Any one have any videos? Like to see 2 pdk cars, 1 modded and 1 not in a race to see real effect not just dyno charts. I chose pdk because i have a pdk and because its a cleaner race (basically takes the driver out - just mash the gas pedal)

i modded my 997 S - Suncoast headers, EVO intake, GIAC flash, pse. didnt notice any power gains and either did the dyno!

I wont mod my 997.2 S without real proof.

 

Did you dyno test each part or the collective? I hate to say it, but you were likely making power with some of those parts, and losing power/torque with others.

 

P997s...let's do a drag race! Desoto Raceway does a run what ya brung. My 2012 GTS has the factory power kit and I put on a cat back free flow exhaust. Would be fun!

 

Unless you did the cats you won't get much. Run it at a drag strip w and w/o mods
