Tested and Ready 70° and 75° Thermostat

Hi Pklasuer,

If you can't, or won't explain why myself and others shouldn't be concerned about potential downsides, then how are we supposed to read this as more than snake oil?

Without a doubt you are correct with your statement and
my apology.

I made a mistake, I should have said that its easier for
me to explain over the phone rather than typing. From
there rather you agree or disagree and take your gut choice.
I get calls periodically from E46M3 people for suggestions
and if I were to reply via typing I will be sitting on the computer
most of the day.

I suggest you to read the first 3 pages for 10min out of your time
and then call me I will sent you PM with my phone, its so much
to say about this which I did via previous replies.

My understanding is that you're selling this as a product, correct

And yes and no. I initially put this custom part together when
I rebuilt S54s as part of the entire package I do offer. But more
than happy to offer this to people.

PM sent.

Regards,
Anri

This is not truth. No additional wear and I can prove
this scientifically but to convince single individual I have no desire
to spent time typing a long post.

I was thinking very hard if it was a good idea to share this
on public place but rather with close friends only.

I am more than happy to see more head gasket failures
coming to my shop between 5-6cyl...LOL

My understanding is that you're selling this as a product, correct? It seems worthwhile to explain the efficacy of a product that allegedly improves on thousands of hours of BMW R&D. How come they didn't chose 70C? Were they wrong?

I know you run a prestigious shop, and I appreciate your contributions to the forum, but I usually approach deviations from stock like this with caution. If you can't, or won't explain why myself and others shouldn't be concerned about potential downsides, then how are we supposed to read this as more than snake oil?

Additional wear on the street in some form from running colder?

Very interesting. What are the downsides for a dual-duty car? Additional wear on the street in some form from running colder?

I still have AC and my car definitely gets toasty on track despite having an all new OE cooling system. Can't remember numbers, but the gauge gets up against the red if I'm pushing in 90+ ambient temps depending on the track, though the manual says that's expected.

I will give a week of waiting to see if more people will join
and will ship at ones.

Thanks

Sent with my choice

To take full advantages from the 70C Sachs Fan clutch is a Must !!!

I can supply that as well. Let me know if you need that.

I'm in. Will send PM. I'm due a cooling system refresh so now is the perfect time.

[Anri]

I edited the post so re-read it with additional information.

Those who are interest in this reply with your name or
sent me PM with your name address etc.

Thanks,
Anri

Digger,

Endless cases were people take advantages from lower t-stat
are in every car brand. Engine Dyno, chassis dyno, track list
goes on and on..

Sapote has very wrong concept what the meaning of "Running-Cold"
means. How much heat S54 generates and the issues of running
hot on Bank-2...

May be I should cancel this in order to have more S54s with upcoming head
gasket failure...on Bank-2, keep them coming baby keep them coming
I don't mind all...every head gasket failure is all welcomed :-)

Sometimes you just need to let things die and allow others to interpret and make their own decisions. I think everyone is in agreement except for 1.

colder just makes more power. There’s a big difference in torque

Love RH videos, he does about as good as anyone could expect with real back to back testing.

Well, if we want to use this example as the proof, then the gain in HP is only happened at around 3300rpm, and nothing to gain above 5000 rpm for this engine.
Btw, he also pointed out that the air fuel mixture was optimized at the beginning which was the 116F run. What happened if he tuned the mixture for the 180F run? Not a fair comparison isn't it?

We all agree that cold air give more power, but it's not a good idea to keep the engine cold in order to have cold intake air, as cold engine block robs power (it is physics). Someone should be using cooled intake manifold instead.

There was a gain at all rpm just less at higher rpm compared to gains at lower prm and not a zero gain which makes perfect sense. It certainly doesnt show that hotter makes more power like you claim.
The fuel and timing was optimised for each run not just for the first run thats just silly if youve seen Richard's videos he always does that and its why he uses a standalone ecu.

Nobody is saying to keep the water cold and you gain 50hp but running it cooler is better for power. 70c on the skin is not fun so its not actually cold it’s just colder than 90-100c. also rubber and plastic bits are sure to last better

there are other videos but they are behind a paywall so cant view them anymore

Digger,

I realized we are wasting time and energy here...
