V-Drives are efficient enough to run with pretty mild HP right ?? If anything, us Jet guys need the extra ponies for our un-efficient jets!! Just wondering why you guys are so speed hungry.....that and I'm jealous you guys go so fast. :D

Just wondering why you guys are so speed hungry.....that and I'm jealous you guys go so fast. :D I don't think its really the speed, at least not for me. I like that "better hold on" rush of acceleration. But thats just me.
The reason I am doing it, is so I can pull big ass gears and cruise at 60mph at 3000 rpm, or so... Not to mention they are the best mufflers made, and they look really cool...
So the engine will idle like a kitten until you nail it.

I have an engine with the " mufflers " for sale, as well as a brand new Gentry turbo kit (manifolds, intercooler, turbos and water cooled housings, and carb boxes)
I may separate the engine if someone wants the turbo system off of it.

This is why I have a v-drive
Fast enough to push the skin back on the face of a very fit 9 year old with the throttle barely cracked. :D
No Turbo, just a small blower.

Some idiot did some poor planning and scheduled his wedding that weekend. So I guess I'm out.
Damn, sorry to hear that. Anything else planned?
Well the boat is scattered across the shop right now. But I will definatly be at CFW for fathers day.
Hey Kindsvater Flat, is that you in the pic ? you look EXACTLY like my cousin mike!!!!

Hallet19,
Then maybe you need to get yourself a v-drive...if you really are that jealous?
Or fix your jet's lame setup so it's more efficient. Shit or get off the pot so to speak.
So put a v on that Hallet of yours and see what happens? Don't blame me if the conversion is less than thrilling. Hull weight and all. And when you do upgrade to that efficient v-drive, look me up and I'll race you :D
83.6 mph jet with a mild BBC...
How many v's do that? Still wondering...
jer
I'm assuming the conversion is not that thrilling ??
Hallet19,
Just trying for a rise out of the v-drive guys. Still fishing for clues on how fast a typical 400 hp lake v-drive goes. Not many willing to offer. Very tough to get numbers from this crowd.
I do believe v's are more efficient than jets. But I'm also thinking a well setup and blueprinted jet can come close, with the added benefit of no transfer case and no prop on the bottom. Of course top speed depends on hull and weight. But a lot of v's are small light-weight flat bottoms from what I've heard, so factor that when you look at top speed. Your Hallet hull maybe heavier?
My jet may compare to those light-weight flat bottoms in hull weight and somewhat in drag, but I go 83.6 mph with about 400 hp. That in a lake boat with stereo+. How many 19' lake v's can match this? I know some v's out there with mild BB's that don't. And some do. No matter the drive, a good setup and hull can make all the difference. So don't judge jets too harshly based on what you got now.
jer
jer just take your speed and add about 10-20 mph for a vdrive with equal power. there, how's that?
:D :D

jer [/QB]I agree, what I see running around in vdrives that are for recreational use are not that fast because only 1 in 20 guys know how to set them up right. With jet boats only 1 in 50 guys knows how to set them up right. It seems like everyone (including me) wants to compare their boat to a similar race boat that has run real fast and that is never the case in reality.
If you want to see what the ET or speed difference is between a jet and a vdrive in a well set up drag boat with a similar engine you just look at the record books.

Mine v-drive is REALLY fast. Just Check out my GPS.
http://www.saber.net/~atthefarm/fold...s/topspeed.jpg
Rex, not good enough...I wanna see real 18-19' lake v-drive GPS's and rpm's. 10 mph + my speed, maybe?? I'm thinking a stretch. 20 mph + my speed...dream on! I've been around hot boats for awhile. I already have Info's and Sangster's numbers, thanks guys. :)
BTW, I noticed you stock liquid-filled Autometer 0-35 psi gages. I'll be ordering two to answer that big block pressure drop question. I rarely forget a challenge... :D You remember?
Unchained, you have a good point.
Jetters and v-drivers as a group may differ in motivation and level of setup. And comparing drive types; between hp, hull weight, drag and setup...setup is the hardest to pin down.
Your link....race results filter out a lot of variables, but stray from my original question...the typical lake boater.
I wanna know how a typical lake v-drive compares to a typical lake jet drive for top speed? With actual results. Assuming both drives set up well, and both hulls 18-19 foot, and both mild engines. Say running on 91 or maybe even 89 octane (dock gas - as in lake running) with a pax, stereo, cooler, anchor, etc...all the usual lake thingy's. I know what this means to jets, but v's??
Though jet boaters seem ready to share top speed GPS and rpm, I've found very few lake v-drivers sharing the same info. Why is this? Are they so fast they don't even care? Unlikely. I've found the faster I go the faster I wanna go...and am happy to posting speeds. So how about it?
Just wondering,
jer
Kindsvater,
Ya ok. :D
Don't mean to put you on the spot, but from the (old?) video/audio, I'm guessing less than 5k rpm? Your have what looks like a dual carb tunnel rammed mild BB v-drive...not race setup. I'd be surprised if you're seeing low to mid 70's? But I don't mean to dis your rig...I love the looks. Just wondering...what do you run?

jer Mine runs honest high 70's, once I hit 81 on gps. It has 12% gears with a 3 blade prop. Its strictly used to pull the kids on tubes and skiing. Top rpm is 6700 in choppy water. BTW the boat/trailer full of fuel weighs just over 3600lbs.
Thanks Kindsvater,
I recognize that Etrex! BTW, "WAIT... TRACKING SATELLITES" with no compass direction a dead give-away. As opposed to "READY TO NAVIGATE" Accuracy 16 ft:
http://users.lvcm.com/lvjetboy/Ready.gif
Above my run with two (heavy) pax...lake trim.
Mine runs honest high 70's, once I hit 81 on gpsThat's really what I'm wondering. Your 6700 rpm seems high from audio, but hard to tell and just a guess on my part...how that compares to a jet I don't know. Seems props way different in the rpm vs. speed department. I run 5000 rpm at top speed on "small" B Berkeley impeller. Regular size is A...similar to a small prop? I donno. With two pax that's 79.6 mph at 70 degrees, as you see above. With one pax (the driver me) that = 83.6 mph. A 4 mph gain with 160 lbs less.
Your engine details? Do you have a guess on hp? I'm thinking about the same as me (400-415)? I have a 454 tunnel ram (twin carbs as you) with 9.5 to 1 compression.
BTW Kindsvater, I appreciate you sharing numbers. And from reading your other posts I think you're cool. I'm a numbers guy and always searching for truth...sometimes as a challenge, sometimes not, controversial at times, but always searching for truth...

jer This is serious, All BS will have to be put aside. You'll be bursting the "V-Drive advantage" bubble.
The guy I bought my JJCheyenne from sold me the jet boat to buy a Sanger flatbottom. He ran 100 mph in the jet and put the same motor in the flat and ran 89 mph. I seen it run.
He told me he was selling the jet boat because it was boring to drive.
???????
I guess controllable and stable must be boring.
:D
I've seen some hydros out on the water while boating and they were supposed to run fast but there was never water smooth enough for them so it was a moot point. Same with flats. It's always, "if it was smooth I could really run".
:rolleyes:
Not sure Unchained. Just wondering.
Of course there's the thrill factor. Magnified by the inherent instability of the flat bottom design. Controllable is a bit boring as opposed to unstable...I understand that well. Not a good measure of speed or efficiency. My hull is unstable in big water compare to say a deep V-bottom hull. A big V hull's comfort point certainly higher than mine depending on water surface conditions.
Regarless of hull designs, I still lean towards v drive's as more efficient from the lack of pump housing water friction. Not intending to rain on the jet parade, as I appreciate the advantage of a jet. Just wondering how much?
Questioning the numbers at this point...
Any takers?

jer you do have to admit it got your attention jer... :D :D
LV , and unchained take this crap back to the jet boat forum or bench racers! Unchained your boat goes 100? How do you know that? I seriously doubt any 100 m.p.h jet boat is gonna be out in rough water. Just ask BBT his jet boat is light! Also the won who beat BBT only ran 104 at ming last weekend. So no frickan way! Sorry to burst your bubble but dont beleive everything the seller says. eek!
Oh BTW Lv go to N.J.B.A.net and compare the #s between ski jet and ski flat this should answer your question! Have a good one wink
Flyte Risk,
I'm not talking about BBT or his first performance. I'm not talking about NJBA or any other sanctioned race. Race results a function of $$$, reaction time, experience, luck and other factors. I'm just talking about typical everyday lake jets and typical everyday lake v-drives. I don't drag race my jet in sanctioned events and may never. Also I seriously doubt any jet or v-drive will run 100 mph in rough water...copy?
Seller? What the h*ll does that have to do with anything? I'm just posting my question to the v-drivers in the v-drive forum...seems appropriate to me. Not sure why you think this is "crap" but all opinions welcome.

The 534 mph was in flight on southwest airlines. As far as my motor goes its 12.5:1 with stock 906 heads, no port work. Carbs are 600 holleys with vacuum secondaries. As far as the movies go, none of them were wide open throttle runs. I think I do have some but will have to edit a tape.
Thanks for the info. Kindsvater,
Seems like 12.5:1 is really high for gas these days, but I'm no engine guy. I've got stock LS-6 heads. Also got dual Holley 715's w/vacuums but I pinned them for 1 mph more top speed...not recommended from what I've heard. I think your 600's a better combo. The secondaries opening on launch sound cool though.
I'd love to see your wide open videos...
jer
That's sweet Kindsvater. Hadn't seen the hopping video. Nice! I think I read you got some engine upgrades in the works? Not sure these days (of my memory) that is. Wishing the best from a jetter...
jer
her ya go 60 mph 3000 rpm. Are you talkin about a stock berkley vs a stock v-drive your going to gain 15+ mph
Hey LV, I don't know what my first flat really ran. They didn't have GPS back then. And we didn't have radar guns as we spent all our cash on gas, grass and chasin ass :D if you know what I'm sayin. (Early 20's was so fun)
For a lake jet it sounds like yours in an above ave. deal to me. You must have your set up dialed in for what you've got.
What you otta do is bring that puppy to the Needles bash. Needles is not that far from you. There will be flats & hydros of all shapes and sizes. Lots will be typ. river deals. You should come on down and see how you stack up with a few of them. I'm not talking pairing up with the blown alki guys. Maybe pair up with a few that have single carbs or a tunnel ram set up like you have. All in fun of course.
Plus, I've never met you yet and would like to. Hey, most likely my boat won't be done so I'ed also like to mooch a ride in that deal of yours too. I'll by the beer and gas. What do ya say?
