Can someone help me estimate my HP

I can make it sound like the vid, and only need a sazall and a cresent wrench. Use the saw to cut off the exhaust. Use the wrench to loosen the dizzy, and toss the timing out A little untill it will barley run. There you go you get the sound and very little go. And did it for 10 min of your time. No need to buy a cam..........
