Well my experience is limited to non tunnel boats, I do have a Rogers Dragstar it is a tunnel it didn't have a droop but it did have a ride plate and a loader scoop I haven't been able to run it yet it's being rebuilt as we text , I will tell you that the ride plate on my sanger and a droop did help as well as the loader scoop but that's my boat , I have talked to Duanne at Hi - Tech jet performance back east , he make,s a straight snoot I haven't bought one yet to try but I will ,he says the straight doesn't push the back of the boat down but more forward and doest bend the water twice all things I'm still learning I'm no expert but there,s alot of guys on here that know more than I do but I do know that you can have all the horsepower in the world , but if you don't set up the pump right you won't go as fast as you could, Tom at jet boat performance has helped me out alot, great guy , give him a call, hope this helped out😎
