Will do. The guy that owns the ST car with the stock system loves to beat the $hit out of his car so that won't be a problem. LOL

Sorry, like I said earlier I'm not eloquent on trains after work.
Like I said earlier, it's your car. I was just trying to be helpful because not everyone knows that too cold = bad.

I'll shut up now, though. You've obviously got things figured out and a lowly fluid dynamics guy who spent his grad school years modeling ICE combustion waves can't possibly know how cars work.
Alright. I'm out. Curious to see where this goes and how your temps look when you push the car. I'm sure they'll be fine though.

Though if you'd be so kind to log pressure data i'd really appreciate it. No seriously, please? I'd like to see if Level 10's claim of the system self regulating is true.

Please don't misunderstand. I'm not questioning your intelligence or engineering credentials in your area. My area is OEM powertrain design and manufacturing and how to get these things to actually pass emissions and efficiency regulations and still be worth a crap so I have an inside track on these things. I have experience over a very broad spectrum whereas you are a specialist in a very specific area. I've been involved in numerous Simultaneous Engineering Activities in Japan with Nissan as well as Toyota and they always are a conducted the same way; model then test the $hit out of it, rinse and repeat. Then there's the issue with actually having to build it...quickly, like in 46 seconds an engine.
Every time we get into the testing phase of a new engine design, material or shape change, we almost ALWAYS have engines come apart on the test stand, regardless of what your Sophomore year Mechanical Engineering Fluid Dynamics textbook says. Have you ever seen an engine detonate after 8 continuous hours at redline? LOL. It always results in having to evacuate the plant and completely rebuild the dyno cell. Anyway, my point is, modeling only gets you so far. Real world testing that includes pushing the limits is and will ALWAYS be needed. My wife is an electrical engineer that does nothing but model missile flight trajectory and target acquisition software for a military weapons contractor. When her models finally do work, they're handed over to the application engineers to go out to CA and actually blow $hit up with. She always gets feedback on how to tweak the model next time to get a tiny bit closer. As you know, everything in engineering is an iterative process. She got up in the middle of the night last night because she had some sort of equation revaluation. LOL. Nothing ever works the first time no matter how awesome your equations and models say your design is. Anyway, good talk Russ and you might want to look into a better mode of getting to work

I applaud your efforts OP Some of these dudes need to get off your sack. You are obviously on the right track so I don't understand the hate. As mentioned, the only thing left worth measuring is line pressure. Once that can be tracked and accounted for, this mod almost becomes a no-brainer. Everything else related to temperature and what does/doesn't "feel" right at the end of the day will be user dependent, so there's no point in arguing that any further.

I also love how peeps tout manufacturer specs and recommendations when they have absolutely nothing else to grasp at. As if whatever turbos, dpipes, tune, meth, etc. they choose to run falls right in line with BMW recommendations

No hate, just making sure that everything has been accounted for in the design. I don't like seeing photos of exploded engine and transmissions. Also why do I suddenly feel crazy for trusting manufacturers spec on temperature ranges?

I talked to the machine shop today and the plan is to run 50 sets next week, If they can't get them done next week, it'll be mid December before I can start shipping them when I get back from Japan (I leave on 13NOV). So, for those that want to make sure you get a set, I'll go ahead and make them available for pre-order on my site tomorrow so all I'll have to do is start shipping when I get back.

Again, for anyone wanting to do this modification you'll have to decide if you want to leave the stock heater in the loop or not. Completely up to you.

Really appreciate all the requests for these through PMs.
I'll continue to post temp data here as it becomes available as well. It's raining here this weekend so no high speed/load data can be taken as was originally planned.

Here's a screenshot of the model.

So Any idea how likely they could get this out next week? Living in SF I really don't need the heat exchanger in the loop for warm ups and might bypass it so I can keep my setup a bit more clean (vs splicing the line)

Can you provide pics of the blocked coolant lines?

I'd give it a 50/50 chance but I'll try to push them to have them completed so I can ship the orders I have before I leave.

I'll see if I can grab some pics for you but you basically just cut the hose connector off the 2 coolant hoses and plug them with a 5/8" hose plug and a hose clamp. I bought both plugs at Lowes in the plumbing department.

The fittings are now available for pre-order on my site. They can be found here...

http://www.xlr8dmotorsports.com/bmw-...apter-fitting/

Like I said in the post above, I'll try to push the machine shop to have them done mid next week so I can ship the orders I have by Thursday. If not, they'll definitely be done by the time I get back so I can start shipping them immediately when I return.

Sorry. Which part? The fittings are currently being machined and I'm in Japan until December 11th so no further data has been collected. I'll be off for 2 weeks starting on the 19th so I'll be grabbing more data. It'll be pretty cold then so it'll be good data for you guys in colder climates.

Update on data collection...
This morning it was 30F outside so I took the opportunity to collect another sample of steady-state temp data. The ATF came up to temp in almost the exact same curve as before (ambient temp at that time was 65F) and leveled out at 65C (149F). Keep in mind, I have a 90/10 165F ATF TSTAT, which means there is always at least 10% fluid flow through the cooler core. Also, the oil temp was 95C (203F) with a 215F TSTAT (90/10 also). I'm very pleased to see that it seems everything is operating as predicted and expected so far.

Update on the production of these fittings...
Operation 2 of 3 has been completed and I expect to pick them up tomorrow. All that's left to machine is the hex on the collar. For those interested, they are already available for purchase on my site.

You mentioned there will be testing/comparison of trans temp with and without additional cooler and heat exchanger delete. Still curious to see that data.

Question...

Since the lower section in our radiators on AT/DCT's is used to cool transmission fluid, what would happen in the scenario on a head on collision where the radiator is compromised?

Will transmission fluid mix with coolant and vica versa?

I'm sure this probably isn't the case, but just a thought I had.

Just read through again, and you've answered my question already :p

Another tidbit of data...
It was 60F outside today and it took 12:18 for the ATF to reach 35C (95F) under idling conditions (650 RPMs).

Next up, I will test my system under track-like conditions on WG spring, which is 12psi for my ST. El Nino has been having his way down here so the roads have been really wet ever since I got back from Japan on the 11th. However, Saturday looks like it might be a good candidate for testing.

After that, I'll test the ST car with the stock ATF system under the same track-like conditions. Hopefully he can join in on Saturday if the weather plays nice so we can both test under identical atmospheric conditions. I'll continue to post all data I collect in this thread.

Also, the fittings are finished and all existing pre-orders have been fulfilled.
