so redline is a factory suggestion with the setup as sold?? I was wondering this myself while reading about race engines hitting 8k. That would sound cool at that rpm. Anyone with a sound file??

guys!

wait a sec, dont go pushing your car to the limits just because it makes horsepower up there now! the redline is set at 6.5k rpm because above that, without some valvetrain upgrades your pistons would hit the valves... yes people push stock Z parts pretty far, look at norm with his 7k rpm redline, but I wouldn't go much past 6.5k, unless i was really in the mood to rebuild a motor.

do what you want, but dont say i didnt warn you,

ps, is there no rev limiter on the 280z's? probably not, just wondering...

All that i know is i have a built motor with about 240hp out of a NA L28 and 6600 is as much as ill take it.. Listen to the motors when they get up there its scary they sound super stressed. And the vibration at that rpm is crazy.

No, it doesn't effect redline.

With your mods to your engine, you're just flowing more air through it, letting it rev up quicker and easier, thus more power. But you didn't do anything with the internals, so your stock redline remains. You can bring up the R's as high as you want, but think about the added stress that you are putting on parts that weren't designed to be subjected to that. KABOOM! When you hear that, you will know that you will not be able to go any higher (or go anywhere for that matter). Just play'n, but be safe, keep it within the limits, keep your Z alive.

Re: guys!

Yeh rev it hard, i wanted to see what my bog stock auto 240Z would rev to so one night i just held it in 1 and she got up to 7800!! Seemed to hit a wall there, i didn't hold it though. Might have gone further. But the 240Z redlines at 7000.
