FIrst off I assume my BOV should be oipen at idle. right? due to vacuum? But seeing as it is open during vacuum and doesn't close just before boost could this account for slow spooling of turbo. Boost doesn't hit until 4400rpm on a ZC with a 14b. I'm using a light spring in my BOV, could put the stiffer one in help?

 

i have a 14b on my SOHC VTEC. I have a stage 2 comp cam 59300.

even with my wastegate not lining up properly, i hit 10psi by about 3500 rpm..

 

No, that won't help.

Yes, yr BOV is open in vaccum (at idle).
But, as soon as you press throttle, there is almost no vacuum in intake manifold (gauge should read near 0), and already at that point BOV is closed.

 

how do you like that cam along with boost? I have the same cam in my y8 with the comp cam valvesprings and will be boosting it hopefully by this weekend. So far i have heard nothing, but good things about this cam and turbo .

 

i like the cam, but i want to get it dynoed to make sure it doesnt have too much overlap and to set my VTEC point.

heres the specs from comp....

advertised duration
--------------------------
primary - 232
secondary - 236
VTEC - 260
exhaust - 268

duration @ .050
--------------------
intake primary - 190 @ .050
intake secondary - 194@ .050
VTEC - 220@ .050
exhaust - 216@0 .050

lift
---------------------
primary - .300
secondary- .310
VTEC - .455
exhaust - .430

lobe centerline (degrees)
----------------------
primary - 111
secondary - 115
VTEC - 107
exhaust - 111

 

I wouldn't want my BOV open at idle, I don't wana get any fucing dirt in it and ----.

 

some of the guys on ht were dynoing an extra 20whp with that cam in their turbo setups.
