Hi there,

I have a kinda stupid question . If we accelarate our TL to a red line not all the way...but just a middle of red line, what's the impact on our car? I know if we keep doing that we'll destroy the engine. My question is: if we do it occasionally, will it hurt the engine also? I am freak now.....because I've been doing that for 3-4 times already . I don't want to spend money on if the engine breaks!

 

You will not kill the engine. If you do hit redline, like I do occassionally (while racing), then the engine will cut off power for a split second. It is a safety feature so that you can't over-rev your engine.

But to be on the safe side, try not to get to red-line too often.

 

I'm sure as with everything else mechanical, the engineers have designed enough safety cushion at the top of the redline that will prevent any serious damage. That being said, it is probably not a good idea to go reving it up to mid-redline 4 times a week unless you don't particularly care about keeping your car long.

 

You probably won't hurt your engine as long as the oil is fresh and you use synthetic oil and so on. Also' I wouldn't redline an engine until I've driven for fifteen minutes or so. Just my thoughts.

 

Redlining your engine every now and then won't do any harm. However, if you do it regularly you will eventually damage it. That's what redline means!

 

I think redline really means it. You aren't doing your car any favors going over redline.

 

There are some if and or buts to this point.

If you are just running it up through the gears and you are hitting redline, say 7000-7200RPM. And you are doing this with a properly maintained engine then there should be no real concerns.

But if you are running it up to redline and either holding it there or letting it backdown from there you are creating a LOT of stress on the engine and other drivetrain parts. Not recommended.

Personally, I hit 7000 to 7200 from time to time and have done so in previous cars I've owned. None of which ever experienced any engine failures. Maybe I'm lucky, but some engines where built to rev and Acuras are one of those.

Also, anyone look closely at the dynos of the 3.2 and Type-S? On every Type-S dyno I've seen them produce effective power over 7000 RPM before cutting off. I find that my best runs come when I take it to 7000-7200 in 1st, 2nd and 3rd. If I let the car shift or if I shift at redline I find that I don't win some of those races with fast or faster cars.

I would caution folks who buy their cars used not to redline them. Unless you know the previous owner drove it that way. Used cars, especially those driven "gentally" and with higher mileage are not going to hold up as well. This is something I learned long ago.

Well, to be honest.. here is my 2 cents...

I think it should be okay to rev the engine... sure the engine will not last as long. But it's not a good think if you never rev it as well...

Most cars today come with ECU that will keep you from damage your engine... except with a 5 spd and you miss a shift...

I am pretty sure that if we remap the fuel curve, reprogram our ECU and do some minor tweak, our engine car get 300hp easy, even 400hp is possible, stock... but it will maybe last you for 2 hours...

it's like F1 car engine is tuned to last only that one race...

our car is tuned for durability... and it will last... as long as you keep it in the factory spec...

 

What do you think the rev limiter is for

IMO, thats the true redline of the engine...I haven't hit it yet though...too scared my engine will die on me just as the warranty ends

 

The car won't even let you get into mid area of the red. Its just there to look pretty. Nothing to worry or talk about Once you pass the first few lines, the engine cuts fuel and spark to every other cylinder in a patern to create a soft rev control to keep something stupid from happening.


In Park or maybe N, it won’t even let you rev close to red line by over 1000RPM away.

 

i dont think that you will hurt anything by reving your engine past redline but from what i was always told when you hit redline everything past that you are actually losing hp so why rev pass redline...unless you are racing and dont the neddle go past redline but you should know your car enough to feel when it is time to shift.....just my $.02....

 

Uhm... your car shifts 1st-2nd automatically.

 

just don't leave it in SS and think you're driving in auto!! That's why they changed the 1-2 shift to auto for 00 and up. It was due to stupidity. Blame the 1-2 auto shift on stupid people of this world!!! Otherwise you 00 and up guys could have had the 1-2 shift as a sportshift.

 

hey nate, the 99 tl allows you to redline every gear even though there is only 4 gears.

 

Yeah, aint that Auto mode and SS mode a pain.

And of course that's why I shift manually when racing someone.

I thought that's what the rev-limiter was for.

It is true that there's no point to go above the redline becuase you past the peak hourse power output already and shifting is better then keep on revving.

However I do believe that if you remap the fuel curve, and do some tweak here and there. your hp peak will be at a different point of the rpm (can be higher or lower depends on how you tune it).

 

I think that the bottom line is that you will be fine as long as you don't do what is displayed at the very very top of this page.
