Driving home late from work one night I came to a flat opened up spot on the interstate. I wasnt plan on going too fast just to were I got uncomfortable. It actually was smooth the entire time and felt I was in control up to 150mph. Car felt comfortable but seeing 150 on the HUD made me think otherwise. Will probably never see even close to that speed again. I do see 100mph every so often which seems like nothing anymore

Do the 2006's have the limiter set lower than the 2008's? I had my 2008 GXP on the Dyno and the limiter shut it down at 160. It was pretty close to red-line in 3rd gear, but I had about 500 rpm to go.

100% bone-stock too. I need to get an intake and some exhaust on there. Tune out the fuel shut-off and go for it again.

I got mine up to 130mph,.....ran out of room but it was still more pedal in the Crusader than I thought it would be!! My Nexen Tires feels real good, no vibration at that speed.

I had mine up to 135 a few times but have yet to top it out. There's one stretch of road here that goes for about 50 miles almost in a straight line but the Texas Highway Patrol are crawling all over it.

Well according to the mags, the SS cars speed limiter was 155mph, and the GXP cars was 143-145mph, but i was messing around in the snow and my spedo went to 160, just taking traction off, and flowring it to see how high it would go.

I've hit 150 in mines and it didn't shut down. I was expecting it to stop me at 143.

I hit 153 in mine last night while racing my boss in his G8 GT on I-10. I let off because I came up on traffic. Governor on my ride is set high enough for me (stock tune), I guess, lol. FYI, the G8 GT didn't hang with me. I blame the driver and not the car though. (no *****)

Definitely driver. My brothers G8 GT just beat my SS. It was a decent race from a 20 and 25 roll. He started eating me up on top, we stopped at 100. Had we went passed 100, it would have been worse.

Be careful doing that, Mixerda bent a bunch of valves leaving it in 3rd at those speeds.
