Gear mentioned in this thread:
Earlier in the thread we were talking about the SyFy channel's movies. And silly me, I recorded (and am now watching) the SyFy movie "Mongolian Death Worm". Good grief what a horrible waste of DVR drive space! It simply baffles me that someone got paid to make this turd. In contrast, this morning I watched the classic 1957 Ray Harryhausen film "20 Million Miles to Earth". Both movies contain bad acting, unrealistic monsters and little or no plot. Yet the 1957 movie is a classic example of a late 50's creature feature, and the 2010 SyFy movie is a steaming pile.
I watched "Tasmanian Devils" yesterday....it certainly wasn't the worst SyFy movie I've seen (not that that's saying much).
Back to cars, check out this place I found - it's not far from where I work. It's an excellent idea - and I'll bet they do a heck of a business in Santa Barbara - there is certainly more than enough disposable income there.
Ono was there, yes....

but dead before the first commercial break....lol
(mine has a better paint job...)
Also, what's up with the lowballing? I put some things up for sale, plainly stating that all money is going to a children's rescue home, and I get mobbed with insulting offers. It's for charity, people! Geez.

It's probably precisely because you said it's for charity that you're getting low-ball offers.
You can always do this:
Can you imagine the amount of extra HP this car has just by adding those vents?
P.S. I don't know who that guy on the left is.
We talked about that, and with proper ducting we think we could still put it to use.
Proton, you literally have no idea how many of those types of "mods" are around here. It would be hilarious if it weren't so sad.
Well, I wouldn't even call it a 'mod'....its a joke. I wonder how people take these things seriously.
On a different note, does a hood scoop create issues with aerodynamic drag?
As far as I know, in order to reduce the drag, the air needs to flow smoothly, and the scoop directly connects to the intake. So the engine intake limits the amount of air that can pass through. An imbalance in the input/output would increase the drag??
Hmm... A few questions for the mechanically gifted members.
Today while stuck in rush hour, I noticed my clutch changing dramatically... Out of nowhere, my friction point changed and I almost stalled a few times. The clutch would start grabbing a lot sooner than "normal". Another thing to note is, the pedal was incredibly soft at rest position until you pressed it to about 1/4th. I think I may have a leak or low clutch fluid.
Anyone else's opinion on this?
I don't know how tall the boundary layer is at the center of the hood of a typical car, it depends on whether the flow is laminar (smooth) or turbulent at that point, and whole bunch of other factors. You really only need to consider the part of the scoop that is sticking above the boundary layer. The "NACA duct" you see on many cars is supposed to be the optimal shape for feeding outside air into the interior of the vehicle. You'll notice it doesn't stick-up at all, thus it is entirely within the boundary layer. You still have drag due to the other factors like the viscous drag, pressure drag, etc - but it's the best you can do.
Do you recognize that one? That's on a Veyron.
HOWEVER - all of that is probably just unimportant nonsense, because...
The question is NOT whether the hood scoop increases drag (it does) - the question is whether it is significant. If the drag increase is small compared to the overall drag of the vehicle, then it really doesn't matter - and that's certainly the case with an AC Cobra. Those big rotating tire meats and that open top probably create much more drag than the air scoop - and feeding air efficently to the engine will generate much more horsepower than any impact of the scoop drag.
Gee - that was fun - just like the old days of my former life...
The first thing I would check is the clutch fluid level. If that looked OK, then I would scratch my head and need to call a mechanic!
That's why I'm scratching my head! Might be a leak where I can't see that's causing it to lose pressure and altering the properties of the clutch, or can be completely something else... Ehh..
