The 1700 was the vw bus engine. It dont make a whole lot more hp in stock form, like 68hp versus the type 1 53hp. But does make more torque. It feels a lot lot bigger than a stock type 1. There just ain't as much hot rod stuff for them and what there is will be a whole lot more expensive.
So whatcha do inide the engine? Stock stroke? Big cam? Heads in good condition?
In a light trike with less than 100hp (at crank) a stock 800lb would be enough.
I ran a 1200lb bus clutch with a 150hp (at crank) engine for years, no problem.
I currently run a 1700lb and a 225 (at crank) engine and it holds.
If it was in a full body car you would need more clutch in each instance.
