Spark Plug Question..

[nmskull66]

Firebird 2012 Season Build and Results

When i first installed the kit on my car i changed the plugs to Autolite 103's. Theyve been in there this whole season but i was talking to my buddy nick(NV SS/School Boy) and he said when you have a boosted car and a nitrous car the nitrous car should have colder plugs than a boosted one. So this brings me to my question.. Is there any colder plugs for a 3800 out there than a AL103? or is that the one that everyone uses. Im getting some knock and im running 110 to help get rid of it as much as possible but theres only so much you can do without tuning the car, which id rather not due considering the last track day will be this friday at RSD. So if anyone knows anything that would be awesome!

So your running 110, and NOS without a tune and want colder plugs to take care of KR?

Did you check the plugs yet, 103s have a tendency to foul if daily driven for more than 5k miles.

The coldest possible plugs (readily avalible) to run in a 3800 are the tr8 race plugs ZZp sells... Good luck not fouling those on a stockish car driving in cool or cold weather.

103s should be fine, that's what I run

if you have no way of tuning id be running a wet shot over a dry setup.

next time shutoff your car at the top end and check all the plugs on the side of the return road or tow it back to the pits so you can read em...prob at least one of em showing signs of overheating

I've sprayed up to a 125 wet shot. I run BR7EF's, and have put 10k miles on the car since July. So, yes, you can run a cold plug and daily drive it.

But, you really should tune it.

not worth tuning it because durring winter im doing a motor swap

 

[GTPpower]

I'm not sure why you're worried about knock then.

He has to daily drive the car until it's time to swap the motor. He's saying the last time the car will be sprayed will be the final RSD, this weekend. Would rather not tune the car for one evening of racing.

How many bottles have you been through on those plugs? I would be changing them before every track outing or street race extravaganza.

I'm not sure that I would agree with spraying an untuned car if it's his daily driver.

 

[nmskull66]

i havent changed them since the cars been sprayed.. so im saying like 6-7 bottles

 

[Outlaw]

I'm not sure that I would agree with spraying an untuned car if it's his daily driver.

Nor would I, I'm just explaining it from his point of view

 

[1quick]

Is it a wet kit? People spray wet shots on untuned cars all the time

 

[nmskull66]

This car is a freak. bone stock motor and it handles nitrous without an issue. Everyone makes fun of me but this is why i love 3800's.

 

[nmskull66]

its a dry kit after the maf

 

[The Broken Regal]

I'm running nothing special... just some copper AL103s

you are running 110, 103s and supporting mods and are getting KR? haven't touched the tune ever? that is impressive to say the least

Im not going to lie, let alone killing the kr, you would greatly increase the life of your motor, get better gas mileage, and would probably pick up a few tenths on ET and trap higher with a tune

more like, because 3800.

Just curious how much your spraying and what kind of times you cut?

 

[PANDA]

Pull the plugs and see how they look.

Bro Herr runs no times so he can straight hustle..... 3800s will survive a low/medium spray 99 times out of a 100, many, many people do it.


Just run it how it is boy racer.

 

[Turbocharged400sbc]

its still dancing with the devil to spray something thats untuned or even setup for spray

I would throw another set of 103's at her. They're cheap as hell. Then put some 606's in her for the rest of its daily use. Would run better.

no tune what so ever. Cant get a tune even if i wanted to because A. ALL of my o2 sensors dont work because i run 110. B. I had a nitrous backfire along time ago (accidentally hit the button while the car was idling) so i have an intake leak somewhere, and C. I dont have hp tuners nor have anyone who really knows what there doing to do it. Id rather not say my times/what im spraying until after friday. Last time the car will be raced.

All this and your worried about colder spark plugs :rollpicard:

 

[RICH17]

Just drive the motor into the ground then. Buy a DD now tho

 

[DanJ]

I'm guessing 125+
