When the car was still running an M6, I checked an 11.5-sec pass once, using the data log from my MoTeC (time vs. eng rpm every 0.04 seconds), and it was approx 3.2-seconds. That assumes there was little tire growth up to 60mph.

I used that calculator that MARZ posted above, and it put me at 3.9 on an 11.9 pass.

On a 11.5 pass it puts you as 3.6.

Interesting to see all the different calculators and all the different values we all get.

Ok.. and mine dynos at or near 320.. on your average Z06 (lets say 350) thats 30 rwhp difference.. Not too much difference there.. I wouldnt say their tires are all that great... My car weighs in at 3430 with a full tank of gas and everything it usually has in it (spare and all).. What does a Z06 weight? 3200? Again not a huge difference..

I wouldnt go discounting all the stock Fbods out there.. some are pretty strong..

Depending on options the z06 can be as low weight as 3110. As they should be, the tires on the 04 zo6 are much better then what came stock on our cars. The stock gear ratios are :

Camaro
Type 6-Speed Manual
Final Drive 3.42:1
1st Gear Ratio 2.66:1
2nd Gear Ratio 1.78:1
3rd Gear Ratio 1.30:1
4th Gear Ratio 1.00:1
5th Gear Ratio 0.74:1
6th Gear Ratio 0.50:1

The corvette z06
Type 6-Speed Manual
Final Drive 3.42:1
1st Gear Ratio 2.98:1
2nd Gear Ratio 2.07:1
3rd Gear Ratio 1.43:1
4th Gear Ratio 1.00:1
5th Gear Ratio 0.84:1
6th Gear Ratio 0.56:1

It should be quicker off the line and produce a much lower 0 to 60.

If you use that calculator (enaf1) for the range of 13.0-15.5 second 1/4-miles, you get a difference between 0-60mph and 1/4-mile time of 8.4 to 8.5-seconds. I think that's what I said up front.... except I extended it to 12.5 seconds, and I am still within less than 2/10ths at 12.5-seconds

If I use the "teamnabr" calculator linked in the "long thread" posted above, which uses 1/8-mile ET and MPH, my 11.5@117 gets entered as 7.45@93, and the resulting 0-60mph is 3.1-seconds, vs. my actual measurement of 3.2-seconds. Sounds reliable.

I also found a timeslip with a 7.18@98.4 1/8-mile (11.16@128) and that one yielded a 2.67-sec 0-60 time on the calculator. I never calculated that pass from the data log, since the huge amount of slip in my convertor means I can't work from engine RPM to MPH like I could with the M6.

If I take the data directly off George's time slip from a 8.76@160mph pass (5.70@128mph in the 1/8-mile), it calculates his 0-60mph time as 1.25-seconds.

Not bad for a 3,535# 30th SS Convertible.
