What supercharger are you running on your boat that is controlled by a switch? not saying isn’t possible but I never heard of such I’ve been around quite a few supercharged boats and it’s not one of those things you just flip a switch and turn off.I have a supercharged jetski, the bottom end is amazing, but the boost is revalant to the throttle, it's always adding boost and can be hard on fuel, I wish I had the option to turn my charger off for those days that I just wanna tour around in the heat.
My boat has a supercharger and it can be shut off via a switch but the bottom end tottaly sucks without the boost.
I have a Diesel powered Volvo kad44, supercharged and turbo charged.What supercharger are you running on your boat that is controlled by a switch? not saying isn’t possible but I never heard of such I’ve been around quite a few supercharged boats and it’s not one of those things you just flip a switch and turn off.
The heat exchanger on the Procharged Axys is under the tunnel, to install it you need to remove the gas tank. It uses an auxiliary water pump as well. Our Jet ski has a supercharger as well and pulls tubes better than our boat lol, but at 250hp it does like the gas. Not sure who likes the jet ski better, my kids or the local gas stationI don't know where they are mounting the heat exchanger for the intercooler system on the Polaris kits, but on the Cats it is on the bottom of the bulkhead under the motor. So if early season rock and stump bashing is your thing it is susceptible to damage. Since they are building boost all the time they always require extra fuel so they can be thirsty. Friend has one on his Alpha and If he wants to make it over 45 miles he needs to pack extra fuel. After riding his it would be the only way I'd go if I were boosting a sled.
Value wise they don't have very good gains for the price at sea level lower altitudes, but the higher altitude kits are running great on just pump gas.
Hey Motorbreath, I should clarify, this was from what Kevin at Speedwerx said. They have excellent gains at elevation but are running such low boost at low elevation with their current tune that the value for the gains is not there if your only ride sea level, which is the same for the turbos. My friends with turbos that ride here in Upper MI don't have much for gains for the same reason, but work "well" out west.Why is this? Shouldn't the boost be relative to the pulley you use?
I guess they are focusing on pump gas tunes.Hey Motorbreath, I should clarify, this was from what Kevin at Speedwerx said.

I ran one on a cat a few years back.
Ran clean and bottom end response was good but don’t expect the power/track speed of a turbo. The SC take power to make power and takes a lot to turn it seemed to rev a little slower then my turbos I think honestly they are making track speed and starting to pull at about the same time.
Will be another option for a SC soon that’s much more affordable price for many people the speed Werx is pretty expensive kit
Thanks for the reply @andrew90
So Let's say my turbo creates 220 Motor HP and the SC kit also creates 220 Motor HP, the actual result will yield less of an actual output (track speed?)?? That seems to make sense since the SC is pulling power to make it run but I would love to know how much less efficient it is!!! In other words if the SC kit allows the motor to create 220 HP how much motor HP does the turbod sled have to create to be roughly equivalent. Is it only 190 HP(maybe just maybe the turbo kits are creating as much as 190 HP on pump gas but I doubt it!!) or is it more like 215 HP from the turbo to create the same track speed/efficiency. If it's a big difference between those 2 AND if the low end isn't actually much improved by the SC compared to the turbo than it's not really worth the expense. However, if the difference in Motor HP to get the same actual result is negligible than it seems to make total sense.
To compare a base level turbo kit and the cost of it to the SC kit is like comparing apples to oranges. You simply get more with the SC kit in material alone. When you look at the Boondocker Agility kit with the intercooler the cost is $6,100. The cost for the SC kit is $6,750. If the difference in actual output is marginal between the 2, than it's debatable whether it's worth it or not. But if there's a big improvement, especially on the low end performance, and you get a lot more HP on the top end with the SC kit while on Pump Gas than it seems that it's totally worth it.
Of course, this assumes that each kit is dialed in and especially the fuel mapping is right, which seems to be the toughest thing to figure out for the aftermarket world... thus the reason for my earlier post looking for real world experience from guys who have actually put some miles on with this kit specifically on a Polaris 850.

I would agree right until the end when you started to talk about Street outlaws and said a SC or blower will have more out of the hole lol with timing retard/ 2 step or N2O a turbo will come out of the hole with more boost then a SC. Turbos have 10 + psi on the line that’s why it’s always such a game when staging and trying to burn the other guy down on the converter
