Right now you have installed for all intents and purposes an intake manifold heater I suspect.

So you miss your WRX maybe?

i want to make sure the intake air is nice and warm for fuel-efficiency gains.

Also i run without the underbody cover because too lazy to remove every time i need to get under there. surely that is messing with something as well.

m18 system. way too much power for what i need it for but snagged a fathers day deal. very slick. https://slickdeals.net/f/14112341-mi...archBarV2Algo1

Well now that you have the M18, you can use it as a impact and remove the 16 bolts that affix the belly pan to the undercarriage . But really, too lazy; with that setup as a strut bar? Before you just had to remove one bolt and loosen the other to rotate the bar out of the way to add oil to the engine. Now you have to basically disassemble all the bracketry you rigged just to add engine oil.

oh that would be terrible

on the strut bar, luckily there's enough space to open the cap and fit a oil nozzle so no need to remove

Efficiency? I was under the impression that it's ideal to bring cold air into the engine in order to cool it. Why did you kill the integrity of the brace by drilling holes in it? Ghetto, Trailer Park or not thought out, yes.

So you must have rotated the cap so it flips back towards the rear. Or use a different cap altogether.

Those holes effect on integrity is negligible at best. Bar is pre bent and those bents are its weakest points.

Alright boys, back in business. 200 round trip today. Well see how she do.

[ryan stewart]

Needs an intake burrito to work.

Also are porsche959dadscar and slowcar the same dude?

[Welcome to NBA Jam]

Will be curious what your oil temps are before/after. It's not a good location for it at all since there's pretty much no air flow, but your install is just so darn clean that it looks like it supposed to be there and I'm rooting for you.

Apparently. He self-pwns his own car just to troll everyone? lol.

Oil temp seems slightly better, but could be because of new rad. Hard to give credit to oil cooler though. Was peaking at 270f now it’s closer to 260f and takes longer to get there and even if I push, it doesn’t seem to get to 270. Downside is it takes 2x time to get to operating temp but that’s to be expected with all coolers.

Doesn’t the stock oil cooler have a thermostat in it?

Also, the water to oil one from the F10 both warms the oil faster and cools it well. I hope to do that one some day.

Even in-bay I would have expected more of a drop than that, tho, bummer.

Not good in cold climate.

Barring cars that spend a lot of time on track, an exchanger style oil cooler (such as the F10s) is one of the best all around options... very simple as well, no need for a tstat since they help heat the oil when below coolant temp, and cool it when above. The faster the oil gets up to temp the better, anything that slows that process down could be considered detrimental, potentially more detrimental than 10-15 degree higher oil temperatures. Modern synthetic oils can take an absolute beating, you'd be amazed.

And yeah, the OEM oil to air setup does have a thermostat...240f I believe

Yes it has a thermostat. I’m running the oil cooler set up from a N54 with the oem thermostat and it warms up in same amount of time as without the cooler.

When I pushed the car in summer I used to see 260+ temps and now I never get it to hit 250. (The stock thermostat opens at 240, btw)

If someone wanted to do a functional cooler set up on the cheap I would highly recommend the N54/55 cooler set up from a wrecked car.

You put the heat exchanger probably in the wort place in the engine compartment for several reasons:

- It is at the highest level in the engine compartment where heat is most likely to get trapped.
- The location has very poor airflow.
- The heat exchanger is horizontal, which makes it even less capable of receiving any airflow.
- It is right under the hood, which in the summer serves as a solar heatsink and absorbs the sun's heating of the hood sheet metal.
- By cutting an opening in the lower section of the cabin air filter housing you've now allowed for: (1) a pathway for engine heat to pass into the cabin through the HVAC system, (2) a pathway to let engine vapors of oil and coolant enter the cabin through the HVAC system, (3) now have a pathway for water to drip into the engine compartment right onto the starter and crank position sensor and lower electrical junction box that sits at the bottom of the intake manifold. This indicates that you don't understand that the cabin air intake system is purposefully separated from the engine compartment by the rubber seal that runs across the top of it and seals against the underside of the hood.
- The engine cover can not be refitted to the engine, thus leaving the ignition electrical system exposed to water, when it wasn't meant to for long time periods.
- The strut bar, which now holds the forward position of the heat exchanger now requires additional disassembly to add oil to the engine (just to make a point, that cheap-ass strut bar design is just completely FUBAR)

So my takeaway from this is you got a really nice Milwaukee drill and that's about it. Did you get the M12 or M18 system?

On the HVAC points, I think All the same concerns/potential issues exists with the BMS cowl filter mod? And that’s the filters are designed to eliminate.

Agreed. The design of the cabin air filter seals off the engine compartment from the cabin. The E46 is the same way.

Why do you think and state this? Coolant temp and coolant pump absolutely affect oil temp. Engine is primarily cooled by coolant that is moved around by the coolant pump. If THIS cooling system isn’t doing its job the oil temp will inevitably go up

[Torgus]

I can't believe the OP is serious...this is a joke right?

I meant it isnt directly affecting the oil temp like it does the coolant temps. Notice the latter part of my comment i asked why he hasnt replaced the waterpump if he is stating that is the issue?

I do have to ask why you think this is a marvel of engineering as stated in another thread. If this is such a good design as you have stated your approval and interest in then why didnt bmw come up with this as their solution for the N54? Instead the put their oil cooler in the bumper where it can receive air flow and be unaffected by rising engine temps.

You also claim that i have no ability to come up with original ideas for stuff such as this. Why would i come up with an idiotic design such as this when first off my car already has an oil cooler and second bmw has come up with a proper cheap and easy solution if you need an oil cooler.

What this guy has done with the oil cooler is how all great invention happened. Original design wasn’t as good but got sophisticated over time. Again, concept very foreign to you as someone who can only criticize other work that wasn’t able to do himself to begin with.
