Anyone running JB3 with the pre oil cooler versions of the 335? My build date is 10/06 and I do not have the oil cooler. I think it was in early 07 when the oil cooler was standard. Will I have any issues running my JB3 in my car in terms of temps? I have been adapting it all weekend and haven't gone past 240 degs, but I haven't done any extended driving (over 1hr) in higher temps (over 85 degrees).

Do you think there will be any potential issues running it in more 'harsh' type conditions? Or even a trackday with outside temps to be above 90?

I have had the JB3 for 5 weeks and have had zero problems, I also have a build date of 10-06. I have driven to AZ and back to CA with no hiccups, and about 5,000 miles. I'm thinking about getting an oil cooler just to keep things totally under control

Your car will most likely have limp mode induced by high oil and water temps if you dont have any oil cooler especially if your going to track your car or drive it under more "harsh" type of conditions for a prolonged period of time. Even with an OEM oil cooler your car can reach into the 300F mark.

Just buy an oil cooler and save your car. It is a worthwhile investment to say the least.

[Terrance28]

Can't you just complain to bmw and they give you an oil cooler?

[uberschnell]

If your car included the Sports Package then you can complain and get the oil cooler retrofit for early model 335's. I know because that's exactly what I did and had one installed. The oil cooler was only equipped on cars that had the sport package. I'm not sure if that's the case still. I have not heard of one person who did not have a sports equipped car that has gotten BMW to cough up an oil cooler retrofit for a non-sports equipped 335.

As a side note, having owned 6 BMW's I can say one of the most important things I've learned was to always get the sports package. In the case of the 335 it's paid off big time.

To the OP, if you have Sport package, talk to BMWNA about an oil cooler retrofit.

I don't have an oil cooler (no sports package), and I run JB3 just fine. Temps never go over 240F, even with hard driving in temps at around 100F. I will also get an intake soon.

So, don't worry, you should be fine.

My 08 coupe with the oil cooler runs around 240 when driving around town. My 07 sedan with no oil cooler generally runs cooler than the coupe in everyday driving.

It depends on how hard you push your car. If you drive it around town or on the highway like you are on a race track, your oil temp will increase. Try driving from 90 to 140 and back down a few times and you'll see what I mean.

You will without doubt, no questions whatsoever, experience high oil temps on a track day with no oil cooler and more than likely experience a limp mode after around 15 or more minutes when the oil temp breaks the limp threshold.

I don't think any tune will make your engine's oil temp run hotter, however, to the extent that the tune itself causes oil temp related limp modes. If you push your engine with or without a tune, the oil temps will increase.

Thanks for the information, I've done a track day with just the SSTT (outside temps were in the high 70s that day) and had no issues with oil, was just curious if running the JB3 would 'highlight' the high temp situation.

I've spoken to BMW of Fremont and they said they cannot/would not do a oil cooler retrofit (I've requested it through my SA numerous times).

MAGNA3 - which dealer did you go to? is there a SA that you can refer me to get it as I do have the sport package?

As for driving around, my car is typically a weekend car, and I like to drive it hard at every chance I get (which isn't much when you are in the city), and I currently never really got above 240 with the SSTT or stock.

[uberschnell]

^^It was a dealership in San Mateo (think captain hook).

I first tried the dealership. At first they had no clue what I was talking about so I walked the SA out onto the lot and up to an identically equipped 335 and pointed out the oil cooler. Still no luck so I made a quick call to BMWNA and within a couple of weeks the Manager from the dealership was calling to set up an appointment to do the retrofit.

I think this is really out of the dealerships hands and is done more as a good-will gesture by BMWNA, who covers the cost. Keep in mind my car is an e90 AT w/ Sports Package and that starting right after Jan/07 similarly equiped cars came with a factory oil cooler.

[Mr. 5]

Terry's car (the owner of the JB products) does not have an oil cooler in his 335.
He has run 11 second times with his non oil cooler so there's something to be said for that.
Now, track driving is a little different but I would be interested to see what Terry's 335 would do.

Ah, I see...what did you say to BMWNA? Do you think I should go to that dealer and ask for an oil cooler retrofit saying that I don't have one and that post Jan07s do? The Fremont dealer said that if I'm not running high temps, there is no worry. Since my car is a 10/06 vehicle, I'm not sure if I'll be as fortunate as you with a car much closer to the oil cooler vehicles. Also, do you have the # for NA? Thanks for the response, it has been helpful.

I didn't know that Terry's car was a non oil cooler 335, yea I'd like to get an idea of the JB3 on the track with the non oil cooler to see if it even has an impact, it seem as if the oil cooler isn't really needed, but just a back up back up plan in case things go wrong?

[Vince@ V K Motorwerks]

I thought terry has a 135i. At the dragstrip, you sit there, push your car for 11-13 seconds come back around a wait again. Your car has plenty of time to cool down before the next run. I always find it amusing to see how many people shut off their cars, and push it forward in neutral in order to keep their cars cool. Its not like your hot lapping at a dragstrip.

He has both an E90 335i and 135i.

Terry has had a 335 since the very beginning of his JB tunes, and this was the car where he ran the 11 second time; And, he wasn't pushing his car up to the line either . He has pushed this non oil cooler car to the max and it's very surprising with how well it has kept up with the others. Or, should I say the other way around.
He purchased the 135 so he could perform testing with the V81 ECU.
I know what you mean though. I'm going to race the Roval at Cali Speedway on the 21st of September so I'm going to see how the stock oil cooler will perform.
We shall see.

Don't deal with your dealer directly, they don't really have any control over the oil cooler installs. If you have a pre-March 07 build, which it looks like you do, and you have sport package, which you haven't said yet, then contact BMWNA and tell them your situation. If you don't have sport package, then you are pretty much SOL on the BMW courteous install and you should get the VKM oil cooler if you feel you need it. But as long as you are not beating it at the track (not drag strip, but actual track with curves and turns) then you will probably never run into a situation where you need it.

mine comes with OEM intercooler

works great , love it

My Sedan has no oil cooler. The day before running at Famosa Drag Strip, I was cutting the canyons with the sport bikes. Got warmer at the top of the canyons, but I can't honestly say how much an oil cooler would help. My oil cooler equipped 08 seems to run warmer in most given situations.

If you are not the original owner of the car, they are not offering the oil cooler. I just spoke to BMWNA regarding getting the oil cooler for my 07 335i (10/06 build with sports) but they refused since I am not the original owner.

According to them it is only needed if you want to go to tracks. So far in normal city driving oil temp stays below 250 so I am not that much worried right now
