so i thought about gettin blowers

procharger, whipple,vortech

whats the difference

performance
price
reliability
life of the motor
resale
effect on insurance

did i forget anything?


oh yeah... who has done it and are u glad?
any headaches?

BLUE MOON the 36 APACHE has them and he boats about 250-300 hours a year. They have been on for a couple of years. Ben at Percision Power Offshore here in Grand Haven can do it for you. They are a real nice setup. Call Ben 1-616-844-1000.

Re: supercharging a 500efi
 

Ted,, I know the Blue Moon boat and its setup,,, Steve is right ,, It is fast and very reliable,,, Ben did a good job on it and they run it hard and fast !! I think you would like it on your Playmate eeerrrrr Playboy!! :D :D :evilb:

My old single was Whipplecharged and my current twin setup is Whipplecharged. Would not have it any other way. What you need to do is go for a ride in a boat with blowers. Once you go for a ride you will want them on yours. Just make sure you set it up right from the beginning and you will have no issues.

Re: supercharging a 500efi
 

The Rtech system for that engine produces a reliable 800 HP with reprogrammed ECM and upgraded fuel system. That's about the limit for the stock engine. You need 12" clearance above the stock intake.

Almost everybody that supercharges ends up wanting more. Our blower and intercooler are good to 1000 HP but the engine needs much better parts to take the extra power.

Good Luck!

Tom,
What is the price of the R-Tech system?

Re: supercharging a 500efi
 

performance: better
price: a lot
reliability: upgrade is good....drives can get hurt
life of the motor: we'll see
resale: who cares
effect on insurance: went up some

I'm glad I upgraded with that. It made it a new boat for me and I liked doing the project. Remember, it's not just the motor, but you have to have additional gauges too. Fuel pumps, sea strainers....blah blah blah.

In business, I design various things, so I designed the new dash plates and asked our sheet metal place to make new ones and repaint/silkscreen them all. Looks nice (to me). I still don't know the performance increase since I didn't replace the speedo (80MPH) and it pegs that.

It had XZ drives, which are good drives, just not strong enough. Now I have one XZ and one XR. The XR uses more power to turn and therefore has less RPM.....just waiting for the XZ to blow. I moved from Bravo1 28 labbed to 32 stock....but now I'm trying 30 stock. Seems about right.

Re: supercharging a 500efi
 

what kind of drives is blue moon running?

and shame on you to mention a boat by name and not post any pics!!!!

you should know the rules by now OLD MAN :eek:

Re: supercharging a 500efi
 

The dash project.

Re: supercharging a 500efi
 

More.....

Re: supercharging a 500efi
 

my engine guy is looking into whipple and procharger

nort how many mph did you pick up?

Re: supercharging a 500efi
 

I picked up 16 mph on my single and 20 mph on the twins setup.

Re: supercharging a 500efi
 

Still not sure.....

Re: supercharging a 500efi
 

fuk! is that on the 36 outlaw :eek:

Re: supercharging a 500efi
 

i figure id run in the mid to high 90s
which would be a 15 mph

Re: supercharging a 500efi
 

Dreamer, if the playboy your talking about is the white one with the gray interior that has the pro chargers, i was told it runs 103mph

Re: supercharging a 500efi
 

Dreamer doesn't yours run in the low 80's now?

Re: supercharging a 500efi
 

Nort nice looking install.

I would recommend the Whipples . He will have them ready soon. I would say it would make around 750 on a stock500efi.. They have a much better and cleaner package. The pro charger works also but the innercooler you have to mount some were :eek: they recommend the stringers :( The Whipple has a better innercooler at 9+ pds boost the air inlet temp was only 10 degrees higher in the intake over abinant.this was on a steady state pull!!!

Now the Whipple comes on hard early in the RPM. were the Procharge comes in later , The Procharger would be easer on drive ,if ya stab it say from idle or like mine has about 5-6 psi at 3000rpm.800plus TQ :eek: I usually wait to after peek TQ at about 4500 before I stab it.

Now the Pro charger is defiantly cheaper.

Ill post some picks when I get to the house

Re: supercharging a 500efi
 

I have heard that the vortechs power curve is better suited to preserving drives.

Re: supercharging a 500efi
 

Thats redneck boating if I ever heard :D :D :D

Re: supercharging a 500efi
 

Semper Fi: Give little Bill a call at Victory Marine. He advertises on OSO and he is an Rtech dealer.

Rob: You know I can't let you get away with any loose talk about intercoolers. :evilb:

There are two things cooling the air in supercharged engines; the intercooler and fuel evaporation. Where you are measuring manifold air temperature on your Whipple, both things have occurred so it's hard to comment on the cooling efficiency of the intercooler alone.

I have never tested the Procharger 504 intercooler but we have monitored temps anywhere from 78F (@6psi) to 90F (@8psi) using 70F lake water during WOT tests of our systems in the boat. The only thing that makes this possible is having a big intercooler.

Nort: That is a sweet looking dash...having any trouble reading them all at speed? :D I'm always asking my customers, "What was the boost and RPM?" They never know... :rolleyes:

Re: supercharging a 500efi
 

Thanks TomCat..........that's why the boost gauges are right next to the tach's. Easy as pie to see together. :D :D :D :D

Re: supercharging a 500efi
 

Yeah yeah yeah...........not me baby! :D :D :D :D

Re: supercharging a 500efi
 

Nort,

I am selling a pair of 4 blades 30" labbed. I am underproped now that I re-built, changed pulleys, added super-chillers and blahh blahh blahhh... Anything you would want?

Re: supercharging a 500efi
 

True fuel evaporation helps too The sen is in the back lower part of intake :D I wish it had direct port injection that would be nice :drink: vroom vroom

Rob :D

Re: supercharging a 500efi
 

any other blower brands?
and what are the prices per side? for each brand














or someone buy my boat so i can get something BIG w/ #6s
