5:43 - They just get to an inefficient spot in the map. Well said Steve. Another reason why this happens is because as the engine (particularly in a large 540 CI set up like this) revs faster there is less time for the air/fuel mixture (whether it's the ideal ratio or not) to get in and completely fill the cylinders because the valves are open for less and less time as the RPM increases. Without complete cylinder filling Torque will start to flatten out/off and so will HP; especially compared to the same engine running higher boost levels. The feature/phenomena of Torque and HP starting to flatten out/off (on the engine in question) when incomplete cylinder filling occurs is not so evident on this engine when it actually starts to happen but Steve points out features of the phenomena including how low the RPM is when the engine is at it's ideal crankshaft rotational speeds, when he mentions how low the RPM is when; (i) the engine is at its happiest; (ii) any RPM higher equates to the engine not running at it's optional crankshaft rotational speeds; (iii) the optimal air/fuel mixture occurs (iv) the location in the compressor map; and (vi) complete cylinder filling is achieved. Great engine Steve. Jim Stanley Ex AMG Powertrain Engineer.
Stevie boy puts those HUGE numbers down all the time! Shares these amazing dyno pulls so we can learn and to promote his business. PLEASE don't quit the vids steve because of idiots! Thanks for the effort man.
Hey Steve you are a legendary engine builder your reputation speaks for itself. Tom Bailey car broke all records at drag week that engine spoke for itself. Oh by the way who probably left that comment was a engine builder from California let's just say his first name was Tom LOL
I am always blown away when I watch your videos. You and your team know their stuff, that is for sure. Aside from the huge hp numbers I am truly impressed with the Machining you do. I have been making chips as a tool and die guy for 30 years and that side of your work Deserve just as much respect as your huge horsepower numbers.
I have a street twin turbo big block in my truck that makes really big power , that is until I compare it to one of yours , but you supplied my current hydraulic roller and it has never ran better , thanks Steve , it doesn’t really surprise me that internet trolls would hide behind their keyboard and spew garbage at you as some people are just losers .
I like watching the pretty colors and the needles doing needle things, I personally never doubted you, it's not like you can fake what you are doing and have accomplished.
Mr. Morris... Let the haters hate because that's all they know how to do. Your workmanship speaks for itself. Not many engine builders are in this elite league of making power, reliably, all day long ! Thank you.
Glad someone finally said it: pressure is not necessarily proportional to mass flow rate of air. Its related but its dependent on many factors. Well done👍
Sir when you do these dyno pulls & talking about everything I'd like to hear what kinda motor it is the size & all what's been done to & maybe even that parts you've used. Someone like me could think of stuff I could do to what ever I'm building but in a smaller cube motor & think up different combos. Thank you for sharing ur knowledge sir.
My god, what transmission is gonna hold up to this monster. I want this in my street car so I can cruise around, but then dominate the track afterwards
if Steve says it's real it's real if anybody doubts it line up against his cars with the motor in it then you'll find out that you're lacking on power cuz you're not MSX powered
Very nice piece.... as you would say!!!! But!!!! Most people would say that a 2000hp turbo BBC is a very nice piece!!! So I think your pieces are just a little better!!!
Interesting and informative video Steve. Question. If one went with say quad Hart 88 or 94 mm turbos compared to the twin 110 Harts you have in the Wagon, would that make for a more efficient compressor map at a higher boost level? Just wondering.
As I call Steve, the mad scientist of boost in the dyno lab. I got into a argument with a guy over what your talking about with low boost and small ci bbc engines. He thinks everyone is crazy and that we should be running a min of 600 bbc no matter 1-153mm turbo or twin 88mm turbos.
Beautiful engines, the one to full your horsepower needs and more. Is it possible to do a B screw blown setup of SMX? God Bless you Steve and your team, keep up the good work. Hello from Finland.
Another successful Dyno pull 🤔 Folks when you know what you're doing this itsh looks so easy 🤚🙄but but but 👉if it was so easy everybody would be doing it🤷♂️
Steve, keep up the awesome job you have been doing with this engine design. It is very obvious that the things your doing with it, work. For anyone that doubts what these engines will do, keep in mind that Steve's engines break records. Not too many years ago if someone mentioned ProMod and endurance in the same sentence, well, people would have chuckled a bit. Steve and his crew have made that a reality. High horsepower, street able hp, dependable hp. From a team that continues to break boundaries set by the doubters, with innovation, and with clients that know his products are the best.
How do you monitor the hot side of the turbo? Do you even watch it after the motor is finished an off the dyno? Seeing how all the old turbo cars would glow bright red hot, I began to wonder how the high temps wouldn't melt the aluminum parts.
With the intercoolers sticking out so far, wouldn't that interfere with the car chassis? For instance, if this engine is in the front, would the intercoolers be sticking out near the wheel well?
Could you run a 2nd stage of injectors that kick in later to satisfy the fueling but at a lower pressure? Where is the sweet spot for the fuel pump in terms of GPH? What is the boost pressure drop across the intercoolers?
Hey Steve, have you been watching any of the banks killing a duramax or the monster truck engine series? I feel that that data monster logger thing he's pimping could possibly help to safely increase your already overly impressive hp and torque #s a shit ton. Just a thought.
What is it about a 481x/ SMX that makes it make more power per cubic inch than a conventional block.? Or is it all about the intake and cylinder head difference?
Here is a little something to think about. My buddy has a conventional headed bbc f3-140 and it just did 4k rwhp. This 481x at 4k will make less rwhp than that bbc.
@@funfun8095 that is a Brodix block and RFD heads. I just bought the little brother to it off him. It is a efi 540, RFD 24 Victor Pro heads, RFD 2897 port matched, f3-136, and made 3500 rwhp on the hub dyno Scott Duggins built bolt engines.
@@mirsakalash6667 yes sir! That is why 9 out of 10 Ford's you look at when at the track have switched over to Chevy power weather it's a bbc, sbc, or ls.
Jason Ritter I really like mopar, it represents pure muscle cars but I also really like Chevrolet the king of pony cars and they make powerful engines for me. They are more powerful than Ford.
@@mirsakalash6667 yeah if you ask me Chevy represents pure muscle but that is why they have a variety of builders, cubic inches, and brands, and everyone is happy. I will agree ford is the worst. Here is a funny about what Ford means Fucked Over Rebuilt Dodge lol
I'd like to know how you are able to measure this much power on a Stuska that's rated for 1600 h.p. If we are making 1500 ours can't hardly hold that back even. We are also using a swimming pool for our water reservoir. I call bullshit on this #. You all making comments don't realize what it takes to make an honest AND reliable 1000 h.p., let alone these #'s. Anyone who has done this, know's exactly what I am talking about. This guy reminds me of Nelson racing engines and his astronomical dyno #'s. Remember kiddies, you can make a dyno say anything you want. All you have to do is modify the friction factor or a host of any other parameters. I would stand totally corrected if you posted ALL of your #'s not just what we see on the screen here. Way more to setting up a dyno and have it be correct, than what you are seeing here. IF anyone here wants to talk trash, talk to me after you have put out a reliable 1k engine. You will be standing right beside me asking the same questions. Also, holly efi is a f-ing joke. Emtron, motec, ect, are professional ecu's. No professional would use a holly. You might as well just use a carburetor or a mefi. You all engine builders, know what I am talking about.....Just none of them ever comment. They just laugh and say to themselves "yeah right"
