More Overheating at the track for the 335i

T Bone · 10-02-2007, 07:14 PM

See http://www.m5board.com/vbulletin/sho...d.php?t=104598

Note the comments on the overheating and how the temps were relatively cool. You guys might want to ping him on his observations.

Please avoid M5 vs. 335i or 335i vs. X discussions as they will not iluminate anything more to the overheating issues.

Whats interesting... ive pushed my 335 pretty hard on the track... wasnt a super high speed track but i got upto 60 on certain parts (stayed in 2nd for the most part) and did it for a good hour and my temps didnt go past like 275

I spent an afternoon going at 9/10ths at Autobahn with their 335i's. 20 min sessions. 3 min breaks. Total of 4 sessions. Temp with oil cooler and auto tranny was 300F. With heat and defrost blaring. Any chance this is mainly an auto issue? The gentleman reporting this on the M5 board must have went through the exact same type of session I went through with the 335i.

Good question, PM the OP on M5board.....

Sucks to get to need to get the heat / defrost going.....this should be reserved or emergencies only....

I'm curious too if they were autos. I got my 6MT w/ cooler up to 285-290 in 90-95ambients. Got there damn fast (lap or two) and just held.

Dascamel · 10-02-2007, 11:23 PM

80 degree ambient, auto, retrofit, easy to hit 290+ after 20 minutes of going hard.

id say its going to happen w/ autos more often for various heat reasons

My cooling mods worked amazingly on my last track day, little heat soak ftw, but I deffinatly left the hood open afterwards still

E90ice · 10-03-2007, 12:29 AM

I am disapointed with BMW due to this issue. It'a a real shame!

maybe a sprayer

or the second oil cooler (or was that walked u)

AA has oil coolers w/ all their superchargers, dont know why they dont develop one for the 335 as a bolt on, would be easy enough to tap into the lines right next to the filter

Check out the thread again over on M5board...

the overheating cars were autos....

Dascamel · 10-04-2007, 11:45 PM

Its easier to keep constant power on the auto, feels like boost is never lost if you try hard enough.
