" Although this is purely mathematics/physics/theory - but given the M3 weight of 3500 lbs, and a trap of 115 mph, the following ET is estimated with a 1.7s 60ft: 11.8s
Given 400 horsepower at the wheels (not sure how possible that is, but I would say it could be) and 3500 lbs we get 115.5 MPH and 11.78s
Given an ET of 11.99s and 3500 lb weight, we get a calculated WHP of 401.33
Three different 1/4 mile calculators (calculating power from ET/weight, ET from power and weight, and ET from a 60 foot and trap) - all within a few percentage point variance of what MIGHT be possible. I am not saying it is -but mathematically it looks like it would be if you had the conditions. I know people hate bench racing - but physics is what dictates results in my book.
I honestly am curious now. I need to get a test pipe - primary cats suck the power out of this car... "
