I think 20-30hp you might be able to feel, but it's hard to judge. I know I can tell the difference between my 95hp 1991 Civic Si and driving a Mustang Cobra SVT this past weekend with over 300hp :loco:
5 hp... no. 20-30 hp... a lil. +60%... goes w/o saying

my step dad bought an 03 cobra brand new... pushing 430-440 hp right now. lol, quite a jump from my sol's 120-130 hp
