Add Power and great sound and experience your Porsche’s true capabilities with the Dundon Power Package. Intentionally designed to bring big power with and distinct sound we all love, this kit is perfectly tailored to add more muscle, better sound, and increased performance to your specific GT car. D


+ 47LBFT AND +38WHP! We continue to develop and find power in the 991 NA GT Cars as we love the challenge of finding all the little things the accountants made the engineers back off on at the factory.


The 991.1/991.2 GT3RS was first up, then we did the 991.2 GT3 Touring, Now the 991.2 GT3 (tested a pdk, applies to manuals as well). Next will be the 991.1 GT3 (as soon as the customer can get his car out of his garage due to torn up driveway...).

Results from a 991.2 GT3 PDK car. *from our testing a manual reads about ~10whp higher as there is less parasitic losses in the manual trans than the PDK. We'll work on getting a Winged Manual car to test, anyone in the NW interested contact us!


Reran the numbers and 47lbft gains max and 38whp gains max with 475whp peak power!

By reducing the pressure losses in the intake and allowing a more "free flow" into the engine the engine makes power two ways. First less engine power is used overcoming the parasitic losses of the stock intake tract. And Second we're able to get more high pressure air to the intake valve to cram in more air into the cylinder. Both of these translate into more power and on a car that uses Ram air to it's advantage (scoops on the decklid), the gains are more than can be measured on a static dyno.
