350 MPI needs more performance

Any advice on upgrades on a stock 2000 350 mpi or just build another engine. I would like to be around 400 to 450 hp. and a supercharger would give me that. It seems that there's not alot of supersharged small blocks around. Any leads on upgrades new or used please give me a call. [email protected] Thank you Jeff

Just curious what boat you have this in, and what kind of numbers you are running... RPM's, top speed, etc?

Justin , it's a 22ZX it runs around 56 and turning 5k . It has a bravo 4 blade 22 pitch. The motor runs excellent and burns very little gas , but I need some more speed. Jeff

Keep this post at the top, I know there are some guys on here with the same boat. Maybe do a search for the 22ZX. From what I've read, the 4 blade's are great for accelleration, but not as good for top speed as a 3 blade.

Hey Jeff,

I also have a 22zx. My top speed is 64.3mph on GPS. I use a Bravo 1 4 blade with 24 pitch. I asked a question a while back about a k&n filter but no one seems to know. I have heard it can increase rpms 200-400 adding 1-3 mph, but it is only rumor.

You probably wont gain a whole lot with the K&N unless you have a really small flame arrestor. Take off your current arrestor/filter and go for a quick blast and you might see 200 RPM. I run with a K&N and the Air Xstream filter top, maybe picked up 100 RPM with the top but it may be the cheapest HP gain at only $60.
