MORE POWER

[Edgar.gonzalex]

I just got a 2012 genesis 5.0 and I want more power but there really no parts for the car . What can I do or should I do to get more of the car

Sell it and buy a CTSV?

But seriously, the car's torque peak is in a bit higher up in the revs than a typical Chevy small block. It drives more like a Mustang 5.0. So put the car into manual shift and keep the revs above 3k to get a bit more kick when you mat the long pedal.

Only 2 things I've seen that might get a bit more response outside a custom tune are:

- Change the air filters to K & N to lessen the airflow restriction.

- Remove one or more of the magnets from the flap in the main airbox to allow a easier opening for higher air flow.

Just stay away from "performance chips". But you can use a pedal commander (or similar) to change the throttle response. Does not give you more power, just changes how quickly the throttle body opens.

Or....... just enjoy the car as is. It is a beast. My car came with the filters already, I just removed a magnet from the flap. I've researched tune's, not cheap, and limited returns. If you want to explore them then check out www.10fintec.com . After I got the car last year I did all the research but after driving it for a while I was more than happy with it as it was.

I agree on enjoying it as is. Two reasons: 1) there isn't anything available that's any good, and 2) for a 2012 car, the Hyundai 5.0 engine is already incredibly efficient from a displacement point of view.

Chevy arguably has one of the best GDI smallblock V8s on the planet, and Hyundai had a 15% more efficient power delivery 4 years earlier.

You can see in these numbers why I made the comment about keeping the revs up in the Rspec ... the engine torque kicks in as you get higher up in the revs.

	Displacement (l)	Peak HP	hp / l	Peak torque ft-lbs	torque RPM
2012 Hyundai	5.0	420	84	376	5000
2016 Chevrolet	6.2	455	73	455	4400

Depending on the mileage, I would suggest 3 things. I bought mine with 54000 miles and it now has 125,000. It got slower with time. At about 110,000, I flushed coolant, replaced spark plugs (use OE only, NGK iridium) and had valves walnut blasted. Then had all necessary gaskets replaced. New lease on life. Faster than when I bought it. GDI engines get the valves gunked up with carbon, which hurts power and gas mileage. Walnut blasting gets the carbon off without damaging the metal. Have it done by someone who knows what they’re doing, a few pieces of walnut shell left behind will damage your cylinders and walls badly and ruin compression.

Did you get any pics of the valves and intake before an after ?

 

[GENNY429]

I did not. I should have. I can tell you they looked like crap when he started. Completely black and chunky stuff stuck to them. I would assume the air going through there was quite turbulent after hitting that stuff.

I like the chart but the 2012 5.0 was rated at 429. That’s only with premium fuel. Is that your chart says 420? Both on regular?

 

[Gunkk]

Ahhh right you are. Chevy #s are Premium 93, so yeah 429, even better supporting the point about top end performance of the DOHC power plant.
