Really...25 hp?.....Really. Guess since it's on the internet it has to be true.

Who else has all that machining equipment to make their own parts and a dyno?

25hp very possible with a cam at higher rpm plus it has higher compression, but I have no idea what cam that is or what rpm it runs at. I know mine will pull away from a stock clone and still has the stock cam and carb.

The whole dyno chart is posted on their facebook page if you need more info.Also posted are dyno results for 23 hp vanguard and 22 hp predator.Also shows the cvts create quite a bit of power loss I guess due to friction.

I have been drooling over that swap for my g16.

Ha, and remember cvt has more friction with a stronger spring in the secondary. You only want enough to keep it from slipping. They also have more loss under high loads (like a dyno run) and less at part throttle, if the helix is working. I better go look at his dyno page.....

The mildest one we built was a stock engine with ported & milled .100" head, timing key, chromoly pushrods, and 1.3:1 rockers. Stock rod, flywheel, cam, etc. It made 24hp 25tq. Ill see if I can find the dyno sheet.
