Any way to increase power of 912iS?

It’s not something I would do, but this video from Edge shows the HP increase on the 912iS with their big bore kit.

If you do this there is a good chance you'll be tossing thousands of dollars and maybe and engine down the drain. You maybe drastically shortening the engine life. 

Why a d on what do you need more power for? Why not just get a 915?

I have a Sting S4 with a 912IS....love the plane and love the engine..

But of course more performance is always better. I have found that saving a bit of weight really helps...

1) Do I really need to take all that gear on each flight...pack for the day only

2) Do I need that much fuel ? and hour is usually enough margin, do I need to fill the tanks each time.

3) The hard one...I lost 10 kg myself....and suddenly my plane flies better !!

all of these have to be worth at least 5-8 Hp !
