looking at my most recent dyno sheet, compared to the rpm i'm turning the impeller, the chart isn't remotely close to accurate.

you're doing well with it, and that's great to see. but your engine would have to be pretty fracked up to gain another 50hp just in tuning. the gains are going to happen working the setup. i'm not suggesting you'll ever pick up 10 mph or over a half second of et. but the setup is where the improvements will come from. keep workin it - it's never perfect...

no dyno my hp # is purely based off a similar motor that made more then 700 on the dyno and a few educated guesses from people who helped build and contributed to my build... as far as setup goes I'm not expecting drastic changes. I am however expecting a bit more out of the impeller cut and getting this motor on the pipe. at 6000 its singing but she aint screaming.

I've had mixed results with this boat and hardwear and i can tell you this particular boat reacts well to even the smallest changes. For example took the ride plate down a degree and it ran 5 mph slower then my initial setup. went up with the air plates a deg and porpused at cruising speed when it never had before. more then hardwear id say the biggest difference is weight in the boat. I tossed a cooler and the wife outa the boat and i ran 10.2 mph faster on the gps. I'm sure if i was really horny to break into 100s i could strip shit like my back seat, radio, all the extra stuff in the boat and run only a few gallons of gas and get there easier. is this is a river boat and takes us up and down the river almost every other weekend....many times ten to fifteen mile trips to find beachs or visit the dam.

How bout a 2-3 mile run at 5500-6,000 rpm?

I've ridden in fast large boats and the ish is boring as sin. I want to feel like i was shot from a cannon not cruising down the 10 doing 80

First off, Tim and Paul are two great guys. Tim helped me so much with my Southwind, and Paul with boat motors. Great guys that really don't expect much in return. I hope to repay the favor some day.

And Mr HB, is that a dis on the family wagon?

Welcome to the convo a week.later dan. No I was reffering to offshore lake boats that take ten minutes to get on plain yet run 100. Ur boat moves good for a bigger heavy boat

Ya its a proven fact according to that one guy swtd=slow

Twin turbos would be a nice touch on your ls so u can go slow too kevin

Nice looking ride. Solid work

well make it happen, I know the cp regatta last year is what lit a fire under my ass to build a new motor.... I just dropped off some stuff at B1 Racing to be tweaked .........ooooooooooooooooh blender
