28* initial timing for a 318? How can that be?
I see all the usual suspects have chimed in with their nonsense. Thank you to those who went against the onslaught & were brave enough to say MVA [ or locked timing ] worked for me. The saddest part of this thread is that I thought I had a friend amongst the posters. His comments show what a back-stabber he is.
Now for some facts [ listening TT.5? ]:
- I never tried to hide anything about the original build; using a cam with 20* less duration can be seen in the link in post#1. The reason I did not post the whole story was that the print would be too small to read, so I just provided the important info so that it made sense.
- I too would have suggested a smaller cam if I was advising the chap, but some people, for various reasons, want to stick with what they have & tune it as best they can. [ In this case I will disagree with Steve & say it needs a LOT more than 28* for best idle ]
- yes, I constantly, recommend MVA because it works. There are times when it will not work such as when the idle vac is too low; then, locked timing is an option.
- the nonsense/lies from Newbomb Turk about not publishing my own results. I have done it many times. But who am I, nobody has heard of me in the USA? Why should we believe you? He must think I am as stupid as he is... That is why I provide links to that of other people, much smarter than some on this forum, who have been using MVA & getting nicer running engines.
- it shows how little some know when, because of their own ignorance in trying to discredit MVA benefits, claim the rest of the ign curve will be compromised. I have done more MVA tuning than Turk has had hot dinners. I have three booked in at the moment, all different brands.
-lastly, for those who want learn about MVA benefits. Nick, Mopar man of Nicks Garage, did a dyno tune about 2 weeks back on a 455 Buick. At about 18 min in, he connects up MVA with the engine idling & you can hear the idle smooth out & increase about 200 rpm. He then talks about MVA for a minute or two. Maybe somebody could link the video? The idle got smoother because more of the mixture got burned at the right time & made more HP, which is why rpm increased.
- MVA works on all brands when suitable. Logo on the valve cover doesn't matter.
