procharger
 

Do you need 2 fuel pumps when you add a procharger?

No, but you should have a better than stock fuel system & you should NOT have the pro charger vacuum-referenced fuel pressure booster control for the fuel pump unless you would like to make your pistons into melted aluminum scrap.
You need a large fuel pump, ie: Aeromotive 1000 or equivelant and a vacuum referenced fuel pressure regulator.
Procharger supplies a goofy regulator that increases fuel pressure via the fuel pump based on vacuum and voltage to the fuel pump. This is a proven-to-fail system! The correct way is what I have listed with equivelant parts (SK or Aeromotive)

fuel pump
 

I have the factory on the engine i think, and the owner put a holly fuel pump on it also, not sure on the set up, but my mechanic is going to contact procharger and check into it

i am just double checking the work the original owner did and make sure it is correct. so i don't have any surprises, that is alll, i am not a motor guy, just a guy with a little bit of brains to makes sure things are done right

Your mechanic would have better luck contacting a vo-tech school for information rather than procharger. They don't even know their project.

You should not listen to procharger unless you want to build a new motor after you melt it down. Procharger done right will last many many years. Done wrong and well? Your mechanic may say you should listen to procharger because he then will be able to build you a new motor shortly.

Do as Jason says. It will be way cheaper to do it right now instead of later.

Back around the late 70's I called Gale Banks about installing their turbocharger system. They told me that the only people that bad mouth turbos were ones that did not set them up correctly. They then gave me a run down on all the things to do correctly. Main one was fuel system done right.

We need some more information.
Size of motor
compression ratio
type of heads, steel or aluminum.
Size of procharger M1-M5
How much boost are you running
carb or efi,
size of intercooler.

Has the anti syphon valve been removed?

Just notice your post is in the Baja section. If question is not boat related (such as this one) you should post your questions in the technical sectoins. You will get a lot more responses. If Jason would have not seen your post and given you the right informaton you may have been building you a new motor and wondering why it melted down.

The only reason I found this thread was because I had done a new post search.

Call this guy Jason at Kunkels Marine I have had 3 boats with Prochargers and he has done hall of them for me with no problems 419 529 4446.

info
 

2009 502 mag
compression ratio not sure
heads don't know
m1 procharger
i think 5 or 6 pounds of boost
carburated
size of intercooler not sure
anti syphon hose no idea

i have the boat at the marina now having full hydraulic steering installed. i am sending my mechanice the info you guys gave me. The guy i bought the boat from only knew how to put gas in it. The original owner did all the work. I am trying to get educated as quick as possible so i don't damage the engine.

How is this different from the new owner?? :stooges: lol
