Heatsoak at the track...

good to meet you too! Yeah that pic makes the car look lowered...

Car was the quietest of all...

Was that low flying f15 strike eagle? Dayyyyaaam!

My car will be tracked, so both of these mods will be necessary.

Guess you could re-route the head light washers to the intercooler? I know on MINI you could buy a bezel that attached to the IC and re-route the rear window washer to it and use it when you needed a little cool down. Never bought it or knew anyone that tried it but it was a cool concept.

If you're going to go to all that trouble, might as well take full step to methanol injection and directly cool the intake charge.

Methanol injection in the combustion chamber is not the same as cooling the intercooler. These are apples and oranges!

It's a big jump from spraying a little water on the outside of an engine component vs. actually injecting something in the combustion chamber.

You are not sure how the OX sensor will react to Methanol. Artificially cooling the charge could confuse the engine management as the engine running rich and lean the mixture or even allow it to advance to the point when the methanol cuts off, it could detonate.

I'm sure in a full blown race car with careful attention to engine management, etc. this would be a great solution but it's not even in the same ballpark as the simplicity of spraying distilled water on the intercooler.

Yes, of course they are different. However, they are both means of cooling the intake charge.

There are now several very sophisticated methanol kits with robust failsafe mechanisms on the market. If you want to check what seems to be the "state-of-the-art" system for N54 motors, you might want to google the Vishnu Tuning Procede with PWM methanol injection. Pretty amazing and well-engineered.

I was on the track (Ring) this weekend and I am impressed by the cooling. It is big difference compared to the 335i I had before.
Oil temps never went above 125 Celcius, going down to 115 (which is normal operating temps) before I even have arrived on the parking.
My 335 in stock mode I would have on limpmode within one lap on the Ring, with Power Kit within 2 laps. Even with a big Oilcooler, FMIC and airduct I as hitting 135 degrees Celcius.... Really happy.

Beig a fellow track junkie.....

that Jersey wall sure does come up at you fast when your on the throttle coming out of that turn...doesnt it !!!!!

[Franklin Joseph]

haha...actually the wall this direction is less intimidating (there's alot of room).
The other direction, its an off camber 180 degree turn that's much closer to the wall.

+1. I like simple for the DIY projects!

Towards the later part of the session, engine temps got close to 3/4, i'd guess maybe 280 degrees...car didnt go into limp mode, but i noticed it didnt pull as hard as the early part of the session, i assume this is heatsoak?
I was in 3rd and 4th only, revving upto 6500rpms at certain parts of the track.

will the intercooler help with the heatsoak?

PFC01 brake pads were awesome, no brake fade at all.

thanks

It's most definitely the FMIC heat soaking.

We have spent countless hours on the chassis dyno with our 1M, doing a back to back run will reveal that the FMIC is getting heat soaked with elevated IAT's and the results were much less hp/tq output.

Even an aftermarket FMIC can only do so much...It will eventually heat soak as will. Typcially on the very hot summer day out at Auto Club Speedway, WSIR or BWR an aftermarket FMIC will heat soak about 5 minutes into the session(high boost levels) and the lack of power is very obvious. To combat that the use of meth injection will help or a spray bar to cool off the FMIC.

I had a home made water spray when I had my Subaru WRX.

There's a few DIY articles on waterspray on this website
