I had through about going low profile in my boat when i originally did the setback but i was told not too. How much of a difference in degree's does that intake make over a stock berk? I'm trying to get my hands on some wedges before i go out in a couple weeks to just test and see what the do. I borrowed your snoot from a local boater. So far the snoot has made a HUGE difference when cruising. The boat with the droop wanted to porpoise before in anything but smooth water and now with the snoot it runs like it did stock. I can tell the boat is alot wetter when cruising though. I think the droop was trying to fly the nose too high when cruising and it wanted to fall on it's face, just my guess.
very similar results as what i had,i couldn't run the droop at all.i bought the straight snoot with no pin angle and ended up with a 6 degree up wedge.
but my pump is a E-pump so therefor any one goes oh they suck(not really if treated to some homemade upgrades)anyway really shouldn't matter b/c my pump is like a set-back already and i had all the same problems you are going threw.
got mine 80 percent cured and give up.all this started years ago when i took all the hook last 8 feet out of my Taylor Sj.
mine i cant cruise with the diverter up over the 3rd hole unless im going 3500 or above.i can cruise with it in the 5th at around 3800-4000 just depending on the water.it loves small chop.
smooth as glass it sucks bounces like hell.get much more than 12 inch chop it jacks with it also.
i can run hard in the 5th hole which is my best position for my boat,on glass and small chop with no bouncing,but when i let off it sets down hard,especially on the juice.
so do tell more about all the wedges in this boat,looks to be very outta whack and should imo bounce like crazy unless balls out
What degree is your ride plate set, does it have a shoe, does it have a loader? If the only way it will run is with the snoot set like that you guys got somethin way outa wack. I'd put a droop back on it and start from square one

i have also heard the 5 degree agressor is not as good as the mpd low pro?
any truth or tales to this?
The boat does not porpoise at all like it is set up. We tried a droop on it and it goes bouncing crazy. It is a very touchy set up. It has 12 or 13 degrees of wedge
The shoe is a 1/2 degree tapered shoe and about .190" above the keel line. The ride plate is set up one more 1/2 degree from the shoe. That is the part that is so touchy. Add two washers under the cradle and the boat nose hunts and will not run any speed. Take away more than 2 washers, and the boat gets violent. It will jump clear off the water and it does not get pretty from there on.
By doing the heads and putting in a different cam and intake manifold this winter, the HP went to 651 hp @ 6300 rpm when we dynoed it this spring. Seems like the added HP actually made the boat handle better. As of yet because of the new engine, I've not had it above 5000 rpm and about 86 mph yet. Actually I'm about half scared of it.
Yes, the MPD intake is a much better intake than the Aggressor. But I don't believe either should have been used in this application. If it wasn't such a job, I'd like to pull the Aggressor and try a Dominator SS intake or one that I had shoed myself.
However, it is the most free running and easiest boat to drive I believe I've ever been in. But everything has its limits. I think it's time to put him in a tunnel before someone gets hurt.
There' just no way to make this boat work with a droop. I think the outa whack has to do with the bottom of the boat and the 5 degree low profile intake. It had some rocker in it. It is also very heavy in the front and very light in the back. Jerrod weighs about 80 lbs. less than me and it handles a lot better for him.What degree is your ride plate set, does it have a shoe, does it have a loader?

I've had about every possible combination on this boat you could imagine and this is where it settled down and runs its best. Ran and data recorded 62 different set ups to get to here. At one point, I though we'd never find a sweet spot for this boat.
It basically runs perfect like it is, but one little variation from this set up and HANG ON!
Duane, what you just described sounds exactly like what i'm seeing. I'm no expert, this is my first boat, my first setup, my first everything. But from what i can tell, my boat just wants to drive straight up out of the water and then falls on it's face. I have to run the PD all the way up with the droop to get the ass planted and even then it's just bearly hanging on and to me feels like it's waaaayy too dry. I got it to run 96 MPH on GPS, only once though, i also didnt stay in it very long. It starts to scare me alittle and i have not had perfect water to run in. Another problem i have is that on launch the boat wants to take a few bounces. The RPM's during these bounces go from 5000 to about 5500.
I swapped from the droop to the snoot half way into the Tom Papp deal at elsinore. Unfortunitly Jack and Chris had already left by the time i got back. Like I said earlier the biggest difference I noticed was cruising back to the cove. I went all the way accross elsinore and it was like I had my old boat back. It just cruised, was easy to handle and didnt want to porpise one bit. Once I got back to the cove i made a few passes. On launch the biggest thing I noticed with the snoot over the droop was the fact that the boat didnt want to wheelie out of the hole. With the droop I had to run the PD pretty much all the way down or the whole damn boat would want to do a backflip. With the snoot i had to run the PD up to get her up and out. I wish i had more time to play but i had my Dad and Son on the shore and it was getting cold and late.
Duane, I just tapped my intake to take pressure readings. I'm heading out to the river next thurs and plan to do ALOT of testing. What kind of pressure are you seeing on the suction hi and low? I'm going to try to get my hands on a couple wedges too. I have a tappered shoe now, i'm not sure the size or the amount of tapper in it. I also got my plate set at about 4.5* up right now. It was closer to 3* before.
Have you tried not running any droop?
One mistake you may have made was moving the pump back. I was told by several people not to move mine. My Kachina was damn near the same hull as yours and with a droop and no ride plate or pump wedge it would do 90 perfect off the bottle. I never gps'd it with the 250 kit but it still stayed in the water very well.
Duane definitely knows his ish. I called him a bunch of times when set'n up my TX. I'm just try'n to give ya idea's

"Don't make me get my penguin"
I gotta ask 1 question.
How the crap are those studs holding up?
Think I would have taken a different approach.
But If it works for you that's Kool!
