Thes cars sure pull hard at high speeds

So...

I was cruising at about 80 mph the other night on a stretch of highway that had concrete barriers on each side of the road, was flat, and had no entrance or exit ramps on the stretch I was on. There also just happened to not be a single vehicle in front of me as far as I could see and any that were behind were WAY back there. So I said, "what the heck", let's drop her into 4th and give this thing a go...

I have dropped it into 4th going 80-85 and ran it up to 110 and braked back down to 80 in a matter of 10-15 seconds a few times, but never ran it hard and thrown it into 5th gear.

Well, I ran it...and ran it...and ran it. I threw it into 5th gear at about 7000 rpms (130 +/- mph) and this sob pulled HARD all the way to 160 mph and I let off the pedal and slightly braked back down to about 75 and the whole thing seemed like it only took about 10 seconds.

I know you need exponentially more HP to accelerate through the air the faster you go, (and granted I have modded my car) but it scared me how easily this thing pulled to 160.

I know its not the smartest thing to do, and I'll probably never do it again (unless I'm at an abandoned airport) but when I did something similar with my 2001 GT back in 2002ish it took like 45-60 seconds to creak up to 155. These cars now run up to 160.

So if you are curious, hopefully this answers any questions or thoughts and you won't try it yourself.

Yep, these engines deliver their true power in the upper RPM range...which is nice. The older 4.6's would basically run out of breath in the upper RPM's, which was always why the 4.6's always got the jump on the LS1's but then lost by 3-4 car lengths by the time they hit 70mph.

Yup these 5.0 motors just keep pulling. Every time I drive mine I still get that wow feeling when getting on it. With the 3.73's I find that dropping it in 5th will get the job done. I haven't gone that fast but glad to know it will do it!

So what would you say top speed is on one of these with 3.73 gears?

My 4.6 with 100 less horsepower really surprised me with how quickly it got to 130+ (and still climbing fast before I let off) so I can only imagine what it would be like with the Coyote. Still rock solid and not the least bit scary at that speed too, impressive.

When doing normal driving, I always forget that I'm driving a 400+hp car, because in lower RPM's, the car is so tame. Feels like an everyday car.

With the force of the drag increasing so quickly, I bet these cars could get to low 170's. With the suspension and the lowering on my car, I bet it could get upper 170's.

The talk of these cars going 185 mph is just not real IMO, unless it's planting 550+ to the street.

Heres a video of me on the autobahn... every pull is in 5th gear. 3.73 rear end.

I hit the governor at 150... I have just installed a 1 piece aluminum d/s, added a d/s safety loop and Michelin pilot super sports on all for corners.

I fully intend to take the governor off and see where this thing will take me.

I sure do count! You included me with that last comment. At 700 HP to the crank I should be around...... 590-610 HP to the street I JUST took the governor off about 30 mins ago so we'll see if I cant hit that 185 mark

Sorry...

Yes you most definitely count for that (and I am excited to know where you are at). I was referring to the virtually stock cars.

I brought my video up because I figure our cars are similarly modded besides the HP/TQ figure. I wonder if our top speed would be close to the same since our gearing is the same?.... : and like the other guy said. Try be careful on them american streets. I know in Colorado anything over 100 = jail time.

I wish I would have looked at where my rpms were when I hit 160...but I was more concerned with slowing back down.
