Dual hairdryers.

[NMCB4SEABEE]

too bad u can only move so much water through the outdrive

[marcuskicker]

engine specs???? compression ratio and boost??? and can you run regular gas????

[chevy17hmr]

if mad max needed to patrol the water, I found him a boat.

[delco2242]

you drive like a bitch

[OceanStateTuning]

@delco2242 Thank you

[robbewuzhere]

@delco2242 You comment like a fag

[luuks1609]

thumbs up if you're bored and typed: Worlds Fastest Boat

[OceanStateTuning]

@luuks1609 Ha this is far from

[jdubcbr600]

Did you make the Edelbrock blow through and did you make the carb hat ?

[OceanStateTuning]

@jdubcbr600 Yes and Yes, although I would not use the Edelbrock for a blow through if you have Holley's available. All I did too the Edelbrock was put .110 needle and seat in it, a bigger accellerator pump and then Jet it for the fuel it needed (I had to drill the Jets VERY large) it worked and the AFR's were fine but it was only 4-5lbs... I hear after like 6psi you risk collapsing the float as they are cheap.

[OceanStateTuning]

@jdubcbr600 For the fuel pump I hammered in some barb fittings to the atmospheric ports on the pump and hooked it up to boost referance so it would act as a 1:1 rising rate

[OceanStateTuning]

@jdubcbr600 For the carb hat I took a aircleaner base plate and welded a Salad bowl from Christmas tree shop to the top of it then took a couple of 45* bends and welded them into it. It worked!

@OceanStateTuning

That is onto it as!!

[MeyagiTuned]

Oh it was fun building this

[Burgeezy]

Where did you get the turbos and still manage to keep it under a grand invested? I am curious because I'm wanting to build me a jet boat too, but I am also on a tight budget.

[OceanStateTuning]

@Burgeezy 80's Saab 900's $25 each from junk yard

[Burgeezy]

@OceanStateTuning Awesome thanks for the reply. Do you know what kind of PSI you are running with that setup?

[OceanStateTuning]

@Burgeezy Just using the stock Saab Wastegates so it was 4-5 PSI

[117nathanmyers]

you should get some air filters. if you want to get something in your turbo then your engine be my guest.

[OceanStateTuning]

@117nathanmyers No thank you

[6speeddakota]

redneck ingenuity at its finest, great job man

[craigsmithx]

wow, what a monster

[OceanStateTuning]

@craigsmithx She is fun for having less then a grand into the whole project

[djbadandy1]

idc how ghetto you can call it, it does the job it looks like :))

a bud of mine god rest him, had a 468 olds powered jet boat

that we had mucho good times in...

[TheLordofShell]

And then a girl's earring gets loose...

[30GB]

rofl 2 different turbos and a salad bowl for the collector

[palahniukpaul]

Is that bowl on top of the carb?!!

[OceanStateTuning]

@palahniukpaul Salad bowl from x mas tree store

[xbfalcon351coupe]

@OceanStateTuning AWESOME!!!!! I LOVE homebuilt engineering like that!!! Anyone with a fat wallet can walk into a speedshop; I LOVE inventive solutions - well done!

[cdude100]

can you say king champ of the poker run

[108Automotive]

blow through carb setup or is it tbi?

[OceanStateTuning]

@108Automotive ghetto blow through using an edelbrock

[spannerpro]

@OceanStateTuning Gotta love ghetto Great work shows theres still crafty people round keep up the good work

[thercpoop]

hair dryers!

[mangler0075]

@willbaguley9000

You obviously have no idea what your talking about..

[OceanStateTuning]

@willbaguley9000 why

[oaeproductions]

@OceanStateTuning its a bad choice because the turbo can easily suck water into the engine.....

[OceanStateTuning]

@oaeproductions And why is that a bad choice? Water will do what harm? If it sucks in enough to hydrolock the engine then the boat has SUNK, And as for mists of water, do some water injection research - its not a bad thing.

[oaeproductions]

@OceanStateTuning as far as im conserned.....ANY water getting into a turbo is not good.....

[OceanStateTuning]

@oaeproductions The only damage water getting into a turbo can cause is wear on the tips of the compressor wheel but that will only happen after a longgggg time of hitting water, something like this that only sees 20min rides or so a half dozen times a summer will never show any erosion.

[huskydriver125]

nice!

[OceanStateTuning]

Wow can't believe over 100,000 views and it's not even a funny video lol

[b20mr2]

good stuf man but i think your maxing those t28s out at low rpm ,, your exhaust pressure is too high for that frame ... did you upgrade yet ?

[OceanStateTuning]

@b20mr2 Actually little T3's... I know they are way to small, I had one laying around and I traded a cat converter to a junk yard for the second one... boat made a TON of torque, would of been a great setup for a truck. Boat I am sure is scrapped by now, I sold it and the guy took the motor out and put it in a C10 and the boat (pos, VERY HEAVY fiberglass over wood boat) went somewhere else.

[b20mr2]

good stuf man but i fthink your maxing those t28s out at low rpm ,, your exhaust pressure is too high for that frame ... did you upgrade yet ?

[OceanStateTuning]

@b20mr2 I got rid of the boat shortly after this, but yeah they were probably maxed out by 4000rpms or so... they were T3's though .42 cold / .48 hot

[1oakst]

wack the boost right up

[swat2400]

would go well until ya got water in ya turbos

[OceanStateTuning]

@swat2400 What is wrong with that?

[kimmer6]

Cool project. Much better garage engineering than pissing money away on store bought parts. Now you know something about turbos that books can't really tell you.

Try adding a Pontiac pressure/vacuum advancer and dial in pressure retard and it will blow the lid right off your salad bowl.

[Courage68]

i loled so hard at the salad bowl carb hat.. but it seems to work great !

[tubesteakdynamo]

Actually there could be an advantage to adding boost to a boat if you increase the size of the prop/impeller. A 5 inch prop moving at 4000 RPM will move the boat at the same speed whether it has 1000 HP or 100. The only way boost will help you on the water would be to up the size of the prop so you can move more water with that extra power, otherwise boost means bugger all in the water.

[hondarideralex]

@tubesteakdynamo "Actually there could be an advantage.." HOLY CRAP!!! it makes more horsepower!!!! that is exactly why you would want to have more power! yes you are right, about the 5" prop, to a degree. You could have the same diameter prop with a vastly different pitch. the point of increasing horsepower is so that you can run a more aggressive prop or impeller in this case that the 100 hp motor wouldn't be able to turn it because it is too aggressive.

[OceanStateTuning]

@tubesteakdynamo It really needed a different size impeller but It did not matter because the boat itself could not handle the speed it went to begin with, the hull was VERY unsafe and HEAVY!!! I sold the boat to a friend who yanked the motor out and put it in his C10

[joedrummer2010]

@tubesteakdynamo There would also be an advantage in ditching that stupid jet pump in favor of a propeller out-drive. Jet pumps are inefficient and you'd be better off with a prop that will actually move some water instead of wasting half your horsepower..... not trying to be a dick, just being honest......

[harmongreer]

how much boost you making?

[OceanStateTuning]

@harmongreer 5psi

[Lawsonsvideos702]

lol junk yard set up.. It works.

[s04r3r]

ahh...I see you bought the salad bowl that comes with the built in BOV. nice =)

[Blown4banger]

Wow, that motor looks weird without the water pump on the front. lol

[krnz3]

Very nice for a junkyard turbo setup. Do you have a write up on how you did it?

[OceanStateTuning]

@krnz3 Just look at it lol... two block hugger headers flipped upside down with t3 flanges welded to the collectors. two Saab 900 .42/.48 turbos going into a salad bowl welded to the bottom half of a edelbrock air filter base. Pressurized the vent tubes on the fuel pump so it raises fuel pressure. I ran my wideband on it to tune it and I just drilled the Jets out because the biggest Edel. jets and smallest metering rods it was still too lean. Very simple, worked great for only a few hundred.

[usnavyseals99]

damn dude how u get a turbo for only $25 like mine for my cummins was $3200 ..and if it ate a bird it would be badass lol

[OceanStateTuning]

@usnavyseals99 If you look at the setup it is just stuff I had laying around. One turbo came from a pull a part junk yard for $25 the other one i just traded them a junk cat converter for... They are off Saab 900's

[usnavyseals99]

no filters?? ur either rich or fucking stupid

[OceanStateTuning]

@usnavyseals99 I got money, this was a cheap setup BUT When you are on the water you do not have a dust/dirt issue. Most boats do not run air filters... If it eats a bird oh well its a $25 turbo

[h8wrxs]

@OceanStateTuning yeah but you do have the issue of it sucking in water. still not a bad setup.

[OceanStateTuning]

@h8wrxs You need to suck in a lot of water to hydro lock. If anything a mist would actually help this (water injection) but it is very dry on the boat.

[RikterZilla]

Cool.

[JJCutlass]

Who cares about budget.....effort here is off the meter!

[BigBoostGT]

Bad ass! I was just looking at getting a jet boat and putting a twin turbo set up on it. SBF though.

[tubesteakdynamo]

@BigBoostGT < Just as long as you realize turbo means nothing on the water. There's no gravity for the tires to overcome so the engine is at full RPM in a split second and if the engine is at full RPM then the impeller is at full RPM. Since there's no tires dragging on the motor, there's No need for boost except to look badass and make noise. Don't get me wrong, it's badass and I want it on MY boat but there really is no gain.

[chopperkeith]

@tubesteakdynamo Are you stonned?

[tubesteakdynamo]

@chopperkeith What the fuck is "stonned"? Are you asking if I'm stoned?

[hondarideralex]

@tubesteakdynamo do you understand the point of forced induction at all?! turbo charging and supercharging increase horsepower!!! you can run more pitch which puts more load because you are pushing more water per revolution which takes more torque and horsepower.

[utubey]

Im gonna hunt you down and check this thing out. You make Rhode Island PROUD! One thing, you can easily get the AFR right with an AFPR that gets static pressure from the turbo to match fuel PSI. Too bad I tossed one out a month ago, or you could have had yet another low budget part! Keep up the great work!

[KZ1300Rider]

This is just constructive criticism so don't take it wrong. You need to box the carb. Trying to blow through a carb is a bad idea you can back flow the fuel through the jets and lean out the motor. Carbs work on pressure differences and if you pressurise the entire carb they work better than blowing through them.

[bridgy7]

unless his had  the carby set up for boost!!

[no911x]

if he didnt it wouldnt run above atmospheric...

[linadsenoj]

many Carbs have the float bleed air by the barrels. So as long as you seal it right your float chamber will be getting the same pressure as what is in your charge pipes.

[AndrewEG]

or you can just pressurise the float bowls with boosted air like he's done

[pancakepie2]

very nice

[OceanStateTuning]

I am running just a off the shelf 1405 Edelbrock carb. I went to .110 needle and seats, and had to go HUGE on the Jets and play with the metering rods/step up springs to get the AFR good. I had to boost referenced the fuel pump to keep the fuel from being pushed out. I run 5psi right now, This setup I bet would work for anything under 10, after that you would want a better fuel system, some sort of solid floats, and a intercooler :)

[justrem307]

did you have to upgrade the carb? what do you use for a vacuum port? about how much boost does it run? I'm looking to build my own thanks

[OceanStateTuning]

small ones from 89 saab 900's they are .42/.48 t3's

[jimbrayhunter]

what turbos are you using

[OceanStateTuning]

edel 600cfm.... 1405

[buzzznjohn]

what carb have you got

[sillydillydokieo]

air filters may be wise....
