I wouldnt doubt more than that depending on what your putting in your engine. My tuner estimates 700hp with what I got. Thats before water meth haha. I did all my own fab work, just need an exhaust shop to put in a 3" to dual 2.5" adapter. Thing is way too loud the way it is right now. And when the bov pops it shoots a nice water meth mist haha. Sorry I keep rambling just took it for the first drive today. Dyno tomorrow
What size turbo you putting on? What water meth kit?
