Prochargers on Jets??

[Ken F]

Anyone in here running a procharger on a jetboat?
Pros & cons????

I will be running a Vortech V4J centrifical supercharger on my 509.Building it for my Eliminator Scorpion.The Vortech is similar to a Procharger.I seen a jet for sale on ebay about 2 months ago with a Vortech supercharger.I think why you dont see too many of these type of superchargers on jets is there is less of a WOW factor than running the roots type blower.Hopefully by the end of june I will have answers to the pros or cons of running this setup.I have a Procharger P600B intercooled system on my 91 Mustang and it works great.

[Ken F]

Yes, I've been talking to some car guys, and they say that most people are running them at the drags now. Just got me to thinking......and that usually gets me in trouble!!!
Hope it works out well for you. I'm going to do some looking into it.
Thanks for the heads up on the Vortec stuff!

Ken, Give these guys a call. http://www.stevemorrisracingengines.com/engine-pictures.html

Contact Bowtie Rick here on the boards. If I remember correctly he had a procharger/paxton/vortech on his 21' open bow.

Just did dyno testing last week (Monday, April 24th) at Vrbancic Bros with my new 540 motor and Pro Charger F2. The engine is 8 to 1 static compression and did a little over 500 hp by itself. With the F2 and C16 race gas the numbers stepped up to 913 hp and 908 ft-lbs torque. Found out two things though. My current valve springs are too weak and the cam needs to be a bit larger and about 20 degrees longer in the duration department. I should be be able to run the numbers to darn near 950 - 975 with a little more tweaking on what my current parts are. Better heads and a cam would make 1000 hp easy. :cool:

what boost level??

[DEL51]

Ken. I think you are smart for checking out these systems.If you intercool them it gets more expensive and if you intend on running the carb the cost is less. Packaging should be no problem in your boat.If you do the carb system first, you can always upgrade to an efi system down the road.

[Ken F]

Thanks for the replys guys! Havn't really had much time the last few days to do much researching tho...
Del, yes that it what I was leaning toward-the carburated deal for now.
Is this what you are running on your boat?
Ken

[DEL51]

Ken,I have roots blower with 2 1150 doms. I think your potential setup will be more effiecient. I am running low compression and steel heads.

[BOOGEYMAN]

Go carburated!!! Much cheaper and you can tune it with a screwdriver on the lake! If you want the best carb for a blow through set up go to www.csucarbs.com and check them out. Kevin is an outstanding guy and will answer all your questions. Every carb they sell is almost perfect on the tune for your set up right out of the box.
You can also call Kevin anytime on his cell @ 909-851-6955

It would be interesting to hear more about your engine combination and set up.

I have seen some real impressive numbers from procharger blow through carb setups.
I don't think it is going to be that easy to tune on the lake though because you have to take that big cover off to even see the carb.
I seen one on a 24' Baja at a local lake and the performance was impressive but it spewed out black clouds. I think the WOT tune was good but the idle and part throttle tune was way rich.
Lack of tunability is always going to be a problem with a carb.

[BOOGEYMAN]

Kevin's carbs are top notch.....guys are making 1200rwhp with the 750 on a 302ci engine and driving the shit out of them. Driveability used to be a big problem with a blow through set up but with all the brpv's (boost referenced power valves) and what not they pretty much drive like a stocker untill you mash it.

what boost level??
The F2 was registering 24.5 lbs at 6000 rpm. Not the ideal thing to actually run on the water but we we wanted to see what the motor could take to find the weakness. Like I said the valve springs and cam size need attention.

What's A Whole Carb Set-up Procharger Cost? I Can't Fit A 8-71 Or Etc. Due To Lack Of Space In Frt. Of Crank.

Ok, got a whole bunch of info from Procharger in the mail today......
Damn they are proud of that stuff!!!

Ken f,
I can get you a better deal than pro charger will sel you one. Pm me with your info and I will see what I can do.

What kind of numbers do your heads flow??? That thing should be making an easy 1250 or so @ 25lbs and c 16. Wha does your timing look like?

[HTRDLNCN]

Centrifugal chargers are more efficient but have a completly different power curved than a roots.
While a roots makes almost instant boost off idle and fallsoff on the high rpm side Centrifugals (vortech,Paxton,Procharger) make linear boost that basically doubles every 1000rpm. Basically if you set it up to make 10lbs boost at 5000rpm it will only make 5lbs at 4000 and 2.5lbs at 3000 and 1.25 at 2000rpm.
In other words you need to spin it to make power.
Just something to keep in mind. In a car I love them because the linear ramp up makes it easier to hook up and the top end charge is unreal.
They are also more forgiving on driveline parts since you do not get that huge torque punch at low rpm.

I'll have to go back and check the info on the timing numbers. My thoughts were in the 1100 hp range myself but obviously my motor came in a bit short of that. The Holley heads aren't huge and that much boost is too much for them to move properly. The boys at Vrbancic have a 468 ci Chevy motor with the same heads, a bigger cam, smaller intake, and smaller Pro Charger and they have seen 1057 hp at 15 psi with alcohol. For you Ford guys they also have a 331 small block with the same blower as mine and it did 1200 hp. I just need to iron out the wrinkles. With a 540 and almost 25 psi I should be rolling the dyno to the tune of 1100 - 1200 hp easy. :mad:

Yes 1200 should be very easy with that 540 and 25 lbs!!! A buddy just made 1220 with a 406 small block and 25lbs with an f-2 and c-16(were nice heads). That engine will be an absolute monster when you get it dialed in!!! Call steve at www.stevemorrisracingengines.com and he can hook you up with the exact cam you need!!! he has a 572 that makes 1600 on 114 oct. or 1600 on 92 with an air to water with an f2 and 25lbs at 6100rpm!
