wow this thread needs to be locked
Yeah, I haven't been the most clear. Just off idle is what I meant.
Hang a guage. Read a link. Until then, quit being a prick.
Hey, I gotta be me. Your discriptions about this issue have lead to some of the miss information in this thread. You are just now starting to explain yourself only after being questioned. I accept that ported vacumm goes down in the upper reaches of the rpms. But, I say again that ported vac increases up to a certain point and that point or points under that rpm range is where the majority of us do our driving. So, ported vacumm is benificial to fuel economy and performance.
Why? We are learning everything we never wanted to know about vacumm.
I posted this on the first page of the thread:
""""Actually, vacuum advance is pretty high at freeway cruising, as is vacuum. When you mash the throttle, timing retards a little cuz vacuum drops. Prevents detonation during higher cylinder pressures of WOT driving. Think of vacuum advance as fine economy tuning for mechanical advance. Vacuum allows more advance during light throttle cruising, which improves economy. When you mash it, it goes away. In the days of just mechanical, it would just run a little more retarded all the time.
It's a fairly fine tuned system, and anytime you make any engine mods, you alter it's effectiveness. That's why so many people with heavily modified engines just go to straight mechanical. Economy is less of a concern and it's hard to make mechanical and vacuum advance work perfectly together on your own.""""
While I occasionally stumble on my descriptions, I don't think it gets much clearer than that. Off throttle and off idle are commonly used terms that mean the same thing in the trade. The rpm that vacuum declines on ported turned out to be a little higher than I thought, after I hung a guage to look. At least I hung a guage, which is almost as difficult as clicking on many of the links provided.
I never questioned the benefits of vacuum advance, I just questioned that ported vacuum increases across the entire rpm range. I have no idea where you got that idea that I questioned the benefits of vacuum advance through a ported source.
That is counter to how vacuum advance is designed. To have it continue to increase over an the entire rpm range would result in far too much advance during high cylinder pressure situations, like WOT or high rpms, which would lead to engine damaging detonation.
I have tried to be civil through this discussion. I would appreciate the same consideration.
Civil???? Sooooooooooo, you didn't mean the prick thing? Cool.
That's all you got to say? LOL!
As you say, it was just you being you.
Carefull, or I'll come over there. What do you want? I don't accept that you were being civil, I think YOU were and still are being a prick. I confused you and bull99999999999999999999 earlier, but I make no mistake now.
I give up.
Your never gonna win against him, i learned that a long time ago
It's not about winning. We're done. Give it a rest.
LOL, so it's not just me, huh?
Come on You know you like to do it
No, most old timers on here have had to suck it up when faced with newbs and the like. It comes with the turf. We usually either resolve the issues or just decide to give it a rest. Fortunately, I have a good relationship with Stangers in the know.
Yea I suppose. When my "buttons" get pushed, I feel the need to "reset" them.
Sorry, I bought my first Mustang 26 years ago. Hard to think of myself as a noob.
Good that the Stangers in the know love you.
Yea, "All we need is love..........." It is spelled ........."newb" Think of it this way, I am spreading the love by helping you increase your post count.
It's spelled either way you cretin!
See, I cun speel C-R-E-T-I-N!!!!
Maybe someday I can reach the 6000 post mountain top and experience euphoria! Post count is what it is all about baby!!
