Centrifical Supercharger Sound !
 

Ok guys , It is time for my stupid question..
I am putting a Single 511" with an intercooled V-4 Vortech supercharger in my Saber. I know it will make really good power & run like a champ but my question is : How will it sound ideling at the dock ? I don't think I have ever heard a
really healthy centrifical in a boat. I wouldn't guess it would have much cam surge due to the carb enclosure. I know it depends on the cam ect.... ( I will be a bit on the moderate side due to the fact that it is a family cruiser.) But how much will it lope , will the cam still sound choppy ? how much will the supercharger whine ??? ect...ect.... Anybody with any centrifical videos feel free to post them !!!!

Re: Centrifical Supercharger Sound !
 

No pun intended but if sounds like a prochrger at the docks it will sound like chit.
We used to have to take the belts off the blowers to be able to hear a noisey lifter,etc...

If anything go whipple. :cool:

Re: Centrifical Supercharger Sound !
 

A properly built centrifugal motor idles smooth and almost sounds stock because you can run a cam around 230/240 and make really good power. My motor made 950hp on the dyno and idles at 700 rpm's,if it wasn't for the 5" tail pipes and slight ringing from the blower (which the engine cover muffles about 80% at idle) you wouldn't know my boat wasn't just another bone stocker. Do you want to make noise or do you want to go fast :evilb: ,you could run dry headers if you are really looking for a obnoxious idle,Smitty

Re: Centrifical Supercharger Sound !
 

Is EFI an option?

Re: Centrifical Supercharger Sound !
 

EFI is not an option, It has a carb enclosure & that is what I will use.

My exhaust will be mostly dry but not completly. I have stainless marine dry tail pipes for a bravo set up & I am pretty shure I will end up with a tranny so the they will have aprox. 12" added to them that will be mixed a little & if I still want them completly dry (which I probably won't) I can do that too.
I was mainly woundering about the blower whine & cam lope.
(Aticfriends) forgive my oversight but what setup are you running ?

Re: Centrifical Supercharger Sound !
 

I had Pro Charger Stage III, M3 in my HP500s, making 800+hp. They squealed like a pig at idle and whined quite loud at rpm. They made fantastic power but just beat the daylights out of the components, even with the large intercooler.

Re: Centrifical Supercharger Sound !
 

What components did they tear up?

Re: Centrifical Supercharger Sound !
 

Any videos out there ??????????????????

Re: Centrifical Supercharger Sound !
 

Melted valves and burned through head and block.
Another time, melted valves and burned through head, and piston
Another time, melted valves and burned through head
Another time, melted valves, and burned through head and block
Last time, melted spark plug, burned through piston
All this during the 2000 & 2001 summer seasons.

They squeled like a pig at idle.

They whined at rpm.

I will NEVER use them again.

Re: Centrifical Supercharger Sound !
 

Please don't lump Vortech blowers in with the Procharger kits that were sold to marine applications and failed. We make 800+HP with very little noise and only 7 psi. Gear design, impeller design, intercooler design and fuel delivery system are the reasons why. To make 800+HP with the Procharger design you have to spin the blower a lot faster, which makes even more noise and heat.

Don't make the mistake of using too much cam and get your carb done by someone who knows blowthrough. If you are using a carb enclosure then you will have to use a remote mount intercooler. Not what I would recommend but if you already have the intercooler use the least amount of elbows possible and make your tubing big with large radius turns.

At 800 HP the components you will be beating up will be the drive.

Re: Centrifical Supercharger Sound !
 

I am using the intercooler that I already have which is the Vortech unit. Yeah the drive is the part I worry about beating up. That is the main reason I don't have one yet. I am trying to get the $$ togather for a drive that I know will handle
the power & not break every few weeks. I would really like to see a konrad hanging off the back of it soon !!

Re: Centrifical Supercharger Sound !
 

Stock motor or a hopped up on....502 mag?> 500 EFI what was it?
What system and who did the install? was this an EFI set up or Carb? with this kind of damage I would like to know more.....

Re: Centrifical Supercharger Sound !
 

I am curious too as to the install & application.. We have had very good results with them and very few problems. I am sure you've heard of problems with all Mfg's units..

Many people have different opinions on the forced induction systems out there. It comes down to preference and application, Some people like chocolate & some like vanilla and some people like all the flavors.. :drink:

As far as the Prochargers They do have a whine, especially the M3 & larger units.. Some people like the whine.. In any case as a rule they have performed well for us & our customers.. If money is'nt object R-tech's intercoolers are pretty trick in design and can help give you an edge, but ATI's coolers do work well too.. An intercooled centrifugal supercharger usually has a cooler boost than a whipple or other blower, meaning safer boost & more power.. :) Jamie / Lakeside

Re: Centrifical Supercharger Sound !
 

I'm running a 540 w/m3sc procharger,afr heads,stainless marine hi tq 3's w/5 inch tails,highly modified 502 mpi intake,mild hyd roller cam spec'd by RMbuilder,63lb injectors st 70 psi,afr heads. the blower rings a little at iidle but you can't really hear it with hatch closed. At wfo its sorta shrieks like it has a turbine. I have hear nothing but problems from owners of ANY centrifugal blowing thru the carb,make sure you get professional advice/work done to your carb if your set on running it that way,Smitty

Re: Centrifical Supercharger Sound !
 

You either had the worst luck in the world,a terrible set-up,incompetent mechanic or some detail was overlooked. I have had 350 plus hours since 2001 running my m3sc on 502 then my 540 as high as 12 psi of boost without EVER melting down ANY motors,Smitty

Re: Centrifical Supercharger Sound !
 

I have to agree with ArcticFreinds..

Re: Centrifical Supercharger Sound !
 

I liked the sound of mine except the random "dinging" at idle. Worked well for me.

Re: Centrifical Supercharger Sound !
 

Burned pistons, valves, etc. are all products of improper tuning. I've been running a Vortech for well over 100 hours and three seasons without breaking anything except drives. You can't really hear the wine with the hatch down at idle. I have a pretty big cam so I do get some surge and loading up at idle, not all the time but usually after idling for long distances.

Re: Centrifical Supercharger Sound !
 

I had some V-4 Vortechs. Very quiet at idle, nothing liike a roots style. No surge runs like stock. Make sure the carb is setup for blow through. Send it to Nickerson. Anybody that blows engines like described above is clearly not setup right. Obvious lean condition. Superchargers are not just bolt on and go. They need a lot fuel to make power and live.

Re: Centrifical Supercharger Sound !
 

Should have fixed the fuel issue after the first melt down....

I run a procharger M1 and yes it does whine at idle a bit more then I would like but im used to it. Also I have a a crane 731 cam and I think its perfect, it will idle at 800 rpms without a problem and sounds real nice too, not too much but definately healthier then stock.

Most people who have had issues with prochargers or any other supercharger for that matter did not have them setup correctly. A stock fuel system just is not good enough to run over 3psi.

Bottom line I LOVE the sound.....

Re: Centrifical Supercharger Sound !
 

heres a idle video after installing the ext box last june but you really can't hear much so I don't think its what your looking for,Smitty

Re: Centrifical Supercharger Sound !
 

Sounds good. :drink: :drink:

Re: Centrifical Supercharger Sound !
 

Could be any or all of the above.

Re: Centrifical Supercharger Sound !
 

Tried supstantial upgrade on fuel system. See photo of the upgrade.

Just sharing my previous experience with Centrifical SC. Was so long ago, seems like a bad dream. Moved on to bigger and better things.

Re: Centrifical Supercharger Sound !
 

Still would likm,e to know about the system you used.....as well as motor type 502 mag....500 efi....etc.... and more details about the fuel system upgrade....injectors and such......can you be more specific? procharger or vortec.....etc......

Details man we want details.....

Re: Centrifical Supercharger Sound !
 

What he said..

Re: Centrifical Supercharger Sound !
 

See post #6, my system was a ProCharger Stage III, M3, with a very large intercooler.

2000 season were HP500 carb motors, with lots of upgrades. First season was original carbs with upgrades.

2001 season were HP500 carb motors, with more upgrades and re-done to 509cid. Second season was Nickerson carbs, custom built for the application.

I do not know if I just had bad luck, or other issues raised by atricfreinds in post # 15. Others have done similar upgrades and love them.

For me personally, as I said in post#9, I would NEVER use them again.

Re: Centrifical Supercharger Sound !
 

Thanks Smitty, The boat sounds awsome to me in the video. :cool: What boat are you running that in & what kind of speed are you seeing. I am definatly going to make try to make shure my carb is right from the get go.

Re: Centrifical Supercharger Sound !
 

I'm running a baja 272. The best it has ran is 92.8 mph gps,5800 rpm's,1.50 drive w/32 pitch 4 blade labbed prop,it will run 89 ish any day of the week w/4 people and 3/4 tk of gas. The video was of boat idling in driveway after installing a stellings box this past summer while checking for leaks,bleeding the steering lines out,etc. I usually run ggb mufflers,in the video they weren't back on yet. The sound from thje cockpit is much different,when idling it is like others described,there is a slight ringing noise from blower rattling the step up gears along with a steady slight whine. At wot throttle is sounds sorta like a turbine,Smitty

Re: Centrifical Supercharger Sound !
 

Sounds like a stock 454 Mag to me... :evilb:

Re: Centrifical Supercharger Sound !
 

What drive are you running ? looks like a bravo ( I would assume an XR.) Any idea what your boat weighs ?
I assumed that I would get some whinning sound which is perfectly fine with me. I was mainly woundering how much cam chop it would cut out , which from the rear it doesn't sound like it cut too much out. Do you know the specs. on the cam you are running ? Have you ever had your engine on a dyno ? Sorry for all of the questions it just that it is winter & cold so it makes for good computor racing !! :rolleyes:

Re: Centrifical Supercharger Sound !
 

Cam is hyd roller around 230/238 at.050 and .610 lift,RMbuilder spec'd it if you want exact numbers on a cam custom built for your motor he is very good. Motor made a little under 950 hp on tyler crocketts dyno at 5700 and a little over 950 ftlbs tq at 4700. Tq band was 800 plus ft lbs from 3500 past 5800. Outdrive is a bravo style with every upgrade part max marine worx sells plus recently a special gear treatment I been experimenting with on the lower gears. I repair my own drives and have a full out max worx drive for a spare too. Most their parts along proper,exacting clearences will help a bravo live for a while in a single v(mine is around 5500-6000 lbs w/fuel and passengers) with some pretty healthy power.The mufflers help my boat idle better and do not slow it down whatsoever,i just had them off in the video because we were in process of putting boat back together and they weren't on at the time,Smitty

Re: Centrifical Supercharger Sound !
 

My M3SC sounds like two wild pigs f*cking!

vortech, resurrecting a 6 year old thread lol

I really like the Procharger F3R reverse rotation, with a custom made intercooler and 600 cubic inches.

Some of these cars make 50psi of boost

HP500, Aluminum Heads, M1 w/ intercooler, 3psi

Man, look at all that room around the engine to work!
