I finally found a 97 twin turbo supra in the used cars, red one real nice, anyways i put a full exhaust and chip in it changed the oil. it had 37200 on the clock.
I take it out for just a few kms of drag racing and testing with traction control off.
and low and behold in just 20 short kms i lost 4ps unrecoverable. from bouncing it of the revlimiter, coldnt even get it back with an oil change.
So dont let some fool drive your prized rides and redline em for long.
A little redline is ok on many cars.

But if your bouncing of the RpM limiter Your doin damage :dunce:
 
engine damage like this was in gt3. personally, i experienced almost no performance difference. with the hp gain from changing oil the first time, and the engineware, there isn't too much of a final change. its not like your car is undrivable and you cant ever use it again.
 
:dopey: Some of these details I hear like this irritates me because it's a damn game. I realize that they are trying to make this as "realistic" as possible but I believe there are some "realistic" things that should be left out. I'd like to just play the damn game then play and run out of gas. If I want to have my engine explode or run out of gas I can do that in real life at any time.
 
If I'm not mistaken, this can be repaired.. some sort of engine rebuild, tune-up.. I think they call it a "Refresh"... that will restore the original horsepower from a damaged engine. Dig around the translation screens and/or the manual.

Allow me to make a little correction: HP permanent drop in GT3 comes from mileage, not from overreving your vehicle. I can't remember the exact number, but it happens really early too (within the first 500 miles), while GT Tester had 37200 Km (I assume) which is 23115 miles (roughly). Overreving your vehicle in GT3 has no effect whatsoever, as the only drop you get is if your oil gets dirty (recoverable HP - just change the oil) or if your vehicle has xxx (again, can't remember the number) - in this case the HP drop will be permanent, and there will be no way to recover it (except buying/winning a new vehicle, of course :D - and that is if the vehicle was not unique (meaning you can only win it once) to start with - in which case you will just have to deal with it).
But yeah, I agree, the drop is not that big of a deal, unless you are racing for the fastest lap possible (like in an Online Competition), in which case, for psychological reasons, I'd rather have the full HP amount, rather than knowing I am driving a not optimized vehicle... It makes a little difference as far as lap time goes...

EDIT: Ok, since I don't like spreading uncertain information, I actually bothered looking it up... Check this thread: Everything you always wanted to know about HP, break in, and oil changes
It explains, well, "everything you always wanted to know about HP, break in, and oil changes" :D It also explains how many miles it takes for the break in to occur, and how many miles it takes for the permanent drop.

i'd agree on that,it makes you feel a little uncomfortable knowing that your car is not in top condition,so can anyone confirm that in GT4 is an option to rebuild your engine???

thanks for the details. I bashed the redline even on the Viper in GT3. This new feature will help me much in GT4 knowing I will lose even 1 hp drives me crazy.

No problem. Check the "EDIT" too, as it links to the thread that explains it all 👍

And to both of you ^ Yes, it drives me insane, too. It's okay for in-game play, but for the WRS I only want optimum vehicles. Or else I will always be thinking: "I could have gotten a whole better lap time if I would not have had the HP drop" (well, not a whole better, more like a little better, but you get the picture) :D

I like that. It's a bit more realistic. Redlining a care ISN'T necessarily a bad thing. But bouncing it off the rev limiter is. And repeated abuse will certainly damage an engine. Thanks for the heads up!
 
don't know if i'll like it or not,if you can rebuild your engine than it's cool,but what when after 2 years of GT4 your unique race car has 75 hp?

play arcade mode, it should be as realsitic as possible.
 
you can only rebuild chassis not engine
I would care less ... since most prize cars can be obtained again and again
except the license test prize cars
so I trashed one, I can go get another one with B-spec
btw, I usually test drive stock cars in arcade mode
then my car in GT mode will stay 0 mileage
 
Like somebody once said, doing a chassis refresh replenishes HP. Give it a try and see if your HP returns to normal.
 
I distinctly remember someone saying that they purchased a used car (but did NOT drive it, so they never lost any actual hp), then took it in for a "Refresh", and it popped up saying "197hp---->197hp" (or whatever the hp rating of the car was). Which means this Refresh DOES, in some way, affect the engine. I think there was no change because the user in question didn't drive the car first.. he took it to Refresh as soon as he bought it.

The only way to test it would be to take a car that's lost horsepower through usage *Looks over at GT Tester*, perform a refresh, and see what happens.
 
Nice tips I found here. And I noticed it my self by the way.
Maybe it sounds stupid but in GT3 I have 2 the same Subaru's.(Impreza WRX STi Sedan) The one with +2000 on it and the other with less and its true they are both fully tuned and the one has 550HP and the other one has 520 or so I thought. It's strange. I can't bring them up to the same HP.

Isn't the rev limiter supposed to help prevent engine damage?

Without the rev limiter your friend could go way into the redline, hold it there, and ruin your engine (quick like you described).

I really wonder whats going on here. Could it be something else?
 
I don't think we're seeing "damage" so much as "wear and tear", which was already present in GT3. It just happens faster if you routinely bounce off the rev-limiter in a used car than it does with a sensibly-driven new car.

I'm still waiting for someone to test the Refresh to see if the engines can be tuned-up/rebuilt to their original specs.
 
I'd like to see someone test a fresh car against the exact same car that's been degraded. I'm curious how much of a difference it's doing to make in lap times or 1/4 mile times. I woudln't expect 5hp to do very much, but a drop of 30hp might be significantly noticable.

Yes, it does. It keeps you from completely over revving the engine to a speed parts can't take. It does not keep you out of red line, drops you a couple of hundred RPM. Damage can still occur from keeping the engine spinning at its max speed for an extended period.

View the limiter more like a caution. It tells you that you should probably shift if you haven't already.

And I know this from autocrossing, not just looking at the game :dopey:
 
Actually, yes. Damage a small internal in the engine, and watch what happens. lose some compression in a cylinder, intake, exhaust, valvetrain issues. Lots of little things can go wrong. That will cause a slight change in the power by reducing engine effincency...
