KIf i run 150hp shot of No2 is there an engine setup combination i have to run so i dont get any detonation? like back timing off and/or change spark plugs?.. im open to suggestion too im going to be using the stock 2000 ls1 cam shaft since the exhaust duration is more than the intake duration...

 

stickys have alot of good info, id say run a -2 colder plug and back off timing 2* for every 50hp of nitrous you are runing

 

150 shot I would go with a #7 plug non proj and back the timming off like above

 

so i would back off the timing 6 degrees you guys are saying for a 150hp shot
