Im not taking sides here. As I'm trying to get more info on the whole subject.
But I don't see any reason to start flipping out and name calling because someone doesn't like ENDYN.
I personally havn't purchased anything or had any services performed on my motor by them either. But I did read some pretty disturbing information. Whether its true or not, I have no way of knowing for sure just by reading old posts at forums.
Here are some things I read. Keep in mind these are NOT quotes, just things I recall reading.
Untill recently Larry's shop was in his garage. (Nothing wrong with this but supposedly he claimed to have huge facilities with lots of machines)
He claimes to use things like flow benches when porting cylinder heads to get "maximum" power and yet someone that claimed they worked for him said he had no such machines (He might have them now, but supposedly he didn't back then)
He speaks like he has lots of employees on his website, always writing "we" this and "we" that, and yet alot of people claimed that he pretended to be more than one person on his forum, so he could act like he was one or more of his so called employees.
The list of accusations goes on and on. Probably the most credible one for me is a post from a guy that I know. He has a shop about 30 minutes away from me. He claims that he sent his crank away to get lightened and balanced and it came back with burs all over it. I think he wrote that larry still had a motor of his for months.
Now none of this is from personal experience, and I don't have any way of proving any of its true. I am going to call that guy from the shop near me though and see what he has to say.
I think the popular opinion around the forums about ENDYN goes something like this
(1) Their pistons and other products are good. (But remember they are just slightly modified versions of products that already exist)
(2) Stay away from their machine work because its not what they claim it to be. It will take much longer than expected to get your parts back, and they won't work as well as expected.
I was planning on using ENDYN before I read these things. Now I'm having second thoughts. I do realize that it's possible that some of this stuff isn't true, because I have no proof for myself. Thats why I want more info.
