N54 water to air intercooler street build

[RSL]

I think that one in my post there was just a suggested table for Jake to use for something else, but I'll double-check after work.

For the fan, that table sets fan speed based on difference between ambient temp and IAT, so you can kick up the fan to pull air through IC or heat exchanger while atopped/crawling. IATs heat up with no/little airflow, so you can bump the fan regardless of what it would normally be doing for engine cooling. Once you're at about any speed though, the fan isn't going to make much difference.

@JohnDaviz are you on IN or IK?

I wouldn't mess with anything in here for water pump or thermostat controls really (PID, etc.). You can play with targets/thresholds, but I'd just use the MHD flash time for overall engine temp scheme, it's set pretty well already. For the intercooling fan request, it took me a few tests to find a balance. 100% fan moves a lot of air on 335is, but if you get too aggressive on temp diff/fan speed, it will be screaming almost any time you're stopped until after you get moving again, once the IC gets to temp.

I haven't tested/confirmed all of these, just included pretty much anything I already had defined in INA0S, so use at your own risk.

thank you very much!

Sadly this project has come to an end after an unfortunate accident! After the insurance settlement I've decided to move on, almost all upgraded parts will be up for sale soon, please stay tuned.

Thanks for the idea, this seems like it is worth trying at least!

Have a street flash with maybe 20% min duty cycle and then a drag/dyno flash that would run it full tilt non stop.

I’m really wanting to do this with my 335i 2007 can you message me for help or text @502-909-4653

I have since decided to restore the car therefore I will not be selling any parts other than those I still have up for sale, thanks.

what exactly are you trying to do? I am not sure that I really ever got the fan duty cycle entirely sorted out.

Soon we will have a lot more definitive answers on this retrofit

 

[JohnDaviz]

That´s awesome. One day i will start this project also.

Soon we will have a lot more definitive answers on this retrofit

What were the questions again?

I just checked the S58 Cooling tables.

N54 stock i think is known. So i played with the breakpoints and made this table:

I set the +1 and +2 DC a little higher than on the S58 table. I don´t mind hearing a little fan noise.

I have some questions about IATs
Has anyone ever removed the intercooler and just used meth for cooling?
I ask this question because I have twin hydra HP650, intercooler 7.5 no name and two nozzles of 750cc for the wmi 100% meth
my IAT are between 16 / 19 degrees celsius, which I find really very good.
I wonder what the figure will be without the intercooler

bringing this back from the dead, anyone interested in fabbing up a set of RHD outlets + chargepipe for A2W conversion?
i am half tempted to hack something together with a set of upgraded outlets + silicone hoses since i cannot weld but if someones willing to fab me a set of pipes i would rather pay for that

Finally finished my version 2 of this system with a new heat exchanger, cowl intake for the rear turbo and custom quad pass S55 charge cooler.

congrats thats an achievement. got pics of the cowl intake? they are good for inspiration, too bad you are selling the car already though
