Mazmart's New Product ! Lower Temp Thermostat !
#152
If you sincerely don't understand the benefits I will be glad to take more time explaining or even debating. If you have some other purpose to your negatively angled posts then I can ignore you and move on. I'm comfortable either way.
Take off the flame suit. I keep things cool in my environment

warranty hasn't failed you yet!
Dont' you hold the record for engines already?

The purpose of this thermostat is primarily to change the range of the 'Gatekeeper'. That's basically what your thermostat does; when the set temperatures are achieved the gatekeeper re-directs the flow of water (Or whatever liquid heat transferring agent) from the by-pass (Where it keeps circulating in the block avoiding the radiator) to the radiator for exposure to air, where it is able to ditch some of it's unwanted heat.
I refer to it as the gatekeeper because: It doesn't matter how good our water pump is or how good your radiator is if this control mechanism keeps trying to achieve 200 plus degF . If the gatekeeper sees 184 deg it starts going "Whoa, hold up, things are getting to cool around here!" and starts to close the radiator passage while opening the bypass.
Our unit is intended to begin opening at 169 degF and be full open at least 10 deg lower than stock. Our unit has a better transition as well in terms of how much area is open when the bypass is completely closed. The stock version is less than optimal in this regard.
Ultimately, the thermostat cannot stop a catastrophic overheat nor can it make up for other deficiencies (Bad or in-efficient water pump, poorly sealing cap,wrong cap pressure, low fluid levels, improper ccolant to water ratios, in-sufficient radiator surface area exposure, inop cooling fan/s etc) but it's a very important piece in the puzzle of creating a better cooling environment. On a really hot day if there is the potential for your cooling capabilities to be maxed out, then a lower range thermostat will delay that possibility. Essentially it is helping to maximize the effectiveness of other positive things you may do or have done; like a better water pump, a better radiator, better airflow, modified fan temps etc.
It's all synergy folks

The flame suit is merely because everyone on here seems to think this is a good idea but me .
Engines have an optimum operating temperature range . How do you know that the opening temp you have selected is within that range ?

I did read this but saying "it's an important piece of the puzzle" does not cut it in my view . Perhaps I missed a better explanation somewhwere in this thread .

Trust Mazda that they've chosen 'the optimum range' or trust me. It's a tough choice, I know.

Paul ,
I like your style man . Some other vendors on here would try delete my post or get all uppity over my comments .
I also like your other products and will happily buy from you .
This product - I do respect your experience and know you know a lot more than I do but i remain unconvinced ...

Brettus man--the oem 13B engine in a hot climate runs too hot. Well discussed and generally accepted. Like Paul says this thermostat is part of the package needed to keep the engine below 220F. It will also help keep it over 170.
I have dealt with appropriate cooling issues on this car for a number of years. If you can tell us what you are thinking is the best operating temps then maybe we can get a good discussion going
Looking forward to it--I will probably learn something.

I cannot see it helping with overheating one little bit .All i can see it doing is making it run cooler for those times the engine is not under stress - big deal .
Now if someone comes along and says they did testing that showed the engine runs more efficiently at a lower temp (ie more power less fuel comsumption) - i'll sit up and take notice .

lower than stock t-stat is nothing new. its used in all kinds of race cars.
it wont solve any overheating problem you might already have,
Just like other upgrades like Radiator, it allows the car to stay cooler for longer.

Thanks guys.
I got the thermostat installed. After I unbolted the air pump tube from the exhaust manifold (RB header)I was able to move it out of the way without having to unbolt the tube support bracket connected to the intake manifold. Next time I will blank off the exhaust manifold and eliminate the air pump!

Paul,
I have the Mazdaspeed Defi gauge setup with oil and water temps and oil pressure.
I will be at Summit Point this weekend with NASA and they are calling for mid eighties.
I have modified my car extensively so that I can drive it hard for 15-20 minutes.
Once I see 230 degree F(110 C) water temp I back it down.
My next mod is an undriven pulley.
