I finally got a turbo charger drive pressure sensor installed and now have a better picture of what all them spinny-things are doing.
Line Number 55 ~ 67: Pretty-much driving 55mph or so, trying to hold a steady 10psig boost.
Line Number 276 ~ 285: Short/WOT, #2 only.
It looks like a drive-pressure ratio of approx 1.5/1 under WOT conditions.
NOTES:
- The turbo charger's pressure sensors are located on the compressor housing's outlet.
- The intake log pressure sensor is in the common location next to the throttle linkage.
- It appears at WOT, there's about a 3psig pressure drop from the secondary's outlet, to the intake log (That accounts for the IC and all charge-air related plumbing, the associated temperature/pressure drop, etc.
Unrelated . . .
The other day, we were talking about IP timing and jumping teeth. I was right at +2 teeth (2.8mm plunger lift). Wanna said "Great Scott!".
I got to wondering if maybe I was past the sweet-spot IP timing wise, so I made a few passes at the local 1/4th mile track making a baseline and moved around the IP timing . . .
Stock timing mark + 2 teeth: 13.48 @ 97.42mph. (Boost: 56ish).
The above retarded approx 1/8": 13.77 @ 96.96mph. (Boost: 60psig).
2 teeth + "A Little": 13.36 @ 98.38. (Boost: 52ish).
Going from the HX35-Hybrid to an S300 62/14 (as a secondary) has initially slowed me a little changing nothing else.
Otherwise, EGTs are down a solid 150*F (no2 only).
The IP's the only thing left to bomb now.
YeeHaa!
