Author Topic: NITROUS MINGRYGT ¯ Member # 2439 posted                              IM GETTING READY TO PUT AN NX WET KIT ON MY 02 GT THIS WEEKEND. I WAS TOLD THAT NITROUS SHOULDNT BE RUN WITH THE PLATINUM PLUGS THAT COME OE ON THE CAR. SO I OUT SOME COPPER CORED AND GAPPED IT AT .035 INSTEAD OF 0.55 THAT IT CALLS FOR. WELL NOW THE PERFORMANCE WAS DRAMATICALLY AFFECTED. SO MY QUESTION IS DO I HAVE TO RUN COPPER CORES OR CAN I RUN THE PLATINUMS THAT WERE IN THE CAR ORIGANALLY? IM LOOKING FOR LONGEVITY OF THE MOTOR. I GAPPED THE PLUGS DIFFERENTLY CAUSE SOMEONE THAT HAS THE SAME SETUP GAPPED THEM THAT WAY AND SAID I SHOULD DO THE SAME. ANY HELP WOULD BE APPRECIATED. THANKS -------------------- R.I.P.

Copper core plugs will not affect performance. If anything, its the gap. Go ahead and put htem back to .055, or in the middle at .045. The reason for closing the gap, is so that the nitrous doesnt blow out the flame. With a small 150 shot, you wont be running enough cylinder pressure to have to worry about it. You usually have to start closing the gap when you run numbers around 300hp+ -------------------- [img]http://www.zimmermanmotorsports.com/zimban2.gif[/img] Posts: 222 | From: Bay Area | Registered: Feb 2002  |  : MINGRYGT ¯ Member # 2439 posted                              SO THEN YOU THINK ITS THE GAP NOT THE CRAPPY AUTO LITE COPPER CORES THEMSELVES? -------------------- R.I.P. MIKE STARKEY 5-17-03 Posts: 488 | From: Concord | Registered: Feb 2003  |  : customN2O ¯ Member # 914 posted                                 Yes, the only thing a plug does is spark. The platinum plugs use a very thin and small electode, with a platinum tip. This will get burned up by the nitrous, and it doesnt produce a very big spark. The copper core plugs will give you a much bigger spark, and wont corrode like the platinum with nitrous use. Try setting the gap to .045, and see how it runs. Thats what I run in my 12:1 350, spraying 300hp of nitrous, with no problems. .035 is just way too small. I would even try the .055 you were using, and see if you run into any problems with the nitrous. I doubt you will. -------------------- [img]http://www.zimmermanmotorsports.com/zimban2.gif[/img] Posts: 222 | From: Bay Area | Registered: Feb 2002  |  : MINGRYGT ¯ Member # 2439 posted                              ALRIGHT IM GONNA PULL THEM AND RE GAP THEM.
