Conrad is awesome.
The Corvette is super awesome.
Tophat cam is a great idea for passively filming while working.
Was someone knitting at nationals?

You guys should come to the Eastern Nationals this year here outside DC. Most of the nationals winners (and many highly competitive guys who don't go to nationals) will be there. And it's a lot closer drive for GRM!

Needs a flip-down monocle for a viewfinder.

Great video, note that there's music with NSFW lyrics though.

Reminds me of a request- is there any way that you can talk one of your pros to bring the car that they just ran at the SoloII nationals to take a series of runs? That way, there's a real benchmark to compare to.

The drag race is pretty easy- for the most part- a 1/4 mi is a 1/4 mi. But figuring out where challenge cars sit in the autocross realm is more difficult.

Back when I challenged, I had a personal benchmark in my real autocross car. But that only worked for me.

Great video. Wish they had filmed the drag race and concours parts of the event. Maybe this year.

Amazing video. Is there a build thread for the Justang hiding somewhere?

Unnecessary and inappropriate video music is a plague of our times. Just say no people.

Nice to see video coverage of the event.

Barring serious mechanical issues with my challenge car, I intend to take copious pictures and video this year.

Remember that time we raced our LeMons Miata with Spec Miatas?

We took our LeMons Miata to Sebring International Raceway to join in a NASA event. Being the only car in our Performance Touring class, we were bumped to the tail of the Spec Miata field for the race. No, we didn’t finish specially well… Okay so we finished ahead of one other car in the Spec Miata field. But no amount of body roll and faster competitors is going to stop us from having fun.

Watched this same exact video when I bought the Torsen swap for my C/SP '90 Miata. Pretty cool tech, although they take a little getting used

I've been looking at videos for stuff on a truck I'm looking to get soon and came across this differential video I think is pretty good:

Differential locker comparison

Love the torsen in my FR-S, probably will go with a Torsen in the truck as well. The mechanical selectable OX Locker is something I would like for offroad capability, but its either an open or a locked spool...and I'm not looking to do crazy offroad stuff in a 2WD truck, just some prerunner capable handling when in Arizona/Utah unpaved roads/deserts.

Good explanation. It took me three watchings to wrap my head around how it works with a wheel-speed differential (as when cornering), but I finally got it. I kept wondering how it doesn't just lock in that situation, but I eventually got the point about equal but opposite speed change (+20% and -20% in the example). Ingenious. I do wish it would have talked about what happens when one wheel lifts. I'm still not clear on why a Torsen would go "open" in that situation.

In reply to CLH:

That's a good question. I wonder if for some low level of load, the spur gear can drive the worm gear. I imagine it comes down to the angles involved.

But even if I grasp it a bit better now, I wouldn't say I have a solid, intuitive sense of the action. I wouldn't be at all surprised to find out that guess is in left field.

How so? I'm sure the Internet can tell me some stuff about how they drive differently to a clutch type LSD, but as long as you're mentioning it...

"You can't backdrive a worm gear."

There ya be.

Torsens are nothing more than using worm gears for the side gears in an open diff. An axle can easily overdrive the diff if there is differential speed, so it still has all the benefits of an open bevel diff.

The 2017 Tire Rack Ultimate Track Car Challenge is coming up in May. What better way to get pumped than listening to mighty loud turbo noises from Element Tuning’s Scion FRS from the 2015 UTCC?

This guy doesn’t need one. Driving a shifter kart slowly in the rain can be challenging for most of us. Then there’s this guy.

Looks like Nationals this year. I think JA/JB ran in the rain on West Course when it started, and KM ran in the rain on East Course as it was drying. Both looked more like boating than karting.
