supercharger qeuestion
 

Iam lookooking at vortech unit to put on a 95 502 mpi its off of a newer motor with serpentine belts. So my question is besides fuel system upgrades what else am I looking at. Has anyone put one of these in a 24 fountain cs? Low boost I want to ease I to this if possible.

Tough crowd here.

24 cs
 

Any one else here own one of these rare boats.? Trying to find out anything about it is like pulling hens teeth

You will also need a new computer or remap of the current computer. I would stay away from putting a car kit on a marine motor. If you are going to buy a Vortech then make sure it's the compete tuned marine kit.

That being said I would personally recommend staying away from the centrifugal Superchargers like Vortech or Pro Charger. Whipple is the way to go. I had a 98 502 with a Whipple and it was amazing and ran over 600hrs. You might be able to find a old side mount used Whipple system or just go with a new complete kit with intercooler and new intake.

Dont listen^^^^^ their are plenty of guys out their running centrifugal superchargers with hundreds of hours..what i like about them is hey are easier on the hole shot(drive) and your not in boost when cruising @ 3200 rpms or so.which keeps you from sucking down fuel.look up mark boos at precision marine,,he is the guy that will tune your ecm for you for a fee..

It is tuned for a marine motor, just a newer version model than mine. I'll have to upgrade to mefi 3 harness to match up the programming.

Thanks I'm not looking to to max out my engine yet but more is better, right? Like I said earlier I am easing into this so I can go boating not broke. Now later I'm not sure, speed is addictive!

not necessarily true, internet talk. My vortech is in vacuum until over 4000 RPM, just like my buddies with similar set up whipple. The power curve on a dyno is nearly identical. There are so many experts on here about centrifugal SC's, yet no one has one.

There is a dude out here in Seattle with a CS and a pro charger. Pretty sure Mark Boos did his ecm.

LOL no way a centrifugal super charger is more efficient then a Whipple screw. My SBC Whipple charged motors ran in vacuum most of the time while cruising. I was not saying you won't like the vortech or that they are junk, just giving my opinion about what I would do if I wanted to put a SC on a 502.

If you get a deal in the marine Vortech and its in good shape then go for it. Or if you already have it then you will love it. Any Supercharger is better then none :-)

Commandersander summed up the mods you will need. The Harness should not be a big deal.

Didn't say anything about efficiency… My 540 Vortech motor is in vacuum til 4100 rpm, I cruise at 60-62 mph like that.

Thanks again, I'm starting to learn a lot here. Yes I think its a good deal but I want to make sure its right . More power is good, too much is broken bravo or toasted engine.

OK so you are saying your motor is in vacuum under 4100rpm regress of throttle position or load? Wow thats one good supercharger system you have if it can't create boost under 4100rpm... enter sarcasm icon here.

I was simply giving my personal opinion since maybe he was looking at buying a Vortech, He seemed new and was asking questions about a supercharger for a 502. If nobody mentioned other options or opinions then what use is this forum? Why are all you Vortech, Procharger guys so sensitive?

MP

Warning!! Buying a Vortech or Pro-Charger may make you defensive and sensitive. LOL

These systems are good for the money and if the deals right and you can't swing a Whipple then I say go for it. But you need to know what the trade offs are before you make the purchase. When I was researching supercharges for my 502 I ended up going with Whipple. I seriously looked at Pro-charger and thought the Whipple seemed like the better choice. That was back in 98 and I have only bought Whipple since.

There are very few centrifugal supercharges being used for many reasons. That does not mean that they are bad, its just that there are better solutions.

Mark Boos can map any SC and you don't see him selling many Pro-Chargers. He has done them all and his choice is Whipple.

I have a vortech and responded in a thread about a guy asking about a vortech, I have no idea why your sweatin me on it. Insert sarcasm where ever you like.

I was referring to 4000 rpm unloaded cruise in vacuum since that's what your reply said. Seeing how much boost you can make in a "holeshot" is why people blow bravos and then scratch their head as to why.

Buy any super charger you want, I could care less. I just see over and over that this SC does this and this SC does that, and more often than not the information isn't accurate..

I have a 3.3 whipple now, my 500 Vortech kit is for sale in the swap forum.

From what I`ve seen a Roots type blower is the way to go .. them centrifugals seems to be quite a pain in the AZZ

Please post pics of your setup when it's done. I need some encouragement. :)

I had a set of 500efi's in a 01 35 Fountain and put the Vortech marine kit on it and had EB Marine install and do the tune on the dyno. They made about 800hp and ran great for about 200 hours I just couldn't keep drives on the boat. The next owner built a set of 555 CI lowers and used the same blowers and made almost 1100HP!! He is still running them. He ran that boat 118 in the LOTO Shootout a couple years ago with SCX drives. It was honestly all about the tune and Eric at EB did a great job tuning the motors and they were solid. The best thing IMO about the way we did it was we tuned the motors on the dyno then put them in the boat and did some additional fine adjustments.

no,the screw blowers are the way to go,whipple or psi although turbo charging is quickly coming into play.soon roots blowers will be a thing of the past imo.

Ohhhh soooo true.

Turbo....
No load on the crank
Easier to maintain over time
Cheaper
Variable ecu mapping
Lower octane friendly (corn fuel)

The only real significant drawback is egt....but very manageable.

I have an xtrim in my mustang efi, whipple in my lightning efi, b&m 250's on the twin carb'd Merlin's, turbos on the 2nd gen rx7 efi, and a miniature centrifugal on the rc boat..na

The rx7 requires the least amount of attention.

.02

Soon as I can figure out how to upload one I will

small vortech on 502
 

Here is what it will look like when you are done.
Fyi, it is designed system for late model 502.
Guessing it runs around 3 lbs.
No injector upgrade required.
No fuel upgrade other than that additional Carter electric pump added.
Comes with modified ecu.
You can even use stock exhaust
Easiest 125-135hp you can add.
Fits under most engine covers
Easy to rebuild when needed.
It has it's place and meets requirements as does Whipple

Damn, that's a fine looking setup.

It's for sale!

Sorry buck35, that was bad form. You have first dibs. We will figure out the older to newer 502mpi issue.
So it's really not for sale until u say u don't want to pursue anymore.
Talk to you when u get back from vacation
Larry

Had me wondering for a minute, I'm still on board. Whats the secret of pics that is eluding me

Not sure what u are asking? Posting of pictures?
You need to become a member. Don't spend too much money on ur vacation!
Looks like there are some options on the mefi 1 to mefi3 harness.
Looks like we have most everything covered on the serpentine upgrade except the water pump.
You will go to the aeromotive fuel pump an regulator plus return to tank.
Add sea strainer and I think we will have everything covered.
Larry

Pretty much a beach bum, beer gets expensive though lol. I'll check membership lots of good people here!

[ATTACH=CONFIG]515781[/ATTACH hopefully that worked

That's a super sweet looking boat, love the colors. It will be super fast with a supercharged 502. Hopefully you have good steering.

MP

Yes it has lovorsi dual hydraulic. Its got most of the goodies all ready on it

Oops lathem steering, just out crawling around looks like fuel return not so easy they started with a tank and turned it into a boat

Buck, Whipple has a set up if you cant return to the tank you can run the excess through a fuel cooler back into the main line before the water separator, I would think it would be the same for the other SCs, I'm sure someone will post more about it...

everyone is screaming whipple!! go a head cut a hole for the scoop and then good luck finding a blackhawk case when that drive exploads..just being a smart azz but it will happen..the lower in that drive wont handle the weight and the lower grunt power the engine will be putting out..

just my o2..

Its got a bravo 1 on it blackhawk is paint scheme only I assume

I'm just gonna put this out there. Since the Whipples are "so efficient" why is it that they don't make as much horsepower on pump gas as a Procharger?

I have a 96 24cs with a pro charger. I had to remote mount the intercooler and it is very tight with the belt up against the bulkhead. I used an aeromtive A1000 pump and return to the tank. Mark Boos calibrated my ECM when I had a mefi 1 and I just upgraded to a mefi 3 and he did that one to. Boat runs great and idles great. Went from about 72mph top speed to about 82. Its a good set up for me, running 5-6lbs of boost. Fits under my stock sunpad and thats what mattered to the wife. Im running the stock B1 with a labbed 30.

Yeah and from what I have seen the Hotties like the roots style as well

Thats a cool looking boat !

I know Whipples and turbos are better and more efficiant but I like to look at sh!t and I just like the look of a motor w Roots blowers and they Have a distinct whine I like. Maybe I am too old school but the way a motor looks make me happy. I'm goin a hunderd w my deal . that's good enough. ( 95 with 6 chicks and 3 coolers full of beer!) :D
