My hypers we fine until I ran too much timing!

lol.

In the past, it was generally agreed upon that the reason power fell off at 5k rpm was that the valve springs began to float. Every car, just like clockwork. Then people started putting schneider HD springs in (100lb seat pressure vs. 74 stock) and weren't able to raise their powerband. Then people started realizing, very slowly, that it was the exhaust housing and wheel that was the problem. As soon as you get away from mitsu-based bolt on turbo's you will find that you can make power much higher up and you don't really need HD valve springs till later, maybe when it's time for a cam.

Everyone upgrades the valve springs, it's like one of the first mods. So it's hard to say what can be done with stockers.
