flywheel question

[waxhead]

That will never happen, There isn't enough differance.


Now, I just recieved the new WAX charging ignition........................
I have to hand it to him, very nice job with this.

I'm playing with curves & such. It has way more tunability than the Vilder & factory fire. I have a feeling this will be the Sh*# !

the dyno will be running soon!! Updates tomorrow!!

Awesome glad it got there Paul
Will be interested to know what your testing comes back like

well, chalk that one up to lesson learned...the HARD way. With my 62t I natrually figured I needed 62t flywheel...which would've been ok until I spoke with Paul and realized I'm runnin a 61x stator! You know what the local dealer can do with their 20% restocking fee fro the wrong f/w!

:rant: 'effin ram it!:cussing:

Barnies wants 20%? that is effed up. that's a lot of jack for putting a part back on a shelf.

:drillsergeant: C'mon TIM! GET WITH THE PROGRAM! There's A lot of work entailed


with that sorta shizz! EVERYONE knows that!

The extra turbulence caused by the open magnets provides increased cooling to the stator, and cooler wire has lower resistance, which generates more current/voltage, which equals a hotter spark! There! Lighter and hotter spark from a 61x flywheel/stator, proven.

:firedevil: :bs2: Well I think we ought to install a liquid nitrogen tank and run some cooling lines down to the stator coil area and cool that baby down to get the resistance down and the voltage up. :bs2: :firedevil:

how do you tell the diff between a T and X stator?

 

[keefer]

There are 2 differant train of thoughts with what happens with the differant flywheels. I'll explain the differances first

61x has a smaller dia stator/magnets. The magnets are exposed, it is physicly 1/2 pound lighter than a T flywheel. Is easily identified by the magnets & the D shaped hole in the front.

62t Larger in Dia Stator/ magnets. Magnets are embedded, it's heavier.
identified by enclosed magnets & round holes in the front.

Both flywheels can be lightened by .5-.6 tenths of a pound (safely)

A lot of people opt to have X flywheels reather than T's because of weight. & then cut them lighter. Others opt for the T because they sight the "windage" from the X magnets , counter affects the lighter quality of the flywheel. Both stators are adaptable to the electrics & need to be run with their counterpart flywheel ( no mixing & matching).

In FS boats, The X is my choice for the weight differance. I have not seen a differance in the windage theory. overall, use what you have. the slight weight differance doesn't make a big enough differance to over come the cost factor.

ski ya, Paul

I had a one of each out a few months ago and measured them but did not write it down. I do not remember if there was a different number or something on them.. I bet Paul knows some way of identifying them.

how do you tell the diff between a T and X stator?

The od of a 61X stator is 95.5mm and 62T is 103.5mm. The 61X flywheel weighs 3.610 lb and 62T is 3.7436 lb. The outside diameter of both flywheels are the same. The 61X needs a smaller stator because of the thicker magnets.

 

[robertg]

I just weighed my lightened 62T flywheel, it is 3.3566 lb. So it is 0.2 lb lighter than the stock one.

 

[robertg]

I figured I would add this. I just bought a 62T Riva lightened flywheel and it weighs 2.042 lb. Does anyone know what a MSD TL flywheel weighs?

 

[SUPERJET-113]

1.8 lb. i think

hi this might be an old thread but I would like to know if you use stick 62t cdi with 61x fw/stator? the reason I asked is my ski is now set up this way but with stock 62t cdi and it hits rev limit a lot.

Do you have an a/m exhaust like a Factory Pipe? It is easy to hit the rev limit on any stock CDI 61x or 62t with a pipe installed.

Yes you can run a 62t cdi on a 61x fw and stator. I ran the same exact setup on a built out 760 and had zero issues w a bpipe but I never kept the ski in the water.

Hi yes my ski has factory type4 dry pipe, ada head, atp waterbox, dual 46 mm buckshots and 62t cylinder with 85 mm forged pistons.

Did you have to adjust the timing when you installed it? I dont know if timing mark on the 61x case is the same as 62t case. becasue I took the 61x fw stator combo out of 61 x case and my 62t case timing mark was deleted.

Recommend modded rev limit or better a MSD enhancer or Zeel CDI which have higher rev limits and better timing curves for performance and also to help avoid detonation at higher RPMs.

Hi thanks a lot jet, I have both modded rev limit cdi and 62t zeeltronic on order. For now I just wanna make sure everything is ok and my ski hit rev limit is from using stock(no rev limiter) cdi.

Another cause of cavitation is an airleak at your pump to pump shoe seal.

Thanks Jet, when I installed the 61x ststor and flywheel on my ski's 62t case, I just use the mark on the case , is this correct? Or do I need to use the timing light to find the mark? If timimg is way off, may that be the cause of hitting the rev limit?
