Procharger kit is supposed to be a bolt on addition with no major changes to the engine components. Boost will be mild, and I don't run too hard. The kit does come with fuel regulators, and I can always add on components as needed later.

ProTec Marine in Orange Beach is doing the work. Great people. They work on boats a lot crazier then mine. They are confident in this project.

All the blower guys say that so they can sell blowers.

If they said- yeah to make it live you'll need to tear it down and rebuild the bottom end and work the vale seats, cooling etc. they would be sell far fewer blowers.

Never had a "bolt on" blower engine last more than a season.

One lasted 4 hours when it leaned out.

I dont wish you ill in the slightest- just passing on my own experience.

Prochargers are probably easier on your rig than a screw or roots blower, but you have to mod the fuel curve at a very minimum.

Sounds like a great project in any case. Curious to see how it all goes down and how long it lasts.

sounds like your 292 is finally gonna get some power it was meant for. Good luck and let us know when you have pics/results

I agree with Uncle Daves take, NA. I went down the road of supercharged and it was fun, but burned me in the end. Never again...NA all the way, but I wish others the best of luck cause there is nothing like the torque from a blower motor...and the whine is pretty cool too!
Personally, I think the new Ilmore small block is the ticket for these 292's!

You already have scorpions you need to get that thing some whipples and CMI's Kinda agree though I would rather find a 292 ready for power soon and go with one of the Ilmor V-8 with an outdrive setup...could be any of the 400+ motors and I would be happy I think

Agreed the Ilmor "small block" it is a fantastic piece of work.

I also happen to be a fan as I own another boat with an Ilmor 710 in it - and its a wicked piece.

But I think the bucket if duckets is a bit unrealistic to spend given the scope of whats on the table right now.

But he does have money to spend and its up to us to help him do it right.

To make the procharger engine live he really cant make more than 100 ponies more (even thats pushing it) or it'll detonate to death. 1 bad batch of gas at the end of the lake and a hard stik and hes done. Plus the stock injectors will be at the high end of their duty cycle by the time they are tuned for the additional ponies (if they are even good enough)

This wil cause oil heating issues, and likely steering issues (do you have external steering?)

I would lean toward a top end kit or the 400HP "reman" build of the same engine he could just drop in..

Said top end kit would include....

A real set of aluminum heads (Brodix/AFR/Dart) and carbs, manifolds, cams
A real exhaust system set
A set of oil coolers

I say carbs because there is work to do to the injection systems to keep everything happy with another 100 ponies & because hes already resigned himself to bigger injectors and maybe even a bigger fuel pump(s) and possibly a recirculatiing loop if he doesn't have one today.

This will make about 75-100HP more that what he has now and be roughly equivalent to what he'll get by bolting prochargers on a stock engine.

Hed get a bunch of seasons out of this, pick up a grip of speed, and have really good parts for when its time to go into the bottom end and do forged internals for a real blower engine.

I also went down the Procharger road before. You need to change the injectors, upgrade the fuel system, add oil coolers, and reprogram the ECM or you will have problems. That bolt on and go stuff is BS. I would also upgrade the head gaskets. Prochargers do work and stay together if done right. Jeff Wurl

Ok, some of you guys have justified my hesitation on posting about my build. I appreciate the suggestions and wisdom, but at the same time some of us government employees don't have 30 grand to drop on an engine build all at once.

I got these kits at a great price from a close friend who ran them on his 292 for a few years problem free before he sold his ride last year. I also have faith that my shop would not send me down a road that would result in my motors getting trashed. I did present all of those questions prior to obtaining the parts and doing the install (head gaskets, fuel system, exhaust, etc).

I created this thread to share my experience and results to those who have been considering a ProCharger system. I have done my research and read all the pros and cons. At this point I am not interested in comments regarding what I should do to make it "right" or anyone's bad experience with a supercharged motor. Everyone has their own way to skin a cat.

I look forward to posting some numbers for those who are genuinely interested in a possible upgrade to the already awesome 292 or Mercury small block!

Don't let others get you too down...your boat, your money! I will not lay off for not having any pics though...and you BETTER post some #'s when you get them

I love my prochargers, have 11 seasons trouble FREE! You sound like you have your head on stright. You boat will be fine.

Looking forward to hearing the results. My close friend has a 07 292 that is in need of chargers! Hopefully this thread will talk him into it.

Thanks for sharing.
