What are the top 10 myths....the one's that sucked us all in at one time or another..

4 of the top of my head are:

1) Grade 5 are a better choice than grade 8 as they will bend where an 8 will break

2) DOM is seamless

3) hollow is stronger than solid, size for size

4) removing a thermostat can cause overheating because the coolant mooves too fast to absorb enough heat.

What are your (least) favourites?

Axle shafts with a "neck down" after the splines are weaker than those without...oh sh!t I didn't mean that..I take it back.

# 4 ISNT A MYTH.....IT HAPPENED TO MY CAMARO ...HAS A GRIFFEN RADIATOR AND A HIGH FLOW PUMP...

ALSO SOLID IS NOT STRONGER THAN HOLLOW DEPENDING ON THE APPLICATION.......

HAHAHa yep #4 is not a myth <IMG SRC="smilies/wink.gif" border="0"> theres a reason race cars use restrictor plates <IMG SRC="smilies/wink.gif" border="0">

Every one is correct #4 is no myth,

If a black water hose sits in the sun with the water going through it slow it will come out warm, It picked up the heat.

If that same hose has a high water flow rate the water will come out with very little temp rise, it did not pick up very much heat.

Careful there, you need to look at more than just the temperature. It takes a LOT more energy to raise the temperature of the oceans 0.01 degree than it takes to turn a cup of ice water to steam. By increasing the velocity of the water you increase the volume of water that was in the hose for the same period of time. Thermal transfer (if I recall correctly) is not dependant on the velocity of the fluid. The heat transfer per unit area is the same no matter how fast the water is moving. The change in temperature you're referring to is a fixed amount of energy over a fixed amount of time, but with two different volumes. If you saw a decrease in efficiency by removing the thermostat then my guess is cavitation reduced your effective contact area.

#6 myth is sugar in a gas tank will carmalize and seize an engine.Sugar does not dissolve in gas.Take a sugar cube and stick it in a glass of gas then stir.Nothing will happen.The only thing it will do is plug filters but you could do that with sand just as well.

Who started that "hollow is stronger" one anyhow? I'm curious to hear the "logic" behind it.

Hammer started that topic a loooooong time ago, it's all his fault <IMG SRC="smilies/thefinger.gif" border="0"> He was snapping d-shafts at the time. Actually he just asked a question and the rest of us ran with it (mostly me I guess <IMG SRC="smilies/rolleyes.gif" border="0"> ). You still out there Hammer? Haven't seen you on here in a while. <IMG SRC="smilies/beer.gif" border="0">

10) Everyone will agree that a common belief is a myth, if only you use impeccable logic in explaining the falacy.

letts seeeeeee ahhhhh

You are correct the formula is btu per hour= temp difference X gallons per minute/24.
But when taken to the extreme all betts are off. A true life example is, a airconditioner with too much air flow across the evap will ice the coil because the air is going too fast to transfer the heat. Slow the fan down and the coil will not ice up. If you slow the air too much the ame thing will happen not enough heat transfer and the coil will ice up.
The same goes for water chillers which is just the oppisite of a radaitor, too much flow and you trip the freeze stat or too low of water flow and it also trips.

Cavitation is actually caused by reduced suction pressure.
I pulle dout my old Start Test And Ballence book.
" Cavitation is the result of insufficient avaible net positive suction head, causing low pressures such that some of the pumped liqued flashes into vapor and form bubbles. These bubbles are carried with the liqued as it goes through the pump untill they reash a region of higher pressure within the pump. Within this region, the bubbles collapse with a severe shock on the adjacent surface. This is called cavitation and is accompanied by noises including crackeling and sharp ratteling noises"

Got to have shackle reversal in the "myth" catagory. <IMG SRC="smilies/biggrin.gif" border="0">

As well as the Mopar MPI being a "good" conversion for the 258.

Enough said about DOM. <IMG SRC="smilies/biggrin.gif" border="0">

if you add bigger tires and a lift you will ruin your transmission and your axels. <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/rolleyes.gif" border="0"> <IMG SRC="smilies/rolleyes.gif" border="0"> <IMG SRC="smilies/puke.gif" border="0">

stupid try guy, they work better now!

but the gas mileage sucks, but the tires make up for it in the fun factor! <IMG SRC="smilies/biggrin.gif" border="0">
