It’s an acquired taste, I know, but as a classic sports car racer I’m enjoying tuning and racing the vintage racers: the Auto Union type D, the Maserati 8CTF, the Mercedes W154, even the blower Bentley and, now that I finally had the money for it, the Alfa Romeo P3. I’ve managed to chassis-tune most of them - not great but reasonably well - but this Alfa is an unmanageable animal on the track. I’ve played my usual tricks with spring rates and ARB settings and so forth, but in a race it’s a problem even keeping the thing on the pavement. And while I can win races with it, they’re the most ragged victories I’ve ever notched. Sort of slow-motion train wrecks.
So, a question: is anyone interested in doing an open-source tuning for this beast? The limits are stock engine at 285 HP (although I’ve experimented with the race carburetor for a 10% HP bump, hoping for a bit of a speed edge, but at a cost in handling), and I’m staying faithful to the original RWD. Stock tires, but all other chassis tuning mods are expected. My test track is Astmoor Heritage Circuit, and I’m circulating at around 1:16, two or three seconds slower than, say, the Auto Union. Here’s my current setup. I usually start with Hoshi’s base tune, but for this one I started from the game’s stock settings.
Tires: 30 psi
final drive: 3.80 (circuit gearing, other gearing stock)
alignment: -1, -0.7, 0, 0, 6.0
ARB: 20.67, 9.07
Springs: 325.0, 210.4
Ride height: 3.3, 3.7
Damping: 11.5, 11.0, 5.1, 6.0
Differential: 40%, 30%
I’d really appreciate some help from some of you ace tuners on this beast. Any suggestions would be appreciated, and a full tune - open-source, not locked, so that I can learn from it - would be preferred. While a locked tune could be raced successfully, that’s not what I’m looking for here. I really want to learn how to improve my skills in this area.
