Hi all, I am still considering my NOS options and whether to invest or not, Trevor has kindly provided me with a cost, however, I cannot stretch to a controller , so my question is , my car is a twin turbo Auto, should I use a WOT switch ( this concerns me as being an auto it will change up and down at will, and in theory I could go WOT off the line and from tickover, or should I use boost pressure to control when it kicks in, currently the meth systems are configure to activate at 14 PSI, Or should I do away with automatically bringing it in at WOT and just have a push switch mounted to be pressed when I want to inject Nitrous but still use the pressure controller to ensure that it can never come in at less than full boost ??
Thanks

You have sort of answered your own question Z32.
You have the meth set to come in at 14psi. But 14 psi could happen very quickly depending on the load the engine see's off the line regarding traction / engine load mainly. I would prefer to set the nitrous activation on your setup via an rpm switch. You should use a WOT switch to primarily arm the nitrous
but have the final rpm switch to activate it I think.
