ECS 1500/Meth/Headers/Cam Dyno numbers
I just got my car (Base 3LT) dyno tuned, and had JHR Performance, in Mooresville, NC install my meth kit running 100% VP M1 Meth, and ECS 1500 supercharger kit with restrictor plate. Boost was at 7psi. I did not have the heads ported, I'm surprised the heads flow well enough for no torque drop off in the top end.
Mods include:
ECS 1500 Supercharger
Alky meth kit single nozzle
TSP Catless Longtube headers and X-pipe
TSP VVT3 cam kit
ARP Head bolts
The car previously made 516 whp with headers, cam, and afe intake. For reference, a header, intake, tune car dyno's around 430whp on this dyno.
I'm running on the stock michelin tires. It spins the tires up to 85 mph. I'll be putting on some 888s soon.
We will also be doing a retune with restrictor plate off in a couple weeks.

Wow great numbers and a very clean graph, nice work! 
You will easily surpass 800 rwhp with the restrictor out, probably closer to 900. Keep some race fuel in the tank besides the meth at that point.
Congrats and enjoy it!

Chart looks good nice number on the rwhp, I don't know the cam spec but would be nice on A LITTLE higher tq number..
But again from the chart looks like it will pull really good. Robert

Hypothetically speaking, I think I would take 590 flat as a pancake (almost) over 630 peaked hard on a street car Robert. Better traction.

On the other hand hell if it breaks fix it are put good stuff in it to start with.
I agree also on the better traction with the 590 tq # but a man will need that on the top end of the track.Doug you know how to paddle one good, you can get it down the track. Still the chart looks really nice & smooth.

From my understanding, a different cam won't change the torque number it will only change the point at peak torque comes on. Peak torque will come on earlier with a less aggressive cam but will drop off on the top end.
I don't know the TSP cam specs, but it's the VVT3 which is their most aggressive cam.
This is an M7.

I know it sounds weird that I plan to daily drive an 800+whp car. Lol
Also, is that much power safe on stock short block?

To the OP one question here WHY. Man the car should be safe & fun for you on the street at this point for a time anyway. If you push it any more you are going to have to redo every running part in this motor, transmission, & also rear gear stuff to get this car to hold up & get a good 60 ft time.

I feel like I could use some more power. I'm not worried about the tranny or drivetrain parts since I don't track the car very often. I'm more of a highway kind of guy. I'm mainly worried about the motor.

That is better on it not being on the track. But then again when you get up 800 to 900 rwhp stuff can still break plus on the highway, it can spin the tires at around 75 to 80 MPH if you nail the paddle. Just what tires you have on it & cond of the road under them...

I did the same thing. Just didn't feel like risking a piston failure over a couple grand. When you spend $20k plus on performance upgrades, it's a worthy investment.

Could you share how the car idle with that cam, also how the car drives in traffic?

Not really at that point, the stock pistons are really over the limit at 800+ so you need every ounce of prevention possible. The slightest detonation at that level and they are done.
Now if you have the pistons swapped and lower compression down, then pump and meth should be just fine.
