Hammer needs to do 80+
 

Hi, I have a 97 Baja Hammer w/ 454 mag mpi motor. Looking for options on getting this thing to 80+ on the water so far my best has been 75 on the speedo. Not wanting to go crazy and lose reliability or to much fuel efficiency. Didn't know if anyone had any input. I am looking for solid 80+ not just making the stars align and hitting it every now and then.

get the checkbook out and also get a gps speedo instead of the factory probably no where near 75 mph other than on the dream meter definately get full hydraulic steering for those speeds

Better hope you wanna do 80 on smooth water. I think the hammer has a 21 Degree deadrise? It will not be stable.

You need to get the steering taken care of first, if you plan to go that fast.

^^ This. If it's a stock 454, you aren't anywhere near 75. Get a GPS unit or if you have a smart phone download a GPS app.

Mine does great in a chop, just not rollers. That being said, I wouldn't want to be making a WOT run in even a small chop with a stock Hammer, much less one capable of 80+. :P

You're going to need external steering, a belt
driven air cleaner or something in the 500+ hp range to
get there.

Then, the right water conditions.

ive got a 525sc blower that will bolt right onto that 454. makes 5lb of boost. that will get that hammer moving for sure. pm me if interested

Supercharger will definitely get you close, like stated before external steering and maybe longer trim tabs

Thanks for the advice where would I look to get a ungraded steering system. I did a quick search and didnt find anything, what does it add to what I currently have?

It eliminates the factory system that is not reccomended for speeds much over 70mph(your probably actually running high 60s now) with an external system. Depending on the system your looking at $2000-4000, figure another $2000-$4000 for a supercharger if your engine is healthy , new prop matched to the new power , another $500 , little things like bigger oil cooler for engine , wideband air/fuel gauge, boost gauge, reprogram the factory efi for the blower , bigger injectors and you should be set .. All in all probably 10 grand should get you there correctly..

ive got bigger tabs for the boat too. buy a used steering kit out of the swap shop for 1/2 of what they are new. hundreds of props for sale cheap too. 5300 rpm with a 28 pitch prop will get you 80 (prop slip @ 12%)
