Mark's 1970 Corvette
Time Slips

Unfortunately, I haven't had the opportunity to take my car to the track.  The closest strip is Moroso Motorsports Park in Palm Beach Gardens, FL which is about 2 hours away from my home.  The plan is to run the car sometime this winter (late '01 - early '02).  I will post the timeslips then.  

In the meantime, I've run a simulation with Drag2000 V3.05 using my vehicle specs and a Dyno 2000 engine simulation results.

Drag2000 Parameters 

Note:  Times are drastically effected by the traction coefficient and driving style.  I used a 1.4 coefficient which is the mid point of the range (1.1-1.6) suggested by Motion Software for high performance street tires.  For driving style, I chose the default "Aggressive" parameters which are in between the "Professional" and "Conservative" styles.    

Results

Comment: As you can see below, the 60ft time suffers (2.16) since significant tire spin in the first 25-30ft (2.5-1 tire speed to mph ratio) was factored in.

Changing the traction coefficient to 1.6 factors in much less spin thereby reducing the 60ft time to 1.88 and the 1/4 mile time to 11.89.
