Re: F1 2001 - Steup discussion.

just a quick hint, if you reduce tire pressure, you tire will "work" more and thus "warm" more...but if you reduce it too much then your car will be "floppy" because of the extra suspension the tire is providing... "Richard S Beckett" <[email hidden]> a �crit dans le message de news: a1ucrg$[email hidden]... x-no-archive: yes From the config file, I found that the optimal tyre temp is 85C. This converts to 185F. So, the way I see it, you need to get a setup that allows you to run the tyres at this temp. Does it really matter how this is achieved? Different driving styles require different setups, but providing all tyres are as close to optimal temp as possible, then surely that's going to result in the fastest setup for that driver? I'm struggling with how tyre temp is affected. I think I just went through this scenario... Going out with a setup, I discovered that the car understeered, so I reduced cornering speed to sompensate. After a few laps, it's apparent that I'm not quick enough, so I go into the pits, and add more wing. This doesn't seem to help, I add more, and things just get worse. In the above scenario, the front tyres aren't getting hot enough, so I get less than optimal grip from the front ones, hence understeer. Upping the front wing, just makes the situation worse. If I actually REDUCE the front wing, initially I get more understeer, but if I carry on pushing the car, the fronts heat up, get to optimum temp, then start delivering loads of grip. I think!? I know that the camber and tyre pressures can be used to get a uniform temp acress each tyre, but I'm finding it hard to get even temps on both sides of the car. So my questrions are... Initially, what makes both tyres on an axle run hotter and cooler? Then when the hardest worked tyre's close to optimum, how do you get the other one to run hotter? I'm really struggling here. I'm assuming that if a tyre has too much grip, then it will run cool, and not enough will make it run hot. I need a list of things to change in the correct order, I think... Would I be right in saying that you start with, say, the default setup. Then, adjust the camber and pressure to get uniform temps across the tyres. Then you need to start playing with suspension to get even temps across an axle. Then adjust downforce to get optimum temp? I'm really struggling here! ;-) R.

I would think, and I'm no setup person, that you want as low an air pressure until the middle temps drop off. Once that happens you have to add a little pressure to balance them out, Correcto??? dave henrie "Richard S Beckett" <[email hidden]> wrote in message news:a1uikr$[email hidden]... x-no-archive: yes But surely, changing the tyre pressure will affect the temp gradient across the tyre? I found by experiment that running it hard would cause the middle to run hotter, and running it soft caused the middle to run cooler. Surely I want the whole tyre to be at the same temp, then change something else to make that temp be optimum? R.

not really... when you put "high" pressure the tire is more inflated in the middlke than on the sides (cause there's the shoulder to block it on the sides...) so you increase the middle temp, but when you "deflate" it it's not because you have less "middle" contact that it warms more on the sides but because the sides "work" more since they are not "blocked" by the "rigidity" of the "high pressure" tire... Problem are with low pressure : High wear cause the tire moves a lot "fuzzy" feeling cause the tire needs a bit of time to "settle", if you have a place where you need to change direction quickly (monaco chicane) you will find it MUCH easier with a "inflated" tire than with a "deflated" tire... as always in setup : good news and bad news, you have to work a compromise...

Having an optimal temperature is just a minor minor detail in a good setup. It also depends on the race or qual....

Try driving faster and dont take note of what the settings are doing just how the car feels FEELS ie take your car to the back road for a spin bet ya you dont think of tyre heat for a while ha ha ha Seriously turn the car to softest setting and go from there as gives you the most flexability ie; body roll which always alows turn in also i dont beleive simulators to be very realistic Grand Turismo 1 for playstation is the best thing on the market for realisism aslond as used with discrestion OK talking real cars email me "Dave Henrie" <[email hidden]> wrote in message news:zWO08.19496$Tq.199221@rwcrnsc54...
