I am trying to figure out what gen whipple is on my car Its a stage 2 with TB and 72 lb injectors w/ duel fans. I dont see anything listed even in older adds etc with the #s on the blower case. Its a 2015 GT. On top of the whipple on the polished plate on the top is stamped 175F-410. on the side of the same polished plate on pass side near fuel rail is stamped 175018-136 revB 07/13/15. I searched old posts and see with the date and straight ribs its not a gen 3 as its to old. everything I see online seems to state the 2.9 kits as 175AX?.
