unless you plan to reinforce the rods/pistons and basically every moving part in your engine I would suggest not going above the factory redline. you can, but your engine has a higher fail rate once you break the redline. More than likely one of the tie rods would snap off and dangle off the crankshaft and go through your oilpan on one of it's revs. Floating Valve is a valve that never closes from _--_ to ___ the floating valve never makes a complete seal thus the intake and exhale of the motor is pretty powerless (robbing you of power, and unexploded gases), which is why you should replace the valvesprings, and possibly the valves, and have them well oiled, and properly seated. if you do want to raise the redline, you should get a higer rated tachometer and just hook that up instead of your stock meter. ones rated up to 10,000 rpm you can buy at any auto store. but I reccomend you don't go too high above the factory rev limit, you risk blowing your engine. and after a certain point you raising the redline on a turbocharged motor the turbo will loose effectiveness the higher the rev range.. because the compressor fan can only spin so fast to drive the intake fan... higher revs will allow you a better shift change, and lower your times, but only to an extent.

good luck, anyone want to fill in on what I missed, and possibly something I said wrong?
