Looking at the thrust of the 404 (8 kN) and the empty & MTOW it looks like Gripen is not a very high powered fighter. (comapred to mig 29, F16, F18, etc.)
Although it probably is an excellent aircraft, doesn't this translate itself in average climb rate, limited sustained speed in high AOA dog fights and perhaps limited ordenance when operating from roads ?
With a 10/11 kN engine it probably would have a much better "jagt" performance.

Comparing Gripen and F18, Gripen has both an empty weight and MTOW about half of the F18's. Since they share the same basic engine, their thrust to weight ratio should be about the same depending on the version of the F18.
Also, considering it's a single engine jet, it will need to carry less fuel for it's operations than a twin engine a/c that weighs twice as much.
What I've heard, it has pretty impressive climb performance, and short runways don't seem to be much of a problem even at high take-off weights. It's also an unstable a/c which gives it very good turning performance.

Thrust alone isn't everything either.
Aerodynamic shape has a lot to do with it, and Gripen's shape is more advanced than that of earlier generation aircraft.
Then there's mission. Gripen's designated primary mission might not require as much thrust as that of the F-16.
