<SFR> SFR TUNED 3.8 V6 TwinTurbo AUTOMATIC! - Genesis Forum: GenCoupe Hyundai Genesis Forums

**Jay@SFR** · 02-19-2012, 05:06 PM

Ended up with about 384rwhp 351tq/lbs in hot and humid Philippines weather.

Yes, It's AUTO tranny... Didn't really like the way the car is setup that all the pipings (intake/intercooler) were in Stainless steel for some reason absorbing all heats from the engine bay and yet possibly melting all other components in the engine bay lol.
Though with the heatsoak issues, we were able to manage to make a great numbers out of it.

The owner/the shop could not figure out the way to tune the car for at least 6months after using all kinds of piggybacks that car wouldn't go pass 3.5k RPM.
Made the car in running condition in an hour and managed to tune the whole car within 5 dyno pulls.

Also I have confirmed that Auto tranny starts to slip after about 360tq/lbs without much load on the dyno meaning on the street it will have more stress.

More vids and details coming soon on our next video for full vid of visit.

**Jay@SFR** · 02-20-2012, 02:08 PM

Any pics of this said setup? You have me chuckling at that description. Must see it :-)

I need to beef up my transmission then!

danielskshin · 02-20-2012, 06:30 PM

I really thought that the ZF tranny would be able to take more of a beating then the trans on the 2.0 5 speed A/T. That really changes my mind about staying with the 3.8 Auto if I trade the 2.0 in for the simple fact I want more like 400 to 450WHP range! Hey Jay I know its a little off subject but I do not know anywhere else to post it? Can you guys tune on the new 2.0T KIA Optima the wife has one and I saw on the YouTube channel you tunning on the Forte Koupe did not know if you could tune on the Optima as well?!

**Jay@SFR** · 02-20-2012, 09:14 PM

Pictures will be up soon.

^2.0T Mirabeau, is it 2.0T or just reg one?

**Mira2White** · 02-20-2012, 09:17 PM

Its the 2.0T 2012 model.

**Jay@SFR** · 02-20-2012, 09:22 PM

Like I mentioned on the other vid, I don't like the whole set up at all yet the owner was very brave enough to do all the setup done.
The shop did a great work on the fabrications and putting all the components without major relocations like we did to our demo car.
What they forgot or try to get away to do (obviously never had experienced with Genesis coupe V6 TT work) is dealing with heat issues..
I've already told the owner if he uses the car to do WOT few times, the whole car will set on fire as is.

I've already corrected the owner to redo many things prior to my visit but still it needs a lot of heat shielding to do since now the car is in running conditions making power.
There are some secrets that I do not want to just give out online but there are common issues when you are putting FI on Lambda V6 like things I've given to Turbokits.com when we worked together on their kits.

Here are some pix.

No unfortunately NOT YET.
Even if we can, it's just plain dumb to advertise it online. Cant say no more.

AKGC · 02-21-2012, 03:48 PM

curious to know if you tell if there was any slipping, since the ZF torque converter doesn't have a wet clutch (lock-up torque converter).

**Jay@SFR** · 02-21-2012, 04:33 PM

Simple... We saw the slipping on the dyno graph.

**Jay@SFR** · 02-21-2012, 04:40 PM

^ Also forgot to add.. whole slipping thing will only happen when the car is really putting down the power to the ground.
I've mentioned this few times on other boards but there is a "torque management system" that is built in the stock ECU.
If that is not properly disabled or beefed up to the limit, car will only make power on the dyno and will not put down that power to the ground (or the dynos with loads).

This particular dyno that we've used in Philippines was an old school Dynojet that has big ass roller that has loads already.
Some might claim ZF can take more than that but that's when they don't know about whole torque management system or no idea how to play with it.
Same deal with NA tune..If Toque management isn't disabled or beefed up you will not see much gains on the dynos with any loads

(V6 only) sure worse on the street.

**Mira2White** · 02-21-2012, 05:50 PM

Very good info Jay thanks for explaining it in full detail I was curious on how the Transmission Unit would affect the whole WHP!

WhiteGenCoupe74 · 02-21-2012, 08:22 PM

cant wait to get a tune at sfr
