The story that water can flow "too fast" through the radiator never made sense to me.   I suspect that the story refers to changes in the flow characteristics, not specifically to the rate.  It may be that at a certain point flow becomes turbulent instead of laminar, and maybe that is a problem either in the engine or the radiator.  

But all else being equal, you get more flow of heat energy with a bigger temperature difference between the hot and cold sides.  So in general, higher flow rates will result in higher heat transfer to the air.  

The heat transferred per liter of pumped fluid is less at higher flow because the exiting fluid is warmer than the low flow situation.  But you have more liters per minute, so you transfer more heat per minute.  

In most situations, the actual flow through the radiator will be identical for both a standard and high flow thermostat.   It is able to regulate the engine temperature just fine.  But if the stock thermostat is  wide open because engine temperature is above the regulated temperature, then the high flow thermostat will allow a bit better flow and maybe better cooling. 

However, as has been said, originally the cooling system was good enough to keep the engine cool in all situations.  (Possibly not completely true!!).   So, if the cooling ability is no longer good enough, then the problem is not the properly functioning standard thermostat.  It is that the block can't heat the coolant properly, or that the radiator can't cool the fluid properly.

For what it's worth, I have a 1975 TR6 with stock cooling and a
slightly higher compression engine.  I can drive around town in
August, in traffic, in Georgia, and the gauge doesn't rise much higher
than halfway.

(Excuse me a moment while I knock wood...ok, I'm back)

If I had cooling problems on an otherwise stock engine, I'd begin by
connecting a garden hose up to the various cooling openings and seeing
what washes out.

 Hi Listers,
This is a test ... I seem to be having trouble getting TR List Digest emails (last one was on April 13th).
Any ideas on how to resume getting TR Digest from [email-masked]? I haven't changed anything on my side in years! (Using Firefox on iMac OSX and AOLfree)

Old mechanics tale, doesn't actually happen that way.

However, there is another effect not mentioned.  The TR2-6 pressure cap is on the high pressure side of the radiator.  If the flow
rate becomes high enough (or the radiator is clogged enough), the resistance to flow of the radiator will cause the pressure to
rise, potentially high enough to force open the cap and allow coolant to leave the system.  I believe that is the source of the old
myth about water flowing through the radiator too fast.  In other words, the coolant loss happens first, followed by overheating,
not the other way around.  Some of the racers have reported measuring as high as 35 psi in the cylinder block (pump outlet)!

There's a tech note at http://stewartcomponents.com/index.php?route=information/information&information_id=11 with the same
explanation.

How much improvement you'll see is also open to debate, though.  It's kind of like the old saw about a chain only being as strong as
it's weakest link.  If lack of flow is not the problem, then increasing flow isn't going to help.  And if (for example) the radiator
is partially clogged (so it's the main limitation to flow) then a bigger thermostat isn't going to help either.

My own experiments in this area seem to suggest that flow is not the limiting factor on a TR3/3A engine, as long as the usual
components are in good condition.  The main limitation appears to be airflow through the radiator.  (Ditto for the Stags.)  Running
a high flow thermostat made no discernable improvement in cooling ability and I've since switched back to a conventional thermostat
with no discernable loss.

Of course, your car may be different (obviously the front of a TR6 is a lot different), and it's an easy experiment to try.  So why
not go for it?

If the water is too cool, the thermostat should close back up, thus
limiting the effect.

On the subject of cooling; can't the car run hot when the timing is set incorrectly?  IE: maybe not a cooling issue at all?

My hotrod buddies turn a regular thermostat into a $30 "performance"
thermostat by drilling a 1/8-inch hole in the flange of the
thermostat. Having seen an actual in-the-package $30 "performance"
thermostat, I can confirm this. I cannot confirm if it makes a damn
bit of difference.

Not all that murky.  I was asking questions about my newly purchased TR3 
on rec.autos when I got an email from a guy named Dale (if I remember 
the name correctly).  He said he was starting up a British cars email 
list and asked if I wanted to be part of the mail group.

Dale worked at Apollo Computers and set the server up on a company 
computer.  Dale owned an MGB.  If memory serves his MGB lived in a 
narrow dirt earth one car garage.  He eventually gave up the car because 
he and his wife could no longer comfortably sit in the vehicle. I don't 
remember where the british car mail list went after then.

In early 1990, the Land Rover mail list (LRO) was the first to split off 
from the British car mail list.  I was there art the beginning of both 
lists as twakeman@hplabs and [email-masked]@apple.com

I have the opportunity to get a high flow thermostat for my TR6.  I compared the diameter of the portion that actually opens to a standard thermostat, did some area calculations, and came up with approx. 10 square millimeters larger on the high flow.Question is will it do anything.

not the other way around.  Some of the racers have reported measuring as high as 35 psi in the cylinder block (pump outlet)!<br>

<br>

There's a tech note at <a href="http://stewartcomponents.com/index.php?route=information/information&amp;information_id=11" target="_blank">http://stewartcomponents.com/index.php?route=information/information&amp;information_id=11</a> with the same<br>

explanation.<br>

<br>

How much improvement you'll see is also open to debate, though.  It's kind of like the old saw about a chain only being as strong as<br>

it's weakest link.  If lack of flow is not the problem, then increasing flow isn't going to help.  And if (for example) the radiator<br>

is partially clogged (so it's the main limitation to flow) then a bigger thermostat isn't going to help either.<br>

<br>

My own experiments in this area seem to suggest that flow is not the limiting factor on a TR3/3A engine, as long as the usual<br>

components are in good condition.  The main limitation appears to be airflow through the radiator.  (Ditto for the Stags.)  Running<br>

a high flow thermostat made no discernable improvement in cooling ability and I've since switched back to a conventional thermostat<br>

with no discernable loss.<br>

<br>

Of course, your car may be different (obviously the front of a TR6 is a lot different), and it's an easy experiment to try.  So why<br>

not go for it?<br>

&gt;   I changed my clutch slave cylinder and bled it.  Went for a drive and<br>

&gt; after sitting in a drive through a few minutes had a heck of a time getting<br>

&gt; it in gear.  I learned a long time ago<br>

&gt; not to take the car out of gear in situations like that.  After some<br>

&gt; crunching of gears I got home.  On advice<br>

&gt; of one more experienced than me I re-bled the thing with my son pushing the<br>

&gt; pedal and me under the car.<br>

&gt; Finally after seeing no more air bubbles and having a good amount of<br>

&gt; resistance I went for a short drive.<br>

&gt; Returning home and about to turn into my driveway I had to crunch the gears<br>

&gt; again.  More fluid was added and<br>

&gt; more pumping etc. I felt confident.  I got to the end of my street today<br>

&gt; before I had to do a U turn and come home.<br>

&gt; I wonder whats wrong?    There are different spots on the rod into the slave<br>

&gt; and frankly I don't remember<br>

&gt; which hole I have it set at.  Would changing that make a difference?  Should<br>

&gt; I go to the hole nearer the<br>

&gt; slave or father away, should it come to that.  Ideas, opinions, prayers?<br>

If the water is too cool, the thermostat should close back up, thus<br>

limiting the effect.<br>

On the subject of cooling; can't the car run hot when the timing is set incorrectly?  IE: maybe not a cooling issue at all?<br>

My hotrod buddies turn a regular thermostat into a $30 "performance"<br>

thermostat by drilling a 1/8-inch hole in the flange of the<br>

thermostat. Having seen an actual in-the-package $30 "performance"<br>

thermostat, I can confirm this. I cannot confirm if it makes a damn<br>

bit of difference.<br>

Not all that murky.  I was asking questions about my newly purchased TR3 <br>

on rec.autos when I got an email from a guy named Dale (if I remember <br>

the name correctly).  He said he was starting up a British cars email <br>

list and asked if I wanted to be part of the mail group.<br>

<br>

Dale worked at Apollo Computers and set the server up on a company <br>

computer.  Dale owned an MGB.  If memory serves his MGB lived in a <br>

narrow dirt earth one car garage.  He eventually gave up the car because <br>

he and his wife could no longer comfortably sit in the vehicle. I don't <br>

remember where the british car mail list went after then.<br>

<br>

In early 1990, the Land Rover mail list (LRO) was the first to split off <br>

from the British car mail list.  I was there art the beginning of both <br>
