I am hopping for 600 want to keep the rpm’s below 5800
What I have so far eq heads, cmi’s e tops, 1050 dominator 9 to 1 static
i really like the looks of the fab aluminum

The Sniper intake does look cool. The dual model with twin sniper injectors would be bad ass. I haven’t seen any reviews yet.https://cimg0.ibsrv.net/gimg/www.off...f870796b1.jpeg

It does look cool so I checked it out myself. It seems to be unstable with any sort of heat and the bilge is quite toasty. They seem to be for you weekend hot rodders. I’ll steer clear of it myself.

This may be interest to you. You can skip on down to where they played with the Team G manifold.


Get More Power from a Chevrolet Performance ZZ502 Crate Engine

What is so confusing to me is all the high horse power Merc engines use Vic jr style or open plenum tunnel ram style intakes
but when you look at the operating ranges on paper they would not work

I *think* had the airgap been around when Merc was doing all of their development it may have been a strong consideration for the 600hp and lower models, but at the time the options were a truck manifold or single plane.

F-2 Speedy is right. I was shocked at how small the Victor Jr ports are when I laid a gasket over them. They leave a lot of material in there so you can match whatever heads you have. The airgap isn’t as bad but I still took some time to hog it out.

F2
did removing all the meat help?

Smitty has done some dyno time with the Victor Jr. You can see his input on the last couple pages of my build thread if your interested.

At the power your aiming for and your CI I'd tend to go single plane and port match. Dual plane do have awesome torque but think you'll sacrifice at top end. I only mention port matching because of your build. Honestly seen up to 50 hp gains on dyno back to back. Valako will verify. Some builds makes no difference or very minimal. Heck I've even ran Valako raised floor heads with a stock rec port intake and had no power loss. It was a weekend deal to get on the water but interesting. That was with a 454 build though with much less power. Look into the Merlin X intake. I'm not a big fan of them however seems like a lot of guys like them. NA 565 builds I'm using the brodix hv2001 unless I go back to sc. cross section and runner length is something to be considered also. Just my opinion..

Excellent points. I should also note that I do 90% of my boating under the 4K rpms and pull a lot of tubers and wakeboards. If I was going for the last few mph I’d do just as John said. I have an open bow so anything over 60 and I start losing towels, coolers, dogs, etc.

Was strongly considering this one, anyone use his stuff

Has anyone used the manifold in a setup like mine?

What cam do you have? What boat is this going in?

33 outlaw
still undecided was thinking of a 741 or a bob m special

Bob M has been thrashed on here enough, but what pretty much came of it was a lot of his stuff were Crane clones often the 741 being the most used. Teague also copies the Cranes by just a couple degrees here and there to keep the lawyers happy. I went with the Comp Cams 525EFI cam which is the same as the 741 but 114lsa instead of the 112lsa to help fight reversion. My last cam had 110lsa and even with dry to the tip headers my valve seats were getting some rust.

The 33 Outlaw is a Baja favorite. Great boat!

What kind of power you making?
what kind of exhaust you running
thanks for the complement on my boat
is was a barn find was tied up in a estate dealio
been sitting on a rack in dry storage since 2007 has a little under 100 hrs on hull
needs clean up and interior in cockpit but excited to get working on it

I haven’t gotten to fire it up yet so who knows, lol. I have Edelbrock Performer RPM heads with a lot of chamber work, 10:1, rpm airgap manifold, CMI headers, 525EFI cam. I’d guess it should be about ~600hp with the heads and manifold topping out there.

The Baja section isn’t as active as it once was, but I’d ask in there about power setups as that’s a popular boat a lot of users may have experience with.

I built my engine for more all around performance, plus I’m already on the edge of what a Bravo drive can handle.

I get the Bob M special ouch.I guess I should of said I would both cams the same, my fault.

Post some pics of that 33!

After realizing majority of boats use I'd give up a little power and look at the dual plane and go out and have fun. Not worth squeezing every bit of hp out of something that will not see WOT often and you can taylor the build around your needs. I've used dual planes for years and loved them. Again your CI gives you the flexibility without sacrificing a significant amount of power either way.
