Lag is very minimal. It builds boost nearly instantly if the kit is done correctly. I would highly reccommend you get ahold of Gus Bohne on here. He does more ice racing with turbo doo's than anyone else around.
YES! I had a Gus Bohne set up on my 800 turbo doo all last year. NO LAG AT ALL. U pick your leave boost #. I ran 4.9 101mph. on grass 500ft. with trail studs and stock suspension at 720 lbs. in Hastings Mi. Call Gus....603-401-8897.
