Aloha again guys,
I just want some help to figure out why my truck has
soo much power w/timing set at 18*btc as compared to 14*btc.The
reason I messed w/the timing, I read on a post a while back that someone had done this and he noted an improvement in MPG's.Being
that was my primary goal,I figured I'd try it.But lo and behold I got gobs
of power instead.I haven't figured out my new MPG's yet but I do know
that I burned 3/8 tank going back and forth between settings of 10*,14*, and 18* and road testing after each setting.Went from 14* to
18* numerous times w/same results--18*=smoking tires across intersec-
tion;14*=small chirp crossing same intersection.18*=wheel hop while
screaming tires ;14*=no wheelhop and small chirp crossing same.18*=
pinned back into seat torque while 14*=no pinned to seat torque.All the above was witnessed by my nephew who wants to try it on his ride
now.He knows I had raced cars(1/4 mile drags)for many years and thinks I did something more than just advanced timing.
Conanski, you seem to have answers for everything so I am
begging for your help. I can't afford to fix a broken motor right now
cause I'm in the process of demolishing my house and building a new
one in it's place. That's the main reason I bought this truck for and I
am not at ease about how I came about all this power.Can you or any
other FTE experts think of a LOGICAL reason why a 4* variation in
timing could generate such an increase in power.In answer to your reply in my previous post,all timing was done w/spout jumper out and
the only thing I did wrong was forgetting to plug it back in after timing
it to 18* once and that time the power was not that great.Lucky the
jumper was still sitting on the windshield washer reservoir when I got
back.Plugged it back in and road tested and you guessed it , pinned to
seat power again.I asked a couple of my friends for their opinions (2 of
which are pro. mechanics) and they said it was impossible.The rest of
the guys I asked said just enjoy the benefits I got ("don't look a gift
horse in the mouth") Whatever the f--k that means!
Any explanation would be greatly appreciated .Thank God I
had my nephew w/ me to verify my story.He explained in detail what I
did so not one of my buddies could accuse me of being on drugs again.
Actually,this truck is the reason I quit using drugs cause it's taken a lot
of my spare time and $$$ but I love it. My wife says it's My Salvation and we're never parting w/it.I kinda created my own monster when I
bought it but it has brought a lotta happiness to our home.Not only do
I have a big truck to haul stuff with,a hobby I kinda gave up on(racing),
my whole family can fit in it for camping,diving,surfing,fishing trips and
most importantly , I am now "drug free".thanks to this hunka metal.
Sorry Ole Betsy I meant this beautiful blue steed.
Conanski,what do you think of this 4* power additive?
Aloha from Maui,HI,

We asked you several questions on your other threads, you never answered them.

You have not verified that it is actually advanced 18*, you may just be making up for some other short coming someplace else. The 18* mark on the wheel may in fact only be 12*of advance, at 10* on the wheel it may be retarded 5* or more to start with. So you have to bump it way up to make up for it.

Until you check the items we had asked about in the other threads of yours there is no way of knowing whats going on.

Check the other stuff we asked about and also have you used a vacuum gauge to find out what it says about it?

Again, that 18* reading you get may be totally useless as to the true amount of advance with the timing light.

With your "racing past" you speak of yoiu should have no trouble finding out what is truly going on with it.

 

Thanks Danr1,
I guess I'll bring #1 piston to tdc,then check my timing mark

pointer to see if it's at 0*(tdc)and if it's not then more than likely the harmonic balancer parts have separated ,right? I've never heard of this
happening before but there's always the first time and I'll check it in the
morning.But irregardless of this,don't you think that 4* advance in timing
causing so much power variation is odd?Say I bring #1 piston to TDC and
my pointer points to 10*,when I start it and point my lite to,it should show
20*btc right? I just can't figure why advancing the timing 4* can do so
much powerwise.I've gone from 10* (where it was) , then 14*(little improvement),and 18*(holy ****) Then alternating between 14 and18* about 10 times w/same results- 14*=small power,18*=big power.All timing
was set w/spout out except I forgot to replace the spout connector once
w/timing at18* but power wasn't as great.No matter what,I'm still dealing
w/4*advance.If I'm missing something please educate me.

That's what it kinda looking like, its starting out retarded so bad that any little bit of advance helps if but when you push it way up its brings it into range so when the computer takes over from there it runs great.

Not so much 4* of difference, just that that 4* brings it closer to the 10 or 12* of base timing it needs to start with.

You may find the chain is tight and the damper hasn't spun on the rubber but if not you'd probably find the computer adds no timing advance over the base timing even with the spout in.

It could be one or a combination of all of those possible issues. Any of that is much more likely to be the reason for its going to 18* over you're having a "freak" motor.

Anyway you have several things to check, none of us can begin to answer the reason why until you fill in the blanks.

 

if you are "drug free" it is because you stopped doing drugs, not because of your truck.

 

You know, there is such a thing as replacing one habit with another... Not that this has anything to do with timing...

 

Motors make the most power on the edge of detonation. A better quality or higher octane fuel will allow more timing before detonation. There are a lot of factors to consider. I would just stop wondering why and be happy you found some "FREE" power.

I hang in the mustang world and know that every stang likes something a bit different than its sibling.
