im installing nitrous this week and will be pilled to 100 shot. Question is will my TR55 iridium plugs be ok (for short peroid) or do i need to switch to TR6s before i even think about spraying??

Depends on how rich it runs on the juice, and how long you press the button for. It's the heat build-up that kills plugs, so it all depends on case-by-case if they will work or not.
If it's a dry shot spraying very near the MAF then you'll be fine for a typical quarter-mile pass because it will be rich and pull timing on its own.
If for any reason you go lean for more than a couple of seconds then the plugs are history and may take out the motor too. Most people don't want to risk their motor because of a sparkplug.

The time & load factor counts a lot here. If you make a long pass or do a highway run up into overdrive on the bottle then your plugs aren't going to make it.
Some shorter 5-to-8 second blasts in lower gears would be just fine. It normally doesn't take more than a few seconds on the bottle to decide the race on the street anyway.

Thank you for your input. Its a wet Kit and I will be changing plugs to TR6s soon just wanted to put it on and go test it out with a few quick blast down the street. Ill be putting TR6s in before I do any racing, going to dyno and tune sometime this week, then go out hand some peeps their *** this weekend!!!
