For anyone who is following this thread who doesn't have an oem oil cooler, and wants a unique opportunity to do a custom cheaper retrofit set up, I have just the solution for sale:

http://www.e90post.com/forums/showthread.php?t=589988

This would allow someone to be a pioneer, and attach a large core with a fan, so we can see how that will help reduce temps

Do you guys overheat the water primary or oil?

What CFM does the stock fan flow? All the stopping and going on a track requires a good fan to cool for the amount of time spend under 45MPH and during turn in as the air vacuum created when hard corning doesn't cool the rads efficiently.

I've used these fans before which flow alot more air then other fans...

http://www.zirgo.com/
The 16" flows 3000+ cfm.

What Oil cooler does the SETT kit use or the AR design?

I found an application chart for the setrab oil coolers. http://www.jagg.com/pdf/Application_...ons_112610.pdf Also I found the cooler which is listed at 450-475 HP listed for 259 on ebay.

Just curious if there are bigger coolers that will fit the stock location.

You should read more or there should be a sticky for known good setups. This would essentially be the spreadsheet we've all contributes to.

Stett or ER oil coolers and distilled water with Mocool or Water wetter PERIOD. This will allow you to have consistent laps so you can practice and get better.

You can do other mods but these are essential if you ever wanna challenge pro Miata drivers on twisty road courses.

"Welcome to the club" doesn't quite sound right but you're at the right place

1. When you can, pull those codes so we can determine the cause of your limp mode(s). The fact that you got them off the track too, following the event, suggests more issues than just water/oil overheating (30FF, 30FE, vanos, intake valve etc.)

2. In the meantime, as others suggested, for future track events:
- turn off the JB+
- log your coolant temps (1st post explains how)
- look into using distilled water + WW instead of antifreeze

that'll get you a long way towards having a limp-mode-free track day.

Actually do a solenoid bypass, and turn up your juice box plus to 50-70%. That way even if you get a limp mode, you will just drop down to stock power, not 1/2 of stock power. Next simply buy a $139 peak research tool R5/FC3 and read, your codes. When you know what your codes are, report back to us. BTW, if one of them is 30FF, then do the solenoid bypass, and it should stop being thrown.

1. I am currently in the process of trying to obtain a BT scan tool. When I removed the tune, I didn't get the issues anymore...

2. Yes, I will run without the JB+. I will log the coolant temps also. For this recent track event, I flushed my coolant with 25/75 coolant/distilled water. I will try just distilled water and WW next time.

Alright guys, quick question for everyone. I see the first post says that you don't need to worry about doing a track day, but I have one of the few E92 sport packs with no oil cooler. I plan on attending a three day HPDE school with the BMW CCA next month. Outside temperatures will likely be in the 50s to low 60s (it's at New Hampshire Motor Speedway). How much risk do I run of encountering limp mode? The course itself is expensive, as is food/hotel/taking a day off/gas/driving there, etc. so I want to be reasonably confident I'll get my money's worth and not be on the sidelines waiting for my engine to cool.

Thanks.

How come you have the money for a THREE day BMW HPDE, but you don't have money to do an oil cooler retrofit?

Minimal risk. At 50-60F you should be fine. Keep an eye on coolant and oli temps and let us know how it goes!

The three day event is $500. From what I can gather, an installed oil cooler retrofit would be a couple grand or so. Also, I'm hesitant to spend money on one since it doesn't have an impact on my normal driving, I don't plan on doing much in the way of tracking the car, and I'm probably only holding onto it for another year or two.

So I might be trading my car in for a gtr tomm... Only thing that's holding me back is that gtr doesn't come in manual gearbox... Anyone think I'll regret it?

The GTR is at least 2 leagues beyond our cars. It's so much better.

You are the only one that can answer your question about the MT.

One of the handful of cars I can't catch on the track

Get the GTR and don't look back, as everyone else is saying it's a different class (performance-wise) altogether.
