Wyay to bring this way off topic, but:

1) there is no power up there. It's simply over-rev. I run 256/264 cams. I'd need at least 270/280 in order for there to be useful power up there.

2) I usually take it to 8300 when i'm revving it out because I can't shift the transmission past that. However I have a Pfitzner Performance Gearbox 5 speed helical dog engagement race transmission on order, so that should solve the shifting problems, along with a reduced inertia lightweight twin disc clutch assembly.

3) I have free revved it to i want to say 9300-9400-9500 before. It's not safe on stock pistons to spend extended durations up there, the same goes for the fasteners on the factory connecting rods. albeit very strong, but i don't need to take too many other chances. Basically, at that speed, I'm asking for the engine to come apart. Whether a valve floats, a retainer drops, connecting rod bolts, something happens. It's kind of dangerous. but whatever, I hang out on the thin ice, especially since i've lost over 30 pounds in the past six months.

4) I DID however, mechanically over rev in a 5th to 2nd accident that I want to say put me in deceleration from about 9500 or so all the way down. blue shift knob for the win.

I hope this information helps, since apparently the cool thing to do these days is play high school based 'he said she said.'

Lastly, I'm currently doing research on viscosity losses of lubrication fluids due to shock and vibration. rev-limiters have produced disastrous results on SRs, while free revs have not. Why is this? What is the reason? Are the current countermeasures correct? I'm not entirely sure just yet, which is why this is such an interesting topic to me. I know it is adversely affecting the hydraulic lash adjusters, but could it also hurt a solid lash set-up cylinder head? I have crashed my engine into the the 8600 rpm limit when i had it countless times. Especially in the rain and on soft tires. But I wonder if ti causes more wear than is necessarry. So naturally the next thing to do was to set the rev limiter higher than I would ever try to go. 9300. Well, that ended up being obtainable, so we went higher. I finally decided to leave it there because at least, well, if you're past that point. lets just view it as the point of no return. Or the point of complete stupidity. But I view my redline like this:


me at 9000+

everybody else ---> below clouds

So basically, I do so because I can, and you can't.
