I did that as well. It hurt. So yes, everybody take note. Watch out for the manhole in European Straight.

Is this the setting that was the best back when the surface was in better shape, or did you have it set firmer back then?

Were the old Goodyears a firmer tire by nature, or had they gotten hard with age... or both?

Did you play around with tire pressures much back in the day? What pressures ended up being the best for you? What pressures work best with the new tires?

Hope you don't mind the questions. ;)

That thing needs a coat of white spray paint applied at 3 A.M. sometime soon, huh? :D

Some guy in a orange safety vest has been up their with hi-vis marking paint. He "appears" to be with street maintenance. I'm sure that offending manhole will be highlighted soon. ;)

Woo hoo!




Wait... dude... what about the vest???? L O L !

Gah... not much room between the edge of the "berm" around the cover and that pylon.

Betcha can't blow through there above 80 and not suck the pylon out of it's spot.



Whoever took that needs to work on their pan shot. :D

Tire settings
 

The settings remain the same. The road surface condition has always been in question.

The Goodyear Racing Tires are a reletively stiff tire and it gets worse the lower profile you are running, ie:shorter sidewall equals harder ride.

The old Goodyear Racing Tires were beyond hard.
Tires made for 6 hours on the track, lasted for 32 years, and they had turned into bakelite.

After experimenting with tire pressures back in 1976 when the car was new, some baselines were establised.
Front tire pressures below 28 pounds made the car slow-responsive. Above 32 pounds and the ride begins to feel harsher. It is a subtle difference but one you can feel.
Rear tire pressures below 30 pounds made the car feel not-tight, like the rear end was swagging around in the turns. Above 34 pounds and the ride is significantly harder.

Racing Tires are porous and as a result before EVERY run the tires are checked for accurate pressure.
They are set to 30/32 in cold weather (winter) and 28/30 in hot weather (summer).

Note that stiff shock settings are not always the hot ticket. Moderation is good.
Installing RSR Torsion Bars made a big difference in stiffening the ride and soaking up the bumps. Also larger torsion bars make the car handle flatter
The faster you go, small bumps become bigger ones due to the car's increased velocity, F=ma.
Stock torsion bars cannot handle the bumps at speed due to their softness (for a comforatable ride) and can cause large unpredictable bounces resulting in losing control of the vehicle.


Suspension specs are available also if you are interested, all reciepts are saved.

Great stuff. I'd love to know the size of the RSR torsion bars f/r and the anti-sway bars f/r and, finally, the all-up, ready to roll, weight of the car.

One of the local slalom clubs that ran at Jungleland was El Conejo. This was related to me by a friend named Lenny who was a member. He raced a blue and orange BRE flared 510 and worked the parts counter at Miller Imports and later Woodland Hills Datsun in the Valley. I suspect several of the local sports car clubs also hosted events there over the years. Usually the slalom clubs would take turns hosting events. I'd love to see some pictures from those days.

I wonder if that Lalique eagle was Pontiac's inspiration for the Screaming Chicken?

Suspension specs
 

They are Teflon coated RSR Torsion Bars; 21mm front, 29mm rear.
The Anti-Sway Bars are; 17mm front, 18mm rear.

The car will need to be weighed to get an accurate number. The Scheel Nomex seats are considerably lighter than the leather Recaro Sport Seats and will change the final weight of the car.

Is that the slate gray 930 formerly owned by Steve McQueen that changed hands last year?

Very interesting - quite close to my car, at least suspension-wise. It has hollow 22/29 torsion bars, 22/21 anti-sways with re-valved Bilsteins and 9 & 11 1/2" wide wheels (though 17's). Current weight is right at 2,500# w/o driver and spare tire. Sadly, it has only the stock U.S. 3.2 and none of the chassis stiffening you have done.

As noted above, my recent cruising speed test run on Mulholland was pretty jarring. Maybe it would smooth out at speed, although I am not likely to try given today's traffic and somewhat less lenient police attitudes.

I look forward to seeing your beast in person.


Oh, one last question, if you can stand it - who did the metal work on the chopped top? Given the shape of a 911, that had to be a real SOB to get right.

Hmm. Pretty similar to mine as well: 21/29 torsions with 22/22 sway bars but I'm maxed out with 7/8 in wheels under narrow-body fenders. I'm also about 100HP shy of Chris's engine. :eek: The good news is that my car only weighs 2,150lbs with spare and 1/2 tank of fuel. :D

Your car on 17" wheels and similar torsion bars would have noticeably stiffer effective spring rate than Chris's car (or mine) so it's no surprise that you found Mul to be a bit rough.

Slant roof
 

Thanks Bob!
Your car sounds real nice. I look forward to seeing it.
Arnie Verbieson and and an expert body man named Don did the incredibly good job of slanting the roof. It was done at Arnie's shop on Ventura Blvd.
See you on Mul. ;)
Soon

just curious, how did you/they get the glass to fit? or did they have to get custom glass all around?

i've actually been wondering about this ever since i first saw the car, and just now remembered to ask. :)

It's a laid back windshield. Not really "chopped". So the stock glass fits.
