Add to this list of Hard-to die-Fallacies
 

Some practices/believes that don't seem to die out:

"The car has to come to a full stop before the Odometer can be re-set"

"Disconnect the battery with the engine running to test the alternator"

"Test the CDI by checking for Voltage on the coil with a test light"

If you know of any other ones, post them here. SmileWavy

You have to lower the compression ratio to turbocharge an engine.

If you shave your chest the hair will grow back thicker.

The early 911S isn't good for street driving because it's cams are too peaky.

Turbo tie rods make a BIG difference.
Muhahahaha!

The same is true for your...wait is this supposed to be about 911s? crap this is okward... :rolleyes:

A well set up 915 is just as good as a G50. :D

I'll save money by buying a 911 that needs some work and then doing it myself.

this from the guy who just had to rebuild his odometer :rolleyes:

Placing the motor behind the rear axle makes sense.

These cars oversteer!

CIS is a cheap & easy FI system to maintain!!!

CIS is easier to maintain than MFI!

<i><b>... this from guys who have spent thousand$$$ on alphabet-soup CIS parts to repair their systems using the 'Shotgun' method of troubleshooting!</b></i>

Ha - Warren stole my thunder... I'll add one tho:

"CIS is a good system for a sports car"

Said to an admiring crowd "I'll just lean in the window and start her up"...

Trickle-down theory.

"Galvanized tubs don't rust...."

"The only way to get CIS to work properly is by spending a lot of money and swapping in a lot of new parts in a shotgun approach to solving problems!"

Oooh-oooh I have a few

G50's weigh 100lbs more than a 915

930's have too much lag

Why are Porsche parts so much more than a Small block Chevy

:rolleyes:

"I'll save some weight by putting on RS door panels"

carbon fiber cup holders... I can go on...

Carburetors work better than CIS.
CIS is expensive and complicated for everyone, not just for those who don't understand it and try to fix it with the shotgun approach (replace everything until the problem goes away instead of doing a logical systematic diagnosis).
SSIs will get you 20 hp throughout the powerband.
Loud exhaust is better.
$100 per hp increase is a reasonable price to pay.
The big bad oil companies are conspiring to rip us off.
Changing from CIS to EFI is easy and fast.
911s should be drag raced.
Wings on the street are cool.
Installing carrera pressure fed tensioners is actually an upgrade.
dodging cones at 30 mph in a parking lot is really racing. ;)

One certainly can reset the odometer while the car is moving. I've done it several times. I've also repaired several odometers, and yes, there is a connection.

I have rebuilt 2 odometers. On both the gear was like crumbly brown sugar. It would not have made any difference if the car was moving or not when they fell apart.
I also studied the internals really close to determine why this rule would apply. Yes, I'm an engineering geek.
I figured the odometer gears were somehow locked during the transition period or were meshed with other gears periodically and that would not allow the odo to be reset.
Nope. I found nothing in the design that would support the claim that re-setting them when the car is moving will put more stress on the gears than if the car was stopped.
Maybe I missed something?

and deleting the arm rests, speakers, door bins, and panel caps. (I never made the statement - but the last time my doors were diassembled - the combined weight of that stuff had to weigh between 5-7lbs). Now to someone who drills out hinges - that could be the equivalent of 5 tons. (but I don't do that either. I better get to it ;)

My contribution....
The long winding road is too wastful of gas to take....instead...drive the straight and smooth road at 55 MPH.

"Make sure you put your battery on a piece of wood and not just the concrete or they will discharge"
"Someday you will be able to get out of that old 911S and move up to a new Porsche, like this Boxster"

'74-'77 were the worst years for the 911. :rolleyes:

You can do a 3.6 transplant for $8,000. (OK, $10,000 TOPS!)

You have to remove all rust before using POR15.

"You can drag race a 911 and not break things, just launch easy".

My favorite:

"If I paint it black instead of white it will absorb more heat radiation."

"Wider tires have more grip"

" Targa seals will never leak."
" Turbo tie-rods take 3 seconds off a lap."

Taking undercoating off is easy.

"Porsche engineered a high-performance engine with a low-performance air filter"

Porsche is a two syllable word.

Ahh... why is resetting an odo on-the-move a "fallicy"...the car is moving and you're "stopping" a delicate gear for a moment....

Sure...it can be done...but it does ultimately lead to faiure...no ?

Swepco gear lube and 93 octane are money well spent.

The factory Klein tool is the best for replacing spark plugs.

Replace the 02 sensor every 15,000 miles.

29 front and 36 rear is the best combination for performance and a smooth ride.

This car is not a mid-life crisis.

Wastegate chirps and spews fire.

KKK turbochargers are best for Porsche engines.

Cross-drilling of rotors is done to improve cooling.

Porsche rotors have cast holes, other brands have drilled, which makes them more crack-prone compared to Porsche pieces.

Good stuff! More.............more. How about spoilers?
Spoilers make the car more stable in rush-hour traffic????
Those Tee-trays, and airplane wings, I see on cars that rarely get driven past 80 miles/h??:rolleyes:
(I don't mean turbo wings, or RS-humps, which have been tested in a wind tunnel for high speed)

I see that there are still disbelievers on the odometer-reset-issue.
Not only have I looked at the VDO mechanism myself, a subsequent contact with North Hollywood Speedo confirmed that there is absolutely no danger in resetting while the car is moving. The same message came from Palo Alto.

Still doubtful? :p Ts…. Ts… ts…..Find out yourself from the experts:
