Disconnecting the "rev limiter"
-
why the hell would you want to do this anyways?

Would it be a good idea for an automatic? If i did disconnect the governor would it still shift or would the RPM's keep getting higher? I want to disconnect my governor but I'm afraid my car wouldn't shift "seeing as how it's the "rev limiter" " so i guess my main question is "Would my car still shift after disconnecting the rev limiter"?Thanks The answer to your question is yes, the transmission will work the same, and No I wont tell you how to do it.
Like every one else said, why would you want to raise the red line? :icon_scratch: -
In many cars that I've come across have rev limiter set to maximize factory settings.
Using my swap as an example:
makes 240 hp and trq on an N/A 6. redlines @ 6200. Only available in an automatic, and uses 2 indiviual intake manifolds connected by an Iris valve that can open for "power" mode. Has serious breathing and exhaust issues.
If i freeze the iris valve open, remove the 6 miles of intake and put on a high flow filter, then run good exhaust, the engine can make power up to 7500 RPM. The reason they limited the reving was because of a shitty exhaust/clearing stroke on the cams plus the poorly flowing exhaust found on all subarus.
I'm sure other cars have similar setups...
do the research, what are the limitations and why? check, check, data log, then do...

Here is the stock dyno

Disabling the fuel cut (rev limiter) is going to what? -
Well, I just wanted to see if it was a good idea or not, guess it's not so great. I read off this one forum where this guy took his out, And he showed how, I wasn't really to keen on the idea so i wanted to know what you guys thought.

when they say "brake" they mean break, and what they are talking about is probably the torque converter. they can explode at high rpms, at least from what i've heard.
You should do other mods first, like different intake manifold, full exhaust, make the stock setup breath better, you'd notice more gains anyway.

Well my main reasoning for doing it before was to see if i were to get a "power gain" well now i see that the idiot who disconnected his was wrong, i think i will leave it alone. I am however going to build up my VG and turn it into a HP beast, im going to turbo it and while the engine is out of the car im getting a 5-speed trans. (if i can find one cheap) and I'm also going to build up my engine while i have it sitting on the engine rack.

Umm, the torque converter would be the least of his worries if he removed the limiter and felt he could safely hit higher than stock RPM. Valves could start floating, Piston to Valve contact could occur, anything in the heads could start breaking due to subjection to stresses it wasn't intended to see. Anything involving rotating masses would be subject to failure if he wasn't running an engine built to handle the higher RPMs.

Oh and before you even say it, Stock GT vs Stock 350 is a drivers race, and there is a nice price difference between the two.
