I agree with Omar.  There are several big HP gullwings around.  If you look on the performance boats site and search for slow burn, you'll see a vid of him testing a pop-off with a big HP nitrous motor at speeds around 115.   If you want a race boat and that is where it will see most of it's use, then a tunnel is probably the way to go with that kind of power.  If you're going to build a river boat that will once in awhile see the track, then I think the g-wing is a better choice. 

The g-wing will ride very well, turn, allow you to actually sit in the boat instead of on it, and still be lightning quick.  I know several g-wingers consistantly run well over 100,  but my personal break down is about there.  If you want to run consistantly over 100 and race often, then go tunnel. 

In either case,  I don't think the hull you have would be a safe option to keep that kind of power in.   Good luck with it and feel free to call anytime.  Jason

Next one goes in this week....  Who's next

As of 12/2/13, there is an all white one he was trying to help the owner sell for a GOOD price. It was the first boat out of the mold I believe and still has no holes cut into it.

Try sending him a private message or do a search for his contact info.
I believe he sold the boat molds to California Performance Boats and you would have to contact him about a new build.

Good luck.
