Pro and cons of a PROCHARGER
 

Anyone had great results of applying a procharger? I've heard of some working and most not worth the extra $$$.

Re: Pro and cons of a PROCHARGER
 

when i originally installed a procharger i took my boat ( a502 mag,272 baja)from being a 62 mph boat to a 78 mph boat. There are not many mods that will give you 16 real mph other than more cubic inches,Smitty

I got 2 x M3s and intercoolers for sale.

Re: Pro and cons of a PROCHARGER
 

If you are interested, ProCharger is running a sale until October 30. Call 614-545-2628, most often supercharger is installed for less than the MSRP.

They sound like a box of marbles rolling around under the hood :D:D

The ones that I have seen are amazing the performance that you can ESPECIALLY when combined with the super chiller.

Set up is key!!!!! If the fuel delivery and carb is not set up right you will have problems.

Re: Pro and cons of a PROCHARGER
 

I feel the procharger or vortech is easier on the bravo drive then the whipple. Whipple has full boost when throttle is open at any rpm. Procharger builds boost as RPM goes up thus does not have the torque that the whipple has. Procharger has good products but there tech support has sucked in the past. Better to get tech support from here on OSO. When I was looking I went with the procharger because I was afraid of having to go efi with the package I was looking for to get it to fit under the engine cover. The Procharger M4 package had carbs and was priced way cheaper. Tomcat has done some tests with his suppercooler & gotten some impressive HP numbers

Re: Pro and cons of a PROCHARGER
 

Procharger, I have not used procharger however, I have used Plenty of Vortech chargers. Let me clear something up for you. A supercharger does not no anything other than to spin and move air. Some create more psi such as a centrifical (Vortech) charger. Some just move air from the top to the bottom.(roots) You here a lot of bad things about certian chargers because some guys installing do not no more about a supercharger and the way they should be set up then what the directions say. Some manufactureres directions are not the best way to go about supercharging. Such as just increasing fuel psi vs remapping the computer etc. Yes a centrifical will create less torque down low, because they are not spooled up like a turbo yet. If going with a procharger I would suggest consulting a professional about the proper way to set it up so you have no major problems.

Re: Pro and cons of a PROCHARGER
 

I am happy with my procharger carb version . I do have a nickerson carb though. Those guys are right setup is important, then you shouldnt need to touch it . Greg

Re: Pro and cons of a PROCHARGER
 

I have been wondering the same things.

My questions are:
prop changes, I have 23 mirage plus with Houston prop mods
71.3 is the best speed ever at 5000 rpm. What ballpark prop will I need?

Twin 350's MPI motors. 1.5 ratio bravos, stainless marine headers.

instructions say no computer reprogram required, any comments?
For 5psi the kit comes with the required fuel components, are they sufficient? I am assuming it is just a regulator.

I am also planning on boost gauges and fuel pressure gauges for both motors, is this all I need to keep an eye on?

drivemhard, contact me and I will give you a name and number of a guy that gives the best price, I have been pricing for a while.

Re: Pro and cons of a PROCHARGER
 

I would get Boost/vac guages fuel press is good. Are you doing the install? It would to check the EGT before the install and after even just on 1 cylinder. you should go 80 plus easily on 5 psi. If you dont raise the rev limiter then prob. 27s. Like anything thats close to mech limit I wouldnt hold it wide open and just drive even though you and the hull may be able to. Use the power to race otherwise just take advantage of the higher cruise speed (3-4K) I love mine, Greg

Re: Pro and cons of a PROCHARGER
 

Is there an easy to check the EGT? What do you mean by fuel pressure is good? Should I go ahead and buy the fuel system upgrade listed by ATi for 7 PSI even though I don't plan on running 7psi? Any idea what the upgrade consists of? It is not that exspensive. I have oil temp gauges, will they be good indications on how hard I can run it? I don't want to raise the rev limiter, I figure it is safer the way it is. I want dependable power, we are weekend family boaters. I figured 27's I will have to see if I can borrow a set from someone to test with.

Thanks for the help.

Re: Pro and cons of a PROCHARGER
 

You can drill some exhaust manifolds at the head flange and install a 1/8 inch thread pyro. I would do the cylinder that typically runs hot. (I dont know which that is on a small block) 7 psi of fuel pressure is an conservative figure 5psi would probably actually work. 7psi will make the motor a little richer but safer. When I said good, I meant its good to have that fuel pressure guage to keep an eye on. Your oil temp guage is a good indicator of how hot it is getting inside. Running any motor at wide open throttle at 5000 rpm isnt all that good for longevity.If you cant win the race after about 30 seconds why stay at full throttle? Hopefully the boat will be close to the ragged edge and real light to the touch (to get that adrenaline rush). You'll like it! Keep us posted in the outcome we want to hear it. Greg

Re: Pro and cons of a PROCHARGER
 

I am having an extra set of engines built. The builder has 4-6 engines on the floor finished ready to go with pro-chargers. I am hoping he will have those in a boat by the time my lowers are done. Still time to make that decision.

With his set up you shed about 300 lbs of hardware with prochargers per doggy.

Re: Pro and cons of a PROCHARGER
 

the 7 and 5 was blower pressure, not fuel pressure. I would assume my MPI motors have more fuel pressure then that.

I agree on running it wide open for long periods of time.

Re: Pro and cons of a PROCHARGER
 

They do have higher pressure and I was reffering to fuel pressure increase to compensate for the boost in the manifold that the fuel pump must overcome. Sorry. If you can afford it go for the better fuel system. Just in case, you never know when you to want to go little faster. How much do they charge for thatfuel sys. and what do you get?? Just wondering. I have a carb now and want to go efi. Greg

Re: Pro and cons of a PROCHARGER
 

$129 as an upgrade. Look on Ebay, there are two complete injection setups for a BB with a procharger for around a $1000.

Re: Pro and cons of a PROCHARGER
 

Prochargers with Nickerson reworked carb is the only way to go!!. Nickerson did a lot of developement work with Procharger. I always had excessive richness on mine until Nickerson reworked it. I only had to raise the idle about 100 rpm on carb return. Metering was perfect. I loved it!!

My 93 Formula 252 went from 52mph to 76 mph ( a little more was done than the 'charger). No problems at all. Great setup. Also what TurboJack said. Trust oso experiencenot Procharger techs... :drink:

Re: Pro and cons of a PROCHARGER
 

HPJunkie,
I think my brother Jake lives down the street from you! :eureka:

Re: Pro and cons of a PROCHARGER
 

TheDykstras, yes he does. Hes told me about your boat.Do you need one of those prochargers too? I think so...Ha ha. Anyway hows your boat running? Nice to talk to you maybe well meet up and do the liver punishment thing sometime? Greg

Re: Pro and cons of a PROCHARGER
 

If the engine is carbureted then consider using this setup. We sell the box separately for Procharger upgrade but sell the complete kit with Vortech blowers. The picture shows a Procharger upgrade from the same angle as HPJunkie.

Hey Greg, how's it going? Still interested in going EFI? Wait till you see my new design!

Re: Pro and cons of a PROCHARGER
 

Tomcat, I am good and you? Yes I am and yes I am! Your new design? Bigger ,more effiecent, different look, ....More power? Im thinking about Cobra Martys EFI for sale. You say 1000 cfm will support how much HP at say 14 psi boost or wont that work? Greg

Re: Pro and cons of a PROCHARGER
 

Marty's intake will work with the standard supercooler. 1000 CFM is good for about 625 HP. Multiply by the density ratio to get the supercharged HP that is possible with a throttle body rated at atmospheric pressure. 14 psi with a good intercooler should give you about 1.8 X denser air; 625 X 1.8 = 1125 HP. A Procharger M-4 of Vortech V-4 with X or XX trim will deliver the required flow.

Getting this much boost becomes an issue with upper pulley size and belt slip. Don't forget that the blower has to develop an extra 2-3 psi to overcome resistance in the intercooler pathway, more if you're not using a supercooler. This starts to consume a lot of power and puts strain on the whole blower drive.

Re: Pro and cons of a PROCHARGER
 

14 lbs with a supercooler @ 5900 rpms should be no problem with the procharger M4 in a 540. 8.5" lower pulley & 5.5" upper I think will give you aprox. 13, go to 5.25" pulley & boost will be???

Re: Pro and cons of a PROCHARGER
 

Hey Jack:

You're right, with a bigger crank pulley you can get the right pulley ratio with a reasonably big upper pulley so you have enough belt wrap not to slip. You can always go to a wider belt too. But the HP curve for a centrifugal device is fairly steep. that's why you see chain driven Prochargers on the drag cars. Pulley changes are cheap, but I prefer to take the other road, which is reduce overall system resistance, This can be done with better heads, better intercooler plumbing, bigger throttle body, you know the drilll...

P.S. I've got a box here with your name on it (magic marker on the special Dominator bottom plate!) If you're still interested let me know.

7 and 8

Re: Pro and cons of a PROCHARGER
 

How much are these systems usually? I was just on the Procharger website and there is no pricing that I could find. I have a 502 mpi in a 28' stryker. I am getting low 60's for top end now and would like to at least get into the 70's while still maintaining reliability. will my Bravo 1 hold up to this type of increase?

Re: Pro and cons of a PROCHARGER
 

a little less then 5 k LIST, there are some good deals on them right now.

Re: Pro and cons of a PROCHARGER
 

About what I thought....from what I'm reading it looks like installation is key. I'll have to check on the installers around my area so I get it done right. It seems like the best overall package.

Re: Pro and cons of a PROCHARGER
 

I didn't know super chiller make a intercooler for the ProCharger. I have great results with the intercooler provided.
One only real problem I had and heard other people voice was tech support. Lake Shores Marina has a ProCharged Scarab that was the fastest V at the Shootout. Jason is a member here and goes by bilgerat.
