Twin-Turbo Jet Boat Holeshot Secret Revealed! Finnegan's Garage Ep.106

So many of you have wondered how we are making the twin-turbo jet boat sit still while revving the Hemi and then launching it that we decided to drop a new video explaining why Game Over looks like it has a trans brake. It's true, this jet boat has no brakes, no seat belts, no transmission and yet we still treat it like a fast drag car when we spool up the turbos and unleash the twin-turbo Hemi on the water. How is this possible? Well, we'll show you.
In this video we explain how we redirect the water coming out of the jet drive to the sides of the boat, which enables us to rev the engine to over 4,000 rpm and then drop the hammer and take off like we've been shot out of cannon! and just for fun, we lined up 100 ft behind my neighbors PWC for a short drag race on our local lake! No surprise, we blew past the PWC like it was tied to a dock. It was still fun though.
Want more info about the jet drive parts we are using? Give B1 Racing a shout at (949) 294-1394 or Henry Morris at 302-530-1522.

It'd be interesting to see a race against one of those turbo jet skis then run 130mph.

This may have been asked and answered but I missed it, if so, sorry. Do you have the pop off safety valve wired so if the engine suddenly stops running for whatever reason, it activates to release the water? Reason I ask is the way I understand your description, you are activating it and you said that if the engine were to lock up for some reason, it would kick the stern up and the bow down therefore turning your boat most likely into a submarinewho's crew had just been give the dive, dive, dive, order.

The video at 8:39 is why you build a jet boat. That is an incredible burst of power in a small area... that jet drive is amazing... You gotta open it up and let it drink!

That "race" was just adorable!! LoL 😆 quick question, when you were showing the jet right at the very end there i noticed there was all kinds of water venting out of the pop off before you had hit the actual button. Is that normal or is that the excess water that just cant make it through or somthing like that? The pop off is basically a blow off valve that blows off water instead of air and you control it instead of vacuum from the engine in a sense ya? Maybe? Idk...lol

Did you wire pop off valve solenoid to a safety relay or trigger of sorts, as a safety against the motor stalling/seizing? Something that would auto open the valve in the event it stopped seeing engine RPM but ignition was still on. Excellent build. Hope you get that scoop/cavitation issue solved.

Make a bigger intake? Or move it more forward on the boat. I dont see that the boat is struggling to take up water (at least from the clips you are posting)

The Victoria Cross (VC) is the highest and most prestigious award of the British honours system. It is awarded for valour "in the presence of the enemy" to members of the British Armed Forces. It may be awarded posthumously. It was previously awarded to Commonwealth countries, most of which have established their own honours systems and no longer recommend British honours. It may be awarded to a person of any military rank in any service and to civilians under military command although no civilian has received the award since 1879. Since the first awards were presented by Queen Victoria in 1857, two-thirds of all awards have been personally presented by the British monarch. These investitures are usually held at Buckingham Palace. The VC was introduced on 29 January 1856 by Queen Victoria to honour acts of valour during the Crimean War. Since then, the medal has been awarded 1,358 times to 1,355 individual recipients. Only 15 medals, of which 11 were to members of the British Army and four were to members of the Australian Army, have been awarded since the Second World War. The traditional explanation of the source of the metal from which the medals are struck is that it derives from Russian cannons captured at the Siege of Sevastopol. However, research has indicated another origin for the material.[4] Historian John Glanfield has established that the metal for most of the medals made since December 1914 came from two Chinese cannons, and that there is no evidence of Russian origin.[5] Owing to its rarity, the VC is highly prized and the medal has fetched over £400,000 at auctions.[6] A number of public and private collections are devoted to the Victoria Cross. The private collection of Lord Ashcroft, amassed since 1986, contains over one-tenth of all VCs awarded. Following a 2008 donation to the Imperial War Museum, the Ashcroft collection went on public display alongside the museum's Victoria and George Cross collection in November 2010.[7] Beginning with the Centennial of Confederation in 1967, Canada,[8] followed in 1975 by Australia[9] and New Zealand,[10] developed their own national honours systems, separate from and independent of the British or Imperial honours system. As each country's system evolved, operational gallantry awards were developed with the premier award of each system-the Victoria Cross for Australia, the Canadian Victoria Cross and the Victoria Cross for New Zealand-being created and named in honour of the Victoria Cross. These are unique awards of each honours system, recommended, assessed, gazetted, and presented by each country.

Couldn’t you add a hydrofoil to the bottom aft so it keeps the backend planted and rams water into the jet drive intakes simultaneously?

You should consider ditching the jet for a twin v drive system. I run that in my hydro. So much more effective plus you have steering after you cut the throttle. Also you might wanna consider some chutes soon.

It's pretty amazing to watch the drive and watch the steering cables slack up I'm guessing from the force being put on the hull. The side x side shot was excellent.

You could add another valve and path to that neutral bucket to effectively get reverse. Obviously you would have to be creative and make one. I can see several ways to do so. I am sure if you wanted reverse you could make it happen and still have your neutral bucket work about the same.

3" outlet on your jet drive is why it accelerates like mad and runs out of top end. You can only cram so much volume through a 3" hole before your cavitating the water pre-pump. I think this is signified by the short rpm burst when you open the neutral bucket, the first .5 second you see the jet stream drive backards and the engine increases rpm momentarily then decreases back down when the water volume is sufficient to supply the pump

I'd suggest a solution to your jet pump starvation but I'm just some dude in the comments section. Just remember Bernoulli's principle applies in any fluid. Creating a raised area pre-flow to the intake mouth will induce an acceleration in the fluid medium and a drop in pressure over the obstacle. Additionally, if placed correctly the fluid will have an accelerated velocity and lowered pressure in relation to the surrounding "atmosphere", i.e., water which might more readily force the fluid into the intake. Or in other words place the upper chord of an airfoil/waterfoil in a semicircular area in front of the inlet and allow the fluid dynamics to work their magic.
