I liked "forgetting sarah marshall"

Quote from DragonCommando :

@ W4H
exactly, more throttle = less vacuum, which will lead to more air volume entering the engine, and at a higher pressure, even if the engine doesn't accelerate.

@ssm
I realy don't want to go through explaining how vacuum controlls an engine.

I think that I know what I am talking about.

Quote from ATC Quicksilver :

Very well, just need to be a bit more careful than LFS but its nowhere near as hard as GPL or GTL. I'm entered in the 11pm race at Lime Rock in the Solstice, not qualified, just hoping to have a safe race and not get caught up in someone elses accident again.

I thought that GPL was a little more forgiving then LFS. GTL is even softer.

Actually, I just downloaded a bunch of movies, I thought that Wanted was really good.

I love the last line: "what the fcuk have you done lately?"; I find it very meaningful

Quote from Mikkomattic :

I know that the behaviour I described in my big post was essentially correct, but the physical explanation might be lacking or wrong. I want to know the exact truth more specifically, so here's the question. Try to answer as briefly and layman-ish as possible (so that I might pass it along to non physics majors)

What causes the wheels to be harder to lock up the faster you are going?

I am assuming that if the tires have enough grip, and the car is going fast enough. The intertia of the wheels and car would overcome the grip that the brake pads have on the brake rotor. That is only my hypothesis, don't hurt me.

Quote from DragonCommando :

I realy don't know how to explain it so you will understand, it's kind of frustrating.

If the pressure is lower inside the intake, then you have less volume of air, because at 1 atmosphere that volume of air will take up less space.

meaning that it's the opposite of compressing the air, if you compress the air, then at 1 atmosphere of pressure, the air will take up more space.

This is partly why an engine makes more noise with the throttle open as it does with the throttle closed at the same RPM, because the engine is getting more air/fuel, and thus better compression and ignition.



not to be an ass, but most of that has been suggested a million times, and discused untill dead.

Sorry, WAT?!;you lost me at "less volume". I think you need to retake your Freshman year, specifically "chemistry 101"...

You also have to update the engine sound file and tweak the engine to redline at a very high rpm. You also have to factor in heat damage. If you stay at redline for long, you will melt your engine and you will have to do a rebuild. Then we need to add virtual money so that the people who drive a rotary engine equipped car can then have their virtual bank account drained while trying to maintain their car.

No it doesn't, the cockpits in GT5p are leaps and bounds ahead of LFS.

That's because PD made replicas of the cockpits of the actual cars. LFS has the same deal with certain cars. FBM for one, is a replica.

Quote from Bob Smith :

Not in the strictest sense, as the brake bias will be set to reach the limit of the front tyres first, so more rear grip isn't useful. The extra aero drag will help slow you at higher speeds though.

I meant something like this:

Quote from wheel4hummer :

Well, I am talking about the volume of air after the intake. Because the volume of air that is sucked into the intake is smaller, and then the air contained in that volume is expanded when it is sucked through the intake tube and throttle body. So if you mean the volume of air that starts out outside of the intake and then is expanded when it gets sucked into the intake, then I agree. I just realized where I may have been really confusing. lol

Okay, first of all... I don't get why you brought up the "same volume of air" argument. It only confused people, and it was pointless. The cylinders are going to expand to a certain maximum volume every stroke, OF COURSE it is going to be the same volume.

You were annoyed at people misunderstanding you because: a) you are talking about the dimension of the cylinder, or b) you are talking about the amount (moles) of oxygen going into the engine. Option a is so obvious and stupid, it is ruled out as we read your post. The second one was even more confusing but there was the possibility that you didn't understand about the structure of an automobile engine. You can't blame people for misunderstanding you if you are going to post stupid things like these, Captain Obvious.

Second of all, this is a BIIIIG tangent to my original post. I just wanted to post a suggestion for some improvement ideas that might catch the attention of the Devs. I lurked about the older forum posts a bit, it looks like many people are ALSO looking for brake fading. I am hoping that brake fading, "sponging", and damages will be included in the next update.

Quote from danowat :

No ABS as far as I know, maybe you have "Brake help" turned on?

I have "Brake Help" turned off. Apparently, I am just good at braking...

I got "pro" for all my training sessions...

I actually think that "Brake Help" means the driving line thing that appears when you press "4".

Quote from amp88 :

Is brake help on in the options (Options -> Driver -> Brake Help)?

It's more difficult to lock wheels at high speed in cars which produce downforce because the downforce increases tyre grip. As for the xrg, perhaps you just have the brake force set too low?

So... if I put a large lip spoiler on my car, it can potentially help me with braking?

Street Racers (08). It's okay, kind of lame, but it's better then the Fast and the Furious franchise where they distort racing concepts.

Brake help... Interesting... I will fiddle with that tomarrow morning... I am kinda busy with some stuff right now...

I understand that this is a "true simulation" and is "hardcore". With no driving aids or trainers or safety webs for drivers. But I seem to notice something about the brakes on certain cars. I think it's most noticeable in the Formula BMW.

There seems to be an "Antilock Brake System" effect when I slam on the brakes at speeds 65+ mph. I do not hear or see any skidding when I slam on the brakes at higher speeds. It also slows down very dramatically and quickly. I thought that it was just that the FBM did this because of the immense amount of grip present in its front tyres. Though, it is ALSO very apperent in the XRG as well.

Anyone have any comments on this "problem" or "bug"?

I would use an xbox 360 controller, then save up for a good wheel such as a G25. I wouldn't use a bad wheel.

Sure, okay, it's the same volume, but what does that have to do with anything? We are discussing about the amount (moles) of oxygen and petrol we have in the engine block. I don't know why you brought up the issue of volume...

I was worried that Hummer wouldn't understand the function of an internal combustion engine. So I made an analogy.

Quote from DragonCommando :

Its not.

But what you said doesn't quite make sense either.

The faster the engine revs, the more air and fuel gets taken in, and the farther open you keep the throttle, the higher up the vacuum balance will be, so the engine will suck in more air, but the vacuum will balance out and maintain the speed of the engine.

How is that not relevent? The more load, the more fuel you need to burn to reach a certain engine RPM.

Okay, I got a new setup uploaded! Now with wider countersteering and improved stability and flexability.

Quote from danthebangerboy :

I think it would be so much more realistic if parts of the car could become detached, ie, fall off, instead of squishing into the car, and also, things like windows and light coulld break. Last of all, if you are driving an xfg and get bad damage on the back of the car the window wiper sticks out whilst the rest of the car folds inwards. Clearly a blatant safety issue that should be adressed!

Yes, it would make things interesting to make parts fly off and become obstacles for other drivers, but I am mainly going to focus my rant about more critical damage modeling. Mainly being damages on important parts of the cars. Tires, rims, brakes, and gear box. Aerodynamic damage, throttle jamming open, and weathering would be nice too.

Quote from wheel4hummer :

Well actually, what I meant was that, "It takes in the same volume of air no matter what the throttle position or RPM is. The higher the RPM, the faster it is pumping." Because amount of moles of a gas and volume are two separate things.

Try lifting your couch up to your chest, now lift a pencil up to your chest. Same amount of energy expended?

What is your budget? I got the X-Box 360 controller, I am pleased with it.
