Maximum Speed

[kbui]

What's the coeff. of drag for the C5, got to be pretty big for that large frontal cross section. Maxing out in the 160's-170's sounds about right.

off by about 10mph. 174.4mph.

It could be, I haven,t done all of the math yet. But I was there when the guy did 172 in a stock SS-2 . They did an article in one of the hot rod magazines( I can't remember which one off hand) I have built up quite a few late 60's muscle cars for myself and you kind of get a feel for where the cars limits are. And maybe I am wrong but I have a feeling the 2010 SS has the balls to hit 200 or close to it with minor modifications. The drag isn't as much as you would think, look at it side to side with stock NASCAR

Thank you PoorMansCamaro you apparently knew were to look for the info. I was off by 2.4 MPH so I undersold it I guess. That is definitely better than exaggerating I suppose. The only thing I care about is getting the new record I live in Tooele, Utah The flats are about 3 miles from my door.

Look at the Vettes. It's about 500 lbs lighter and have much better aerodynamics and didn't get to 200 on the same engine. NASCAR was lighter, more powerful, lower and have everything taped off to reduce drags. force/power needs to be increasing by the velocity square. It takes a lot of power to get to 200 unless you can greatly reduce the drags.

Yes and like I said, balancing the engine and/ or installing a higher final drive gear could make either one reach that speed. How do you think Hot rodders can make a 30 year old engine block handle 10,000 rpms? They balance the components, stock component may be close but they are not perfectly balanced. Unbalanced weight in your drive train is about 80% of the reason the typical engine red lines at 6-8k rpms. So if your current Camaro SS2 could handle 10k then what would your top speed be?

i hit 155 in 4th gear. i think 4th will top out around 165-168 some where in there. 5th gear around 200mph

Wow, that is pretty impressive. But I am still stumped why are people talking about maxing out 5th gear? Am I mistaken or don't all of the 2010 SS's have 6 speeds? I mean I know I have the paddle shift ability but I know that I have the torque to max out 6th. Is there some person out there who thinks you don't have the pull to hit max speed in 6th? lol

[halo8hkk]

did a little research.

1st gear 55.8mph
2nd gear 81.1mph
3rd gear 117.5mph
4th gear 168.0mph
5th gear 200.0mph
6th gear 294.85mph

i dont think a camaro will do 294
this is for a manual by the way.

Well you are probably right, but that is just because somebody hasn't figured it out yet By the time you reached those specs it likely wouldn't resemble a Camaro anymore. But I bet it is a hell of a lot easier to do with the LS3 engine than it would be with a 68 Pontiac 350 It is amazing the difference that electronic programming and fuel injection has made.

Wow... can we get an icon for Necro'ing a thread


First off, I am not a physics major, but I paid attention in class and I read way way way too many threads on here

What you are going to be fighting trying to get your car over the 200mph barrier is going to be ALOT harder than you think. In a nutshell, the faster you go, the harder wind pushes against you, i.e. drag. Take a moment to read post #7 by DGthe3 and number 9 by coolman in this thread http://www.camaro5.com/forums/showthread.php?t=68405 After reading those i think you will have a much firmer grasp on just what you are asking the Camaro to do.

You are going to need about 200+ more HP over stock to hit 200mph. Its simple physics. A car with the frontal area of the Camaro and a drag coefficient of .35 is simply not going to be able to push 200+ without a blower or some N20. The thing to remember here i think is that your working against an exponential increase, which means even though you might only be 20 or 25 mph away from 200 stock, those MPH are going to cost more and more the closer you edge your way up to the barrier. Also keep in mind that from what i can tell the figures in that thread (650+ hp, etc) are only based on the drag from wind resistance. At high speeds it might also be necessary to include calculations for a whole host of other friction related drag types, ie the friction of the tires on the road, head/tail/side wind, DA calculations, etc.

And realistically you could probably get another 1k red line with a completely perfect drive train. But even that would probably get you close to 200. Or if you switched out your final drive gear from a .57 to a .50 like the challenger has that is a 14% increase in speed to your RPM's (If I did the math right, I am tired) It all comes down to having the torque to hit the same top end rpms in 6th. And I am a firm believer that the SS has the high end torque to do it. The engine seems to have a lot left in reserve in the 150 range. That is my opinion anyway.

I had some thoughts along these lines with respect to the Daytona and Indy pace cars...I mean the real ones on race day. I'll bet GM has them tweeked
