you see the face of your friend standing behind you Rob...........that face realises exactly how close you just came buddy! Common sense and basic THOUGHT should be telling you NO MORE DRIVING THE CAR UNTIL THE TUNNEL IS COMPLETE...........or carry on risking life man!? P.S........rings around the shafts will not stop shrapnel Rob!!! Wise up man ffs eh! To Rob's family......get his head out his ass before he KILLS himself.....literal stupidity like I have never EVER witnessed before! 2k horses and exposed shafts......STUPIDITY! Sorry Rob, I love what you do man but being a lifelong engineer I gotta call it......finish the tunnel ok, you know and I know you know you daftarse. Take care about your life, people will miss you!

This is all part of the learning curve. Understandable to be upset about it but the test runs served their proper purpose. 🧠👍🏾

Just a quick recap, rotary's don't make torque like a piston engine, glad to see your fine, hopefully next time you test your launches you will be smart enough to put a floor in or some kind of protection

www.mazdaforum.com/forum/mazda-rx-7-33/joe-maddox-super-rare-1-100-1989-fc3s-gtus-rx7-2jz-gte-vvti-build-43602/ I have found and saved the rarest Mazda FC RX7 ever made! Now this car is rare. Really rare! Let me break this down really quick... Ever heard of the rare 100 GTUs rx7s? Only 40 have ever been claimed and only 11 are confirmed at the time of this posting! Here are the rarest rx7 FC3S models: 1500 10AE Turbo models 1400 infini 1000 winning limited 150 final edition convertible 100 GTUs... out of that 100: 83 red on black 10 black on black 7 white on blue There was only 100 GTUs models created between 1989 and 1991. If you own one of these rare models sign your car up to the registry list here on any of the rotary forums! There are rumors about a restamped GTUs model... The entire origins GTUs owners thread on the rx7club was modified, icemarks claims deleted, registry list changed to have a confirmed section and the mods agree there are not enough GTUs models to have the restamped. If you want the full story behind the restamped models: www.mazdaforum.com/forum/mazda-rx-7-33/restamped-mazda-rx7-45926/ www.rx7club.com/2nd-generation-non-technical-pictures-198/restamped-mazda-rx7-1148475/ If you have a real GTUs you can register it here: www.mazdaforum.com/forum/mazda-rx-7-33/official-mazda-rx7-gtus-owners-club-thread-44477/ www.rx7club.com/2nd-generation-specific-1986-1992-17/mazda-rx7-gtus-1148362/

Helical spring lock washers are complete trash and do absolulty nothing. There is a reason why nasa doesn't use them. If you wanted something that works nordlock is the only way to go.

You could change the transfer case to a V35 electronic style transfer case to eliminate the hydraulic system. Although not sure if it will handle the torque and power.

LOCK WASHERS DO NOT WORK! . proper torque and blue (or in this case, red) lock-tight is the only way to make sure stuff isnt going to back out. . im 26 years old.... mechanic all my life.....dad was a mechanic all his life lock washers work in SOME cases but lock tight, lock tight, lock tight...... . the crap works

Please cover the transmission tunnel before driving the car. You’re lucky you weren’t seriously injured.

I've got $100 that says Rob will now put shielding over the transmission before testing out again. Hopefully he's taken some time to think about how bad it could've been if gears in the trans exploded through the side of the housing instead of the sheering off the driveshaft mounts. We're glad you're okay Dahm, but bro, you're going to need to put something between you and that trans.

Hate to say it, but if there was a drivetrain failure and the trans seized, that yoke broke due to the momentum of the car and the grip of the tires. Not broken from engine torque.

Rob Dahm: This is for everybody who says rotaries don't have torque. Also Rob Dahm: There was never a moment past the launch where I actually felt like an insane amount of torque. All jokes aside, boy I am happy you didn't get hurt. Definitely got lucky there, in more than one way! Does this accelerate the plans for a shield to make sure your car will never be able to blow chunks on you again?
