Engine redline? - Focaljet

**baddadiam** · 06-29-2008, 10:14 PM

first i want to say that this is a great site. all of you that have answered a question so far have been helpful and polite. thank you. my 06 zx4 doesnt have a tach so im going to get one... whats the red line? also, do i need a tach adpter? (ive seen that ford racing makes one)

**InfraRedSVTF** · 06-29-2008, 10:29 PM

the redline i think is somewhere around 6500 and the rev limiter is at 6800 on the duratec but i could be wrong

**baddadiam** · 06-30-2008, 08:36 PM

yeah... i guess i could of just looked it up, but do i need the tach adpater?

**Aggie 08** · 06-30-2008, 09:18 PM

My zx3 didn't come with a tach either, so I bought a stock gauge cluster that had a tach built into it, and it hooked up perfectly. No additional wirring was necessary. The only downside is that the odometer doesn't adapt to your cars mileage. You can send it off to get it recalibrated, however I've heard it takes about 3 weeks, and if you drive your car in that time it will still be off some. But still I think that having a stock tach will look better than an after market one sitting on the dash.

**Foci_Fosho** · 06-30-2008, 10:10 PM

6750 rpm

Yes, you need a tach adapter.
No, if you decide to wire it to the Coil-On-Plug.

There may be another way to wire it up, but I am not sure.

**brads03zx3** · 07-01-2008, 04:59 AM

The non-SVT focus does not have a redline. The rev limiter is set at 6750 from the factory.

**hommie** · 07-01-2008, 12:06 PM

You will need a tach adapter to hook up a aftermarket tach.

**baddadiam** · 07-01-2008, 04:28 PM

thank you

**baddadiam** · 07-01-2008, 05:23 PM

does anyone know what shift light is telling me to shift at? and you really dont want to get on the rev limiter very often, right?

**hEaT** · 07-01-2008, 07:02 PM

That light is for fuel economy. Don't pay attention to it for hard driving.

**Aggie 08** · 07-02-2008, 01:46 AM

That light seems to come on very early even for econimic shifting. If I shift right when it comes on it'll be below 1,500 rpms, and the engine will make a stressing sound.

**sayin0487** · 07-02-2008, 05:52 AM

at wot on my 07 st the shift light comes on at 5k. and mine does not have a red line on the factory tach. easiest thing for you to do, and possibly less expensive would be to find a used cluster with a tach on it.

**arty** · 07-02-2008, 09:38 AM

The rev limit is based on weak valve springs. You can safely go to 7200 with tuning. With springs and rods 7500 is safe with a very max of 7800 for the 2.3L. Even higher for the 2.0L.

Does the power continue to increse at those revs?

With all the Cosworth goodies, yes.

With stock parts, no.

**baddadiam** · 07-02-2008, 05:06 PM

thanks guys. i think im gonna look for for a used gauge cluster. and i guess im glad i havnt heard the rev-limiter yet( i wonder where im shifting @... hummmmm)

**FocusSportVP** · 07-02-2008, 05:16 PM

No point in hitting the rev limit needlessly, but you aren't going to do damage if you do. Ford has CRAZY tests for rev limits. Trust me, its not a big deal to hit it. On our cars I have hit it hundreds of times, pretty much any time I dyno. No issues.

Just don't misshift.

ya i did that once, went to shift from 3rd to 4th at around 6400 and went into 2nd. scared the **** outta me... thought my car was done, but it was fine. but i hope i never do that again.

**OmniFocus** · 07-02-2008, 06:46 PM

2nd to 1st at 7100 RPM equals eight bent exhaust vales....

**Z63R** · 07-02-2008, 09:02 PM

...and the stock 2.3 dual-mass flywheel shouldn't be routinely taken over 7100 either. One would want a conventional, single mass unit for that application.
