performance analysis software * OMG dream come true

[c55m8o]

I stumbled upon this while researching what manual transmissions I could use (thinking of Tremec TKO or a Richmond). Visit here :
http://www.richmondgear.com/01cartest.html
and download Patrick Glenn's CarTest 4.5 for DOS .

It has =all= necessary parameters to analyze performance for our C-classes built right in!

One thing I did notice though, it doesn't account for driveline losses adequately. Example:

I took the defaults for the '98 C43, and it said the C43 was doing 0 - 60 in 5.5 seconds. ...no way.

I then realized, I didn't take into account driver's weight, + weight of junk in the car. Adding that, I got to 5.8 seconds 0 - 60. That makes more sense, but honestly, still too quick. Leading me to surmise it's over optimistic (under-estimating) driveline losses from the tranni, weight of the wheels, loss due to intake/exhaust restrictions, intake heat, whatever.

...HOWEVER, aside from that, which can be tweaked to dial-in an accurate baseline ... once tweaked this program provides an incredible VISUAL analysis of how altering things such as transmission ratios, power and torque curves, etc., affect performance.

YA! :banana:

You can't imagine how long and hard I've been looking for a program like this ... that's free ... and here it is! I'm so happy, I think I'll pick up CarTest2000 for $35.

all, I've been using this program -- the updated CarTest2000 that is -- the last few days, and all I can say is "wow". At $35, what a bargin.

Parameter Sensitivity Analysis is really, really kewl.
