Thats what Ive been hoping for speed wise, still not getting there even with 900hp.. fail!

Well you have the motors out already. Stagger that b1tch! Lol

IDK if the flatdecks were significantly heavier or not, but a straight bottom TG with 900's should pretty easily break 90 if set up correctly (it should run closer to 95). I'm assuming you've played with props... are your drives possibly set to low?

With TRS huh?

If the flat deck is built the way I think they are then yes it's way heavier, the deck on my boat is much thicker then a Cafe, I would assume Flat decks are same way...I know when on the bow of my buddys flat deck it feels super solid...

He's pretty dialed in. Boxes, prop shafts close to even with the bottom, Big shaft #4's, 17.5 Diameter labbed merc props, etc.

My buddy Brian had a 90 Top Gun. 800HP 598ci supercharged engines. Dynoed in full marine trim. Best he ever saw was 87mph. I was on it in flat water, trimmed out, 82mph. He painted it with a 90mph scheme, just never got to see 90.

I can see where the original 90mph guns needed 850's to see 90.

As for the Flatdecks, I know RMPRAM had 1100HP psi blower motors, and he got 100mph with V's on boxes, and low 90's I believe with 3A's.

Theres a 1994 Top Gun in the classifieds with Hawk 600's and bravos, that states Top Speed at 75mph.

My 93 top gun ran 96gps with 875hp. Very high x dimension 3A drives. 1.62 gear ratio. 5 lbs of boost. Motors were easily capable of 1000hp with pulley change.

X dimension raised twice at TNT

what does kite mean?

Lol porpoise just another term us local guys have used

Yes, I've seen it myself. Factory 1994 drive height. I believe the engines dynoed at 704 hp IIRC.
