Tuning a Genesis R-Spec

[Crusty Old Shellback]

Hyundai already has a supercharged 5.0 in their factory. But we will probably never see it.

But yes, tunning is the major hold up right now on doing any mods with good results.

With a good fab guy getting a supercharger to work with motor is the lease of your worries. Headers, exhaust...are in the same boat. Getting engine internals are also easy. My 12' 5.0 is stock because of the ECU. Once the ECU problem is taken care of the rest will fall into place!

Engine internals are far from easy. Anything you order would have to be custom made. It's only easy if you throw your bank account password at someone else to handle it.

It was a 4.6L and it is not a setup that was ever meant to be sold. The supercharger was done for show and the cylinder de-activation on its engine was a testing bed.

The 4.6L and 5.0l are the same motor, just a bigger bore and DI on the 5.0.

And yes I know we will never see it from them. Or will we?

Well overall you have a point, I guess I'm used to the "custom" price due because of my Impala.

Another reason there is not any tuning for the v8's is that they weren't offered in Korea which is where all the tuning started for the 2.0's and 3.8's in the coupes. If you notice the OP stated he is wanting to get the 2015 genesis which I believe is supposed to have a TT 3.3L. I can gaurentee that tgere will be aftermarket support for it, as it will have a ton of potential.

DRS - again, completely inaccurate. Not sure where you are getting the info from. You should cite your sources instead of blasting the forum with bad info.

BTW the Hyundai 5.0 liter is a GDI (direct-injected) which is how it produces about 20 more HP with the same displacement. And it costs a lot less to reverse engineer an engine than it does to develop it in-house, which is what Hyundai did.

"About 100 engineers were involved in the clean-sheet design, which took 48 months to develop at a cost of 260 billion won, according to Hyundai."

Two Ford Engineers that also are winding down the GT500 program (for now) are part of the source pool. They are impressed with the TAU, see the similarities and differences. The 4.6 and 5.0 may be a "clean sheet" just like Hyundai said their early Toyota designs were "clean sheet". Look, it does not matter. Ford has a great engine platform that has been licensed (Mercedes, back in 90s forward, and promoted on a Ford commercial with Germans running around the Ford engine plant on a golf cart), and used as a template by others (Jag, LR, Volvo V6, Mazda 4/V6).

The 5.0 Ford by design (no head change, open up heads to add DI) can handle either DI or port. As spoken by the engineers I stay in touch with (Old SCCA contacts). Back then they chose to use port injection because of the intake valves getting deposits with DI and a slight issue with PCV oil coming into the intake. Which they do not have an issue with the truck 5.4, 6.2, or the older 4.6. That issue is fixed now... Expect to see DI on Ford V8 platform, with a CPU mapping that does not run rich to prevent knocking like the 5.0 TAU does.

The TAU 5.0 is amazing.. Nothing smoother on acceleration, idle since the early 4.6 SOHC Fords with aluminum intakes (later went to Montaplast plastic intakes, which in addition to the head redesign made the 4.6 less smooth and quiet. Of course the TAU does GLH compared to any of those.

Anyway, some day there will be enough volume of these engines to redo the ECU mappings, and possible place a Supercharger on top (if it would not add any height). Uhmmm, maybe I will check in with Kenny Brown here in town and see if he has any interest in tackling this for a Genny and Equis.

So we went from accusing Hyundai of copying Ford engine design to stealing design language from Toyota? All I was pointing out is that Hyundai didn't get the design from Ford's coyote motor.

I too am looking for suggestions to modify my Gen 5.0 R-Spec...So far I have changed Exhaust...Magnaflow X-Pipe....Rear Cat Deletes....Removed Resonators....Custom CAI...That's all I can see that's possibly available....Any input from anybody would be greatly appreciated....

Unless someone wants to be catapulted back to the stone age, there is no such thing as a "clean sheet" design. The whole point of technological advancement is to build on the past, and hopefully go forward.

You're going to be building an engine that has no off-the-shelf performance parts and the same with the transmission.

Sorry I'm late to the conversation but Tjac357 there isnt a R spec in the new body style yet and I don't think there will be. The R spec sedan was produced from 2012-2014 and is still the fastest/ most powerful Hyundai ever made. The big news is of the supposed "N Line" of performance vehicles to come in the near future.

I agree with comments above that the 5.0 GDI Tau was made in house by Hyundai based off the 4.6 and is a award winning design.The motor is pretty much maxed out horsepower-wise but could benefit like someone said from trans/ESC tuning. Exhaust, Secondary cat deletes and Intake make a noticeable gain in performance. The ECU adjusts very well to these mods. I think anything more would stress the drive-train and engine internals. It outruns lighter sedans with matched hp numbers. Other weak points which I have addressed are the tires, the suspension and brakes. Its not a M5 but the car is a beast for what it is.

2013 5.0 R Spec with custom CAI, electronic cutouts, resonator-delete, X-pipe. The 5.0 is leaving some power on the shelf; it runs RICH and would benefit from a tune to lean out the air-fuel. Without a tune, bolt-on mods will give you a handful of HP (the stock mufflers add backpressure, as do the cats and resonator) but help with throttle response. A 12.5:1 DI engine should make AT LEAST 90hp/L on 91 Octane. The 5.0 makes 87. Agree with what has been posted: a lot is lost to the slow shifting transmission and torque converter that takes time to lock-up. (The ZF 8 speed could teach our transmission a thing or two.) Enjoy your car. There's not a better all-round 429hp luxury ride out there for the price.

As much as I am impressed by my 2013 BBB 5.0 R Spec, I feel like I have a caged beast that I can never let out to really see what it can do!

Pull out the air flap/door under you main air filter. Open the air box and take put the filter. See the door... ? Pull that piece up and out. Enjoy the new air flow.

This will help with response and you can do the same in front of the small air filter up front.

Ok I get the air flap/door but can you explain what needs to be done to the front of the small air filter. Thanks
