i hit 155 the other day on the highway (not advised) but i HAD to test out my newly built engine. i had a custom stroker kit made, and higher compression pistons 12.9 and nitrous, and exhaust cut out, and Short Ram Intake. that was aparently my engine can take 125 shot of juice
I got up to 133, according to my speedometer in my 2000 GT manual on the 101 Ventura Freeway by Santa Barbara, slowed down when I saw headlights pulling onto the highway from an offramp, and got a speeding ticket from CA Highway Patrol for going 85 mph.

based on the gear ratio in 5th gear for a GT, and on stock rims and tires that max speed is 137.5 mph... add bigger wheels and you can go faster a little bit... but not much...
That is if there was no friction & air resistance. Its not the gearing or the diameter of the tire that determines the top speed, its wind resistance & horsepower or the lack there of. You cannot calculate the top speed, there are too many variables to consider.
i'm saying that with ANY power and any wind resistance the fastest you can go with a 5 speed GT with stock gearing, wheels/tires, and redline is 137.5... you cannot go any faster because the car will hit fuel cutoff...
topspeed can be calculated, aerodynamics doesnt come into play so much because our engines produce enough power to bring us to what the cars actual top speed is given the stock redline and all that junk...
i hit 138 too. what's up with these '00 gt's only goin 120 or 115. i have 18's too. i heard that could make a little difference b/c the diameter wheel. for all i know i maybe hittin 140.
I call bullshit, because GT's top out at 127-130 I don't remember exact number.
that may be as fast as you've gone b/c your too scared to go any faster.
i'll prove it to you if somebody can tell me how to download a video to the internet. i hit 138 numerous times in my '00 gt. i raced a friends v6 honda accord every other night at work on the way home. i got him all the way until we hit 125 then he gets even with me. i hit 138 and that was it. he kept goin and had 2 cars on me(goin 140 he said) i didn't have anything else left, but i'll prove i hit 138 if you don't believe me.
Here's a pic at just over 200kmh look at the rpms...Again, I accept that the spedo is off at that speed, but that's just the numbers I go by. But it climbs REALLY slow at that point. I've hit 220. I'll take a pic next time. I'm putting on my summer rims this week. My stock tires are wearing down and I don't like to go much over 140kmh on them.
140-142mph 6spd gts i cant get it to go any faster, it just sits right there , it wont gain? ill be in lift and it will stop at like 64oo rpm, i think thats were it tops out, or maybe it just cant fight the air past that.
