87 t
street and strip car.
stock unopened block and heads with exception of new valve springs.
ported throttebody, rjc pp, ls1 maf, stretched ic, 60 lb'rs, 62bb turbo, th dp, hooker style exhaust.
using two tt chips. one for 93 octane and 18psi, another for 116 and 24psi.
the car does not have alky.
I had put autolight 23s in it a couple years ago at the same time we did all mods. went to track to get a base tune but only made two passes before the stock trans started goofing up. I had put a differant tc in it, but it was used and I can't even remember what it was.
we made 2 high 11 second passes with the stock posi spinning one wheel.
trans, new ptc tq, and posi have been fixed, will tune the car this spring. the car has mostly sat inside last couple years and won't start. I'm going through the no start checklist printed from the vortex site, and I got as far as checking for the voltage pulse on the fi harness with a test light, before I had to get going the other day.
I pulled the plugs for a quick look and their black and very fouled looking. I was going to clean and reinstall, but thought Id see if anybody had a differant plug suggestion while their out

Why not regular old R43TS @ .035? Back to basics..
-
some people have pros and cons opinion on lots of plugs vs the combo and gas used.
I want to see if some prefer something over the delco 43s
-
I have never found any real difference between brands other than some offer more heat ranges for a given engine than others.
I have normally used Autolite 24s or 23s because I thought they were built better... I read they are now made in china so I guess it is luck of the draw. Actually, the last few times, I bought the Autolite racing plug which was an R 23 but I don't see any improvement, or difference.
Some like the NGK plugs and I have used them without a problem. They are more a generic one size fits all tho.
I don't like Champions from experiences from the old days with lousy quality control
-
To add on what Steve said buy from a real parts store or order from Sparkplug.com. I seen Autolite 23's from Advance auto that had electrode's vary .030 in length in the same box. Same horror stories will all brands. Counterfeit plugs are common in big box stores.

I pound the crap outta AC Delco 43`s.

i am actually changing mines today.
And since you guys are talking about plugs i have a set of CR43ts. Are these ok to use?

Yes, been my favorite plug for years. Buy them at Calvins and not Advance/Autozone.

Same here

I have good luck with both tight and loose gaps. if I had my choice though.... :tongue
-
should I just put a differant brand plug in each cylinder and see which cylinder makes the most power? :chin: :rofl:
I'm gonna go with the auto lite 23s one more time to compare then against the ngks when the car has a finished tune
thanks!

if both sets of plugs are good, you will not be able to tell one from the other

We weren't talking about your love life Mark. :rolleyes; :rofl:

i dropped in a set of ACDelco Cr43ts gaped at 28.

Gap them at 32. It will run and idle better. Unless your running ultra high boost and having spark blowout issues.

I guess that again coincides with your first response, lol!
I was listening, it just takes a while sometimes for my tiny brain to get to thinking clearly. :icon_eyes:
Uly, should I do the same gap with these auto lites?
-
0.035" will work fine
-

No blow out issues
boost was set at 24-26 Psi
now i have it at 21psi
as you say 32 plug gap coming soon.
thanks guys.
