NONE OF YOU are using actual calibrated measurements from an actual lister, you are taking someone else's numbers for max injection pump delivery and sticking that in as gospel for fuel consumption, NOBODY has put a flowmeter on the intake but you're talking about volumetric efficiency, NOBODY has metered pre-analysed fuel and total thermal rejection but you're talking about thermal efficiency.
My bet is more than one of you are playing with poxy computer simulation software, which is closed source anayway and you haven't analysed the code, you are typing in made up numbers as though they were gospel, and treating the results as though Moses himself handed them to you on tablets of stone.
Until someone can post photographs of their engine test lab, which even a DIY version of would cost at least 25 thousand bucks, and the same again to calibrate everything, then quite frankly you're all talking bollocks, which I don't have an issue with, unless it is presented as scientific fact, which it is being.
Where the bloody hell does kyrdawg get 30.83 BHP @ 100% Thermal efficiency for a 6/1 if not from out of his ass.
Sorry to be blunt, but there is no other way of saying it, you never saw those numbers or anything approaching them from a 6/1
Volumetric efficiency of a 6/1 will be very high, approaching parity at least, themal efficiency is also very high, approaching 50%, I mean, HE_LLOOOOO, everyone else is talking about their 6/1 running too cold to heat the oil, too cold for WVO, to cold to just plumb a calorifier into the coolant circuit to get all the hit water you could want....
Does anyone do any actual calculation with real numbers, and not stuff they just pulled out of their ass?
I did a spreadsheet MANY years agp so people could calculate engine and prop etc for their boats, one of the very FIRST things it tell you is that althout it only requires a few numbers to set it going, you CANNOT GUESS AT ANY OF THEM, you must KNOW FOR A FACT, else you cannot use the spreadsheet at all.
Here is a scenario, ask Mr Belk
Rifle chambered for 30.06, 24 inch barrel with 7 lands and 6 degree twist, you are stood 150 yards down rang in front of it.
now you lot, you will guess at weight of propellant, guess at type of propellant, guess at weight of bullet, guess at type of bullet, guess at weather conditions, guess at any intervening foliage, guess at what clothing or armour the "target" is wearing, and come out and say the bullet will nail that sucker right between the eyes, all we have to do is blah blah blah and lube the barrel with teflon and lower the modulus of elasticity of air and do it on mars where gravity is lower and make the bullet out of unobtanium and so on.
Mr Belk, who knows what he is talking about, will realise the rifle has no firing pin, no sights anyway, no receiver, no sear pin, kneel down, pick up a rock, put rock in catapult and hit the target dead on.
Meanwhile, back in the real world, some of you should try actually buying, owning, and using a lister for a few thousand hours, before telling everyone else what improvements can be made.
grrrrr.... lol
can I have my grumpy old man award now please....
