Highest HP 4g63 engine (from 2007)
coastdown losses only measures static property; not dynamic.....when the engine is going FOT; thousands of factors jump into the equation and as the engine increases the power output; well so does the total lost of HP while the total percentage SHOULD decrease. Increase friction between all these metal components due to load is paramount in this equation....equal force is met with equal resistance "Third law: The mutual forces of action and reaction between two bodies are equal, opposite and collinear."
maybe 15-18% loss in Spyro's set up is closer to reality?
what's the highest confirm DJ WHP for an evo? Has it reached 1200WHP?

WHP is not a measure of the most powerful engine. If you fit ceramic bearings, superfinish all the drivetrain, fit lighter wheels, all this will make a big difference on a dynojet inertia test. So power to wheels increases because you lowered friction and inertial losses but engine is still making same horsepower. But now your estimated flywheel figure has increased by a greater factor again. More random numbers
I noticed he ignored to answer the cooling set-up but more importantly, what material he is using for the gears, pump, clutch and on and on......so who knows? We do know he is using a very light rotating assembly so I assume the same care goes to his drive-train parts which bring us to an efficient set-up thus decrease parasitic losses.
Yes maybe 5% is closer, maybe 45% is closer, maybe he rides a unicorn not a horse.

In all seriousness, I love this thread, been following it for some time now.
I take the numbers spouted with a pinch of salt, but marvel at the quality of the parts being produced. I very much like the idea of, if we can't buy what we want to make something perfect, lets MAKE IT.
Many many things we now take for granted, have been born through the same bloody minded attitude to succeed and I wish you all the luck in the world Spyros !
Lol! The super huge injectors idk who makes those, but he commonly uses ID injectors, also look up the ET US build, will most likely be done at the end of this year..

Hi
Just some quick posts of our new billet wrc/Lm intake manifolds.
The most advanced intake manifold system.
Next post how we design - built them - test them.
From our new Gas - Liquid-Loading-Field-Data Analysis and Multiphase-Flow Modeling software to flowbench to dyno to reality.
