Going to Change the Gaps for a Direct Comparison - Page 3

^^ Are you serious

.... all the way back to Marcey.... what a stupid ass remark.

Hot rodders have known for DECADES that the larger the spark the better and more complete the burn. There isnt one magical gap since no two engine are the same... run the largest possible gap that your engine will allow without missing..... its that simple and theres no secret to it.

^^ He was referring to Focus owners, not in general.

Walter Marcy did do this test several years back and found that .060 was the ideal maximum gap for power on NA cars running light mods.

all i was posting up was just to let people know something about what I was doing, as every time i read a gap thread, i see the same question 'why can't someone just regap, instead of changing the plugs at the same time?' thought i would contribute and offer up something on my own, and just report back some info. i never claimed it was some perfect, end-all thing, just something that may be interesting to others. that is why i said it would be subjective. apparently we cannot post opinions on this site anymore either.

No Evan it was because I don't agree with why we are testing something that was found out YEARS ago for the Duratec and the theory's around gapping have been around for ages. I never said you can't post your opinions but the way you plan on doing the test will come to no conclusion and is very flawed so reporting an "accurate" analysis would come up with many variables that aren't controllable.

PS: You could've PM'd me "why" but no as usual, you like to cause drama just like in the past. And yes this is public because you decided to make it that way

Not sure there will be a difference from re-gapping the stockers.

Exactly, WHY are we doing something that was proved YEARS back on the duratec? Hell I think I have a link to that thread on the Jet somewhere in here. Also Marcy DYNO tested, not street tested, because as anyone testing anything knows, to get an ACCURATE test, you can't do it on the street because it will not be like variables every time. So anything done on the street will not have anything to fall back on.

The issue with opening the Autolite 104 plugs up to .060+ is they get too hot and the gaps get all wonky. There was a thread about gapping and a few people were having issues with the car running great for a week and then starting to run like ass. They checked their one week old plugs and some opened themselves to .070, some closed themselves to .050, etc.

I myself have had the same issue.

I stick with Autolite 104s gapped at the maximum stock gap (maybe a tiny bit more, i forget) and i don't have any issues. Great idle, great power, the gaps don't open themselves to crazy weird settings.

yes, see, that is what i have also seen...many have said that .060 was too big. FRPP said that I should go to .054, and that .060 would be too big. not sure if that applies to copper or not though, i did not ask. the book says max should be .053. i will try .054 first.

ken, i am not debating what anyone else has ever said. what i am saying is that there is a lot of disagreement over what is best. not even getting into temp ranges or material type. just looking at eliminating an extra variable of changing the plugs at the same time. that is all. not even trying to say one gap is better than the other. i only wanted to report what i see personally, from one gap to another on the same plug. there are no dynos around here. closest is about an hour each way, and i do not even know if they are good.

least you didnt infract me for expressing my opinion. that was good of you.

If I was a moderator I would infract you for being a troll.
There are too many variables for on the road testing.
Do you really think your ass dyno means anything at all.
You need to be at least doing data capture to even make a point with on the road testing.

i love this place.

arrestmespi · 11-07-2009, 03:19 PM

do you think you can actually get any results that are anywhere close to scientific?
Well do ya boy?

arrestmespi · 11-07-2009, 03:24 PM

I haven't posted in over 2 months on this forum but I saw this thread and how much fail was inside it so I have to speak up about the failness of this idea.

NAD23ZX3 · 11-07-2009, 05:13 PM

I'm still wondering what all those rep points are after the throttle body spacer/heat soak and now this

ehancock · 11-07-2009, 05:18 PM

For the record, I wasn't arguing the fact that gapping the plugs at .060 made power. It was documented on Marcy's dyno (graphs were posted even) and i know that he ran large gaps on all of his cars. I think the issues with plugs opening up in my experience was related to specific plugs, not ALL autolite 104 plugs. It only happened to a couple of my plugs in my history of running autolite 104s. Anyways, I checked and i'm running .056 with no issues. I made great power as shown in my dyno thread so i'm not worried about it.
