Hi
I have a 2010 Challenger.
Do these cars have a limited computer top speed?
Has anyone been able to reach top speed in their SRT8?
What was it?
Doc

I'm not sure about the SRT8 but the R/T is 142. You can fix that real quick with a predator though.

I know the 2008 can get close to 180 mph. I don't believe it's limited other than by the limits of the car. Others may know for sure if there's a physical limiter on there on not for sure.

The SRT's speed is not computer-limited- only drag limited. The top speed is 173 mph. Some members have hit this on super highways in Germany and Italy.

Don't think there is a limit. I hit 164 with my 09 SRT.

Someone on here has a pic posted at 193 mph and I even heard someoen claim 203 mph.

I hit 195mph @ the Daytona Hi Speed ring
(Grand Turismo 5 - PS3 ) :laugh:
I believe it. These cars are beasts.

I remember seeing a video where a guy hit 183 at the Mohave mile. He lost the front spoiler at 140.

Aerodynamically, the Challenger SRT is limited to 173 mph. Look at what happens when you try to drive a retro-style car at 200 mph.

I thought the SRT was computer limited to 168mph unless removed by a predator and that was because above 168mph you ran into integrity issues with body parts (i.e lowlife's one mile speed runs). I also thought the 2011 were computer limited to 180mph because of the re-worked front spoiler duct work allowed a higher top end.

SRT Engineers have confirmed no electronic limiters on SRT8 Challenger.

I read in another thread that the limiter in both R/T and SRT is based on RPM. I remember the R/T is limited at 5800 RPM (around 145 mph) and the SRT at 6400? RPM (170 mph). The speed will be a little different for each car and different under varying conditions.

Anyone else read this?

No limiter. R/T's were limited due to tires. Not sure if they changed that when the STP was made avalable. Probably not, but if it gets the F1's, it could do without the limiter.
Mustangs and Camaro's are limited due to tires as well as I've been told.

It was a 7 part video. Too much traffic and rain in Germany, but he hit 169 mph in Italy on a Sunday morning. He had concerns about the sunroof at about 130. The videos were put up as I was typing lol

If you open up the exhaust and airbox, use a 6 speed instead of the 08's auto trans, you might get a few more mph out of it.
Hard to say, I don't think I've ever seen the difference in top end between the Auto's and 6 spd's. Less drivetrain loss on a 6 spd, but the auto might have different gearing?? Can't remember right now and too lazy to look.

There is a gearing difference between auto and stick. For an SRT8 with F1 tires these are the approximate RPMs at 170 mph:
Manual trans 5710 rpm in 5th
Auto trans 6020 rpm in 4th lockup

As the maximum engine HP is reached at 6000 rpm, you would think the top speed of the auto trans model might be 1 or 2 mph higher than the stick car.

If that's the case, wouldn't the manual tranny have another 290 rpm left in it; therefore, increasing the vehicle's speed over what was achieved at 5710rpm? What would be the manual's speed at 6000 or 6020 rpm?
