Intake manifolds under boost: when the air is two or three times more dense and also hotter, pressure pulses travel through it faster. This should make a 3000 rpm runner work at lower rpm. In practice, Richard's tests with the LS3 intake have shown otherwise. It's one of those things, like piston speed and pin offset. My opinion is that a 3000 rpm runner will work at 6000 rpm at sea level, thanks to standing waves, so with double the density, it should have VE peaks at 1500, 3000, 4500, 6000, and 7500 rpm.
@@TwoLotus2 you're right that speed increases with temperature. That is purely because of density decrease. I was mistaken; it's slower in denser air, not faster, so an impractically short runner might start to improve VE lower and lower in the rev range as boost is added.
Hope you see this.... The Belt is the problem??? I had a similar issue a couple months ago with belt slip under load. I checked everything, tension, contact amount, tensioner, etc. It couldn't be the belt, it was new..... LOL eventually, last thing, I changed the belt, problem solved! Ended up the grooves in the "original new" belt were too deep. It let the belt slip under load. I should have known better and checked the easiest thing 1st!
If it was belt or pulley slippage you probably wouldn't have gotten the exact same powercurve the second time you ran it. On top of that, the drop-offs in the torque curve correspond with peaks in boost pressure, which indicates back-pressure. When you run it again and don't find the problem, bolt on some stock headers on and see if it gets worse or not.
Hello first timer here .hi from Mexico I have been following you since199?? magazine's where we knew what's new .I mean boost. My uncle was subscribe to a mustang magazine and you have a article on that magazine. Well tnx for let us know and hear us ... saludos no habla mucho ingles
@@richardholdener1727 it was given to me and I was told it will support 800 on a 4.6 cobra motor. I was just seeing if I was told correctly. Thanks for everything you do and I have been a fan for years lol. I have more than a few of your books
He'd get a lot more views and bigger audience if he'd show these builds instead of brag about them, probably don't last long enough running roller lifters from comp..garbage
Confidence, not arrogance. Humility goes a long way.
Free plug for Pepsi. Will never drink Coke again.
OMG why you just start the turkey ain t so we can hear it you talk too much
@@anthonymarcotte9049 huh? I don't have a turkey. I think you posted in the wrong place. You been drinkin?

Well, if its the speed of sound in air that you are talking about, it is only dependent on air temperature, not density.

But the thing is, if it were the belt, the boost would drop. He said boost wasn’t dropping.

Welcome back!
hey would you be able to do an ebay intercooler shoot out?
This has probably already been figured out , I realize I'm late to the party , could it be the blower and or intercooler is hurt ?
I think the 6.0 problem is the spring pressure on the seat is too light. Shim the springs.
Is that intercooler from Motion Raceworks single-pass or three-pass?
That engine is beautiful
Question a 70mm turbo with a .96 hot side and what is the max hp output. Will it work on a Ford coyote and it navigator motor
i need more info on the turbo-how much power do you want

😮
How do you pick the size for a twin set up? Do you just do the math for one turbo and cut that in half?
size the turbos for the desired power level
What's more impressive the pizza or the engine??? What twin turbo engine😳🍕🍕🍕🎉
Nice combo
eBay intercooler vs pro charger, Mishi Moto ,on3 Four instance A good price something from $1000-$100 eBay

I wish you stop talking and let us see it running so he does is talk talk talk never shows nothing Harley
