everyone keeps saying his setup sucks... ummmm what "setup"? Its a strapped on roots blower on a basically stock car. Its a 2.2 liter on 16psi. How do we know hes not running very conservative timing to avoid detonation on pump gas? Why dont we look at it like this... that motor makes what N/A... maybe 265-275whp tops? If 14.7 psi is considered atmospheric pressure, then 16psi should just above double his hp... however take into consideration losing hp for spinning the blower. Im sorry 530whp sounds fine to me. This isnt a shitty setup on a cobra.... this is a mental fast setup on a z06 that is substantially lighter with what sounds like a better driver. Z06 probably makes 420-430whp before the 150 shot. So say it makes 600whp...and is 600-700lbs lighter... yea... that vid looks right to me.
For comparison, a good friend of mine has a 2.2 KB on a terminator and his car made just over 600 on pump gas. His car runs door to door with my H/C/I C5Z

Had about the same luck in my 01 Z06, Same Cam (233/239), Ported 243's, 347ci and 3.91's with a Steig Stg 4 03 Cobra had 3.5-4 cars on him from a 20 roll to the top of 3rd (85-90mph).
Great kill!! Post track results as Ive been wanting to spray a 125-150 and this bottom end for awhile now.

Cobra Is on 16lbs light timing. I think 18-19 degrees on 93 pump for this Texas heat. Car has a return fuel system, 60lb injectors, Headers, JLT cold air, Straight axle, 3.73, and some cooling mods.
My Z06 has a Halltech, longtubes, Cutouts, Fast 90, LS2TB, Underdrive Pulley, McLeod Twin Disc, 90mm Plate system with a Standalone fuel cell on 109 and 150 Shot.
Before the cam I made over 400 NA.

Thanks. Went to SAR last night. Crappy prep on a weds. Drove my car there (200mi) ran a few NA passes and spun bad. Still managed a 11.69@121 with a 1.89 60ft on motor and made a bottle pass which was a real spinfest. 11.01@134.5 with a 1.96 60FT then drove home. I'll be participating in a track rental soon Enough which will bring new bests. I think I can squeeze a 11.3@122 and a 10.4-5@135ish
