It would be interesting to see actual lap time improvements as different mods were added to your S2000. Anyone willing to share?

 

It all depends on the track and the car.

Refer to s2k challenge for a rough idea of how each mod affects lap times at Buttonwillow.

 

Driver is the most crucial factor, so BW lap times between classes do not say much.

I´m asking same driver, same track, how many seconds did a particular mod cut you. Although I guess not many keep track of this.

 

S2k challenge podium drivers till turn in lap after lap with minimal variance, usually less than 0.5 seconds through the session barring traffic.

Are you at that level of driving? Are you driving at the same tracks? If not, none of this matters.

The general idea behind our point system is 1 point = 1 second at buttonwillow. All participants are very aware that the scale completely changes as we go to different tracks.

I checked S2k challenge results before posting my previous reply, and I saw a huge variance of lap times in the same classes - mostly looking and stock & street (10 to 20 seconds gap between 1st and last, and around 5 secs for top 3). This was to be expected, since driver levels are not taken into account for the points system, and of course there´s a big difference between drivers.

There´s also an infinity of additional factors that are impossible to account for (each car´s exact weight, alignment, tyre temps, aero effectiveness, engine output, etc.). And how different mods affect lap times at each track.

However, I still believe it could be a valuable reference to read a "lap time evolution" of different drivers and their cars - something I don´t believe I will be reading judging by the overwhelming response

 

It would be something like this:

1. Driver
2. Weight
3. Tires
4. Suspension
4. Aero
5. Power

 

its hard to say since I've modified the car its given me more confidence to push it and thats made me faster

if I stepped back into a stock car I could get it round a lot faster than before

springs and lowerring it helps a lot.. the wing seems to help a lot although I'd learn to drive it without one first


I would say get a datalogger first off so you at least have some point of referance

 

If I were to list importance of those categories, I'd say:

1. Driver
2. Weight
3. Aero
4. Power
5. Tires
6. Suspension

I'm assuming tires just means difference between R-comps and top street tires, since were talking about tracking here. Also making the assumption that we are talking about a set a new tires. If not, I'd bump tires up to #2 if it were the difference between a heat cycled old set of S02's versus a new set of shaved NT-01s.

 

i think you guys are missing the op's intent / question: he wants to quantify value of a specific mod. and i think that is a good thing to know. think dyno results in track time instead of hp, for the purpose of testing compoennts. did i get that right op?

obviously skill is important in going faster. that's not the point of his thread (if i read correctly.)

so, as for the list posted:

1. Driver <- irrelevant
2. Weight <- okay... good start. so, how many lbs = how much time?
3. Aero <- again, which wing = how much time?
4. Power etc.....
5. Tires
6. Suspension

now, i realize the question is hard to answer since as pointed out, different things matter more on different tracks, and are also dependent on a driver's skill and somewhat his driving style. but since psychoazn insists that there is little variance between the top drivers, then this lends even more to the validity of this subject--that a mod's worth can indeed be quanitfied in a valid way.

not sure if the question can really be answered due to all the variables, but at least address the question.
