GOT HER BACK GUYS!

^Phew!!! Just in time. When we'd see m54's come into the shop needing a DISA we were always worried the pin would be precariously sitting somewhere waiting to fall into the intake runners.

[Happy]

Yeah that one was pretty close. The video actually exposed the issues. In the first pass we could hear 3 slight misses in the top of second gear. I think the MAF was the primary cause, however decided to inspect the DISA. I was pretty shocked.

Took her to the top a couple times in second gear and no missing. They were definitely due, there was a moderate power gain.

The blow off is pretty nasty on this build. Remember there is a MAF, so it’s not atmospheric.

Anyone agree?

Blow off or blow by?

Is tuning available to make it MAP based vs MAF based?

So Crystal I think you are correct. It would be blow by right?

I did not choose alpha-n because of smog in California. I was able to pass at least twice, which worked out well. Visual was overlooked.

In Texas we still have inspection. I wanted the X5 to able, under any circumstances.

So, if it’s blow by and the microphone caught that release of pressure, I would say the RMS kit it pretty aggressive.

Right?

Andrew, Overboost, and Bcredliner. I would like to hear your feed back as well regarding reprogramming.

[crystalworks]

Does it have a "blow off" valve? I'm more familiar with turbo than supercharger but I would think you would still want the pressure to be released to atmosphere after lift off.

I was asking if you meant blow by, oil/boost making it past the piston rings. Wasn't sure what you were referring to in post 23.

[Happy]

It does, but I think you refreshed my memory that it is a bypass vs blow off. If it were to blow off MAF would detect irregularity, so it puts it back into the system.

I rarely drive the X that hard but I was shocked myself to hear what sounded like blow off.

There is no blow by from the rings, but it’s a bit rich. That’s why I’m mulling of the idea of reprogramming, because how darn hot it get here during the summer.

I just keep hear an old saying, “leave well enough alone”. LoL..

Kinda does sound like a Cummings. It’s gotta be the torque?

Right?

Love the supercharger intake sound.

Come to find out Crystal, I was losing 3lbs of boost during this shoot, faulty valve cover gasket. Plus my adaptations were faulty as well. Bad MAF, bad DISA, and boost gauge failed, causing a severe vacuum leak.

With all the repairs, 11lbs of boost. 14 x 11 = 154. Plus 30hp from the meth. 230 + 154 + 30 = 414. Definitely S62 power.

Tell me more about this diesel sound.
