[quote=NP6000]I never said that these cars don't have rev limiters. I said they do not top out on their max speed due to hitting the rev limiter in top gear.

They run out of power to overcome aero drag prior to redline in top gear.

what are you talking about. that's exactly what you said...

"Most high end cars capable of high speeds are not speed rev limited. "

To say that they don't hit the top speed in the highest gear because of drag is quite obviouse... I don't know where I said they didn't, or did. all I was saying is that the high end cars aren't limited by the manufacturer with speed caps at X MPH/KMH... that's all. wind drag is a completely different factor, and with enough of a head wind they wouldn't hit 100 mph, so your statement is irrelevent to what I said...

"Well I assumed he was talking about a Rev limiter. just about every car will have one of them, with varying points of cut-off... Now of course that limits speed, because your speed is determined by RPM, and Gearing, but still."

^^^

This is where you say speed is determined by RPM & Gearing. No mention of Drag.

My point was that german cars are electronically limited to 155mph, and are sometimes disabled by owners who wish to do so. Most Domestic vehicles also have speed limiters.

This is where it gets into the grey area. that is not true. Speed is directly related to RPM and gearing... Drag is an outside force that acts upon the car, and does affect speed, but saying that drag is a factor on speed, is no different from saying that a hill does as well.

About the tranny issue, smoother shifting back in the older days in cars like Cadillacs, Lincolns and most anything else was accomplished by keeping the clutch bands somewhat loose so that you woulnd't get a jarring feeling when it shifted. That definitely helps to shorten tranny life since there is excess heat built up when the clutch bands slip. Nowadays, the computers cut back on timing and possibly fuel as well to limit how much power the engine makes during the shift. It might only be for less than a second, but its easier on the gearset to not have all that power going through the transmission when it shifts. Kinda like if you are powering up a hill in your mountain bike and you shift gears while still hoofin' on it, rather than backing off during the shift and then get back on the power. My comment about the SRT and it's faster-shifting tranny wasn't entirely accurate about the clutch slippage hurting the tranny. It would be more about the 425 HP being sent through it while shifting and the torque spikes that occur during auto tranny shifts.

I like my Magnum very much. It handles very well. I don't get any tire screeching on turns or excess body roll. Miluni, did you have the 300 or the 300C? Only the C has the Hemi, and the better suspension and 18" wheels. My car even has the self-sealing tires which aren't exactly total high-performance rubber but they grip the road quite well.

So it sounds like the 171 mph top speed could be genuine, and another person said they hit 167 mph in their grandpa's 300C. That's pretty darn impressive IMO. I recall seeing somewhere that my Magnum has a 2.82 final drive too which is pretty tall. Great for high-speed runs if you got the power. Probably also why when I punch it off the line, my R/T barely spins but just hauls off. You might think 340 HP and 390 ft-lbs of torque would make a tire-roaster but its not. If you DO get the tires spinning though, it will roast them up to redline in a hurry.
