You might want to put it on a chassis dyno and see what your air fuel ratio is thru the entire power band. This would verify what horsepower you're putting to the ground and see if it adds up somewhere. Like everyone else said my car also runs mid 11's and it might be in the 450 to 500 hp range and with the driver it weighs 3260. I tried to scan a time slip for you to compare a 11.48 pass to a 11.10 pass but scanner not working so I typed them in for you. My car #102 did the slower pass of 11.487 very close to what you ran.
