Title says it all, what would you guys like to see done. I could go both ways with this...whats your thoughts?
 
I say the 951 X4.

As a 720 in a standup is less than the 750's that are common and the 787 in one is basically a 3D.
 
+2 on the turbo charged, nitrous breathing, low flying, push your eyeballs back into your melon and yank your arms off 951 X4...
 
951 in a go-kart.

Why? It's a waste of time. You can use a snowmobile engine which is a better option already is liquid cooled, already and a clutch on it, already has a water pump, and they rev higher than an MPEM will allow on a ski. Good luck cooling a 951 on land.
 
sled motor in the x4 i allways thought it would be cool my 600 injected sled makes 120hp and by a long shot out revs my 800x4 so a 160hp 800 would be radicle randorf
 
I'm leaning towards a superjet with a 787. Now just to find a newer superjet hull in Michigan. Hint Hint anyone...
 
I vote for the grenade as dan calls them

LOL, you're correct


Do something that hasn't been done yet (yes the stand up has been done too but it's cool), stuff a 787 into a Spark or something completely different. Build an 1100 triple X4. Buy Nick J's Carbon GSX hull and build that.
 
All of you are wrong.

Turbo 900 ACE (from the Spark) in an X4 hull.

You wanna talk about stupid fast.
 
And the price of said 180 HP turbo spark engine?

A 951 with twin pipes makes 160 HP.

Obviously way more, but there a lot more advantages of the ACE. Powerband, reliability, torque, ease to tune, power, etc etc. The motor itself wouldn't be that expensive and if you can fab up your own turbo you are in business.

A turbo ACE could make 160hp without breaking a sweat.

And cool factor? A turbo 4 stroke X4....oh man....
 
A 951 in a Spark or a four stroke in an X4. For no other reason than I’d find it cool. And it’s not my money [emoji23]
 
Non-ski related, but similar. I did this a few years ago with a boat resto on another forum. I had two stacks of postits, wrote all the cool stuff in one colour, and the non-cool on another.
I ended up with a 16.5’ ski boat that can rip your face off. Sounds cool until you want to actually use it for anything. I’ve gone down so many prop sizes I might as well not have one.

Ive built them all! 787 hx is fun..951x4 twin pipe is fast. 787 carbon HXis too squirrly.. Triple cyl blaster is a hoot , the ATM carbon hull x4 787 SS is funnest and the carbon hull 300hp 4tec xpl is most terrifying and unsafest at 85 mph.

Hey you can always put it on a southbound train :blush:

There is a runner a couple states over that comes with a double trailer and beach cart. The guy is down to 2500 in PM's now if he would just give in and drive it to me lol.
