3.3TT Mishimoto's Stinger GT Intercooler Kit R&D Thread

[ZyroXZ2]

The G70 crash bar, behind the front bumper, is aluminium instead of metal. The Stinger has the metal one.
The mod is popular in Korea and it is mostly done to reduce the weight on the front of the Stinger.
How much weight? Don't know.

Supposedly around 15 lbs difference, which is quite significant at the nose and also a reasonable expectation going from steel to aluminum as I've looked at the crash bar and how to remove it (which is also easy).

(pssst, aluminum is also "metal")

What's the weight distribution of the stinger stock and how does this change it? Would be a cool mod if it does actually save 15lbs off the front axle but I worry about how it affects a front crash? An AWD GT2 is like 200lbs heavier than the heaviest G70..

51.9 front 48.1 rear according to road and track but they also post a curb weight of 4004-4157

It's officially 52/48, but that weight split changes if you add weight to the back.

Also, it's not so much weight over the axle (even though its weight is applied vertically that way if you weighed the vehicle), it's that it's at the nose of the car in front of the front axle, which has repercussions pertaining to handling. This is why the G70, for all intents and purposes, handles and feels a bit quicker than the Stinger: it's lighter. I believe slalom courses also show the G70 handling slightly better by the numbers.

Weight is the nemesis of all cars

 

[zbc1969]

Doing the math I don't think it doesn't change the weight distribution enough to matter. 51.7% front instead of 51.9%. Still wonder about front impact though

Yeah that's what I meant. I should've said beyond the front axle. No doubt it would make the car handle better. The G70 also has a 3" shorter wheelbase and 6" shorter than the stinger overall. I feel like that would make more difference than the lighter crashbar

I didn't say swapping the crashbar would make the Stinger just as good as the G70, lol

It's about improving upon, and the reason the swap is being made in Korea is because they care about how a car handles more than 'Muricans tend to. Most people probably won't feel the difference, but I guarantee I will

I can tell you that when I was installing my JT intercooler, I removed the crash bar in order to make installation easier. Honestly I did not find it that heavy.

 

[Manaz]

On it's own, it won't be significant.

But 15lbs/7kgs at the front extreme of the car is more significant than 15lbs/7kgs directly over an axle, or between axles, because of the leverage it exerts and the location of the weight where momentum is concerned.

There is a common item in kids playgrounds where you stand on a small platform attached to a vertical pole, and the whole thing rotates about it's axis. If you've ever done the thing where you lean out as far from the centre as you can and start it spinning, and then pull yourself into the axis and speed up, then you've experienced this.

Angular momentum and conservation of energy have impacts on cars too - not just for turning, but even when considering suspension movement.

Thanks! Things were getting a little out of hand, and we really appreciate you putting us back on topic! Also greatly appreciate everyone's understanding of the process!




Just out of curiosity, how popular is the G70 crash beeam mod? Also, we would love to test fit on a G70 as well, so if you know anyone in the Delaware area with one

You're not actually far off. We still have at least a few weeks before we have a testable kit here. After the testing is finished up we'll still have a few months before we can launch anything, but I'll make sure to keep you in the loop!



Definitely check out the link that @Manaz posted below! There's a ton of info in there about the different aspects of intercooler construction that effect the cooling, power and flow.

Two directly answer the question though, it won't matter very much. Intercooler design is a delicate balancing act between to create a heat exchanger that can flow but also quickly dissipate the heat. We'll be using a bar-and-plate core which is much more effective at both of those than a tube-and-fin design. On top of that, we wanted to make sure that all of our fin surface area was being used. Sure we could have gone bigger, but that would also have an effect on pressure drop, and anything tucked behind the crash beam wouldn't be very effective at transferring heat.

We also have our own technical article on intercooler design and construction if you wanted to dive in there too





We're looking at a 28"x8"x4.5" core and it'll easily support up to 800hp. Pipes come in at 3" as well



Thanks for the link! Definitely a lot of useful info in there guys!




We're planning on this being the best bang for your buck kit, and we'll have a discounted presale AND offer financing as well, so plenty of options for you! Also for the BOVs, our hot side piping will still be compatible with the stock re-circulation valves, so as long as your adapter plate works with that you should be OK. We also may be working up an adapter plate of our own, so stay tuned!


Thanks for all the questions guys! Keep 'em coming

So where would one buy this Aluminum crash bar?

 

[Manaz]

So where would one buy this Aluminum crash bar?

Either from Genesis direct, or one of the third-party OEM part suppliers - someone like Partsouq.

It is part number 64900G9100 and showing as discontinued on most sites. Not sure what is going on.

Any new news or release dates on this intercooler? I’m shooting for 10.90’s in the 1/4 by Christmas and I’m hoping the Mishimoto intercooler can be part of the equation.

 

[Toddasaurus]

Let's go, Mishimoto!

 

[xot1]

If the core size is 28" x 8" x 4.5" as advertised, it should be the 2nd largest intercooler the market.
If other features are good (including price) it will make an interesting offering.

Anyone know anything about BMS's FMIC project?

Edit: my bad - somehow missed the first line - thought it was sorted by size and looked for stock near the bottom

It is sorted by core volume except stock.

Hey Guys,

I know it's been a minute since we've had any updates, and we still have a few weeks before we have a testable sample in the shop here in DE...

BUT, I wanted to give you guys the first look at our intercooler kit brought to you by our drafter's rendering skills:

More to come soon! I'll make sure to give you guys the first look once we get our samples in!

Feel free to shoot me any questions you might have!

A lot of us are looking to implement the BMS CPI solution. Vote +1 for a bung option.
