Accelerometer

[Patton]

I have a Beltronics Vector FX2 and I want to see how much hp my ZR-1 puts out without the secondaries working ( ) so I was wondering if any of you guys know the following;
1. Coefficient of drag
2. Frontal Area
3. Also nobody seems to agree on this things curb weight but from what I have read I am guessing 3500lbs.
4. This last one is less well known than the others, what percentage of horsepower at the crank is lost through the rest of the drivetrain. I guess basically I wondering how much actual RWHP the car has, I could do the math from there.

Thanks killers!
