ok, so...
just got done another full BBK
car used to have a modified garrett 30R ish turbo on it... made 385whp/310wtq at 28.5 psi...
at 25.5ish psi it makes 380/300.. this was a shearer mani with 55 lbs min compressor and .82 hotside
we removed the turbo kit and installed a full BBK with JM fab exhaust manifold, Megan o2 housing, and went to a quieter dual resonator exhaust... Perrin intake..
well, here is the comparison...
now at 27psi...
so a little more boost, other turbo was 7 lbs more than the BBK.
+almost 60wtq!!
take a look at 4200 rpm.. the BBK is up 148wtq... at 5200 rpm its still up 60whp
14.5 psi is at 3150 on th BBK, 4300 on the previous....
24psi now by 3660rpm... and 5000 before for 24psi...
Now, this car has a BR head... runnning about 2 degrees more timing than normal...
Full Mod List:
BBK full 1.5 turn on WGA
Megan O2 housing, Megan Downpipe, Megan resonated test pipe, Cobb catback
780 PTE's, Perrin Intake, Vibrant filter (will be changed to perrin so I expect another 5-8whp from that filter change)
BR FMIC, BR IC pipes
255 fuel pump, small battery
Anyway, a little more food for thought..
