Heat Soak Issues with M3/M4?

There are 100 octane pumps around socal, so we're covered here too

That is not a given. If the heat extraction capabilities are sufficient, there is no reason for it to heat soak.



That is an interresting and valid point. I was running 94 because it is readily available here That could be the reason BMW recommend running at leat 93 (with 91 being the bare minimum).

I became very jealous last year when I saw 94 octane in a regular gas station near Calabogie. What a great track! Maybe I will go back next year!

CMP is a great track, very technical and fast. I enjoy it very much. Too bad it so rough on tires.

In Quebec, we are lucky enough to have 94 readily available at every Petro Canada station

Arguing with idiots is like playing chess with a pigeon....

No matter how good you are, the bird is going to shit on the board and strut around like it won anyway....

I don't doubt you didn't get heat soak if you had 94 and are driving at 80 percent for 30 min.

For the idiot that commented below: are you seriously comparing an f80 m3 to a race car? Obviously turbo cars can be built to run endurance races, and not have this issue. But they are RACE CARS. Or Porsches. Bmw f80 m3 is neither a race car or a porsche. Without octane or pussying the car around track you will notice a loss of power. With that being said- im completely aware that you were driving on a racetrack. You could be out there for hours with the tape on the front of your car and taking it very easy and never notice a drop in power. Street driving/ the type of driving you do on track I don't think you could achieve heat soak issues. The car has sufficient cooling for that.

You're right, I need to stop playing chess with pigeons

Why don't you go buy one, take it to the track, and see if you can heat soak it with your superior driving skills. Seems like all of us have just been pussyfooting it around tracks. Make sure to post your videos and lap times (like we have) so we can compare.

Well that's dandy, especially on 91 octane. I may put 8 layers of blue tape on my car and pussyfoot it around tracks, but at least I'm smart enough to use higher octane.

It does not give him the right to be arrogant and insulting.

I do remember him well from the E9X forum.

I use ms109 for the race car. F80 is a fucking street car. I said it'll
Heat soak. Especially if you're not running high octane. Anyone that was argues that is wrong. End of
Story that's it.

We'll mine didn't heat soak with 95 octane, so that's probably the difference (or the fact I drive real slow like you said). Yes I know what race cars are, just didn't agree with your blanket statement that turbocharging doesn't work for racing.

When you implied we are all slow drivers because we weren't able to heat soak the F8x.

It would be like me walking into a gym and calling everyone weak. It may be true, but it's a real dick thing to do.

Never said turbo cars can't be race cars.
That would make zero sense. I said the f8x with heat soak if driven hard enough. That is the case with 99% of turbo cars. Fully built race cars and most most turbo Porsches don't have this issue. Also octane doesn't make it not
Heat soak. It just makes it feel better. Heat soaking retards timing, higher octane helps with this. And I never meant to tell anyone that they suck at driving and I'm better.
I haven't been driving for long and I know that there is a whole lot to improve on.
