I agree, Chris. But it's not for my shop. Painting tools to match the walls is taking garage organizing too far, without a doubt.

Although, I have to admit, my lift does match the cabinets. :rolleyes:

Jack,

"I hope the support struts are stiff enough to resist the down force generated at speed. I wonder if some wire cross-bracing would help the struts twist resistance?" (post #1937)

When I typed that thought, I was trying to imagine the dynamic airflow deltas presented in the turns. Looking at your history charts, I could not see the change in performance stats versus the physical position on the track, but you say your foil's drag really penalizes you on the straights. I'm wondering now if a different foil profile would possibly give you a better trade-off between drag and lift to make the most of what power you have available before you hit the rev limiter. You'd be trading less drag in the long straights for somewhat less down force in the (relatively) shorter turns.

It's a delicate dance you are doing on the track; trying to squeeze the most overall performance out of that lovely machine. I guess I'm proposing the different foil profile might provide a bigger benefit in the straights (less drag = higher speed = quicker time) than the penalty of less down force costs you in the turns (time-wise).
:dunno:

We went through dozens of airfoils in choosing this one. The criteria were (in order of importance) lift at lower-than-usually-tested speeds, how gradual the drop-off was right before stall, and drag. This profile was the final wing standing. But if there's a better one out there, I'm all ears. :)

I think drag plays a larger role in airplane thinking because fuel economy is so important. At track speeds, the speed difference between having this wing on and not having it on is not very great -- but I haven't done a lot of testing with it in that respect. If I thought about drag more, I'd probably want better airstream shapes for the uprights and around the fasteners that hold everything together.

But then I'd want to take my rear-view mirrors off, and shave off the rain gutters along the roof, and do something about the windshield gasket and the abrupt roofline change near the top of the windshield. And I'd line the wheel wells. And... well, I think whatever OCD I've got might just take over. :willy_nil

Thanks. Los Angeles has a great climate and my old Porsche is a nice piece of engineering. But our streets ****, our air is polluted, and we are crowded beyond belief in our ridiculously-overpriced neighborhoods. But you've got to deal the hand you've been dealt, I guess.

Is that snowmobile drag racing without snow? :headscrat

I'm trying out a new (less expensive) camera, and I took some pictures of the garage since that's a good point of reference against the old camera. So here are some gratuitous pictures from this afternoon.

Thanks!

And yes, coby65, I've been to Laguna -- although it's been a while.

The last time I was there, I stopped at the intersection where James Dean crashed his Porsche in Cholame, CA.

This is a picture with the aero pieces out of the trunk and on the car -- going down through the corkscrew and getting a little light.

Back in 2002, I was there in the earlier iteration of my car -- and left a mark on the wall just past the exit of turn 9. That was a pretty bad day. The in-car camera caught me breaking my steering wheel and losing a windshield. The car needed a whole new tub after that. (It was also the moment where I decided to invest in a cage, fire system and head and neck restraint.)

There's still a black mark on the wall where I hit it. I sometimes see it in race coverage on that track on TV.

Cool!
Yea I have heard some of the locals talk about that light feeling in the car the first time you drive into that section. They say it takes a few laps to get used to it.
I am getting ready to bring out my 65 mustang fastback from GA and plan to build it to hang some of those curves out at Laguna on occasion.

That shot of the departing windshield must give you a vivid memory of a 'high pucker factor event'! I'd keep that pic on the dash just to remind me to be cautious when pushing the envelope.

Jack, I know the feeling on the safety gear upgrade. I saw a friend of mine nose a car that I had just been driving into a wall at CMP. The throttle stuck at WOT. He was lucky to walk away, but I bought my HANS the next week and haven't driven without it since. The cost of all my safety gear is still cheaper than an ambulance ride and a night or two in the hospital.

Funny thing is, it's not the last windshield I'd lose. I went off of turn 1 at Thunderhill and spun so that I was going backwards (pretty fast). The cabin pressurized enough so there was a 'thop' sound, and the winshield rose up and out -- it pushed the wipers back but never touched the car.

A friend and I had to make a two hour drive to a salvage yard that night to get a replacement windshield. It was the first time I ever got smashed bugs on the inside of my rear window. A friend loaned me a police scuba mask for the drive, and it was very helpful. We got a lot of strange looks when people figured out the car did not have a windshield. But we made it, and got to the next track (Buttonwillow) for more racing the next morning. (It was a seven-tracks-in-seven-days event called the Open Track Challenge.)

And while I'm talking about Thunderhill, I once caught a pheasant there.

Nice pics Jack, but I have to ask: no valve stem cap and rubber valve stems? I would have thought you'd have to run metal screw-in stems with metal caps to pass tech inspection. Just food for thought (and my OCD contribution)!

I think you'll find that they're his "daily driver" wheels & tyres, he carries the race wheels & tyres on a roof rack, shown in an earlier post.;)

A lot of racers use rubber valve stems because they will flex when something rubs against them. Caps should be used as they seal. Centrifugal force can sometimes cause a valve to unseat.

Thanks.

Actually, those are the same wheels and tires I run at the track. I've heard about metal valve stems, but it's never come up in tech-ing my car with any of the sanctioning groups I've run with. I wonder if it's more of a NHRA thing? In any case, I'll look into it -- it seems like a pretty inexpensive step to take, whether or not stem failure is a possibility in road racing.

Actually all you need are these:

I'm surprised you don't have them, but after all this time, maybe you don't need them.

BigAl62, depends on who is sanctioning the rules.

driver, the Fuchs wheels have the stem tucked well inside of harm's way. But I can't agree with you. Contact with anything at speed and the stem is likely to be sheared off.

AFAIK, the NASA CCR doesn't require metal valve stems. I've seen sheared rubber valve stems as the result of WTW contact, but I can't imagine a metal stem would have faired much better.

I use rubber stems, too, and my caps are long gone. Taking hot pressures as soon as possible after getting off track requires it, at least for me.

Jack, that band saw quoted above looks great there!

Gotta stay focussed, Jack... out for a race and ya get a Birdie. And you didn't even have your clubs with you...

Glad to hear you are thinking safety first with your racing.

Take a look at my website, the metal valve stems I carry actually come from the USA!

The last thing I'd worry is something coming into contact with a rubber valve whilst racing as by then even more damage will be happening to the wheels &/or suspension!!:shocking:

'Pheasant under (fiber)glass.' :)

The guy riding in the passenger seat, oddly enough, was an instructor at the Navy's fighter pilot school. I've never seen a more calm reaction to a bird in our path. He told me it was coming and reminded me not to turn -- all in spite of the fact that he was my student that day. We were going somewhere near 100 at the point of impact, and the bird was just pulverized.

It was the very first track day on that paint job, naturally.

And there is also grass drag racing but the coolest is the open water racing. Go too slow and the snowmobile sinks!

NHRA requires steel valve stems for cars 11.99 and quicker, although the rules may have been updated.

I'm sorry about starting the valve stem flap! But I'm good at noticing little things like that! Everybody has to be good at something, I'm a pot stirrer I guess.

Those pilots don't worry about birds in their path - those jet engines are usually designed to withstand one getting sucked through, aren't they? :) (I seem to recall something called "The Chicken Test", or was it "Pheasant" ;))

It's not the bird that goes through the engine thats the biggest problem, it's the one that goes through the radome on a B-52 at altitude and into the cockpit and ends up on the co-pilots feet!

Or the downright strange ones when you have a hole in the wing and find pieces of snake. The bird, some kind of hawk, had been carrying it in his mouth apparently.
