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.

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.

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.

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?

When you are using high boost, what amount of overlap does the camshaft have. Does to much overlap cause reversion.

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.
