2017 Grand Sport: Need Ways to Add 50-75HP?
I have a new 2017 GS. I was looking for an additional 50-75 HP. Starting w the easiest and cheapest ways to the more involved and exspensive ways? I'm not looking to race or drag it. I'm just wanting to add some more power. Thanks for any information.

Cam/ catted headers/ intake/ ported intake manifold possibly/ tune should make you very happy for about $5K.

Modding is fun but at least get a few miles on it to catch any immediate problems before you kill your warranty. The powertrain on this generation is more sophisticated than ever and failures aren't unheard of. Any significant changes (other than things like a different air filter which won't net much if any power gain) are going to kill the powertrain warranty. It isn't like the "old days" when a dealer could overlook things; the "bean counters" are serious about warranty costs and any major powertrain issue requires the dealership to do several specific checks prior to repair unless the dealership wants to "eat" the costs of repair.

Wow, a little sensitive I see. Lol. Since I've became a member of this site I've gotten some great information from other people and even given some myself. I cant find anyplace where I "flaunted" anything about my car. Maybe next time just don't bother replying to anything I post. I'd rather deal with positive people who aren't so sensitive or so quick to try and critique others. Thanks for the spoonfed info.

Don't listen to the haters. This is a great forum for information and there are a lot of helpful people here. With that being said, It's your car and as long as your happy. I had a base C6 that I installed a CAM, LTH, Tune. Afterwards, it dyno'd at 490 hp to the wheels. Of course I ended up blowing up my transmission and had to pay for rebuild since my warranty was voided. Whatever you do, make sure you have a good shop do it and don't forget about other components that need improvement when you start increasing power.

Have a look at the results from our stage 2 cam, intake and headers. This was a 100rwhp gain and still drive stock.

Cause its detuned from the factory and has a significant hesitation in throttle response. Combine that with some good factory tires and a car that handles like it's on rails and your left with owners wanting more.

I would start with what your goals are with the car. Think about how long you plan to keep the car and what do you see in 3-6 months or even a year down the road. I've wasted so much money in 20 years pulling stuff off to replace with another piece. Meaning, don't buy a intake manifold if you plan to throw a twin screw SC on in a few months. Don't buy Long Tubes if you plan on a turbo down the road. I know you said 50-75HP but that's the usual starting point. Nobody buys a C7 and wants to mod right from the start and never plan to do anything after that, lol. I remember when I was 21 I bought a 03 Mustang GT new. I told myself I would do a couple mods, tune, exhaust and be done with it. I ended up spending $25K for the next 5 or so years.
I've found that the fun mods make cars more enjoyable. Exhaust, shifter, tint, and some appearance mods. You know the mods you can see and feel daily. I'm a 80s baby and we went different routes first when we planned to race. I started with suspension/ tires/ proper rear end upgrades before adding anything to Torque/HP. Adjusting a factory alignment to your needs helps a car out alot. Whether it's caster to benefit in corner carving, track or changing camber. A freeway/drag type of alignment vs a factory do it all alignment. Can't have a perfect everything alignment. It's impossible. If you are in a environment where it gets cold in the winter get a set of Michelin A/S 3s. I drive my cars year round and make sure they are safe to do so. I don't get much snow but it will get into the 20s sometimes teens.
Other than what I said and everybody above. Think for a few weeks about what you really plan.

I have not put my car on the dyno before and after but I can deff feel the difference. I'm running ARH mids, Borla X pipe , HP tune, WeaponX ported TB and AFE CAI. I'm guessing I've added 50 hp and she runs good. My best 0-60 before mods on the street was 4.2. I can consistently run 3.9's now after all the mods. Good luck!
