Wtf, the one spark plug I been checking wasnt too bad, so I said hell with it, Ill put the old autolites back in, 10 mins later...... VROOOOOM!!!! I think I should get some new plugs.

 

what kind of plugs were they??? they werent NGK tr55's were they???? Have had some problems with them before...

 

have the plug wires wrong?

 

NGK TR6s, I've also had the pleasure of finding out with my alternator, PS, AC, and heater core delete I can change 6 of the plugs with a plug socket and 3/4 wrench to go on the socket, in just about 10 minutes, the last two, 6 and 8 add about another 10 on top of that though lol....... back to what works, a new set of $1.80 ea. Autolite 106s....

Went to the track tonight to run it and got "rained out" due to excessive fog..
Friday night Ill post times with the new cam, one thing I noticed that was wierd was when I set my fuel pressure, the pressure goes UP with vaccume line attatched?! isnt that backwards? is it something the Aeromotive afpr does? I set my no vacuume pressure to 43, running its about 55psi on stock 24lb injectors...... hopefully that will be enough fuel to feed the beast..even if it takes 100% duty cycle, if not ill jack it up some more, but Im scared to go too high now as I learned too much pressure will lock up the injector.

 

i can vouche for it being up and runnning

edit- hit me up if u think we can do those subframes tomorrow, otherwise i'm probably headed back to college station. i would wanna all the new goodies as well but there's a few things i wanna take the time to do while i have it apart.

 

if you go out there on Friday (HRP) let me know, we could cruise up there, or meet up....

 

Ill be out there on friday for sure, wednesday night was a bummer! lol

Im so eager to see what the new setup does, I think properly tuned an 11.1-11.2 is in order, but its not tuned good yet lol. Im too scared to use the N20 to go for those magical 9s I wanted after my unpleasant scare.

 

I don't get the internet crowd's fatuation with NGK spark plugs. What is it? I have had to replace a trememdous of those things just to get a car to stop missing so I could tune it. AC, Autolite, Champion, all are good plugs. I see guys pulling new plugs out of a new vehicle, and put NGKs in it. Guys need to realize, if a Chevy is not missing, different plugs will not run one bit faster. I can't really say about Ford, MOPAR or motorcyles or the ricers, but Chevy engines don't care. Any gains with some trick spark plug, if the car was not missing, are simply imagined. I used to keep a box or removed/misfiring NGKs here next to the dyno PC to show guys, but finally threw it away. The TR6 seem to give the most grief. I use Autolite here. I'll probably hear about this one, flame away.

one question mr. ed wright..... what does "fatuation" mean.... looked it up in web and got 0 results back. did you mean "infatuation-A foolish, unreasoning, or extravagant passion or attraction".... not trying to be a smart-*** just wanting to learn something new everyday....

I have had a similar problem with the NGK's before, and i just replaced the plug that was fouled (cracked), with a new one; next time that i do plugs, wires, etc i will be using a different spark plug brand....

 

Well I guess you should tell this to the guys at GMHTP, b/c this month in their Quick Test Article they dynoed an LS1 with NGK TR55's and it got 324.9 RWHP & 328.1 RWTQ with the first set of plugs. After switching to the plug they were testing the Brisk Premium LGS spark plugs they dynoed again and got 328.2 RWHP & 328.5 RWTQ. A gain of 3.3 horses and .4RWTQ.... not bad for a set of $12-$20 plugs..... At the end of the article GMHTP always says if they recommend them or not, in this instance they said

 

I just put them in cause everyone said ohh NGK TR6 thats THE plug to use nitrous on...apparently its not the plug to run gasoline on! lol Whatever im sold on my autolites now

Firebird 07 Ill be at the big HRP tommorrow, just look for a muave (purple ) 94 Z28 with big ol' 30 x 9 Hoosier radials out back, salad shooters in the front

 

Ed, I have a slight miss in my car right now and I'm running NGK's about 6 months old, think that could be my prob? It's got new plug wires and I pulled each wire off one at a time to see if it was one certain cylinder misfiring, it aint. It does seem to be on the driver's side only though and that's the side that's running a little bit lean according to datamaster, I figured with a misfire it would run rich on that side, is that wrong thinking? Ever heard of an opti causing a misfire on just one side? I really dont wanna change the opti unless I know that's the problem. What autolites do ya recommend?

Got me there.

 

3.3 hp is such a small a difference, many LS1 cars will often pick up that much from simply the oil warming up. The only way most experienced dyno operators would accept results like that would be to do a-b-a testing. That entails averaging three or four pulls with the original plugs, to make certain it is repeating, averaging three or four with the new plugs, then putting the old plugs back in and making more pulls to average, to make certain it looses whatever you saw as a gain. Averaging dyno pulls both ways, before and after a small change, then you have accurate results. A 10 or 15 hp gain or loss is one thing, 3.3 is another. Takes more time to know for certain, otherwise you can end up chasing your tail over what could really be a small loss. John Lingenfelter convinced me of that concept ever 20 years ago.

I wouldn't run out and buy spark plugs due to a test I saw in a magazine.

To the other gentleman, I use 104 Autolites in mine. For normally aspirated & stock compression ratio, just tell the parts man you want the recomended platinum Autolite plug for your car. Factory AC plugs are fine also. I just find the Autolite plugs more durable in a blown application, and easier to read at the track in anything.

Take care, Ed
