now for some FI friendly cams... hehe
add a ITR exhaust cam and retune...
boosted applications need less overlap
17-20something should be fine...but
like skunkstage1 is 35... not ideal
and more duration/lift on the exhaust
side to scavenge more power.

GSR/GSR
10BTDCin.open/7BTDCex.close
boost builds intake pressure and
it needs to be relieved quickly to
make power.. cam gears can help
this retard intake, retard exhaust
and retune the ECU for peak timing/
air fuel.

GSR/ITR
10BTDCin.open/10BTDCex.close
more lift and duration on the exhaust
side makes intake pressure slide from
the motor more efficiently, therefore
scavenging more power from the motor
moving it under boost more mechanically
efficient, increasing transient response.

I think this is the way to explain it to
sound smart.

tune them and rechip: for example try this:
GSR/ITR cams
retard intake 2-3deg/retard exhaust 2-3deg
8BTDCin.open/12BTDCex.close > 20deg biased
toward exhaust duration=good for boost :naughty:

that midrange power is exeptional, good peak #s
excellent tq all over the place... that car must be
a demon!@

I really would like to see someone build a chart with
cam tests for supercharged apps. I know of JRSC honda
builder here in FLA that uses the ITR ex cam and sees
good numbers, the hondata in your case is doing an
exeptional job kudos on a well tuned setup!!!

I wonder how a skunk2 stage1 exhaust cam and CTR
intake cam would do? or sk2s1 with GSR intake cam...
musing is fun...
