Governor ?

[electraglide]

I hear people talking about removing the governor from the engine to up the speed. How does that work ? Is it worth the hassle .... is it a hassle ? Is there an alternative other than just leave things be .. ?

IMHO, no it's not necessary for everyday riders, backyard fun time, trail busting, mud hole stomping vehicles.

For drag racing only, then yes remove it completely. But dont expect it to be a daily rider without alot of maintenance.

Heres 2 small blocks that make really strong low rpm torque and theres plenty of power on the high side, with the governors working.
Turns more rpm then normal predators and 196 clones right outta the box, because of the better combo of parts and tighter tolerances. Better cam profiles, air boxes, exhausts, rods, heads, and carbs.
The stock small block preds and clones are done at 4800-4900, there's jus no more hp above that rpm for them to pull anymore.
So removing the governor for more speed is NOT the answer.

A little bit of tuning, thinner head gasket, timing key, and open the main jet up to .031" will make the small block preds and 196 clones safely run to that 4900 rpm mark, and live a long life.
It's jus gonna take a better combo of parts to get ANY more rpm.

It's the same with big blocks, except at a lower rpm.

These are utility engines, we have to make them good, reliable, recreational vehicle engines.

Hope this helps.

Thanks for the explanation brother. All that paints a different picture in my mind. Guess I'll follow the old cliche KISS. The need for speed kinda faded some years back .......

What no one ever really talks about is that the governor is adjustable for different RPM but most people either advocate for keeping it or removing it altogether, no in-between.

Standardized max RPM from the factory is usually set to 3,600 which corresponds to maximum speed on the throttle, and that is where garden tillers or lawnmowers make their advertized power. Your engine says 4 horsepower? Well it makes 4 HP at 3600 revs. It is okay to set the governor for higher revs but within reason.

I think the engine manufacturers discovered that excessive wear was occurring at 4,000 revs or higher, so for maximum engine longevity, they set their governors for a lower engine speed; they decided on 3,600 (or thereabouts). That was a long time ago however and engines are a lot more durable today.

I'm not telling you if you should or should not remove the governor, but most of Pred 212s and Briggs and Stratton motors I remove the governor.
I get a faster throttle response, and more speed when I remove the governor. But I also do some other stuff to the motor when I remove the governor.

Thanks Hellion and Pearl111 ... all that makes sense. All or most motors can run at peak, full throttle or beyond max but why would anyone want to do that unless you are Vin Diesel ........
