Supercharged Mustang 1/4 Mile???
Has anyone seen any times/speeds for 1/4 mile for 2015/16 GT's that are Roushcharged Mustangs with big sticky tires? It appears that "traction control" hurts the times Mustangs run.

When going to the track ALWAYS turn off traction control. If it is on you might as well not even run. Your times will suck.

I noticed that big time! With the traction control off & stock tires it will be quite a challenge if not near impossible to run a decent time. I suspect with the best tires my car would be approaching high 11 second runs in the 1/4 mile. One benefit of stock tires is it protects the driveline. Not being a racer, I'd rather have tire slip than broken driveline parts. I suspect 670 HP with slicks could give you a few broken parts now & then!
Slicks for a manual car, drag radials for an auto.
If your car is equipped with launch control, that also won't help you.

Join the crowd in the "Off Topic Politics Section" & tell us about the politics & medical services in Sweden! Americans are convinced anything but our medical system will cause us all to die! Be interested in hearing what the car culture is like where you are! Would you consider taking "Donald Trump" from us! PLEASE!!!! LOL!

You can expect what you want, but "realistically" the difference between 12.5 in the quarter & 11.0 seconds is a lot! I think tires are a major issue in drag racing. Stock tires on my car don't get it off the line, but then that's just fine because I don't street/drag race so I don't really care. From the Youtube races between a GT 350 & a Hellcat, I think a supercharged 5.0L automatic is likely faster than a Hellcat because of weight of the Hellcat! What I do care about is usable acceleration from 20 to 80 MPH, & the supercharged 5.0L is pretty damned fast there & I have a hell of a lot less invested in my Mustang... which has a value to me! For the average guy, I think a "stock" GT with just a tune/or not.... is the most bang for the buck. There is always someone faster, & a stock GT is pretty nice to drive!

12.7-12.8 is the 1/4 at stock.
Hellcats run something like 11.2-11.4 quarters, if you think you'll be beating them then you should def be in the low 11s, not the high.
Anywho, my point was that a $9k supercharger better put your times more then a few tenths of a second faster than a $400 tune will, even if you're running those stock pirelli tires
I can't seem to find any solid performance figures for Roush kits (just hp increases and whatnot), but I can't imagine the quarter time being anything less than a full second faster than a S550 with just a tune.
