I don't think you want to remove the rev limiter but, the speed limiter could get removed. Alberto will tell you all about it.

Get one of his chips or the EEC reflash--americanmotorsport,com like Bob said

Removing the rev limiter is a good idea if you plan on getting a MSD DIS 4 multi-spark controller. It has a built in "soft-touch" adjustible rev limiter. Otherwise, don't remove it.

I also reccommend Alberto.

Hey, I forgot to mention in my first post, welcome to the TCCA! For the icon to the left of the post, it's called an avatar (no idea why or where the word came from). You can upload one using the "my controls" option at the top right of this page. Click on that, and you can select an avatar to upload. You can also upload a signature if you'd like as well.

While you're at the top of the page, check out the link alllll the way at the top right titled "garage". You can enter pics of your car, modifications, etc there, then you'll have a little garage tag at the bottom of your post blocks like mine. Let me know if you have any trouble with any of this, and I'll be glad to help you out.

The only time it is limited to around 4,000 RPM is when the transmission is in park or neutral and it is a safety issue from both a transmission longevity standpoint and if it were to accidentally slip into gear (Reverse or drive) at that engine speed, it would damage the transmission and could put others around you at risk for injury.

On a stock engine, there is no need to remove the rev lmiter. By the time a stock engine hits the rev limiter, it is done making power anyway. The engine should never hit the rev limiter anyway...... the trans should shift just before redline if everything is operating normally.

Agree, and sometimes it is well past the peak torque and better to be in the next gear.

Essex peak torque ~2400 rpm
Vulcan peak torque ~3300-3900 depending on year
Duratec 30 peak torque 4400 rpm

Easy to see why the Essex was such a comfortable engine for family car use. Reached peak torque at about 75mph. However max HP came at a lowly 3800. I think about 4400 was max red line. In the tradeoff they went for GRUNT. I had 4 of them and they were comfortable and quiet.

As a side note, the Intech 4.6 gets both low and high torque with a flat torque curve.


Wanna here staight pipes and 120 mph at 3800 rpm?

Yes, so if one would want to launch it, I will rev it up to some 5500 rpm in N and then drop it on gear (sliping the clutch, manual transmission preferably). RPM's will drop to 4400 and the extra rotation inertia will help start moving the wheels.
I don't plan to find out what happens if you do that on an automatic.
