So if the top speed limiter cuts in at 150 mph on this 2010 3.8 stock...i am wondering with a cbe, sri, lighter pulleys and a re-flash would yield with the manual? 160 mph?

Not sure about the GCs.
My '06 Altima had a 142 mph limiter which could be reflashed for complete removal of the limiter. That said, I never did the reflash, but did check the limiter and my car did make the 142 limit in stock condition. The '02 Altimas came without a limiter, and a friend of mine hit 160 with his on the Autobahn in Germany! His car was bone stock!
I'd be willing to wager that our GCs can be reflashed for removal too. Guessing the 3.8 to be able to make at least 170!

Ever hit 150? It's definitely outside of my public road skill level hahaha Either way I'm sure a reflash will solve that for you.

I've hit 138 according to GPS in slightly modded 2005 350z. Wasn't even working hard. 147 in a bone stock 370. Nothing to it. And 139 according to GPS in my stock '14 3.8. Barely broke a sweat. It's aerodynamics anything above 155.

I don't think you want to go 160mph on this car, let alone a 2010. There is a point where it's probably drag limited.

At those speeds and over the fuel needle is very noticeable in its movement down.

...What do you mean by "let alone a 2010"? I was just curious about the top speed thing. I have been up hovering around the 150 mph mark a couple of times. Probaly a couple of times too many. 150 mph in a car is a little scary. On a bike.....the fun is just beginning.lol. The sweet spot where the car feels like its in its element is 100 mph imo.

I think I could prove you wrong on that point!

there's not enough differences in aero between 2010 vs. 2013 to call one significantly better than the other.
stock, both will start to lift and get unstable at high speeds. you don't solve that without lowering, installing a flat bottom skidplate under the entire length of the car and a functional diffuser in the rear. To my knowledge the 2013 has none of these.
Removing the limiter nets you maybe 10-20mph before drag exceeds acceleration capability. Never been that high, I don't see the appeal of beating the crap out of an engine in an overdrive gear.

I've driven both the BK1 and BK2 (stock) at high speeds. My conclusion from that experience was that the BK2 felt more planted at high speeds, while the BK1 was starting to scare me at the 100-110mph mark. Only reason I made the comment

I definitely felt the floating when my car was stock. Sticky tires, lowered and custom alignment it obviously feels a lot more planted at higher speeds - still lifts a bit but the steering still feels nice and connected.
Still won't bother doing a 6th gear pull though

You should be able to tick off 160 no problem.
I could hit 150-155 in my 2002 mustang GT stock (260hp, 5MT). Just took a REALLY long time once you hit 5th. Ive seen 165 in my Cobra before letting off, out of fear of melting pistons. Still was pulling nicely at that point. My days of having cars where the speedo moved at the same rate as the tach in 4th and 5th are over lol.
The fact they speed limit you to 150 should tell you theres more. If the car physically couldnt reach 150 or more they wouldnt need to limit it.
Also, make sure your tires are capable........

I'm sorry to hear that. It must have been a terrible experience.

Not really. If it werent for their age id buy another, but alas, a car from 99-04 wont be nearly as reliable as my gen that has a warranty so I dont have to do **** lol, and I need a reliable commuter. I played with a 99-04 GT earlier this month and it was dead nuts even. If I had half the drive and another car id consider one or a Mach1. Great cars for the price. Still enough power to have fun with, and the 2v modulars are still the best sounding v8's ford has produced.

Feel free to go 160mph. Let me know how it goes.

#1 I don't feel the need for a reflash to prove my point.
#2 I know for a fact that my friend, in his stock '02 altima did 160 on the Autobahn. If he got 160 out of that big 240 HP box of Velveeta Cheese, a GC, which is many times more aerodynamically swift would make that and more.
#3 Your video shows an idiot on dirt or salt flat doing 160 and rolling it, he needs to have rolled it. What an untalented moron he was.
#4 I'm 70 years old, and the older I get, the more my brains cut in, so I would not do that again! I was only 65 when I did my 142 run!
#5 I actually got 142 out of my stock, except for a CAI, '06 Altima, and the thing held the road...new asphalt highway, quite well! That Altima actually weighed in at about 300 pounds lighter than does my GC, and was running about 260 HP. My GC is much faster 0-60 than was my Altima. Oh, yes, I'm a pretty good driver!

I live in Germany and have the 2012 Track 3.8 6spd. I've driven this thing flat out in the few places where traffic and road conditions will let you. It's scary/nervous the first time and even the next few times. You sit quite low and it looks even faster than 150. The car doesn't feel solid. The stock suspension is already enough to make it briefly lift a rear tire when going around a curve at 120 mph (not a sharp curve, just a long autobahn curve that I should have taken at about 100 instead). The traction control light comes on and you lose power for a second. I've done a wheel chirp at 90 mph when hitting a pothole under throttle causing the traction control to come on. I had a 1995 BMW M5 with the limiter removed at 180 mph many times and never felt as nervous as I do with the Gen. When I get in the curvy section between Ramstein and Baumholder, I take the curves slower than the people in the Passats and Skodas because the ruts in the road make the car squirrely and sometimes I feel that it's not going to stay in my lane.
My tires are good. The alignment is good. The suspension isn't broke or worn out. I just don't believe the car is really made for high speed driving.
My 2 cents

At those speeds you should be watching to road, not the fuel needle :grin:
I've hit 130 racing the wife. That's plenty fast for me. I'm more into the twisties anyway. 130mph + twisites = deadsky.
I have had a Pensky moving truck fully loaded and towing my camaro at 120 by accident. I only noticed because the truck cut out and scared the sh*t out of me. The truck was smooth at 120 though
