Our cars overheat in stock form too if you go hard on them for a while. That's why we need an oil cooler too for track use.

My Z is kind of unreliable... What do you mean by that?

I've driven my car hard plenty of times in 90+ degree weather and never have seen oil temps above 223.

Drag strip is too short of a test

I love 335s. I always wonder if I would of been happier in a chipped 335, but I love my Z and my girl has a 325xi so I get the comfort fix when I drive her car...

But no lie, driving her 325xi def makes me wonder how sweet a 335 would be.. very confortable enjoyable ride. I drive is awesome stereo is fantastic, and even her 325 handles and feels great at alll speeds..

they are both top of the line tuner cars , love em both, nice runs...

223*F My bad.

I haven't experienced overheating either, as I don't track the car, but it's been pretty well documented that the 370 needs an oil cooler for serious track. That does not include short 1/4 mile runs that really won't do much since there is so much cool down time between runs.

I doubt that the overheating issues of the 335i are much different than the 370z.

my friend bought a tune for his car, and had to take it off because his 335i was overheating much easier. its not that it over heats stock, its just that bmw doesnt expect you to put 15 psi into the turbos without oil cooler

He must have issues with his car. I have a 08 E92 335i and my wife has an 07 E90. Her car didn't come with the cooler and I took it back to bmw and had them add it. So tell your bud to do that first off!

Secondaly I've never had issues with the car overheating on either car *I'll swap my JB3 over to wifey's car when I don't feel like shifthing*. When running it hard oil temps will get to 250 but that is normal. Now what I do experience is heatsoak which hurts power output due to the smallish intercooler. Some people do run aftermarket OC's but they still experience high oil temps when doing track events *not drag racing*.

I went to Car & Coffee in Irvine with my friend and next door neighbor who has a 335i 6mt putting down 410whp. He has a full Brembo GT BBK, custom tuned, front mount intercooler, intakes, full 3" catless exhaust, and coilovers. I was really surprised that my Z with just Stillen sway bars and some exhaust work was able to keep up in the turns because his tail was getting happy while I was just tracking perfectly through the turns matching his speed. On the straights, he annihilated me but no as bad as I initially would have thought.

The big weight is the achilles heel of those cars, but there is no denying how well rounded they are.

Jeffblue · 08-24-2010, 03:38 PM

a 335 really puts down 340whp with an ecu tune?

RCZ · 08-24-2010, 04:28 PM

Yeah, if they were modded then you didn't stand a chance. I know of a few guys pushing close to 350 on stock turbos. I raced and beat a slightly modded one when I had full boltons and was making 310whp. Not by too much though...they are quick cars when modified.

ky0u · 08-24-2010, 04:44 PM

My friend has a 2007 335i and jb3 in it. It's a piggyback tune thats capable of adding around 80hp/80tq . There are several maps that you can switch between, the higher ones can only be used if you have accompanying mods but the lower ones are accessible even if the chip is the only thing you have. It's still quite capable as a stand alone mod though.

Problem is, like someone else said, the cars dont come with an oil cooler (at least his didn't). Bursts at WOT are fine but the car heats up really fast and if he runs the car hard for an extended amount of time, the car goes into limp mode.
