That shark looks AWESOME!!! Now, if I sold the house and the kids, put the wife out on the streets..........

I'm sure SOMEONE will take this incredible aircraft up.

As to modding Lyc. 540s, there are two main shops. Dick Demars Fire Wall Forward and a group call Lycon. They will do a number of mods including porting, polishing, putting in after-market cams and higher compresstion pistons.

I've read various figures (some a little generous, I don't think Sean Tuckers aeroplane is putting out 400hp) on peak HP. I think a 540 with "The Works" might be getting 360hp at around 2900rpm.

I used to own a Laser which had a Demars IO 360. Stock 200hp and it put out about 230 at 2750 rpm.
