Engines are designed to run, not being pampered. They are built with durability. Even though redlining is considered "not healthy" by a lot of people, as long as the oil is changed regularly, you'll be ok. by the way, some engines are designed to have more power at higher revolution, the heat and friction will still increase the wear of engine parts. try to have fun, engines aren't fragile at all.

 

Your question is to redline it "constantly" meaning everytime and the answer is YES which i mentioned on my earlier post but will be subdued to wear and tear due to heat and friction. 4B11 is a strong engine but not a bulletproof "race" built engine. Thats the reason there's a lot of aftermarket race parts in order for us tuners to replace them and have more performance on the vehicle (i.e. higher than Redline revs).

I think "Frequently" is the much more suitable word for that. you don't want to pick a fight everytime. Use it when its needed.

Well, enough answers have been given and its up to you to pick you think is the best one. That is your car anyway... peace out!

 

It is not uncommon for people to compare engine with a person's heart. So same thing, you shouldn't baby it, yet you can't strain it. It needs a good balance of exercise.

 

Hearts remodel themselves with more muscle fibers with exercise, there are biochemical changes that take place to make the fibers more efficient at using oxygen conversion of fatty acids to energy....similar things do not take place with engines, they just wear more.

 

I did when i first got it now im trying to baby her

 

But then thats like saying you should not drive the car, preserve it in your garage, and just turn it on once in awhile so grime doesn't build up...

On a standard car, doing a lot of full throttle action and down shift to redline could drastically reduce the life of the engine but cars that are built for performance come with stronger internals and can take some punishment once inawhile. Probably would last less than babying it but it shouldn't cut the life of the engine too much.

 

wow...no wonder most of the evos out there are tearing up all the time...this is not a good way to drive any car...unless you are racing for a team and they are paying for it when it breaks...lmao

 

LMAO to that 1

 

Don't worry about it.

Seriously.

A mechanic once told me to think of my engine like a door. Does opening the door to its limit too many times "break" the hinges? Of course not. Now, if you're holding the door with pressure right at the limit of the hinges, then they might eventually break. But, opening the door "halfway" and opening the door "all of the way" doesn't really hurt the door.

Thats a good qoute. Is this the same mechanic that forgot to put your oil cap back on?



Kidding

 

I agree the cars are made to take some abuse...but the question in the thead title is "is it a bad idea to redline the Evo X contantly"...the answer has to be yes.

As much as we like the pretend, these are not race cars, we do not have a team of mechanics that can tear them down and rebuild them once a week. Hell, we used to replace the rings and rods between qualifying day and race day because of using 500 more rpm down the straights during qualifying.

 

i thought you lose power the closer you come to redline. I thought the ideal shift point was around 6500 rpm and after that the power starts to die off. if you are stock there is no point to redline the car.

 

 

There is very simple response to the OP question and it rests with longevity. A racing engine lasts ~1 year with full time circuit use, not everyday racing but weekends at least. A DD can last 10 or more years with "spirited" driving even AutoX stuff on a regular basis. So running redline on a DD brings you closer to the 1 year cycle rather than the 10 year cycle. You have to decide just how close you want to come to each.

Well said.
