Engine braking won't give you more grip, I've had to argue that before as well. It won't make your tyres magicaly grip better.
But it gives you two things, both are important in a race car.
One, you can slow down without using the brakes, on some turns this is better because it doesn't generate heat in the brakes and will let you use the brakes harder when you need to without overheating. The less you need to use them, the less they will heat up.
Two, you can balance the brakes yourself, by modulating the throttle you can controll the distrobution of brake force front to back.
I've used engine braking for both of those in real life, My vintage bike has drums, so I need to engine brake wherever I can, but even disk brakes will overheat if you use them too much. I use engine braking to apply most of my light rear braking, the rear drum on my bike is used mostly for hard braking into turns. My front drum gets used for all braking exept where engine braking is the only thing needed to slow down for the turn.

I thaught about playing WOW for about two seconds, then I realized how much I hate what they did to the story line of War Craft and I changed my mind.
WC3 and WOW shouldn't have happend in my opinion, they completely go off of the original story line. I'm a big time old school gamer, and WC2 was the best of the series.
If that is real that kid needs help, just like many other WOW players. People have lost jobs over that game, it's simply unbelievable how people can get so addicted to something where you do the same thing over and over untill an expansion comes out, and then you play the quests from that over and over. Theres no real gain, its not like a ranked sim racer or FPS, where being number one means something more than just the time it took you to get there.

I have the same skid sounds, but the BOV needs a long gap at the end of the file so it doesn't repeat itself. Its anoying to hear it go psst psst, when it should only do it once each lift off.
That was some good drifting, nothing crazy, but you did a good job controlling the car.

Lack of engine braking on an H-shifter? what planet are you on?
An H-shifter with manual clutch will give you more control over the engine and allow you to double down as well. Engine braking is greater in lower gears so double down = more engine braking, not less.
hell, on cars with close enough ratios you can tripple down if you wanted, from six to three is one hell of an increase in engine braking if you are running short enough gearing.
As for Heel-toe, I mainly drive the LX4, FZ5 and XRR, the only one I realy ever use heel-toe for is the FZ5. The other two seem to be easier to balance and decelerate much quicker making it easier to just brake down to corner speed, shift straigh down to the gear for the corner and then trail brake in.
I'd assume that the internal values are limmited to a certain level, and they roll over after that.
So if say for instance the value can only go between 0 and 511, and 0.5 is equal to 255, and going to 1.0 will take you to 511, going to 2.0 will take you back to 511 and no higher.
Usualy if something is in a range between 0.0 and 1.0 it isn't supposed to go past 1.0, so it will be limmited internaly to that.

I honestly think if you want some mil-sim, go for Insurgency:M.I.C. It's a source mod so its on steam. You can download it directly from steam now too, provided you already own a source game.
Insurgency isn't perfect, but there isn't one combat game that I have played that's perfect, not even ArmA.
Insurgency has a minimal Hud aproach, so you only have what you need. Basicaly a compas and objective markers, and a mag count when you reload. No health and no crosshairs.
Some things arn't finnished, but they are actively working on improvements, and the sightless shooting is realy nice, the gun free aims untill you bring up the sights. The only thing that doesn't sight properly is the M203, but they are working on it.
I had a firefight that lasted five minutes, I was pinned down behind the hood of a pickup truck and had to wait for help. I only survived because I remembered that 7.62x39r won't go through an engine block, so I hid behind the engine.

I have a working prototype of my DIY shifter made out of lego and k-nex.
I ran practice laps with it for a while, it was somewhat reliable without a centering spring. With the centering spring installed it would just break at the base of the shift lever.
It only works for 6+R, no seqential. I might post a new thread with pictures of the k-nex internal workings and the lego shell/gates.

Does LFS's physics account for the drag reduction on the car infront as well? I'm sure it's been asked before, but does the car infront get a speed boost as well without bumping?
Steam can't cause a program to have errors as it only loads the files, it doesn't run them.
I have seen several games recently that work fine during the beta, but then the release version doesn't work correctly.
When Shadow Run (horrible game) hit shelves, it woulden't even start on most computers, it would just give people a blank screen. It took a few weeks for it to get completely sorted out.
Developers are depending on steam and other distrobution systems way to much for patching the problems after the game is released because they are in too much of a rush to get it shipped these days. Gone are the days of games being released in a stable and fully functioning state.

North korea hasn't had much luck with nuclear weapons. They seem to have the warhead technology, but the delivery system is still pretty limmited.
If they have another few years to work on it, and it seems no one wants to stop them so they will, it could become a threat in the future. But if they launch a nuke at anyone it'll probably be shot down and they will be bombed to oblivion before they knew it.
It isn't likely they could smuggle one anywhere important either, so that isn't a threat.
North korea is in a position right now that they shouldn't be making threats, but they still seem to think it's a good idea.

The variable geometry expansion chamber could be used to compensate for that a bit, and even then the change in port position wouldn't be very large.
Lotus seem to have a system for changing port size, and it appears to do it in a way that could be adapted and simplified to change port possition instead if you realy needed it to. But I don't think it would be critical as long as the cylinders don't lift alot.

Thats alot different than a simple thermal pad, and if it blocks the soldering joints then measures should be taken to insure that the soldering joints are done correctly before hand.
For the record what you are talking about is a heat spreader, NOT a thermal pad.
BenQ monitors are known to be failure prone, I would have not gone for that one.
The company my mom used to work for got seven of them while she was there. I said that four of them would be dead in a month, just as a prediction.
In less than a month four out of seven died as I had predicted, the rest went shortly after a month. Now it's just a waranty game for them, it fails, they replace it.

Wow you people baffle me again and again how you take things way out of context. New technologies are always going to be developed, but its how they go about it that is important. Simpler is the most important fundamental of design, the less moving parts, the more reliable it will be.
That design has a weakness right at the top of the engine, if something up there fails it will blow the top off. Engineers don't think the same way mechanics do, they design things to function on a computer, but often times the design isn't practical, its just too complicated.
I have already, within a day, figured out how to make that engine more reliable and less complex. I could even draw it up and make an animated representation exactly the same as they have. I'm lucky enough to see it from both perspectives, as an engineer, and a mechanic.
Instead of running so many extra parts on top of the engine, just make the very bottom of the cylinder barrels telescopic, so the head can stay one single bolted together unit, but the whole thing can move up and down to change the compression. Then run a variable geometry expansion chamber and have flexible hoses run fuel and cooling.
Since it is a two stroke, the crank case transferes air and fuel to the cylinder, so you only need very simple seals on the telescopic part, and they would be easy to change as well. Additionaly, the telescopic system could run off simple rods with hydraulics. The whole thing would be easy to take apart, easy to repair, and be much more reliable.
I'm never against new ideas or technologies, I just hate it when I see engineers get alot of money to do horrible design jobs that could be much simpler and more reliable.

So many times I hear that "they are engineers, they know what they are doing" line.
These kinds of "advances" in engine technology only make it harder for mechanics to repair the engine when it fails, and add useless complication. Most of the time it takes these things several generations before they become even decently reliable, if they do at all.
Like I said, if you take a honda engine without Vtec, and a honda engine with Vtec, the non vtec engine will always be more reliable, less parts to break means lower chances of failure.
Thats why someone has a model T ford that still runs and has never had a rebuild. It's so simple it just doesn't have a big chance of failure. Where newer engines have become so complicated that they have way more parts than they need.
My 1981 XL125s still runs, it's just never failed, but my friend's 2008 baja 125 is falling apart after 1 year.
It's just my opinion as a mechanic that these things just add more problems than it's worth.

A variable compression system will never make an engine more reliable, the more parts you add to something, the more there is to break.
The valve train in a 4-stroke is about as much as you'd want to add. Any more mechanical parts, like variable cam or intake, is just pointless parts that reduce reliability in the long run. If you take a non-Vtec honda engine and compare it to a Vtec engine of comparable size/power. The Vtec system is garanteed to be less reliable. Honda's engines are pretty good as far as reliability goes, but I would still take the simpler design over the Vtec version.
Every two stroke I've ever used short of chainsaws and small engine power tools has had problems, not so much reliability wise, but overheating is a big problem with 2-strokes. Aircooled 4-strokes have a few cycles to oil cool before the next ignition cycle. 2-strokes fire every up stroke, so they generate alot more heat.
I did have one 2-stroke blow the crank seals, and another fragged on a friend, but the fragging was because he didn't know how to shift.
My XL125s can run twice as long, and twice as hard as my friend's yamaha 2-stroke.(can't remember model) Both bikes are from around the same era, aside from his mono-shock, everything looks very similar even.
The yamaha just seems to overheat on the trails, it starts backfiring and missing and we know its time to let it cool down. My 125 has only done that once, after running it slow in low gears to get through a swamp.
That is way too complicated, I feel for the mechanic that has to repair that mess when it comes apart at 7k rpm.
As far as 2-stroke vs. 4-stroke.
I have driven both 4-stroke and 2-stroke bikes, a 4-stroke ATV, and a 2-stroke snowmobile.
The power band on the 2-strokes, both the bike and snowmobile, was nice. But the 4-strokes are much smoother and cleaner, the power delivery is much less violent. I hated the buzz of my friend's 2-stroke bike, it was like a bee right in the ear, and it smoked like a factory.
Both my bikes are 4-stroke, an 81' 125cc dual sport honda, and a 77' 75cc honda mini crosser. Both of them pull like mad when you get on the throttle. And I have totaly out pulled an equivelent 2-stroke on both of them.
My bike is an 81' but this is pretty much how it sounds:
http://www.youtube.com/watch?v=cmLBvVy-j_c
My friend's 125cc yamaha 2-stroke has power, but it just isn't as fast off the line, or as quick at top end.
As for 2-strokes being illegal in canada, they arn't. Every chainsaw or small engine power tool today is 2-stroke.
Lawn mowers are 4-stroke because they are designed to be more eco-friendly, and the average joe usualy killed the 2-stroke ones by thinking they could get away with running it without oil.
A chainsaw isn't expected to be used by the average joe, but by a farmer or trained worker who will know how to take care of it.

LOL, that sounds even less entertaining than my experiance with my 75cc mini crosser up in the ATV tracks near my vacation spot.
I have a bigger bike, but the mini crosser has short gearing and the paths are realy tight in places. There's nothing like hitting the apex of a turn with tree branches flying past your helmet only a foot or less away.

My Dual sport's transmission could be switched to H-pattern just by chopping a hole where the selector lever is on the side of the case and then welding in an appropreately designed selector assembly.
I was actualy considering replacing the drum in a motorcycle trans with an H-pattern shifer for my custom dune buggy project, it looks easy enough, and I could design the required links myself.
If you know how to set up suspension realisticaly, the FZ5 handels far from boat-like.
If I was at my main computer I'd put up my setup, I haven't tuned it in completely yet, but it handels exactly how I would expect an RR configuration car to handel.

Automatics cost less?
Obviously you've never had to replace one. Automatics can and usualy will be alot more expensive to repair.
150k and you replace the clutch that costs $250 including install. And this is being very hard on the clutch to have to replace it at 150k (honda civic with an actual parts cost of $117)
Changing the fluid in an auto isn't realy that expensive, but replacing the auto because it is slipping can be very expensive.
When I worked at a garage, within one year we changed more automatics than we replaced clutches. the cost of replacing the automatic was close to $1000 or sometimes more for a USED one. The cost of replacing the single clutch we replaced that whole year was what I listed above.
Now which do you think is more expensive? Manuals only need replacing if you did something stupid and damaged the transmission. Autos have a nasty habbit of overheating when the fluid gets low. And it gets low alot more often than one would think, alot of people don't know how to take care of an automatic and assume that it takes care of it's self.

I never thaught of it that way, but it does make alot of sense.
Gasses arn't like liquids or solids, they spread out without resistance, but if there is a higher pressure it will always equalize with the lower one.
So yes, it is technicaly the air pushing up, but only because the pressure is lower above the pistons due to the vacuum in the cylinders.
I have edited the first post to correct my error.

I am fairly certain it is the same in ontario, but that doesn't stop people from doing it. It's not as easy to spot as not wearing a seat belt, esspecialy in an automatic.
It is illegal for a reason, if you put yourself in a situation where you can not control the speed of the car with the throttle, and you need to. It is your fault you got into trouble.
I have seen people put the car in neutral on a hill, and something actualy goes wrong where they need to power away. It never ends well.
One person had their car damaged by a run away shopping cart
I laughed my head off for a while after that one.The exhaust shoulden't make more noise unless the engine misses on lift off. Most cars made for the street shoulden't backfire or miss under normal driving, even when engine braking.
Infact when engine braking you will sometimes hear even less noise than expected because most newer vehicles cut or reduce fuel when the throttle closes at high engine speeds.
Once the engine gets past intake and compresses, as long as there is ignition, the expanding exhaust gasses will increase the pressure before the valve opens for the exhaust stroke. So there will be no vacuum in the exhaust system, the exhaust pressure will just drop noticably as it would when ever you close the throttle.
Intake noise may increase, but I doubt it would be noticable.
I think that misconception comes from transports equiped with engine brakes. As I stated, engine brakes are ususaly very loud even when equiped with a muffler.

Not realy, since the vacuum is going to be alot stronger than the air pressure in the case pushing up. The engine is trying to suck in air but is restricted.
Edit: I was wrong about the above, I realized my error after. See below and first post has been edited.
