Another boat motor...

[Captain Slow]

that'll be what those little turbos are for , initial punch to get everything moving , then those big fucks take over and the skiers arms are no longer in their sockets.

[JabberWocky]

most run 2 speed automatics on them now to get them out of the water faster

Orly? Seriously though, that's interesting to note. I've never heard of it.

Shes got a powerglide?

[GTSBoy]

Why the horrible bend in the inlet runners? Surely that could have been a lot closer to vertical in the top section and give better flow properties? The way it is, the flow will crowd the outside of the bend and land in the bottom of the port.

Shes got a powerglide?

t400 from memory, with no converter, just straight off the back of the motor, and only use 2nd and 3rd gears,

[edo]

It has a 2 speed transmission...yes.

The key is to make the power seamless...it has to be a constant force for accelerating out of the hole or even out of tighter corners. A sudden hit from monster turbos just pulls the skiers over the front.
If my photos werent alarmingly pox you might notice that the big turbos also have a bleed off to the small ones to ensure they are working constantly...just to keep it smooth.

GTSBoy, youre making monster assumptions on all sorts of things that you cant see. Literally hundreads of hours on an engine dyno after all the modelling have pretty much decided that this design works best.

Oh, Its Simons own boat, its a 21foot Force with that big leg out the back. The aim is to wina ski race & then drag his 5 & 6 year old kids around on knee boards etc afterwards at 20mph...just to prove how user friendly it is.

Its still getting mufflers & water cooled manifolds so these skiers might not end up showered in fuel/smoke/crap like most of the others

[Smashed S15 Bloke]

are there really enough plumbers/landscapers/trucking magnates and drug barons in the australian ski boat scene with enough resources to throw down 200 large for a boat motor?

p.s. simon is a nissan god/guru, not shitcanning him and i love that motor, but geeze at half a house, is there a market for these things?

[edo]

Considering most of the top boats use 3 or 4 engines a year, they are already spending that much...& the Yanks are the big market...bloody kiwis too!

[Roadsailing]

looks good!

learn to use your camerrra fone!

far canal.

there HAS to be a market for atmo ones with that intake manifold for shoe-horning into S15's :D

[edo]

you wouldnt be able to see over that manifold

[Smashed S15 Bloke]

you wouldnt be able to see over that manifold

yeah that's the point of the exercise :D

[Smashed S15 Bloke]

woo hoo



satisfies my Nissan fetish and my "bogan at heart, grew up loving holden v8's attitude" :D

[Jason Broadhurst]

Won't go far without a prop

[Smashed S15 Bloke]

Won't go far without a prop

nah bro, I'm only gunna drive it on land.




































:D yes I know youre talking about the boat. but dont them ski boat guys keep their prop specs in a vault at home next to nuclear missile silo launch codes?

TOP SECRET style.
