im pretty sure its not normal but i really dont know.. it almost sounds like a boost leak like a huge one yet.. cars faster then its ever been... only thing i can say it seems like it started when i put the headers on long ago(about 2 years) but im not sure... i have eurocharged midlenghts. i did recheck the bolts when i first did it but wouldnt it sound clappy if my headers were falling off? im lost here.. its only under load, can it possibly be a bad ps pump(mines kind of junk) or a idler or somthing flexing on load?... i can rev the engine sitting zero noise, sounds like it should, very confusing... windows up cars completly quiet. windows down, sounds like a have a procharger lol only way i can explain it, under load only.. car runs strong does 10.5 lbs as it should on the 83mm with complete free low intake and exhaust... only reason i bring it up now because i think it seems louder now, maybe im crazy.. would love some input. did a stupid butt dyno app car made 580hp and 617tq... it just doesnt seem right.. car being a slighlty older platform its hard ti find one built with full bolt ons pulling at you in a video but im pretty sure all i should hear is blower whine not procharger whoosh
