Just intake and exhaust, NO software, any results?

Correct, the porsche software can always tell.Originally Posted by The Bogg
My understanding is that they can ALWAYS tell if the software has been changed even if it has been changed back. Granted, they have to go looking specifically for this, not just a routine check. But if you blow up your engine I think it's fair to assume they'll look at things veeeery closely to see what happened.
The only 'safe' flash/tune warranty wise is the Ruf conversion, it does not void your factory warranty, can be serviced at any porsche dealer and Ruf will warranty your engine for 2 yrs. (I once saw a Ruf conversion hooked up to the pwis software, "RUF" in gigantic letters was on the opening screen. They have always had a very close relationship with Porsche). Pretty damn good, I doubt other tuners would do that, of course it's costly.
I have nothing against evo flashes, in fact they were my second choice behind FVD. I'm just pointing out the facts for the OP regarding warranty, no flames.

Chris, When you say Ruf will warranty your engine for 2 yrs does that mean the factory warranty for your engine no longer applies (even though you may have time left on it) or will Ruf give you a 2 yr engine warranty even if you are beyond the factory warranty period. Are there any limitations to the Ruf engine warranty? TIA, DaveOriginally Posted by TT Surgeon

When you consider an intake, you need to look at temperature and flow. Like Gene said, flow is restricted by the twisted tubing that sites behind the engine bay. Intake temperatures, specifically, IATs hardly change with any engine bay CAIs based on my datalogging. If you are worried about temperatures, change your ICs.
Why do dynos show HP increases with CAI's then? Look at how the dyno is set up...with the rear hatch open, and fans blowing from the rear. This hardly simulates real driving environments.
My IATs dropped ZERO degrees with Fabspeed's CAI using stock intercoolers at idle and at WOT to about 125 mph at Road America. If you want to prevent your car from pulling timing when temperatures climb, invest in ICs, not a CAI. If you want better flow, change the intake piping to Protomotive's MAFless in-fender style intakes, or change the piping with TechArt or EVOMs wider diameter tubing.
+1 for bbywu and eclou for the remarkable steady stream of interesting and trust-worthy information. I *am* impressed.Originally Posted by bbywu
There is only 1 true cold air intake for the 997 or 996TT...it is the Protomotive style under fender well system. All other intakes are based on some modified theme of sucking air from within the engine bay.When you consider an intake, you need to look at temperature and flow.

it is obvious that every intake system releases flow...good to hear that Fabspeed did not make IAT higher than OEM...as a result of these factors,an intake adds hp...

What is funny is that is not the case when I tested it.. I did that back to back on my GT3.. I actually did it 4x to be positive.. Open and closed and it made more power with the Trunk closed believe it or not..Originally Posted by TTdude
I think what's obvious from bbywu's description is that if you have the hatch open and a large fan blowing air on your intake, you will see an increase in HP.

That's pretty interesting. More power closed...hmm. I am confused.Originally Posted by Mike@AwdMotorsports

On the GT3, the flat panel replacement has a larger surface area than the OEM element...at least that's what I remember from my friend's car. Doesn't explain what you are seeing. But the design is different from the velocity stacks on the turbo.

Ill test it on my turbo next we are on the dyno to see.. I just did all my runs with it closed from what i recall..Originally Posted by bbywu

I almost always find sealed air boxes make more power.. The same went for my M5.. When the trunk is open even with a fan blowing air across the filter it picks up more hot air then if sealed breathing thru the ducts.. I also put floor drier fan on my back window and of course picked up even more by simulating real world air pressure..
