Jeeeez Mark, I feel like you think I'm being a smart as, a jerk or something. Until now, i had no idea how much power your engine is making. Do realize that the forun is alot like a computer program, crap info in, crap info out. Since you failed to provide ANY decent info to begin with, any and all fustrating feelings your having shouldn't be placed on me.
And yes! I LOL hard about thinking that 450 HP is to much for a daily driver. IMO, it's a "You gotta be kidding me" HP level to live with. However, this is also something that grandma may find way to much and someone else find piss poor for anything but grandma.
I personaly know people that run more powerful engines than yours everyday except poor weather. Seriously, what makes you think your engine isn't good enuff for everyday useage? To much power for the street is only a point of view as well as the cars set up.
Why is it a Ha ha ha ha on me for running 400+ HP on the street.
Is it not good enuff for you?
Does it make me un-qualified to answer, try and help you?
If you don't like the answer, perhaps you should start with better info in, a it of understanding from others and get off your I'm better than thou throne.
At your current HP level, good luck, you go figure it out via a few muffler swaps.
