Yeah it's pretty crazy, that car is running a stock mount location replacement Evo 10 turbo and a divided manifold for a true twin scroll setup I believe.
It makes the same or more amount of torque as most 1.8 cars around these forums that make 400+whp. And want to know what's insane? Still has 2.5" catback. He's switching to 3" soon and that should help the top end because right now the HP curve hits a wall and flatlines at 5800rpm. So about 380WHP from 5800 to 7100. Torque peak is 380ft-lbs at 4500-ish.
He's a solid driver. I think the first time he drove a racecar on track was in 2014 at just 13 years old. It was actually my car that he was driving and I was in the right seat instructing for the weekend.

Looking at results from the last two years of GTA at Road Atlanta... several Corvettes attended in various classes. Only one made it on a podium (2nd place).

I think we’ll need the QBE90G for the next attempt. At that point lots of engines can fit, but we know there is a lot more in a TSE 7163 EFR BP and a BP poweredplant is way better for our brand and the Miata erase. Maybe not the 700-1000 whp range that other top Unlimited cars are running, but we can build a much lighter version of Vegas in OGK to bump that P:W ratio.

In theory, maybe.
But v8 swapped Exocets weigh what my ST5 car weighs(few hundred pounds lighter than Vegas), and only go a second or two faster than Spec Miatas.
V8 swapped cars require every other system of the car to also get heavier.
It would be easier and more worthwhile to put Vegas' drivetrain into OGK, resulting in a total package that is probably 400lbs lighter. Upgrade to a 3d splitter and make the two tweaks we've already outlined to the engine package.
330/2250 Bullet 2017
419/2470 Vegas 2018
600/2100 OGK 19/20 theory
As an aside, we should all look to Formula D cars for some stateside inspiration. Tube front, tube rear, pretty similar "production unibody" remnants must remain. 1000whp is normal. Pretty sure the top 10 FD cars would port into Limited class and be on the podium.

However if that 19/20 setup could be possible, and you guys have time to dial it in, I can see that being disgustingly fast.
P.S. Make a SuperMiata splitter/air dam kit

No doubt LS swaps weigh less than a lot of people think (mine was 2114 before the cage and some other stuff, I'm guessing between 2200-2300 now with cage but no aero), but there still is a trickle down effect on the drivetrain components of extra weight. But like Dan said, the LS miatas usually aren't as fast as you'd think. They're still lots of fun though
#237
Your skepticism is well founded.
I have not yet seen any in car video or data that conclusively shows an Exo going as fast as a Miata with equal equipment, let alone faster. Lots of ambiguous testimonials (and anger!). They're fun for sure, just not faster on a road course than a Miata with the same mods.
We spent several days on both track and street dialing in our Xida Race and XL with Sonny, data recording, pyrometers, suspension cams, careful kinematic and chassis measurements. IOW, not a peanut gallery guess but an opinion based on direct personal experience and significant data collection.
I'm sure this will get me some hate mail. To that I say, show me proof otherwise and I'll change my opinion.
