Dyno numbers... 317 whp and 314 tq at 10 psi *turbo*
I forgot to post an update in the 5th gen forum with the dyno results since some of you guys/gals don't go into the other forums. Here goes (original thread in General Forum) :
Well, I have been running extremely lean for the past 3-4 months because the Walbro intank fuel pump wasn't working correctly. The pump would not put out the pressure and flow needed for anything over 4 psi. Best of all, I didn't find out about the bad pump until 2 weeks ago. So, get an in-cabin fuel pressure gauge!!!
Run #1: 317.3 whp, 314.4 tq
Run #2: 311.9 whp, 318.7 tq
Run #3: 308.5 whp, 317.4 tq
Here goes the dyno graph (best SC = red, best TC = blue):
We did 5 runs total, with each run putting out less and less hp after 5225 RPM. The largest difference in power (with all 6 cylinders semi-working) at 6500 is about 130 wheel hp and 120 ft-lb torque.
Here are pictures of the plugs after run #4:

I wasn't running the Aquamist water injection on the turbo dynos since the pump broke (found out 1.5 weeks ago). Both SC and TC dynos weren't fully tuned, so it may not be fair to compare the two without them being at their best hp and tq.
Did a compression check when I got home. Cylinders #1 through 5 are good, but #6 is a little weak.
Lesson of the day: Get an in-cabin fuel pressure gauge.
