Kind of a late start to a build thread, but with some trips to the dealer, a woman backing into me, and some parts decision changes, my car is back to having intake, cmd, and fmic kit as my only performance mods. While it won’t be as “OMG” as some of the big power build threads, I figure it should help those building on a budget, so to speak.
My overall goal for the car is to make it a blast to drive around town and still be able to control it at a track, for now I think 300/300 will do the trick. My initial power goals for the car were to hit ~250whp and similar or better torque. With that being pretty much accomplished with my first 2 mods, only 25whp short without any exhaust, I had to bump up the power goals a little bit. I’m hoping to pick up a membership at Harris Hill Road in San Marcos, Tx later this year or early next so I can finally get some actual track time with the car.
As far as looks go I think Hyundai did a pretty good job and I prefer more of the subtle aesthetic mods.
I've got a Seibon CF oem style hood going on and I should have a CF grille and fog surrounds coming soon too.
First performance mod I put on the car was the CP-E Intake. Overall I felt this was the best solution out despite the high cost. The fact that it’s 100% made in the USA is also worth a bit of extra dosh to me. I don't have a pic of just the Intake but the following should suffice.
I’d definitely suggest this intake <edit: after it rubbed paint and slightly dug into the frame on 2 of my coupes and many others I retract my suggestion> to anyone unless you plan on swapping turbos and not going with a full CP-E solution. If you do, you’ll need to make your own elbow to go from the turbo to the back of the box. It keeps the darth vader sounds to a minimum, keeps the heat away from the filter, and looks pretty slick under the hood. Overall impression of the intake is good and it definitely added a bit of power on the top end.
Next I decided a retune was in order. I picked up the Dynojet CMD and was immediately impressed with the performance on the GC. Even before hitting the dyno I knew some really good gains were made.
Getting the CMD setup and running was a pretty straight forward process. Install took about 20 minutes including installing the software and uploading a map. The base maps that are available do need slight adjustments though, mainly map and tip clamp values. Hooked up the laptop, went for a few WOT runs, updated the clamp values, and away I went. No CELs, no random shutdowns, no problems to speak of since install.
Using a 20psi peak tune I was able to put down 225whp and 270ft/lbs of torque, an increase of 40whp and 80ft/lbs on top of my “baseline” with the CP-E intake. That’s only $10 / WHP, pretty hard to argue with that IMO. Coming from driving N/A Hondas before, having 270ft/lbs of torque at 3000rpm is a blast!
Next up was the AGP catch can and breather. After putting the CP-E intake in and seeing the amount of oil in the factory intake and on the lip of the turbo, no way I was going to run without one.
Almost 8K miles later and not a drop of oil in the intake or on the lip of the turbo, makes me happy!
Next up I decided that a new FMIC was in order to help keep the air a bit cooler with the turbo working harder now. LoveFab was looking to get a new “crash bar friendly” core out so I did a little testing for them and got a killer deal on their FMIC kit. One thing I like about the kit is the short piping and only 4 couplers on the whole setup. The core should be good to 400whp so unless I change plans drastically, it should suffice for the long haul.
I hit up the dyno after getting the FMIC and quickly experienced the suckage of the stock injectors. The FMIC fattened up my power band a little down low and didn’t really lose any power anywhere in the powerband. With the stock injectors being maxed out and now running a little lean, I ended up having to drop boost back ~1psi across the board. I ended up with the same power on less boost though, so I was a happy camper.
After finishing up the basics on the intake side of things I moved on to the exhaust. At first I was dead set on a quad tip that was quiet but still performed. Found a good deal on the Agency Power cat back from Vivid Racing, so I ordered that and installed. The exhaust itself looks like a quality piece and had a nice quiet tone to it. Pretty much no droning on the highway at all, but a bit too quiet for me under WOT.
A little bit went by and after some more thinking I decided to go with a single exit exhaust instead. I picked up the Ultimate Racing single exit with resonator from another forum member. Exhaust has nice welds and sounded pretty good on his car, unfortunately I haven’t had the chance to install yet.
More to come...
