debating on reducing gap

[slowion2]

I figure Sam and/or Jay will jump on this unless one of the others in my head who would know sees it first.

Somewhat recently I reduced my plug gap to .040 from the stock .045, and it got rid of some of the surging from the increased cyl pressure.

Now I'm debating on closing it again to .035 or so. It might be in my head, but I thought I still felt some this past weekend during that run with the Sentra. Maybe .038 first to see how it is? I'd rather not go lower than .035 unless it's really highly recommended. I know some Redline guys are running .030 gap now too with the same plugs (BKR7E).

[S.Bretz]

dropping to a .035 gap won't hurt anything.

[intimidator400]

I think either one of those would probably help you out, at least a little bit. I would try .035. I think that should be enough of a change in the plug gap to help you out without causing any problems. Like you said there are guys running redlines with a smaller gap without any problems.

[intimidator400]

I think that GM was playing it really safe with a stock gap of .045. I wouldn't recommend going lower than that unless you plan on going to the track to do some test and tuning.

I would drop it to .035 also.

I would drop it to .035 also.

yeah, I'm actually going to pull the plugs and drop it to that tonight or tomorrow, need to inspect Chris's plugs too since it's been in a week.

yeah vinny, with the gas i was running 35 on the gap, the best way is to bring it down, and then check em after you spray, but thats from an LLO point of view

[slowion2]

right, I think that's what you had mentioned before Dan

when I dropped it to .040 I did that and seemed alright, and supposedly there is one or two other Ions on spray running the same gap on these plugs (.035) and it's working out well.

some of these redline guys are down to .030 or .028 now [img]{SMILIES_PATH}/shock.gif[/img]

[nefarious]

yup, seriously, you are getting pretty jiggy with things, if you really want the most out of the gas, its time to dyno tune the jetting, with ignition retarding capabilities [img]{SMILIES_PATH}/icon_twisted.gif[/img]

bingo. Elvis is coming down to work on his turbo setup, and he's got a DIS2 we're going to try and install. if it works, I'll invest in one myself

I still need to get rid of that stock exhaust manifold, I know that thing is killing me.

I don't mind having mine set the way it is right now honestly, keep it as a quick daily, and build up something else on the side or for others.

I thoguht u had the dis2 [img]{SMILIES_PATH}/icon_question.gif[/img] I know late but what did u decide to do?

[slowion2]

I said I might look into it eventually, but I'm on stock timing with the 7E's right now.

brought my gap and Chris's gap down to .035 and all issues are fixed...

well, except wheelspin anyway.

I'm going to have to do that too macho when I spray?


and notecing how the miata's run stock 10degrees timing and do better (way betta) at 14 or above, what should I run it w/ the nitrous?

[TurboSL1]

I'm going to have to tune the fuck out of that bitch at the dyno

[slowion2]

if you're spraying on it, I"d see how it likes the 50 shot on stock timing, should be ok at 75 I think but don't quote me

you need to read knock and use colder plugs
