Before I got (and fell in love with) my Stang, I was going to get a G35 Coupe. I registered on a popular G35 forum a while ago. Now that I got my Stang, posts have been getting kinda ugly over there...

I know, I know...don't bother fighting with fanboys over the internet...but I have to admit, it's kinda fun. It's a nice break from writing code all day.

They love harping on the "crappy" live rear axle. They keep asking me how I'd feel if I hit a bump going 150 and flying to the moon. They also claim they would beat an 05 GT in a 100 to 150 mph race because of their 6 speed transmission.

Does anyone have anyone have any high speed stories? The fastest I've gotten mine up to is 120 before I chickened out (scared of the law, not of my Stang's capability), and to be honest, it felt very stable.

Has anyone gotten to 150? How did it feel?

So, is the G35 now anti-bump resistant?

Anyone who hits a bump at that speed will share the same predicament specially since nobody trains for such scenario.

The 6-spd might be a factor but common sense says whichever hits the high speed first will get the flag.

If the G35 can achieve 150mph then it will win. Based on other posts here, the mustangs top speed is about 143 (drag limited) if I remember correctly. That being said the mustang (stock) could never win.

I was driving on the interstate at 3am on a weekday so I took it to 143...handled it brilliantly, just as it does at 90. I read somewhere that somebody with a Vortech got the car up to 198.

The 05/06 GT wont go 150mph? I find that kind of disappointing since I remember driving my 95GT 147mph bone stock.

Someone race a G going 100 to 140 and post results please...=)

G owners are sooo snooty even though it's an ENTRY level luxury sport coupe. Whatever, it's only 6k more than my Stang, but they act like it's the difference between a Maserati and Ford Focus.

So far as I know, a 6 speed tranny essentially has 2 overdrive gears in it. If that is true, then it wouldn't make any difference in a race.

Was the car modded in any other way to handle near 200 mph speeds?

Thats the number that is published anyway. It's drag limited though, not governed. There was another discussion on here about a lower gear (ie 4.10's) might be able to yield a higher speed

I had mine to 135 and it was still pulling very strong. I've removed the speed limiter and I have no doubt in my mind it will make it to 150 and prolly farther.
Daughter just moved to Montana and I'll be making a road trip in the next month or so and you can bet I'll find out! As far as the G35, I think it will be operating on some thin air at the speed.

Correct me if I'm wrong, I'm new to modding, but don't higher ratio differential gears mean lower top speed, but greater acceleration?

They (most) have one, they stick an extra gear down low (1-4th, before the 1:1 gear) to keep you up in the powerband more efficiently.

But with that, a GT should have no problem slaughtering it after 100mph, once you're in 100 they have lost the benefit from the 6spd, and they are now in either late 4th or 5th, so you would have an equal chance gear wise. We would be in 4th all the way through over 100.
While they have less power, if they had close to or equal to the GT, in a straight line their powerband would be tighter, and that's where the 6-speed benefit comes from.

Someone said that there wasn't a speed limiter..don't know though, don't have my car yet

That's true but some pondered that the higher gear ratio might be able to overcome the drag coefficient therfore netting a higher top speed

Governors set at 115 from the factory, can be removed with a flash device -easy.

2.11 will have a slower acceleration but higher top speed than shower 4.10s, which will have more acceleration but alowered top end

Seems to be a little misinformation going on here. I'll clear it up.

GT's are governed at 143, that's not a drag limit at all. It'll have no problem going 150+ without the governor. Drag limit will probably start to kick in at around 160.

V6's are governed at 115.

To the original question. It sticks like glue at very high speeds and is very stable. I've had it to 145 on some rather rough sections of highway and never felt out of control or even close to the edge at all.

My 72 year old father in law had it up that fast as well, and was doing S turns across both lanes of a crowned road. He loved it

I got mine up to 145 the other night before I slowed down. I imagine I could have squeezed another 5 mph out of it, but who knows. I have only put on some Bassani mufflers and I lowered it. I haven't flash the computer or anything either, I'm suprised I didn't hit any limiters.

A few weeks before that I took it out to some road my friend and I went to and got it up to about 135. The roab is a little bumpy and it felt like I was flying around whenever I went over one. We left after the first run, heh.

The speed limiter can be removed, as long as the tune you are flashing has that option. Mine is gone (like the Camaro)!

Do you just find someone that has a computer thing to flash your car for stuff like this? Also looks like I need a bigger speedometer!

No, you have to spend the money and get a tuner. The only way to use a tuner from vehicle to vehicle is to re-load the stock tune from your tuner back into your vehicle.
