30' Velocity Testing...
 

Got a new set of props a week ago and was able to get out yesterday and test.

Brand new stock 28" Quad IV's, 1990 30' w/ stock 502 MPI's. Stock Bravo I's turning out.

Roughly 1/4 tank of fuel, 3 adults, and hotter than balls yesterday morning.

Got a best of 77.3 mph... Motors are about 100 RPM's apart, one at 5000, other at 4900. Handling was great though. Boat felt aired out and even felt the tail end dancing around a bit with the tabs up around 2-3.

Happy with that considering the weather and 3 people. Really want this thing to run 80 though... :evilb:

Try the Bravo's, had a Quad IV on my 280 and the Bravo handled better, better midrange, top end, everything.

Each model seems to favor a particular prop. Although on the bigger single engine hulls, some guys prefer Bravos and others QIV's!

Hydro QIV's spinning IN is the most common set-up for the 30/32's hulls. Best top end with very solid handling up to 90 or so.

But unlike my 32', my 39' likes Bravo's better due to the extra blade area!

Any pictures of the boat? Id love to check it out.

Sure. ;)

Jeff, it really is looking good.
Time to change the reg stickers?

Thanks Rob! Yeah, that last pic is when it first got here. Although I did remove the NY stickers, I still haven't had the new ones cut... doh! :lolhit: :poopoo:

Beautiful boat, im looking at 30's as well. If you dont mind me asking, what should I expect to pay for a boat as nice as yours? Thanks for posting up pics, she sure is a beauty.

Awesome stuff Jeff. Remind me to look the other way when you pull up beside me ;)

There is a couple for sale but i can't vouch for condition. I would say for a decent one it's gonna be $20-30k. Mine cosmetically is damn near perfect. The nice ones are getting harder to find.

My 30 has HP500's, 1.5 bravo xr's with speedmaster lowers turning in. Ran 84 with 5 blade 15.5 x 28 hydromotives and 94 with 15.5 x 31 5-blade hydromotives at 5300 (limiters) with 3 guys and 1/2 fuel on flat fresh water. I think she has more in her as we ran 90 with half fuel and 6 people on board. I just need to get some 33's or 34's and see if we can turn them.

Call Steve up at Velocity and ask him about your set-up...nobody on earth knows how to set up a Velocity better. You're pretty close to 80, some good tweaking and you should get there!

Did you guys ever weigh your boat once completed?

No, I haven't had a chance to do that. Would be interested to see though!

Ditto on calling Steve. The 5 blade props are needed for high x-dimension or running "shorty" lower units. For standard drive height set-ups, 4 blades work just as well and are easier on the prop shaft.

Thanks! I've talked with both Steve and Kenny, and got a few tips when the boat was delivered. Actually had the boat delivered to their shop so they could put their eyes on it.

We went through the basics...drive toe, verifying indicators, prop selection, etc.

Been considering selling mine... only been out 3 times this summer:( Had it 6 1/2 years now. Never had anything that long but the wife.

Maybe only 3 times this summer, but you did more boating in FL last winter than I did all year, and I live here.

I'm wondering if i seriously need nose cones now, am I not trimming it up enough, or what exactly I need. I have 540 hp - 540 ft/lbs small blocks turning 30 pitch bravo 4 blades to 81 mph.

I have the Drives trimmed to 7-9 (conditions depending) and the tabs 3-5 (conditions again) on the mechanical indicators, so they're is barely any hull in the water and only enough tab to stabilize the "pad walk" (as I call it). If your running 94 mph with HP 500's really curious as to what I'm doing wrong.

Hull is a Regal Velocity 30', built in 1989.

Might need to email Steve Stepp it seems.

I definitely recommend nose cones over 80. I added a Hydro-Motive nose cone to my Bravo 1 and the difference is huge, prop bite is much better when running more trim. Handling is much better also, I'm running 90 in a single engine 280.

Trim and tab sound about right. My guess is that you are over-propped for your engines' power-curve. I would assume you need to spin the SBC in the mid to upper 5,000's range to get that kind of peak power. At 81 MPH with a 30" pitch prop you can't be turning anywhere near that unless you have huge slip. Nose cones generally don't add speed in the 80 MPH range so I wouldn't be too hopeful. If you can't increase speed with smaller props then you're likely down on power if the hull is otherwise good.

Turning props in or out?

What RPM's are you turning?

Is this the teal boat that was in Canada?

Just curious what is all done to the 02's? Exhaust, water pump deletes ect?

Yes the Teal Boat in Canada, bought it last year

The little small blocks pull 500ft/lbs from 2500-4900 RPM and peak 540 ft/lbs at 3800 and don't drop below 500 ft/lbs until 5100 RPM. Peak HP is 542 at 5500 RPM. I first thought I over propped the boat myself but it pulls way to hard and comes out of the hole way to easily to be over propped.

Props are turning in and RPM is about 4800-4850. I'll get a chance to get back to the boat and off of Base in Two Weeks.

82 MPH is the best I've managed to run at 4850 which I believe worked out to 11% slip. I have never pushed the drive trim past the mechanical indicators, but I will give that a go. I have not come close to blowing out the props at this speed, and I know the motors will pull harder.

I've pulled labbed 30 pitch Maximum Props to 5100 RPM and though they were much smoother and stay hooked up better in turns, they were not any faster even with the extra RPM's. Felt like a little too much stern lift and really made the boat wander on the pad and I had to drop the tabs much more then with the 4 blade Bravo's to keep it under control.

Now that I'm sitting here thinking, I'm wondering if the flat torque curve of the small blocks won't let me pull the RPM I should as it's pretty much level the entire curve rather then climbing, or if the lighter weight of the small blocks isn't letting me trim enough of the boat onto the pad.

More drive time needed haha.

I'd think with the lighter weight the boat would have more natural lift and be more likely to get up on the pad with less trim.

Have you tried spinning out rather than in? Mine seems to settle in better spinning out, and I can keep the tabs around 3 with no porpoise.

Might be worth trying a set of 28's, just to see if you can get the RPM's outta those small blocks.

Have you checked your indicators to make sure they're accurate... actual trim matches what the indicators are reading? Also, the toe on the drives?

Indicators are bang on, I just re did all the cables and re adjusted everything this year.

The TOE of the drives I have not touched. It was set up by the previous owner and his marine mechanic, name is not coming to me at this point when they put in Imco External steering, it previously ran a best of 92 mph.

I am looking for a set of 28 pitch props to borrow, but there is only about 3 boats on my river running Bravo's.

Nice 30 brother 80 MPH is good but to get the full Sh!ts 95-100 MPH will put it in the swim trunks. :):poopoo:
I have learned instead of changing props just buy the biggest size then add Horse Power to get the speed you are looking for.

I have a 32' Advantage Victory going together hopefully this winter if things work out with 556ci big blocks. It should dance to 100 mph.

The Regal was a boat to replace my fathers Chris Craft, as a gift to me for graduating college. The 427's were pulled from the Chris Craft, rushed in for a Poker Run and then pulled again after for a refreshening this winter to make sure they were ready to go for me.

At his passing this year I've taken over both boats and want to complete the Victory in his honor, just lacking the knowledge tremendously that he had.

So I'm trying to figure out the Regal completely with out putting anymore moeny into it. I'm happy with the boat and love how flat it flies when I get running at 81 mph.

Just trying to squeeze the last bit from it as cheaply as possible.

Also try to find a pair of 26" Hydro Q4's. They are roughly the same pitch as 28" Bravo's and typically add a 1-2 MPH on a twin and will spin your engines a little faster. The factory equipped the 32's with Hydro Q4's. Best of luck with your project.

26 pitch hydro's eh. Hmm I was told they were roughly the same size but the hydro's were just faster on the top end and worst everywhere else, good knowledge, thank you.

I will keep my eyes peeled.

Yes those will wake her up:evilb:

How is that mph possible? I know v hulls are fast buuut.

One word VELOCITY:evilb:

Here's my sh!t getter... :evilb: :evilb:

It'll run over 100 and get there in an instant.

Nice shot! Exactly how small is the pad on the Allison- must be pretty short if we can't see it in that picture. :cartman:

It's longer than it appears. Probably 4 or 5 feet and about 11"-12" wide.

Don't think my truck could get it up that fast on the highway, so only other place to do it is the water:lolhit:

3 of us were in the boat...I throttled and Steve Stepp himself was at the wheel! Can't wait to get back up to Lake Monroe and try for triple digits.

I have been lucky enough to be out with the Poppa boys a few times, Still Crazy runs real good with stock HP 500 carb motors!

Back when Steve built these in the 80's , a standard 30' velocity w/420's would run 85 mph . Fast foward 25 years and put 500 HP's in and new prop tech , then those numbers seem reasonable . Now imagine what the results would be building a new light weight one with 525's :evilb:

Stupid question on this.

How are the 26 pitch hydros as fast or faster as a 2 pitch larger size bravo at the same RPM?
