sounds promising.
where's your battery mounted?

In the bulkhead with a waterdawg rear mount kit

Took the ski out again today after fixing the leaking o-rings. Feels even better in the midrange and even picked up some lost response on the lowend due to that leak. It is still medioker on the bottom IMO but w/o question it blows the b-pipe away in the mid range power.

I am going to see what I can do with a enhancer next to help get it out of the hole and let the power come on a bit sooner. Carbs are not dialed yet but they are getting closer to where they should be. Fixing the leaking o-rings allowed me to make head way in that area.

How do you tune the PV's? Have you?

How do you tune the PV's? Have you?

I have 3 different spring sets that I messed with. There is also a external adjuster on them. One is a heay spring, the next is a sea doo red (low tension) and the third is a low tension that I cut a coil off of it. Starting with the adjusters all the way out I run each set back to back. When I get the best response I stick with that set and play with the adjuster from there. The different tensions work good for ball park tuning while the adjusters help to fine tune the set up. I am currrently using the low tension spring with the adjuster most the way out.

I feel the spring itself is correct but need to fine tune them once I get the carbs all cleaned up. Just got the carbs in the ball park today.

Do you have any rpm numbers? When do you feel the "hit"?

I would say it is safe to assume he feels the hit after someone swings a punch? Idunno, makes sense to me tho. WTF u been doing? You aint give me any poop in a while now, did I do something to piss u off??? LOL

 

[superramjet]

is your timing advanced at all?

 

[SUPERTUNE]

Get some timing in that engine... Use a TL so you have a way to pull timing out for this pipe. Use race gas w/ some decent compression.

Not yet. I am slowly building it back up to where it was. I plan to just install and enhancer and TBM flywheel here shortly.

Currently set at 190psi compression. Timing will be the next adjustment, then the flywheel, then I may mess with water injection.

I like the set up but am getting the impression that it really is better suited for a accessorized super stock or built motor. I personally don't think this pipe will obsolete the b-pipe by any means. Thus far this pipe is reacting like most dry pipes do. Somewhat squishy bottom with blistering midrange and top end. Adding timing, compression and a lightened flywheel just gets it to that midrange power band faster. The b-pipe is somewhat different b/c it is tunable and you can adjust the pipe to the motor, not just the motor to the pipe. I am not drawing any conclusions yet, just thinking out loud.

Sorry, did not hook a tack up to it. All I can say is that it come on like a dry pipe from what I can tell. But it is no secret that a dry pipe makes better power. Maros used to run the R&D dry pipe.....and Malone has run several different dry pipes throughout the years. Most dry pipes work great, you just really have to spend the time to tune them to get them hoppin and running like a scalded dog.

That being said I don't think this pipe is just bolt on and go mod. I think you really need the right accessories to optimize the set up and get it working for you. Big bore lamey and stroker motor guys with tl, ect I see the pipe helping them but not sure about the regular OEM ported cylinder guys w/ stock elecronics.

Exactly what I expected. Massive amounts of cash can make ANYTHING run tight.

That pipe will need every aftermarket part under the sun to make it hit. Just like a 9.

Good reading though but B pipes and limited set ups still make more sense IMO.

Who runs stock electrics? You don't even have an Enhancer in it right now, correct?

Also, your cylinder has never made great bottom end either, so add on the stock cdi/flywheel and you just softened it more.

Want to try my Enhancer/light flywheel?

Sure, I will try your stuff in it. I just wanted to test the set up in different combinations, not throw everything at it at once one hope something sticks

 

[SuperJETT]

I've got to pull the electric box apart anyway and you already made me take the flywheel off, so it's easy enough to try them out.

Want to try my base gasket too?

You need to get tach on there and see where your at. Dry pipe rip but need the right combo of compression, timing, and pump work to make power where you want them. I've very curouis to see what your pulling up top.Good luck tuning:bananajump: and please post some numbers when you have them

I doubt many people including myself could keep his ski pinned on smooth water, it's a very squirrelly hull and his lamey pv cylinder seems to be more ported for top end (probably an old race cylinder) plus the dry pipe.

Well, a race port job with high compression & a good timing curve should have plenty of bottom end:shhh:
Come on how hard is it to crouch down, pull the throttle & hold on:nana:

You said timing curve, right now he's got a stock cdi in it, which will also kill the rpms so a tach reading won't show much.

I've ridden some fast skis before, but his is just super squirrelly.

any updates hunter?
