A dual CAI, same pulley and re-tune 60' was 1.8, 1/8 was 8.0, at 87mph, 1/4 was 12.43 at 111.6 mph.... and the times keep coming down the more you mod...I have since added new intake mani's and few other tweaks to get the roadster to the 12 flat area...the coupe is getting even more mods to break into the 11's...
