a sound that has me a little worried.....
It seems to be comming near the fuel rail/heads area, i cant really tell b/c the supercharger is so friggin loud, anyway it sounds like a "plunk" not too loud, in fact i can barely hear it. I dont think is related to the heads, this started after i installed my stealthram about a year ago, but i havent really drivin it since then anyway i can hear the sound on both sides of the engine compartment, any chance it just might be injectors turning on and off ?

Injectors 'click'... Not sure about a PLUNK... Maybe some lifter noise? I don't know...

You can remove the supercharger belt to get rid of some of the noise and then youll be able to hear the plunk better. That might help narrow it down.
