Eric's E92 build

[The Convert]

Ok it's been awhile since my last post. Fixed problem wit turbo sucking oil past the seals. Raised oil drain into pan and put check valve on sump line behind turbo. While dyno tuning car I found out that two of my ID1300 injectors were newer versions than the rest and causing misfires on one bank. Replaced with ID1050x injectors and all is well. I maxed out DI @ 880WHP and started tuning for PI after that. Car should be ready for wanna go fast event in Ocala Fl. next week. Here is graph of last DI only run.

Can you post a pic of the new oil return setup? Gracias!

 

[Chris@VargasTurboTech]

This a fully built motor right? Why are you revving it so low? Outside of that, power looks good for DI only. What does the graph look like with PI on top?

 

[tisdrew]

Could he be revving it "low" on the DI-only map because there isn't enough fuel up top?

Curious to see your 1/2 results and if you break 1000whp on PI.

Ok i'll snap some pics later on today.And here is a graph while tuning the PI

Definitely having issues above 6500, looking forward to you getting them sorted, and spinning that bad boy to 8K...

Wanna go fast event didnt go well for me. First day was canceled due to rain and I blew 4th gear in my trany the next day. Guess 800 ft lbs of torque was too much. Lol.

I'd be willing to bet the input shaft snapped due to impulse shock...

 

[Erichale77]

I dont think so. Trany threw a code for 3-4 gear ratio error. Forgot what exactly code was in xhp but first thru 3rd gear still works. Just wont shift into 4th.

I'd be interested to see some tear down pics for a root cause and failure mode analysis

If this trany is toast I dont plan on throwing more money at it. I might consider a sequential.

Would be worth the time to tear it down and see what happened though. Then toss it or make some garage art. Haha

 

[Erichale77]

Oh were going to look at what happened to it. Jason G seems pretty sure the input shaft snapped from impulse shock. But if that's the case I might consider throwing a Drenth in it. That way I can still use the paddle shifters.

Could you produce this graph with SAE correction?

Solid! Post this and your basic specs on the 800 hp thread and I'll add you

That's got input shaft prison rape written all over it hahahahaha
