Prochargers on a 312 fastech
 

Any one have prochargers on their bird.. I have twin 454 mag mpi's in my 312 and seriously thinking adding Prochargers. I run 73 max with 2 or 5 people no matter what I do with 30p labbed 4-blade Bravo-1's 1.65 Bravo drives..
Want to go with the M-1sc's (5psi) quite a bit of work to do properly from what I am finding out...
Was wondering if worth the effort and $$. Has anyone tried?:eek:

thats a sharp 312

353 ....

yes its worth it,,cheepest way to pick up 15-20 mph if tuned rite..do you have hyd steering? also you will probably have to change your gear ratios or turn up the rev limiters...

Mikey ......wasup? close the dam back door ...you guys bout to freeze us southern boys out ....!


:eek:

By the Way Sold the 311 ...now resides in South Carolina .....super nice guy with big plans to take it to the next level ......m

Back door has been closed:lolhit: I think its out friends in canada that left them wide open,,im done with the cold stuff..hopefully you keep the 353 for a while,that is a nice fresh water boat you have,,and alot of nice parts that are on it when you got it..

Be careful coming out of the hole with the extra HP, don't know what kind of lowers you have.

I wouldn't do it. I had a 312 for a few years......it gives weird handling when getting towards 80 and above. I just waited and got a bigger boat.

eh......just threw it on there .... everything is for sale ...turn key boat ....kinda bored ....I'm sure we'll break something this summer though .......M

Imco's ....

Silent, i disagree with Phontom. look at my sig my 97 312 runs great all the way to mid to upper 90's gets a little loose over 100 (runs 102 gps light load) great boat responds well to the imco -2 shorties. Get the right person to tune the motors. also my boat had 1:65 gears from the factory ended up with 1:36 turning 32 pitch bravos. Have fun good luck

IT's killining me to either do or not.. been up for weeks in the am..is that sick or what? I found an installer that does it right but its about 13 grand + pro chargers.. heads worked, new fuel systems, Mefi 4b's and harness, re work of injectors etc.etc. but I guess theres a wrong way and a way to make it live.. at my current 73mph my boat is begging for more.. I feel it wanting to go but it can't. I do have Hyd steering and K-planes. Bravo-1 drives. I'm running 30p labbed Bravo-1 props.. thought is I will need to jump to at least 34's or more.. have to test I guess.. My current hole shot is great..
I guess I need to loose some more sleep and think about it..:eek:

If you have any questions, you can call George at Marine Performance Products. He is a distributor and installer for ProCharger, with alot of experience. Phone # 630-240-5401.

What is on the motors now for EFI?

It's the 454 mag mpi's
