I ran a boost test this morning of my old engine vs new. Note... I added a +5% overdrive lower with the new setup, which makes the results even better!
Old:
Gen 1 Aluminator
Stock heads/stock cams
BBK 1-3/4" headers
Whipple 170mm mono
VMP Gen 3R, (69mm / stock lower)
dyno pull in 4th
Max boost = 22.5lbs
New:
5.2L
Gen 2 heads (ported by Airflow Solutions/Boss 302 cams)
Stainless Power 1-7/8" headers
VMP Performance 163R
VMP Gen 3R (69mm / +5% <-- adds boost!)
Street pull in second and through 3rd into 4th. (I manually shifted from 2nd to drive once I went wot)
Max boost = 19.5lbs
Even with a +5% overdrive lower and larger throttle body, it still dropped 3lbs.
Is anyone surprised? I was hoping for this, but didn't really know, as everyone seems to go straight to larger cams where I didn't.
