 Subject: did i gap my autolites right??
IP: Logged
Message:
I just changed my bosch platinums out today for some 3923s and i decided to set the gap at .045
my label calls for .040
(I have a 98 rc v6 at 51k miles) with accell 300+ wires and an accell coil among other things (180 tstat stupid jet chip stage 2 etc) it seems to run fine, I just wnated to know if theres a durability issue with the overgap.
thanks for your input

no that will be fine, you may even be able to open
them to .050 with the hotter coil.
Are they reg 3923 or the AP's
put a few hundred miles on them than pull a plug
and see how they look, should be a tan color

thanks larry they are the regular copper core cheap 3923s i have driven it to and from work today and it dosent seem as dogish as it did under light throttle.
i will take them out at my next oil change (in 400 miles) to check them and make sure there not to hot. also sometimes i idle alot almost every day (about 45 mins total breaks and lunch) and every 10 mins i rev it up to 1,000 for 30 seconds. is that ok or should i stop the idleing altogether?
once again thanks

question, why did you buy those cheap as hell autolites? you don't have to gap the bosch plugs, and they seem to last longer. Another question, what temp thermostat does your truck specify? because it is stupid to run a colder thermostat than what the manual calls for because your truck doesn't run as good if it is opening earlier allowing the engine to be colder. there is nothing that says doing that will get you any more power.

FACT
Mopar Tech Articles say the V6 will produce more
power running in the 182 to 187 temp range the 195
was installed for better emissions.
FACT
A cooler engine is more volumetricly efficient
The idleing will not hurt it as long as it is also
driven every day.
With the reg plugs and a hot coil you can go upto
.050 but see how they look before you open the gap
1 heat range on a plug will change cyl temps aprox
170 degrees, you can also raise and lower cyl
temps by about 70 degrees by changing the gap.
On any high performance or any engine for that
matter it is worth the time it takes to play with
diff heat ranges and gaps to get to an optimal
burn temp were the plugs are tan.
This comes from 30 years buiding engines, the same
2 engines built identical are never exactly the
same and you need to do this to get a great
running motor.
The motors I build and my reputation for an
excellent running motor does not come from pre
gaped plugs that I just drop in the motors, I
personaly tweak every motor that leaves our shop

nyeah i have a 180 tstat and it runs alot better in the summer (it ran like a dog with its tongue sticking out at 195) yeah its driven 24 miles round trip everyday to and from work and any other errands i run.
also chris the colder we make our magnum engines the less likely they are to ping. dc in all of its infinate wisdom didnt put nock sensors on the magnums and all the computer can do is advance the he** out of the spark causing detonation it has no way of retarding the spark.

yeah, in some places though, it is against the law to do that especially in california because of emmisions. a cold engine doesn't allow the system to get into a closed loop, so the emission controls will not work, in turn burning more fuel because it never gets warm to set the controls.

The mopar computers no these trucks will go into
closed loop around 120 130 degrees but the comp
is looking for at least 170 or it will throw
a code running to cold that is for emissions and
for the cat to ignite and operate.
a 180 thermo will run around a 185 engine temp and
still pass any emissions test

yeah i was going to go for a 160 stat but i thought it would give me a code (and it would be too cold in the winter my 180 t-stat takes long enough)i live in ohio and in my county we dont have emissions tests so that wouldnt bother me anyways but its always nice to be lega lol ;-)it does really run a little better in the summer with the ac on (i dont tow anything but i follow the heavy duty schedule because i run the crap out of my dak) i think it may be a disease trompus alotus LOL
thanks for all of your input everyone
