Interesting what these guys are up to.

oooooooohhh myy gooooooood. 13 Psi boost at 8,000RPMs+. Wow. I hope that there are not many of those popping up in the near future...
That will prove to be some stiff competition----the key will be "how long will it run like that"??

You said it... "POP"... that's what will happen to the poor seadoos with that much boost!

13psi really isn't that much. Depending on how strong the various motor components are it could easily handle it.
Now the only things I am unsure about are the following:
-There's no ECU designed to pull a little timing at the higher boost levels
(whic is certainly a plus for engine life...doesn't need to be a lot but just
enough to take the "edge" off). The current crop of ecu's actually crank
it up some...
-They're using Les Cooke's supercharger stuff (which is supposedly pretty
good) but I wonder about the added strain on an allready weak link (the
They're accomplishing it through machining the supercharger housing and using a different "wheel" so they shouldn't actually be spinning more rpms just compressing almost another atmosphere...That requires a substantial amount of force to be sure...
Here's an even scarier thought for you guys...Les also offers a 15psi kit...
I don't know that they're going to be knocking on the 85+ door just yet but you 75mph guys may be needing to look over your shoulder real soon as I suspect there's going to be a number of these things in the upper 70's in the summertime...
Of course I'm going to sit back and let a couple of those guys test their motors durability on this one...

13 PSI is nothing. The stock engine/pistons can handle it with ease.

I wonder how much they could take before things went sour....
as long as their injectors could keep up with the extra demand for fuel it wouldnt burn up
crank failure/ broken rods
I believe an oem dodge neon engine would take about 15psi, correct me if im wrong
I had an eagle talon I use to be into, the engine was a tank, it could handle upwards of 30psi with stronger headbolts
