Something doesn't sound right..

Where is your info coming from?

This is from Dodge, everything about any car I use is from the car company. In the way of Dimensions and such. So what doesn't sound right? The only think I had to assume on is the percent lost, and I think 10% is more than fair.

this has to do w/ the speedo being off like they test w/ motorcycles at high speeds...motorcycles are a lot more off in these cases tho. They can be off as much as 15 mph.

 

I was a little bit off on that and it does differ for each car depending on frontal area, and drag. Nevertheless a good rule of tumb if you don't want to use the equation is 5 mph=1hp for speeds above 190. With the viper I think it came to about 4=1.

 

More than likely you are right. THats why I believe in GPS and lazer with the midde being the true speed. Not many companies are testing that way, but I think Ferrari is one. A good example of that was there 550. Everyone was saying it would do over 200 but Ferrari said no 199.

 

The drag on the Viper.. no one here agrees with what it should be. It was a discussion in the past. The Viper needs to be more aerodynamic, not a moving brick..

I totally agree with you. The viper should have a lower coefficient, but all my numbers on the viper; I get from Dodge. If you look at the G35 coupe. It has a CD of about .29, and it makes no lift. THat is crazy to think about. One of the easiest ways Dodge could lower the vipers drag is to put a negitive lift plate on the viper. In other words coat the bottom of the car so that it is slick. That alone could drop the Cd by .05-.06 or so.

 

i was just wondering, who was drivin it? some 190lb guy?

 

190 is the estimated top speed, not weight.
