Time and time again I want to give friends a ride in the 335, and I'm sick of having to drive for 15 minuites before the oil temp comes up. Does anyone make an oil temperature sender clamp? Is there any other way to bypass this lame system? I understanding wanting the oil to thin out a bit before full boost, but 200 degrees is wayyy overboard.

Interesting. I didn't know the car withheld boost until it warmed up.

I think bypassing is really bad idea and will definately sacrifice your engine health.

I don't think its too far out there IMO. Welcome to the wonderful world of turbo cars with oil coolers and lots of oil. My turbo S2K does the same thing, it takes a good 10-15 minutes to warm up with 6.5 quarts of oil and an oil cooler. The difference is that I am able to boost the car whenver I want since its a standalone ECU, but I choose not to boost at all until the car reaches operating temp. I don't think that any type of clamp would work since your vac tanks don't fill until your car is up to temp, which means that your wastegates are bleeding off exhaust and no boost. I could be wrong here, but I thought I read that somewhere. In any case, I think its a good feature.

If that's the case, can I just bypass the solenoid that is preventing the vacuum tanks from filling up?

Trust me I'm driving BMW's since 20 years now. Don't compromise in oil-temp's. That's why the 335i has the oil-temp gauge. Like the M3 E46.

[Terry335]

I know there are risks but say a friend wanted to try it, how would he go about doing it?

[e.n335]

I know and I respect. It could be a short & expensive try ...

All what these engines need are frequent oil-changes and their operating temps ( beside gas ). I never had any engine-problems.

Honestly, I have no clue... I don't see why you would want to boost before the engine is up to temp, its just causing a lot more wear on the engine.

Terry it is especially noticeable in my new buddies PROCEDE car! its night and difference with cold oil vrs warmed up.

Mine as well........huge difference

really? why? think about it for a minute, the metal parts themselves are heated up within minutes if not sooner, the oils viscosity is extremly close between 100 and 200.... so why? what factors are different? saturation maybe, but that has nothing to do with your oil temp, just time

Yeah, as long as the temp is up to 120 degrees or so I'm comfortable flooring it.

yeah on my vette i wanna see 130 auto tranny fluid temps and 150 oil
before wack'in it

yea i tried to explain in another thread the oil viscosity difference is negligable with synthetic oil, even from what it will start at here in florida, i tired to make a thread about it to discuss it, but no one will believe me without proof (which is why ive request viscosity test @ 70 120 and 200 for the sample i sent in this week)

there is more to this than just oil viscosity.

Everything in the engine and turbos is machined/manufactured to be optimal when at working temperatures. As long as much colder oil is going over all engine parts, I am not convinced that they are running optimally as tolerances, etc will be out from optimal.

Best to have your engine at full working temperature.

I don't know, i'm not an oil tester. I guess I just don't see it as that big of a deal for a few minutes of warm up or maybe i'm just use to it.

[Doccommando]

Failing to adequately warm up and cool down turbos is what kills them. Let the car warm up like you should.

that the thing though, oil does not pick up energy at a fast rate like say alcohol, it can hold a ton of energy but it takes a LONG time, thats why they use oil at power plants to transfer heat to boilers and at solar arrays and such, but its not a cooling device

Yeah, what you're trying to say is oil a has extremely high specific heat capacity

It takes very long to cool off, yet very long to warm up. Kind of like the ocean in the fall and spring.

Actually, no not like that. You were correct up to that point. The ocean takes a long time to change temp due to the massive volume. Specific heat is an intensive quantity, meaning it is a property of the material itself, and not the size or shape of the sample. Its value is affected by the microscopic structure of the material.

that deals with how much energy it can absorb, which i mentioned being high, but i was more pointing to the rate it absorbed it, which is low, meaning its not cooling the engine much

and even if it was cooling the engine a bit, it would still be operating at temperatures well within the range of a "warmed up" engine which are actually heavily varied, go open up your secret menu and have a look at #8


so, why?
