Well, just sitting here wondering what to do with myself ... so I thought I would see if I could arouse some moe conversation among the list.. The question of the week is: Why does the torque of an e
Sure glad you found that in the rule book, now I can unload my timing stand gattling gun. Dave Dahlgren should be on shortly with your torque answer. Maybe even in English. LOL. Have a good day Mayf
volumetric efficiency is inverse to rpm after peak torque. most engines make peak hp 15% higher in rpm that peak torque. Look at some typical ve curves and it becomes self explanatory hp=(torque/5252
Awwww Dave, you didn't answer the question. I know what the formula for HP is. The question is why does the torque fall off. What is the engineering reason for it. Why /does /VE fall off? I've looked
We know that at minimum the resistance to port flow goes up at the square of port velocity . How turbulent does air/fuel become in a port at 300 f/s . Maybe that's why HP peaks when it does . Has any
My guess is that volumetric efficiency falls off as RPM rises; the cylinders just don't get filled with fuel/air. Regards, Neil Tucson, AZ --Original Message-- From: land-speed-bounces+neil=dbelltec
What would a vortex generator accomplish? Might just take energy out of the flow and have a negative effect on VE. There is always acoustic tuning (of the combined port and stack length) to provide a

Ford did the same thing to the 4.6 Motor in My Lincoln Mark VIII, you can really feel the difference when the engine switches from the long runners to the short runners. And they did that design back
Well, shoot. This did not generate as much discussion as I hoped it would. It is definitely not a subject I am familiar with so was looking forward to lots of interesting reasons why internal combust
Thanks for the reminder Mike--my first wife had a Mark VIII with the 4.6L DOHC engine. It seemed to rev a lot smoother and had higher HP per cubic inch than my 93 Corvette 5.7L Lance ________________
It's and inherent characteristic of valved IC engines--even with supercharging you still have the inertial effects of stopping and starting the flow in the ports. Even with infinitely variable valve

OK Mayf. I'm going to go back and dig out Obert's book (published when I was 5) and visit with him for a while. Sometime later -- This is hard to do in a short burst but I'll try...... At all speeds
Heck, I'M still trying to figure out what a enine is. LOL I think it's a flub by the left fielder ?...or what comes before eten ? I think it's that language movement that enjoyed popularity in the 30

Pinch your nose and say it like a three year old might say it, lol.. so I guess typing and spelling are now a requirement for the list, eh? Ok, I'll remember that.. mayf _____________________________
