Okay, I'll try to make this brief, and to make it as simple as I can possibly stand.....by the way, there's never a stupid technical question when you're new to this sort of thing. Your questions were just fine.
1. With the limiter removed, I've heard that the
E39 M5 (I think you're talking about this one.) could potentially reach speeds of around 180mph, or 290km/h. That is what I can recall from memory. Anyone correct me if I'm wrong.
2. I will make this as simple as possible. For the sake of simpifying the explanation, twin turbo just means it uses two turbochargers.
- Superchargers and turbochargers are both methods of forcing more air and fuel into the combustion chambers of the engine. They are different in the ways that they are driven.
-Superchargers are "turbines" powered by a belt connected to the engine.
-Turbochargers are "turbines" spun by rapidly-moving exhaust gases.
Superchargers, because they are powered from the engine directly, are immediately effective at increasing power. Because of the direct connection to the engine, they take a certain amount of power away. This is, of course, countered by the power that they produce, but it is inherently less efficient.
Turbochargers are more efficient because they are powered through the exhaust gases, which would otherwise be wasted. Technically speaking, they could
potentially produce more power than a supercharged engine could because there is no direct loss. The disadvantage here is that turbochargers suffer "lag", or the period where the exhaust doesn't yet have enough pressure to cause the "turbines" to produce a decent power boost to the engine. In higher RPMs, turbochargers reach their optimum running conditions.
3. It is impossible to say what it would be exactly, depending on the gearing, etc. but if eveything else on the car remained the same, I would estimate that the 0-60 time would decrease from 5.2 to around 4.5 seconds. That's not bad for a car that weighs 1700+ kg.
4.- Increase horsepower
- Increase torque
- Improve aerodynamics
- Change gear ratios (Shorter gears = better acceleration, longer gears = higher top speed)
- Reduce the weight of the car (As everyone who knows me is sure I will tell you, this is the best method. As well as improving straight-line performance, it will make the car more efficient as well as improve every other aspect of performance. All that you might lose are some wussy luxuries )
Hope this helps you a bit, and that
