There are several guys running 400+ hp in their E90 (same engine and trans) and doing lots of track days, hard launches, etc. It does eventually takes its toll but I don't plan on doing qtr miles so I don't have any real concerns.
As long as water and oil temps stay in check there are no worries. The 335 guys make no changes to the radiator but some do add another oil cooler but their stock one a s tiny little thing. Our oil cooler is the size of our radiator. We also have a transmission and power steering cooler (I don't know if the 335s have those or not).

Thanks for posting this. I am considering relocating my meth pump to get the line down lower, more to the level of the nozzle or below. I get air bubbles in the line overnight and have been unable to find any apparent leaks. There is lots of space in the front corner to mount the pump similar to your set-up. Do you have any issues with air leaks?
I figured air would get pushed through the line if it is below the nozzle, that way purge itself while driving.

I havn't had any issues. It does seem like a few dribbles leak out of the tips and I get a minor bubble or 2 but nothing that has affected anything negatively.

Hey everyone... I just got back my car yesterday, and I wanted to share some pics of my trunk mount setup. Erik from Rathmann Auto Works did the job for me, and I love it. Here's a link to a thread with pics: https://5series.net/forums/diy-do-yo...2/#post1481766
