Will the stage 1 kit be effective if I still have the governer in the engine?

I have a predator 212 (hemi)

You will still see gains but you would be limiting yourself to the gains through the higher rpm as the governor will kick in. But you will still have some gains until the 3600 rpm range.

Ok Thank you!

I just got a non hemi not too long ago and I was concerned about the governor myself. I’ve been backing the throttle limiting screw in and out and using a tachometer to see how it effects the gov. I posted a video of my findings but my engine will turn 4400 rpm with the throttle screw all the way out. I believe the screw was in 50% stock. I think kartfab commented that the governor spring isn’t strong enough to withstand the tension. I do notice that the governor will kick in and increase the time it takes to get up to 4400. I’m wondering if 4400 is enough to kill the governor over time.

at 3600 rpm with governor intact and funcitoning correctly, you will see about a 11-12% increase in horsepower. If you completely bypass or remove the governor, you will see higher gains all else the same as the governor is limiting flow by closing the carburetor throttle butterfly.

The additional benefit is that you will be able to rev higher without going lean, which is feasible up to valve-float with the governor untouched. so instead of going 3600 rpm, you back out the screw and you go 5500 rpm, which is a 52% increase over stock rpm, which will translate into a 52% higher top speed.

The three things that make horsepower are flow flow and flow. The three things that help the most with flow are cylinder head, camshaft, and carburetor in no particular order. If you have all three its like friggin zelda getting the triforce.
