I put down 259 hp, 250 lb/tq (pics of the printout are in my gallery). That was with the GMTU and the Hahn DP + exhaust only. I need to see what it's putting down now with the IC and K&N filter. Mine is an auto BTW.

Later

I need to get mine to the dyno. my best 1/4mi was 13.55@107 stock with my own hp tune. just installed a crazysteve ic(which sucked bad, had to notch my bumper support ALOT) dejon ic piping(hot and cold) already had a k&n drop in, dejon 3" catless downpipe, and a torque monster trifecta+hp tuners tune by a badass local tuner that has been tunin for years(he helped zzp dial in their car before they ran the 11.6 run) let's just say that the rpd is peggin out at 25.5psi and my clutch is probally not holding 100% but its not slipping badly. it pretty much holds it in 1-4, havnt thought about going wot in 5th. sorry for the rant!

btw, dyno drags are usually about .9 off of your real drag time, I never ran better than a 13.0 in my 96 cobra on 315/35/17 bfg drag radials, but on cheap 245/45/17 all seasons I ran a 12.22@108 on a dyno lol.

i'm going to putting my HHR SS on a local dyno soon, i want to know what it's putting down before i do a custom tune. it's already really fun to drive and feels faster than my old Cobalt SS/SC which ran a 13.7 @ 105.
