510whp/600wtq! New Stinger stock turbo HP & TQ record?!?

[StungBlueGT2]

Kato just posted his Mustang dyno results on IG and think it qualifies as the new stock turbo HP & TQ record holder!@kato_the_kia_stinger on Instagram: “trip to the dyno. #jb4, stock exhaust, #WMI, #intake 442 WHP & 525 Torque. #dyno #dynotest #hp #whp #horsepower #torque #cargasm…”
Before everyone goes crazy, I know you can’t directly compare different dynos and this isn’t 100% accurate... However, a
442whp/525wtq MD is basically 510whp/600wtq on a Dynojet!

That’s using the typical 15% variances, but even using a conservative 12% difference(495whp/588wtq) Kato’s still 10whp & 83wtq more than the previous 485whp/505wtq record for stock turbos, and that car had FBOs!

The most impressive part is that Kato did it with completely stock exhaust & all 4 cats. He’s only running intakes and the JB4/WMI kit, which is the least amount of mods, for the most amount of power to date!

I have to say it’s amazing our Stingers can run about 500whp with just a few inexpensive plug-n-play bolt-ons. Who would have thought 150whp+ gains would be possible for only about $1k!?! Incredible.

Any attempt to calculate a difference between dyno readings on a Dynojet and an eddy current dyno, as in the above, is pointless. I know I'm new to the Stinger game, but those numbers sound high for the mods listed... Though I would not be against quoting them at the bar...

 

[Terry@BMS]

While MDs are great for tuning they are not consistent enough and too easily manipulated via correction factors and settings to allow for internet comparisons. Dynojets are the only machines consistent enough from one to the next to allow that sort of comparison.

In other words, these numbers are possibly inflated? Not intentionally of course. I can’t see it making that through stock exhaust. I’ve been wrong before. I will say my car feels radically different with just the jb4 on map1. Can’t wait for other parts to arrive

 

[Terry@BMS]

I make 460whp through the stock exhaust, and stock cats. I'm just saying dyno records are almost worthless as is and if you try to compare different dyno machines, it's totally impossible to get an apples to apples comparison.

 

[DarthVaderIX]

Help me understand @Terry@BMS what is the benefit of doing a free flowing exhaust if this is the case. In my experience it had tremendous benefit in turbo cars. The way it sounds is it is a 10whp difference if the car is set up properly on the stinger..am I wrong here?

That is quite backwards... hehehe

Understood and know there is no way to directly compare different dynos.

However, the consensus seems to be that Dynojets average about 15% higher and many people have confirmed those comparisons. Also one of our members with a JB4 ran 375whp on MD and others with same exact mods are running 420-430whp on Dynojets which matches the 15%.

Again I know its not 100% accurate but thought it was worth mentioning the JB4 WMI combo easily broke the current stock turbo record of 485whp/505wtq, and he did it with completely stock exhaust. Even if you use a very conservative 12% difference its still 10whp & 83wtq more than the previous record, so congrats Terry for making the two best bolts-ons available for our Stingers.

In my opinion: Exhaust/midpipes sounds benefit only. Primary cat delete probably worth 10-15whp.

You can make an MD dyno read whatever you want by adjusting it's correction/load factor. So any comparison based on a MD result is an exercise in futility.

Once the pure turbos and or bigger turbos start going on that will change right? Is it because the stock turbos are so tiny?

Free flowing exhaust does make significant gains and there are many dynos available showing improvements of each individual mod.

Most people gained about 10whp with muffler delete/axle-back exhaust, and 15whp with cat-backs. Catless midpipes/secondary DPs avg 20-30whp gains, and primary DPs 30whp+.

These are all documented individual gains so don’t expect to get 60whp+ with full turbo-back exhaust. But seems like most people get 30whp+ removing the bigger exhaust restrictions.

Luckily from Kato & Terry’s results the extra boost from a JB4 doesn’t make exhaust mods necessary and would just be icing on the cake, so to speak.

Lol. That’s ironic because one of your competitors says the same thing about the Dynojet you use... The TQ numbers are inflated and you must be manipulating the numbers in some way to your advantage.

I disagreed with them and don’t think you do that, just like I’m taking the MD technician’s word for it that 12-15% differences between dynos are pretty standard.

Unfortunately people claim any dyno can be manipulated, so people either choose to believe the results provided or do their best to discredit them.

Don’t get me wrong, I’m not saying to take the 510whp numbers as official results. I’m simply saying that based on MD techs knowledge and using the same mods on our Stingers on each dyno, 12-15% variance is the most common result.

So don’t be so humble and just accept the new UNOFFICIAL HP & TQ record!

Can't you also do that with a Dynojet?

You'd have to really go out of your way to manipulate dynojet numbers. But yes anything can be manipulated.

 

[RUFFSTUFF]

Maybe we should all agree that the data you get from a dyno can never be more accurate than the data that is input.

The Guys over at my vette shop used to play with the dyno jet and its readings....easy to manipulate the"weather station" and "other" dynamics ...but the all time faux horse power reading comes when one guy is at the very front of the vette's bumper down low with a nitrous bottle...and when the "run" starts he cranks open the nitrous tank....you wouldn't believe the nice HP and torque gain...seen it with my own eyes a couple of times....lol Wash
