Tested and Ready 70° and 75° Thermostat

[Tonggi]

just to give everyone an update. 70c tstat is great. def keeps temps a lot lower when cruising around the streets. at the track it didnt make a difference of course since the car gets to temp and hot. But it did cool down the motor a lot since it will keep kicking through the radiator up to 70C versus the OEM.

But Im not sure if its the only thing since I also updated the radiator and fan clutch

PM'd Anri about a 70C thermostat


Update: I was able to get his phone number from his Instagram Bio and order it that way got a reply same day on a Sunday. I will update as well when it ships so others have an idea on lead time.
The price now is $220 Shipped.

Hello Anri,


Good way to argue. Congrats!
On the big racetracks in Germany I haven't really seen a s54 with the viscous still in place.. I wonder why?
btw. I really like to hear actual numbers, on the aftermarket fans we have exact airflow numbers at specific static pressures to compare.
I'm open for discussion, would love to change my mind if I'm not correct! Always interested into learn something new.

In my opinion in no way the viscous fan running at idle could deliver anywhere the same airmass near a good aftermarket fan. You can even hear and feel the difference.. And this is what I'm personally aiming with a electric fan conversion, coming to a stopp or in traffic after spirited drive to bring out the heat.

how much power do the SPAL fans people are using on the e46 platform have?

Hello digger,

at 20-30amp depends on the model as far as I know. And if you're willing to do some modification to the cooling package, there are 45amp+ variants available.
But it's not all about the power, blade design is also important.
Depends what efficiency window you aiming, there are different options available, for me it's important to get as much as possible air on a low static air pressure (aka standing) to get the heatsoak/IATs down on the FI s54.
On a racecar this is maybe very different, I don't know I don't really drive on track, just interested in the technical backgrounds.

Spot on.


I wander how aren't you tired to reply
after all of those years to light posts lol..

I'm calling that BS. Spal fan ≠ Spal fan. So I HIGHLY doubt that a a near 40 year old technology e24 AC fan moves more air (regardless static or in movement) than a powerful Spal fan (No Spal slimline fan). Also these are imo absolute durable, if you use sealed one. Many times proofed on trackday cars, that get a lot of abuse and heat.
Just for reference, on a FI S54 street car, electric fan conversion made massive difference regarding cooling, compared to the rubbish viscous fan, even it was renewed in the last 10k km.

Hi,

I don't recommend the 55C t-stat on daily driver
cars with occasional hard track days.

70C will give the perfect amount of heat in the engine/parts
for daily driver without triggering the check engine light.


The only and single electrical fan conversion I personally
would use is one from E92M3/E60M5. The fan blades size,
the motor size are all designed to work in the harshest
heat/enviorment, also the harness gauge.

Every single E46M3 owner I have seen converted to
Electrical fan is one from Spal.

The Spal fans are garbage in a sense of how much
air they can move...The Spal fan is worst than my 1988
E24 AC-Fan.

Those fans seem to be ridiculously over priced. I have no doubt as to their performance though coming from my X5M.
