Brake boosting at speed
Anyone able to get their cars to brake boost at say 40mph in prep for a roll on race? Seems everything i try the car just cuts power...feels like it doesnt like the throttle and brake pedal pushed together. Either im doing something wrong or these cars cant do it. Thoughts?

They do not like the status of both pedals being pressed, it assumes you are inadvertently stepping on both and will ignore the gas pedal so you can avoid an "unintended acceleration" toyota crash. It may be possible to enable via tuning but I am not sure.

Durability wise probably not the best for the turbos as that's what takes the brunt of the abuse when brake boosting or using antilag...the system basically retards timing forcing combustion to happen later in the burn cycle as the piston is moving up in the cylinder forcing the actual combustion process into the exhaust and turbo housing.
some cars that cannot be tuned with an antilag system typically will brake boost to achieve the same outcome...seems like ours cant however.

We don't have the option to turn traction control completely off for the C450, no matter how long or times in different sequences you hold down the traction control button, you either activate or deactivate only (please someone correct me if they know a way to do it). I guess you could try it on Dyno mode? I have never tried driving the car in Dyno mode because it also disables ABS, or put the car in Dyno mode at all for that matter. I personally wouldn't guinea pig this but it could help you achieve the outcome you want, I would consider this high risk for something breaking or snapping since most safeties would be off. Lol if you try, let us know.

Nope, that doesn't work on modern cars. The moment you step on the brakes it cuts the throttle and in case of AMG it will also temporarily reactivated ESP for as long as you are standing on the brakes. I know it's common race tactic, especially in Rally driving to be on the brakes and the throttle at the same time, but that doesn't work on today's street cars. All due to the idiotic unintended acceleration lawsuits we've had in the past.

Come on guys
It definitely works, first release the gas pedal, then using ur left foot to just tap the brake paddle very slightly and then hold down the gas(u will get a hang of it after a few trys) my c450 builds boost perfectly fine with this method.
The key is to press brake first!

I don't know why people are being complete *** about the OP. If you don't know what brake boosting is, go look it up. It's a real thing, albeit I don't think it's good for the internals of the car, but you can do it if you want to. I'm not sure about modern cars not allowing this because I've seen several videos of people doing it and the results are noticeable if done correctly.

You obviously have no idea what the intent of the action is trying to achieve, or how a turbo motor works for that matter, so perhaps take the time to educate yourself before posting a useless response to an honest inquiry.
its ashame really....i have no problem helping people on things they may not know but I'm at a loss on the sarcasm. appreciate the backup and agreed brake boosting isn't the healthiest for the turbos but if you want to maximize power/acceleration in the scenario described in my first post that's what it requires.

Hey @Boostman76 I'll give it a try with dragy over the next week (weather pending) to compare 60-130 with and without brake boosting to see if it makes a difference (measured difference not just butt dyno saying it works).
Disregard the sarcasm, the real drivers or car enthusiasts understand and know what you are talking about. I've only had the car for 6 months and had also be wondering if and how well brake boosting works on these cars. Before I could be in the right gear and just dump the clutch to get the car into the power band quickly. I may end up just repeating what @superswiss states but we'll have some evidence to back it up.

Heh, I know this is a year old but did you end up trying it out?
