ive been playing with my viper team oreca all day as well as looking around on here for clues on how to make my car faster.this morning all i could get out of her was 222mph.now i just manage 229mph on the big ring.can this car go any faster.ive got nos but iam not using it.the car has been lowerd.the gears ratios played with and also the down force.if any one has a faster viper team oreca any chance you could help.thanks.. :crazy:

I got mine to do over 230 on the max speed test

lower the down force as much as possible, do the ger trick of setting final to 5.000 then setting the auto to 25 then back to 1 then slide the final to spread the gears. What I have noticed is that for the Oreca viper, you lose power the closer you get to red line, the sweet spot is further down the power band. Just keep adjusting your final gear until you no longer gain speed. I use 5 gears most of the time and that seems to be better for me. My top speed of 234.65 was achieved doing that. Hell my oreca can do 214.55 MPH with max down force and that's doing the Nuremburg Ring(sp). It's really fun shooting around the bend just after the bridge and trying to hold on while slowing down enough to make those turns next to the pit entrance. If that was real life they would still be scraping me off the walls.

I did a ring time of 6 mins 27 seconds with 3 spin outs and 1 head on collision with the wall. Now if I were a good driver I would get into the mid 5 minutes times with that car.

Post your speed. My suspension was not tweaked when I ran and it got squirrley at 190+ Mph. It started to shake and it kinda jerked a bit when on the inclined turns.

when you say final spred of gears do you mean the 6th gear.ive just got 212mph out of her.or.am i just stupid.

The final gear

I get 214 with full Down force on the long straight on the ring.

do not touch the individual gears, only play with the final gear.

1st race it normaly by trying to get to red line by the end of the race ie on the back stretch where the finish line is. I had a max of 219MPh

2nd move the final gear only, to widen the gears then race agian you will notice that the car will go a little faster, this is how I figured out the power band on the Oreca is not around the redline.

keep doing that until your car cannot go any faster.

EG I do around 190 in 5th gear, when it switches over to 6th it accelerates like a mofo, you should come out of the 1st turn at 212-214 mph, it's sounds wierd since your at low RPM making you think you are not going that fast but DAM breaking 230 is sweet!!!

I am at work and I will post my gearing later

Sorry was real busy and could not grab my setting,

The following is off the top of my head I will edit this post with the correct setting when I get the change. i am not 100% sure of the following.

👍 =Pretty sure about the setting
👎 =not sure about the setting


Suspension

Tires F:RSS R:RSS

RideHeight F:55 R:55 👍
Spring rate F:15.8 R: 13.5 👎
Dampers(Bound) F:4 R:4 👍
Dampers(rebound) F:5 R:5 👍
Camber F:2.0 R:1.7 👍
Toe F:0 R:0 👍
Stabalizer F:5 R:5 👍

Brakes F:4 R:4 👍

ASM off 👍
TSM 1 👍

Gears: I forget the numbers :guilty:

I do remeber setting my LSD to the follow as I played around for about 2 hours until I got the level of control I thought suited me.

Initial 10 👍
Accel 36 👍
Decel 27 👍

Going beyond 38 accel on LSD creates a very noticeable push effect when trying to blast out of a corner apex. Goin less the 34 and you over steer somewhat. I find 36 to be a good setting though 37 on generally straight tracks like Le Sarthe to be good or 34 on small tight tracks where you are not blasting past 170 MPH.

If you pay attention the car will handle nicely but it can get away from you when you blink especially when trying to manuver while braking at high speeds.

the car handle very well with super softs when testing though it's much harder to handle with racing mediums or harder.

cheers trimen.i got my gtsr up to 234mph to day.felt good.stil slides a little though.
are those settings for the gtsr or the gts 99.thats what iam having probs with now.ive got so many cars iam only just starting to sort them out.again.thanks.

Those are for the Team Oreca GTS-R I am working on the other ones in my spare time. There is still some sliding but not as bad as before. Once you get use to the quirks this car is just plain sweet.
 
Holy 50shot Nitro batman

I rarely use Nitros in my cars

#1 It doesn't seem right
#2 The extra weight sometimes screws the car handeling. If you have nitros remove it and see how much better your car handles.

Slightly off topic but considering you guys obviously like vipers I was wondering what settings you might recommend I use on the 2000 GTSR Concept viper. This is for race use and I running her at stock Hp. Any ideas would be greatly appreciated.

Me, too.

I gathered up this LSD info. I'm starting to get it a little bit:


Limited Slip Differential Guides
___________________________________________

From GTer on the GT By Numbers forum:

Low accel side numbers will allow a driven tire with less traction to spin, usually the inside tire on a tight corner. Low accel side numbers on your LSD might attribute to wearing the rear tires down so quick, especially if one is wearing quicker than the other.

TCS will apply a brake at the wheel to keep it from spinning. It will affect acceleration greatly, depending on how easily the tire spins. With the LSD on full lock for the initial and accel side, as long as one tire has traction, the other tire will not spin.

TCS controls each individual wheel, whereas LSD controls the wheels in relation to each other (this all applies to driven wheels). TCS does not work until a tire starts spinning, and LSD works all the time, but will not control spin unless one tire has traction.

If you have a car with no limited slip, but traction control, and stop it with one tire on ice, and the other on perfectly dry pavement, then hit the throttle, the brake is applied on the tire over the ice, limiting wheelspin. The TCS will slow that wheel down to the point that it rotates within an acceptable percentage for the speed of the vehicle. If the car has an open differential, it may take a while to accelerate.

With LSD, if the setting is at full lock, the tire over ice can spin no faster than the tire over the pavement. Different settings of the initial and accel side will give you different percentages of slip between the tires (accel setting), and at different times (initial setting).

A car with no LSD (open differential) or TCS at all will of course, just sit there, as the tire over the ice just spins and no power is applied to the tire with traction.

I like to use the 1.5 LSD for a car with street tires. With the slicks, I'll usually go to the Full Adj. LSD. If it's a high hp car on street tires, then I'll use the Adj. LSD there as well.

I only run the TCS at about 2 or 3, if I run it at all, on the Grp. C, GT-1, and F1 cars.

There are a few different versions of TCS out there. Some use braking at a particular wheel, some use the power drop (fly-by-wire systems especially), and some manufacturer's call it Traction Control, some call it Stability Management, etc.

Limited Slip Differential Explanation

LSD Initial - Soft to Hard:
Think of this setting as the overall "power" of both the Accel and Decel parts of the unit. It seems to effect the speed at which the Accel and Decel portions engage. When set hard, the car "jumps" out of corners and reacts very quickly, instantly making the adjustments noted above. At a softer setting, it engages smoother (but slower). In fact, when set very low, it's almost like turning the whole system off.

LSD Accel - Soft to Hard:
The softer you set it, the more the tires spin independently of each other as you apply the gas. For example, when turning left and powering out of a corner, the inside tire (the left one in this example) turns slower than the right one (under normal conditions). This is because the right tire has to cover more distance than the left one. If you try to accelerate in this situation the left tire spins as it tries to "catch-up" to the right tire's rotation speed. However if you set the LSD to a harder setting it attempts to keep both tires turning at the same rate. The result is less tire spin which sounds like a good thing (at first thought). However, it's a trade off - you gain more control over the car, but it turns slower (and develops some "push" or understeer) due to the fact that both tires now turn at the same rate. This makes the car want to go in a nice straight line with little tire smoke, but a straight line often leads you into a wall or off the track. I turn the darn thing way down.

LSD Decel - Soft to Hard:
This does the same thing as the accel setting, but it effects the car under braking, of course. As the car slows with this set to hard, both tires slow at the same speed. The advantage is that the car does not spin out, but the direct disadvantage is that now you have to "wait" for both tires to slow down to the correct speed before making the turn. Once again, for my driving style (and the del Sol LM at least) this sucks big time. I want the tires to break loose under braking since this forces the car sideways and then you can cut a sharper angle into the turn. Of course you're on the edge of control and can spin out at any second, but that makes it more fun, I think.
____________________________________________

From "GasMan's Tuning Guide" on Gran Turismo By Numbers ( http://www.granturismobynumbers.com/ubb/Forum30/HTML/000011.html#lsd )

Limited Slip Differentials:
LSD helps the car when pulling away and during cornering. It does this by making sure that the driven wheels both rotate at the same speed. Without an LSD turn in too fast to a tight bend and you will spin the inside wheel through loss of traction, which ultimately scrubs speed and time when you exit the bend. Alternatively the LSD will help the car to corner as well. However by making the near side wheel turn slower than the offside wheel when cornering you will hook the car round to the right meaning that you can enter the right hand bends at a faster speed than without the LSD. Really it's a compromise on the type of circuit your racing at whether it consists of mostly left or right hand bends.

LSD Initial:
This purely dictates how much the values stiffen or loosen the differentials. A higher setting will maximise the biggest acceleration and deceleration values and a lower setting will have the reverse effect.

LSD Acceleration:
A lower setting will mean the wheels spin more independently of each other and a higher value tightens up both wheels which will increase the grip especially when you pull away. Also, by delivering the same amount of power to each driven wheel when pulling away you will help the car to pull off in a straight line and reduce any torque steer (the effect of the car pulling to the left or right under acceleration depending on which of the driven wheels has more power).

LSD Deceleration:
This is the complete opposite of the Acceleration settings and will help the control and turn in of the car under braking. A higher setting will tighten both wheels up delivering the same amount of power to each. The result of a higher setting will be that the car will now have more turn in force and will decrease the chance of spinning. However set the gearbox differential up too tight and on a rear or front drive car you will cause understeer because the back will want to push the front on mid corner.

This is for rear wheel drive (RWD) cars only:

"Initial" setting determines how quickly the lock comes in when power is applied to the axles.

"Acceleration" setting determines the balance of axle lock when power is applied. Too high a setting on the rear will induce oversteer exiting high-speed corners. Too high on the front will induce understeer exiting the same corners.

"Deceleration" setting will ensure both drive axles resist rotation equally. It is most effective in controlling high torque, rear wheel drive cars when entering a tight corner from high speed.

The tranny trick gimps you with the vipers. Do not try to red line it. try my gearing with your setup and see the difference. Vipers lose power the closer they get to redline so setting your gears wider apart so you run flat out about 500-800 rpms from redline seems best. I got to 220+mph with full DF on la sarthe.

edit: how do you keep control of your Oreca with such low LSD settings? With 10 Decel I kept sliding the back end out when braking while turning. I actually spent a few hour fine tuing the LSD to where I have it now. It seemed to be the best balance between agility and stability.

Well, I'll check, but I'm sure it broke 220 on Sarthe II with full DF. Using this setup during my Le Mans car test, I was able to hold off the Sauber and Minolta Toyota for a few laps.

To me, one of the best things about the way it handles is the nice turn-in you get when you trail-brake. For me, the rear end comes out gently and progressively as you turn into the corner with the brakes on, allowing you to brake later.

Its probably just a matter of driving style, and what you like a car to do.

(BTW, I'm starting to wonder about possible differences in the way some cars act in NTSC and PAL versions of the game. I'm NTSC. What are you?)
 
Zardoz

It sure did. I just realized I have my little setup spreadsheet on my computer here at work, and I made note of an A-Spec top speed of 231 MPH on Sarthe II.

Of course, that's with Stage 4 power.
