Solas Testing With V-Tech 402 Program
I thought I would post up some of my testing information after I removed the flame arrestor and installed a Solas impeller and Riva wear ring since there seems to be a lot of misleading information out there.
First, I did some testing after I removed the stock flame arrestor and I didn't notice any significant performance difference. So I wouldn't recommend removing the stock flame arrestor unless you are installing an aftermarket intake.
So here is my baseline information I posted before:
V-Tech 402 Program Sport Average
5-15 mph: 0.64
5-25 mph: 1.28
5-35 mph: 2.12
5-45 mph: 3.75
5-50 mph: 6.15
Top Speed: 51.60 mph
Here is after I removed the stock flame arrestor and installed the Solas impeller and Riva wear ring:
V-Tech 402 Program FA Removed Solas Impeller Riva Wear Ring Sport Average
5-15 mph: 0.58
5-25 mph: 1.19
5-35 mph: 1.99
5-45 mph: 3.39
5-50 mph: 5.50
Top Speed: 51.50 mph
So the Solas impeller does make a difference. But I didn't notice any top speed difference that was claimed elsewhere.
Also the Solas impeller and Riva wear ring seemed to eliminate the cavitation I had when spinning the back end around and playing around.

It's really crazy the $ involved for little to no gain on these skis slowly giving up my hope on getting it to the 55-60mph range without going crazy and getting the turbo kit. If only someone would make a turbo/supercharger kit at a cheaper price point. I had hopes with the Solas and a tune to get it to atleast 53-55 mph range. Think we need more top end especially with these bigger props to see it's full potential.
I'm surprised there was little difference in acceleration ... I don't care about top speed
I agree acceleration > top speed.
I don't get the desire for top speed. I find it hard to believe that getting another 4-5mph out of a spark is going to make it that much more fun. Depending on rider and water conditions, my sparks top out at 49-51. I can't tell the difference between 49-51, so why would I spend a ton to get it to 55?
I don't ride with other guys on big skis, I have 2 sparks, and play on small lakes whipping 180s, catching air off my own wake, etc. I find they are most playful between 25-35 anyway. For me it is all about the sweet spot in the power band. I only go above 40 when I am running across the lake and I need to get on top of the chop, as it stabilizes a little more at 45 when the lake is choppy. Other than that, I'm riding around working on getting my tail slides more consistently executed.

Sometimes I think it is just chasing a number instead of the actual fun you are having on the SeaDoo. I don't know why people think a turbo-kit would be cheap. Companies want to make money, an if you want a big boost in speed, then you are going to have to pay for it. I will say that I think it might be better to just buy a higher powered PWC in the first place instead of buying the Spark and then upgrading it.
Are you maxing your RPMs at top speed?
Yup. Agreed. Unless you are racing them, I don't see what 3-4 more MPH will really do on the fun meter.Sometimes I think it is just chasing a number instead of the actual fun you are having on the SeaDoo.
thanks for the write up. I guess in the end with the amount of money spent its not a change that would be noticed much. Unless other with it can convince us otherwise.
I was pulling 7800-7900 rpm with the V-Tech 402 program, flame arrestor removed, Solas impeller and Riva wear ring.
Look at comparisons through the years-
1- Mid nineties XP 110 HP Average about 57 Stock!
2-Later Nineties XP-L Shock seat 130 HP= 61-62 Stock
3- Supercharged Skies From 185-260 HP = 62 - 69 Stock.
If you bought the Spark for top speed You Brought The "Wrong Girl to the Dance?"
But 55 on the Spark would seem like 70 on my Ole RXT-X!

I'm not wanting miracles asking for 3-5mph to keep up with my buddies GTI atleast, when we go on long hauls.Look at comparisons through the years-

There are a Lot of us that would like that 3-5 MPH but I think BRP is going to be the one that gives us that because they can do it stock? (If they Want!)I'm not wanting miracles asking for 3-5mph to keep up with my buddies GTI atleast, when we go on long hauls.
The ski will do 55 mph but need to get right combo , just need to give it time ...
Prop and pump need to be replaced. Wondering why nobody has tried an extended ride plate as of yet ?
All the results I posted were with a full tank of fuel. I did this to help keep the nose down for the acceleration runs. I know I'd see some better top speed numbers with less fuel in the tank.
Best speed run with 1/4 tank and flaaaaaat water with snow flake rider ...
Your RPMs seem low. Full tank and (no offense intended) body weight are likely playing a large part in reducing your top speed.
So JoeZ, what RPM should I be turning? And since you think my body weight is playing affect into the top speed numbers I'm seeing, how much do you think I weigh?Your RPMs seem low. Full tank and (no offense intended) body weight are likely playing a large part in reducing your top speed.
The warmer the water and hotter the air the more the RPM suffers.So JoeZ, what RPM should I be turning? And since you think my body weight is playing affect into the top speed numbers I'm seeing, how much do you think I weigh?
I was 8080 in 60 degree water- Now with 76 degree water I am at 8030!
Humid air in the deep south can make it even worse!
