Top speed electronically limited?

[FRKNlo]

Caculated using specs from the wiki.
I got as close as possible to 6600rpm max with whole #mph.
6M

• 1st 54mph@6576rpm
• 2nd 78mph@6533rpm
• 3rd 114mph@6596rpm
• 4th 163mph@6595rpm
• 5th 194mph@6593rpm
• 6th 286mph@6596rpm
• Reverse 49mph@6503

Where does redline start?

[SGOS252382]

Maximum speeds (redline) for the auto and (manual) SS
1- 37(52)
2- 64(81)
3- 99(111)
4- 132(159)
5- 180(189)
6- 227(280)

I saw a list of top out speeds per gear on here for the SS a while ago and am having trouble finding it, anyone remember that or what section it was even in?

Thanks .

There is a graph running around here that shows RPM/MPH for each gear, is that what you're talking about?

That'll do fine, there was a thread where members where listing their personal experiences but a simple graph would be fine as well.

[daphatgrant]

You don't know what section that graph was in do you?

I was hoping someone else would post it. I saw it here on the general boards, but I don't remember anything about the thread. If I HAD to guess I'd say look in either transmission or the differential boards. If you change your gears there is bound to be someone asking what RPM you would be running at a certain speed.

Thanks , when I find it I'll link it in this thread so searches might bring it up.

I posted this the last time it was asked. Glad to do it again.

Per Road & Track June 2009 Camaro SS test:

1st 6500 RPM 52 MPH
2nd 6500 RPM 76 MPH
3rd 6500 RPM 110 MPH
4th 6400 RPM 155 MPH*
5th 5400 RPM 155 MPH*
6th 3650 RPM 155 MPH*

*Electronically Speed Limited

I believe Road & Track's "hard numbers" to generally be accurate. Obviously, with a simple electronic tune you could remove the "Top Speed Limiter" (and your warranty!) to increase the top speed in the last three gears.

I've posted a graph of this before. It was in a thread titled 'best gear for 75 mph' or something like that. The graph is for an M6 SS. I can throw it up after work today along with a couple others. If you want one for an auto I can throw that together too.

This one? I posted this in one of the camaro vs. mustangs thread "Prove moderators wrong". The 2010 SS numbers are mildly different from what ART-2008 posted....probably due to a small difference in tire diameter that I have on record.

Excellent guys thanks very much .

As promised...

Assumptions:
1. Drivetrain Losses: 15%
2. Driver weight: 225 lbs (I wish...gained a few since I wrote this code. Working on getting back down!)
3. Altitude: 935 ft above sea level
4. Camaro SS, M6, LS3 torque curve approximated from here

Limitations:
1. Rotating mass is not accounted for; however, this will have negligible or no effect on top speed calcs, only acceleration. Numbers do seem fairly consistent with g readings taken on Hennessey's quarter mile run shown on YouTube (As Seen Here).
2. Due to transient nature of launching the car from a standstill and my lack of knowledge in this area (I'm an EE not an ME, cut me some slack!), the graph starts at 1000 RPM in each gear.

Speed vs RPM and theoretical top speed of each gear (not drag limited)


Net Accel vs Speed and theoretical, drag limited top speed of stock 2010 Camaro SS with speed limiter tuned out


Yes, by my calcs, the theoretical, unlimited top speed occurs in 5th gear and is 175 MPH. I didn't show it on the graph, but 4th gear would be good for about 163 MPH at the rev limiter.

lol wow, look at that drop for 6th. Physics is a b!@#h!
