Default Which plugs

I am looking at putting the jug on the car this week. With a 100 hp dry kit should i be using ngk tr5 or tr6 plugs? what is the most one should spray with a dry kit? one more thing, i was thinking of using my old nos dry kit from my mustang and only using one solenoid. If i decide to run only one line into the air box instead of two lines as the nos 5117 kit shows, should i be using a bigger jet to srpay 100hp given that it will only be spraying on one side of the air box.

I would use TR6's. I sprayed a 125 dry shot on my LS1 for a couple of years with no problems. You will have to run a bigger jet if using 1 to adjust for the difference. Best call NOS for the conversion info. I also would definately fun a RPM window switch, fuel pressure safety switch, WOT switch and redundant N2o solenoids for added safety

Enjoy!

I will have to look at my notes for the jet size, used the largest ones with the kit and then had them machined out a few 100ths out....all of this was done on 93 octane gas... I did have the MAF recalibrated to provide additional fuel when spraying....never made it to the dyno

I recommend TR6s gapped between .035 and .039.

I am currently running TR7IXs gapped at .035
