Why do you like turbos better than normally aspirated engines? Just curious. I would think that given a 250 Hp turbo engine and a 250 Hp normally aspirated engine, in the same car, that the normally aspirated engine would "perform" better. By that I mean the NA engine would not suffer from turbo lag; albeit slight, or not so slight as some have suggested. Also, I would expect the NA engine to provide greater engine breaking. I certainly appreciate the improved gas mileage of a turbo. And, I expect the NA would be heavier and thus reduce performance to some degree. Don't get me wrong, I thoroughly enjoy driving the Saab turbo. I find it to be very smooth and haven't been bothered by the turbo lag to any great extent. I have felt it on occassion. As when "poking" it to dart through traffic when approaching a left hand turn at a light. Other than that, I generally accellerate more smoothly when passing, etc, and have not felt at all hindered by any lag. Though, I think the lag in my car (2002 9-5 Aero) is less than others on the list have suggested. I do, however, wish I had greater engine breaking ability. Even at high RPMs in low gears the breaking is just not what I would expect. Dave JTK wrote: > I have also read about it, sometime this summer/fall.
