I remember reading somewhere (may have been here, maybe not) abut vehicles having a break in period where as after a certain amount of mileage is put on the car, you would reach optimum horsepower for that car.

I'm sure that GT4 has this also. Proof? I bought a Subaru Impreza WRX STi '94
used with 6.2 miles on it. The only upgrade I've done is change the oil. Before oil change, car has 267hp, 227.76 ft/lb torque. After changing oil, hp was about 274. Now, after putting 82.9 miles on it, hp has increased to 280 and torque is 239.19.

My question is, does anyone know how long the break in period is? and what is the max mileage before the car starts loosing hp?
 
Actually, the break-in period in real life is more about the time when an engine is new, it should be driven slowly at low rpms for a few hundred miles. This allows the pistons and cylinder walls, among other things, to adjust to each other and work themselves in and loosen up a bit which will give you slightly better horsepower, but mainly it's to increase your engine's reliability. I've noticed that a little in GT4 about the power going up as you drive it, but the power also goes down after you've put a few hundred (or thousand) miles on it. My Minolta dropped almost 50 HP! I think it's just something they might have put in to make it a little more interesting, like the rigidity refresher plan.
 
Well, if they have that in there, it is lame without going any further with it. If an engine's performance degrades with the number of miles on it, then we should have an option for an engine rebuild somewhere in the game. Now that I know that, I'm wary of driving cars in-game that I can only win once. :nervous:
 
i say phooey to power loss. i dont care. if i have a one of a kind vehicle, im going to drive it hard and abuse it. i took my S200 rally car to le sarthe and ran it into the ground for like 25 laps. i lost 13 hp, but it runs like a champ

yes, there should be an engine rebuild (or something similar) option....
hopefully in GT5!

Yes. "I have a couple of million credits in my bank account. Could someone rebuild my Audi R8's engine since it have lost some horsepower? Oh, no? Well I think I just have to buy a whole new one for 4.500.000Cr..." 👎

Haha...I totally agree. I haven't driven a lot of my prize cars yet partly for this reason. (The other reason is I just haven't had the time). Also, since when can you not increase the displacement on a big-block V8??? This is something that's pissed me off since GT1.

Yea you can increase the displacement of almost any engine IRL- just changing the con-rods or pistons can do this. But OH NO, GT cant have this for very car - so its Nissan Skyline only. Typical. Not only are there stupid numbers of them, but it has to get special treatment to boot. 👎
 
It's not like a small drop in horsepower is going to hurt anyway. I mean, everyone complains about the AI being so crappy; right? So what's the difference. An oil change and the rigidity refresher plan get it back to 99% peak performance....

My MINI Marcos GT had its displacement boosted. :D


:rolleyes:
 
I think GT5 needs a total custom shop. Design your own frame, pick an engine, do whatever you want w/ it as long as you have the money. That would be sweet!
 
Haven't you guys learn anything from GT3. Decreasement of horse power was in GT3 ALSO. It's smart not to do anything to your prize cars, but change the oil and unless you absoluty have the time/money or skill to get the car back any time you want. I only race prize cars when I completed the game. I make a duplicate copy of the memory to another card as back up. Then test the prize cars out and run them in the ground to see how far it can hold up.
 
please dont tell me you do that!!!
gawd!
drive every car like you just stole it!
thats what i say! :D
its only a game and the 10hp you lose you cn make up for in skill anyhow.
and to those who tune the hell out of cars: whats 10 hp on a 1000+ hp skyline :p
 
Isn't that why there's the port polish and engine balance thingy? Similiar to an engine rebuild. You should do the port polish and balance after a few k's when the engine starts losing power.
 
its just a game cmon guys, 10 hp pshhh dont let that stop you HAVING FUN DRIVING THE HECK OUT OF THOSE CARS!! i mean its not like you live in the gt world and its something that important. go have fun

seriously...
i have too many cars, i dont drive one too much, i like to switch it up a bit 👍
 
I have seen no power increase on a new car, unlike GT3. I have put a fair amount of mileage on an Audi A4 Touring car and have seen no increase in power. Unlike GT3 prize cars and new showroom cars have the same power. I compared a bought Aston Martin DB9 with one that I bought and the power was identical.

The new cars have 5% more power than the high mileage used cars and the oil change adds 5% to a new car or takes an old car to within 5% of an identical new car with an oil change.
 
Funny. I thought an oil change restored the car to it's peak power. I change the oil after every endurance race. My Minolta has roughly 1220 to 1250 BHP at thestart of the race, and has dropped to 1118 by the end. But an oil change bumps it back up. I haven't noticed any particular permanent decrease yet. Not sure what mileage it is on though. Probably about 3000 miles.

If I understood it correctly, the theory stated that every car has a optimum hp based on a percentage of the cars total hp, with or with out mods.

Let's say for example, you have a car that has 100hp. An oil change adds 5%, so now you have 105hp. The car itself has a max(optimal) hp of 113hp (with only an oil change). That optimal would increase by whatever percentage is programmed for the car and adjusts accordingly with mods.

An oil change will not just restore your car to a set hp. It takes into account engine wear. So your engine wear caused a 3% drop in hp overall, the oil change would then increase by 5% over that number, not the original number.

I hope that makes sense, its been a long time since I red all of this. I wish I could remember were I found it.

If you take a new car and drive for some time, the hp will increase over whatever it was when your aquired the car. I'm not so sure it that is the same for race cars though. They may be broken in since they are already built for racing/high performance.
 
i just race the hell out of the cars. i dont care if theyre 10 to 20bhp less, i just enjoy driving them. cars are there to be raced, not for looks (except the specials of course) so use them!
