Default So, Why Oval?

This http://www.duramaxdiesels.com/forum/...50&postcount=1 Kinda torqued me off.

Obviously the A$$hat hasn't bother to look into what the heck he is talking about.

Jon, we know. That should be enough. Thanks for all you've done to help everyone.

Hogue is a pox.

Pretty much everything he says is wrong. Why do you think his dragster lives on jack stands. I dropped off my replacement piston with the machinist today, thanks Jon.

Breathe.

Obviously the trade off between real-world survivability and unmeasurable, theoretical efficiency was lost there. Not unexpected for one with a narcissistic personality disorder.

I'll echo what Tom said.

When it comes time to buy a set of Pistons for my rig I know what I'll be buying.

I went with ovals cause they are PROVEN. Have been pushed to the limits. With updates of failures and what caused them. Also the price is great for what they are.

Hogue is the biggest f'n retard I think we have ever had to deal with period. We run your Oval bowls for a reason, they work! We are running 8.5xx's at 161mph @4500+lbs on cast oval bowl pistons without a single issue! No one else would ever even think about running a cast piston at this kinda power range but they do exactly what they are designed to do! Thanks Jon for a great idea that has proven to work in the real world!

The concept of the oval bowl and why it was created and is widely used is lost on him apparently. He'll probably invent it in a few years then it will be a great idea.

I commented and said (in a short way) what mark said and Greg told me the oval was a "sales gimmick". I asked how known strength and durability was a gimmick. Then the thread was closed lol.

I wanted to hear Gregs response so bad.

I don't understand why the mods haven't kicked him off the site yet. I hate people that act the way he does. For him to say something about oval bowl pistons and say they are a gimmick!?!? I'm embarrassed just by living in the same state as him! Jon, I've been running ur Pistons for awhile now, nowhere near as much power as Brett or some of the sled pullers, and I love that I can hammer on it and not have to worry about the Pistons giving up!!! Great work.

Greggy didnt think of the design therefor his narcissistic self must discredit the designs ability, so he can feel better about himself.
