hi all - i went to a track rental weds at atco, NJ.
first time dragging the zl1.
2013 M6 Zl1
3955 lbs (no driver) with pass seat removed and lighter weight wheels/tires.
1/4 tank of gas. Torco additive.
MT ET Street 305/45/18 25 psi and 255/18 goodyear RSA's. (these wheels were from my firebird, and the whole wheels/tires setup saved 75 lbs).
The only mod is rotofab CAI.
Probably making about 525 hp at wheels. I did dyno once and it was 507 but there was KR and it was only making 19 degrees timing; i think due to winter gas.
