Curious what has been the experience of the Buick community of the two different manufacturers in particular the difference in the inverted dome shape.
I have JE pistons in my DLS built power plant and they work just fineCurious what has been the experience of the Buick community of the two different manufacturers in particular the difference in the inverted dome shape.
im not sure which will melt 1st but ive seen a torched cometic and head/ block and the diamond piston was undamaged,it was rather impressive as the cylinder got alittle hotNot the pistons fault but the thin edge is a weak spot that will start to melt before a dish style JE.
Not any more and not for some time, the new dish design is light years ahead in technology too. JE pistons are now wiesco pistons, all the JE stuff was sold off in Cali they are made in Ohio now.
I have not. I can't say that I agree with coating the tops of the pistons for most engines with high cylinder pressure and mass flow. It would likely hold more heat in the cylinder and reduce the detonation tolerance.Mike , Bison , have you either of you built any motors with piston tops ceramic coated ?? I've been reading a lot about it and was wondering if anyone here tried this ?
The squish area present in the Diamond piston will create mixture motion in the chamber for a more even air fuel distribution. This will assist in a more complete and even burn helping to avoid detonation. If folks are torching their pistons, perhaps their tunes relative to dynamic compression could use a second look.

Regular compression ratios confuse most people so I doubt there are a lot of dynamic compression conversations happening here but I'd love to be corrected.
I have GN1's. The chamber is different and a lower volume than the stock irons.Quench area on a piston only works if there's quench area on the heads. Unfortunately, we have very very little on the Buick V6s. When I designed my forged pistons I started out with the intention of maximizing quench as much as possible. That was quickly put to 2nd as I worried more about a dish that would require the least amount of timing to achieve power.
I tend to bring it up often but it never goes anywhere. Since most people like to run big ass cams, dynamic compression tends to be off on the low side in those instances.
