20psi + ignition

below 25 on race gas, and below 30 on E85 I would most likely stick with 7's gapped to .020 - 022, above that I would switch to 8's. Every setup would be different. This is assuming everything is sized properly and adequate cooling of the charge air.
 
i use the ngk vpower 9..its this bad?i have ingition problems on high rpm?!

Shouldn't necessarily have problems, they will foul out fairly quick though. What are they gapped to? Brand new plugs still cause issues? How much boost? What fuel? What compression Pistons?
 
cp 9:1 ,100 Oktan gas, sparkplugs gapped to .020 ,1,5 Bar(21,7 PSI)boost....
around 7000 rpm misfiring,but not always...
 
Sounds fancy ! You can use "my" idea . This is best what you can make for that money works ok over 1000 hp supras with RE85 !
