How to smoke a v drive

[BrendellaJet]

My dad was boasting today about how much faster his 66 Lavey Craft v drive is going to be than my 77 Brendella Jet. He has a reworked Olds 455, it makes about 400hp. I dont know much else about it except that it has a Casale v drive unit in it and through transom logs. My 454/Jacuzzi 12WJ/B combo dose 60 right now. The only upgrade to the motor is a mild cam and headers. I am upgrading to a Performance Distributors HEI, and installing a new electric fuel pump this week and am hoping for 65(it starts to miss at top end around 5grand or so and timing/tuning haven't fixed the problem. I know I dont give you many details, but thats because I dont know them, and I am willing to do whatever it takes to beat him. A pump rebuild is scheduled for this winter( it gets out of the hole great! but I want to eliminate any week links), and I am going to go through the motor and check things out to plan more mods. He hasn't but the boat in the water yet, so I dont know how fast it is. What does it take for my jet to beat his v drive? How fast will his boat be? I have 4 thousand to spend on it, although, I could probably squeez an extra 2500 if necessary. What speed is too fast in my hull? Thanks for your response!

Dad has an oldmobile? :p Speed is not how you beat Dad, DURATION is! Make Dad keep that Oldmobile WFO for a couple minutes and you'll win! He'll slow when he spinS a bearing! :D

Buy a faster V-drive than Dad's :D :D

Buy a faster V-drive than Dad's :D :D Both funny responses, but since I helped build the motor, and I like my jet, I need some real alternatives. Anybody out there have a reliable setup that smokes the v-drives? Please help.

Anybody out there have a reliable setup that smokes the v-drives? Please help.Everything is relative... Even my Spectra 20 ran away from a V-Drive on the go the other weekend at the river. Never mind the fact that it was probably a mild small block powered V-drive :) I can point you to quite a few Jetboats that will outrun a good deal of the flatties crusing the lakes/river. But then you take it up a notch and you have the guys in V'drives that can smoke some of the fastest jets. The bottom line is that there is always someone faster. If you build your jet to run a legit 70 on GPS, I'm sure there are more than a couple of V'drives out there you could beat... even more "90mph" jetboats that you would probably be able to pull. Who cares what the other guy is spinning, be it a prop or an impeller, if you race and he pulls you, you still lose. Regardless of whether it's a jet or a V'drive. The better way to go about your project is to decide how fast you want your boat to go. So go GPS dads V'drive, then build your boat to be 5mph or so faster and you've met your objective. Just realize that Dad will probably upgrade the V'drive to run 5mph faster than you and so the progression will continue.
Good luck,
Chris

Try a NOS system. Use caution the stuff is like
crack. You can get hooked real easy. Use your head a play with a 125 shot. Need to fix the miss
and have a good fuel set up.

[BrendellaJet]

Flat broke, thanks for the advice, I think that sounds like a good idea. I do not think my dads set up is maximized. He bought the boat and put a new motor in it, thats it. He hasn't checked out the prop selection or gears yet, so who knows. I have entertained the NOS idea. I have also considered a supercharger too. Last question, I have seen the boat races on TV and seen horror accidents about boats flipping over from getting too much air underneath them. If you are familiar with my hull(77 Brendella Bubble deck), how fast can my boat go safely?

V-Drives are probably the most efficient drive in boats, sorry to break it to you, guys cruise around at 60 mph @ 2500 rpm's and lots of guys can top even small blocks out around 70+mph which is difficult for a jet to get that speed. Pickle the load has a jet that runs almost 100 off the bottle and probably 110 on the bottle, but he has a new Ultra 19 Shadow tunnel hull with a twin carb tunnel ram 540 Merlin. It is rare a v-drive steps to him and wins but that is also a rediculous setup, 540 merlin is a TON of HP and tourque, and alot of $$$$$.

Where is the H2O?

[Hallett19]

or you go to lake martinez and boat in and around the sanbars where you can run in inches of water and your old man will need a good foot and a half. He will loose his prop and shaft in a heartbeat and you will be chillin the most at a sandbar, while he will be getting towed the most off of a sandbar :)

[Jungle Boy]

SuperV, How did you post that. Man, I just can't get it right. As far as the water; we came up from the right and tried to hook a hard left and just about made the corner, but ran aground cause I was going a bit faster than I should have. Those flood plains are a blast to rip around in.

[superdave013]

BrendellaJet, Good luck and have fun. Must be nice having a dad that's still into HiPo boating. If and when you wack your pops have him contact me. I'll fix him up with some larger gears! :D

I have a HELL of a deal on a supercharger! B&M 250 blower with superchiller, dual Holley HP 950's, stainless fuel lines, side saddle set up, K&N filter with billet holder - $4,000. All polished and in excellent condition. Makes 9lbs of boost (might be a tad high for your application, but a pulley change is all that is needed to lower the boost). Below are pictures of the motor it was on (made ~750 HP on a 502 with some other nice goodies). The B&M was taken off and replaced with a Whipple to fit under the hatch.

Dave.Not to be mean Dave but I would think that since you are a represenative from Aggressor Jets that you would have better advise then sabotaging the v-drive. I know it was a joke but man. I would have said contact me I will hook you up with what you need.

Can you imagine what that 4 grand will do to the v-drive.... HOLD ON!!!!

I HAVE NOT HAD ANY LAKE BOAT BEAT ME YET.

How to smoke a v-drive?
You would need one big ass bong!

This was discussed by Jim Wilkes (V drive Tech) and he stated that the IO was the most efficient drive.

[Bense468]

huhThat is what I was thinking.

It does our hearts good to see 2 of our 4 sons
involved in boating. We can hardly wait to go
on a family vacation. BJ (Brendella Jet) you have forgotten a thing or two. First you forgot to mention that this Olds is 1 of a few that was built by olds for high performance and put out almost 400hp from the factory. Second, an olds specialist(Dave Smith)has been our mentor. I am happy that performance boats still interest me but even more proud that they interest your grandfather and that he is able to do this with me. The problem with spinning the bearings has already been addressed so no problem. The Casale is setup right and the prop well lets just say it is in good hands. It's good to see that you know cheating isn't winning. You have a nice boat
and like one person said don't worry if I'm faster, when you grow up you'll buy a v-drive.
V-drives rule!

don't tell me old age and wisdom are gonna beat up youth and enthusiasm again.

[Moomawnster]

I have a 350 sbc in a 16 ft Tahiti jet and I do 60 mph easy ...planes out in 32ft ...like you said ,hole shot ...at least make him pass you down the lake somewhere ! I think the V is going to be tough to beat so youth and enthusiasm won't be enough this time ....only $$$$$ will prevail ! eek!

[Sangster]

It's not "jest" the high price of HP, it takes a boat that works properly.... eek! eek! eek!
