Been a busy weekend! heres how she looks right now all finished.



Finished up the turbo install. Couple of fuel leaks and she fired up and sounded so good. Then the oil return line failed and dumped oil on the ground. Damnit jim. I guess you can't clamp braided lines with hose clamps. luckily for me, Jason had a 10AN to hose barb so i can install the new return.

I also noticed I hooked my coolant feed/return up on the EFR wrong. Need to swap those but i have to take them off anyway to pull the return.

meanwhile, its supposed to snow this weekend.

Figure I could provide an update on this turbo... Here is a comparison of the old turbo (4th gear) on E85 in S# vs the 7163 (3rd gear) on E66 in S-mode. As ethanol content comes up, so will boost in both S and S#. Now that boost is set in S-mode, timing will be added and AFR leaned out, but we've almost got S# set... Just waiting on another log.


I think S-mode will make more power than the last setup did at all.




I-mode boost, which is just wastegate spring. This will be the same for E0 - 100.

"Rough Draft" of SI modes on E66.

Car pulls so hard. I am in love with this turbo. Seriously, and we aren't even done tuning.

On a side note, the EFR does not like the Tial BOV. so im switching back to the provided BPV.

That seems like a great plot. Especially for the lower cost pressures. 25 psi and nearly 480whp is great.

How is transient response? When does the turbo come on to boost?

I imagine the transient response is just as good as my 6758. If it weren't for the FMIC piping and stock manifold, I'd say it'd spool a lot like mine as well. The 24 PSI graph is a little soft as it spools towards the top. It should improve on the last map I sent him.

I'll have him do a 4th gear pull soon and see how that affects the boost threshold. Once the ethanol content comes up, it should be around 26 PSI at our altitude.
