Neighbor asked me what my N/A Roadster will do and I was kinda embarrased to admit I didn't know.

So, what CAN be expected from an N/A Roadster, unmodified? ( I assume an N/A Coupe would not be much different.)

 

From Motorweek

.......Jab the pedal, and this Crossfire romps to 60 in 7.1 seconds. With less than 100 pounds of added structural weight, that time is just 6 tenths of a second slower than the Coupe. The quarter mile passes in an equally spirited 15.3 seconds, at 93 miles-per-hour

 

You have to appreciate the car for what it is......and is not. It's not a drag racer. But ask your neighbor if he would like to cruise at 140-150....till it runs out of gas!!!!!

Of course, the trick is finding a place to do that!

 

Thanks DWS, and agreed Dan!

 

Take at least 0.1 of a sec. off those times now that you've claybarred and applied NXT 2.0 .....

 

Yeah, the Roadsters are a little heavier, so they are a tad slower. I've seen a number of different numbers for the coupe, avearging from about 6.0 to about 6.4 for a NA coupe (0-60).

MuscleFan21 on the Forum has track numbers for his coupe. Unconfirmed 14.38@96mph, Confirmed 14.40@97mph May want to check those out. Not sure if I recall too many roadster numbers but they'll be about a half second slower on average. Also, there are differences in manual times versus auto times. Again, I've seen them all in similar ranges with some autostick claims better than the manuals, but some manual time better than the autostick.

You'll find a lot of info if you do a search. Either way, it's quick enough and handles well enough for my needs -- and meets my fun factor.

 

15.3? Someone needs to learn how to drive ASAP or be fired...

 

coupe with an auto trans:

zero to sixty in 7.3 seconds stock
6.1 seconds after all my mods to date, but still waiting for my needswings CAI (on order)...

 

I can't see 100 lbs making a .6 second difference on a 3300 lb car. Proportionately, that's all out of whack. Maybe that "canvas" roof is not as slick as a hardtop. But who drives with the top up?

 

I would tend to agree with you on this, however according to some sources it's more than 100 lbs difference (at least according to some of the sources I checked out). The roadster alledgedly weighs 3174 - 3326lbs -- and the coupe 3060 - 3084 lbs -- so it is alledgelly ranges from ~ 100 to 260 lbs more -- which still isn't insignificant. Not sure which sources are correct. Not sure if there may be other vehicle related things that might affect the 0-60 claims but a 300 lb person equivalent in a car could certainly have an impact. Of course, one's ability to drive a car and get the most out of it (optimizing shifts, etc.) can certainly have a big impact.

 

0-60mph 4.07 seconds!
With better traction I think it could be under 4 seconds.
Oh, I'm sorry I thought this was the SRT site. Not really it's just fun to show off the car
I had a Limited coupe and I am quite sure it was considerably better than 7 seconds.
Regarding the weight difference 100lbs does strange things to excelleration.
It's like me being about 250 pounds sometimes I wish I could find a 140 pound "driver" to see what type of numbers my car COULD post.

Let me know when and where, although, I am more like 155

 

Thanks for the offer, will do if the opportunity rises.
Indiana is a fair jaunt from Montana. Heck it seems that everywhere is.

PS I couldn't couldn't keep from spinnin them a bit but turned another 4.07 with my wife on board yesterday.
Never misunderstand me I am not knocking my 4.07 ! Matter of fact as far as street cars go I brag a bit!!!

 

I bought one of those K.A.T. Matrix 3-Axis Accelerometer - kinda a cheap version of the G-Tech. I have a '05 roadster with a sprintbooster. not sure if that helps or not but this is what the K.A.T. gave me:
1/4 mile:
97 mph
14.87 second
135 hp
154 hp

0-60:
6.34 second
141 hp
161 hp

 

Check out this "street car" - 4.53

YouTube - Eric Dillard 4.53@174 MPH!

 

what was his 0-60 time???? holy smokes that is a fast car....

 

Isn't the 0-60 also due to it shifting at ~55mph?

 

I went to the strip 100% stock and ran a 14.9 at 95mph and its the auto stick
