Hopefully you will see high 70's to 80 MPH, but everything will have to be right to get that heavy of boat to those kinds of speeds. As for Nickerson Carbs they have worked very well on my NA motors and friends' blower motors. Don't mean to make you puke Bobby.
Hey Bobby,
If you want a shot with one of your carbs I am willing to give it a try, but only with a radar speed increase guarantee while maintaining the durability and clean idle of the Nickerson. My boat does 98 MPH and if you can find me 1 or 2 MPH without leaning it out I am all for it. With the 13.2:1 compression ratio I run if it gets lean detonation sets in pretty quickly. Let me know.
Oh ya no black transoms allowed either.

Hey ,as you will note all my references have been towards blown motors ,right .
Anyone can come to you with a carb and tune it at the lake for you and get more speed ,THATS NOT A PROBLEM ,I don't care if its me or who if they are true tuners ,,,so you offer is good but would not be fair to you .
The issue with nickerson stays ,,he needs to idex the blower motor carbs which is what I'm saying and have been saying .
If he made you happy thats great ,thats what counts ,I don;t think for 1 min. I'm the carb king I have a lot of friends who do better and as well (blown1500 is one ) but they all to my knowlge
index power valves ,
This is stupid for me to argue about with you as I don't think you even begin to grasp what I'm saying ,I'm trying to help people do better with their blower mt.and thats it , I still agree with cessna ,ect have a good one

Bobby,
I do understand boost-indexing, and have seen with my own eyes some Nickerson carbs and I promise you they had been boost-indexed (external line and all).
Maybe he doesn't do them all that way, but these carbs were Holley box-stockers that came back boost-indexed, and had the powervalve feed holes enlarged, along with some other mods. The owner had no idea what Nickerson had been "instructed" to do with the carbs (his engine builder had sent the carbs to Nickerson with instructions) but the carbs were shipped directly from Nickerson to the guy who showed them to me before he bolted them up. He only showed them to me because he thought they looked cool and I was somebody he thought would appreciate them (poor guy - they just looked like carbs to me). He did let me take them apart and look at them.
He also bolted them up and they run well. 250 blower.

Amazing how a simple question about speed can turn into whats the best way to tune a carb within only 6 replies. If I know you Tim, you have investigated this topic throughly before you sent the carb out.
My guess is that you will hit 83mph using a 28" prop.
Good luck.
Whats the winner get??????

My blower motor carb was also done by Nickerson and i have no problems.....But i also had the motor dynoed there so i may had a far better advantage than most. I don't know enough about indexing to know what he did or did not do, but i have no problems whatsoever.

Hi-perf 2000 your right the dyno would have shown the to rich condition and I bet yours is right
US 1 ,,, cessna and the others of us where only doing what this board is for that is trying to help others like Tim and Hi-perf and Biggus,who don't know what indexing is !!
And giving biggus a chance to post picture his motors .
I don't think cessna brought this up execpt to help and voice his views like myself ,this old lady bickering is what makes guys who know stop trying to help others learn,,they get tired of the wa wa waa ,,,6 post waaaa
Have a good day us1

BadDog,
Just my opinion here:
I've driven that same boat with a 502 (a little under 500hp) at over 70mph. I personally did not feel the boat could be driven at higher speeds safely.
I would sincerely hope you have external hydraulic steering on it. With the wear and weakness of bravo gimbals, you'll definitely need it for those speeds.
If ANYONE needs a reminder of what can happen when adding a lot of hp to a boat, look up posts from "kook". Sad story.
I'm not trying to preach, just my opinion.
