Hi,
I've recently bought an S4 (year 2000). No mods added or planned. Some questions relating to how I'll get the most performance out of it...
- at what revs do the bi-turbos kick-in? About 3.5k?!
- does it use an electronic accelerator pedal? It feels like it does. Just never read this anywhere.
- if I drive the car from a cold start, allow the engine/oil to reach their normal temps, and then drive the car hard, I find that it's initially less responsive. But as I continue to drive it improves slightly. Not a huge difference, but noticable. If this normal? If so, what accounts for it? Turbos heating up?!
- air-con on or off?! Negligible I'd think given the engine size of the S4.
- full tank of fuel, or 1/4 tank. Negligible weight difference I'd think.
- use a performance fuel (e.g. Optimax). Probably helps, not sure how much.
- when preparing the car for a short but quick burst of accelaration (e.g. overtaking), what revs would you aim to kick off at? Would 4k be about right in terms of avoiding turbo lag and gaining max torque?
thanks
Gordon
