So we do tons of supercharger installs on C7's but with the new 8 speed auto we really wanted to go turbo on one of our own cars. After we pestered CK at UPP long enough - we got one of their first kits !
Info on the car/mod list:
2016 C7 Corvette Stingray
8 Speed Auto
Custom Complete Street Performance VVT Camshaft
UPP Twin Turbo Kit - 5871 Turbos
Forged Pistons
LT4 Fuel Pump
Meth Injection
Mighty Mouse Catch Can
Speed Density Tuned with HPTuners
UPP's kit performs great and the turbos spool FAST.
With no further wait, a little montage.
A Little shift point tuning on the dyno. Very cool.
And finally a little blip on the street (in Mexico). You can hear the blow off valve go off before the speedo catches up to the actual speed!
You can see the manual boost controller in this picture however we have since switched to an electronic boost controller.
(We do not have the covers on in the picture however UPP does include their covers as well)
With the electronic boost controller a tap of a button either gives you tire roasting power or lets you dial things down so the car is a little more tame on the street.
Boost settings 1 and 2 do not use meth, so for those pesky times the meth tank goes empty you can still play and be safe. Boost settings 3-5 make a dramatic gain thanks to higher boost and meth injection. There is also a setting 6 that made 930 rwtq, but also found the limit to the stock rods. Basically the kit, even on the base turbos, is very very capable.
Starting in low boost and turning it up down the track (traction limited that night), we still managed to hit low 10's and trap 148mph
Currently, we are building a forged motor to turn it up a little more and go for the gold so stay tuned for more .

Ok so here is the million $$$$ question, so im about to do a procharger f1x kit, tell me a few reasons to do a turbo kit like this over a procharger f1-x ? Im going after 10000rwhp....go!

PROS:
Turbos, at the same boost level as a supercharger, make more power. This is because it takes direct engine power to spin the blower. As long as the setup is right, you should always make more power with turbos than a supercharger.
The turbocharger offers the ability to run at multiple boost levels. Meaning you don't always have to run at full tilt. As you see I have a friendly setting in the 5xx HP range, but then settings 200 hp over it and I can make that change with a flick of a switch in the car.
There is nothing like turbo spool up.
Ideal for an automatic because once you are in boost, you stay in it and at full boost. A centrifugal blower makes peak boost at redline and rule of thumb is half boost at 2/3 the way to redline.
CONS:
Less predictable in initial power delivery. If you are road coarse racing, turbos might not be the best setup.
More expensive usually than the supercharger counterpart. And more intrusive to install.

So I was testing actual high boost, not what I ran at the track, and had 3 clean runs on the dyno. At the end of the third one a rod snapped in half. This was at 930 rwtq... and the amazing part is that its still on the baby turbos.
So we're doing a fully forged engine this time. I don't think I'll be taking the new C7 record, but I do expect to hit a low 9 second pass, and possibly squeak into the 8s while still maintaining factory seats, and AC.

thank you so much, great response to my question, now i would love to see a c7 z06 with this package and the bigger turbo package runing meth, cam etc and see the numbers!

Awesome. It's flat out amazing that a stock engine took that kind of power at all, and that the pistons were STILL ok

Gotta keep AC, otherwise :racecar:
We put in forged pistons while the heads were off. They drop right in and are the same weights as the factory pistons so no need to balance. Had to modify the placement of the piston squirters though.
The stock pistons are iffy around the 700 rwhp/12+ lbs of boost mark.
The forged pistons are running strong even at the power level I was at. In fact on the cylinder that failed when we initially scoped it we could see the piston in its entirety still in the cylinder hah.
I'll be honest, I was pretty bummed I didn't get to make a pass on full kill and sticky tires. But then I thought, what if this happened at 150-160 mph and I oiled the rear tires. Could have taken me with it. I had over 150 loaded dyno pulls on the setup - I tested things thoroughly to say lol.
My impression is that I love the Twin Turbo setup and I'm glad I spent the extra to do it. My 2014 C7 (7Spd) was fun as well, had a YSi on it, but turbos are just much more fun.
Ah gotcha. Yeah that's pretty slick then if you can basically just drop in forged pistons and go. Weak link gone.
Yeah turbos really are fun.. I didn't realize how much fun they were until I tuned/drove an AGP TT fifth gen camaro a few months back. That thing was so much fun, tons of torque compared to centri setup
With 935rwtq coming on that early in the power band, I'm not surprised you broke a rod.
Me either lol. But I was curious how far the "Forged Powdered Metal Rods" would take it as there wasn't much info on their durability. I would rather test limits on my car than my customers.
does this kit fit on a c7 z06 engine? I understand i would ditch the zo6 blower and manifold and put this manifold on instead. Are these oil or oil-less turbos?

It should be able to be made to work on a Z06, may require a different coupler or two to make it work with an aftermarket manifold. We have a few guys interested in going that route so if/when they do it, we'll certainly be posting results!
Its a great build man. Can't wait to see what it does on a built motor. I've got a built 416, but not using it to its potential yet still on a 1500 blower.

Yes our kit will work on a C7 Z06 with some modification.
The supercharger will need to be removed and replaced with an after market intake manifold like Prochargers.
