More Power?

[twelvexes]

I drive a 2019 GT making 425whp and 503wtq with these mods - dyno tune for 93 octane, JB4 tune for WMI, intake, exhaust, intercooler, WMI, downpipes and plugs. Looking to make more power and not sure what the next best mod would be? Any suggestions? Thx!

Do you have secondary downpipes or both the primary & secondary downpipes installed?

just secondary.

i'm also interested in possibly running e85, but i'm not exactly sure what all is involved with that regarding parts needed, tuning, etc.?

Got it, the reason I asked is because secondary downpipe’s net approximately 12-14hp if that.

The Ultimate Performance HFC Downpipe + Mid Pipe Combo Kit makes 46whp & 62wtq on a stock Stinger 3.3T.

We always encourage customers to avoid going with just the secondary and instead going with the primary and secondary downpipe together to gain the most Performance out of their Stinger. I’d recommend swapping the secondaries out for the combo kit to make an additional 30+hp.

To each there own. But 425hp at the wheels is pretty good in my book. These engines in the all wheel drive config are pushing

a lot of weight around and in my opinion that is a really good number. I have thought about modding, but I just do not feel

that the car can handle a ton of modding as the head bolts tend to fail. Good Luck!

Supposedly Tork has figured out a solution to this issue. Hyundai and KIA 3.3TT Catless Oil Burning Fix
I'm waiting to see some feedback from the few that have pulled the trigger on it. My biggest issue is there isn't a ton of data other than "trust me bro" words being shared.

Since this was posted in the context of this downpipe discussion, I’d like to respond with some details for clarity.

The issue you're referring to, increased oil consumption or burning, is typically associated with catless primary downpipes. The setup we are referencing here is a high-flow catted system, which includes properly engineered catalytic converters designed to maintain performance gains without the common issues tied to catless options.

We have sold just over 200 of these Ultimate Performance HFC Downpipe and Mid Pipe Combo Kits over the past 6 to 7 years, and I cannot recall a single customer reporting oil burning or related issues to us after installing these. The product has consistently received positive feedback, including over 34 five-star reviews on our site.

Always happy to help clarify where we can, and we are here if anyone has more questions about setup, compatibility, or performance gains.

Hey Sal and just to clarify from my 2yr's of spending money on this car based on forum recommendations, I had 200cell catted 3"downpipes and the oil burning started as soon as I removed the secondaries as well...

When I refitted the secondaries it almost disappeared, but there was still residual oil in the pipes so I bought a second hand set of tailpipes/ mufflers for accurately monitoring this over many months and once I finally refitted the factory primary cats including secondary cats, the oil in my tailpipes disappeared completely.

Only 116mph at the track proves the factory system kills power and how much we need a product like this and the smile it puts on your face !!

I am still waiting for the apparent fix to arrive from Tork and then I will refit the hi flow cats and try again.

No smoke and mirrors here mate, just transparency.

I ordered that from John a week before I ordered parts from BMS and I already have the BMS parts on my vehicle... *sigh*

Thanks for sharing your experience! Just to clarify, I’m David from the @K8 Stinger Store, not Sal from the forum here.

I totally believe you experience these issues with your vehicle that you’re describing, but it might be because your car had some oil burning issues that weren’t as noticeable until the removal of the secondary downpipes. We’ve sold quite a few secondary downpipes and complete primary/midpipe combo kits, and haven't really seen this kind of issue pop up with our customers. Of course, every vehicle is different, and it's possible that something with yours was a bit more sensitive to those changes.

It’ll be interesting to see how the refitting of the hi-flow cats and the fix from Tork work out for you. Keep us posted on how things go.

Thanks will do... I just realised your dump pipes have 400cell primaries?

You're welcome, and yes, that's correct. These include 400-cell Magnaflow high-flow cats. I think that might be the key difference some people are experiencing when using 200-cell or less on the primaries.

why do my threads always get hijacked? totally kidding btw!

That's a good amount of power you putting down. You can do a BEF+ from KJT. His e30 tune is aprox 475 whp/556 tq. That's probably what I might end up doing. He did the headstuds for the bms project single turbo stinger that they are building which I am dying to see in person as i live pretty close to the shop.

I run jb4 map 3 with e30 and it's amazing, tons of power especially being awd. I have the fuel it sensor hooked up to jb4 and it's super nice. It makes it super easy to full up and see ethanol content and it communicates with jb4. I probably wouldn't run e30 guessing always without that fuel it sensor. I usually am around e28-e30 always.

Stock primaries with catless secondaries, catback, bms fmic (going to get the bms chargepipes too), k&n intakes. It probably will run better with his tune and bms tcu. That's all I'll end up doing likely to my car. But yeah that will give you a nice bump in power.
