GPL: driving instructor needed

10 posts by 8 people · 28 May 1998 - 04 Jun 1998

O.k., it's time I admit it: I am slow. It's not that I couldn't drive the car around the track. I just can't drive it around quickly. My best lap is 1:12.6, but I usually hover around 1:14. I can do that for several laps in a row without any problem, but that's not the point of driving a racecar, is it? As soon as I risk more, off I go. Maybe some of you constantly-sub-1:10-hotshots could give me some hints? (And if there are some poor souls as slow as I am, you might speak up for support. :) Here's what I do and what I think I should be doing. Please feel free to comment on either column.

Maybe a trip over to The Paddock will help and/or give you some hints.. Check out: http://home.c2i.net/thepaddock and look for the Driving tipses in the archives. As for a quick solution... I would suggest you start using *2nd* gear in turn *8*!!1 Why...? first of all 1st gear is to low and as you go back on the throttle out of the turn - the rear tires loose their grip. The in turn make you lift the throttle and thus reducing you acceleration rate, whilch inturn lead to slower speed going into turn 1... In other words, use 1st gear in turn 8 and you'll ruin the next lap *before* its even begun!!!

I haven't touched the program for awhile, but I know seeing a fast lap helps a lot. Check out http://gpl.gamestats.com for some replays. Choose the FAST LAPS option.

My fast time is 1:07.76, which I've hit twice. It was at one point the fastest reported lap (about three days after the demo was released). Now it's kind of slow :) I think you must lift a lot entering turn 1, but I'm in 4th gear at that point, and hit 5th about halfway through turn 3. T4 does feel really slow. The most important thing to do in this turn is to get a good, fast exit. If you are spinning on the exit, wait a bit longer to get on the gas, or maybe try to "late-apex" the turn a little more. I often have to do a lot of counter-steering at the exit to keep it straight You should never have to lift at all in this turn. The entrance to T6 and T4 both require more steering to be done with the throttle than with the steering wheel. I slow down a lot entering the turn, but once the car is pointed at the apex, I'm on the gas all the way to the exit of T7. I use 2nd gear in T8. -- Pat Dotson IMPACT Motorsports

[BTW, this is in the Repco-Brabham GP >without any helps. 640x480, iP188, 48MB, Monster 1, T2 wheel.] My first comment would be that a faster system would probably help - the more frames you have the smoother you will be able to drive. I'm sure some people will say they can drive 1:06s on a 486SX but even they would be faster/more consistent with a P-MMX or P2 under the hood. High spec Pentiums are not too spendy, so that may be an option. I drive T1 in third, neutral or part throttle. The aim is to not scrub off too much speed by dragging the rear or spinning the wheels, but keep the front pointed such that you get a good line into T2 from the right hand side of the track. The right exit from T1 will set you up in 2, as it's not that difficult a turn. Use the groove and the camber and stay tight into the apex before drifting across for 3. I use third/fourth here. No four wheel drift, as the wheelspin will scrub off vital speed for most people. Totally over to the left, slam on the brakes at or slightly past the billboard. Ease off the brakes as they lock, back of further as you crest the hill then get back on them again hard while aiming for the inside kerb with the RF. A flick of opposite lock if the rear is coming round. Stay tight in to the kerb if racing, or drift slightly wide to get a sharper, and earlier, exit from the turn. Always flat in fifth, regardless of the exit from T4. Turn in early and use the camber to keep you in to the left hand kerb. Slam on the brakes at the second set of dark tyre marks, drop down to third then second on turning in. Hug the apex then punch the car out of the turn and it will understeer across to the apex of the left hander. Accelerate all the way around here, usually apply some opposite lock to catch the rear which breaks loose. Jump on the brakes a second or so into the short downhill straight, and downshift to second. Take first on the way into the apex, then accelerate out using the full width of the road. I generally lock up and spin if I downshift to first under braking for this turn, which may be to do with too much locking effect from the diff with the setup or perhaps (more likely) the timing of my downshifts :-) Probably watching someone is best - try looking at some demos from in-car view to get the braking points and lines. It doesn't show throttle or gas positions, but you should get a good idea. Cheers! John

I take T1 in fourth gear and just lift a fraction on the entry to the corner, fourth gear is much more stable than 3rd gear, you are more likely to spin in 3rd gear if you get it wrong? T2 is taken in fourth gear and once again I lift for a split second just before the apex, then power out of the corner just missing the hay bales on the right. I usually change up to 5th just as I hit the apex, before the end of the arnco on the left, then power down to the first braking area. NB:- the key to these first three corners are to keep the revs as high as possible, to carry as much speed as possible through the corners, and to be as smooth as possible. Sounds easy I know, but..... I only break down to 4th gear as once again it is a lot smoother through the long right hander than 3rd gear would be, and you can carry more speed into and through the corner, thus giving you greater exit speed? I brake just as I *pass* the sign on the left, not before it! Try to brake as smoothly as possible, I power out of this corner and change up to 5th just as the arnco barrier ends on the left. I do tend to lock the wheels on entry to this corner, but I personally do not think that affects the time too much? (I've seen a couple of the sub 1:07 guys locking wheels consistently and it doesn't seem to affect them too much either!) 8-) You can also lose time by trying too hard to not lock the wheels? just concentrate on getting down to the right entry speed for the corner, and if you lock you wheels.....so what? You *never* lift at this corner, it doesn't matter how fast you are going, it can *always* be taken flat out, easily! Just try and anticipate the corner and turn in smoothly. Once again only change down to 4th gear *not* 3rd! 3rd gear is much too twitchy, the slightest mistake and you are off, 4th gear is much more stable and therefore forgiving, mainly due to the slightly lower revs at 4th than you would have in 3rd? I brake just *before* the end of the arnco on the right, and try to be as smooth as possible under braking, and carry as much speed as possible into and through the corner, powering out the other side, still in 4th gear. T7 I take still in fourth gear, I brake immediately after the apex, and brake down to second gear *not* first gear! first gear should only ever be used in any race car at the start of a race, after that it should not be used at all, as it is far too easy to spin the wheels and fly off the track. once again try to be smooth and carry speed hru the corner, powering out of the final T8 and up through the gears, usually in 4th by the time I pass the line, ready to lift and take the first corner. I really feel the *key* to fast times in GPL (as in every other sim?) is *smoothness*. You appear to underestimate how fast the car can be taken into and through the corners? Try to go just that little bit faster and you will be surprised how the car does manage to stay on the right line, it just takes commitment to stamp on the peddle, point it in the right direction, and hope it sticks to the track! If you have done it right, it will!!!! You should also note, that the corners are crucial. time is won or lost at the curly bits of the track, not the straight bits! If you can master good cornering technique you are half way there? Try to brake a bit later (smoothly) and turn the car in a bit too much, then dab the throttle and the car will swing around as the weight transfers and as you hit the apex the car should now be pointing roughly in the right direction, and you can plant the throttle on the exit cos a) you are carrying a bit more speed cos you braked later and, b) you used the *pendulum* effect on entry to the corner to finish off pointing the right way. It also helps to watch just how the fst guys do it? download a few fast laps, and watch, and watch, and learn, and watch again, and even take notes if you have to, but you can learn a lot from these replays. One last tip if you want really fast times.....Use the Lotus, it's easily the quickest car of the three (but a bit harder to master?) 8-) Hope the info helps..... BTW: My best at GPL is *only* 1:09:95 so I am by no means one of the fastest guys out here? *Peter* 8-)
Thanks for all the suggestions. I planned to return with a significantly improved lap time, but it seems I need more practice on the new line... -- Wolfgang Preiss \ E-mail copies of replies to this posting are welcome. Uni des Saarlands \ and U.S. law. You have been warned.
Supplemental: 1:10.08! Not a bad improvement from 1:12.60, is it? Needless to say I spent several hours trying to break the 1:10 treshold, but it's enough for today... :) The credit for this improvement goes to: - you guys. Thanks for the suggestions! - approx. 250 laps of training (today, that is) - Colin Chapman. The Lotus is much faster than the Brabham. And easier to drive quickly, actually. You just have to keep an eye on the rev counter: as long as the instrument is below "9 o'clock", everything is soft and easy. But above... -- Wolfgang Preiss \ E-mail copies of replies to this posting are welcome. Uni des Saarlands \ and U.S. law. You have been warned.
I am not sure whether I am impressed with the content of this thread or the quality of the physics engine of GPL. Actually it's both, but which came first? The chicken or the egg? There have been some great tips in r.a.s. over the years on how to tackle a track. But this has to be the first thread that I've followed that sounds as if we are talking about REAL race cars and REAL tracks. I'm sure that if this thread were seen outside of the "simulation" community, the readers would be convinced we were talking about "real life" situations. Thanks Papyrus for upping the ante! And thanks to the r.a.s. guys for sharing their insights! -- **************************** Michael E.

uh oh , we have to end this thread soon. I think it might start to get constructive :-)
