So here are the results, I finally got the boat in the water today. So I changed the Dart intakes to Brodix HV 2001's, 950 HP carbs to 1050 CNC'd AED Dominators, Gill Dry to tip exhaust to K/E headers dry to tip exhaust, and -2 sportmaster to -3 IMCOs and Daytona ignitions. So far I've gained 500 RPMS and 8 mph. So top speed so far is 88 mph. That's without any tuning, I'll bought a 2 channel Innovative LM-2 so I'll be tuning it in with that. Either way, the boat is WAY snappier in the midrange than before and performs better everywhere. Getting on plane is tricky due to the -3's, but once up, it goes great. I'm 100% happy with the choices I made, a 1050 dominator is anything but too big. I think this carbs actually flow close to 1130 cfm's.

WOW - that is hauling the mail.
I am glad you are getting things to work out for the better.

Yeah, it was a nice improvement. I have no idea what the biggest improvement was, which is too bad, but over all to gain a solid 500 rpms is pretty good. I do need to make a new cavitation plate. Like you said, going to short will cause issues. I made one long and one short. The short one is blowing out when I try to take off. All the work needs to be done by the other drive, and I have to feather the cavitating drive until the boat planes off. The end result is, I learned a few things, and I'm pretty happy with the results.

Thats awesome. 88 is flying in that thing!

After you get it dialed in I hope you can break 90 .

Congrats endeavour32 ! I believe you passed what others have done with 540's.....if my dilapidated grey matter is working.

Got a link on that exact carb ?

Here is the link to the carb. The JimV ported heads are what is really helping out here, but I think they were being restricted by the little carb and Gill exhaust last year. I know a fair amount of people thought the Dom would be too much carb, but the throttle response is far crisper than it ever was with the 4150. This is a 3 circuit converted to a 2 circuit dominator on my engines.

Okay, thanks for the info. I looked that up earlier and I saw the 3 circuits (thus 3 air bleeds per throttle bore)....so I figured/hoped you got something else or the pic was wrong. LOL.

Nice !

That's Bad Ass! Did you consider using the AED spacer with your new manifold? I've been looking at them for my QFT 800 on the merlin intakes I already have. I know your boat is a totally different animal but I curious what the x dim is compared to my 311 trs. Seems like the boat really likes your "Setup". Congrats on the gains!!!

So, any intakes-carbs gonna be showing up in the swap shop?

I've got a 1050 Dominator that I swapped a guy for one of my Quickfuel 950's, but that is all I have. Everything else was sold over the winter.

My prop shaft depth is 4.5" below the hull. I started out at 7.5" below, so with the current setup it seems more inline with what is done on modern hulls. I haven't tried any spacers with this intake because I don't have the room under the hatch. The Brodix intake is about an inch higher than my pervious Darts.

Ha- yes I've enough horror stories about guys with 3 circuits trying to tune them for boats. I've got enough headaches that I don't need another.

Well now that I finally have the Formula all done, I did something really dumb, I bought another boat. Well just kidding about the dumb part. I just picked the 38 KAAMA Scarab that was for sale here. I'm going to be redoing the entire boat- new vinyl everywhere, new rigging, and new paint, and when time, the 509's will go in the boat. At some point the engines will get some 8-71's along with new pistons and I'll replace the TRS drives with #5's. So here is the new project, game plan is to have it done for summer of 2019. Once I start on it, I'll start a thread.

Congrats!
Words from experience, don't tear the Formula apart till the Scarab is close to completion. Did that last year, hindsight is 20/20.

Trust me I know. I'm taking my time with this, and when it's done it's done. I'm over killing myself with deadlines. How much do you have left to do on your AT?

Wax, gas and oil changes.
I had it out last September. 3 months of busting a$$ in the middle of the summer. Just had a fuel delivery issue. Junk in the STBD tank clogging up the pickup tube. This summer I've had it out every weekend besides this weekend, I took the cruiser out. Now I'm putting together new engines for the Panther to maybe eventually sell...

When I bought the Formula it sat for close to 8 years. The fuel was varnished and I had pebble like substance in the tank. I fought the "pebbles" clogging my pick-up tubes for half a summer. I don't know what to do about the Formula. It's worth 2x in parts than if left whole. I really don't want to part it out, but I'm also not going to sell it without engines for what I could sell just the ITS boxes for. Well I have at least a year to figure what to do with it.

This boat has been sitting for 4 years, I'm going to put a battery in it this up coming weekend and see how much fuel is in it. I'm hoping the tanks are empty.
