AMS2 Super V8 @ Cascavel, Thursday 6th April

[GeekyDeaks]

Super fun racing in the Super V8. Some good battles out there but mostly it's a personal battle just keeping the car on track

You certainly proved to be the master of these beasts! Had good fun trying to keep up with you when I could keep it pointing the right way

Have fun at the GP!

Hi Scott, thanks a lot for organizing this. The racing was fun. I also enjoyed the banter over Discord, would have loved to participate more, but the driving is already maxing out my full intellectual capacities. . Supercars were fun on softs, on the hards, as stated before by the others, for me it was more a race to stay on track, rather than racing the rest of the field. In this regard, I liked the Caterham better on Tuesday. Have you raced the 90s DTMs before in this series of events? Happy Easter and hope to see you all again next week. Cheers, Chris

We have raced them a few times and found them very accessible. I'm going to see if I can dial out the crazy tyre over heating the V8 in the softs and if it's not possible, then I'll take a look at the DTM as well as something like the M1 Pro Car

Any of you fine folks up for a bit of V8 tank-slappy fun tonight?

Was already on Easter family trip, but those things are pure joy to drive

Do you know how to dial out the high tyre temps? I have been reading up a bit and now realise that simply messing around with the initial pressure is not a good idea as it'll just cause the middle to get hot rather than distributing the heat across the whole tyre

Camber seems important. It looks like the IMO temps are in the telemetry, so I'm going to add those channels to the capture to see if that can help.

In Ams2 I never tried what’s working. In real life there are different approaches, from tyre pressure over lower damping rates and Cambet etc. But even in real life I think most of those are speaking out loud opinions

From my experiences in rl tyre pressures and damping rates don’t do anything in a useful amount. Sometimes as a sideeffect tt changed, but if you run a damping rate at the FA that is absolutely overdamped you may get higher temps because you’ll just scrub the tyre. But the setup and laptimes will be sh*t

Camber also has an optimum for each tyre, pressure, wheel load, kinematics…. Also no way I’d leave the optimum if I found out where it is.

What will have an effect is everything heat or energy is made in the tyre. So air temp, track temp, brake temp, lateral and longitudinal slip and a bit of deflection the tyre is doing.

Deflection you can change with everything that effects the spring rate ratio from the tyre to main springs (pressure, camber, main springs, arbs, damping).

Braketemp with blanking.

Lat/Long slip is the best in my opinion. Abs/Tc, static toe values and just the pure car balance. If it’s one tyre getting to hot or one axle there may be the problem in car balance. There you’ll have to find the reason, so at which corner part it is happening and fix it.
As an example: Everything drives fine but RA is getting hotter and hotter and there’s one tight hairpin. With an open diff the inside rear spins every time at the exit there and produces surface temp like hell. You’ll see it in the slope off the surface temp. Over time this heat is transferred into the tyre core temp. In this case raising the diff power value might fix the issue.

Yeah something like that, hope it helps
