What I would love (and yes I know there are reasons why it is not possible or likely) is that when you go into the spare parts shop or even when you change the oil you get to see a real picture of the engine.
 
Okay, here's everyone singing the 787B's praises. I've got just one little niggle. Sorry, but it must be said: To get the thing to turn properly at GVS, I had to take the downforce all the way off.

Anyone know why it wouldn't turn for me?

Because you can't tune for @#$@#%:lol:

Sorry SandStorm I am only joking. I sincerely hope you are laughing. Hopefully you know by now that I am not a vicious person. Well at least not when the moon is not full.

Don't know as I have not driven it much. Would suggest it has a lot of power so you may need to drive it like an FF.

Save your current setup. then try this.

I would put downforce back to stock and suspension back to stock.

Jack the back up at least half the guage ie if the guage has a range of 20mm I would up the back by 10mm. Then max the rear spring rate, bound and rebound. Put front bound to 7 and front reboud to 9.

I have not tried this for this car but would start here. Let me know how you go.

For the hell of it try TCS at stock (I think 5) and ASM off. Then try ASM at 10 just to see.

Hey, no worries, I can't tune for shyte. đź‘Ť

But I'm learning...

Yep, I'll try this.

Min. downforce has enabled me to turn with slightly more ease, I don't have to slow down to like 50km/h to turn anymore.

Please be noted that this is with max power and Super-Slick tyres.
 
Maximum downforce should be helping you turn better you know :odd:

If you accelerate early does it swing the back around ?
Is the car sliding / understeering off the corner or spinning out ?
The 787B is an MR car isn't it ? I would definitely experiment with bound and rebound.

If my previous suggestion does not work try this:

Everything at default.
Set bound and rebound all at 7.
Do 3 laps or try softer tires and do 2 laps.

If car is not getting around the corner then change one of the 4 settings. Bound will affect the first half of the corner. Rebound the second half.

I don't understand these settings but experiment with them. I will learn them one day.

Change front bound up 2 so you have
9 7
7 7 (I think)

If that makes it worse then swap the 9 and 7. If it improves it but you need more then reduce the 7 or experiment with the rebound.

Have you run enough laps to see what your tire wear is doing ?

You could try the extreme toe settings. Also with high downforce the camber settings are always too low.

Provided the problem is oversteer not understeer. Understeer can be induced by an inbalance of downforce towards the back.
 
anybody remember the GT40 race car only 5 gears....

that said thre R390 is my pick and fave in the whole game
try this:
Race a mate in arcade mode on the test course with either of the three cars 787,Gt1 or the R390 (arcade cars of course), the toyota may as well not have 6th gear for all the good it does! the 787 just drives away from the both of them, but on a proper race courseits the R390 that does the dissapearing

Yep, it's understeer. MASSIVE understeer.

Yeah, try it out if you want. That'd help...

I put turbo and Super-Slicks on it.

I tried it last night but was not in the best frame of mind at the time.

I changed a few settings but got nowhere. I can see the understeer you have a problem with.

Thinking about it after I thought the problem is that the front just won't turn almost as if the steering angle is not big enough. Therefore I believe you/we need to work on the front of the car and possibly by applying some toe to the front.

The reason why I wasn't in the best fram of mind was this:

My step kids have gone away for the holidays which means the PS2 is all mine. So I get out my GT3 case and open it. No memory cards. These are the ones with about 70 colourful prize cars.

I look everywhere, think the kids may have done something with them. Then I ask my wife. She says my 2 year old was playing with one of the cases earlier in the day. Great. What has he done with the mem cards. I give up and decide to use my old card. All I could think of doing was test the 787B but still pining for my other mem cards.

In the end I got a brainwave. You will probably laugh at this. I tipped the video recorder up and out of the tape compartment falls 2 mem cards and the PS2 demo disc that has been missing for a few months. No wonder tapes didn't go in there properly.
 
SandStorm, I have some settings for you. My original effort was not beginning with stock settings. I think I had probably tried a Test Course setup in my old game and didn't remember.

But now I won the 787B in my new gamesave so I started from stock.

What I did was used the 787B in one of the easy series. I knew it would be a blowout but was able to test the car. The first race was totally stock so I knew what the car was like. I had not upgraded the turbo or changed the tires but never fear because you will see that I did later.

Here are my settings:

Springrate Front 16.4 Rear 20.0
Ride Height F 70 R 100
Bound F 7 R 10
Rebound F 7 R 10
Camber F 2 R 1
Toe Zero Zero
Stabiliser F 4 R 4
Brakes F 13 R 18 (will discuss below)
LSD Initial 10 Acc 40 Dec 20
Gears Auto 36 (I think)
1st 3.690
2nd 2.308
3rd 1.601
4th 1.180
5th 0.923
Final 3.800
Downforce F 0.74 R 0.91
ASM 10 (merely forgot to change and still haven't)
TCS 5

At stock the car does have understeer. It is an MR car so this is to be expected. On the one hand a strategy is to try to shift weight to the front. This can be done by lowering the front, softening the springs etc but you don't want to go too far. Another strategy is to make the backend lose traction. This is done by raising the backend and stiffening the suspension.

The brake balance depends on how you drive. More front brake will help shift weight but you will need to finish most of your braking early. More rear balance will help swing the back around IF you brake mid turn. This second option can be dangerous but can help. This is clearly the option I have taken and yes I have spun in turns a little.

But all in all in my hands this setup is fairly stable. I don't know if it is quick though as I have not compared it to anything.

Another thing I would say is this car is not a grippy car and is easy on the tires. Sure changing the downforce balance will also change its characteristics but I believe it may need more downforce all around. If you want to change the balance towards the front then increase the front more than the back. But I think you would not be getting the best out of this car by reducing downforce.

I upgraded the turbo and put on superslicks and still kept the same setup. But you MUST take the first lap easy due to the fact the car is easy on the tires and therefore it does take them a while to warm up.

I suggest do 1 race stock ie stock turbo and tires. Then change the setup to this or something similar and do a race. Then apply the upgrades.

Let me know how you go.

Yep...and the Jaguar XK220 Road and Race car also has 5 gears.

The Jaguar looks COOL, but the Mazda handles better. Such is life. :lol: :rolleyes:
