okay, i know this been a topic before , but i can't find it on the search anymore. Well, i thinking of during this on the 03 C4S, and want to know if my car would be a little faster and feel different from stock. I read the evoms.com website, and they claim 10-25 for intake and 10-25 for Giac.. so probably an average of 20-25 hp for both.. right? what's your guys opinion on this. any help would be greatly appreciated. thanks.

 

You know...I've tried to get to the bottom of this very question only 100 times and I've gotten no "real" answers myself...just assumptions and BS "it feels faster" responses. What you (and I) are looking for is HARD DATA proven the "gains" to your car. Basically, a before and after dyno on the same day, on the same dyno. That will answer all questions of these mods. I haven't seen one before and after dyno chart by an OWNER of a 3.6L e-gas car who've done these mods yet (EVO doesn't count for obvious reasons, no pun intended)......in short, we can only speculate they do but don't know for sure. Please do a before and after dyno on your car for us if you purchase these mods....same dyno, same day.

This has been beat to death. YES YES YES it works and does produce the HP and performance improvements.

Why would I subject my car to a dyno so I can satisfy someone other than myself? You will notice a marked improvement.

 

FYI,

The GIAC chip and EVO V-Flow air induction will yield the following gains for a 3.6L 996: (information taken straight from our website)

EVO/GIAC Stage 1 Software Upgrade: We were able to increase power with the chip alone by 9 peak wheel HP and 6 peak wheel TQ. There is a max power gain of about 12 wheel HP and 12 wheel TQ at various different RPM ranges
EVO/GIAC Stage 2 Software / V-Flow Air Induction System : Power is significantly improved with the increased in intake air velocity through our new V-Flow air intake system. This combination yields 17 peak wheel HP and 11 peak wheel TQ. There is a max power gain of about 22 wheel HP and 18 wheel TQ at various different RPM ranges.

 

i am convinced, got to head to Sharkwerk!

 

Please do a before and after dyno on your car for us when you install these mods....same dyno, same day.

i don't know where to have dyno done. but i will try.

 

Tomorrow I'm flashing a couple of TT's so roll on by No racing!

 

Dan at Vivid Racing posted some before and after dynos both here and over on Rennlist. It's pretty clear that power was gained across the revband.

Guys, why is it so HARD to imagine that the 996 engine is restricted in order to meet US and world emissions and safety regulations. It's not rocket science to recognize that letting the car breath (intake and exhaust) easier and then remapping the ECU to account for said easier breathing and exhalation WILL improve performance. Now, is it significantly noticeable? That's a matter of personal perspective. But, I'm sure most of you don't know jack about flying planes and aerodynamics either and still manage to fly from point A to point B.

Let's use a simple example: Porsche raises the front bumper 10mm to meet US safety bumper height regulations. It really screws with the aerodynamic flow of air over the car and flushes some underneath the car where it creates that 'lightened' steering feeling. Lowering the car resolves this issue. So, here we have a cut and dried example of how a Porsche is not OPTIMAL out of the showroom.

And frankly, if you want further proof about intakes and exhausts, then ask yourself why the 997 x51 kit includes revised versions of each.

 

all of evoms products look very well built and quality and i am positive that they wouldn't be selling products that don't perform how they say. Now will you notice a big difference. well that depends it isn't like you are supercharging the car. but the dyno stats are there and prove that it idoes increase engine performance.

 

I'm sure it won't be hard to find a dyno in your area...just ask around or look it up...there're not hard to find (including AWD ones). It will show (in a real world case) just how much these products do (or don't)...and should be VERY interesting for yourself and everyone else to see.

Got an EVO intake and flash at Sharkwerks this past weekend. Awesome job done by Alex and James. My 3.4L non e-gas runs significantly faster. Would highly recommend it.

 

Heya Lord, thanks for the kind words and 'twas good to meet you... That wing looks neat on the cab. Really does!

 

Will the chip flash and intake void my warranty (04c4s with 15K miles)?

 

It's a grey area.. Some Porsche dealers actually sell/install the same EVO products we do whilst others will try to deny a warranty claim based on the very same thing. If they can prove that the mod was the cause of the failure they could deny your claim but the same is true for you. You have the same rights... What we offer is a "free" flash back to stock should the need arise to do so. The intake only takes half an hour to swap in an out anyways...
