Lingenfelter tests supercharged 6.2L Gen 5 engine
LT1/L86 6.2L GM Gen V direct injection (DI) V8 engine:

Stock long block; full accessory drive; stock exhaust manifolds
Stock fuel injectors and fuel pump
Magnuson TVS1900 supercharger
621 HP @ 6517 RPM & 617 LB-FT @ 3417 RPM
19 degrees timing & 6.8 psi boost at peak power.

Here is the dyno chart of that run:

Is this a peak at what the C7 Z06 might produce?

That's a tiny blower at 1.9 liter and it's can't be pushed too far or will generate a lot if heat. Plus, 550hp at the wheels isn't too impressive, but I like the video and the fact blowers are being tested.

Just looked at the dyno chart, I don't like the torque dropping as RPM increases either. This motor is begging for a centri blower or turbos.

Why the TVS1900 Callaway said it will be using the 2300

Thanks Sinner and i10fwy for your posts. Don't know half as much as you two in this area.

What do you think of Eaton's chargers?

Sorry, the blower is most likely a 2300 if the article stated that and it was assumption it was a smaller 1.9 due to saying 1900. Most companies will match unit number to liter size, like Roush TVS2300 is a 2.3 liter.

TVS is more efficient then an eaton but both make great power. Both are considered a positive displacement blower (PD) like the ZR1, ZL1 and GT500 and all heat soak easily. Once heat soak occurs timing is pulled and power drops and while that happens on all blowers, PD are the worst.

The good and bad about these blowers is all the low end torque, it's great for fun and very exciting but it's very difficult to get traction in lower gears.

Thank you very much.

Nice superchargers being tested
