[@charleshenshaw9099]

I don't know about Jet boats, but I know about race boats with outdrives and you don't limit the rpm with the camshaft. You use the cam to control where you want max hp and tq. You control the rpm with the propeller, through size and pitch. I hope that the 4th try is the charm. Cheers

[@sneezinhatch]

A jet boat is similar to a turbo the engine turns a pump that compresses water through a pump and like a turbo you can only flow so much or it will not perform correctly or you will over speed it and blow the pump. There's a video that compares all this but that's the short version of me owning a speedboat with 2 572s and 10/71s also a wake boat with 2 basically supercharged Corvette engines max rpm is 6200/ jet 5500/ 42 fountain

[@wingracer1614]

That's the whole point. The cam is laying over before 6500. It makes good power at 4500 but falls on its face before getting to 6500. He's not trying to limit rpm with the cam, he's just saying what it does past 6500 doesn't matter because it's going to be limited to 6500 max or it would blow up the pump. Now this is just speculation on my part but I suspect the problem is that 6500 number sounds really low to his drag racer mind so he thought less rpm means smaller cam and that just isn't working.

[@AB-80X]

How many race boats have you set up? I come from a family of European powerboat racers, and I have set up boats with everything from Bravo drives to Arnesons. We do not limit the RPM with the prop. We create an engine that makes the maximum power we can, and the longevity limits what we can do. That means we shoot for a specific RPM, just like Steve does here. He wants an engine that makes peak power at 6500 rpm. What we would normally do is this. We would cam it ever so slightly above the desired peak RPM number and then take away a bit of timing to create less cylinder pressure and thus move the peak power RPM down a bit. Then we test props until we find the prop that sits at the RPM we designed the engine for and carries the boat as best as possible. Powerboat race engines are typically built to run 7500-8000 rpm if you use the old school V8's. It's a bit of a different story with modern turbo engines, being it from Merc or Sterling for example. They often run more like 6500-7500 rpm. At any rate, you prop for the boat and the RPM, not the other way around. If you build an engine that peaks at 6500 rpm but want 5700 rpm for a pleasure boat application, not only do you end up with an engine that is very sluggish out of the hole, you end up with an engine that knocks way too easy, and the valvetrain will be needlessly aggressive. Why build a 1200 hp engine that peaks at 6500 which needs a solid roller setup, when you can build an engine for a pleasure boat that will peak at 5800 using a hydraulic roller setup, and not have issues with water reversion? And why build a race engine that peaks at 8200 rpm if 7500 is what you want?

[@recoilrob324]

All I know about the old Hemi is that you have to watch the overlap with high lift cams because the valves will hit one another. So besides piston to valve clearances you have to allow quite a bit of clearance between the valves which really limits the overlap you can run. So...I'd begin by determining how much overlap the heads will take before they clash, which then will determine what kind of lobe separation you need to run. How much lift the springs and valves can take and the acceleration and deceleration ramps will help determine the duration you can run with the limitations we've already mentioned about the overlap. I'm wondering if trying to spec the cam for max power at 6500 NA isn't maybe a bad idea seeing as it's going to be blown so it won't need nearly as aggressive cam timing to fill the cylinders well. More power to you Steve! I'm impressed that you took on the Big Black Hemi in the first place....and carrying through on it as you are shows a lot of spine and conviction. Good on you man!

Your wisdom outshines most, if not many of us Steve. I would say this isn't your first rodeo with a Hemi, but perhaps not at this size/scale as this thing should be larger than even your TopFuel spec, but suffice's to say, everything has a learning curve, and I'm blown away at your ability to archive the journey.

[@edwardschaider7937]

Steve, I feel for the pain you are going through. Over a half century ago I, and a lot of other people, were attempting to get the then relatively new 426 Hemi to perform in the mid and upper engine speeds. Long story short, the engine wanted a surprisingly tight LSA (104˚), as much lift as we could get with the then basically stock valve gear (0.750"), 296˚ of duration at 0.050", and a lot of valve spring, spring rate to control the whole mess. I think your Big Black Hemi will respond to similar specs. I would suggest you want a 104˚ LSA. I think the engine would actually like a tighter LSA. However, I suspect you are going to be limited by intake valve to exhaust valve clearances during overlap. If you have the clearance, I would go as tight as a 95˚ LSA, valve-to-valve clearances permitting. However, I suspect that will potentially be physically impossible. I would look for a lobe duration @ 0.050" lift that was between 290˚ to 300˚ and favoring 300˚. I would be looking at that duration for both cylinder filling and also smoothing out the valvetrain dynamics as much as possible for reliability and service life. Both in the reliability column and in the cylinder filling column, I would shoot for a 0.800 valve lift. With today's profiles and springs 0.800" lift is much more doable and reliable than in years gone by. I think the engine will likely be capable of significantly more engine speed than 6500 rpm. That said, the jet drive is still going to be the limiting factor for engine speed, as you have already indicated. Additional engine speed availability, notwithstanding the power at 6500 engine rpm, should be fairly impressive. At 6500 rpm with a Ve between 95 and 100%, the engine should be processing between 113 and 119 lbs of air per minute, which translates into 1130 to 1190 HP n/a and properly fueled. Your pull produced 969 HP but laid over on top, which is saying you are running out of breathing, i.e., camshaft. The tightened LSA will improve cylinder filling, while the extended duration will aid upper rpm breathing (which you already know from SMX experience). When you put the blower back on the engine, the HP will be essentially linear with the BAR of boost you add to the intake. 1 BAR. would be roughly 2260 to 2380 HP at 6500 before accounting for the power to drive the blower. 3 BAR of boost would look more like 3300 HP at 6500 rpm again give or take some loss to drive the blower. My suggestion: Duration: 290˚ to 300˚ @ 0.050" LSA: 104˚ or tighter, clearances permitting Lobe lift: 0.800" at the valve Springs: 350 lbs per inch spring rate, higher is potentially too hard on the valve train at startup.

The 3 BAR numbers are, in fact, PSIA, and the 1BAR PSIG (which wasn't ID'd) is, in fact, 2 BAR PSIA. Soooo, n/a (1 BAR PSIA) should approximate 1150 HP. At 14.7 lbs of boost PSIG (2 BAR PSIA), the engine should approximate 2300 HP, less the power to drive the blower. At 29.4 lbs of boost PSIG (3 BAR PSIA), the engine should approximate 3450 HP, less the power to drive the blower. I am not familiar enough with the compressor you are using to know if it is capable of processing that much air mass. If it is, those should be pretty realistic numbers. If it is not then the numbers will become proportionately lower.

[@edwardschaider7937]

Man, am I clumsy - arrrrgh! Additional corrections: The 350 lbs. figure for springs is not the spring rate; it is the seat pressure I would be looking for. The spring rate I would want to see would be between 550 and 650 lbs per inch which should keep your open pressure somewhere around 830 lbs on the nose. With the rockers and valves you appear to be using, that should be adequate to maintain good valve train dynamics at 6500 rpm.

Thanks for the great content as usual! We all learn a ton from your videos. My thought given the displacement, RPM ceiling and boost: .960 intake lift at 285* duration @ .050 lift .965 exhaust lift at 295* duration @ .050 lift 128 Lobe Separation Looking forward to the update!

[@rodneygreen3388]

Just a somewhat educated guess. I never worked on anything gas this big. 632 was about it for me back in the day. 903cu and 6500rpm Intake 295*@.50 .875 lift 125* center Exhaust 315* @50 .890 lift 116 lobe separation

id think you are somewhere in the ballpark. hard to be accurate without more info.

[@rodneygreen3388]

Left im actually thinking I may be in the starting cam range. Not in the finishing cam range. I basically took known specs for a pretty radical BB cam and pushed them out some for the added Cubic inches. Then cut them back a little for the relatively low RPM.

[@johnnickerson6522]

$20,000?! Even if his burdened labor rate is only $100 per hour which is really low, 600 hours would come up to $60,000. Another, say, $20,000 for 4 cams and you're well on your way to a hundred grand. By the time he delivers this engine, I'm guessing Steve is going to be, at the very minimum, $50,000 in the red. Probably a lot more than that.

[@artyboy92]

I appreciate the candidness of your videos and explaining the issues that go on. I spent a few years working for a shop that built cars and we found ourselves in various similar situations where there were issues ranging from it being our fault, part supplier fault, outside contractors at fault and even the customer at fault. We were a small shop and you're bang on correct about when you have to throw chargable hours in the trash for nothing it puts a huge strain on the entire business and the stress of that ultimately was why I left. It's tough because the customer sees their bill in the tens of thousands of dollars and thinks we're making money hand over fist however the reality is the margins are so thin. Plus the amount of youtube videos that leave out the problems and make everything look streamlined and easy don't help with their expectations.

This is why we love you Steve. Your dedication to clients and quality. This turned from can you make me this odd engine to full on blue printing and engineering new engine all together. All that with all development costs that come with it. Investing in something that might not be ordered ever again but still doing it right way. I wish all of the guys that will need such engine are going to order from you guys and this money will not be wasted. This is also testament of the quality and performance of the SMX. Even bigger version of the SMX is still a lot smaller than this engine and it makes same NA power. Sure it does 3K rpm more but still it is amazing that it can do that at all. This all just shows how complex things are and that good result does not just falls in your lap. Sure sometimes you t is easier but once outside the comfort zone only things that help is knowledge and experience. Amazing videos. Not that many people would show this at all. Even if they would do and stick with this they would keep it as the trade secret and wouldn’t risk to show them self suffering. It takes bigger man to do this. Good speed Steve.

Steve, I commend you for being completely transparent, you’re showing integrity. There are a lot of people that are saying negative things bc of what happened with cleetus. I have been a fan of garrets literally since he started his channel. With that being said you’ve been completely transparent and have not hidden one thing like most engine builders are not on KZbin,, these people that are watching the videos have no idea that proline and any other engine builder had just as man problems out of their engines especially when it’s still going through R&D which the SMX is still going through let’s be honest. It’s at the very end of R&D where small trivial issues are being sorted the only way to get the Research is to have race teams beating on the engine to find failure points..
