Fastest ? JS 550 jetski with tuned 850 sxr motor

[bkoche750]

I need some under hood pictures/video!

[Turbojeep23]

was this the break in run? it seems like you were breaking it in the way you kept varying the throttle.

[foximus]

JetGran. You have a build album of this? Id like to compare yours vs mine. And also need more vids. I just put a big hub TBM pump in mine... can barely keep it in the water when you crack open the throttle. Did a top speed run of 50mph against the stock rev limiter the entire time. Need something steeper than the low pitch 9/17 for a faster run.

[JETGRAN]

No album yet mate, vid's soon ! Going to play next week end ;-) !!!

[metaldeth83]

That thing must get squirly at WOT. my 550/650 conversion does then, I cant imagine the speed of that one!

[hfurll]

all that work and you left the air hole in the front of the hood???????????

still thumbs up!!!!!!

[89kawa]

what did you do about the hole in the hoos when you sub mine fills upp

[Episcleritis]

Crazass brits.

[Episcleritis]

Sounds nice.

How the hell did you get it to fit?

[JETGRAN]

Good question lol...you just keep going till it does.....Once youve started...

[JIMRAW]

Why bother putting an 850 engine in a 550 hull if all your going to do is piss about. Get the thing filmed while the throttle is pinned wide open. Lets see what this 850 can do

[JETGRAN]

I will, That was the first test day

[JIMRAW]

Have you given this ski some WOT yet??? If so, please post the video on here some we can have a look. I'm really interested to see how this thing goes

[JETGRAN]

I will when it isnt -6 C. Not long till summer

[JIMRAW]

Nice one - I can't wait to see this thing go. Roll on summer

[MarkalGomez]

[MarkalGomez]

That is Awesome! I've always wanted to put a 750 motor into a 550 hull. they just feel better the 550's i reckon

[zagi404]

do you have any pictures of the inside i want to see how the 800 motor fits in the 550

[sports2max]

damn you put a shit load of work into this thing just so you could say you could

[JETGRAN]

I did it cos I like 550's ! The origional motor ran out of power with all the mods possible, I could have got a superjet but I would have spent as much tuning that as I have on this.

[sports2max]

how is an sxr pump compatible with a 550 hull...but thats crazy if it works

[JETGRAN]

I took a mould of an sxr back end and grafted it into the 550 hull.

[sports2max]

why would you ever want to do that the sxr engine doesnt work well with a 550 pump

[JETGRAN]

It has an SXR pump !
