Turbo time for my S50 on a "budget"

[BMW_TUNER]

Thanks,

There is no way that stock rods would have held up to more than 5-8psi. I actually went with K1 based off of my engine builders recommendation. Unfortunately, it didn't work out.

Hey,

First sorry to see this happen on a build that was done so thoroughly (very well thought out and executed). I just happened to be reading a blog a few weeks ago written by an engineer comparing H beam rods to I beam rods. Here is a link to that page:

You will need to scroll down half of the page it is in section 6. It looks like that it isn't just your rod manufacturer, but maybe all H beam rods are inherently weak. Again, sorry that your build went this way, it seems looking back the stock rods might have worked for you (but we all know that hind sight is 20/20). Looking forward to keeping up with your progress on your next build. Keep up the good work!

It is all out material failure. I think JE should stick to making Pistons those looked good on disassembly.

So just gross material failure? No evidence of hydrolock...

[BMW_TUNER]

Yeah, google did confirm that. I wonder how their failure rate compares to others. Was it predetonation that caused this?

Megasquirt plug and play is sounding better and better.

Very unlikely as the timing was concervative and the comp ratio was so low.

According to a quick google search....yes.

I do not advise anyone purchase K1 Rods. They did this on 12 psi.

Jeez, that is crazy. I wonder if others have had this experience.

So are you replacing rods and keeping the turbo setup?

No moving on to S54 NA

If this is #2 Rod he ain't that straight any more.

It reminds me of that college question
What is the fastest way between any two points on the face of the earth...........
a curved line, a zig zag or a straight line. Lots of people say a straight line but the earth is curved. HAHA.

Given that it has dropped I could drag out some old geometry and trig and figure out the arc before I pull the bottom end but at this point its safe to say that its bad.

Ive never seen that, crazy...
