I engine brake all the time but get nervous when the tach gets close to red-line. I suppose full synthetic motor oil gives a little "edge" when in that condition.
What do you consider "Red-Line"?
The computer simply won't let you over-rev unless somehow you manage to top out OD (which would be somewhere around 130MPH with 225 tires). The stock rev limiter only cuts fuel, but the engine can actually handle higher RPMs. I've raised my shift points to 5400 RPM, and I think I set the new fuel cut at 5600, which I sometimes hit (that's WOT in 2nd gear at 70MPH), and I'll hold 5000+ RPM at WOT for 15-20 minutes at a time. I'm pretty sure no-throttle is MUCH easier on the engine than WOT :)
