If so, what did it take to get the boat there? How does this boat handle at these speeds? What drives were you using? Thank you.

I'm shooting for the same thing. I will try it with hp500s/prochargers at around 750-800hp. Just got the intercoolers today. Mav35 is running around 110mph in his 1997. Mine is a 1995.

I think 10X, Frank, is running 850 hp a side ? and runs 110 or 116 mph something crazy...

Yes, I have a 2000 35' single step that runs 100+. 588cu in., 845hp, stelling boxes, XR drives w/ 1in. shorter lower halves. Right now running bravo props 15 1/4 x 32, and it is definitley under propped. No problems handling, but i've been driving fountains over 100 for 12yrs.

Looks like I won't have quite enough horses with my 540's. Those are some big engines turning an insane amount of hp!

Did you see a good gain from the extension boxes and 1" lowers?

Good luck, also, to the person using the prochargers - how much hp do you expect with that set-up?

Not at first, then took boxes off and raised all the way up. Then worried about drive shaft angle so I raised motors up an inch. Then had to change exhaust tips on headers, ouch $1800, and noticed some top end gain. Then put 1in. lowers and noticed maybe 4-5mph total. The big difference was when I went from a dart 360 head to a dart big chief head. It gained over 100hp from the head switch, but took alot of work to get the heads to fit in the boat b/c the extra width of the heads.

Frank's boat is a 10 Meter. No steps back then. Just lots of HP.

Knucklehead - I was considering going with the lowers this year but want to see what my existing set up will do first. My x-dim is at 17 1/4 according to Fountain. Do you think I'm leaving some mph on the table because of drive height?

Explain more on the exhaust tips. I had my tails changed so that water is introduced as far back as possible, so I had to have special tailpipes made by CMI - $2,100. Now the pipes are through my transom by 7 inches.

My X is 16 3/8 according to the performance report.

rebel heart-Not sure on your x-dim. if you dont have boxes I would try the 2in. shorter lower halve. If there to high you can space them down. I dont think you would half to. On the exhaust tips I rase my motors up 1in. the exhaust tips just would not go on I tried everthing.
