If you get power from advancing timing, it means that before you did it you were wasting power which was allready there available to you.
If you go around saying to people that advancing timing gives power, less knowledgable people will just go an advance their heart away, not really knowing what it does.
so you sometimes increase timing to increase power?
Did you even read my post?Quote:

You know what saxman and I are saying, no need to be a smartass and pick apart what we are saying, the argument is closed.
oh, i think you are wrong.
my personal belief is that increasing timing DOES increase power.
particulary if people follow my directions to do it. (post #8)
i.e. to 18' - the outer mark on the crank pulley and WITHIN Honda's original specifications of:
16' BTDC +/- 2'
AND runing 98 octane.
so, under what circumstances will this NOT increase power?
Ok, you clearly did not understand what I was saying.
I am talking about timing on an individual power stroke level, not a whole rpm range global scale.
In your specific example, I wouldn't be suprised if you LOSE power.
It takes far longer to burn 98octane fuels than 91/93 which is recommended by the manual. 2 degrees may not make that up.
Advancing timing over the whole rev-range is stupid. How do you know that Honda didn't go to MBTT (max best torque timing) at some points in the rev-range? By advancing you are going past this, straight into knock teritory. You may benefit out in some areas (due to Honda's conservative standard timing maps) but you can never be sure.
Advancing to 18 degrees is a waste of time.
On my previous engine, I ran at 21.5degrees base timing on 95 octane. No audible knock count. The butt dyno didn't indicate any increase in power at multiple intervals between stock and this level.
So to answer your question. If your comparing running 93 octane at 16degrees to 98 octane at 18degrees, then i'm going to claim that you will not make any more peak power at all, maybe less.

BNTW2 - we also dont have 93 octane here, where are you posting from, lol!
(i am going to laugh my ass off if you have been thinking that the '98 octane' that i refered to is the same as usa 98 octane!)
I am talking about RON. I am assuming that the 98 RON you are talking about is BP Ultimate or Optimax or whatever.
95 RON I am talking about normal Premium.
I don't know or care what RON normal fuel is. I said 91/93 because thats what I assumed it is.
If we don't have 93 RON here, what the hell is normal?
