Just trying to get an idea of how the LT1 is holding up under boost. Please fill out the following-

-Car?
-Who tuned your car?
-Current mileage? If your engine let go, at what mileage and why?
-Mileage when the supercharger was added?
-Rwhp?
-Any issues?

I know you're just trying to gather data to make your own conclusion, but here is the best info I've found from CPR. A shop that probably has some of the most C7 experience.

No failures around 800whp.Only failure was 990whp at the half mile.

The real factor in longevity is the tune.

I just crossed 20K

3K at 545rwhp and 17k at 645 with meth. ECS kit, Dr. Phil tuned.

Zero problems but the meth did finally eat the seals on my second pump so I've replaced the pump twice in three summers of driving.

-Car?
2014 Z51, M7, Vortech Ti trim blower, methanol, headers

-Who tuned your car?
Local shop in Colorado Springs, RMCR aka Wendz Racing

-Current mileage? If your engine let go, at what mileage and why?
Just rolled 20k

-Mileage when the supercharger was added?
14k, self-installed summer 2016

-Rwhp?
~710 SAE

-Any issues?
Traction, the stock tires just spun and spun and spun, first and second gear were pretty much unusable at full throttle. So this summer I got a set of Z06 wheels and the body panels that go with it and now it sticks so much better.

25k miles, Procharger p1sc, 570/530, AMP in Dallas tuned, no other mods. Take it to HPDEs often at 100 degree Ambient, aka beat the hell out of the car. Supercharged half those miles.

2014 M7. Bought car with 3 miles on it. Added headers, intake and tune early on, later added an A&A S trim and dual meth around 30K miles 639hp/618tq. Ran great until I voluntarily rebuilt the motor for more power around 51K miles. Have 53K miles now on a built motor, and have 828HP and 717TQ. Latest build was tuned my Howard at Redline Motorsports. Only two issues I am dealing with are traction for the tires and trying to keep engine temps down lower than what is considered normal.

It's all about not being greedy. Unfortunately everyone wants as much as possible! Its not hard to make a stock LT1 produces 800 HP but how long it lives at that level is the point. If the engine has lived past 2000 its usually home free as far as being valid.

The aftermarket is a big industry for a reason....improvement parts so we can push the engine harder with further confidence. This is why we and many other qualified shops have packages......because we know where the limits are and when its time to step up.
