Drag2003 evaluation
I found a $40 off e-coupon for Drag 2003, which along with my "preveiously regsitered" status from Dyno 2000 got the cost down to 50 bucks, so I bought a copy. It came last night and I played around with it a bit.
Somewhat to my surprise it gives the same numbers +/- a tenth as the free Race406 program I have does. It is nice in that it will read my dyno2000 engine data directly, but even though the "computed" HP is different in Race406 which builds it's own estimate from inputting engine data, the two program's et's are very close.
For my combo at least, the only thing that makes any significant difference is what you choose for the tire traction coefficient. In both programs you select a tire type (street, slick, etc) and size. Race406 must use a tire traction coefficient internally, but it doesn't tell you what it is. Drag2003 does tell you what it is using for each tire type. In Race406 you also select a chassis/suspension traction factor (if there is anything for the chassis/suspension type in Drag2003 it is buried and not accessible).
The Drag2003 user manual says it uses the tire traction coefficient for calculations, and only uses the tire size data for computing rotational losses etc. So, according to their manual (and my playing agrees) there is no "computed" difference with tire width (duh?). You can have it compute an "optimum" traction coefficient for your car, but since you have no way of matching a tire to it, it is only marginally usefull information.
The graphics in Drag2003 are cute, but the data table is more usefull, and does give some more data than Race406, like time in each gear. The shift and launch point optimization in Drag2003 works ok, but doesn't tell you much that would not be obvious to a semi-experienced racer. The gear ratio optimization is in my mind useless, as it changes the rear gear and all the trans ratios at the same time. If you could hold one constant and optimize the other it would be a lot more usefull. A very quick "hand optimiztion" will tell you the difference for rear ratios, which wasn't very much.
Conclusions? It's a nice toy to play with, but you'll probably grow out of it much faster than their Dyno2000 program. For the money (free) Race406 does just a well.
What does it estimate for Project No Flight? Numbers run from 10.1 if I could find the mythical perfect traction coefficient tire (actually most good slicks would probably be sufficient) to 10.3 for "high performance street tires" and 10.5 for "street tires". Now if I only knew what traction coefficient to assign to my 15.50 Hoosier radials I would have actually learned something.

Re: Drag2003 evaluation (GregP)
Greg, thanks for the link.
I have a lot of work to do to put my stuff in there. Took a quick shot at it and found it was off by half a second. I have to get more specific but thanks for the toy. :thumbs:
