Leon, your sig is from La Mans, right? My second favorite racing movie, guess which one is my first.

Yes ;)

But Papyrus didn't do any serious research about the P 83 and P 115 H 16. The car wasn 't that hard to handle, and its potential was superior. When Stewart led at Spa, it is not because of his talent, but because the car had potential on fast tracks. In GPL, go to Spa67, take two drivers with the same speed, put one on the Eagle / Lotus/ Honda/ Ferrari, and the other on the BRM, and he will be beaten fair and square.

The car suffered more of engine oil pressure as retirement causes, but with more reliabilty, they wld have finished in the championship points more often.

Maybe the best proof to what you say are Jim Clark's results with the Lotus 43. Even though he was almost always forced to retire he was actually competitive with the H16.
But who knows? After all, reliability is an important part of a car performance. So, a car with poor reliability is ipso facto a poor performing car, no matter it's top speed or cornering ability. Shame, because it actually sound terrific and it is a unique engine in Grand Prix history.

I always seem to drive the Brabham BT11 in the 1965 mod, and the BT23 in the F2 mod.

Some possibly helpful advice about learning Grand Prix Legends


1. Start collecting and installing tracks! There are 600-plus tracks. So start finding tracks you like to drive. Do not wait. Do not set some artificial proficiency challenge that keeps you from enjoying as many tracks as possible as soon as possible. They are all works of art.

2. Practice is more important than learning. Mistakes are more valuable than good advice or theory. The penalty for failure is Shift-R, so go for it. The sooner the better. You do not find the racer's edge or the car's potential, (max lateral load), by driving slow. Ai pretty much follow the racing line...follow them while searching for tracks you like to drive.

3. Driving any sim without display calibration is like playing a guitar that is out of tune. Default car setups were not created in sync with any other display other than the one on which they were created. And there is no assurance that display was calibrated.
It is rare coincidence if any third-party setup is appropriate to the driver and the rig. Otherwise, using an imported setup requires its adaptation to both, which is the same as "making your own setups."

4. Setup theory is all about adjusting for understeer and oversteer until the driver finds the car responding to inputs as intended and expected. The front and rear anti-roll bars alone compensate for either so are the only tweaking necessary once at the track. To adjust for a given setup, incrementally raise one and reduce the other.

Too much oversteer - increase front and reduce rear. Too much understeer - increase rear and reduce front.
Think the big secret of setups is that's all there is to it.

5. Okay,, anti-roll bars are not all there is to know about setups. One more important clue is that some setup variables control the rate of change and others control the extent. Shocks and diff control the speed of suspension changes. Springs, bars, toe, bump stops, ride height, and camber control extent.


:D

I did a little video of the '55 mod to show my friends what I do and how freaking awesome it is, the non sim racers still don't get it, LOL!

John-The setup that most helped me in the past as been Tyre pressure and spring rate.You talk about following the AI driving line.

As well as Tyre warm up is there a grip advantage by following the AI driving line.Is it just a driving line advantage?Or if you go off line does grip reduce? I know the Tyre compounds are a lot different today than from yesteryear(IE slicks) and regarding rubber down ?

Nice video ti2blegrr your now voted the new mod promotional video guy :D :D

To finish 'Hey isn't it fricking great that since the 55 mod as been done,loads of new users and members have come on board here and gpl itself.

55 Mod team you should be proud. Thank you all again :punk:

ti2blegrr,
Thanks.

TP - following the Ai is to help learn the driving line without worrying about it.

For tire temp science visit Lee's Motorworks.

For quick analysis and hints:
Tire Temp Diagnostics

The Tire Temp Utility

Spring theory: soften until springs bottom out or car gets "wallowy," then stiffen.
Alternate theory: stiffen springs until car's tires skip across turn, then soften.

GPL default tracks (and possibly many add-ons) model road camber - the center is slightly higher than the edges;  crossing over the crown, especially in curves, will affect grip/handling.  So running wide in medium to high speed turns almost guarantees some off-road action.

Ai are not experts at the racing line and their speed is artificially governed by track section spreadsheet iirc.
My suggestion they be followed was simply for convenience and safety while driving around touring a track.
"The racing line" is something different.

Grand Prix Legends does not model rubbering in except with the graphic of the groove shadowing on a track. It does not effect grip, which is the same everywhere for a given track surface. Changes in track camber and the car's trajectory thru a turn effect its behavior and grip/traction. The groove file is intended to indicate the racing line.

JMHOs.

Forgot to note the Primary Directive which is...

Be Your Own Expert

Trust no one short story...there was once a "guru" that published a big ramble about theory and practice. It was there for a few years and everyone accepted it as worthwhile and credible. But turns out, while some found benefit, critical parts and the claims the guru made were completely wrong. It is not the only example of guru error with respect to Grand Prix Legends.

You guys helped a lot, I ran some laps yesterday at Monza in the F2 Copper T46 standard chassis until life called me away, I'm putting in close to 60 hours a week at work :( Changing the stearing ratio was the only set up change I made, I went to 17:1 with the black Momo.

I probably used to much brake just trying to get a feel for the car and try to keep it off the wall. I think I'll be getting good lap times soon. :)

1 1:56.34 2 1:56.14 3 1:48.24 4 1:46.16 5 1:44.18 6 1:42.90 7 1:44.26 8 1:43.63


I can not thank you guys enough in helping making this sim enjoyable!

Almost, huh?
If I wasn't so humble I'd feel insulted.
:P

Just a guy with spastic bighead syndrome.
Comes and goes.
Sometimes can't help it especially when it comes to Grand Prix Legends.
In which case I always defer to the actual gurus di GPL.
