is this bad for the engine>??

 

^ive been wondering this as well. I know when I was younger and driving my moms car I raced a friend and granted her car was not turbo I held the brake and gas to load the engine and slipped belts and broke them lol barely made it home before it died and before it overheated from no water pump.

 

If your are already pusing the limits of the engine then yes, for extended periods it could be harmful, if your pretty much stock then you should be fine as long as your tune is in order.

 

Break boosting is bad, well, because you BREAK boost.

Brake boosting on the other hand, is really no different than climbing a steep hill in your car with heavy throttle. You are artificially putting a load on the motor using your brakes, so to you that say yes it is bad, explain to me how this is any worse for your motor than climbing a steep hill and I will agree with you that it is bad for your motor.

Thats almost like saying its bad for you to floor your car. The only thing that is going to take a beating by brake boosting is your rotors and pads.

This is true only for a well tuned car

 

If the car isn't well tuned then there are bigger problems. You shouldn't drive the car if it doesn't have a good tune

 

Its just using brakes to load the engine and dissipate them as heat. You run the risk of boiling brake fluid, warping rotors, glazing pads. Other than that no harm to the engine.

um ya, its horrible on your clutch.....HORRABLE…then again i also agree that it might not be much different then climbing a steep hill....eitherway i avoid doing it.

how is it horrible on the clutch?
my car is tuned on a dynapak hub dyno.
it's exactly the same as "brake boosting"
you can set any rpm and it will hold that RPM irrespective of engine load. (assuming you dont exceed the maximum torque limits)

 

It just puts wear on your brakes. As others have stated, all your doing is putting a load on the engine.

 

you can boil your brake fluid doing it for too long. I thought i could avoid doing high speed runs for my brake bed-in by just brake-(boosting) down the road. Well, pedal went soft and my **** was boiled.
