NOS!!! 2015 Hyundai Genesis 5.0L V8

[carguy75]

Never got around to it. still brand new in the box Let me think about how much I’m willing to lose on the deal LOL

LOL. I would not even mess with the NOS unless you are trying to win some pink slips in some illegal street racing.

The 5.0 V8 only needs a few mods like performance air filters, throttle body coolant bypass and a throttle booster to move quicker. The mods will not make 500hp, but the mods will allow the engine to run stronger and reduce throttle lag so it feels like a quicker car.

The 2015+ 5.0 engine can do 0-60 in less than 5 seconds(4.6-4.8 seconds) with just a couple mods and still be reliable; which is damn good for a car its size. No need to possibly kill the engine and transmission by going nuts with the power to get this boat any quicker.

I am still leery about long term reliability of the modded 3.3T G80/G70 models I am reading about. The transmission on those cars will probably be trash before 100k miles or just after if the owner has too much fun with the tune unless they meter how often they use the extra power on the street/dragstrip; which defeats the purpose if you got to baby the car with the tune for it to actually last just to say that it makes 500+ hp on a dyno; but tear itself apart if you actually use the extra power on a daily basics.

Mine is at 4700lbs this bbtch is HEAVY . But like you said, still does 0-60 in 5 sec flat and 1/4 mile in 13.9 until heat soak (Texas) starts turning it into 14-14.1/14.2
No complaints here
Unless it’s a Toyota or Honda I’m TERRIFIED of turbo reliability/ longevity
I do have k&n drop ins as removing stock air box and replacing with “cold air intake” seems to drop a few horsies. Can you explain the throttle body coolant bypass power gain and what throttle booster is best in your opinion

Could you imagine if this car was 1000lbs lighter 🏎

The throttle body coolant bypass is just rerouting the hot coolant hoses that flows into the throttle body so that hot coolant does not increase the IAT tempature going into the throttle body. The mod is only good for maybe 5 hp at best based on results from other cars that have been dyno from other auto makers.

My IAT is about 20-40F degrees cooler without the hot coolant(200F+ degrees) warming up the throttle body. Do not sound like much, but cooler air does create more power; even if it is not much.

However, this not the mod to do in cooler states that have freezing temps since the hot coolant flowing through the throttle body is suppose to keep the throttle body from freezing over in the winter. My IAT never got into the freezing zone here in Georgia even when the temps dropped to about 20F, because the engine bay heat still keeps the IAT about 20-30F over ambient air temps.

My IAT temps in the winter at 40F with the coolant bypass. The IAT was still about 80F due to heat soak from the engine bay. Before the bypass the intake temps was about +100F even in the winter.

Currently 76F outside and my IAT is 158F so def interested in doing this

Sounds about how hot my intake temps was before the bypass.

My engine seems to like the cooler airflow; so I think the mod is worth it even if it does not free up 20+hp or even 10hp. The engine seems more responsive, but this is only my perception that has not been really tested.

It a free mod so who cares.

Never got around to it. still brand new in the box Let me think about how much I’m willing to lose on the deal LOL

Lmk man I’ll take it off your hands got a 2013 been wanting to do that
