Just for fun...

Cool! Are those M and S gears?

Hi McMark, is that axle scratching at the exhaust pipe? just wondering!

Yeah, the axle just kisses the lower exhaust mount bolt. I just need a shorter bolt.

cool, now you need to wipe all the oil mist of the camera....

Way cool Mark, I need to make up to your place a shoot a cool vid of you and that car some time.

Whoever held that camera did a great job.

That's very cool indeed!!

When my shop-car is finished and on the road, I want to shoot with 2 or more cameras and edit it so you have a suspension-cam in a smaller window on the screen as you see a fwd view.

I love the mechanical-ness if that angle. Next time mount it on the other side so we can see the gear changes too!!

Two things:
1: Cool Video, way cool actually
2: Mark, you really have too much free time on your hands

HA! Made the GoPro mount in about 2min and shot the video on the way to lunch. In my 'free time' I laid up two large fiberglass pieces for an oil cooler shroud, powder coated some trailing arms, bodyworked the third piece of the oil cooler shroud, installed an amplifier, quoted a 911 engine rebuild, a Type 4 rebuild and a BMW E36 engine rebuild and helped Jeff S. with his six conversion.

Was that detonation "run on" at the end?

Very cool. Wish I had that kind of "free time".

Starbucks

Coffee - Yes. Napa has a great local roasting shop.
Starbucks - Never. My employee used to get me his favorite drink. Some triple shot whatever. It had a distinct flavor of crap. No thanks.

And you know this, how?

To elaborate: It had a distinct flavor that reminded me of the smell of crap.

I was noticing the trans mount flex during shifts/acceleration in the early part of the video. Then the camera position changed. Does that appear to be a standard 914 mount and would the solid 911 mount be more rigid?

Thanks for the video. That was interesting.

enjoyable vid

I nominate this car, as car of the year, 2013

also, it looks like mark got himself some HEAT

Had no idea the suspension moved so much. Also loved the tin knocking sound at the very end. Things falling off?
Thirdly this is a great diagnostic tool looks like. Movies of moving parts.

Cool video Mark. Was waiting for the 6K hit....

Take 2?

Never seen how the suspension works. It'd be fun watching a big pair of slicks under corner load.

Well Napa has a lot of tasty products. Which makes me wonder why the hell are you working so hard?

The GoPro was mounted on a strong magnet. Mine came from a dial indicator setup. The base portion has a M8x1.25 thread. So I welded a small bolt to the bottom of a plate and threaded that in place. Then used one of the GoPro stick on mounts. I also drilled the plate for a backup safety wire so I wouldn't see the GoPro bouncing into the gutter out the rearview mirror.

For this video I just stuck the magnet to my muffler, and under acceleration it just shifted backwards until it hit the raised edge.


The 911 mounts are supposed to be more rigid. I might have to do some testing. >:)


Exhaust cooling contractions. The catalytic converter on your newer car makes the same noise as it cools off. I've never heard my 914 do that until this video, so it's rather quiet, except on the video.


Definitely Randal. This opens up a lot of fun options. Rob (ConeDodger) and I just bought a chassis to build a race car and after this I can see welding in camera mounts in various locations for diagnostic and research purposed.

your internal gopro settings should let you set your video capture at 1080p.

should be slightly better resolution vs 720p

jim

Hmmm... The original is 1080 on my computer. Maybe something about rotating the video.

XD1080's look to work nice:

That was my first reaction too. VERY cool!

seems like my computer has recently begun to limit youtube res at 720p. odd?

seems like a known problem, I see.

Made another one. The body sheet metal isn't thick enough to support the weight of the camera. It ended up testing the safety strap.

Randal this one includes a 1st-3rd 6000 RPM run. It also includes twisty mountain corners, you just can't see them because the camera is flopping around.

This is why the bushing replacements like McMark's needle bushings and the Elephant Bushings make such a dramatic difference. When there is no stiction in the suspension the trailing arms and A arms move freely allowing good shocks to do a good job. This allows you to go much stiffer with the torsion bars and rear springs without feeling like you're riding on rails.

This is a really good diagnostic tool Mark. Between your GoPro and my two GoPro's we should be able to shoot some footage...

Both videos are way cool, but that last one rocked! Loved the free-flying GoPro, hanging on by a prayer and a safety strap!

I liked it, too.

you should make a bracket that bolts onto the muffler hanger bracket...something you can leave in place and bolt down the camera...

Seems like some sort of isolation dampening would filter the audio a bit too. When hanging in free-space, you weren't picking up so much transmitted vibration.


... and now I know how a set of dingle-balls sees life hanging from a hitch receiver

Very cool. A new diagnostic tool. I kept watching that white wire to see how much it would move in the slipstream. Not much air flow right there. I don't know how fast you were going. I was thinking of airflow for an oil cooler.

I probably hit around 70 at the end of my hard acceleration. I would have looked, but my speedo cable broke last week. Can't these old cars ever stop fighting back.

Yes, attaching strands of yarn or string all around the underside to show the airflow under different conditions would be very useful.

Oooh! Good idea!

Needle bearing mounting for the trailing arms does make a big difference. I was surprised but you can feel it right away and the handling was substantially improved.

Great video Mark. Never thought about it, but I have the perfect platform for taking a video, i.e., no trunk floor.

Are the cup washers missing from the top of the tranny ears ???
Damn cool way to see what's going on down under !!! This is a great use of a Go Pro !!!

Jack

Very cool, both runs!
