10 or 12lbs with stock pistons?

[SVIPER`]

Im not really new to the performance world. Usually with a good tune and the right gas things tend to stay together. Im just trying to figure out how far people have pushed these stock pistons? I would like to bump the boost up a little. Just enough to get to the 700rwhp range. right now i got the vec 2 on the car and it made 622rwhp making 6.5ish for boost. Im thinking the 10lb pulley should get me there.

Thoughts on the pistons?
My thought is 12lb pulley and 110 octane and maybe push 720's

I have exactly the same setup as you and I was wondering the same question ...

I believe you can do it if you have forged pistons.

I did a post a couple of days ago to increase my torque between 4500-5500 rpm. Got only a couple of answers.

The problem seems to be the heat due to the compression and the restriction in the head. It is well before you hit the piston's and the connecting rod's limitation. There is also a know weakness in the spring system on the Viper. It is better to keep the rev below 5000rpm for longer period and below 5500-6000rpm for a peak. As long as you have forged piston they should be able to handle the boost.

I think he has a 2004.

I think he has a 2004.

2004 + 12lb. = BOOM!!! unless you swap out the cast pistons...

How much boost can you run with a forged motor?
