Looks even better in the boat! Wish mine was haulin ass. Hopefully soon. I'll let all the yahoos get winterized and get Eddie back out there!

None that I have personal experience with. The shop that did mine did a nice job with the ECU program, but cut corners on everything else. I got tired of taking it back to them because they were way across town and kept my boat forever. I eventually worked out the bugs myself in my garage. None of the problems were caused by the SC kit. They were all due to sloppy workmanship and laziness. They had my boat in their shop for probably 6 months total to do a SC install. It was ridiculous.

I think a good initial setup (ECU, timing, fuel pressure) is key. Mine was good from the start. I get no transom soot, nice color on the spark plugs, and a smooth idle. It behaves just like stock power....until you start laying down the throttle.

What about a ROOTS BLOWER.... can the same performance be achieved and is there a major $$$price difference? I've come across a few USED superchargers... would I be gambling by looking at a used system?

Don't even think about adding a supercharger with out adding an oil temp gauge. It may save your engine. Your oil system should be able to keep your temps down to 240 at full throttle on extended runs . Don't ever let it go over 280. Something is wrong if it runs that hot.

Roots blowers work, but they are not as efficent as a procharger or a screw style like a whipple. ALso used is VERY buyer beware. Some are a deal, others end up costing you way more than RETAIL before you are done. I suggest getting a new one for your specific application no matter which one you choose or where you buy it.. It is the safer way to go.. Jamie

I have a 454 Mag ProCharged M3SC and Modified. This is my second build on the motor 4200 lb 720 hp dynoed in a 280 Velocity I run a solid 85 mph and have almost hit 90mph stock was 70 mph. You do have to be concerned about the drive, it is the week link as I have learned. I currently run a B-Max. The stock motor will be good for a year or so depending how you drive it and the number of hours on it now. If I had to do it again and had the budget I would do the rebuild. upgrade head gaskets (I am now O-Ringed) I blew Kometicts at 250 hours. Good pistons and Iconel valves. You will do it eventually. And dyno it. Find someone who will run it as installed in the boat completely dressed as you would bolt it in yours. I used Tyler Crocket, Thanks Tyler. The computer also needs to be reflashed based on what the dyno tells you. I would install a Fuel pressure gauge and a boost gauge. My $.02

You did mention engine life,don't plan on running a supercharged engine without expecting to cut the rebuild span by at least 1/2 if not to a 1/4 depending on how much boost and how often you are in the boost. A 454/502 mag will normally last 400-600 hrs between rebuilds,ran hard 100-150 hours is about it,ran conservatively (with the ecu tuned perfect) you could see 200-250. My 502 m-3sc procharged 502 was still tight at 100 hours,at 175 it was burning oil and leaking from just about every gasket from blowby, (7-9 psi boost)I rebuild my 540 every 100-125 hours now,12 psi boost at wot,Smitty
