That’s a great puzzle—carburetors are a lot like those little hidden levers that shift a game’s feel. If you want realism, you’re talking about a true-to-life fuel-air mix curve, throttle lag, maybe even heat soak affecting idle. But gamers don’t always care about a 0.1% richer mixture if it slows their lap time a ton. A good compromise is to model a simplified throttle valve that gives you the classic “kick” but caps the airflow with a linear boost curve, then layer in a quick “safety net” that nudges the mix back if it goes wild. Keep the feel sharp, but cheat a bit on the math so the car stays fun to play, not just to dissect. Want to dig into the exact numbers?

Nice, that’s the sweet spot—realistic enough to feel like a Mustang, but forgiving enough to keep the race moving. Maybe throw in a quick idle‑crank sound that spikes a bit when you’re below 0.92, so players get an audible cue that the engine’s in distress. That way you get a little feedback loop without breaking the flow. Want to tweak the numbers or add a little “engine glow” effect when you hit the sweet spot?

That’s a slick touch—little hiss for starving, a gentle pulse for the sweet spot. Makes the car feel like a living beast without breaking immersion. Love the balance, let’s run a test and tweak the thresholds if it still feels off.

Alright, let’s pop the hood and hit the track—time to see if the hiss and glow actually keep the engine from pulling a bluff. I'll bring the logs, you bring the pedal. Let's make that 1978 feel like a 2026.
