I have less brap than he does... why do you think?

Think about it:

That's the difference between a pro tuning a boat, and a bunch of knuckleheads on an Internet message board e-tuning a boat.

There's more to it than just matching carb and pipe settings.
The head pipe settings don't always transfer 1:1 to the next head pipe (casting differences?)
I am sure Art didn't just look at some chart to set the screws - he probably tuned it.

You say the only difference is that Art tuned his boat.
It seems clear what's missing then. Right? :biggrin:


Edit: I am the biggest knucklehead of all of them. But I won't pretend to know what a pro like Art knows. Essentially you're asking to duplicate his work, without the charge. (I don't blame you)
Just remember, you get what you pay for.

I have been talking to Art at jetworks about this, but I just thought I'd write a post to see what you all thought also.

Bluegtate and I have practically identical setups with the exception that he has V Force II's reeds and I have V Force I's. He also has a limited chamber while I have a mod. Other than that, identical setups. He has a 13/16 solas 3mm cutback while I have the new 9/15 hooker prop, which should have better bottom end than the solas.

Bluegtate got his ski power tunned at Jetworks, and I have tried to match his setup exactly, but no matter what I do, his has that more brap on the bottom end compared to mine. Trying to figure it out. Bluegtate's is the hardest hitting stock 701 I have ridden.

62t Cases, 61x cylinder
Riva Single carb conversion manifolds
46 blackjack carb
B pipe
175lbs compression
MSD enhancer
Flow control valve
Light flywheel

I'm trying to figure out whether maybe my reeds are just worn out, as I have read the VF I's commonly do, or maybe my engine is just tired and needs a rebuild, at least a top end rebuild.

The answer is clear to me, they are not as similar as you think. The limited chamber is much different than the mod, and pump tuning is a whole other ballgame. An example is my brothers boat, same pipe, different cylinders, different props, although they are both good they are a bit different on power delivery and how they rev out. That Hooker probably loads the motor hard from start to finish, and the Solas may momentarily spin allowing the rpm to come up then "BAM". Personally I think the setups are close at best.

Its your chamber honestly. I swapped a mod for a limited and the difference is unreal. My mod was great on top, but was soso down low. With my concord 13/17 prop, it rips low,mid, and on top is about the same as a mod pipe.

Since switching to a hooker impeller today, my ski feels even better down low and still pulls on top end(have yet to top it out since i could only ride 10 min).


Try swapping chambers. I didnt think it would make that much of a difference, but in reality the limited chamber is the best freeride/freestyle choice for low end power.

i didn't think the chambers made that much of a difference per the knowledge given to me by Art.

Ski felt the same even with my solas prop.

But you are all right, if I want it perfect, I need to take it to Art. As stated before, I don't think it warrants the +- $200 it would cost for me to have it powered tuned by Art, thus is why I was trying to see if anybody had some sort of suggestion that hadn't been previously suggested to get "that much more" power out of my ski.

Also, from everything I have told Art, he thinks it is that I have V force I's. He said those are crap, and wear out very quickly compared to II's. He suggested switching back to my stock fiberglass reeds to see if it alleviates any of the problem.

Reset timing with timing light. (Borrow tools from friends/Free)
Replace Needle valve assembly.($22)
Replace reed petals. ($100)
Buy a LIMITED chamber. ($250)

P.S. Fourm posters: Please refrain from calling me an internet knuckle head!:twak:

I was under the impression you fall under the "Pro" category.

Was I mistaken in that? And are you saying you can e-tune a boat just as well as you could in person?

its amazing how much better a boat can respond with new N/S. Also test both pop offs and get them as close as possible.

If there was someone within 100 miles of me like Art to powertune my boat in the water, I would be there as we speak. That would be worth $300 bucks to me, just to make sure I was spot on.

brand new carb internals include N&S.

i do need to test the pop off. Been meaning to order a gauge, just haven't done it yet.

Rode again this morning after adjusting a few things and the ski runs sufficient enough for me until i get an engine built. thanks for the advice everyone.

not just the money, its also time. 2 hour drive there and back with no traffic, which highly unlikely when you drive clear through Los Angeles to get there. getting married in two weeks and just don't have the time. possibly after I get back from the honeymoon.
