I really like my stroker motor. It is not much larger than your 1915. It is a 2110, a 90.5 bore and 82 stroke.
It once was in a beetle and compared to a friends 1915 in a beetle it was a torque monster. The 1915 ran good and strong but the added stroke of the 2110 made mine a wheel toter.
Quite a few years went by with the 2110 sitting in my shed. Then I had the bright idea to build a trike. So I freshened it up and put a much smaller cam in it. I do not run Engle cams, I prefer a different lobe center than what they are made at. But my small cam closely compares to a W130. It sounds like a lot of cam but it dont bog at low rpm like a stock stroke. You definately know when the can comes in though.
The downside? You are adding a lot of stress to the engine case and bearings. I replace bearings every 20k to 30k miles. If you are looking for long term durabilty with little maintainence then do not go overly big. A counter weighted balanced crank of a near stock stroke does wonders for bearing longevity.
But after saying all that.... I would clearance the case and put an 82mm crank in it. 2276cc Mmmmmmmm. 94mm jugs did not exist when I first built mine in 1981 (I think). 90.5 were thought to be more durable than 92 jugs. Next time it is apart it is going to get cut for 94's.
