Man some people talk some shit.

Honda make amazing n/a motors with fantastic power for their size.

Maybe they do, but Civic's are still slow. An EX runs the 1/4 at what, 17 seconds? An Si runs at 16?? That's slow, at least where I come from. Hell, my V6 Camaro with iron block, iron heads, runs a 15.2.... My little Scirocco runs a 15.4!!! It's got an iron block, only 8 valves, and mechanical fuel injection! That's old technology there folks.

Quote from alex_nz :

It cracks me up when people hassle a b16a motor making over 110kw at the wheels. Thats 110kw at the wheels from a 1600 with I/H/E... not bad power per ltr....

Again, the car could make a million hp, but in the real world, how fast is it? I agree with you to a point, I love anything that makes good power and has some engineering appeal, and I guess Honda's are novel in that respect, but this whole scene where everyone thinks they are the new sport car is so messed up, when you have $1000 in mods to a Civic and they are running like 15.8's.....

Quote from Becky Rose :

The rest of your post ridicules the Mac and makes you sound all knowledgeable and educated, then you said this... You surely meant it's similar to Linux because Linux is based on Unix, which is what sits underneath MacOSX.

Yeah, sort of implied, actually. :P Most of my co-workers refer to any Unix/Linux port as Linux, be it BSD or Slax or whatever since on the outside they all look pretty much the same. But anyway- I'll admit that I dont have a lot of practical knowledge of *ux, I "administer" a couple of mail servers but that's just simple stuff like updating spamfilters and whatnot.

Seriously, if you are interested in any sort of PC gaming whatsoever, you dont buy a mac. Plain and simple. Very few of the mainstream gaming titles are released on macs, and why should LFS be any different. I have been working in the computer field for nearly 10 years now, have a bachelors in Computer Science and the only thing I have learned about macs is that they are practically worthless. Not to sound harsh, but there is a reason why out of the 350 or so PC's and servers in the dozen or so businesses that I service every week, NONE of them are macs. Oh and the best thing about OSX is that it's mostly Linux.

Quote from Forbin :

Does it matter? Only reason I see for giving internal engine specs is as a justification for a particular power/torque curve.

I wouldnt think so. Compare a VW 1.8 8-valve and a 16-valve. Both are the same bore and stroke. The 16-valve makes more power in stock form, but driving a similar car, take a Scirocco for example, with both engines back to back there is a noticable difference- but like you said it is all about the powerband and the power delivery of each engine. The 8-valve has a very flat, broad torque curve, with a little extra bump right around 5500 rpms. The 16-valve is a gradual increase in power delivery until about 5000 when it starts pulling hard until 7000 rpms. Both engines are easy to model in LFSTweak and feel accurate in the Gti. LFS's engine system is quite accurate in most accounts, if you get the hp and torque in the right rpm range, it should feel pretty darn close to the real engine, nomatter how many valves it has.

Quote from tristancliffe :

Corvette. Apparently the latest corvette was rumoured to be able to do corners, but alas it was just hype...

Hmm, a lot of the design and testing on the C6 was done by some German engineers in ... er.. GERMANY. :P The C6 Z06 ran a lap at Nurburgring in 7:42.99. That's pretty damn fast. If a car cant handle, there is no way it can do a lap at the 'ring that quick.

I'll be the first to admit that most American cars are crap- I've owned two of them. My 20 year old Scirocco with blown shocks and Wal-Mart tires could out-handle my 00 Camaro with ease. There are always some exceptions to the rule though, the new Solstice and C6 being two of them.

Yeah, I think that is part of LFS tyre modeling that is incorrect, as the higher the sidewall is in LFS, the stiffer the tyre is, so you can have like 10 psi of air but they are rock hard. In real life, it is quite the opposite. :P

1970 Chevelle SS 454

One of the highest powered production cars in the muscle-car era, factory rated at a very conservative 450 hp and 500 ft-lbs of torqe. This version has the M22 "rock crusher" close ratio 4-speed with 3.73 rear-end gear. Capable of 13.7 1/4 mile time. From what I could gather, most factory 454's in the Chevelle in 1970 made at least 470 at the wheels, which probably means they made something close to 500 crank. They had an aggressive solid-lifter cam, 11.4:1 compression and a holly 800 cfm carb which was good for about 5 mpg. It's a heavy beast with relatively narrow tires, and road_normal should feel pretty close to bias-ply tires. One unique thing about the Chevelle, is that it had a 4-link "live" rear-axle with coil springs that made for decent handling despite it's heavy weight. It did have front disc-brakes but they werent quite up to the task of stopping a 3700-lbs car with 450 hp so give yourself plenty of braking room!

Have fun, I dare you to take it on an auto-x course.

Replace "." with "," if need be.


Brendan

Here's my shot at the VW Beetle Salzburg Rally circa~ 1972. Engine is as close as I can get, gears are spot on. As far as I know, the only real changes they made between tarmac and gravel is swaybar and tyre. Road_normal should be pretty close to the bias-ply tyre they had back then. Gearing only allows for about 100mph top speed, so it's not good for big long tracks and there really isnt a good track for it in LFS yet, but auto-x and Fern Bay club are fun. This is a U.S. spec keyboard so replace "." with "," if need be.

Have fun!

Brendan

Yeah, LFS has a big trouble with lightweight cars, there is NO grip whatsoever, even with much bigger tires. One thing you can do is if you make a really lightweight car that just flies into outer space, you can add driver/fuel and max the fuel, usually it's enough to keep the car grounded. :P When I was making a car for the drag competition, I was starting with a lightweight car and was getting nowhere. Eventually I used a really heavy car and made some progress. Strange behaviour when you start making things "outside the box" in LFS.

Brendan

Er anyway, here is a better soundclip of a VW R32 VR6, stock exhaust:
http://www.houseofthud.com/car-av/r32-firstgear-launch1.mp3

It's better at hearing the distinct sound of the VR, kind of a burbly purring sort of sound, very unique.

Brendan

Hmm, says at the end of the video it was twin 3" exhaust? Oh well. That VR6 GTI made 640 hp with a single turbo and nearly half the displacement, in a car that weighs nearly 1000 lbs less. Hey, I love american V8's as much as the next guy, but sometimes there are better ways to move a car down the road.

Brendan

Quote from sil3ntwar :

there is no mention of torque and the horsepower only says between 600 and 900 and it gives no rpm values so it doesnt comply with rules 3 and 4...

Actually there is, under dyno tests. Also the "media" section has video and dyno testing with real numbers.

Brendan

For those that dont know: http://www.eiptuning.com/eip/videoeipgolfvr6dyno.mpg

This one has a turbo, but oh well, you get the idea. I knew the guy that is leaning in the driver's side window btw, he said the car was crazy. You could be driving down the highway at 75 in 5th gear and floor it and the front tires would light up.
:jawdrop:

Brendan

Oops, yea, it's GT class with slicks. Here's a link, under the "projects" section on the left. http://www.audituning.com/english/main.asp

I've actually got it around 1:12: a few times in practice but didnt have a replay.

Brendan

Here we go! 1:14:72. The car? Dhalback racing's RS1 VW Golf. AWD, 900 hp. I have not really done a lot of hotlapping with it as it took me forever to set the car up, but I think it's pretty good now.


Brendan

Hmm, my Camaro is a V6, so it's a bit lighter than most, but it still handles like crap. :P On the other hand, my girlfriend's Civic is slow as balls, (yes, with VTec) and also handles like crap. My VW could blow them both away on a road course, and it's damn near as fast as my Camaro in a straight line. But hey, I'm selling my Camaro p.o.s., and my girlfriend's Civic has 385,000 miles and still gets her 35 mpg and that's all she cares about. Although my VW is 22 years old with original engine, it gets me 40 mpg. I had a redneck in a beat up 5.0 mustang scratching his head the other day, just couldnt get past me from stoplight to stoplight. And I'm just starting on the crazyness with my VW- it will soon have roughly 250 ft-lbs of torque and get 50 mpg. :banana:

Gonna be really tricky without downforce! Somehow I dont think a crazy 1000 hp car is going to win this one.

Brendan

Heh, thanks much, I am having a lot of fun with this little program. I noticed a bug, not so much with LFSTweak but with LFS itself, when you make a bigger tyre, it really makes no difference what the tyre pressure is and the tyres are too hard. Like, if you are making a RWD drag car, with like 440-50-15 tyres in the rear, you can drop the pressure all the way down but the tyres will not deflect. I actually found out when you are dealing with huge tyres, if you blow out both of the rears first, you get more contact patch and more grip. :P

Looking forward to having downforce in the next release.

Brendan

How about an MRT with bigger, fatter dirt tires and a bunch more suspension travel? Would be a lot of fun on a bumpy dirt track, or better yet, a small dirt oval.

Brendan

That, and if you wash through a turn and hit the marker cone and both pointer cones, you get charged 6 seconds.

Brendan

Ok, my main problem with the RB4 is that it's a big, heavy, underpowered pig. Even a lighter, higher powered version would almost be too big (ie. wheelbase too long) for an effective rally car. I've put rallyx tires on the UFR and it's near perfect for rally, much like the MG super1600 in RBR. If anything, an AWD, 300 hp XFG would make a dandy rally car. But, all of this is moot until we get some proper rally tracks, as it stands right now on all avaliable rally tracks, the cars performance on the tarmac section is more important than the dirt stuff anyway, which is why the RB4 isnt the fastest rallyx car out there right now. :P Keep the RB4, as it does handle well and has a high amount of grip. It's strong points would be auto-cross or a proper rally-cross type event, where traction out of tight turns is more important than speed.

Brendan

Quote from Hyperactive :

The turbo in RA is barely noticeable for me. It feels almost NA...

Yeah, I get that feeling with nearly every turbo car in LFS. If anyone has played with Netkar, drive the Supra- it has some of the best turbo modeling I have ever seen in a sim. More importantly with the way boost builds and the way the behaviour of the car changes when the boost comes up. I've taken a ride in a street Supra (not anything like the GTR Supra in NetKar) that had an upgraded single turbo, boost maxed at 20 lbs at probably 2600 rpm and held there all the way to redline. Car was pretty fast too. I've also driven many 1.8T VW's (I used to work for VW) some stock, some chipped, and some with upgraded turbos, and the boost responce was nearly the same in all of them, although the upgraded turbo car was a bit more "laggy" down low, it still had nice mid torque but when the turbo came into full song there was that "kick in the back" feeling that hit much harder than the stock turbos did.

I would imagine turbo modeling in a sim would be a very difficult thing to do, especially on cars that are not really based on real-life counterparts with real-world data to compare them to. The exception of the RAC, and from what I have read the engine in that car is nearly identical to the Saab "Viggen" engine which had very quick turbo responce. So who knows.

Brendan

Got it to work, by doing the above, still had my original lfs S2 download so I extracted it to a "LFSTweak" directory, although I used all of my unlocks so I just have demo cars for a while. :P

I do have one suggestion- PLEASE do something about the interface, it is downright maddening to use!! With the cusors jumping around and having a dialog box pop up telling you you cant have a null value when all you did was clear out what was there so you can type stuff in. Otherwise, having a lot of fun with it, made an Audi-S1 Quattro, inline 5 turbo with 500 hp, very similar to the rally car and even sounds similar! What a beast to drive, too! Now, if only we could change exhaust raspyness like in LFSTweak...

Shows some great potential.

Quote from Gunn :

These are precisely the types of places where you must be cautious approaching the braking zone. If you hit him, it's your fault, not his. He can brake as early as he likes, drive as slow as he likes, take an inefficient line, all three (keeping within the rules of course). Unless he is under blue flag conditions he doesn't need to worry about how fast the car behind him is, he can drive his own race.

Well perhaps I didnt explain myself very well. I had been following this guy for about 4 laps, and I knew that my tires were better off than his, and I think he knew it as well. At that point, I knew where his braking points were, and he deliberately slammed on the brakes full lock, and when I hit him, he took off while I spun into the wall. The time that it happened in BL on the chicane, it was another prick who kept saying he was the best racer in the world, well, I was all over his rear bumper for two laps, and he slams on the brakes on the last lap in the chicane, (a place where he hadnt hit the brakes the two laps prior, we were racing GTI's) and again, he goes flying ahead, I spin and crash.

It's pretty obvious when things like this happen. I know when there are new people on the track and sometimes they get in the way- it happens, and I've done it before too. It just bugs me that someone has to exploit a part of the game just so they dont come in 2nd place. I guess better damage modeling will help this out a little, as in a real race, if car A going 65 mph hits the back of car B who is going 20 mph (and braking hard) both cars are pretty much screwed. :P

Brendan

I know it would be hard to write in to the game, but I've fallen victim several times to "brake checking", where I would be following someone for a few laps, and suddenly, they slam on their brakes full lock and I smack in the back of them, propeling them ahead and causing me to spin. Most of the time it has happened in key places, like the chicane in BL or the 90-degree turn 3 at SO town. I suppose when damage modeling gets a little better, and doing something like this actually hurt the car in front more, people will stop doing it, but it really sucks when you know you are faster and some idiot cant handle coming in 2nd instead of 1st.
