Turbo guys - do you use a full dish or partial dish piston??
I am finally getting ready to order a forged rotating assembly for my 99 Z28 engine and I wanted to know if you turbo guys use a partial dish piston with a quench deck OR a full dish piston? I am looking for around an 8.5:1 to 9:1 compression ratio and trying to hit at least 600rwhp.
Also, what pistons (brand, dish, type of dish) and rod length are you guys runinng?
Thanks a lot -Dave

Full dish pistons will make a bit more power, and will also be much more sensitive to detonation.
I would personally never run anything other than a d-shaped dish piston that mirrored the cylinder head, as I place alot of value in squish/quench.

I agree with INTMD8, a partial dished piston (mine are JE -14cc supercharger pistons) helps with quench, by matching the heads quench area. You want a solid 'squirt' across the chamber as you reach TDC. Helps turbulence, suppresses detonation.

This topic has recently come up on another forum and some other threads here.
My question is this? Is anyone running a pump gas daily driven ls1 with a fully dished piston (not reverse dome). I don't see how they would work well at all without the normal quench area. I was surprised when I found out that people were running them at all.
Also curious about the above statement that they can make more power. Educate me!
