Raising The Redline On The Z

johncy2000 · 09-01-2012, 09:28 AM

Hey guys I was just wondering how many people that got thier Uprev tune raised the redline to about 8000rpm. Is it safe for the valvetrain to rev this car that high? 7500 is promising but 8000 would be great especially with G3 Intakes! Thanks for the input guys! -Johncy

According to my tuner,the power dropped sharply after 7200rpm,don't make a point to rise the redline.

Didn't someone on here just grenade their motor after banging off 8K a few times?

Perhaps advancing the timing instead is a better option??

You can raise the redline to 8k doesn't mean you should rev to 8k!

I have my redline at 8k

I have my stock rev limiter set at 7k

I have my secondary limiter set at 7300

I'm shifting at 7500

I have the injen long tubes, AAM complete 3" single! Car sings all the way...

Please check your info before confirming something like that.

The real issue wasnt just the 8k rpms. It was clearly also an oil starve issue. It happened during a time attack...

You would be fine to raise to 8k. just as said before just because you're bumped to 8k doesnt mean you have to shift there.

SS_Firehawk · 09-04-2012, 01:38 PM

Had mine at 8k, just be sure if you do adjust it, your not hanging there for any extended period of time. It's only worth it if your running the 1/4 and running out of gear or taking it to the track where there may be a few instances that you'd need the extra rpm.

anthonyy · 09-04-2012, 04:06 PM

Why even risk it? Rob at Z Car Garage wouldn't even do this.

n point on running more rpms that have a dramatic hp drop up there...

If you can hold the power (no loss or gain), then it will alter when you upshift where you are in the power range. This could help in racing, but most who have raised it showed loss of power as you get above ~7500.

Remember that gears multiply torque, and lower gears multiply torque more than higher gears, so even if the power drops off you're very likely accelerating faster at 8000 RPM in the lower gear than if you had to shift up sooner.

Will it hold together? That I can't tell you. But it would have to be an exceptionally steep drop in power to not be worth it if it would.

I would not do it.
