Plugs for street driven 500whp motor/200hp n20.... Ok guys I have searched for the past hour trying to find someone with this set-up. I know there has to be a TON of people doing the exact same thing, just cant sem to find them by searching. So here is my set-up. Its a 404CI that should make 500+to the wheels, and I will spray a 200hp shot through a NOS plate kit. Last time the car was together I ran a 150 shot with 505whp. Made dead on 650 to the wheels and 740tq. I used tr6's gapped at .045. Never had a problem with them, and it had plenty of power while off the jug. I am planning on making a touch more HP with the new set-up and will bump the jets up to the 200 sot. I am probably going to go witrh some ngk tr7's. I am just wondering how the 7's do with a car that is street driven on motor 90% of the time. Will these plugs hurt my performance a bunch? Also what should I gap these plugs at?

I run 7's on the street and am going to switch to 8's for the spray. The 7's have run just like 6's on the street for me. I have not had any problems and they are doing just fine.

i've only sprayed my junk a few times but i'm curently using the ngk tr7ie (iridiums) they have worked great so far.my next set will probably be an autolite of the same heat range or the ies again.
