CPS's

pete55 · 5 Nov 2007, 03:55 (Ref:2059777)

I have been giving the CPS's a bit of thought and have realised that a car coming into the pits first has to give way to a car coming in after him if they are to exit the pits. Why should the first car have to possibly relinquish it's lead for a following car or another car that could take advantage of that first car having to be held. I do wonder how many cars have passed another in the pits because of this. Is this how VESA achieve their positional changes instead of out on the track where it should be happening.
I think i will go lie down now, it's starting to hurt.

It surprises me the amount of times a car is held up by another....I would think the teams would start to realise bringing your car in close to another always has the potential for disaster... Why not wait till the pit lane is a bit clearer...I realise in situations like safety cars etc, you have no choice...

Trouble is the leading car doesn't know if the following cars are coming in. The bit i don't like is that a car coming say 5th in the race could come into the pits after the leader and hold up that leader maybe letting one, two or three cars to pass that car in the pits. Is this the way to do it. To me it seems like a hell of a good reason to get rid of CPS's.

If two cars pit together and enter nose to tail and have similar pit stop times, the car that is pitted closest to the pit entrance will nearly always be the first to exit pit road.

Why?

Because the car leaving the pit box second (ie the car further down the lane) must give way to the car travelling down the lane. You can enter (or leave) the pits right up the backside of the car in front but you can't time your exit from the pit box to emerge just (ie a few inches) in front of a car travelling down pit lane with risking a collision and subsequent drive through penalty.

It amazing to see that so many teams do not seem to understand this.

and yet they still continue to pit at the first opportunity

I haven't been following things that closely this year but at the beginning of the year the CPS's were later in the races but now seem to be back to closer to the start. I thought the later pit stop window was at least a step in the right direction but it appears that has been changed. At the later time at least it got the pit stops out of the high incident zone of the race.

it was changed at winton, not sure why, there was very little info about it

Gid rid of them altogher except for when they need to, like the enduro's. All they do is give an artificial result.

Let the boys race, free up the rules a bit on the track so that they can have a fair dinkum go.

I've thought about this before and came to the same conclusion.

I remember the issue coming up in PanelBeaters and even Crompton was not able to see this. There is a perception that the best place for a team is at pit exit, but unless the pit box closest to pit exit allows you to straight line the exit and gain an advantage that way, the "merge" issue you have raised means it is wrong.

Crompton also incorrectly said in answer to that particular viewers question that it is the same in F1, which is wrong - in F1 the championship team gets the pit box(es) of their choice, which is almost always at pit entry.

Amazing that there can be so many ingenious innovations in V8s and yet they miss the boat completely on some strategy things.

pit entry has no adavatage. you pull in and wait for the stream of cars to go by you before you can pull back in again.

thus the reason the moved them to pit exit

i reckon they need to bring fuel into it, keep it at 1 CPS but have fuel as a factor to mix up the stratagies and make it interesting on track with light cars and heavy ones and have it more mixed (as fuel would mix the stratigies up bit) with who is on older tyres.

I agree this is the case when a line of cars enter the pits.

But when two cars enter the pit nose to tail the car pitted closer to the pit entry will (assuming roughly equal pit stops times) exit first.

With the current rules there is no optimal location in pit lane. It really depends on the circumstances when you make your pit stop.

peckstar · 7 Nov 2007, 07:35 (Ref:2061827)

and there you have it chavez, it all comes down to circumstances.

the smarter team doesnt always pit on lap 6
