I know exactly what you mean!!!

 

in any case i think you should ask you tuner who will be doing the installation. different cams are recommended depending on the overall combination and results you are loking to achieve. i would not start playing with cams unless you have a specific goal in mind.

 

im amazed about how much bad experience and history with 9ff thanks for sharing .. `

 

997 tt stock cams are not so bad so there is no much space for improvement or you want to
At first we should find the source for the sport cams......

 

it's a long time but, I can show the dyno graph with new cams

 

really nice .. so what kind of cams you used ??

 

I have higher lift in combination with springs and longer duration of course....

 

What turbos you use to reach that power ?

 

how much more lift & Duration?

 

please noticed that this is european power.
turbos are gt3071r
intake is 1mm higher and duration is over 270 I guess

 

Hi karol..this is nice power...is that power in DIN?....in what boost you have this power?with stock internal?

 

Hi

boost curve you have on the graph.
max power is on 1 bar boost.
this is maha dyno, so no idea, but this is real power.

 

As usual pethatic performance

 

Is the drop off at 6600RPM typical for an engine dyno?

 

Is this a factory engine? Or does it have stronger Rods, Pistons?
