FITT RUF Challenge

[DolHaus]

Just letting them know in advance what they are in for. I always thought this is how Porches were supposed to look when hooning around on the open track..

An old porsche over-steering is usually what you see before it disappears arse first into the nearest ditch
(followed by some guy in golf attire getting out and berating his assistant on the phone)

 

[Otaliema]

And here I thought the S7 was the only understeering MR dog in the game....

PD weren't giving out much love when they programmed these RUF cars. This is why we have to make them great, or just fun to drive in my case.

 

[Otaliema]

I just PD would stop adding content and fix and repair whats present.

If you want, I can give you the specs for 996 GT3 Cup LSD ( lock%, including preload ), springs ( too high though 240Nmm and 260Nmm if not mistaken )and gear ratios ( which I used ), the car tops out at 255-260kmh at Nurb GP/F.

I do want to see it, thanks for the sharing

13.5 The ramp angle of the differential lock is 32 degrees ± 17’ (acceleration) and 45 degrees ± 17’
(deceleration). The ramp angles are determined relative to the rotary axis (Appendix 3). The
resulting locking ratio in combination with the friction discs is 40/60%. The minimum locking
torque of the differential is reached whenever the torque value is 80 Nm – measured at the
gearbox driveshaft output flange. Falling short of the minimum value is not permissible at any
time during the event. The maximum locking torque of the differential is reached whenever the
torque value is 180 Nm – measured at the gearbox driveshaft output flange. Exceeding the
maximum value is not permissible at any time during the event.


I used 3.7 final to avoid bouncing rev limiter on the main straight.

How can you convert the ramp angle in degrees in the number ingame ?

 

[Ridox2JZGTE]

You can't Use the lock ratio, 60% on accel and 40% on braking/coast.

 

[Lionheart2113]

You can't Use the lock ratio, 60% on accel and 40% on braking/coast.

I've seen you mention those %'s before and have always intended to ask... Does that mean...
Accel @ 60% = 60% of the available slider?
Decel is 40% of the available slider?

Roughly, yes, but often I made slight adjustment to suit the car/tires. So for example, my RGT that I tested at Nurb GP/F had 11 initial, 36 accel and 24 braking. Works well for the tires and setup.

 

[steve nfs]

This is my final laptimes for this most undrivable RR car. I just 'force' to learn to control the very sensitive throttle/rpm of this beast to go fast. 1: 29 can be a consistent lap if you 'love' her.

 

[ugabugaz]

Damn that's an impressive time for the BTR ! I'm gonna have to give your car a go. Only .392 off my best in the Bird.

I'm close on 2 of those. Trying to figure out why I'm so far away on the 3rd. It's gotta be down to the setup portion.👍

RUF BTR '
-
The Ruf BTR (Gruppe B Turbo RUF) is a sportscar built by Ruf Automobile of Germany starting 1983, based on the classic 1978-1989 Porsche 911, available in a narrow 911 or optional in a wide Turbo body configuration (the drag difference causing more than 12.5 mph (20 km/h) difference in top speed). It was powered by a 3.4 liter, flat-6 turbocharged engine, producing 480 N·m (350 lbf·ft) @ 4800 and 374 bhp (279 kW) @ 6000 rpm. It was coupled to a five-speed transmission, a six-speed transmission became available 1988 by request.

The Ruf BTR was the first car with Ruf VIN, construction of each vehicle began at the bare chassis level. About 20-30 were built this way, probably even more were converted from customer cars.

In 1984 a Ruf BTR won the "World's Fastest Cars" contest of the American car magazine Road & Track with a 10 mph (16 km/h) lead and also dominated the acceleration tests. It did 0-60 mph (97 km/h) in 4.7s, 0-100 mph (161 km/h) in 10.4s, 1⁄4 mile (402 m) in 13.3s reaching 110 mph (177 km/h) and managed a top speed of 186.2 mph (300 km/h). [2]

In Auto, Motor und Sport 22/1984 a Ruf BTR set a new 0-100 km/h acceleration record for production cars tested by the magazine. It did 0-100 km/h (62.1 mph) in 4.6 seconds, 0-200 km/h (124.3 mph) in 15.5 seconds and 0-1,000 m (0.62 mi) in 23.0 seconds.[

Looks good to me. Tune is good to go. Nice choice of colour as well. I love that shade of blue on the RUFs.

Edit: You need to include weight reduction stage 3 in your notes to reach 550PP.

 

[coryclifford]

191 kilos!?

 

[xande1959]

191 Kg yes

 

[shaunm80]

@xande1959 I edited my above post. You need to add in Weight Reduction to your tune information to reach 550PP when building your tune.

 

[ugabugaz]

Drove my RGT again today and decided I didn't like it at all. Changed a few things around and it seems better now. Still think it's missing a little something even though the laptimes are pretty good.

 

[shaunm80]

@Otaliema, You can put me down for testing in both of your classes now. I will try and find the time to do them all when testing begins.

 

[Otaliema]

added ya to super sport We have one posted tune for the class already feel free to take it out.

 

[Otaliema]

choices choices, got the car stable, but needs load of throttle control due to tight gears, I can make it into a 4 gear and aleveiate that some but loose speed on the short straights but the overall laps are more consistant and fairly close to the tighter gears....

 

[Motor City Hami]

I was testing last night and the Yellow Bird was just sliding around, both front and rear. It was pretty balanced, but had no lateral grip. What to do next, I mean, it was balanced, so what to change to simply get more grip? I thought about testing soft vs. hard springs. I thought about testing soft vs. hard sway bars.

Then I opened the suspension settings and noticed that camber was turned on. 1.0 front and 1.0 rear. How did that happen? I turned camber to the full off position 0.0/0.0 and problem fixed. It is good to see that PD has left camber alone since fixing it in update version 1.09.

PD aint done squat to the game physics after 1.09 and 0 camber cars from 1.02 on still work just fine. I know because I am still getting great results from 1.03 cars from a two years ago.
Can't wait to see what you have done with the bird. 👍

I find the same thing happens with traction control from time to time, turn it off when you buy the car then the next time you take it to the track its set itself back to 5.
Sometimes I put a bit of camber (below 0.5, equal F/R) on tricky cars so I can try and find maximum grip/ideal balance under less than ideal conditions and then drop the camber off it. Good way of finding the full potential of various settings, helps avoid the "Change one big thing, get result = That'll do" trap

 

[steve nfs]

Camber not fully heal. Just treat it as alcohol, don't over done it.

 

[ugabugaz]

Both my tunes are running no camber, I don't trust PD...If this was GT5 my YB would probably have lots of rear camber (2.5+).

 

[DolHaus]

Camber has its uses, its just unfortunate that improving grip isn't one of them

 

[Otaliema]

Camber not fully heal. Just treat it as alcohol, don't over done it.

That's the best advice on camber I've heard for GT6

 

[coryclifford]

That's the best advice on camber I've geared for GT6

What? Do you not reread what you write?

Camber to zero is always the first thing I do.
